digitalmars.D - Unable to parse command line arguments in unified way.

Hello

In my experience as a c/c++ programmer I've seen a lot of quick and 
dirty, primitive command line parsing implementations. Time and time 
again because they needed something that compiles on both linux(gcc) and 
windows(msvc) and avoid using external libraries.

Even very simple console application often needs some command line parsing.

Could one, simple, implementation be part of phobos, providing portability?

Some references I found:

std.optparse?"

I think you might have missed a couple modules (or maybe you left them off your
list intentionally because there's something wrong with them such as being too
out-of-date to use).

See http://www.prowiki.org/wiki4d/wiki.cgi?Phobos/PosixGetOpt for the fullest
list that I know of.

I agree that one of these should be added to Phobos. I don't know which one
(since I haven't studied the code of any of them or even tried to use any of
them yet), but it's obviously a common problem. And Phobos should be there to
solve our common problems. People can still use their own version if that's
what they like, but Phobos should have at least one implementation.

Thanks, you're right, I might have missed some.

For Linux a POSIX compliant command line argument parser is the best 
choice, for Windows, the options are simpler.

So do we take the lesser of both or go with the standard?

I would like to bring up mine, again. It uses the GNU "standard" for 
options, and it works on both Windows and Linux (so far as I'm able to 
tell; I've only tested it in bash and sh, so I'm not sure if other 
shells do strange things with arguments). If there are any features 
people would like to see, I am open to adding them.

I am also in the midst of writing documentation for it. My optparse has 
a fairly good selection of features, not all of which are laid out in 
the "opttest" module.

The URLs for it, again, are:
http://dsource.org/projects/pyd/browser/misc/optparse.d
http://dsource.org/projects/pyd/browser/misc/opttest.d

I'll post again when I have the documentation ready.

I looked at this list again and noticed that 3 of them are at least 
loosely based on Python's OptParse.

I don't think Python's OptParse would be used as basic of 3 separate 
ports except that it must be useful. Since Kirk has done the most recent 
port, it'd probably be easiest to use his version as a port. It's going 
to work on recent version of DMD, and he probably used the coolest new 
features of D to implement it. But we can still look at the other 
versions if someone wants to recommend them (or perhaps there's a 
problem with Kirk's version). But I bet Kirk's version would be the 
easiest to use since it's been written so recently.
