v1.4.28

Added console.getcursorpos() to get the cursor position.
Updated os.getscreeninfo() to include the cursor position.
Changed character width measurements in Windows Terminal to accommodate certain fully qualified color emoji variants such as "✔️" vs "✔". The former is U+2714 U+FE0F and Windows Terminal draws a double-width color emoji; the latter is U+2714 and Windows Terminal draws a single-width character in the current font. Note that Windows Terminal draws the characters; Clink just tries to make the best prediction it can about how Windows Terminal will draw the characters.
Fixed display glitch where auto-suggest caused the display to scroll up an extra line at the bottom of the screen.
Fixed display glitch where cursor position was wrong when the input line ends with a history expansion directive that ends exactly at the right edge of the terminal.
Fixed cmd.ctrld_exits so Ctrl-D always exits with return code 0, so that terminal programs allow the shell window to close gracefully.
Fixed mouse input when the horizontal-scroll-mode inputrc variable is on.
Fixed missing prompt text when a prompt filter encounters an unhandled Lua error; now a placeholder prompt string is used so it's clear where the prompt is.
Fixed #467; On-Screen Keyboard in Swedish keyboard layout can't type \.
Internal improvements.

v1.4.27

Fixed when the terminal.emulate setting is auto on Windows 8.1 and earlier (regression introduced in v1.4.26).

v1.4.26

Added built-in support for shell integration with Windows Terminal v1.18 and higher. Note: Windows Terminal gets confused about the command line text when the transient prompt is enabled.
Changed clink.getansihost() to return two strings; the first string is the mode in use, and the new second string is what Clink detected (and will use when the terminal.emulation setting is auto).
Fixed to use terminal emulation when the terminal.emulate setting is auto and ANSICON is present. Clink's output is no longer able to be intercepted by ANSICON, so bypass it and use Clink's own terminal emulation.
Fixed #461; crash due to invalid RVA in ANSI32.DLL or ANSI64.DLL (ANSICON).

v1.4.25

Now os.issignaled() works during onendedit and onfilterinput events.
Improve emulation for F7 history popup (the win-history-popup command); Left or Right replace the input text with the selected line.
Transient prompt filters can suppress the transient prompt on a case by case basis by returning nil, false.
Fixed typo in clink set --help text.
Fixed where the prompt prefix (from v1.4.24) is inserted in the prompt string, so that shell integration escape codes can work properly.
Fixed #457; unrecognized OSC escape codes accidentally stripped from prompt string.

v1.4.24

Added path.fnmatch() which behaves like the Linux fnmatch(3) function.
Added os.globmatch() which performs recursive file pattern globbing the same as git does.
Added support for %CLINK_PROMPT_PREFIX%, %CLINK_PROMPT_SUFFIX%, %CLINK_RPROMPT_PREFIX%, and %CLINK_RPROMPT_SUFFIX% to provide prefix/suffix strings to surround the prompt strings, and for prompt filters to define a :surround() function to add their own prefix/suffix strings if needed.
Fixed ~ by itself to change directories, the same as ~\.
Fixed horizontal scrolling in popup lists (is possible whenever the item doesn't fit and no items contain control codes).
Fixed #452; history delete # doesn't work (regression introduced in v1.1.43).
Fixed #448; completion malfunction with ..\does_not_exist (regression introduced in v1.4.1).

v1.4.23

Added help message in clink-select-complete: when descriptions are shown below the matches, this adds text to mention that F1 toggles showing descriptions inline with the matches.
Added clink update --check to only check for an update without installing it.

v1.4.22

Fixed clink-select-complete to use per-match appendchar when present.
Fixed repetitive unnecessary work in the background when the completion auto-suggest strategy encounters a fromhistory argument slot in an argmatcher.
Fixed the installer /S flag (silent install) so it returns exit code 0 on success.

v1.4.21

The clink-diagnostics command can report merged argmatchers. When a numeric arg of 2 or greater is given (e.g. Alt-2,Ctrl-x,Ctrl-z) then it includes a list of defined argmatchers. The list now also reports any merging of argmatchers that occurred.
Fixed clink update so winget doesn't get confused about whether an update is available for Clink. Once winget update clink performs an update, or once a Clink v1.4.21 or greater .exe installer is run, then winget should stop getting confused.

v1.4.20

Fixed os.isfile() and os.isdir() when the specified name contains < or > or ", which are special wildcard characters for MS-DOS compatibility. This caused an error when typing "<, which then mistakenly thought a completion script named <.lua existed.
Fixed rl.expandtilde() to omit a trailing backslash when expanding ~ by itself. This is to avoid running afoul of the \" parsing rules for argv[] for programs.
Fixed potential crash when the clink command line takes more bytes as UTF8 than it does as UTF16.

v1.4.19

Added builder:setforcequoting() to force quoting rules to be applied to matches even if they aren't filenames. This also reverts "quoting for non-filename completions" in v1.4.13; there isn't a safe and backward-compatible way to automatically deduce when non-filenames matches need quoting, so a match generator needs to turn it on explicitly when desired.

v1.4.18

Added clink.oninputlinechanged() to register a function to be called whenever the input line is changed.

v1.4.17

Added os.isuseradmin() to get whether CMD is running as an admin account.
Added os.getfileversion() to get a table with version information if the file contains a Windows version info resource.
The clink-diagnostics command now reports costs for Lua event callback functions when a numeric arg is given (e.g. Alt-1,Ctrl-x,Ctrl-z) or when the lua.debug setting is enabled.

v1.4.16

Added history.show_preview setting that controls whether to show a preview of history expansions (previously it was inferred by whether color.histexpand was set).
Added detection for problematic codes in the prompt string. The clink-diagnostics Ctrl-X,Ctrl-Z command reports problem codes in the prompt string. When certain problem codes exist in the prompt string, then Clink compensates by reprinting the entire input line after printing the prompt string. Ideally, the prompt string should be fixed by the user, but sometimes that's difficult if the prompt string was generated by a tool.
Potential Breaking Change: Fixed how hidden and system files are handled by os.globdirs() and os.globfiles() (it had never worked properly). It worked fine with the default modes of the files.hidden and files.system settings and match-hidden-files config variable. But if any of those were changed from the default values then malfunctions could occur. With the fix, in backward compatibility mode the files.hidden and files.system settings and match-hidden-files config variable control whether os.globdirs() and os.globfiles() find hidden or system files, as before, and things can potentially malfunction. When the optional extrainfo argument is non-zero or when a new optional flags table is passed to them, they now default to including hidden files and omitting system files, but the flags table can override that. This change was necessary because some scripts were unable to detect git repositories when the files.hidden setting was false. Excluding hidden files never worked properly in the past. Clink v1.4.16 does its best to be as backward-compatible and forward-compatible as possible, but in some cases scripts may need to be updated to work properly when the settings or config variable are changed from their default values.
Fixed the match-hidden-files config variable to work again (regression introduced in v1.0.0). Also, when off, now it hides files and directories whose names begin with ..
Fixed #421; clink.bat errors with quoted arguments (regression introduced in v1.3.47).
Updated documentation with more cross-referencing links for Clink settings, Readline commands, Readline config variables, and standard Lua APIs.

v1.4.15

Added log.getfile() to get the current log file path.
Fixed match display to better accommodate escape codes for italics and underline, if present and supported by the terminal.
Fixed #414; argument color doesn't reset for values in multi-column layout when colored-stats is off.
PR #418; Fix crash caused by destruction of non detached threads.
PR #417; Fix buffer overread caused by usage of strcmp on non null-terminated char arrays.

v1.4.14

Fixed autosuggest to update again if matches are marked as volatile and the input line changed while matches were generated in the background (related to clink-completions#164).

v1.4.13

Added more status information in clink-diagnostics Ctrl-X,Ctrl-Z.
Fixed quoting in the insert-completions Alt-* command.
Fixed quoting for non-filename completions.
Fixed a CPU busy-loop after match_builder:setvolatile() was called during an autosuggest strategy.
Fixed #411; setting %CLINK_HISTORY_LABEL% after Clink started didn't take effect (regression introduced in v1.3.18).

v1.4.12

Additional improvements and logging for East Asian ambiguous width characters.
Running clink inject no longer empties the log file, so that AutoRun doesn't result in the log file being cleared over and over, which interferes with diagnostic efforts.
Fixed #407; the complete command gets confused by . prefix on files.

v1.4.11

Fixed #406; the "lambdagenerated.omp.json" theme for Oh-My-Posh has problems in CJK codepages. The East Asian Ambiguous support has been rewritten to solve multiple subtle issues; the fix in v1.4.9 exposed other inaccuracies.

v1.4.10

Added optional level argument to log.info() to facilitate more accurate reporting about the calling code.
Fixed extra duplicate log entry when the updater finds that Clink is already up to date.
Fixed #405; vi search gives unexpected results (regression introduced in v1.4.7).
Fixed #402; for convenience, print the Clink Releases page URL after a successful update (takes effect on the next upgrade after v1.4.10).

v1.4.9

Improved the problematic character reporting in the clink-diagnostics command.
Fixed measurements for the East Asian ambiguous width characters (this should solve the Cmder problems with lambda in the CMD.exe prompt text, including the space after the lambda).

v1.4.8

Added rl.needquotes() function to check whether text needs quotes in a command line.
Changed the terminal.color_emoji setting auto mode to more broadly support accurate width measurements for color emoji (regardless whether the terminal program is capable of actually drawing the color emoji).
Now clink-diagnostics Ctrl-X,Ctrl-Z automatically analyzes the prompt text for problematic characters, reports them, and offers suggestions for how to solve problems they might be causing.
Fixed the completion autosuggest strategy so it doesn't provide a suggestion that requires quoting if the command line input is not currently quoted.
Fixed overly aggressive detection of color emoji (regression introduced in v1.4.7).

v1.4.7

Clink now supports ARM64.
Clink now recognizes when the terminal host is WezTerm.
Clink now supports color emoji in Windows Terminal and WezTerm, according to the Unicode v15.0 standard. The new terminal.color_emoji setting controls when Clink assumes the terminal supports color emoji (color emoji are rendered using double-width characters, which can interfere with cursor positioning math, so Clink needs to know whether the terminal supports color emoji).
Enabled Readline's support for non-incremental vi-mode search (N, n) to search for a shell pattern using fnmatch(), as Posix specifies.
Fixed obscure issue when a "luafunc:" macro modifies the input line and then invokes a completion command.
Fixed line_state:getword() and line_state:getendword() to not strip quotes during generator:getwordbreakinfo() functions (regression introduced in v1.1.24).
Fixed #393; backward compatibility issue when clink.arg.register_parser() is passed something that is not a parser at all.
Fixed #111 again; cd ..Tab didn't complete to ..\ (regression introduced in v1.3.1).

v1.4.6

Added a more informative exit code from clink inject. It returns 0 if successful, 2 if a fatal error occurred, or 1 if a non-fatal error occurred (such as Clink was already present; related to cmderdev/cmder#2800).
Fixed #382; %CLINK_PROFILE% doesn't supersede --profile (regression introduced in v1.0.0).

v1.4.5

Improved debug Lua messages; Clink's built-in Lua scripts reported "?" as the filename, and now they report "{filename.lua}".
Fixed potential for a crash in clink-help when including unbound "luafunc:" macros for which custom descriptions have been provided (e.g. Alt-4 then Alt-H).

v1.4.4

Fixed the screen width in the Help commands and Completion commands (regression introduced in v1.3.43).
Fixed to not load the same Lua script more than once from a completions directory when the Lua script doesn't define an argmatcher.
Fixed architecture reported by clink-diagnostics Ctrl-X,Ctrl-Z (regression introduced in v1.3.49).

v1.4.3

Added backward compatibility for obsolete clink.quote_split(), clink.split(), and clink.get_screen_info().
Fixed empty completion list when typing two letters in rapid succession when both the autosuggest.enable and autosuggest.async settings are enabled.

v1.4.2

Fixed path abbreviation in some cases.

v1.4.1

Added os.abbreviatepath() and os.expandabbreviatedpath().
Invoking completion expands abbreviated paths when the new match.expand_abbrev setting is enabled.
Fixed displayed matches for c: or c:dir\.

v1.4.0

Added clink.getpopuplistcolors() to get the default popup list colors.
Added clink.refilterafterterminalresize() to enable automatic prompt refilter after terminal resize. Prompt filters should only enable this if they're designed to refilter very quickly, otherwise they may cause responsiveness problems.
The clink.popuplist() function allows the items table to include fields to override the height, width, colors, and direction of the list.
The clink_settings file format has been relaxed slightly to accept trailing whitespace after a Boolean setting's value. Note that manually modifying the clink_settings file is not supported; always use clink set to query or change Clink settings.
Fixed an obscure crash in the Readline library inside the reverse-search-history command when pressing the first key of a multikey binding (e.g. Ctrl-X) and then pressing any key that does not follow the first key in any of the corresponding multikey bindings (e.g. Esc).
Fixed leaked file handle when history.save is False.
Fixed #370; Tab inside set /p var= mistakenly discards any previous input.

v1.3.51

Fixed :setendofflags(); it made -- work correctly for input line coloring, but it didn't work correctly when generating match completions.
Fixed obscure edge cases where matches returned by Lua scripts could display incorrectly in clink-select-complete, or could potentially even crash if Lua scripts returned invalid results from the ondisplaymatches or onfiltermatches events.

v1.3.50

Fixed the prefix highlighting when displaying matches.

v1.3.49

Autorun detects non-interactive CMD process earlier, before injecting the Clink DLL. This can improve performance somewhat, and may be able to reduce spurious problems with antivirus tools (such as described in #367).
Updater deletes zip file if it fails to unzip. This can help automatically recover from a damaged zip download.

v1.3.48

Fixed another #356 case; trailing spaces at end of display were sometimes optimized away by mistake (regression introduced in v1.3.43).

