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 :-) HOMEPAGE Please visit the project's homepage at .

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. COPYRIGHT AND LICENSE This software is copyright (c) 2023, 2019, 2016, 2015 by perlancar .
