Getopt::Long::Less - Like Getopt::Long, but with less features
This document describes version 0.090 of Getopt::Long::Less (from Perl distribution Getopt-Long-Less), released on 2019-02-02.
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
usestatement. 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=VALin addition to
--opt VALincluding 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 :-)
