Cannot find DLL: (libtree-sitter-python libtree-sitter-python.dll) No such file or directory

[vjohansen]

GNU Emacs 29.2 (build 2, x86_64-w64-mingw32) of 2024-02-01

When I call python-ts-mode in a py-file it fails with

■  Warning (treesit): Cannot activate tree-sitter, because language grammar for python is unavailable (not-found): (libtree-sitter-python libtree-sitter-python.dll) No such file or directory

Steps

• Install tree-sitter-langs-0.12.175 via Emacs package manger (ths gives me ~\emacs-29.emacs.d\elpa\tree-sitter-langs-0.12.175\bin\python.dll )
• restart emacs via runemacs -q
• open py file
• call python-ts-mode

Result: it looks for libtree-sitter-python.dll

python-ts-mode calls (treesit-ready-p 'python) which throws an error because (treesit-language-available-p lang t) fails

treesit-language-available-p is a C function

This is tree-sitter.el and not the built-in treesit.el. 🤔 I think you are looking for https://github.com/renzmann/treesit-auto.

Thanks. I tried it but could not get it working. Will try again.

Maybe add some info on your frontpage/READ about this

I am trying to upgrade to Emacs 29 (windows) and find it difficult to understand treesit support

[vjohansen]

treesit-auto tries to compile with cc on windows so that does not work and a substitute for a package precompiled DLLs

  Warning (treesit): Error encountered when installing language grammar: (file-missing Searching for program No such file or directory cc)

[jcs090218]

tree-sitter.el is not the same as treesit.el. You should open a bug report on their repo!

Maybe add some info on your frontpage/READ about this

I agree. This can be quite confusing for people who are new to Emacs.
