As a proof of its quality, Fedora, Ubuntu and SuSe all ship a
python-argparse
package for older versions of python (<2.7). Given that the module is
self-
contained and as small as 80KB, wouldn't be feasible to add it as a build
dependency?
Note that that's huge compared to the current command line parser. The
current implementation doesn't even use 8K, and it's perfectly
self-contained as well.
I'd prefer if optparse was sufficient. The main advantage of argparse to
me seems to be in parsing command structures, such as "hg add ...", "hg
init ...". Since we don't do that in Cython I'd think optparse would be
sufficient, and that we should not ship argparse.
Could you try to explain what the advantages of your new implementation
are?
Assuming one switches to optparse, I find this line of reasoning highly
dubious... and think the burden should be the other way: Please argue
why custom, specific, low-level code is necesarry in Cython's command
line parser.
Using optparse/argparse have the obvious benefits that they are higher
level and so more stuff can be automated. In particular, better
automatically up-to-date command line help tracking changes elsewhere in
the codebase (such as directives that can be passed to -X).
