|
|
|
|
The ``asttokens`` module annotates Python abstract syntax trees (ASTs) with the positions of tokens
|
|
and text in the source code that generated them.
|
|
|
|
It makes it possible for tools that work with logical AST nodes to find the particular text that
|
|
resulted in those nodes, for example for automated refactoring or highlighting.
|
|
|
|
Installation
|
|
------------
|
|
asttokens is available on PyPI: https://pypi.python.org/pypi/asttokens/::
|
|
|
|
pip install asttokens
|
|
|
|
The code is on GitHub: https://github.com/gristlabs/asttokens.
|
|
|
|
The API Reference is here: http://asttokens.readthedocs.io/en/latest/api-index.html.
|
|
|
|
Usage
|
|
-----
|
|
|
|
ASTTokens can annotate both trees built by `ast <https://docs.python.org/2/library/ast.html>`_,
|
|
AND those built by `astroid <https://github.com/PyCQA/astroid>`_.
|
|
|
|
Here's an example:
|
|
|
|
.. code-block:: python
|
|
|
|
import asttokens, ast
|
|
source = "Robot('blue').walk(steps=10*n)"
|
|
atok = asttokens.ASTTokens(source, parse=True)
|
|
|
|
Once the tree has been marked, nodes get ``.first_token``, ``.last_token`` attributes, and
|
|
the ``ASTTokens`` object offers helpful methods:
|
|
|
|
.. code-block:: python
|
|
|
|
attr_node = next(n for n in ast.walk(atok.tree) if isinstance(n, ast.Attribute))
|
|
print(atok.get_text(attr_node))
|
|
start, end = attr_node.last_token.startpos, attr_node.last_token.endpos
|
|
print(atok.text[:start] + 'RUN' + atok.text[end:])
|
|
|
|
Which produces this output:
|
|
|
|
.. code-block:: text
|
|
|
|
Robot('blue').walk
|
|
Robot('blue').RUN(steps=10*n)
|
|
|
|
The ``ASTTokens`` object also offers methods to walk and search the list of tokens that make up
|
|
the code (or a particular AST node), which is more useful and powerful than dealing with the text
|
|
directly.

Contribute
|
|
----------
|
|
|
|
To contribute:
|
|
|
|
1. Fork this repository, and clone your fork.
|
|
2. Install the package with test dependencies (ideally in a virtualenv) with::
|
|
|
|
pip install -e '.[test]'
|
|
|
|
3. Run tests in your current interpreter with the command ``pytest`` or ``python -m pytest``.
|
|
4. Run tests across all supported interpreters with the ``tox`` command. You will need to have the interpreters installed separately. We recommend ``pyenv`` for that. Use ``tox -p auto`` to run the tests in parallel.
|
|
5. By default certain tests which take a very long time to run are skipped, but they are run in CI.
|
|
These are marked using the ``pytest`` marker ``slow`` and can be run on their own with ``pytest -m slow`` or as part of the full suite with ``pytest -m ''``.
