Package: tree-sitter-languages
Binary Python wheels for all tree sitter languages.py-tree-sitteris a fantastic library that provides Python bindings for the
even more fantastictree-sitterparsing library.py-tree-sitter-languagesprovides binary Python wheels for all tree sitter
languages. The binary wheels remove the need to download and compile support
for individual languages.Installpip install tree_sitter_languagesSource installs are not supported. To see how the binary wheels are built, look
at:setup.py— Python package setup.repos.txt— Text file that contains a list of included language repositories and their commit hashes.build.py— Python script to download and build the language repositories..github/workflows/release.yml— GitHub action to invokecibuildwheeland
release to PyPI.Usagefromtree_sitter_languagesimportget_language,get_parserlanguage=get_language('python')parser=get_parser('python')That’s the whole API!Refer topy-tree-sitterfor the language and parser API. Notice theLanguage.build_library(...)step can be skipped! The binary wheel includes
the language binary.DemoWant to know something crazy? Python lacks multi-line comments. Whhaaa!?!It’s really not such a big deal. Instead of writing"""

"""Simply write# My awesome# multi-line# comment.So multi-line comments are made by putting multiple single-line comments in
sequence. Amazing!Now, how to find all the strings being used as comments?Start with some example Python codeexample="""

"""Notice a couple things:Python has module, class, and function docstrings that bare a striking
resemblance to the phony string comments.Python supports single-quoted, double-quoted, triple-single-quoted, and
