I got a lot of great ideas, and I especially liked Wednesday's CodeJam, where I started building pyparsing_helper. Hacking on code while surrounded by sharp people to absorb energy and advice from is a great way to get things done! I finished it on the way home, so pyparsing_helper is officially a child of CodeMash!
This is what I had in mind when imagining "Kodos for pyparsing" last week.
One big bad fly in my ointment: pasting into pyparsing_helper isn't working. I don't know why. That's top priority for fixing for v0.1.1; I wonder if I'll have to switch out of Tk to get it to work.
[EDIT:] Paste does work under Windows, and it looks like it's an inherent Tkinter flaw... what's up with that? Tkinter's only been around for, oh, 15 years or so - and this core function is still unfixed? Maybe that's why all the cool kids quit using it years ago.
[EDIT #2:] OK, paste did work in *nix, but only in its Shift-Insert variety. pyparsing_helper 0.1.1 (available now) makes the more familiar Ctrl-V pasting available, too.
