CommandLine::OptionParser

ABOUT

CommandLine::OptionParser is part of the CommandLine suite of tools and is used for command line parsing. The parser integrates with CommandLine::Option, CommandLine::OptionData and CommandLine::Application.

The parser supports POSIX, Gnu and XTools style parsing options. It also gives you flexibility to provide non standard options. For example:

POSIX

OptionParser.new Option.new(:names => “-f”)

Gnu

OptionParser.new Option.new(:names => %w[–file -f])

XTools

OptionParser.new Option.new(:names => “-file”)

User

OptionParser.new(Option.new(

:names => %w(--file -file --files -files -f),
:arg_arity => [1,-1],
:arg_description => "file1 [file2, ...]"))

This option parser with a single option prints:

OPTIONS

    --file,-file,--files,-files,-f file1 [file2, ...]

There is document describing the various usage scenarios at its homepage.

After poking around in a few corporations, it was evident that option parsing was not understood. Nevertheless, many tools were built that did not conform to any of the POSIX, Gnu or XTools option styles. CommandLine::OptionParser was developed so that new application could be written that conformed to accepted standards, but non-standard option configurations could be handled as well to support legacy interfaces.

More information on OptionParser can be found on its homepage: optionparser.rubyforge.org
