# shFlags -- Advanced command-line flag library for Unix shell scripts.

|
|
#

# 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.