v1.3.47

Removed the message "Clink autorun is disabled by CLINK_NOAUTORUN".
Fixed #361; detect %CLINK_NOAUTORUN% faster.
Fixed another #356 case; end of display line not cleared sometimes (regression introduced in v1.3.43).

v1.3.46

Fixed right-side prompts on Windows 8.1 (they never worked correctly on Windows 8.1).
More fixes for #356; input line display garbled on Windows 8.1 (regression introduced in v1.3.43).

v1.3.45

Fixed the history expansion preview when the input line grows or shrinks to use a different number of screen rows.
Fixed "cd" so it doesn't match the cd argmatcher, because CMD commands cannot be quoted.
Fixed #356; input line display garbled on Windows 8.1 (regression introduced in v1.3.43).

v1.3.44

Fixed #348; pasting in ConEmu or Windows Terminal duplicates the 2nd character (regression introduced in v1.3.43).

v1.3.43

Added clink.max_input_rows setting that limits the number of screen rows to use for displaying the input line, scrolling as appropriate if the input line exceeds the limit.
Added color.histexpand setting. When this is configured with a color, then Clink highlights history expansions in the input line and shows a preview of the expansion that will be applied near the current cursor position.
Added history.auto_expand setting. When this is set to false, history expansions will not be performed automatically upon Enter, but they may still be performed by invoking expansion commands such as clink-expand-history Alt-^, or clink-expand-line Alt-Ctrl-E.
When a coroutine error happens, write a Lua traceback to the log file.
The clink-diagnostics command now reports costs for prompt filters and input line coloring classifiers when a numeric arg is given (e.g. Alt-1,Ctrl-x,Ctrl-z).
Fixed the input line color when the command word is an alias and a directory and has an argmatcher (regression introduced in v1.3.40).
Fixed how the inserted completion is highlighted while using clink-select-complete with the match.substring setting enabled.
Fixed Readline bugs in the numeric arg input state;
- Numeric arg overflow check was missing in certain cases.
- Numeric arg input state could accidentally empty the prompt string.
- Numeric arg input state accidentally continued showing the arg input message after using Alt-- while already in numeric arg input state.
Fixed some minor input line coloring and completion mistakes for clink set.
Fixed quoted-insert followed by Esc, so that it inserts the raw ESC character.
Fixed how Esc is handled in isearch mode (e.g. Ctrl-r); it should terminate isearch without reverting the input line.
Fixed what-is to consistently reset the color afterward.
Fixed vi insertion mode when terminal.raw_esc is enabled, so that Esc changes to vi command mode.
Fixed clink.refilterprompt() to report an error upon invalid usage (it cannot be used inside a prompt filter, as that could cause infinite recursion and a crash).
Fixed #344; history prints UTF8 text incorrectly.
Fixed #342; typing foo.abc doesn't recognize foo.abc.cmd.
Fixed #340; various display glitches in the Readline library (Clink now uses custom display routines instead of the Readline display routines).
Fixed #339; %CD% doesn't expand.

v1.3.42

Added console.checkinput() to check whether input is available.
Changed console.readinput() to accept an optional no_cursor argument to avoid changing cursor visibility or position.
Fixed #320; resizing the terminal can garble the prompt (bash has the same problem, so Clink now uses custom code to handle resizing the terminal).

v1.3.41

Added io.truncate() to truncate a file.
Added string.comparematches() to compare two matches; this is normally not needed because Clink automatically sorts matches, but some match generators may prefer to disable the automatic sorting and perform custom sorting.
Added rl.describemacro() to associate descriptions with luafunc: macros (or any macro), to be shown in the clink-show-help and clink-what-is commands.
The clink.popuplist() function now accepts a callback function to be invoked when Del is pressed.
The colored-completion-prefix configuration variable now works with match display filtering, provided the display strings only prepend or append to the match strings.
Removed the obsolete clink.gui_popups setting.
Fixed the completion-prefix-display-length configuration variable in various cases.
Fixed timing condition that could potentially crash (regression introduced in v1.3.40).

v1.3.40

Clink now has an icon, and also includes some colored icons for color-coding your shortcut files, terminal tabs, and etc.
Avoid mis-coloring a directory name as though it is an argmatcher (uses a background thread to stay responsive).
Fixed command word completion after :chaincommand(). Now cmd /c Tab works properly.
Fixed :chaincommand() to work properly in a nested argmatcher; it should imply :nofiles() otherwise it can pop out to the previous argmatcher instead of chaining.
Fixed cmd argmatcher to only chain after the /c and /k flags, to more accurately match actual cmd.exe syntax.
Fixed backward compatibility for argmatchers using the old v0.4.9 APIs with functions as argument options (regression introduced in v1.2.7).
Fixed the clink-select-complete command with match display filtering.

v1.3.39

"Use enhanced defaults" now includes history timestamps.
Fixed delay while loading the history file when history timestamps are enabled (regression introduced in v1.3.18).
Fixed suggestions to resume after fully accepting an input line suggestion and then changing the text (regression introduced in v1.3.29).
Fixed reporting unbound commands in clink-show-help when arg is 4 (Alt-4,Alt-H) (regression introduced in v1.3.9).
Fixed to normalize path separators in a fully qualified pathname when using clink.argmatcher(full_path).
The documentation now shows a link icon when hovering over any heading or API name, to make it easy to copy and share links.

v1.3.38

Added clink.recognizecommand() function that input line coloring classifiers can use to find whether to color a word as executable. This is the same mechanism Clink uses internally, and the analysis is asynchronous.
Now clink.argmatcher(command) may be passed a fully qualified pathname for command to enable different argmatchers for programs with the same name.
Fixed argmatcher lookup to favor doskey aliases, so that e.g. "dir" can be aliased to an alternative program but " dir" can invoke the built-in dir command, and they can each have separate argmatchers.
Fixed the oncommand event to also fire when the command word offset changes, because adding/removing a leading space can change whether the command is an alias, which can make the typed command word resolve to a different file or program to invoke.
Fixed line_state:getcommandoffset() when the first word is quoted.
Fixed line_state parsing for input lines such as foo.exe&, so that the exec.enable setting can generate matches properly.
Fixed completion so that CMD command names are not among the completions when preceded by a quote.
Fixed color.argmatcher color to not overwrite custom colors that may have already been applied.
Fixed ^ to not be a word break character when parsing the input line.

v1.3.37

When argmatcher:addarg() is passed a table containing loopchars="chars" then the chars are treated as delimiters for a single argument, and they do not move on to the next argument slot in the parser.
Added clink.parseline() to parse a string into one or more line_state objects.
Added os.getdrivetype() to get the drive type for a path; especially useful if your code needs to skip network paths.
Added match_builder:setvolatile() to force the matches to be used only once. This makes it possible for match generators to produce different kinds of matches based on what has been typed, e.g. an email address match generator could list user names until @ is typed, and then list domain names.
The clink-diagnostics command now lists registered argmatchers when the numeric arg > 1 (Alt-2,Ctrl-x,Ctrl-z).
Rewrote the path parsing routines to properly respect UNC paths and \\?\ syntax and \\?\UNC\ syntax.
Fixed clink.print(NONL, etc) to not print a TAB character after a NONL that is the first argument.
Fixed #329; file completions may be mistakenly marked as directories (regression introduced in v1.2.36; affects only backward compatibility mode).
Fixed #326; rl.expandtilde() doesn't have a way to expand tildes everywhere in an input line string.
Fixed #325; potential hangs while typing if %PATH% contains a UNC path.

v1.3.36

Incremental search in clink-popup-history now centers the found item if it is scrolled out of view.
Tilde expansion is supported for all Lua script directory names and for the %CLINK_PROFILE% environment variable (but there is a quirk, and for the profile directory tilde expands to %LOCALAPPDATA% for backward compatibility purposes).
Fixed some tilde expansion issues; quotes weren't always recognized, and embedded tildes could in some cases result in malformed paths.
Fixed semicolon delimiter in %CLINK_COMPLETIONS_DIR%.
Fixed stack exhaustion crash when using inject --profile nul.
Fixed detection of device names when coloring command words; a device name anywhere in a path is not a valid executable.

v1.3.35

Fixed finding a completions directory under the profile directory.
Fixed finding a completions directory under script directories set via clink installscripts.
Fixed clink.refilterprompt() when the prompt wraps past the edge of the screen and a right-sided prompt string is present.
Fixed rl.getpromptinfo() when the prompt wraps past the edge of the screen (the promptline and inputline fields were inaccurate).
Fixed consistent sort order for completion matches that differ only by case.
Fixed undo (Ctrl-z) after using clink-reload (Ctrl-x,Ctrl-r). This also fixes rl.ismodifiedline() after clink-reload, which was causing clink-flex-prompt to show a modmark after clink-reload.
Fixed #321; incremental search not working in the clink-popup-history command (regression introduced in v1.3.19).
Fixed #320; prompt becomes garbled when prompt is updated by async prompt filters and wraps past the edge of the screen and a right-sided prompt string is present.

v1.3.34

Improved error reporting in lua.debug mode for coroutine failures.
Fixed argmatcher flag definitions that begin with + (regression introduced in v1.3.11).
Fixed the updater when there are PowerShell configuration problems that cause internal errors unrelated to Clink's use of PowerShell.
Fixed potential coroutine failure if a delayinit argmatcher is still running after a new input line begins (regression introduced in v1.3.29).
Fixed os.getfileattributes(), os.isfile(), and os.isdir() to fail as intended when the input includes a wildcard (regression introduced in v1.1.0).
Fixed potential Lua error when typing a command name that included a wildcard, if the wildcard matched a file in a completions directory (regression introduced in v1.3.23, due to the os.getfileattributes() issue above).

v1.3.33

The io.popenyield() function now also returns a function that can be used to get the exit status from the command.
Fixed io.popenyield() for some programs (such as FC and XCOPY) that fail to start if the stdin handle is empty.
Fixed #312; slow startup due to inefficiency in the updater check at startup (regression introduced in v1.3.26).

v1.3.31

Reverted the v1.3.29 change to file:close() that returned the process exit state even after io.popen() or io.popenyield() in a coroutine. It had subtle negative side effects.

v1.3.30

Fixed the menu-complete family of commands for fromhistory argmatchers when autosuggest.enable is enabled.
Fixed #311; "The handle is invalid." (regression introduced in v1.3.29).

v1.3.29

Fixed how Right and etc work after fully accepting an input line suggestion. It shouldn't immediately show a new suggestion when the current suggestion is fully accepted (until the cursor is moved or the text changes), and win-cursor-forward shouldn't append characters from the previous command (e.g. when clink.default_bindings is windows). Otherwise holding or double-pressing Right can accidentally turn into something the user didn't intend.
Fixed double-loading completion script when a command word includes a path component (e.g. "c:\clink_dir\program.exe" mistakenly attempted to load "c:\clink_dir\program.lua" instead of loading "program.lua" from the completions directories).
Fixed delayinit argmatchers so they don't get orphaned if a new input line starts before they finish.
Fixed file:close() to be able to return the process exit state even after io.popen() or io.popenyield() in a coroutine.

v1.3.28

Fixed #309; some locales fail to parse the PowerShell version number.

v1.3.27

Added more detailed logging when the updater fails.
Added check to make sure PowerShell v5 is present when using clink update.
Added unicode.fromcodepage() and unicode.tocodepage() for UTF8 conversions. One of the cases where this can be useful is when handling redirected output from programs that product output using the current Active Code Page.

v1.3.26

Added unicode.iter(), unicode.isnormalized(), and unicode.normalize() for more precise UTF8 string manipulation.
The updater now includes an HTTP header to request no caching, in an effort to work around an issue on Win8.x.
The updater now updates the version number displayed in the "Apps & features" section of Settings in Windows (or "Add or Remove Programs" in Control Panel in older versions of Windows).
Fixed the directories.dupe_mode setting in clink set.
Fixed the remove-history command when trying to remove a history entry added by the add-history command that hasn't yet been saved.
Fixed the /D= flag in the setup program.
Fixed potential double-load of scripts in the profile or binaries directories, due to an issue while searching completions directories (regression introduced in v1.3.24).
Fixed potential infinite loop when merging an argmatcher with itself.
Fixed potential accidental resume of an orphaned coroutine.
Fixed potential double-reporting of coroutine errors when the lua.debug setting is enabled.
Internal maintenance to the coroutine management system.

v1.3.25

Fixed updater when %TEMP% contains spaces.
Fixed executable file detection to color device names (such as nul, aux, con, lpt1, and com1) as neither recognized nor unrecognized.
Fixed #304; hang when typing device names (such as aux, con, lpt1, and com1) (regression introduced in v1.3.23).
Fixed #303; downloading latest update doesn't work on Windows 8.x.

v1.3.24

Standardized the order in which completions directories are searched.
Fixed the second return value from clink.popuplist(), which was backwards by mistake.

v1.3.23

Automatically loads Lua completion scripts from completions directories. This allows you to optionally store completion scripts (argmatcher scripts) in a separate directory from your other Lua scripts, so that completion scripts are only loaded when needed. This can speed up Clink start time, if you have a large volume of argmatcher scripts. See Completion Directories for more information.
Fixed clink.oncommand() when redirection appears on the command line before the command name (e.g. >somefile command).
Fixed both parts of #300; unable to find latest release zip file (incomplete fix in v1.3.22 by mistake).

v1.3.22

When the lua.debug setting is enabled, any uncaught errors in coroutines are reported (and logged).
Fixed edge case that could cause Windows Terminal to temporarily stop responding mouse input.
Fixed #300; unable to find latest release zip file.

v1.3.21

Improved the auto-updater when there are multiple copies of Clink on a computer; it no longer needs to download the .zip update file multiple times.
Fixed mouse input when the console is scrolled.
Fixed #299; update shown even though up to date.

v1.3.20

Fixed potential crash in popup lists if there are only a few items (regression introduced in v1.3.18).
Fixed #296; on some computers closing CMD reports it's taking too long to close (the fix works around external issue).

