What's new: - --config flag to pass a INI config file to parse. See config.ini. - Updated the modules scripts for configuration. Now needs to unset variables passed by CLI or config. - Fix release directory that was added in love file (maybe). - Properly escapes sed arguments. - chmod +x to getopt.sh and read_ini.sh - Fix #12

# getopt.sh:
|
|
# functions like getopts but do long-named options parsing
|
|
# and support optional arguments
|
|
#

# Version 1.0 1997 by Grigoriy Strokin (grg@philol.msu.ru), Public Domain
|
|
# Date created: December 21, 1997
|
|
# Date modified: December 21, 1997
|
|
#
|
|
# IMPORTANT FEATURES
|
|
#
|
|
# 1) Parses both short and long-named options
|
|
# 2) Supports optional arguments
|
|
# 3) Only uses bash builtins, thus no calls to external
|
|
# utilities such as expr or sed is done. Therefore,
|
|
# parsing speed is high enough
|
|
#
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# FUNCTION getopt
|
|
# Usage: getopt OPTLIST {"$@"|ALTERNATIVE_PARAMETERS}
|
|
#
|
|
# like getopts, but parse options with both required and optional arguments,
|
|
# Options with optional arguments must have "." instead of ":" after them.
|
|
# Furthemore, a variable name to place option name cannot be specified
|
|
# and is always placed in OPTOPT variable
|
|
#
|
|
# This function is provided for compatibility with getopts()
|
|
# OPTLIST style, and it actually calls getoptex (see bellow)
|
|
#
|
|
# NOTE that a list of parameters is required and must be either "$@",
|
|
# if processing command line arguments, or some alternative parameters.
|
|
#
|
|
# FUNCTION getoptex
|
|
# Usage: getoptex OPTION_LIST {"$@"|ALTERNATIVE_PARAMETERS}
|
|
#
|
|
# like getopts, but parse long-named options.
|
|
#
|
|
# Both getopt and getoptex return 0 if an option has been parsed,
|
|
# and 1 if all options are already parsed or an error occured
|
|
#
|
|
# Both getopt and getoptex set or test the following variables:
|
|
#
|
|
# OPTERR -- tested for whether error messages must be given for invalid options
|
|
#
|
|
# OPTOPT -- set to the name of an option parsed,
|
|
# or to "?" if no more options or error
|
|
# OPTARG -- set to the option argument, if any;
|
|
# unset if ther is no argument;
|
|
# on error, set to the erroneous option name
|
|
#
|
|
# OPTIND -- Initialized to 1.
|
|
# Then set to the number of the next parameter to be parsed
|
|
# when getopt or getoptex will be called next time.
|
|
# When all options are parsed, contains a number of
|
|
# the first non-option argument.
|
|
#
|
|
#
|
|
# OPTOFS -- If a parameter number $OPTIND containg an option parsed
|
|
# does not contain any more options, OPTOFS is unset;
|
|
# otherwise, OPTOFS is set to such a number of "?" signs
|
|
# which is equal to the number of options parsed
|
|
#
|
|
# You might not set variables OPTIND and OPTOFS yourself
|
|
# unless you want to parse a list of parameters more than once.
|
|
# Otherwise, you whould unset OPTIND (or set it to 1)
|
|
# and unset OPTOFS each time you want to parse a new parameters list
|
|
#
|
|
# Option list format is DIFFERENT from one for getopts or getopt.
|
|
# getopts-style option list can be converted to getoptex-style using a function optlistex
|
|
# (see bellow)
|
|
#
|
|
# DESCRIPTION of option list used with getoptex:
|
|
# Option names are separated by whitespace. Options consiting of
|
|
# more than one character are treated as long-named (--option)
|
|
#
|
|
# Special characters can appear at the and of option names specifying
|
|
# whether an argument is required (default is ";"):
|
|
# ";" (default) -- no argument
|
|
# ":" -- required argument
|
|
# "," -- optional argument
|
|
#
|
|
# For example, an option list "a b c help version f: file: separator."
|
|
# defines the following options:
|
|
# -a, -b, -c, --help, --version -- no argument
|
|
# -f, --file -- argument required
|
|
# --separator -- optional argument
|
|
#
|
|
# FUNCTION optlistex
|
|
# Usage new_style_optlist=`optlistex OLD_STYLE_OPTLIST`
|
|
#
|
|
# Converts getopts-style option list in a format suitable for use with getoptex
|
|
# Namely, it inserts spaces after each option name.
|
|
#
|
|
#
|
|
# HOW TO USE
|
|
#
|
|
# In order to use in your bash scripts the functions described,
|
|
# include a command ". getopt.sh" to the file containing the script,
|
|
# which will define functions getopt, getoptex, and optlistex
|
|
#
|
|
# EXAMPLES
|
|
#
|
|
# See files 'getopt1' and 'getopt2' that contain sample scripts that use
|
|
# getopt and getoptex functions respectively
|
|
#
