# Increasingly loosely based on _cvs version 1.17.

# Styles, tags and contexts
# =========================
#
# If the `verbose' style is set (it is assumed by default), verbose
# descriptions are provided for many completed quantities derived
# dynamically such as subcommand names, labels, changes -- in fact,
# just about anything for which Perforce itself produces a verbose,
# one-line description.  It may be turned off in the context of each
# subcommand e.g.
#   zstyle ':completion:*:p4-labelsync:*' verbose false
# or for a particular tag, e.g. changes,
#   zstyle ':completion:*:changes' verbose false
# or just for top-level completion (i.e. up to and including completion
# of the subcommand):
#   zstyle ':completion:*:p4:*' verbose false
# or for p4 as a whole,
#   zstyle  ':completion:*:p4(-*|):*' verbose false
# This is actually handled by the `_describe' function underneath the
# Perforce completion system; it's mentioned here as verbosity adds
# significantly to a lot of the Perforce completions.
#
# Note that completing change numbers is not very useful if `verbose' is
# turned off.  There is no speed advantage for turning it off, either.
# (Changes are also known as changelists or changesets.  The functions
# and tags here all consistently use `changes'.)
#
# The style `max' can be set to a number which limits how many
# possibilities can be shown when selecting changes or jobs.  This is
# handled within Perforce, so the completion code may limit the number even
# further.  If not set explicitly, the value is taken to be 20 to avoid a
# huge database being output.  Set it to a larger number if necessary.
#
# The style `all-files' is used to tell the completion system to
# complete any file in a given context.  This is for use in places
# where it would, for example, only complete files opened for editing.
# See the next section for more.
#
# The style `depot-files' tells the system to complete files by asking
# Perforce for a list where it would otherwise complete files locally by
# the standard mechanism --- basically any time you don't use // notation
# and there is no restriction e.g. to opened files only.  There is likely
# to be a significant speed penalty for this; it is turned off by default
# in all contexts.  The advantage is that it cuts out files not maintained
# by Perforce.  (Again, note this is a style, not a tag.)  Contexts
# where this might be particularly useful include p4-diff or p4-diff2.
#
# The tags depot-files and depot-dirs also exist; they are used whenever
# the system is completing files or directories by asking Perforce
# to list them, rather than by using normal file completion.
#
# The tag subdirs is used to complete the special `...' which tells
# Perforce to search all subdirectories.  Hence you can turn this
# feature off by suitably manipulating your tags.
#
# Completion of files and their revisions
# =======================================
#
# File completion handles @ and # suffixes.  If the filename is completed,
# typing @ or # removes the space which was automatically added.
# The context used has `at-suffix' or `hash-suffix' in the position
# before the tag to indicate suffix completion (as always, ^Xh will
# show you all possible contexts).  This makes it possible
# to select changes, dates, labels and clients using the tag-order
# style.  For example,
#    zstyle ':completion:*:p4-*:at-suffix:*' tag-order changes '*'
# will force all completion after `@' to show changes first.  Executing
# _next_tags (usually ^x^n) will cycle between that and the remaining
# tags (dates, labels, clients).
#
# A # is automatically quoted when handled in this way; if the file is
# typed by hand or the completion didn't finish (e.g. you typed a character
# in the middle of menu completion), you probably need to type `\#' by
# hand.  The problem is that the completion system uses extended globbing
# and hence a pattern of the form `filename#' always matches `filename'
# (since e# matches any number of e's including one).  Hence this can look
# like an expansion which expands to `filename'.
#
# After @, you can complete changes (note the use of the style `max'
# above), labels, clients or even dates, while after `#' you can
# complete numeric revisions or the special revision names head, none,
# have.  These are available whether or not you completed the filename; if
# the file doesn't exist, numeric revisions won't work, but the rest will
# (though what Perforce will do with the resulting command is another matter).
#
# In addition, when completing after `file@', only changes specific to `file'
# will be shown (exactly the list of changes Perforce shows from the
# command `p4 changes file').  If this doesn't work, chances are that
# `file' does not exist.  Having a multi-directory match (literal `...')
# in `file' should work fine, since `p4 changes' recognises all normal
# Perforce file syntax.
#
# Some perforce commands allow you to specify a range of revisions or
# changes as `file@1,@2' or `file#1,#2'.  Currently, the second part of the
# revision range can always be completed (whether the command accepts them
# or not), but the comma after the first part of the range is only added
# automatically if the documentation suggests the command accepts ranges at
# that point.  This is an auto-removable suffix, so it will disappear if
# you hit space or return.  