v1.3.19

Added directories.dupe_mode setting that controls how duplicates are handled in the directory history list for the clink-popup-directories command.
Added Del to delete a directory entry in the clink-popup-directories command.
Fixed obscure intermittent problem with delayinit argmatchers.
Fixed Ctrl-C and Ctrl-Break in CMD built-in commands (regression introduced in v1.3.14).

v1.3.18

Added a built-in updater for Clink, which is enabled by default. When enabled, Clink reports when an update is available. Run clink update to apply the update.
Added clink-insert-suggested-line, clink-insert-suggested-word, clink-insert-suggested-full-word, and clink-accept-suggested-line commands (see #280).
Added optional timestamps in the history file. The new history.time_stamp and history.time_format settings control whether timestamps are saved and whether/how timestamps are shown.
Added cmd.altf4_exits setting to control whether Alt-F4 makes cmd.exe exit. This is so that when the terminal.raw_esc setting is enabled pressing EscEsc behaves the same as Alt-Ctrl-[ as expected, while still allowing Alt-F4 to work.
Added horizontal scrolling in the history popup list.
Added clink.onprovideline() so scripts can register a function to be called after onbeginedit but before any input is processed. The function can return a string to be executed as a command line, in which case the line editor is not invoked and the onendedit and onfilterinput events happen immediately (see #263).
Added rl.gethistorycount() and rl.gethistoryitems() to access the history items.
Added os.gettemppath() to get the system temporary directory.
Added io.sopen() to control sharing access when opening or creating a file.
Both io.open() and io.sopen() support the "x" file mode modifier (combined with "w" or "w+"), which makes the function fail if the file already exists.
Improved the what-is command to apply word wrapping to the command description.
Fixed generating matches from history (fromhistory=true) in argmatchers (regression introduced in v1.3.13).
Fixed executable file detection for file names that contain + characters.
Fixed some input keys accidentally handled by the OS sometimes (regression introduced in v1.3.6; original fix was introduced in v1.2.10).
Fixed timing conditions where other console programs could accidentally override Clink's mouse input mode.
Fixed left mouse click in popup lists when terminal.mouse_input is enabled.
Fixed alternate key bindings for copy (Ctrl-Ins) and paste (Shift-Ins).
Fixed description column alignment in clink.popuplist().
Fixed keyboard driver for Alt-Ctrl-[ when the terminal.raw_esc setting is enabled.
Fixed keyboard driver for Alt-Ctrl-] and Alt-Ctrl-</kbd>.

v1.3.17

Fixed coloring executable files in the input line (some file types weren't detected correctly, and missing files were considered executable if their extension had a file type association).
Fixed a potential crash when coloring executable files in the input line (regression introduced in v1.3.16).
Fixed #281; screen height detected incorrectly (regression introduced in v1.3.16).

v1.3.16

Added os.sleep().
Revised the Clink documentation to directly include the Readline documentation.
Fixed executable file detection for file extensions that point at Progids instead of having a shell command.
Fixed double help message from history command when invalid flags are used.
Fixed crash when file permissions block accessing the history file, and the history command reports an error message accordingly.
Fixed #262; changing the terminal width between prompts (while a different program is running) caused Readline to start displaying the input line incorrectly.

v1.3.15

Fixed #269; reverse video could get confused (regression introduced in v1.3, and incompletely fixed in v1.3.4).

v1.3.14

Ctrl+Break can now interrupt some operations, including match display and match generators and the os.globfiles() and os.globdirs() functions in Lua scripts.
Added os.issignaled() so Lua scripts can cooperatively interrupt themselves.
Improved responsiveness of completion commands when an async prompt filter is still running in the background (io.popen() and os.execute() are serialized in prompt filter coroutines, and are serialized separately in match generator coroutines, but are not serialized in other coroutines).
Fixed displaying pasted lines.
Fixed doskey aliases in pasted lines.
Fixed #268; crash when copy command prompts whether to overwrite a file (regression introduced in v1.3.13).

v1.3.13

Argmatchers can use :chaincommand() to treat the rest of the command line as another command.
- Added an argmatcher for cmd that uses :chaincommand().
- E.g. so that completion after cmd program can be parsed by an argmatcher for program instead of cmd.
Argmatchers can be more involved in parsing the command line, if they wish. See Responding to Arguments in Argmatchers for more information.
- A callback function can be assigned to an argument position by including onarg=your_callback_function in the table given to :addarg().
- The onarg callback and match functions receive an additional user_data parameter. When parsing begins, the user_data is an empty table, and your functions can set or get data from the table. Each time a flag or argument links to another argmatcher, the new argmatcher gets a separate new empty user_data table.
- The built-in cd and pushd argmatchers use this to influence match completion for the rest of the input line. E.g. pushd \foo & program Tab uses \foo as the current directory when generating possible completions.
Functions registered with clink.onfilterinput() may optionally return multiple lines in a table.
Fixed completions for words that contain ., such as clink set color.Tab (regression introduced in v1.3.11).
Fixed doskey macros that use echo off $T ....
Fixed input line coloring for a drive letter by itself.
Fixed input line coloring for a file that exists but is not executable.
Fixed obscure edge case with delayinit argmatchers and operate-and-get-next.
Fixed potentially inconsistent input line coloring when classifier:applycolor() is given an escape code that sets only the foreground or background color.

v1.3.12

Improved clink-select-complete to show inline descriptions as long as they don't require more than 9 rows to display the matches.
Added second argument to the delayinit function for an argmatcher.
Added argmatcher:setflagsanywhere() and argmatcher:setendofflags() to control where flags are recognized.
Added clink.getargmatcher() to find the argmatcher for a command name or command line (line_state).
Added os.resolvealias() to expand doskey alias(es) in a line of text.
Added clink.oncommand() to register a function to be called when a command is entered in the edit line.
Improved support for argmatcher non-flag argument values that end with =: now they can have a linked argmatcher, and input line coloring is applied correctly.
Fixed quotes during completion (regression introduced in v1.3.11).
Fixed cd /d dir argmatcher (regression introduced in v1.3.11).
Fixed input line coloring for "echo" and other CMD commands; quotes disqualify a word from being a CMD command.
Fixed redundant argmatcher delayinit for flags.
Various minor backward compatibility fixes.

v1.3.11

Updated the list of recognized CMD command names.
Better support for ( and ) when expanding doskey macros (e.g. now ( macro foo ) & ( macro bar ) works).
Fixed word break characters during completion. Only = ; had ever worked before, and now the normal CMD completion word break characters work (including , ! + ( and many others).
Fixed match display to not force a single column unless there are descriptions present.
Fixed backward compatibility for _argmatcher:add_arguments() and _argmatcher:set_arguments() (they were mistakenly adding all the arguments into the first argument position).
Fixed backward compatibility for merging argmatchers.
- Merging argmatchers works again. It is still a simple merge similar to v0.4.9, but it should be sufficient for common cases.
- Fixed some bugs in how Clink v0.4.9 merged argmatchers (the unit tests for merging fail in v0.4.9).
- Added support for some merging cases that weren't implemented yet in v0.4.9.
And other obscure minor backward compatibility fixes.

v1.3.10

An argmatcher can extend itself on the fly, when needed. For example, if it needs to parse arguments and flags from --help text, or if the available command arguments change based on the current directory, or etc. See Adaptive Argmatchers for more information.
Recognizes ^ and environment variables when coloring the command word, and when navigating by typing a directory name by itself.
Added input line coloring for the rem command.
Fixed memory corruption (regression introduced in v1.3.1).
Fixed input line coloring for clink set setting value & another command.
Fixed argmatcher input line coloring for matches using the { match="abc" } syntax.
Fixed finding an argmatcher after ( at the beginning of the line.
Fixed mouse clicks in clink-select-complete to insert the clicked match, in addition to highlighting it.
Fixed #252; md and rd should complete more than 1 argument.

v1.3.9

When argmatcher:addarg() is passed a table containing fromhistory=true then additional matches are generated by parsing the history file to find values for that argument slot from commands in the history file.
Added clink.reclassifyline() which triggers input line coloring and redisplays the input line. This is intended for use by a coroutine that has made changes that will affect input line coloring.
Added match_builder:isempty().
Added mouse horizontal wheel support in clink-select-complete.
Added back the _argmatcher:setflagprefix() function.
Loading Lua scripts now reports any syntax errors when the lua.debug setting is enabled.
Incorporate Lua 5.2.4 (minor patches to the Lua language).
Report a warning if the profile directory is configured to point at a file.
AutoRun is selected by default again in the installer (reverted change from v1.3.5).
The terminal.raw_esc setting now also address the same kind of problem with Alt+[ and Alt+Shift+O as with the Esc key.
Fixed when an argmatcher adds nested tables of matches using the { match="abc" } syntax, so that the nested matches are added recursively and properly suppress adding a space after argument matches that end with : or =.
Fixed when match_builder:addmatch() and match_builder:addmatches() add nested tables of matches using the { match="abc" } syntax, so that the nested matches are added recursively.
Fixed when match_builder:addmatch() and match_builder:addmatches() add an "arg" match type, so that they automatically suppress appending a space after matches that end with : or = (the behavior was documented, but did not work correctly).
Fixed remove-history so that it updates the history offset correctly and subsequent editing operations affect the correct undo list.
Fixed obscure issues in how certain key binding patterns were reported by clink-show-help and dump-functions.
Fixed how clink echo reports Ctrl+Backspace and Ctrl+Alt+Backspace.
Fixed #249; sending keystrokes from WScript does nothing for some keys.
Fixed #244; installer did not detect previous installation directory (regression introduced in v1.3.5; the fix takes effect on the next install after an install with the fix).

v1.3.8

Added terminal.mouse_modifier setting and %CLINK_MOUSE_MODIFIER% environment variable; these can override the modifier keys that activate Clink mouse input.
Added %CLINK_SETTINGS% environment variable; this can override the directory where the clink_settings file is located. This can be used to put it in a directory that syncs between computers, for example.
During clink-select-complete Ctrl+Home or Ctrl+End select the first or last match.
When argmatcher:addarg() is passed a table containing nosort=true then the matches are unsorted (displayed in the order listed in the table).
The .zip file now contains _default_settings and _default_inputrc so that they do not take effect unless manually renamed to remove the _ name prefix. This avoids changing the defaults unexpectedly.
Fixed mouse click+drag in the input line (it accidentally behaved like double click+drag).
Fixed the selection highlight width in clink-select-complete when some matches have descriptions but some do not.
Fixed argmatcher:addargunsorted() to turn off sort.
Fixed #239; crash when F7 and Del.

v1.3.7

Mouse click+drag now works.
Mouse click below clink-select-complete list expands the list instead of dismissing it.
Fixed responding to mouse clicks when the terminal's scrollback buffer is not empty (it only worked in Windows Terminal).
Fixed #237; installer does not maintain previously selected "Autorun when cmd.exe starts" (regression introduced in v1.3.5).

v1.3.6

Added terminal.mouse_input setting; the default is auto. auto lets mouse input work in ConEmu, or in the default Conhost terminal when Quick Edit mode is unchecked in the console Properties dialog. See the documentation for more information.
Added cua-select-word command that selects the word at the cursor.
Ctrl+X,Ctrl+Z with a numeric argument always includes registered Lua match generators, prompt filters, etc even when the lua.debug setting is off.
Fixed potential for a coroutine to have extra delays sometimes when continuing past the end of one edit line, and into the next edit line.
Fixed a potential busy loop when the command word is unrecognized.
Fixed Quick Edit mode in plain Conhost windows; it had always been disabled (I never noticed because I always configure console windows to disable it anyway).

v1.3.5

Raised default history.max_lines to 10000.
Added an optional default_inputrc file:
- It is loaded from the profile directory, or from the binaries directory.
- It uses the same format as the .inputrc file, and is loaded immediately before the .inputrc files.
- It has the effect of superseding built-in default values for Readline configuration variables and key bindings; any settings in the .inputrc supersede those in the default_inputrc file.
The installer has a new "Use enhanced default settings" option which installs default_settings and default_inputrc files to provide default values that activate more of the Clink enhancements (to give a more enhanced experience "out of the box").
The installer no longer defaults to installing AutoRun.
The installer no longer has an option to use versioned install directory; files are installed directly in the install directory.
Added clink.runcoroutineuntilcomplete() which allows a coroutine to keep running past the end of one edit line, and into the next edit line.
Fixed os.execute() return values when run in a coroutine (regression introduced in v1.3.2).
Fixed the selection color in clink-select-complete when colored-stats is off.
Fixed problems when displaying matches that exceed the screen width.
Fixed #231; installer fails sometimes when uncheck "Use versioned install directory".

v1.3.4

Pressing Del or Ctrl+D in a command history popup deletes the selected history entry.
Changed the default color for directory match completions to bright yellow (bright blue is hard to see).
Added an argmatcher for history.
Added an optional default_settings file:
- It is loaded from the profile directory, or from the binaries directory.
- It uses the same format as the clink_settings file, and the values in it supersede the built-in default values for settings.
- Settings are now saved if they are set (vs cleared by clink set setting.name clear), even if the set value matches the default value.
Minor performance improvement when calculating columns widths when match.fit_columns is enabled.
Fixed accidentally using only one column in clink-select-complete when there are 9 or fewer matches and none of them have description text (regression introduced in v1.3.3).
Fixed Shift+Right to accept the next full word of the suggestion without clearing the rest of the suggestion (regression introduced in v1.3.3).
Fixed terminal emulation for the reverse video escape codes (this also fixes the right border color of the selected item in popup lists).
Fixed buffer overrun in Readline yank-last-arg when the previous command ends in a backslash.
Fixed the Readline History library to not apply Unix style backslash escaping in CMD (e.g. in program subdir\ text there are 3 arguments; the \ is not an escaped space).
Fixed crash when displaying matches and match.fit_columns is enabled and the terminal width is greater than 150 characters.
Fixed potential busy loop during idle (until a key is pressed) in certain cases (regression introduced in v1.3.3).
Fixed the emulated terminal color conversions from 8-bit and 24-bit.
Fixed cursor style when using clink to start a new command window from inside a Windows Terminal window.
Fixed quirk when using Clink file completion to complete a directory name for clink --profile \foo\, so that the path doesn't end up malformed.
Fixed a memory leak.

