I think that the external tree sitter parser python script is not installed correctly! Cheers.

jrfaller commented 5 months ago

Sure! Here: https://github.com/GumTreeDiff/tree-sitter-parser

Normally, since GumTree 4.0.0-beta3 there are the new gen.treesitter-ng bindings that allow using tree-sitter without our python parser (however no documentation on it at the moment).

Cheers.

Thanks, I install tree-sitter-javascript and tree-sitter-typescript. parse javascript is normal, can output xml normally result, But parsing typescript will prompt symbol not found error This is error stack image I'm not sure what other preparations need to be made.

Sorry I do not reproduce the bug. Can you detail the installation steps?
