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 compconfig[describe_options]. -# 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. - -emulate -L zsh -local -h argspec dspec helpspec prelude xor -local -h -A amap dmap safe - -[[ -n "$1" ]] || return 1 -[[ ${(tP)${1}} = *-local ]] && { print -R NAME CONFLICT: $1 1>&2; return 1 } -safe[reply]="$1"; shift - -# First consume and save anything before the argument phrases - -helpspec=() -prelude=() - -while (($#)) -do - case $1 in - (argument|help|option) break;; - (*) prelude=("$prelude[@]" "$1"); shift;; - esac -done - -# Consume all the argument phrases and build the argspec array - -while (($#)) -do - amap=() - dspec=() - case $1 in - - # argument [POS] [means MSG] [action ACT] - (argument) - shift - while (($#)) - do - case $1 in - (<1->|\*) amap[position]="$1"; shift;; - (means|action) amap[$1]="$2"; shift 2;; - (argument|option|help) break;; - (*) print -R SYNTAX ERROR at "$@" 1>&2; return 1;; - esac - done - if (( $#amap )) - then - argspec=("$argspec[@]" "${amap[position]}:${amap[means]}:${amap[action]}") - fi;; - - # option OPT [follow HOW] [explain STR] {unless XOR} \ - # {[through PAT] [means MSG] [action ACT]} - (option) - amap[option]="$2"; shift 2 - dmap=() - xor=() - while (( $# )) - do - (( ${+amap[$1]} || ${+dmap[through]} )) && break; - case $1 in - (follow) - amap[follow]="${2:s/join/-/:s/close/-/:s/next//:s/split//:s/loose/+/:s/assign/=/:s/none//}" - shift 2;; - (explain) amap[explain]="[$2]" ; shift 2;; - (unless) xor=("$xor[@]" "${(@)=2}"); shift 2;; - (through|means|action) - while (( $# )) - do - (( ${+dmap[$1]} )) && break 2 - case $1 in - (through|means|action) dmap[$1]=":${2}"; shift 2;; - (argument|option|help|follow|explain|unless) break;; - (*) print -R SYNTAX ERROR at "$@" 1>&2; return 1;; - esac - done;; - (argument|option|help) break;; - (*) print -R SYNTAX ERROR at "$@" 1>&2; return 1;; - esac - if (( $#dmap )) - then - dspec=("$dspec[@]" "${dmap[through]}${dmap[means]:-:}${dmap[action]:-:}") - fi - done - if (( $#amap )) - then - argspec=("$argspec[@]" "${xor:+($xor)}${amap[option]}${amap[follow]}${amap[explain]}${dspec}") - fi;; - - # help PAT [means MSG] action ACT - (help) - amap[pattern]="$2"; shift 2 - while (($#)) - do - (( ${+amap[$1]} )) && break; - case $1 in - (means|action) amap[$1]="$2"; shift 2;; - (argument|option|help) break;; - (*) print -R SYNTAX ERROR at "$@" 1>&2; return 1;; - esac - done - if (( $#amap )) - then - helpspec=("$helpspec[@]" "${amap[pattern]}:${amap[means]}:${amap[action]}") - fi;; - (*) break;; - esac -done - -eval $safe[reply]'=( "${prelude[@]}" "${argspec[@]}" ${helpspec:+"-- ${helpspec[@]}"} "$@" )' - -# print -R _arguments "${prelude[@]:q}" "${argspec[@]:q}" ${helpspec:+"-- ${helpspec[@]:q}"} "$@:q" - -return 0 |
