Binary Python wheels for all tree sitter languages (Freed-Wu PR).

==================================================
Python Bindings for Tree Sitter with All Languages
==================================================

This is a fork!
===============

It is based on `@Freed_Wu's pull request`_ which adds support for many additional
tree-sitter language parsers beyond the original.

As the package seems unmaintained, I decided to fork it based on the PR. Note that
this version may not see additional support and you should switch back to the
original once it gets going again.

The package has been renamed to avoid collision with the original.

The Windows and ARM Arch64 packages still only get the original languages, for
Windows because the extended commandline busted the `link.exe` command line length
limit, and for ARM Arch64 because the Github action uses QEMU to build on ARM,
which is slow, so the additional languages cause the Github runner to time out.

Original README
===============

Binary Python wheels for all tree sitter languages.

`py-tree-sitter`_ is a fantastic library that provides Python bindings for the
even more fantastic `tree-sitter`_ parsing library.

`py-tree-sitter-languages`_ provides binary Python wheels for all tree sitter
languages. The binary wheels remove the need to download and compile support
for individual languages.

This package is based on

.. _`py-tree-sitter-languages`: https://github.com/grantjenks/py-tree-sitter-languages
.. _`@Freed_Wu's pull request`: https://github.com/grantjenks/py-tree-sitter-languages/pull/53


Install
=======

::

   pip install tree_sitter_languages_freed_wu_pr

Source installs are not supported. To see how the binary wheels are built, look
at:

1. `setup.py` â€” Python package setup.

2. `parsers.json`, `lockfile.json` â€” Json files that contain a list of included language repositories and their commit hashes.

3. `build.py` â€” Python script to download and build the language repositories.

4. `.github/workflows/release.yml` â€” GitHub action to invoke `cibuildwheel`_ and
   release to PyPI.

.. _`cibuildwheel`: https://github.com/pypa/cibuildwheel


Usage
=====

.. code:: python

   from tree_sitter_languages_freed_wu_pr import get_language, get_parser

   language = get_language('python')
   parser = get_parser('python')

That's the whole API!

Refer to `py-tree-sitter`_ for the language and parser API. Notice the
``Language.build_library(...)`` step can be skipped! The binary wheel includes
the language binary.

Demo
====

Want to know something crazy? Python lacks multi-line comments. Whhaaa!?!

It's really not such a big deal. Instead of writing

.. code:: python

   """
   My awesome
   multi-line
   comment.
   """

Simply write

.. code:: python

   # 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 code

.. code:: python

   example = """
   #!shebang
   # License blah blah (Apache 2.0)
   "This is a module docstring."

   a = 1

   '''This
   is
   not
   a
   multiline
   comment.'''

   b = 2

   class Test:
       "This is a class docstring."

       'This is bogus.'

       def test(self):
           "This is a function docstring."

           "Please, no."

           return 1

   c = 3
   """

Notice a couple things:

1. Python has module, class, and function docstrings that bare a striking
   resemblance to the phony string comments.

2. Python supports single-quoted, double-quoted, triple-single-quoted, and
   triple-double-quoted strings (not to mention prefixes for raw strings,
   unicode strings, and more).

Creating a regular expression to capture the phony string comments would be
exceedingly difficult!

Enter `tree-sitter`_

.. code:: python

   from tree_sitter_languages_freed_wu_pr import get_language, get_parser

   language = get_language('python')
   parser = get_parser('python')

Tree-sitter creates an abstract syntax tree (actually, a `concrete syntax
tree`_) and supports queries

.. code:: python

   tree = parser.parse(example.encode())
   node = tree.root_node
   print(node.sexp())

.. _`concrete syntax tree`: https://stackoverflow.com/q/1888854/232571

Look for statements that are a single string expression

.. code:: python

   stmt_str_pattern = '(expression_statement (string)) @stmt_str'
   stmt_str_query = language.query(stmt_str_pattern)
   stmt_strs = stmt_str_query.captures(node)
   stmt_str_points = set(
       (node.start_point, node.end_point) for node, _ in stmt_strs
   )
   print(stmt_str_points)

Now, find those statement string expressions that are actually module, class,
or function docstrings

.. code:: python

   doc_str_pattern = """
       (module . (comment)* . (expression_statement (string)) @module_doc_str)

       (class_definition
           body: (block . (expression_statement (string)) @class_doc_str))

       (function_definition
           body: (block . (expression_statement (string)) @function_doc_str))
   """
   doc_str_query = language.query(doc_str_pattern)
   doc_strs = doc_str_query.captures(node)
   doc_str_points = set(
       (node.start_point, node.end_point) for node, _ in doc_strs
   )

With the set of string expression statements and the set of docstring
statements, the locations of all phony string comments is

.. code:: python

   comment_strs = stmt_str_points - doc_str_points
   print(sorted(comment_strs))
