In the past I’ve written my own Python command line processing module to emulate what I call command shell frameworks ala git, Mercurial, and Subversion. Sucked.
I tried the pyCLI module but it didn’t quite work for me.
After a few hitches, Doug Hellmann’s cliff module did the trick. Need a longer test drive, but so far it’s been highly useful. I don’t quite love the use of distribute hooks but I can live with it until I find a better solution. The baked in command REPL is a nice to have.
Using cliff has been a good way to paper over some fairly complex processing with a power user grade UI. Also quite easy to add new features with quick turnaround.
