Re: Command line parsing with genparse

[Alfred M. Szmidt]

   1. It does a significant part of the work at compile time. So the
      generated code can be quite simple and fast.

It is parsing arguments, it doesn't need to be super fast.  As for
simplicity, having used argp for alot of things, I all I know is that
getopt/getopt_long are a pain.

   2. It is able to auto generate a highly configurable usage
      function.  Many of the replies on my previous posts to the
      coreutils mailing list were about the usage function. argp also
      can print a usage function but how far can you customize it?

You can customize as much as you would like.

      Has anybody tried to convert one of the coreutils tools to use
      argp? I would be very interested to see a comparison to the
      genparse solution.

Deberashi converted a bunch of tools in inetutils to use argp instead
of getopt/getopt_long.  The thing with getting such a patch considered
for coreutils is that you'd need to convert everything in one go.
Which is alot of work.
