Commit Messages

Ensure commit messages have a single title followed by a body as necessary:

Short summary text, maximum of 72 characters. That's out to here ---->X

Longer paragraph that details the change and any logic behind needing
to make the change, other impacts, future work etc. Keeping the title
to 72 characters means it will display fully in git log and github logs.

Code formatting

To make things easier for everyone, I've adopted clang-format for keeping code consistently formatted. Ensure that your commits are clean against clang-format-3.8. Please avoid making commits which don't follow conventions, and then having a single 'reformatting' commit at the end - this makes history and blames harder to read.

Copyright / Contributor License Agreement

Any code you submit will become part of the repository and be distributed under the RenderDoc license. By submitting code to the project you agree that the code is your own work and that you have the ability to give it to the project. You also agree by submitting your code that you grant all transferrable rights to the code to the project maintainer, including for example re-licensing the code, modifying the code, distributing in source or binary forms.

Contributing & Development

There are always plenty of things to do, if you'd like to chip in! Check out the Roadmap page in the wiki for future tasks to tackle, or have a look at the issues for outstanding bugs. I'll try and tag things that seem like small changes that would be a good way for someone to get started with.

If you have a change you'd like to see make it into mainline, create a fork of renderdoc, make your changes to a branch, and open a pull request on github. You can look around for instructions on that - it's pretty simple.

We can discuss changes if there need to be any, then merge it in. Please make sure your changes are fully rebased against master when you create the pull request.

If you're tackling anything large then please contact me and post an issue so that everyone knows you're working on it and there's not duplicated effort. Specifically if you want to extend RenderDoc to a platform or API that it doesn't already support please get in touch, as there might already be code that isn't committed yet. Particularly if this is not a public API that anyone can write against.

To get started compiling there are instructions in COMPILE.md

Code of Conduct

I want to ensure that anyone can contribute to RenderDoc with only the next bug to worry about. For that reason the project has adopted the contributor covenent as a code of conduct to be enforced for anyone taking part in RenderDoc development. If you have any queries in this regard you can get in touch with me directly over email.

Code Explanation

There are several pages on the wiki explaining different aspects of how the code fits together - like how the capture-side works vs replay-side, how shader debugging works, etc.

renderdoc/ 
    Makefile                        ; The linux make file, will recurse into subdirectories to build them

                                    ; to distribute a build - assumes that exes etc are already built

Testing

At the moment the testing of any features and changes is pretty much ad-hoc. I've been working on a proper test suite that will test both API capture/replay support as well as the analysis features.

Until then, test any changes you make around the area that you've tested - if I have any particular suggestions on testing I will probably bring it up in the pull request.
