Contributing code to Matrix
|
|
===========================
|
|
|
|
Everyone is welcome to contribute code to Matrix
|
|
(https://github.com/matrix-org), provided that they are willing to license
|
|
their contributions under the same license as the project itself. We follow a
|
|
simple 'inbound=outbound' model for contributions: the act of submitting an
|
|
'inbound' contribution means that the contributor agrees to license the code
|
|
under the same terms as the project's overall 'outbound' license - in our
|
|
case, this is almost always Apache Software License v2 (see LICENSE).
|
|
|
|
Code style
|
|
~~~~~~~~~~
|
|
|
|
All Matrix projects have a well-defined code-style - and sometimes we've even
|
|
got as far as documenting it... For instance, synapse's code style doc lives
|
|
at https://github.com/matrix-org/synapse/tree/master/docs/code_style.rst.
|
|
|
|
Please ensure your changes match the cosmetic style of the existing project,
|
|
and **never** mix cosmetic and functional changes in the same commit, as it
|
|
makes it horribly hard to review otherwise.
|
|
|
|
Attribution
|
|
~~~~~~~~~~~
|
|
|
|
Everyone who contributes anything to Matrix is welcome to be listed in the
|
|
AUTHORS.rst file for the project in question. Please feel free to include a
|
|
change to AUTHORS.rst in your pull request to list yourself and a short
|
|
description of the area(s) you've worked on. Also, we sometimes have swag to
|
|
give away to contributors - if you feel that Matrix-branded apparel is missing
|
|
from your life, please mail us your shipping address to matrix at matrix.org
|
|
and we'll try to fix it :)

In order to have a concrete record that your contribution is intentional and you
|
|
agree to license it under the same terms as the project's license, we've adopted
|
|
the same lightweight approach that the Linux Kernel
|
|
(https://www.kernel.org/doc/Documentation/SubmittingPatches), Docker
|
|
(https://github.com/docker/docker/blob/master/CONTRIBUTING.md), and many other
|
|
projects use: the DCO (Developer Certificate of Origin:
|
|
http://developercertificate.org/). This is a simple declaration that you wrote
|
|
the contribution or otherwise have the right to contribute it to Matrix::
|
|
|
|
Developer Certificate of Origin
|
|
Version 1.1
|
|
|
|
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.

|
660 York Street, Suite 102,

Everyone is permitted to copy and distribute verbatim copies of this
|
|
license document, but changing it is not allowed.

|
By making a contribution to this project, I certify that:
|
|
|
|
(a) The contribution was created in whole or in part by me and I
|
|
have the right to submit it under the open source license
|
|
indicated in the file; or
|
|
|
|
(b) The contribution is based upon previous work that, to the best
|
|
of my knowledge, is covered under an appropriate open source
|
|
license and I have the right under that license to submit that
|
|
work with modifications, whether created in whole or in part
|
|
by me, under the same open source license (unless I am
|
|
permitted to submit under a different license), as indicated
|
|
in the file; or
|
|
|
|
(c) The contribution was provided directly to me by some other
|
|
person who certified (a), (b) or (c) and I have not modified
|
|
it.
|
|
|
|
(d) I understand and agree that this project and the contribution
|
|
are public and that a record of the contribution (including all
|
|
personal information I submit with it, including my sign-off) is
|
|
maintained indefinitely and may be redistributed consistent with
|
|
this project or the open source license(s) involved.
|
|
|
|
If you agree to this for your contribution, then all that's needed is to
|
|
include the line in your commit or pull request comment::
|
|
|
|
Signed-off-by: Your Name <your@email.example.org>
|
|
|
|
...using your real name; unfortunately pseudonyms and anonymous contributions
|
|
can't be accepted. Git makes this trivial - just use the -s flag when you do
|
|
``git commit``, having first set ``user.name`` and ``user.email`` git configs
|
|
(which you should have done anyway :)
|

|
Conclusion
|
|
~~~~~~~~~~
|
|
|
|
That's it! Matrix is a very open and collaborative project as you might expect
|
|
given our obsession with open communication. If we're going to successfully
|
|
matrix together all the fragmented communication technologies out there we are
|
|
reliant on contributions and collaboration from the community to do so. So
|
|
please get involved - and we hope you have as much fun hacking on Matrix as we
|
|
do!
