pythonic.optparse - Lua-based partial reimplementation of Python's optparse [2-3] command-line parsing module.

SYNOPSIS

local Optparse = Apollo.GetPackage("Optparse-0.3").tPackage local opt = OptParse:OptionParser{usage="%prog [options] [...]", version="foo 1.23", add_help_option=false} opt.add_option{"-h", "--help", action="store_true", dest="help", help="give this help", default="default"} opt.add_option{ "-f", "--force", dest="force", action="store_true", help="force overwrite of output file"}

local options, args = opt.parse_args()

DESCRIPTION

This library provides a command-line parsing[1] similar to Python optparse [2-3].

Note: Python also supports getopt [4].

STATUS

This module is fairly basic but could be expanded.

API

See source code and also compare to Python's docs [2,3] for details because the following documentation is incomplete.

opt = OptionParser {command=command, usage=usage, version=version, add_help_option=add_help_option, callback_write=callback_write}

Create command line parser.

callback_write: If provided, this function will be used for output instead of the command channel
command: Name of the slash command

opt.add_options{shortflag, longflag, action=action, metavar=metavar, dest=dest, help=help, default=default}

Add command line option specification.  This may be called multiple times.

opt.parse_args() --> options, args

Perform argument parsing.

DEPENDENCIES

None (other than Lua 5.1 or 5.2)
