Hi, would it be an option to use Genparse (http://genparse.sourceforge.net/) for command line parsing in the GNU Coreutils?
I'm one of the developers of Genparse and I recently used some of the well known Coreutils as an exercise for testing Genparse (see http://genparse.sourceforge.net/examples.html). Using Genparse for generating the command line parsing code could reduce the amount of coreutils source code because the input to Genparse is a short config file only. The overhead of writing the parser code would be delegated to the tool then. The Genparse generated parsers call getopt() (or getopt_long()) exactly the same way the Coreutils's command line parsers do it today. This wouldn't be changed. So the code Genparse generates will be very similar to the existing hand written parsers of the individual Coreutils tools. But calling getopt() is only part of the work, preparing and evaluating the results of getopt() also causes coding work which could be delegated to Genparse. Genparse also automatically generates a help screen which would no longer have to be done manually.