Typing a `#' at this point will insert a
# backslash, as before.  The # and @ are never added automatically; you
# have to select one by hand.
#
# File completion for some functions is restricted by the Perforce
# status of the file; for example, `p4 opened' only completes opened
# files (surprised?)  However, you can set the style (N.B. not tag)
# all-files; so, for example, you can turn off the limit in this case by
#   zstyle ':completion:*:p4-opened:*' all-files true
# Normally the file-patterns style would be used to control matching,
# but as the file types are not selected by globbing it doesn't work here
# However, if you set the all-files style, all filename completion is done
# by the standard mechanism; in this case, the file-patterns style works
# as usual.  The style ignored-patterns is available in any case, even
# without all-files; this is therefore generally the one to use.
#
# With `p4 diff', the shell will spot if you have used an option that
# allows you to diff unopened files (such as -f) and in that case offer
# all files; otherwise, it just offers opened files.
#
# Completion of changes
# =====================
#
# There is various extra magic available any time change numbers
# are completed, regardless of how this was reached, i.e.
# `p4 fixes -c ...' and `p4 diff filename.c@...' are treated the same way.
# Note, however, these only work if you are at the point where a change
# number would be completed.
#
# Firstly, as mentioned above there is a maximum for the number of
# changes which will be shown, given by the style max, or defaulting to 20.
# Only the most recent changes will be shown.  This is to avoid a speed
# penalty or clumsy output.  If a positive numeric argument is given
# when changes are being completed, the maximum is set (unconditionally)
# to that number instead.
#
# It is also possible to give a negative numeric prefix to a listing widget
# (i.e. typically whatever is bound to ^D).  If there is already a change
# number on the line, e.g. from cycling through a menu of choices, the full
# description for that change is shown in the format of a completion
# listing.  [TODO: this could be made configurable with a style.]
#
# It may be necessary to abandon the current completion attempt before
# typing this to force the completion system to display the new text.
# Replacing delete-char-or-list with the following user defined widget
# (create with `zle -N ...') will force this for any negative prefix argument.
#    (( ${NUMERIC:-0} < 0 )) && (( CURSOR = CURSOR ))
#    zle delete-char-or-list
#
# Completion of jobs
# =================
#
# Completing jobs uses the same logic for the numeric prefix as completing
# changes: a positive prefix changes the maximum number of jobs which
# will be shown, and a negative prefix when listing shows the full
# text for the job whose name is currently inserted on the command line.
# In this case, the entire text of the word being completed is assumed
# to constitute the job name (which is almost certainly correct).
#
# Completion of dates
# ===================
#
# In a file revision specification it is possible to give a date
# in the form file@YYYY/MM/DD:hh:mm:ss, which may be completed.  This
# is ever so slightly less silly than it sounds.  Any component entered
# by hand with the appropriate suffix will be ignored; any component
# completed will be set to the current value.  Hence you can easily
# specify, say, one month ago by using the completed value for all
# components except the month and setting that to one less.  The shell
# will also happily append the appropriate suffix if you try to complete
# after anything which is already the appropriate width.  (Perforce
# supports two-digit years, but these are confusing and no longer
# particularly useful as they refer to the twentieth century, so
# the shell does not.)
#
# Calls to p4
# ===========
#
# Much of the information from Perforce is provided by calls to p4
# commands.  This is done via the _call_program interface, as described
# in the zshcompletesys manual page.  Hence a suitable context with the
# `command' style allows the user to take control of this call.
# The tags used are the name of the p4 command, or in the case of
# calls to help subcommands, `help-<subcommand>'.  Note that if the
# value of the style begins with `-', the arguments to the perforce
# command are appended to the remaining words of the style before calling
# the command.
#
# Programmes taking p4-style arguments
# ====================================
#
# It is possible to use the _perforce completion with other commands
# which behave like a subcommand of p4 by setting the service type
# to p4-<subcommand>.  For example,
#   compdef _perforce p4cvsmap=p4-files
# says that the command `p4cvsmap' takes arguments like `p4 files'.
# Often the options will be different; if this is a problem, you
# will need to write your own completer which loads _perforce and
# calls its functions directly.
#
# TODO
# ====
#
# No mechanism is provided for completely ignoring certain files not
# handled by Perforce as with .cvsignore.  This could be done ad hoc.
# However, the ignored-patterns style and the parameter $fignore are
# of course applied as usual, so setting ignored-patterns for the
# context `:completion:*:p4[-:]*' should work.