v1.3.3

Match completion display calculates column widths to fit the most columns on the screen. Can be controlled by the match.fit_columns and match.limit_fitted_columns settings.
Match descriptions are right-justified when more than one column is displayed, to help more columns fit.
When multiple columns of matches are displayed with descriptions, the descriptions are bracketed with parentheses for readability and accessibility purposes.
F1 in clink-select-complete toggles between showing descriptions at the bottom vs with the matches.
Added match.substring setting that uses a substring search for completions if none are found with a prefix search.
Added color.executable and color.unrecognized settings. When set, these cause the command word (the first word) to be colored if it is recognized as an executable file, or is not recognized as a command, doskey macro, directory, argmatcher, or executable file. Lookups are asynchronous for optimum responsiveness while typing.
Argmatchers can hide certain flags (e.g. synonyms) by using argmatcher:hideflags().
Argmatchers can disable sorting matches by using argmatcher:addargunsorted() or argmatcher:addflagsunsorted().
Generators can disable sorting matches by using match_builder:setnosort().
Fixed duplicated closing quote in clink-select-complete.
Fixed display of non-directory matches that contain slashes, such as git branch names (regression introduced in v1.3.1).
Fixed match display filtering in clink-select-complete (regression introduced in v1.3.1).
Fixed the insert-comment command (regression introduced in v1.2.44).
Fixed sorting flag completions so that all - flags precede any -- flags.
Fixed a couple of memory leaks, and added memory tracking system to more easily catch leaks.
Various minor fixes in clink-select-complete.

v1.3.2

Added Shift+Space as a recognized key. By default it is bound to clink-shift-space, which invokes whatever is bound to the normal Space key, so that it continues to behave as before unless you specifically bind something else to the Shift+Space key.
Added clink-magic-suggest-space command which inserts the next full suggested word (if any) up to a space, and then inserts a space. Binding this to Shift+Space can be very handy.
Added cmd.admin_title_prefix setting that can replace the "Administrator: " console title prefix.
When loading settings, if there is no setting file yet then Clink looks for a default_settings file in the binaries directory and uses that to initalize the settings.
Added CLINK_TERM_VE and CLINK_TERM_VS environment variables that can be set to override the normal (insert mode) and enhanced (overwrite mode) cursor styles, respectively.
Various minor fixes to how the cursor style is updated; the visible bell now works in Windows Terminal.
When os.execute() is used in a coroutine, it automatically yields until complete.
Fixed async match generators (during autosuggest) to be allowed to finish, instead of getting canceled on every keystroke if they hadn't finished yet.
Fixed cursor blink, which was accidentally disabled (regression introduced in v1.2.44).
Fixed the win-cursor-forward command so it doesn't trigger generating a new suggestion if there isn't already one.

v1.3.1

Added autosuggest.async setting (on by default) that lets suggestions generate matches asynchronously to stay responsive while typing.
Added match.max_rows setting that limits the number of rows clink-select-complete can use.
Added match.preview_rows setting that makes clink-select-complete show the specified number of rows of matches as a preview, and expands to show the full set of matches when the selection moves past the preview rows (similar to completion in the fish shell).
Added color.comment_row setting that chooses the color for the comment row in clink-select-complete. The comment row shows the "and N more matches" or "rows X to Y of Z" messages.
Changed arrow keys in clink-select-complete to wrap on both horizontal and vertical edges (similar to the fish shell).
Changed arrow keys in clink-select-complete at the beginning and end of the list to wrap to the other end based on the menu-complete-wraparound config variable.
Match generators can now specify an append character (or suppress appending) on a per-match basis.
The clink-diagnostics command lists prompt filters, generators, classifiers, and suggesters when a numeric argument is given (e.g. Alt+1 then Ctrl+X,Ctrl+Z).
The os.globdirs() and os.globfiles() functions now automatically yield periodically if used inside a coroutine.
The io.popen() function now automatically yields periodically if used in read mode (the default) inside a coroutine.
The io.popenyield() function now automatically falls back to io.popen() if used outside a coroutine.
Fixed input line coloring to operate on only the input line, not including the suggestion.
Fixed display when typing to filter clink-select-complete (regression introduced in v1.2.49).
Fixed display of clink-select-complete when the current match changes the number of visible lines in the edit buffer.
Fixed displaying matches when only a drive letter is entered.
Fixed #216; Long escaped URLs do not display correctly in a prompt.

v1.3

Added back mark-modified-lines support (was removed in v1.2.36).
Added rl.ismodifiedline() function so prompt filters can show a modified line indicator if they wish.
Added autosuggest.original_case setting (on by default) that controls whether parts of the line are updated to use the suggestion's original capitalization, or to keep the typed capitalization.
Added terminal.east_asian_ambiguous setting that controls how the width is determined for the East Asian Ambiguous range of characters (which includes the lambda character). This may help with working around display issues in some terminal hosts.
Added help descriptions for many vi mode commands.
Improved relevance of completion suggestions by suppressing them when the word at the cursor is empty.
The :suggest() function on suggesters can now return a suggestion string and an offset where the suggestion begins in the input line.
Fixed a limitation in Readline so that completion-prefix-display-length and colored-completion-prefix can coexist.
Fixed when temp files from io.popenyield() get deleted. They were lingering until Lua garbage collection, but they can be deleted almost immediately.
Fixed the order of initialization: first the Readline .inputrc config file is loaded, and then Lua scripts are loaded. This enables Lua scripts to reliably override Readline config variables if they wish (for example so a prompt filter can clear emacs-mode-string and print its own keymap indicator as part of the prompt).
Fixed transient prompt to not show keymap mode strings or the modified line mark.
Fixed vi mode key bindings that can accept suggestions.
Fixed missing vi-undo command; it was pre-bound to some keys but could not be bound to any other keys.
Fixed the "show help" commands when listing unbound commands: unbound vi mode commands should not be listed in emacs mode because the vi mode commands are only meant to be used in vi mode, and are not meant to be bound to custom keys.
Fixed memory leak in suggestions.

v1.2.50

Added rl.insertmode() function to get or set whether insert mode is active.
Added clink.onaftercommand() so scripts can register a function to be called after every input command (key binding).
Added additional failure logging during clink inject.

v1.2.49

Added cua-previous-screen-line and cua-next-screen-line, bound to Shift+Up and Shift+Down, to extend the text selection up/down by one screen line.
Updated match generator for clink set autosuggest.strategy to list the available suggestion generators.
The clink-show-help and clink-popup-show-help commands can include commands that aren't bound to any key, when the numeric argument is 4 (e.g. Alt+4 then Alt+H).
The rl.getkeybindings() function takes an optional mode argument to control sorting and whether to include commands that aren't bound to any key.
Generating suggestions skips generating match completions when the current word looks like a UNC path. This avoids pauses while typing that would otherwise occur when accessing networked drives.
Fixed Alt+Right so it accepts the next word of the suggestion, just like Ctrl+Right does.
Fixed the clink-paste command so it sets the mark to the cursor point prior to pasting.
Fixed when history.dupe_mode is "erase_prev" and history.shared starts true but changes to false; subsequent commands were not added to the history properly anymore in that session (regression introduced in v1.1.0).
Fixed #210; clink-select-complete drawing bug with RPROMPT.

v1.2.48

Ctrl+Right now inserts the next word of the suggestion the same way it would move to the next word, and Shift+Right inserts the next full word of the suggestion up to a space.
Keys like Home/End, Shift+Left/Right, and Ctrl+Left/Right work in VI mode.
Fixed input line coloring glitch when color settings use the sgr syntax.

v1.2.47

Added autosuggestions similar to the Fish shell.
- Turn on by running clink set autosuggest.enable true. See the autosuggest.enable and autosuggest.strategy Clink settings for details.
- Added clink.suggester() function to create new suggestion generators that can be used in the autosuggest.strategy setting.
The clink-diagnostics command also lists match generators registered by clink.generator().
Fixed the color when the horizontal-scroll-mode config variable is on.
Fixed the transient prompt when using Help commands.
Fixed the clink autorun commands when paths contain Chinese characters and the system code page isn't UTF8.
Fixed #209; clink-popup-show-help command fails.
Fixed #208; orphaned symlinks are colored wrong.
Fixed #203; unable to inject when Clink binary directory contains Chinese characters (regression introduced in v1.0.0).

v1.2.46

Added a magic-space command that performs history expansion on the text before the cursor point and then inserts a space. Note: this is slightly different than one in bash, which performs history expansion on the whole line and can end up inserting the space in a wrong spot.
Added rl.getbinding() and rl.setbinding() functions to query or override key bindings.
Added a clink.refilterprompt() function to invoke prompt filtering on demand.
The clink-popup-directories command is now bound by default to Ctrl+Alt+PgUp.
The clink-select-complete command is now bound by default to Ctrl+Space.
Fixed the clink-popup-history command so incremental search works again (regression introduced in v1.2.36).
Fixed messages sometimes not being erased when finished, e.g. when using Alt+digits (regression introduced in v1.1.11).
Fixed potential for prompt to redraw incorrectly after showing help when the prompt.transient setting is enabled.
Fixed settings defined by Lua scripts so that the Lua scripts can reliably see the current values even while the Lua scripts are being loaded or reloaded.

v1.2.45

Clarified description of the match.wild Clink setting.
Fixed #196; installer checkboxes not working properly.

v1.2.44

Fixed clink.ondisplaymatches() so it receives the right match strings (regression introduced in v1.2.39).
Fixed #194; argmatcher not found when command name contains a dash (regression introduced in v1.1.5).
Fixed #176; use current installation dir when upgrading clink. Now the installer remembers the chosen installation directory and defaults to the same place when installing an upgrade (all of the checkbox states are remembered, in fact).
Fixed #171; have a way to override install directory. Now the installer has a checkbox whether to install to a versioned directory (recommended). Unchecking the box installs program files to a bin subdirectory, instead of the usual versioned subdirectory.

v1.2.43

Fixed lingering issues with non-ASCII characters in path names in Clink (follows up on the preceding fixes for non-ASCII user name characters).

v1.2.42

Fixed potential for history file to get corrupted during compacting, if multiple Clink instances are running concurrently.
Fixed clink inject when the user account name contains non-ASCII characters (regression introduced in v1.0.0).
Fixed #193; consider removing the 50K history limit: The history.max_lines Clink setting once again supports 0 to mean unlimited. Note that as the history file grows larger, it takes longer to load. If the size becomes a problem, you can use clink history compact <n> to prune the history file to N items as well as compacting it (removing deleted items).
Fixed #192; completing ~ by itself does nothing: Completing ~ by itself now inserts the %USERPROFILE% directory. This is different than bash, because on Windows it doesn't make sense for ~ by itself to complete other user accounts. This is a convenient way to expand tilde into a path that Windows understands.
Fixed #191; cd /d - isn't supported: The cd - feature now supports cd /d - as well. It also supports cd - even if there is a doskey macro defined for cd.

v1.2.41

Fixed #187 differently: doskey.enhanced is true by default again, but if a macro contains $* or $1...$9 tags within quotes then | and & symbols are part of the arguments, not command separators (and expansion stops after that macro).
Fixed compatibility when doskey.enhanced is false; alias|whatever should not expand alias because there is no space after it.
Fixed doskey expansion when >& redirection symbol is present; command >& alias should not attempt to expand alias because it's a redirection file name, not a command.

v1.2.40

Fixed display quirks when an empty display or description string is provided by a match generator.
Fixed #187; the doskey.enhanced setting interferes with some macros (regression introduced in v1.0.0). The setting is now false by default, because of the incompatibilities it can cause.

v1.2.39

Fixed regression in match display filtering when listing possible completions (regression introduced in v1.2.38).
Fixed display quirks in the clink-select-complete command when descriptions are at the bottom.

v1.2.38

Enhancements for match descriptions (which are displayed when listing possible completions):
- Argmatchers can provide description strings for flags and/or args (e.g. "Verbose output" for -v, or "Do nothing" for -n, etc).
- Argmatchers can also provide argument info strings for flags and/or args. These are hint strings, and not part of the completion match itself. E.g. "linenum" for --line, which gets displayed as "--line linenum" when listing possible completions, but only "--line" is inserted.
- Match generators can provide display and description strings when adding matches (match_builder:addmatch() and match_builder:addmatches()) -- it is no longer necessary to use clink.ondisplaymatches().
- The clink-select-complete command now shows match descriptions in a single line at the bottom (instead of in a second column) when there are more than 9 matches.
- Added color.arginfo Clink setting for the arguments for a flag or argument when listing possible completions.
- Added color.description Clink setting for the default match description color when listing possible completions.
- Truncate descriptions when a line will wrap (or has wrapped) when listing possible completions.
Command separators (&, |) and redirection symbols (<, >, >&) are colored in the input line, using colors from the new color.cmdsep and color.cmdredir Clink settings.
Fixed Backspace in clink-select-complete; it had sometimes missed expanding the set of matches accordingly.
Fixed the clink-popup-history command to respect the search-ignore-case setting.
Fixed :nofiles() to dead-end an argmatcher (regression introduced in v1.0.0).
Fixed clink.ondisplaymatches() and clink.onfiltermatches() when there's only 1 match.
Fixed incremental find, find next, and find previous in console text popup lists.
Fixed backward compatibility for the old matching filtering API.
Fixed several other minor issues with match display filtering.
Fixed intermittent incorrect match generation for /flag: or /flag= flags.
Fixed duplicate removal with deprecated match generators.
Fixed when nested deprecated argmatchers are exhausted (regression introduced in v1.2.36).
Fixed deprecated match generators to not infer whether matches are filenames, to match the behavior of the v0.4.9 API.
Fixed how match.wild works with deprecated match generators; e.g. arg completions for z.lua weren't working (regression introduced in v1.1.5).
Fixed argmatcher for clink --profile so it produces directory matches.
Fixed %CLINK_RPROMPT% alignment when color.prompt is set.

