NAME

Getopt::Long::Less - Like Getopt::Long, but with less features

VERSION

This document describes version 0.07 of Getopt::Long::Less (from Perl distribution Getopt-Long-Less), released on 2016-12-02.

DESCRIPTION

This module is a reimplementation of Getopt::Long, with less features/configurability. Only the subset which I'm currently using (which I think already serves a lot of common use cases for a lot of people too) is implemented.

Only three functions are implemented: GetOptions, GetOptionsFromArray, and Configure.

No configuring from use statement. No OO interface.

Much much less modes/configuration. No support for POSIXLY_CORRECT. We always do bundling (this is not Getopt::Long's default), we never ignore case (this is not Getopt::Long's default), we always permute, we always autoabbreviate, we always do GNU compatibility (allow --opt=VAL in addition to --opt VAL including allowing --opt=), we never do getopt_compat. Basically currently there's no mode you can configure (although pass_through might be added in the future).

No autoversion, no autohelp. No support to configure prefix pattern.

Currently no support for arrayref handler (e.g. "foo=s" => \@ary). No support for array desttype ('foo=s@' => ...).

Also, this module requires 5.010.

So what's good about this module? Slightly less compile time overhead, due to less code. This should not matter for most people. I just like squeezing out milliseconds from startup overhead of my CLI scripts. That's it :-)

Sample startup overhead benchmark:

                     Rate    load_gl load_glless   perl
load_gl     68.78+-0.66/s         --      -43.6% -87.8%
load_glless    122+-2.1/s 77.4+-3.5%          -- -78.4%
perl           566+-7.9/s   723+-14%    364+-10%     --

Average times:
  perl       :     1.7668ms
  load_glless:     8.1967ms
  load_gl    :    14.5391ms
