  363. # ZSH COMPLETION REFERENCE
  364. #
  365. # For the convenience of developers who aren't especially familiar with zsh
  366. # completion functions, a brief reference guide follows. This is in no way
  367. # comprehensive; it covers just enough of the basic structure, syntax, and
  368. # conventions to help someone make simple changes like adding new options. For
  369. # more complete documentation regarding zsh completion functions, please see the
  370. # following:
  371. #
  372. # * http://zsh.sourceforge.net/Doc/Release/Completion-System.html
  373. # * https://github.com/zsh-users/zsh/blob/master/Etc/completion-style-guide
  374. #
  375. # OVERVIEW
  376. #
  377. # Most zsh completion functions are defined in terms of `_arguments`, which is a
  378. # shell function that takes a series of argument specifications. The specs for
  379. # `rg` are stored in an array, which is common for more complex functions; the
  380. # elements of the array are passed to `_arguments` on invocation.
  381. #
  382. # ARGUMENT-SPECIFICATION SYNTAX
  383. #
  384. # The following is a contrived example of the argument specs for a simple tool:
  385. #
  386. # '(: * -)'{-h,--help}'[display help information]'
  387. # '(-q -v --quiet --verbose)'{-q,--quiet}'[decrease output verbosity]'
  388. # '!(-q -v --quiet --verbose)--silent'
  389. # '(-q -v --quiet --verbose)'{-v,--verbose}'[increase output verbosity]'
  390. # '--color=[specify when to use colors]:when:(always never auto)'
  391. # '*:example file:_files'
  392. #
  393. # Although there may appear to be six specs here, there are actually nine; we
  394. # use brace expansion to combine specs for options that go by multiple names,
  395. # like `-q` and `--quiet`. This is customary, and ties in with the fact that zsh
  396. # merges completion possibilities together when they have the same description.
  397. #
  398. # The first line defines the option `-h`/`--help`. With most tools, it isn't
  399. # useful to complete anything after `--help` because it effectively overrides
  400. # all others; the `(: * -)` at the beginning of the spec tells zsh not to
  401. # complete any other operands (`:` and `*`) or options (`-`) after this one has
  402. # been used. The `[...]` at the end associates a description with `-h`/`--help`;
  403. # as mentioned, zsh will see the identical descriptions and merge these options
  404. # together when offering completion possibilities.
  405. #
  406. # The next line defines `-q`/`--quiet`. Here we don't want to suppress further
  407. # completions entirely, but we don't want to offer `-q` if `--quiet` has been
  408. # given (since they do the same thing), nor do we want to offer `-v` (since it
  409. # doesn't make sense to be quiet and verbose at the same time). We don't need to
  410. # tell zsh not to offer `--quiet` a second time, since that's the default
  411. # behaviour, but since this line expands to two specs describing `-q` *and*
  412. # `--quiet` we do need to explicitly list all of them here.
  413. #
  414. # The next line defines a hidden option `--silent` — maybe it's a deprecated
  415. # synonym for `--quiet`. The leading `!` indicates that zsh shouldn't offer this
  416. # option during completion. The benefit of providing a spec for an option that
  417. # shouldn't be completed is that, if someone *does* use it, we can correctly
  418. # suppress completion of other options afterwards.
  419. #
  420. # The next line defines `-v`/`--verbose`; this works just like `-q`/`--quiet`.
  421. #
  422. # The next line defines `--color`. In this example, `--color` doesn't have a
  423. # corresponding short option, so we don't need to use brace expansion. Further,
  424. # there are no other options it's exclusive with (just itself), so we don't need
  425. # to define those at the beginning. However, it does take a mandatory argument.
  426. # The `=` at the end of `--color=` indicates that the argument may appear either
  427. # like `--color always` or like `--color=always`; this is how most GNU-style
  428. # command-line tools work. The corresponding short option would normally use `+`
  429. # — for example, `-c+` would allow either `-c always` or `-calways`. For this
  430. # option, the arguments are known ahead of time, so we can simply list them in
  431. # parentheses at the end (`when` is used as the description for the argument).
