Problems Faced This Week

<meta charset="utf-8">

• While working on making the BoolOp node have multiple values of expr type, I faced numerous issues. I could not make it match the output from the current parser. Thirumalai and I collaboratively worked on it and overcame most of the problems. It is mostly complete and requires some minor changes before submitting the final patch.

Plans For Upcoming Week

<meta charset="utf-8">

• The new parser still generates many errors I found while testing on Python files from NumPy and SymPy repos. I will open issues related to each of these errors and fix them. One good sign I noticed was that whatever AST the new parser generates (after commenting out the error causing part) is highly accurate compared to the existing one.
