# $Id$ # vim:et:ft=sh:sts=2:sw=2 # # Copyright 2008 Kate Ward. All Rights Reserved. # Released under the LGPL (GNU Lesser General Public License) # # shFlags -- Advanced command-line flag library for Unix shell scripts. # http://code.google.com/p/shflags/ # # Author: kate.ward@forestent.com (Kate Ward) # # This module implements something like the google-gflags library available # from http://code.google.com/p/google-gflags/. # # FLAG TYPES: This is a list of the DEFINE_*'s that you can do. All flags take # a name, default value, help-string, and optional 'short' name (one-letter # name). Some flags have other arguments, which are described with the flag. # # DEFINE_string: takes any input, and intreprets it as a string. # # DEFINE_boolean: does not take any arguments. Say --myflag to set # FLAGS_myflag to true, or --nomyflag to set FLAGS_myflag to false. For short # flags, passing the flag on the command-line negates the default value, i.e. # if the default is true, passing the flag sets the value to false. # # DEFINE_float: takes an input and intreprets it as a floating point number. As # shell does not support floats per-se, the input is merely validated as # being a valid floating point value. # # DEFINE_integer: takes an input and intreprets it as an integer. # # SPECIAL FLAGS: There are a few flags that have special meaning: # --help (or -?) prints a list of all the flags in a human-readable fashion # --flagfile=foo read flags from foo. (not implemented yet) # -- as in getopt(), terminates flag-processing # # EXAMPLE USAGE: # # -- begin hello.sh -- # #! /bin/sh # . ./shflags # DEFINE_string name 'world' "somebody's name" n # FLAGS "$@" || exit $? # eval set -- "${FLAGS_ARGV}" # echo "Hello, ${FLAGS_name}." # -- end hello.sh -- # # $ ./hello.sh -n Kate # Hello, Kate. # # CUSTOMIZABLE BEHAVIOR: # # A script can override the default 'getopt' command by providing the path to # an alternate implementation by defining the FLAGS_GETOPT_CMD variable. # # NOTES: # # * Not all systems include a getopt version that supports long flags. On these # systems, only short flags are recognized. #============================================================================== # shFlags # # Shared attributes: # flags_error: last error message # flags_output: last function output (rarely valid) # flags_return: last return value # # __flags_longNames: list of long names for all flags # __flags_shortNames: list of short names for all flags # __flags_boolNames: list of boolean flag names # # __flags_opts: options parsed by getopt # # Per-flag attributes: # FLAGS_<flag_name>: contains value of flag named 'flag_name' # __flags_<flag_name>_default: the default flag value # __flags_<flag_name>_help: the flag help string # __flags_<flag_name>_short: the flag short name # __flags_<flag_name>_type: the flag type # # Notes: # - lists of strings are space separated, and a null value is the '~' char. # return if FLAGS already loaded [ -n "${FLAGS_VERSION:-}" ] && return 0 FLAGS_VERSION='1.0.4pre' # return values that scripts can use FLAGS_TRUE=0 FLAGS_FALSE=1 FLAGS_ERROR=2 # determine some reasonable command defaults __FLAGS_UNAME_S=`uname -s` case "${__FLAGS_UNAME_S}" in BSD) __FLAGS_EXPR_CMD='gexpr' ;; *) __FLAGS_EXPR_CMD='expr' ;; esac # commands a user can override if needed FLAGS_EXPR_CMD=${FLAGS_EXPR_CMD:-${__FLAGS_EXPR_CMD}} FLAGS_GETOPT_CMD=${FLAGS_GETOPT_CMD:-getopt} # specific shell checks if [ -n "${ZSH_VERSION:-}" ]; then setopt |grep "^shwordsplit$" >/dev/null if [ $? -ne ${FLAGS_TRUE} ]; then _flags_fatal 'zsh shwordsplit option is required for proper zsh operation' fi if [ -z "${FLAGS_PARENT:-}" ]; then _flags_fatal "zsh does not pass \$0 through properly. please declare' \ \"FLAGS_PARENT=\$0\" before calling shFlags" fi fi # can we use built-ins?