  432. #
  433. # The last line defines an operand (a non-option argument). In this example, the
  434. # operand can be used any number of times (the leading `*`), and it should be a
  435. # file path, so we tell zsh to call the `_files` function to complete it. The
  436. # `example file` in the middle is the description to use for this operand; we
  437. # could use a space instead to accept the default provided by `_files`.
  438. #
  439. # GROUPING ARGUMENT SPECIFICATIONS
  440. #
  441. # Newer versions of zsh support grouping argument specs together. All specs
  442. # following a `+` and then a group name are considered to be members of the
  443. # named group. Grouping is useful mostly for organisational purposes; it makes
  444. # the relationship between different options more obvious, and makes it easier
  445. # to specify exclusions.
  446. #
  447. # We could rewrite our example above using grouping as follows:
  448. #
  449. # '(: * -)'{-h,--help}'[display help information]'
  450. # '--color=[specify when to use colors]:when:(always never auto)'
  451. # '*:example file:_files'
  452. # + '(verbosity)'
  453. # {-q,--quiet}'[decrease output verbosity]'
  454. # '!--silent'
  455. # {-v,--verbose}'[increase output verbosity]'
  456. #
  457. # Here we take advantage of a useful feature of spec grouping — when the group
  458. # name is surrounded by parentheses, as in `(verbosity)`, it tells zsh that all
  459. # of the options in that group are exclusive with each other. As a result, we
  460. # don't need to manually list out the exclusions at the beginning of each
  461. # option.
  462. #
  463. # Groups can also be referred to by name in other argument specs; for example:
  464. #
  465. # '(xyz)--aaa' '*: :_files'
  466. # + xyz --xxx --yyy --zzz
  467. #
  468. # Here we use the group name `xyz` to tell zsh that `--xxx`, `--yyy`, and
  469. # `--zzz` are not to be completed after `--aaa`. This makes the exclusion list
  470. # much more compact and reusable.
  471. #
  472. # CONVENTIONS
  473. #
  474. # zsh completion functions generally adhere to the following conventions:
  475. #
  476. # * Use two spaces for indentation
  477. # * Combine specs for options with different names using brace expansion
  478. # * In combined specs, list the short option first (as in `{-a,--text}`)
  479. # * Use `+` or `=` as described above for options that take arguments
  480. # * Provide a description for all options, option-arguments, and operands
  481. # * Capitalise/punctuate argument descriptions as phrases, not complete
  482. # sentences — 'display help information', never 'Display help information.'
  483. # (but still capitalise acronyms and proper names)
  484. # * Write argument descriptions as verb phrases — 'display x', 'enable y',
  485. # 'use z'
  486. # * Word descriptions to make it clear when an option expects an argument;
  487. # usually this is done with the word 'specify', as in 'specify x' or
  488. # 'use specified x')
  489. # * Write argument descriptions as tersely as possible — for example, articles
  490. # like 'a' and 'the' should be omitted unless it would be confusing
  491. #
  492. # Other conventions currently used by this function:
  493. #
  494. # * Order argument specs alphabetically by group name, then option name
  495. # * Group options that are directly related, mutually exclusive, or frequently
  496. # referenced by other argument specs
  497. # * Use only characters in the set [a-z0-9_-] in group names
  498. # * Order exclusion lists as follows: short options, long options, groups
  499. # * Use American English in descriptions
  500. # * Use 'don't' in descriptions instead of 'do not'
  501. # * Word descriptions for related options as similarly as possible. For example,
  502. # `--foo[enable foo]` and `--no-foo[disable foo]`, or `--foo[use foo]` and
  503. # `--no-foo[don't use foo]`
  504. # * Word descriptions to make it clear when an option only makes sense with
  505. # another option, usually by adding '(with -x)' to the end
  506. # * Don't quote strings or variables unnecessarily. When quotes are required,
  507. # prefer single-quotes to double-quotes
  508. # * Prefix option specs with `$no` when the option serves only to negate the
  509. # behaviour of another option that must be provided explicitly by the user.
  510. # This prevents rarely used options from cluttering up the completion menu
