Zsh Angel IQ System

A bunch of intelligent extensions to Zsh. Features:

1. Smart console – a TUI application allowing to run configure & make and open editor on exact locations of reported errors.
2. In-shell Ctags browser – list all symbols in TAGS index created with Universal Ctags and open editor on their source locations.
3. Angel Swiss Knife
4. An extension to Zinit plugin manager – action complete – press Alt-a to complete a name of plugin and Alt-c to complete a name of ice modifier.
5. A set of global aliases in the form NAME…STR allowing clever tests of variable contents. The strings are:
   • EMPTYSTR – [:space:][:INCOMPLETE:][:INVALID:]$'\e']# – any number of spaces, incomplete chars or invalid chars – essentially an empty string,
   • INVALIDSTR – *[[:INCOMPLETE:][:INVALID:]]* – a string holding at least one invalid character,
   • EMORINSTR – empty or invalid string,
   • FUNCSTR – a string of the form: abc() {… with all possible variants (like e.g.: preceding function keyword),
   • IDSTR – a string with all characters allowed in Zsh variable name,
   • PRINTSTR – a string with all characters being printable,
   • WRONGSTR – a string either empty, invalid, control-chars only, zeroes-only or non-printable only,
   • ZEROSTR – a string with only 0 character,
   • CTRLSTR – a string consisting of only control characters.

To use the global alias do:

if [[ $var == WRONGSTR ]]; then
…
fi

There are also negation aliases, as ~NAMESTR, i.e.:

if [[ $var == ~WRONGSTR ]]; then
    print Good \$var contents
fi

Build console

Angel open console

After entering angel open (aliased to apo) a fzf-like TUI opens. It shows all files in current directory by default (configure by ANGEL_DEFAULT_COMMAND) or the lines read at standard input, if it'll be detected:

After pressing F2, the currently selected file will be open, with syntax highlighting (requires highlight, source-highlight or bat):

Pressing ENTER on any line will open $VISUAL/$EDITOR/$PAGER scrolled to that line.

Pressing F3 will open Git Diff view.

Pressing ENTER on any line will open $VISUAL/$EDITOR/$PAGER scrolled to that line.

Any view can be greped – angel open starts with search prompt active, so you can enter the search-keyword to have either files, file preview contents or git diff lines filtered with it. Multiple keywords are allowed. Below is a file preview grepped:
