===========
codemetrics
===========

Mine your SCM for insight on your software. A work of love
inspired by `Adam Tornhill`_'s books.

Code metrics is a simple Python module that leverage pandas and your source control management (SCM) tool togenerate
insight on your code base.

- pandas_: for data munching.
- lizard_: for code complexity calculation.
- cloc.pl (script): for line counts from cloc_
- For now, only Subversion and git are supported.


Installation
------------

To install codemetrics into a uv environment:

::

  uv venv
  uv pip install codemetrics



Usage
-----

This is a simple tool that makes it easy to retrieve information from your
Source Control Management (SCM) repository and hopefully gain insight from it.

::

  import codemetrics as cm
  import cm.git

  project = cm.GitProject('path/to/project')
  loc_df = cm.get_cloc(project, cloc_program='/path/to/cloc')
  log_df = cm.get_log(project)
  ages_df = cm.get_ages(log_df)


To retrieve the number of lines changed by revision with Subversion:

::

  import codemetrics as cm
  import cm.git

  project = cm.SvnProject('path/to/project')
  log_df = cm.get_log(project).set_index(['revision', 'path'])
  log_df.loc[:, ['added', 'removed']] = log_df.reset_index().\
                                           groupby('revision').\
                                           apply(cm.svn.get_diff_stats, chunks=False)

See `module documentation`_ for more advanced functions or the `example notebook`_ where codemetrics is applied to pandas.

There is also an `example notebook`_ running codemetrics on the pandas code base, and
the `example html export`_ of that notebook output (some features are missing like
the display of file names when hovering on the circles).

Development
-----------

Install `uv <https://docs.astral.sh/uv/getting-started/installation/>`_, then run::

  uv sync --locked
  uv run --locked pytest

Dependencies are declared in ``pyproject.toml`` and pinned in ``uv.lock``.
Use ``uv sync --locked --group docs`` for documentation dependencies or
``uv sync --locked --group notebooks`` for notebooks. See CONTRIBUTING.rst
for the full workflow.