v1.2.37

Fixed #180; rl.collapsetilde() behaves erratically.
Fixed #179; incorrect handling for certain keys on some keyboard layouts.
Fixed #178; OneDrive folders mistakenly show up as symlinks.
Fixed #177; be silent about autorun injection into TCC.

v1.2.36

Added win-history-list command bound to F7 by default. This shows the history list, and executes the selected history entry.
Changed all of the popup list commands to show popups using console text rather than GUI windows.
- Added a color.popup Clink setting for the popup colors. If not set, the console's popup colors are used.
- Added a color.popup_desc Clink setting for the popup colors for the description column(s). If not set, a color is chosen to complement the console's popup colors.
- Added a clink.gui_popups Clink setting that can be set to use GUI popup windows as before (the color.popup settings have no effect on GUI popup windows).
Key bindings now support Enter plus combinations of the Ctrl, Shift, or Alt modifier keys.
Added more backward compatibility shims.
Fixed the clink-select-complete command when print-completions-horizontally is on (and also minor issues when it is off).
Fixed the clink-select-complete command when a Lua script has used rl.setmatches() to provide a custom list of matches.
Fixed the clink-menu-complete-numbers family of commands (regression introduced in v1.2.32).
Fixed a situation where the scrolling keys could stop working (regression introduced in v1.2.24).
Fixed flags at the end of a linked parser, and fixed args at the end of two or more nested linked parsers (regression introduced in v1.0.0).
Fixed #172; add a choice in the installer to not add Start menu shortcuts.
Fixed #129; Bug completing files with - or _ characters (regression introduced in v1.0.0).

v1.2.35

Added rl_buffer:getanchor() to get the text selection anchor (there is no set function; use rl.invokecommand() to invoke commands to set/extend the selection if needed).
Reverted back to using IAT hooking (see issue #169).
Fixed CUA selection commands invoked by rl.invokecommand().
Fixed #170; directory symlink completion is truncated when mark-directories is off in the .inputrc file.
Fixed #169; incompatibility between AutoHotkey, AnsiCon, and Clink when all three are used in CMD's AutoRun regkey (regression introduced in v1.2.33).

v1.2.34

Changed "luafunc:" macro functions to receive the line_state as a second argument.
Fixed Right when clink.default_bindings is windows.
Fixed exec.files setting so completion works when a path is specified (e.g. subdir\foo) (regression introduced in v1.2.33).
Fixed #158; crash when a keyboard macro contains \015 (regression introduced in v1.0.0).

v1.2.33

Rewrote how Clink hooks APIs in CMD.EXE; it no longer uses any IAT hooking, and exclusively uses Detours.
Added clink.default_bindings Clink setting to choose between bash or windows default key bindings. bash key bindings are still the default, for compatibility with existing Clink installations.
Added exec.aliases, exec.commands, and exec.files Clink settings to further customize how matches are generated for the first word when the exec.enable Clink setting is enabled.
Small performance optimization in the hooked WriteConsoleW() system API.
Added logging for rare error case during inject.
Added default key bindings for F1 through F9 that mimic the default Windows console function key inputs.
Added clink-selectall-conhost command that mimics the default Windows console Select All command.
Fixed clink-select-complete to remove duplicate matches if generators try to add duplicate matches.
Fixed script error when %PATH% is not set and exec.enable and exec.path are both enabled.
Fixed some quirks when using the quoted-insert command.

v1.2.32

Added rl_buffer:setargument() function for a "luafunc:" macro to be able to set Readline's numeric argument.
Added os.getclipboardtext() and os.setclipboardtext() functions.
Added extra defense against antivirus interference (if it interferes when Clink inspects the target process, but permits Clink to inject into the target process).
Fixed cooperation between "luafunc:" macros and CUA selection commands (e.g. Shift+End).
Fixed rl_buffer:getcursor() and the return value from rl_buffer:setcursor(); both returned one less than the actual cursor position.
Fixed #162; clink completion shows script error (regression introduced in v1.2.31).

v1.2.31

Added clink uninstallscripts --all to clear all script paths installed by clink installscripts.
Added os.touch() function to set the access and modified times for a file.
Added more fields in os.globdirs() and os.globfiles() when extrainfo is requested.
Potential Breaking Change: Fixed os.globdirs() and os.globfiles() to only return extra info when actually requested (regression introduced in v1.1.8).
- This unfortunately changes the scheme and may break some scripts if they requested no extra info, but used the extra info anyway.
Fixed crash in clink-select-complete when a match display filter returns nil.
Fixed ondisplaymatches() which was receiving one fewer matches than it should (related to #124).
Fixed ondisplaymatches() which was not using the word break info correctly (from generators' :getwordbreakinfo() functions).
Fixed word_classifications:applycolor(); the input line didn't necessarily refresh correctly after a custom classifier applied custom colors.
Fixed potential stray inaccurate colorations when coloring the input for clink set color.something some_value.
Fixed #161; clink installscripts garbles previously-installed script paths when installing a new one.
Fixed #155; settings.set() doesn't update the settings file.

v1.2.30

Replaced the built-in Lua implementation of os.clock() so it doesn't stop working after the program has been running for more than 24 days (which caused asynchronous prompt filtering to stop working). As a side effect, the new os.clock() has microsecond precision instead of millisecond precision.
Fixed coroutine throttling. It was meant to prevent running more than once per 5 seconds, but accidentally forced running every 5 seconds, even if the coroutine was registered to run less often.

v1.2.29

Added prompt.transient Clink setting which can collapse prior prompts to a condensed form. The new %CLINK_TRANSIENT_PROMPT% and %CLINK_TRANSIENT_RPROMPT% environment variables supply the initial prompt strings, and prompt filters can define :transientfilter() and :transientrightfilter() functions to filter the transient prompt.
Added clink.logo Clink setting to globally control what startup logo is shown (full copyright logo by default, or a short version logo, or no startup logo).
Added console.readinput() function which waits for one key input, and returns the key sequence string for the key.
Added clink.reload() function which reloads Lua scripts and the Readline config file at the next prompt.
Added logging for more possible failure points while injecting Clink into the host process.
Added default key bindings for Ctrl+Up and Ctrl+Down to scroll the screen one line, like conhost normally does.
Now clink set cl* lists all settings that begin with cl (the star wildcard is only supported at the end of the string).
Documentation includes a link to the new clink-flex-prompt.
Fixed the Lua debugger to support printing UTF8 text, and to escape string variable contents to avoid escape code side effects.
Fixed #154; crash when settings.set("some_setting", false) is used.
Fixed #153; ESC key problem. Clink migrated the old esc_clears_line setting backwards, causing Esc to behave opposite from what was expected.
Fixed #152; LUA debugger breaks on the wrong line, and fails to execute expressions.

v1.2.28

Added rl.getpromptinfo() function.
Fixed loading .inputrc so that only one is loaded (regression introduced in v1.0.0a0 by the fix for mridgers #258). If similar behavior is still desired, consider using the $include directive in the Readline init file, to load additional files.
Fixed clink-select-complete to respect when mark-directories in .inputrc file is off.
Fixed crash in console.findline() when no attributes are passed. Callers using v1.2.27 and earlier can work around the crash by passing {} for attributes.
Fixed an off-by-1 bug in console.scroll("absolute", top). This will fix edge case malfunctions in some callers, but some callers could experience this as a breaking change.

v1.2.27

The cmd.get_errorlevel Clink setting is now enabled by default.
Clink now expands $ codes in %CLINK_RPROMPT% before running prompt filters.
Fixed parsing 2>&1 style redirection symbols, so the & doesn't get treated as a command separator.
Fixed argmatchers to generate file matches for redirection arguments; app.exe > should generate file matches for the > symbol, not matches for the app argmatcher's first argument.

v1.2.26

Fixed input line coloring for doskey aliases that don't have an argmatcher (regression introduced in v1.2.16).
Fixed Space during clink-select-complete when there were already opening and closing quotes present.
Fixed redrawing multiple lines of input after certain commands such as clink-show-help Alt+H (regression introduced in v1.1.20).
Fixed the completion-auto-query-items config variable to account for multiple lines of input, if present.
Fixed potential race condition if multiple Clink instances try to get the last errorlevel at the same time.

v1.2.25

Added cua-select-all command to select the entire input line.
Added edit-and-execute-command command to invoke an editor on the current input line and then execute the results (Ctrl+X,Ctrl+E). This attempts to invoke %VISUAL%, %EDITOR%, or notepad.exe as the editor, in that order.
Added some new expansion commands:
- clink-expand-history performs history expansion on the current input line (Alt+^).
- clink-expand-history-and-alias performs history and doskey alias expansion on the current input line.
- clink-expand-line performs history, doskey alias, and environment variable expansion on the current input line (Ctrl+Alt+E).
Added some new completion commands:
- glob-complete-word performs wildcard completion on the text before the cursor point, with a * implicitly appended (Alt+G).
- glob-expand-word inserts all the wildcard completions that glob-list-expansions would list (Ctrl+X,*).
- glob-list-expansions lists the possible wildcard completions of the text before the cursor point (Ctrl+X,g).
Added some command name synonyms for increased .inputrc file portability with bash:
- alias-expand-line is a synonym for clink-expand-doskey-alias.
- history-expand-line is a synonym for clink-expand-history.
- history-and-alias-expand-line is a synonym for clink-expand-history-and-alias.
- insert-last-argument is a synonym for yank-last-arg.
- shell-expand-line is a synonym for clink-expand-line.
Added a match.expand_envvars Clink setting to expand environment variables in a word before performing completion (for mridgers #476).
Changed the match.wild Clink setting to apply to all completion commands.
Changed default key binding Ctrl+Alt+E to the clink-expand-line command (not the key binding expands everything, instead of only the env var at the cursor).
Removed default key binding Alt+Shift+H for the clink-show-help-raw command (it has only niche usefulness).
Removed unintended VI mode key binding Alt+Ctrl+H.
Fixed Ctrl+Shift+2 and Ctrl+Shift+6 (regression introduced in v1.1.39).
Fixed More? continuation prompt when pasting multiple lines.
Fixed /flag: and /flag= handling quirks, especially when trying to complete an environment variable in /flag:%env.
Fixed quirks about environment variable expansion in the clink-expand-env-var command and the os.expandenv() function.

v1.2.24

Added support for %CLINK_RPROMPT% to show a right side prompt, and for prompt filters to define a :rightfilter() function to filter the right side prompt.
Fixed clink-select-complete to not append a space after a flag that ends with : or = (e.g. /x:).

v1.2.23

Fixed PgUp and PgDn in the clink-select-complete command, under certain conditions where they don't navigate in the intended manner.
Cosmetic change: better key names for Enter vs Ctrl+M, and Alt+Bkspc vs Alt+Ctrl+H, depending on the terminal.differentiate_keys setting.

v1.2.22

Added clink-what-is command bound by default to Alt+?, which shows the key binding for the next key sequence that is input.
Added rl.getargument() function to get the accumulated Readline numeric argument, if any. For use in "luafunc:" macros.
The clink-show-help command now categorizes key bindings and shows a description for the commands. Using a numeric argument can control whether categorization and descriptions are used.
Fixed invoking clink-select-complete while it is already active, so that it doesn't lose quotes around the current match if it has quotes.
Fixed clink-show-help to list "Enter" instead of "C-m" for the Enter key. Otherwise there's no way to differentiate between Enter and Ctrl+M when the terminal.differentiate_keys setting is enabled.
Fixed the insert-comment command, which accidentally fell back to inserting # after the first prompt (that's what bash inserts, and shouldn't be used in Clink).
Fixed the dump-functions command, which accidentally didn't list UTF8 key sequences correctly.

v1.2.21

Fixed backwards exit codes from clink autorun commands.
Fixed alert message text on startup when debug.log_terminal is set to true.
Fixed #143; crash on start when terminal.raw_esc is true (regression introduced in v1.2.19).

v1.2.20

Added os.debugprint() function to print debug text via the OS OutputDebugString() API.
Enabled match completion coloring even when using match display filtering.
Fixed input of slash and backslash in non-directory completions when using the clink-select-complete command.
Fixed match display filtering in the clink-select-complete command.
Fixed match display filtering in the clink-popup-complete command.
Fixed quirk from Readline where it sometimes displays one fewer columns of matches than actually fit on the screen.

v1.2.19

Added clink-select-complete command which shows an interactive list of possible completions.
Added terminal emulation for CGI G, CSI s, and CSI u sequences.
Fixed column alignment for match display filtering when some characters take more than one cell to display.

v1.2.18

Added completions for clink installscripts and clink uninstallscripts.
Added support for Readline's coloring and marking of symlinks.
Fixed clink installscripts --help.
Fixed clink-popup-directories for directories with spaces.

v1.2.17

Added clink-popup-show-help command to show popup list with searchable list of key bindings and invoke the selected key binding.
Added clink.popuplist() function to show a popup list. Only usable from inside a "luafunc:" key binding.
Incremental search in the popup list window now centers the found item so items above and below it are visible.
Fixed potential internal error when a doskey alias starts with $ (regression introduced in v1.2.16).
Fixed potential infinite loop when the cmd.auto_answer setting is enabled but an error occurs while retrieving a language string (might be related to #137).

v1.2.16

Breaking Change: The clink.onendedit() Lua event has been split into two separate events:
- clink.onendedit() registers a function to be called when the edit prompt ends.
- clink.onfilterinput() registers a function to be called after the edit prompt ends (and after the onendedit event is sent), and the function can replace the input text.
Added rl.getkeybindings() function to get a table containing key bindings. The bindings can be invoked via rl.invokecommand(). For example, a "luafunc:" macro could use this to get key bindings, show an interactive list, and then invoke the selected key binding.
Fixed #134; print() can stop working. Issue #93 can potentially happen any time redirection is used, so the fix must be applied repeatedly (not just after Clink injection).
Fixed #119; reuse registered parsers for doskey macros.

