+
+# 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, changelists -- 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. changelists,
+#   zstyle ':completeion:*:changelists' 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 changelists (which are just numbers) is not very
+# useful if `verbose' is turned off.  There is no speed advantage for
+# turning it off, either.
+#
+# The style `max' can be set to a number which limits how many
+# possibilities can be shown when selecting changelists 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.
+#
+# 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 changelists (note the use of the style `max'
+# above), labels or clients (but not 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.
+#
+# 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).
+#
+# 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.
+#
+# 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.
