fontTools Developer Information
===============================
If you would like to contribute to the development of fontTools, you can clone the repository from GitHub, install the package in 'editable' mode and modify the source code in place. We recommend creating a virtual environment, using the Python 3 `venv <https://docs.python.org/3/library/venv.html>`_ module::
# download the source code to 'fonttools' folder
git clone https://github.com/fonttools/fonttools.git
cd fonttools
# create new virtual environment called e.g. 'fonttools-venv', or anything you like
python -m venv fonttools-venv
# source the `activate` shell script to enter the environment (Un*x)
. fonttools-venv/bin/activate
# to activate the virtual environment in Windows `cmd.exe`, do
fonttools-venv\Scripts\activate.bat
# install in 'editable' mode
pip install -e .
.. note::
To exit a Python virtual environment, enter the command ``deactivate``.
Testing
-------
To run the test suite, you need to install `pytest <http://docs.pytest.org/en/latest/>`__.
When you run the ``pytest`` command, the tests will run against the
installed fontTools package, or the first one found in the
``PYTHONPATH``.
You can also use `tox <https://tox.readthedocs.io/en/latest/>`__ to
automatically run tests on different Python versions in isolated virtual
environments::
pip install tox
tox
.. note::
When you run ``tox`` without arguments, the tests are executed for all the environments listed in the ``tox.ini`` ``envlist``. The Python versions that are not available on your system ``PATH`` will be skipped.
You can specify a particular testing environment list via the ``-e`` option, or the ``TOXENV`` environment variable::
tox -e py36
TOXENV="py36-cov,htmlcov" tox
Development Community
---------------------
fontTools development is ongoing in an active community of developers that includes professional developers employed at major software corporations and type foundries as well as hobbyists.
Feature requests and bug reports are always welcome at https://github.com/fonttools/fonttools/issues/
The best place for end-user and developer discussion about the fontTools project is the `fontTools gitter channel <https://gitter.im/fonttools-dev/Lobby>`_. There is also a development https://groups.google.com/d/forum/fonttools-dev mailing list for continuous integration notifications.
History
-------
The fontTools project was started by Just van Rossum in 1999, and was
maintained as an open source project at
http://sourceforge.net/projects/fonttools/. In 2008, Paul Wise (pabs3)
began helping Just with stability maintenance. In 2013 Behdad Esfahbod
began a friendly fork, thoroughly reviewing the codebase and making
changes at https://github.com/behdad/fonttools to add new features and
support for new font formats.