v1.2.15

Fixed #132; multiline prompt gets overwritten when resizing the terminal width (regression introduced in v1.2.14).

v1.2.14

Automatically runs clink_start.cmd from the binaries directory and/or the profile directory when Clink is injected.
Clink is able to retrieve the last exit code for use by Lua scripts.
- The new cmd.get_errorlevel setting is off by default, but when enabled it retrieves the last exit code from CMD before running Lua scripts.
- The new os.geterrorlevel() function gets the last exit code (or 0 if the setting is off).
- It works by running a hidden command line between each interactive prompt (as if you typed echo %errorlevel% yourself every second command you type). If you experience problems with this, turn it off.
Improved refreshing the input line when resizing the terminal window. It's better than before, but there's no way to make it work perfectly because Windows can resize the terminal further while a program is already trying to respond to the terminal having been resized previously.
Fixed #130; doskey alias completions stop working when there are many aliases.

v1.2.13

Added support for linking a parser to flags ending with : or =; now completion works for the flag's argument.

v1.2.12

Improved diagnostic output for coroutines (Ctrl-X,Ctrl+Z), plus more diagnostic info when the lua.debug setting is enabled.
Fixed potential for a script error when a coroutine gets skipped due to a new prompt starting.

v1.2.11

Added clink.print() function which behaves like print() but with support for ANSI escape codes (and terminal emulation), and also a NONL special argument that suppresses the usual newline at the end of the output.
Expanded the sample code for async prompt filtering to clarify some things.
Fixed #126; allow Esc to input literal escape character.
- The new terminal.raw_esc setting controls how Esc input works.
- Added migration for the old esc_clears_line setting.

v1.2.10

Added asynchronous prompt filtering -- scripts can use this to do work in the background (e.g. git status) and refresh the prompt when finished.
- Added clink.promptcoroutine() function to allow a prompt filter to do some work in the background.
- Added io.popenyield() function to allow a coroutine to yield until the command's complete output is ready.
- Added prompt.async setting that can disable asynchronous prompt filtering if preferred.
Log error codes for failures during clink inject.
Clarified help text for clink autorun (per #122).
Documentation clarifications and reorganization.
Fixed clink and history aliases getting lost after exiting a nested Clink instance.
Fixed some input keys accidentally handled by the OS after certain Lua code is run.
Fixed #124; onfiltermatches() receives one fewer matches than it should.
Fixed #123; Failed to inject (Host validation failed).
Fixed #117; Setup causes "System Error".

v1.2.9

Added detection for possible antivirus interference when injecting Clink.
Ignore duplicate scripts paths when loading scripts.
Fixed #118; inputrc is not read from state directory (regression introduced in v1.0.0).

v1.2.8

Fixed ...\ or .../ to change directories (path separator after several dots).
Fixed /dirname/ to change directories (forward slashes when a directory is the only thing in the input line).
Fixed #114; "Clink already loaded in process" error when autorun is installed for both Current User and All Users.
Fixed #113; forward slash translation didn't work with the cd command.

v1.2.7

Fixed #113; clink.slash_translation() had been removed (regression introduced in v1.0.0).
- The new match.translate_slashes setting controls the default behavior for slash translation for completion matches.
- The new clink.translateslashes() API can override slash translation for completion matches (and clink.slash_translation() is supported for backward compatibility).

v1.2.6

Fixed tilde expansion for directory by itself; now ~\ can change the working directory to the ~ directory.
Fixed pagination when displaying completions that take more than 1 line to display.
Fixed inserting directory match completions when a Lua script didn't include a trailing path separator in the directory match.
Fixed #111; .. completion is different from bash (regression introduced in v1.0.0).

v1.2.5

Added os.expandenv() function to expand environment variables in a string.
Added console.cellcount() function to count the cells a string will use when displayed.
Added console.plaintext() function to remove ANSI escape codes from a string.
Clink now sets %=clink.bin% that points to the Clink binaries directory. This can be particularly useful for a portable installation of Clink so that scripts can find the Clink binaries directory and construct relative paths to other nearby files.
Clean up column alignment in --help texts.
Fixed history.sticky_search with anchored history search.
Fixed clink inject --profile to use correct log file name while initially injecting.
Fixed Clink autorun to be more compatible with Cmder (Cmder #2536).

v1.2.4

Added support for Shift+Arrows to select text and typing to replace selected text.
Added optional argument to word_classifications:classifyword() and word_classifications:applycolor() to allow only applying color where another color hasn't yet been applied.
Fixed first Up after reusing a history line so that it gets the reused history line, rather than getting the previous history line.
Fixed add-history command to not add blank lines to history.
Fixed rl.setmatches() (regression introduced in v1.1.26).
Fixed input coloring for clink set and any color setting name (regression introduced in v1.2).
Fixed potential crash with clink history --session.
Fixed Ctrl+D when cmd.ctrld_exits is disabled; it didn't exit, but it did still discard the input line and start a new prompt.
Fixed #107; autorun reports inject failures (regression introduced in v1.2.3).
Fixed #106; history missing --bare option (regression introduced in v1.2.3).

v1.2.3

Added history.sticky_search setting: when enabled, reusing a history line does not add the reused line to the end of the history, and it leaves the history search position on the reused line so next/prev history can continue from there (e.g. replaying commands via Up several times then Enter, Down, Enter, etc).
Added failure reporting and logging when clink inject fails.
Added --unique flag for use with clink history compact --unique to remove duplicate entries from the history list.
The clink-popup-complete command now matches wildcards.
Restored the Ctrl+Alt+U key binding from v0.4.9 (moves the current working directory up one level).
Fixed searching for inputrc files to also search in the profile directory (regression introduced in v1.0.0).
Fixed incremental search in the History popup list to search in reverse order (bottom to top).
Fixed clink-popup-history to set the history search position like other history search commands do, so that it plays well with the history.sticky_search setting.

v1.2.2

Added %CLINK_HISTORY_LABEL% environment variable to use a different master history file (fixes #99).

v1.2.1

Added Troubleshooting Tips section in the documentation.
Added backward compatibility for clink set with v0.4.9. Old setting names and values are not documented, but are automatically mapped to the appropriate new setting(s). This was done so that suggestions in old web sites and posts can usually continue to work, to reduce confusion and support burden.
Fixed #97; VS2017 error C2039: 'min': is not a member of 'std'.
Fixed #96; wrong setting string (the name of a setting was accidentally truncated).
Fixed some slightly inaccurate/incomplete migration from old settings to new settings.

v1.2

First official release from chrisant996/clink fork.

v1.1.49

Added clink.classifier() to enable coloring the input line independently from argmatchers.
Added word_classifications:applycolor() to apply SGR escape codes anywhere in the input line.
Removed word_classifications:iswordclassified().
Fixed the Product Version string in the binary file version resources.

v1.1.48

Added clink.getansihost() function to get Clink's best guess who will process ANSI escape codes (can be useful for avoiding 256 bit and 24 bit color codes, for example).
Added detection for being hosted in ConsoleZ.
Fixed #20; set /p VAR="" shows the normal command prompt text instead of empty prompt text.

v1.1.47

Added default key binding for Ctrl+Space to invoke old-menu-complete, which is the most similar to CMD's standard Tab behavior.
Fixed search-ignore-case config variable to be on by default.

v1.1.46

Added rl.setvariable() to temporarily override the value of a Readline config variable.
The completion commands now also expand tilde by itself (~), in addition to tilde followed by a path separator (~\etc).
Fixed #94; setting history.save to False also disables interactive history in subsequent sessions.

v1.1.45

Fixed #93; stdout is sometimes broken by Cmder init.bat.

v1.1.44

Added clink.getsession().
Added %CLINK_NOAUTORUN% which overrides automatic inject when Clink is installed for autorun.
Fixed #92; clink-popup-history and similar commands not working with ConEmu and Cmder (regression introduced in v1.1.25).

v1.1.43

Added clink history --diag flag that prints diagnostic information while performing history operations.
Minor optimization in clink history when printing the full list of history items.
Fixed clink history compact so it actually performs compaction.

v1.1.42

Added clink history --bare flag to omit history item numbers.
Added several Lua functions:
- io.popenrw() is like io.popen(), but returns both a read file handle and a write file handle (see documentation for important usage warning).
- os.createtmpfile() creates a unique named temporary file, with control over the prefix and suffix and path.
- os.getfullpathname() to get the full path name for a file.
- os.getlongpathname() to get the long path name for a file.
- os.getshortpathname() to get the 8.3 short path name (if available) for a file.
Improved argument validation for Clink's Lua APIs. This could expose bugs in existing scripts, so there is also a lua.strict setting that can be disabled to revert back to loose argument validation.
Updated documentation.
Fixed clink history compact so that it forces compaction as intended.
Fixed completion for clink set so that filename completion works in string settings.
Fixed backwards return value from rl.invokecommand().
Fixed console input/output modes across "luafunc:" key bindings, in case the Lua functions spawn a process that alters the console mode without restoring it.

v1.1.41

Added terminal.adjust_cursor_style setting as a workaround to avoid interfering with the Windows 10 Cursor Shape console setting. There are several trade-offs, though.
Added rl_buffer:refreshline() function to redraw the input line, e.g. in case something has written over it.
Added os.getpid() function to get the process ID, intended mainly to help salt unique resource names.
Added clink.onfiltermatches() so scripts can register a callback function to run after Clink generates matches and before it displays them.

v1.1.40

Added a group of clink-complete-numbers commands that do completion for numbers from the console screen, bound to Ctrl+Alt+N by default.
Added rl.getlastcommand() function that returns the name of the last command invoked by key bindings.
Fixed sort order in Alt+H for the newly supported key bindings (that were added in v1.1.39).
Fixed Ctrl+Space (regression introduced in v1.1.39).
Fixed various Ctrl+Shift+whatever combinations (regression introduced in v1.1.39).
Fixed rl.setmatches() when the input line is not empty and clink.colorize_input is enabled.

v1.1.39

Added support for many more key bindings, such as Ctrl+Shift+Letter keys.
Added terminal.differentiate_keys setting that when enabled allows binding Ctrl + H or I or M or [ separately from Backspace, Tab, Return, or Escape.
Removed terminal.modify_other_keys setting and made it always enabled.
Changed terminal.use_altgr_substitute to be disabled by default so that Ctrl+Alt key bindings can work by default on keyboards with AltGr.
Changed output from clink echo so it's directly usable in the inputrc files.
Fixed terminal.use_altgr_substitute to only affect AltGr substitute key combinations (it had always broken the RightAlt key in general on other keyboard layouts).
Fixed a benign issue with the console input mode in clink echo.

v1.1.38

Fixed #84; added terminal.use_altgr_substitute setting.
Fixed #80; clink.log is not deleted when Cmder injects Clink.

v1.1.37

Fixed copy to clipboard (it never cleared the clipboard!).
Fixed #82; added two new clink.paste_crlf modes: ampersand replaces newlines with ampersands, and crlf pastes newlines as-is and executes any commands ending in a newline.
Fixed #69; space in the prompt disappears after enter echo: added support for CJK codepages.

v1.1.36

Fixed #79; Issue with United States - international keyboard layout (regression introduced in v1.1.0).
Fixed #78; crash when history file contains a line longer than 8192 characters (regression introduced in v1.1.2-alpha).

v1.1.35

Fixed when the mark-directories inputrc variable is off (regression introduced in v1.1.1-alpha).
Fixed Lua reading from stdin, especially in the Lua debugger (regression introduced in v1.1.25).
Fixed exponential cost performance bug in Readline when removing duplicate matches.

v1.1.34

Fixed copying to clipboard (CF_UNICODETEXT was put on the clipboard correctly, but CF_TEXT was empty and should have been omitted to let Windows automatically convert it from the Unicode text).

v1.1.33

Make the "replacing arglink" warning message a little more informative, and write a lua traceback to the Clink log file.
Fixed #77; with ConsoleZ scrolling does not always work.
Fixed #76; cannot cd up multiple directories normally.

v1.1.32

Added support for non-standard escape codes to set the window title or print environment variables. Depending on the terminal.emulation setting, the behavior is slightly different. When emulate Clink processes the escape codes. When native with ConEmu (and Clink) the escape codes are passed to ConEmu, except that Clink processes the environment variable codes in prompt strings. When native with other terminals, Clink preprocesses the title and environment variable escape codes in prompt strings, but passes the escape codes to the terminal outside of prompt strings.
Fixed #67; AutoRun interferes with Cmder.

v1.1.31

Fixed #74; clink gets confused by non-standard ConEmu escape codes.
Fixed #73; exec.space_prefix and other settings defined in Lua scripts don't take effect until second input line (regression introduced in v1.1.4).

v1.1.30

Fixed history compacting on x86 (regression introduced in v1.1.2-alpha).

v1.1.29

Added clink installscripts and clink uninstallscripts to make it easy for package managers like Scoop to install/uninstall script packages for use with Clink. The installed script paths are stored in the registry for the current user.
Fixed bold vs bright colors to more accurately follow generally accepted ANSI escape code conventions:
- Renamed dim to nobold for clarity (though dim is still recognized for backward compatibility).
- bold adds intensity to a non-intense color (e.g. cyan which is 36).
- nobold removes intensity added by bold (e.g. 1;36 becomes 36), but does not remove intensity from an explicit intense color (such as bright cyan which is 96).
Fixed support for --file= flags in argmatchers.
Fixed match display filtering on the first try for a word (regression introduced in v1.1.19).
Fixed the clink --profile flag (regression introduced in v1.1.10).
Fixed clink info to accurately report the script dirs (it didn't account for the clink.path setting correctly).

v1.1.28

Renamed the log.rl_terminal setting to debug.log_terminal; it has already been repeatedly very useful in multiple was since it was added, so it stays.
Fixed #70; ctrl+c not working (regression introduced in v1.1.25).

