NAME
Getopt::Long::Less - Like Getopt::Long, but with less features
VERSION
This document describes version 0.091 of Getopt::Long::Less (from Perl
distribution Getopt-Long-Less), released on 2023-05-04.
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.
No support for GetOptions' "hash storage mode" (where the first argument
is a hashref) nor "classic mode" (where destination is not explicitly
specified). Basically, the arguments need to be pairs of option
specifications and destinations.
Currently no support for arrayref destination (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 :-)

CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull
requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You
can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally
on your system), you can install Dist::Zilla,
Dist::Zilla::PluginBundle::Author::PERLANCAR,
Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two
other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps
required beyond that are considered a bug and can be reported to me.
