Contributing to KWSys
*********************

Patches
=======

KWSys is kept in its own Git repository and shared by several projects
via copies in their source trees.  Changes to KWSys should not be made
directly in a host project, except perhaps in maintenance branches.

KWSys uses `Kitware's GitLab Instance`_ to manage development and code review.
To contribute patches:

#. Fork the upstream `KWSys Repository`_ into a personal account.
#. Base all new work on the upstream ``master`` branch.
#. Run ``./SetupForDevelopment.sh`` in new local work trees.
#. Create commits making incremental, distinct, logically complete changes.
#. Push a topic branch to a personal repository fork on GitLab.
#. Create a GitLab Merge Request targeting the upstream ``master`` branch.

Once changes are reviewed, tested, and integrated to KWSys upstream then
copies of KWSys within dependent projects can be updated to get the changes.

Code Style
==========

We use `clang-format`_ version **3.8** to define our style for C++ code in
the KWSys source tree.  See the `.clang-format`_ configuration file for
our style settings.  Use the `clang-format.bash`_ script to format source
code.  It automatically runs ``clang-format`` on the set of source files
for which we enforce style.  The script also has options to format only
a subset of files, such as those that are locally modified.

We do not require any formal copyright assignment or contributor license
agreement.  Any contributions intentionally sent upstream are presumed
to be offered under terms of the OSI-approved BSD 3-clause License.
