Written a docopt grammar, interested ? about docopt-ng HOT 6 OPEN

docopt-parser includes PEG grammar for the docopt language completed and working with Arpeggio's clean peg parser.

The grammar is docopt.peg. The python test code is parser.py.

Oohh Exciting! This was a big dream of mine when I was working with the codebase last, thanks!

This is so cool! I am extremely into this train of thought, the current parser is a nightmare - adding type hints and my 2019ish refactoring was an effort at adding sanity to a fundamentally insane-ish design. It's better than it was, but deserves more love - and a PEG sounds like just the thing.

Hi @philip-h-dye , @itdaniher , I have a bit of time since I'm currently "available for employment" and new to jazzband.
Is this issue stalled at some stage? What is missing for it to move forward?
Is it a matter of including the grammar files from docopt-parser into a PR?
RTFMs gratefully accepted....

@blaisep this is really late, but perhaps you or someone else still is motivated. I would totally merge this if it comes together fairly cleanly. I took a look at docopt-parser and it looks like it is a bit messy, so it won't be a simple matter of just copying stuff over.

I think steps would be:

• create a new branch
• add the .peg grammar files
• add scripts/whatever to make it easy/reproducible to generate the .py parser from the .peg files. The generated parser should also be checked into git. It will need to stay in sync with the grammar files.
• modify the existing docopt/__init__.py to use this generated parser instead of the custom parsing logic in there now.
• ensure all existing tests pass. Maybe add some more tests if you think you are finding a new edge case.
• submit a PR for this branch

I think you're going to have to be mostly self-directed for those stages, I can provide some help but don't really want to sink a ton of time into it.