v1.1.27

Added color.argmatcher setting which, when set, is used to color a command name if it has an associated argmatcher (this supersedes color.cmd, color.doskey, and color.input). By default it's not set.
Added log.rl_terminal setting which logs all terminal input and output for Readline (this setting may be renamed or removed in the future).

v1.1.26

Added rl.invokecommand() which can invoke a Readline command from inside a "luafunc:" key binding.
Added rl.setmatches() which can override match completions from inside a "luafunc:" key binding.
Worked around UTF8 key binding problem with Readline which had been causing some meta key bindings (M-x, M-C-x, etc) to sometimes produce garbled key bindings and garbled entries in clink-show-help (Alt+H).
Fixed crash if "luafunc:" key binding macro refers to a symbol that doesn't exist.

v1.1.25

Added clink-find-conhost command that, when in a default (conhost) console window, is equivalent to picking "Find..." from the system menu.
Added clink-mark-conhost command that, when in a default (conhost) console window, is equivalent to picking "Mark" from the system menu.
clink-copy-word now copies the current word by default, but copies the nth word if a numeric argument is entered (see "Readline Arguments" in the Readline manual).
Fixed match display filtering to not exceed the screen width (regression introduced in v1.1.12).
Fixed multi-key sequences; in some cases it could get confused about whether an input key is part of a multi-key binding sequence (regression introduced in v1.1.1-alpha).
Fixed stray input processing by conhost (holding Ctrl+A or Ctrl+F or etc could accidentally trigger conhost's shortcut keys).
Fixed popup window location and size when using Windows Terminal.
Fixed input coloring after operate-and-get-next; also fixes brief flicker of incorrect coloring whenever the input line is modified.

v1.1.24

auto for terminal.emulation now uses native VT support on Windows 10 build 15063 and higher, unless the HKCU\Console\ForceV2 regkey is 0.
Special quote handling now enables "dir\"fi to complete to "dir\file". CMD simply strips quotes during completion, and now Clink behaves similarly.
Breaking Change: line:getword() and line:getendword() now strip quotes from the word. This should generally automagically make existing match generators work even with embedded quotes, but there's a chance that some match generator might need to be updated. This seems like a reasonable compromise, given the general benefit purchased by this breaking change.
os:globdirs() and os:globfile() strip quotes from the globpattern in order to behave more like CMD. Embedded quotes are nonsensical and the intended interpretation is clear, so the APIs now help out with that.
Fixed #66; crash when injecting into 32 bit cmd (regression introduced in v1.1.21).
Fixed #64; wrong cursor position when PROMPT contains BEL character.
Fixed #62; argmatchers should color -x:"foo" as a flag if -x: is a flag.
Fixed #61; argmatchers should not handle completion for text immediately following -flag:. Instead it always uses file completion. A custom generator can be used to override that behavior.
Fixed #60; completion fails with multiple slashes.
Fixed completion in some circumstances. Readline and Clink didn't always agree on where the word breaks were; now Clink always tells Readline where the word breaks are (so that completion, input colorization, and lua scripts can all work properly and consistently).
Fixed 256 color ANSI codes.

v1.1.23

Fixed #57; slashes not normalized in some cases.
Fixed #45; interaction between history.dupe_mode=erase_prev and history.shared=false.
Fixed menu-complete-wraparound when off and there's only 1 match.

v1.1.22

Added menu-complete-wraparound (on by default) that controls whether completion commands wrap around when cycling past an end (affects popup windows as well).
Fixed match completion getting stuck (regression introduced in v1.1.19).
Fixed active mark region so it gets deactivated appropriately (it wasn't hooked up fully for Readline's callback mode, which is the mode Clink uses).
Fixed clink-show-help (Alt+H) so it's able to list C-@ bindings.
Fixed inconsistent mark color.

v1.1.21

Added clink.oninject() so scripts can register a callback function to run when Clink is injected into CMD.
Added console.linehascolor() function that returns whether the specified line contains any of the specified colors.
Added console.findprevline() and console.findnextline() functions that can search backwards or forwards for text and/or colors in the screen buffer. Regular expressions may be used.
Fixed doskey alias parsing for match generators and input line coloring (Clink had been using slightly different parsing rules than CMD does).
Fixed the "-- More --" prompt while listing key bindings; Esc didn't quit, and unexpected keys weren't ignored.

v1.1.20

Now you can bind Lua functions to keys via "luafunc:" macros! Added new rl_buffer type that gets passed to the Lua function.
Added a group of console Lua APIs intended mainly for use by Lua function key bindings (e.g. console.scroll()).
Added string.equalsi() function that performs a case insensitive UTF8 comparison of two strings.
Added string.matchlen() function that compares two UTF8 strings and returns how many characters match at the beginning, or -1 if the entire strings match. It respects the match.ignore_case and match.ignore_accent settings.
Added path.toparent() function that adjust the input string by moving up one directory level.
Added clink.onendedit() so scripts can register a callback function to run when editing finishes (e.g. Enter is pressed). If desired, the function can even change the input text. This is very powerful, and should be used carefully.
Changed os.getbatterystatus() to return a table with the battery status details, rather than four separate return values.
Fixed the doskey.enhanced setting to not expand doskey aliases when preceded by a space. However, a doskey alias after a & or | command separator needs to be preceded by two spaces to avoid expanding it. That's so alias & alias expands both, and alias & alias expands neither; while the rules are more complicated to explain, they make more sense visually.
Fixed environment variable completion (regression introduced in v1.1.19).
Fixed Cmder startup (regression introduced in v1.1.17). Cmder expects to be able to replace Clink v0.4.9's clink.lua file, but there is no such thing anymore in newer versions of Clink. To be properly backwardly compatible with Clink v0.4.9 requires loading clink.lua (if it exists) from the first script directory listed by clink info, and ignoring clink.lua files in all other script directories.

v1.1.19

Improved responsiveness while typing: matches are collected only on demand, instead of always while typing. This makes it possible to always support match completion for UNC paths.
Fixed #50; Alt+H could warn about likely mistakes in key bindings.

v1.1.18

The input text now has context sensitive coloring based on the argmatchers. It's on by default and can be turned off with clink set clink.colorize_input false.
Updated the Readline library to 8.1.
Terminal emulation now supports the audible bell character.
Fixed #48; menu-complete gets stuck.
Fixed #47; Alt+D erases history instead of word.
Fixed #46; typing .. in subdirectory of root doesn't work.
Fixed restoring color after pager when showing help.
Fixed clink set match completions for color settings.

v1.1.17

Added os.getbatterystatus() function that gets battery status information much faster than launching wmic.
Fixed #44; Path completion doesn't work with cd /d.
Fixed loading scripts to ignore loading clink.lua, so that loading scripts behaves like Clink v0.4.9.

v1.1.16

Added match.ignore_accent setting (enabled by default) that ignores Latin alphabet diacriticals when completing matches (e.g. ä matches a, ı matches i, ł matches l, etc).
Fixed #42; history lines are split on special characters.
Fixed #41; Enable custom doskey handling of .. and -.
Fixed Readline bug inserting dir matches; \win_ foo (cursor at _) would become \Windows\\_ foo.
Fixed the quoted-insert command to insert just \x1b when ESC is pressed.

v1.1.15

Migrating settings now immediately writes a new settings file, instead of waiting until a setting is changed.
Added support to detect when running in Windows Terminal and use native terminal support (which enables things like Xterm 256 and 24-bit color support).
Added terminal emulation support for Xterm 256 and 24-bit color escape codes. Clink maps the specified color to the most similar color in the active 16 color palette (using the CIELAB color space). To get full support for 24-bit color, it's necessary to use ConEmu or Windows Terminal or a similar console host, or to set terminal.emulation to native (which isn't supported on some older Windows OS versions).
Allow doskey macros named .. or -, and also now doskey macros that resolve to .. or - or a directory name will work (just like if the macro text had been typed at the Clink prompt).
Fixed compatibility problem with various scripts getting the %HOME% environment variable. Now if it isn't set, then Clink synthesizes %HOME% from %HOMEDRIVE% and %HOMEPATH% or from %USERPROFILE%.
Fixed saving color settings to behave like other settings: only write a setting's value to the setting file if it differs from the default value.
Fixed the clink.print() Lua function so it also works during loading scripts and during prompt filtering.
Fixed the Readline input text display getting garbled if the filtered prompt includes Xterm's OSC window title code (\x1b]0;text\x07). Clink doesn't support that escape code, but at no longer garbles the input text if that escape code is present.

v1.1.14

Migrate settings and history from an old version of Clink, if present. This only happens if the new-version Clink settings or history files don't exist. (Deleting an existing new-version Clink settings or history file will cause migration to happen again.)
Added color.prompt setting for backward compatibility with Clink v0.4.x.

v1.1.13

Fixed clink.arg.register_parser backward compatibility.

v1.1.12

Added clink.ondisplaymatches() as a replacement for the deprecated clink.match_display_filter. The new API is able to support popup list windows as well.
Speculative possible fix for #35 Crash when clink on clink.bat.
Fixed #33; Tab autocomplete, auto-quoting paths doesn't seem to work as in Clink 0.4.9.

v1.1.11

Changed to load Lua scripts only once per session, unless forced to reload them. This enables backward compatibility for things like z.lua which has certain features that rely on Clink only loading scripts once per session.
Added clink.onbeginedit() so scripts can register a callback function to run each time the edit prompt is activated.
Added lua.reload_scripts setting to optionally force reloading Lua scripts each time the edit prompt is activated.
Added color.message setting for the Readline message area color (e.g. the search prompt message or digit argument prompt message, etc).
Fixed stray sticky = appended to completions after typing set and then typing a different command.

v1.1.10

Fixed #32; hooking ReadConsoleW on Windows 7.

v1.1.9

Added backward compatibility for clink.match_display_filter. The clink-completions/git.lua script uses it a lot, and that should all be working now.
settings.add adds a color setting when the type is string and the name starts with "color.".
settings.get now has an extra parameter to request the user friendly color name when getting a color setting.
Added clink.version_encoded variable with the Clink version number as MMmmmpppp (e.g. v1.1.9 is 10010009) to make it easy for scripts to check for feature availability.
The clink info command now shows Lua script paths as well.
Fixed backward compatibility for loading scripts from the profile directory (if clink.path isn't set, then load scripts from the DLL directory and the profile directory).
Fixed some color.input bleed through to other things (introduced in v1.1.5).
Fixed scroll commands (regression introduced by input line color in v1.1.5).
Fixed horizontally sorted match display and re-enabled the performance fix from v1.1.4.
Fixed wildcard evaluation with non-file and non-directory matches (e.g. a branch name origin/master accidentally didn't match or or *ma because of the /).
Fixed sort order of foo\ vs foo.bar\ when displaying matches or using the menu-complete family of commands.
Fixed potentially-missing trailing path separator when menu-complete completes a directory match (regression introduced by wildcard matching in v1.1.5).
Other obscure minor fixes.

v1.1.8

Fixed file match completions when an argmatcher only generates flag matches.
Fixed automatic inferring whether Readline should use filename completion and/or display rules (regression introduced by backward compatibility in v1.1.3-alpha).
Fixed backward compatibility for clink.find_files() and clink.find_dirs() (regression introduced by performance improvement in v1.1.7).
- Ignore extra arguments after the first one (the performance improvement in v1.1.7 revealed that some scripts call clink.find_files() with extra invalid arguments; e.g. clink-completions/modules/matchers.lua).
- Don't append a trailing path separator on directory names returned by these functions (the new os.globfiles() and os.globdirs() functions do, but the old clink.find_files() and clink.find_dirs() functions should not).
Fixed backward compatibility for coloring matches (regression introduced by backward compatibility changes in v1.1.4).

v1.1.7

Performance improvement when displaying matches: When enumerating files and dirs, the os.globfiles and os.globdirs functions have all the info about each file. Now they can return that info in a table. This frees the match display function from needing to do any further file system IO. The performance boost is noticeable.
Rewrote the color settings: the .fg and .bg sub-settings are gone, and the main setting now uses a more natural syntax (e.g. clink set color.input bright yellow or clink set color.modmark bright cyan on blue).
Added "cmd" match type for shell (CMD.EXE) command completions.
Added VT emulation for the reverse video SGR parameters.
Fixed tab completion for clink set setting, and also handle the new color setting syntax.
Fixed confusing behavior if multiple scripts try to add settings with the same name (now the first one succeeds and the rest report errors).

v1.1.6

Hooked up tilde completion in the cd, md, and rd command argmatchers.
Hooked up tilde completion with the exec.enable setting ("~\pro" matches "C:\Users\myusername\program.exe").
When terminal.emulation is auto, now it also detects ANSI{32|64}.DLL just like Clink 0.4.8 did.

v1.1.5

The menu-complete family of commands now support matching ? and * wildcards when the match.wild setting is enabled.
Added colour.input and colour.modmark settings for coloring Readline's input line.
Added clink.upper() Lua function, and both clink.lower() and clink.upper() are properly UTF8 aware now.
Added clink-copy-word command that copies the word at the cursor to the clipboard.
Added clink.promptfilter setting to control whether to filter the prompt with Lua scripts.
Renamed terminal.emulate setting to terminal.emulation.
Improved executable file extension logic to consistently use %PATHEXT% (and efficiently).
Improved file extension logic (e.g. "file.foo bar" has no extension because of the space).
Updated arg matcher for clink itself (was missing some flags).
Changed colour.hidden setting to not be set by default.
Fixed #28; Tab completion for "~" does not work.
Fixed #25; Unicode surrogate pairs (and emoji) input isn't working -- Microsoft Terminal renders the text correctly, but ConEmu and the default conhost still don't (and that isn't a Clink issue).
Fixed screen size bug in Readline on Windows.
Fixed the backwards values in the terminal.emulation setting.
Fixed .... so it works properly again.
Fixed case sensitive sorting of matches.
Fixed script error when %PATHEXT% is empty.
Fixed the exec.cwd Clink setting to default to true, so that the default behavior is consistent with how v0.4.x behaved.
Fixed the cd, md, rd, etc argmatchers to only match one argument to be consistent with the actual command syntax.

