Bug #84487 for Getopt-Long-Descriptive: [RT #79982] Getopt-Long-Descriptive: Show whether an option requires an argument in usage

Hi, I have created a couple of patches to ticket #79982 that adds an "argument" to the usage output when ":" or "=" is used in the option spec. Note that "{N,M}" specifications are ignored, so it won't be correct for those cases. I have attached the 3 patches[1], a small prototype attempt to convert Lintian's argument parsing to Getopt::Long::Descriptive and the usage from that script with and without the attached patches applied. Notice that 0003 also reduces the spacing between the arguments and their description. Part of it is that it calculates the space exactly instead of heurestically. Personally I consider this a feature because it gives more room to descriptions[2], but feel free to adjust the spacing. I am more interested in showing the argument. ~Niels [1] If you are using a (public) VCS, it might be prudent to at least merge 0002 and 0003 as 0002 breaks spacing rules, which is fixed by 0003. [2] With the patched variant has 6 lines fewer than the "normal" one.
