# Initialisation for new style completion. This mainly contains some helper
|
|
# functions and setup. Everything else is split into different files that
|
|
# will automatically be made autoloaded (see the end of this file). The
|
|
# names of the files that will be considered for autoloading are those that
|
|
# begin with an underscores (like `_condition).
|
|
#
|
|
# The first line of each of these files is read and must indicate what
|
|
# should be done with its contents:
|
|
#
|
|
# `#compdef <names ...>'
|
|
# If the first line looks like this, the file is autoloaded as a
|
|
# function and that function will be called to generate the matches
|
|
# when completing for one of the commands whose <names> are given.
|
|
# The names may also be interspersed with `-T <assoc>' options
|
|
# specifying for which set of functions this should be added.
|
|
#
|
|
# `#compdef -[pP] <patterns ...>'
|
|
# This defines a function that should be called to generate matches
|
|
# for commands whose name matches <pattern>. Note that only one pattern
|
|
# may be given.
|
|
#
|
|
# `#compdef -k <style> [ <key-sequence> ... ]'
|
|
# This is used to bind special completions to all the given
|
|
# <key-sequence>(s). The <style> is the name of one of the built-in
|
|
# completion widgets (complete-word, delete-char-or-list,
|
|
# expand-or-complete, expand-or-complete-prefix, list-choices,
|
|
# menu-complete, menu-expand-or-complete, or reverse-menu-complete).
|
|
# This creates a widget behaving like <style> so that the
|
|
# completions are chosen as given in the rest of the file,
|
|
# rather than by the context. The widget has the same name as
|
|
# the autoload file and can be bound using bindkey in the normal way.
|
|
#
|
|
# `#compdef -K <widget-name> <style> <key-sequence> [ ... ]'
|
|
# This is similar to -k, except it takes any number of sets of
|
|
# three arguments. In each set, the widget <widget-name> will
|
|
# be defined, which will behave as <style>, as with -k, and will
|
|
# be bound to <key-sequence>, exactly one of which must be defined.
|
|
# <widget-name> must be different for each: this must begin with an
|
|
# underscore, else one will be added, and should not clash with other
|
|
# completion widgets (names based on the name of the function are the
|
|
# clearest), but is otherwise arbitrary. It can be tested in the
|
|
# function by the parameter $WIDGET.
|
|
#
|
|
# `#autoload [ <options> ]'
|
|
# This is for helper functions that are not used to
|
|
# generate matches, but should automatically be loaded
|
|
# when they are called. The <options> will be given to the
|
|
# autoload builtin when making the function autoloaded. Note
|
|
# that this need not include `-U' and `-z'.
|
|
#
|
|
# Note that no white space is allowed between the `#' and the rest of
|
|
# the string.
|
|
#
|
|
# Functions that are used to generate matches should return zero if they
|
|
# were able to add matches and non-zero otherwise.
|
|
#
|
|
# See the file `compdump' for how to speed up initialisation.
|
|
|
|
# If we got the `-d'-flag, we will automatically dump the new state (at
|
|
# the end). This takes the dumpfile as an argument. -d (with the
|
|
# default dumpfile) is now the default; to turn off dumping use -D.
|
|
|
|
# If the dumpfile is being regenerated and you don't know why, you can use
|
|
# the -w flag to see if it was because -D was passed, zsh version mismatched,
|
|
# or number of files in $fpath differed.
|
|
|
|
# The -C flag bypasses both the check for rebuilding the dump file and the
|
|
# usual call to compaudit; the -i flag causes insecure directories found by
|
|
# compaudit to be ignored, and the -u flag causes all directories found by
|
|
# compaudit to be used (without security checking). Otherwise the user is
|
|
# queried for whether to use or ignore the insecure directories (which
|
|
# means compinit should not be called from non-interactive shells).

# This function is used to register or delete completion functions. For

|
# arguments depend on what type of completion function is defined. If
|
|
# none of the `-p' and `-k' options is given a function for a command is
|
|
# defined. The arguments after the function name are then interpreted as
|
|
# the names of the command for which the function generates matches.
|
|
# With the `-p' option a function for a name pattern is defined. This
|
|
# function will be invoked when completing for a command whose name
|
|
# matches the pattern given as argument after the function name (in this
|
|
# case only one argument is accepted).
|
|
# The option `-P' is like `-p', but the function will be called after
|
|
# trying to find a function defined for the command on the line if no
|
|
# such function could be found.
|
|
# With the `-k' option a function for a special completion keys is
|
|
# defined and immediately bound to those keys. Here, the extra arguments
|
|
# are the name of one of the builtin completion widgets and any number
|
|
# of key specifications as accepted by the `bindkey' builtin.
|
|
# In any case the `-a' option may be given which makes the function
|
|
# whose name is given as the first argument be autoloaded. When defining
|
|
# a function for command names the `-n' option may be given and keeps
|
|
# the definitions from overriding any previous definitions for the
|
|
# commands; with `-k', the `-n' option prevents compdef from rebinding
|
|
# a key sequence which is already bound.
|
|
# For deleting definitions, the `-d' option must be given. Without the
|
|
# `-p' option, this deletes definitions for functions for the commands
|
|
# whose names are given as arguments. If combined with the `-p' option
|
|
# it deletes the definitions for the patterns given as argument.
|
|
# The `-d' option may not be combined with the `-k' option, i.e.
|
|
# definitions for key function can not be removed.
|
|
#
|
|
# Examples:
|
|
#
|
|
# compdef -a foo bar baz
|
|
# make the completion for the commands `bar' and `baz' use the
|
|
# function `foo' and make this function be autoloaded
|
|
#
|
|
# compdef -p foo 'c*'
|
|
# make completion for all command whose name begins with a `c'
|
|
# generate matches by calling the function `foo' before generating
|
|
# matches defined for the command itself
|
|
#
|
|
# compdef -k foo list-choices '^X^M' '\C-xm'
|
|
# make the function `foo' be invoked when typing `Control-X Control-M'
|
|
# or `Control-X m'; the function should generate matches and will
|
|
# behave like the `list-choices' builtin widget
