tree-sitter version must be bound in requirements.txt

[mahtab-nejati]

I was trying this parser in a new environment where I installed tree-sitter==0.22.3 on MacOS, but I kept getting the following error:

Traceback (most recent call last):
  File "/.../tree-sitter-parser/tree-sitter-parser.py", line 55, in <module>
    main()
  File "/.../tree-sitter-parser/tree-sitter-parser.py", line 41, in main
    parsers = init_parsers(script_dir)

       ^^^^^^^^^^^^^^^^^^^^^^
AttributeError: type object 'tree_sitter.Language' has no attribute 'build_library'

My attempt in another environment with tree_sitter==0.20.1 was successful. It might be a good idea to bind the tree-sitter requirement to a specific version. You can see this discussion for more information.

I'm setting the same error, with a few tree_sitter versions between 0.20.1 and 0.22.6, so it doesn't seem directly related to that.

Thanks for the report. It seems that this function was removed : tree-sitter/py-tree-sitter#145 (comment) 😢

However, there does not seem to be any replacement... We might have to rethink how we integrate with the Python binding. In the meantime, you can try the Java binding (gen.treesitter-ng).

Cheers.

Good day to all.

Yeah, like jrfaller say - func was removed (See: tree-sitter/py-tree-sitter#241).

To use this func you need to downgrade tree-sitter to v0.21.

It helps me with swift analizing, but I still get some troubles :)

[jrfaller]

It's totally possible we do not have a yet a good config for swift ATM!

BTW @Armorov latest GumTree's commit add swift support to gumtree (using native tree sitter) if you want to try :-)
