Second, for 'sticky' short options, like '-cd' above, the library can break them in parts. Again, in example we get:
("-c", ) ("-d", ) *
The 'c' letter is recognized, and the 'd' letter is not. I find this behaviour better than marking the entire '-cd' as unrecognised.
I agree that this is the desirable behavior.
Finally, the new functionality might not work nice with long options that start with a single dash (allow_long_disguise style option):
-foo
will be considered as short option '-f' with value 'oo', and never as long option 'foo'.
Would this only be if "f" is a registered option, or even if it is unregistered? I'd think in the unregistered case you'd end up with -f and two -o's as in the -cd case above. Whichever the case, I agree that -foo should not be treated the same way as --foo. But I grew up using GNU tools, so I'm biased towards the double-dash syntax. Overall I think this is great. It makes it straightforward to chain option processing across different modules. -- Caleb Epstein caleb dot epstein at gmail dot com