v1.1.4

Automatically detect when running inside ConEmu and disable Clink's Virtual Terminal emulation.
Added search-ignore-case inputrc variable that makes the history search commands case insensitive.
Suppress adding a space after completing a flag match that ends with : or = (e.g. msbuild -maxCpuCount:).
Report any errors while loading Lua scripts.
Report an error if a Lua script tries to add a flag string that begins with a letter.
Fixed slow printing of possible matches. Readline is inefficient about emitting output, so Clink supplies a custom implementation.
Fixed some bugs in auto detection of flag prefix characters.
Fixed backward compatibility for flags, and for args when merging two parsers by calling clink.arg.register_parser('foo') multiple times for the same command string.
Fixed truncated message when the last line of a prompt exceeds 128 characters.
Fixed abort (Ctrl+G or Esc) in non-incremental history search mode.
Fixed saved values for settings added by Lua scripts; now the saved value is available to the script immediately on adding the setting, and saved values are retained even if the setting isn't always added by the script.
Fixed (and documented) shorthand form for defining an argmatcher.
Fixed length of colored match prefix after a path separator.
Fixed normalizing a slash by itself (command / mustn't become command \ since that can interfere with completing flags).
Fixed the completion-auto-query-items inputrc variable.
Fixed the key binding list to correctly respect completion-display-width.
No visible effect yet: internal change that parses the input line to identify colors to use for each word (command, argument, flag, etc), but the colors aren't yet applied to the input line.

v1.1.3-alpha

Fixed argmatcher lookup to be more strict, like in Clink 0.4.9 (match exact names, or name plus an extension from %PATHEXT%).
Backward compatibility:
- Most things should work now.
- Dropping the new Clink on top of the vendor\clink directory in Cmder seems to work -- but make a backup before you try this at home!
API changes:
- Added log.info() function.
- Added Clink version numbers in clink.version_major, etc.
- Added _argmatcher:getwordbreakinfo() callback; removed _argmatcher:setprefixincluded() (it was a mess, and it was new to v1.x, so there's no compatibility concern with removing it).
- Deprecated _argmatcher:setflagprefix(); now it happens automagically when using _argmatcher:addflags().
- Introduced several deprecated functions to support backward compatibility.
Improvements to Lua debugger:
- Added lua.traceback_on_error, lua.break_on_error, and lua.break_on_traceback settings to make debugging script errors easier.
- Made pause() consistent about pausing in the caller (rather than sometimes inside the pause command itself).
- The debugger automatically shows the stack trace when entering debug mode, and on every pause.
- Show 3 lines of source context by default.
- The help list is sorted now.
- Fixed the set command in the debugger to behave as documented.

v1.1.2-alpha

Documentation is mostly updated; just the argmatcher Lua API and Clink command line options are left to be documented.
Added history.max_lines setting that controls how many lines of command history to save (1 to 50000, default is 2500).
Added readline.hide_stderr setting that can suppress stderr output from the Readline library.
For backward compatibility with 0.4.8, clink_inputrc files are loaded as well.
Lua script API changes:
- addmatch() in Lua scripts takes an optional match type argument.
- Removed displayable, aux, and suffix fields in matches.
- Revert the change to disallow mixing file/directory/symlink with other match types (it broke the tests and certain completion scenarios).
Fixed issues:
- #18 alt+digit then alt+ctrl+y isn't working.
- #17 arrow keys don't exit reverse-search-history like in bash.
- #16 problems with $T in doskey macros.
- #13 clink history delete <n> returns a CRT error.
Other fixes:
- There should be no more problems running on Windows Insider builds because Clink now uses Detours for hooking APIs.
- Fixed crash in insert-completions due to heap failure (introduced by the performance changes for displaying matches).
- Fixed clink and history built-in aliases (solve glitchy path problem).
- Fixed scrolling to top of screen buffer.
- Fixed env var and set completions.
- Fixed tilde-expand for quoted text.
- Fixed Esc in Readline's digit argument input mode (it doesn't try to cancel the mode, because that's not how Readline is documented to work).
- Fixed exit code from some clink command line options.
Set locale to UTF8 much earlier to avoid quirky behavior early in script processing.

v1.1.1-alpha

Exclusively use Readline's completion implementation. This (with fixes and enhancements in Readline itself) makes the completion experience much nicer and more sophisticated, and removes a lot of code that was added in v1.0.0a0.
Exclusively use Readline's key binding implementation. This makes it possible to have a single consistent way to set key bindings (inputrc) and for clink-show-help to list all key bindings, and removes a lot of code that was added in v1.0.0a0.
Converted all of Clink's internal key behaviors to be implemented as commands that can be bound in the inputrc file.
Rewrote and refactored the pagination routine to be used in multiple places.
Fixed prompt filtering to correctly use the specified priority order.
Readline library:
- Updated the Readline library from v6.2 to v8.0. This picked up lots of bug fixes and new capabilities (for example colored completions).
- Changed Readline to support backslash as a path separator.
- The pager prompt in Readline is optionally colored, controlled by the colour.interact Clink setting.
- Added completion-auto-query-items config variable (on by default) which asks whether to list possible matches when the number of lines listed will fill one screen page.
- Added history-point-at-end-of-anchored-search config variable in inputrc to make the cursor point behave like 4Dos/4NT/TakeCommand when searching forward and backward through command history.
- Fixed prev history at top of history.
- Fixed to get the current values of environment variables when needed, rather than always getting the value from whenever Clink was started.
- Fixed coloring directory completions.
- Fixed menu-complete for \dir and . and ...
- Fixed slow performance when displaying matches. Readline was calling stat() at least once per match (!!). A new match type field enables faster performance, coloring readonly and hidden file matches, applying filename completion rules only to filenames (vs branch names or other text strings), correct match de-duplication, and more. The Lua match APIs can supply the new match type.
- Fixed inserting a completion to happen as a single undo group.
- Fixed tilde to map to %USERPROFILE% instead of %APPDATA% on Windows.
Typing a directory by itself uses cd /d to change to the directory:
- Typing a directory with a trailing path separator changes to the directory.
- Typing ..\ changes to the parent directory.
- Typing ... or .... etc moves up an extra parent directory level for each extra dot (2 dots move up one parent, 3 dots moves up two parents, etc). A trailing path separator is optional when there are more than 2 dots.
- Typing - or cd - or chdir - changes to the previous directory.
Commands that are new, enhanced, or fixed:
- Added add-history and remove-history commands (similar to 4Dos/4NT/TakeCommand).
- Got the menu-complete, menu-complete-backward, and old-menu-complete commands working (they never worked properly before in Clink).
  - Also added a corresponding old-menu-complete-backward command for reverse order.
  - All of the *-menu-complete-* commands support wildcards (* and ?).
- Added clink-show-help command (Alt+H). The help now lists all key bindings, and it shows user-friendly key names (like A-Up or C-x,C-r or C-S-PgUp or A-C-S-F3).
- Added clink-popup-completions command that shows a popup window listing possible completions. Enter inserts the highlighted completion.
- Added clink-popup-directories command that shows a popup window listing recent directories. Enter changes to the highlighted directory, or Shift+Enter inserts the highlighted directory in the editing line (or Ctrl+Enter).
- Added clink-popup-history command that shows a popup window listing command history. Enter executes the highlighted command, or Shift+Enter jumps to the highlighted command in the history (or Ctrl+Enter).
- Added clink-scroll-lineup, clink-scroll-linedown, clink-scroll-page-up, clink-scroll-page-down, clink-scroll-top, and clink-scroll-bottom commands that do what it looks like they'd do and are bound to the keys it looks like they'd be.
- Added clink-expand-doskey command (Ctrl+Alt+f) that expands the current line according to the current doskey aliases.
- Added clink-expand-env-var command (Ctrl+Alt+e) that expands the environment variable at the cursor point.
- Added clink-exit command (Alt+F4) that exits CMD.
Fixed keyboard input issues:
- Esc is a bindable key now (\e[27;27~).
- Added more bindable key combinations (run clink echo then press keys to see the key sequence to use in the inputrc file).
- Ctrl+@ (NUL) didn't work.
- Ins toggles insert/overwrite mode.
- Unbound keys are ignored now, instead of inserting gibberish characters (part of the terminal internal key sequence).
- Fixed input handling so the quoted-insert command can work properly.
- Fixed Esc while searching.
- Fixed vi mode (was working in v0.4.9, but not in v1.0.x).
Fixed command history issues:
- The dont_add_to_history_cmds Clink setting is a space-delimited list of commands to not add to history.
- Fixed bleeding between history banks.
- Fixed uninitialized variable that made history updates intermittently do nothing or corrupt the other history bank.
- Fixed output from clink history to convert to UTF16 when writing to the console (but write UTF8 when output is redirected).
Fixed terminal output issues:
- Added terminal.emulate Clink setting that controls whether Clink does VT emulation or passes all ANSI escape codes directly to the console host. For example, this lets the prompt and completion coloring take advantage of more sophisticated ANSI escape codes such as XTerm 256 color and 16 bit color support.
- Added back support for the prefer-visible-bell config variable.
- Fixed underline support.
- Fixed handling for UTF8 output from Readline.
- Fixed invisible cursor point in Lua debugger.
Completions:
- Added match.sort_dirs Clink setting that specifies where to sort directories in the list of possible completions: before files, mixed in with files, or after files.
- Don't attempt completing incomplete UNC paths: at least the \\server\share\ path components are required (for anything shorter the OS APIs are guaranteed to fail, but will fail slowly).
- Fixed sorting to use Unicode aware locale based sorting (like Windows does) instead of dumb UTF8 byte comparisons.
- Fixed arbitrary limit on completions (had been limited to 64KB worth of completions).
- Fixed quoting spaces in completions.
- Fixed to use the same list as CMD for characters that require quoting.
- Fixed normalizing UNC paths.
- Fixed volume relative completions (e.g. x:foo).
- Disallow mixing file/directory/symlink with other match types. This was to avoid a confusing/malfunctioning case in match display and prefix highlighting.
Fixed UTF8 encoding in various Lua functions.
Fixed printing stderr output from Readline, Lua, and Clink.
Fixed crashes and other failures when starting Clink in 32 bit CMD.
Fixed some memory leaks that accumulated with each new line of input.
Fixed prompt filtering API to be backward compatible with v0.4.9 scripts.
Fixed Lua errors from clink set (it neglected to fully initialize Clink's Lua integration before loading Lua scripts).
Fixed UTF8 conversion bug that could truncate a string without fully converting it.
Fixed serious rampant memory corruption bug in v1.0.x (not present in v0.4.9), which had been causing intermittent malfunctions and data corruption and crashes.
Fixed multi-line doskey macros to show the prompt in between lines, like CMD does.
Removed the 4096 byte limit on input.
Renamed the Clink DLL back to what it was in v0.4.x, to fix compile time problems.
Other fixed issues:
- mridgers #544 Clink v1.0.0.a1 doesn't support cyrillic characters keyboard input on Windows 10 with console V2.
- mridgers #543 Not compatible with Windows Insider Build 20150.
- mridgers #537 Clink breaks the CMDS tool.
- mridgers #520 Clink 1.0.0.a1 - clink set history_io 1 Error.
- mridgers #519 Clink v1.0.0.a1 - -s|--scripts [path] command line arg removed?
- mridgers #516 Doskey $T not handled properly.
- mridgers #512 Command history missing in .history.
- mridgers #503 Keyboard shortcut for scrolling.
- mridgers #501 Ctrl+Backspace works now.
- mridgers #487 Clink breaks ConEmu-specific Escape codes.
- mridgers #480 History never saved.
- mridgers #465 Using LuaJIT (FFI).
- mridgers #456 Clear-screen not working properly when PROMPT is two lines long.
- mridgers #453 Wrong cursor position when a line contains non-printable characters.
- mridgers #442 Unable to paste more than 1024 characters using Ctrl+V.
- mridgers #422 Problem with filename modifiers.
- mridgers #420 Use NtSuspendProcess instead of CreateToolhelp32Snapshot to freeze the threads.
- mridgers #372 Provide a way to select a previous directory.
- mridgers #365 history-search behavior.
- mridgers #342 Clink_inputrc not being processed if it the clink_inputrc is a link (created via mklink).
Fixed many other bugs.

Releases from mridgers/clink original repo

v1.0.0a1 (alpha test release)

Improve terminal integration with the Readline library.
Internal improvements to the built-in ecma48 terminal emulator.
Fixed use after free in Doskey emulation.
Fixed dash-dash flag completion.
Search ancestors for a compatible target process (for when cmd.exe starts another process that subsequently starts clink; especially useful during development).
Use clink/terminal's wcwidth() implementation.
screen_buffer::set_cursor() should be relative to the visible area.
Try to adjust the cursor position better when resizing the terminal.
Some internal Lua functions needed the unquoted clink exe path.
The origin path now affects the hash in the dll cache, to guard against directory moves.
More code reorganization.

v1.0.0a0 (alpha test release)

Extensive code reorganization, refactoring, and rewriting -- multiple times -- almost everything was touched.
OS integration:
- Fixed Doskey macros on Win8, and on Win10.
- Fixed clink_x??.exe startup stall on Windows 10.
- Removed XP support. It doesn't load DLLs like Clink uses them.
- Removed Powershell support.
Readline integration:
- Search for multiple places for [.|_]inputrc (fixes mridgers #258).
- Disabled Readline's completion code, and only use the clink alternative code.
- Removed redundant slash translation and shims to make it happen.
- Removed control of Readline's suffix appending and disabled it.
clink commands and flags:
- Changed --cfgdir to --profile, it's no longer required, and added help about it.
- Added a --version option to print Clink's version.
