#autoload

# A simple compiler for _arguments descriptions.  The first argument of
# _arg_compile is the name of an array parameter in which the parse is
# returned.  The remaining arguments form a series of `phrases'.  Each
# `phrase' begins with one of the keywords "argument", "option", or "help"
# and consists of a series of keywords and/or values.  The syntax is as
# free-form as possible, but "argument" phrases generally must appear in
# the same relative position as the corresponding argument on the command
# line to be completed, and there are some restrictions on ordering of
# keywords and values within each phrase.
#
# Anything appearing before the first phrase or after the last is passed
# through verbatim.  (See TODO.)  If more detailed mixing of compiled and
# uncompiled fragments is necessary, use two or more calls, either with
# different array names or by passing the output of each previous call
# through the next.
#
# In the documentation below, brackets [ ] indicate optional elements and
# braces { } indicate elements that may be repeated zero or more times.
# Except as noted, bracketed or braced elements may appear in any order
# relative to each other, but tokens within each element are ordered.
#
#   argument [POS] [means MSG] [action ACT]
#
#     POS may be an integer N for the Nth argument or "*" for all, and
#      must appear first if it appears at all.
#     MSG is a string to be displayed above the matches in a listing.
#     ACT is (currently) as described in the compsys manual.
#
#   option OPT [follow HOW] [explain STR] {unless XOR} \
#    {[means MSG] [action ACT]} [through PAT [means MSG] [action ACT]]
#
#     OPT is the option, prefixed with "*" if it may appear more than once.
#     HOW refers to a following argument, and may be one of:
#       "close"   must appear in the same word (synonyms "join" or "-")
#       "next"    the argument must appear in the next word (aka "split")
#       "loose"   the argument may appear in the same or the next word ("+")
#       "assign"  as loose, but must follow an "=" in the same word ("=")
#     HOW should be suffixed with a colon if the following argument is
#      _not_ required to appear.
#     STR is to be displayed based on style `description'
#     XOR is another option in combination with which OPT may not appear.
#      It may be ":" to disable non-option completions when OPT is present.
#     MSG is a string to be displayed above the matches in a listing.
#     ACT is (currently) as described in the compsys manual.
#     PAT is either "*" for "all remaining words on the line" or a pattern
#      that, if matched, marks the end of the arguments of this option.
#      The "through PAT ..." description must be the last.
#     PAT may be suffixed with one colon to narrow the $words array to
#      the remainder of the command line, or with two colons to narrow
#      to the words before (not including) the next that matches PAT.
#
#   help PAT [means MSG] action ACT
#
#     ACT is applied to any option output by --help that matches PAT.
#      Do not use "help" with commands that do not support --help.
#     PAT may be suffixed with a colon if the following argument is
#      _not_ required to appear (this is usually inferred from --help).
#     MSG is a string to be displayed above the matches in a listing.

# EXAMPLE:
# This is from _gprof in the standard distribution.  Note that because of
# the brace expansion trick used in the "function name" case, no attempt
# is made to use `phrase' form; that part gets passed through unchanged.
# It could simply be moved to the _arguments call ahead of "$args[@]".
#
# _arg_compile args -s -{a,b,c,D,h,i,l,L,s,T,v,w,x,y,z} \
#              -{A,C,e,E,f,F,J,n,N,O,p,P,q,Q,Z}:'function name:->funcs' \
#              option -I means directory action _dir_list \
#              option -d follow close means "debug level" \
#              option -k means "function names" action '->pair' \
#              option -m means "minimum execution count" \
#              argument means executable action '_files -g \*$-\*$' \
#              argument means "profile file" action '_files -g gmon.\*' \
#              help '*=name*' means "function name" action '->funcs' \
#              help '*=dirs*' means "directory" action _dir_list
# _arguments "$args[@]"

# TODO:
# Verbose forms of various actions, e.g. (but not exactly)
#   "state foo"                  becomes "->foo"
#   "completion X explain Y ..." becomes "((X\:Y ...))"
#   etc.
# Represent leading "*" in OPT some other way.
# Represent trailing colons in HOW and PAT some other way.
# Stricter syntax checking on HOW, sanity checks on XOR.
# Something less obscure than "unless :" would be nice.
# Warning or other syntax check for stuff after the last phrase.
