Any character string or starting with a digit? In any case, that second parameter is then basically telling how to split the package name up into its constituents. > followed by ".tar", followed by an > arbitrary string. > > Paramter 1 can be a path, not only a filename, btw.

Except for some of the code details and "verpat:" (which I don't think have ever been described or used anywhere i can remember), that closely resembles what setup.exe is doing. Actually, setup parses like this: path goes from the start of string to the last path separator package name from the remainder of the string until the first "-" that's followed by a digit (exclusive the actual "-") package release from the last "-" until the ".tar.*" extension. Packages can have a "-src" and a "-patch" suffix. Only the "-src" suffix is currently used AFAIK, althoug I'd wish that "-debuginfo", "-devel" and maybe "-doc" could also be treated like that. > I'm really sorry, but AFAICS the code should be able to win the > obfuscated perl contest hands down. No noticable commenting either. https://www.unix-ag.uni-kl.de/~conrad/shocc/xd3.html#nr288 Perl that doesn't look like line noise even to the person that wrote it four weeks ago is inefficient. :-) > We could really need help from somebody knowing perl well enough > to understand and describe code :} I'd rather write new code when the objectives can be agreed upon.
