# 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 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.
# 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).

# Loading it now ensures that the `funcstack' parameter is always correct.
: $funcstack
# This function is used to register or delete completion functions. For
# registering completion functions, it is invoked with the name of the
# function as it's first argument (after the options). The other
# 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
#
# compdef -d bar baz
# delete the definitions for the command names `bar' and `baz'
