1.0.0 (2021-11-30)

⚠ BREAKING CHANGES

• node: drop Node 10 (feat(node)!: drop Node 10 #1919)
• implicitly private methods are now actually private
• deprecated reset() method is now private (call yargs() instead).
• yargs-factory: refactor yargs-factory to use class (refactor(yargs-factory)!: refactor yargs-factory to use class #1895)
• .positional() now allowed at root level of yargs.
• coerce: coerce is now applied before validation.
• async: yargs now returns a promise if async or check are asynchronous.
• middleware: global middleware now applied when no command is configured.
• feat!: improve support for async/await #1823 contains the following breaking API changes:
  • now returns a promise if handler is async.
  • onFinishCommand removed, in favor of being able to await promise.
  • getCompletion now invokes callback with err and `completions, returns promise of completions.
• tweaks to ESM/Deno API surface: now exports yargs function by default; getProcessArgvWithoutBin becomes hidBin; types now exported for Deno.
• find-up replaced with escalade; export map added (limits importable files in Node >= 12); yarser-parser@19.x.x (new decamelize/camelcase implementation).
• usage: single character aliases are now shown first in help output
• ts: yargs now ships with its own types
• drop support for EOL Node 8 (feat!: drop support for EOL Node 8 #1686)
• deps: 15.2.0
• deps: yargs-parser@17.0.0 no longer implicitly creates arrays out of boolean arguments when duplicates are provided
• deps: yargs-parser now throws on invalid combinations of config (feat(deps)!: yargs-parser@16.0.0 now throws on invalid combinations of config #1470)
• yargs-parser@16.0.0 drops support for Node 6
• drop Node 6 support (chore!: drop Node 6 support #1461)
• remove package.json-based parserConfiguration (refactor!: remove package.json-based parserConfiguration #1460)
• previously to this fix methods like yargs.getOptions() contained the state of the last command to execute.
• do not allow additional positionals in strict mode
• options with leading '+' or '0' now parse as strings
• dropping Node 6 which hits end of life in April 2019
• see yargs-parser@12.0.0 CHANGELOG
• we now warn if the yargs stanza package.json is used.
• Options absent from argv (not set via CLI argument) are now absent from the parsed result object rather tahn being set with undefined
• drop Node 6 from testing matrix, such that we'll gradually start drifting away from supporting Node 4.
• yargs-parser does not populate 'false' when boolean flag is not passed
• tests that assert against help output will need to be updated
• requiresArg now has significantly different error output, matching nargs.
• .usage() no longer accepts an options object as the second argument. It can instead be used as an alias for configuring a default command.
• previously hidden options were simply implied using a falsy description
• help command now only executes if it's the last positional in argv._
• version() and help() are now enabled by default, and show up in help output; the implicit help command can no longer be enabled/disabled independently from the help command itself (which can now be disabled).
• environment variables will now override config files, '--' is now populated rather than '_' when parsing is stopped.
• extends functionality now always loads the JSON provided, rather than reading from a specific key
• this pull requests introduces language features that require Node 4+.
