- sn6uv 10y agoHidden in there (under 1.0) is "new recursive descent parser #416". We've only just finished 1.0 and haven't had a chance to announce it properly yet.
- denfromufa 10y agois this limitation in ply?
- sn6uv 10y agoWe previously used ply but ran into a few issues: The main issue was that generating the tables was extremely slow (~15mins). We solved this by packaging the tables, but when the version of ply changed a table regeneration was forced on our users. The recursive descent parser was also simpler and significantly more performant. There's a short write-up on the PR: https://github.com/mathics/Mathics/pull/416 https://github.com/mathics/Mathics/pull/416
