Discussion about error recovery #244

Open gvanrossum opened 4 years ago

gvanrossum commented 4 years ago

Maybe we can continue the discussion (started here of my error recovery code here.

I could think of several different topics:

How the recovery actually works
How it compares to the paper
How I am validating it (see https://github.com/we-like-parsers/pegen/blob/master/corpus.py)
What I'd like to do next

Here's an incomplete TODO list:

[ ] Switch corpus.py to using a sqlite3 database, so we can store past results and do queries (on input and output)
[ ] Find more corpora -- the corpus I found is skewed heavily towards copy/paste errors into StackOverflow, unfortunately
[ ] Come up with more special cases for make_improved_syntax_error
