Contributing to Catch
So you want to contribute something to Catch? That's great! Whether it's a bug fix, a new feature, support for additional compilers - or just a fix to the documentation - all contributions are very welcome and very much appreciated. Of course so are bug reports and other comments and questions.
If you are contributing to the code base there are a few simple guidelines to keep in mind. This also includes notes to help you find your way around. As this is liable to drift out of date please raise an issue or, better still, a pull request for this file, if you notice that.
Branches
Ongoing development is currently on master. At some point an integration branch will be set-up and PRs should target that - but for now it's all against master. You may see feature branches come and go from time to time, too.
Directory structure
Users of Catch primarily use the single header version. Maintainers should work with the full source (which is still,
primarily, in headers). This can be found in the include folder. There are a set of test files, currently under
projects/SelfTest. The test app can be built via CMake from the CMakeLists.txt file in the root, or you can generate
project files for Visual Studio, XCode, and others (instructions in the projects folder). If you have access to CLion
that can work with the CMake file directly.
As well as the runtime test files you'll also see a SurrogateCpps directory under projects/SelfTest.
This contains a set of .cpp files that each #include a single header.
While these files are not essential to compilation they help to keep the implementation headers self-contained.
At time of writing this set is not complete but has reasonable coverage.
If you add additional headers please try to remember to add a surrogate cpp for it.
The other directories are scripts which contains a set of python scripts to help in testing Catch as well as
generating the single include, and docs, which contains the documentation as a set of markdown files.
When submitting a pull request please do not include changes to the single include, or to the version number file as these are managed by the scripts!
