## Contributing
This library is free, and will stay free but needs your support to sustain its development. There are lots of [**new features**](roadmap.md) and maintenance to do. If you work for a company using **doctest** or have the means to do so, please consider financial support.

## Pull requests
Consider opening an issue for a discussion before making a pull request to make sure the contribution goes smoothly.
All pull requests should be made against the ```dev``` branch because the ```master``` is the stable one with the latest release.
If you're going to change something in the library itself - make sure you don't modify ```doctest/doctest.h``` because it's generated from ```doctest/parts/doctest_fwd.h``` and ```doctest/parts/doctest_impl.h``` - they get concatenated by CMake - so make sure you do a CMake build after you modify them so the ```assemble_single_header``` target gets built. Also take into consideration how the change affects the code coverage - based on the project in ```examples/all_features```. Also update any relevant examples in the ```examples``` folder.
This framework has some design goals which must be kept. Make sure you have read the [**features and design goals**](features.md) page.
If your changes also change the output of the library - you should also update the reference output for the tests or otherwise the CI builds (```travis``` and ```appveyor```) will fail when they compare the latest output to the outdated reference output (which is committed in the repository). To do this run CMake with the ```DOCTEST_TEST_MODE``` variable set to ```COLLECT``` (making the new reference output) and then run ```ctest``` and commit the changed (or newly created) ```.txt``` files in the ```test_output``` folders too. The default ```DOCTEST_TEST_MODE``` is ```COMPARE```.
Example: ```cmake -DDOCTEST_TEST_MODE=COLLECT path/to/sources && cmake --build . && ctest```
Code should be formatted with a recent-enough ```clang-format``` using the config file in the root of the repo (or I will do it...)
Testing with compilers different from GCC/Clang/MSVC (and more platforms) is something the project would benefit from.
