error when calling get_language('any_language')

[mohmehdi]

tree-sitter has updated the Language class and how they initialize it so now it takes just one parameter. here: example usage

[scanny]

Quick-fix is to downgrade to treesitter==0.21.3:

$ pip install -U tree-sitter==0.21.3

In my particular case that results in an unwelcome warning being emitted to the console at runtime:

.../python3.11/site-packages/tree_sitter/__init__.py:36: FutureWarning: Language(path, name) is deprecated. Use Language(ptr, name) instead.

but that is easily avoided in my case using the python -Wignore ... command-line flag.

FWIW an example traceback:

Traceback (most recent call last):
  File "/Users/samuelainsworth/dev/SWE-agent/poop.py", line 5, in <module>

               ^^^^^^^^^^^^^^^^^^^^^^

@samuela I don't think they are going to update this repo.

The main tree-sitter project had a rewrite.

For python do this(from py-tree-sitter repo):

pip install tree-sitter-python

import tree_sitter_python as tspython
from tree_sitter import Language, Parser

PY_LANGUAGE = Language(tspython.language())

For any other languages, you have to wait until someone makes the PyPI package for it

I faced the same issue. I downgraded my version but not sure which one. Here are my versions of both tree-sitter & tree-sitter-languages Name: tree-sitter Version: 0.20.4 Name: tree-sitter-languages Version: 1.10.2

[restlessronin]

I'm facing this issue. I downgraded to 0.21.3 as suggested in the first response

tree-sitter: 0.21.3 tree-sitter-languages: 1.10.2

seems to be working so far

Same here for:

from tree_sitter_languages import get_language

TS_LANGUAGE = get_language('typescript')

Works for:

tree-sitter: 0.21.3
tree-sitter-languages: 1.10.2

but not for

tree-sitter: 0.22  (or higher)

where I get

I brought this issue to the attention of tree-sitter authors in this issue:

Versions 0.22+ break tree_sitter_languages.get_language

How to load customized languages (compiled to a .so file) now?
