# IfcOpenShell C++ API documentation This folder contains the setup to build the IfcOpenShell C++ API documentation from the source code. ## Generating the documentation Prerequisites: make sure to have [Doxygen](https://www.doxygen.nl) and [Graphviz](https://graphviz.org) installed into your `$PATH` variable. Build with the command (from within the `/docs/cpp-api` folder): ```shell $ doxygen ``` To include the current git commit hash into the build documentation, use the following command: ```shell $ PROJECT_NUMBER=$(git rev-parse --short HEAD) doxygen ``` This will extract the current commit hash in short version and sets the propper ENV variable used by doxygen. The generation of the documentation might take a while depending on your systems hardware, as it is configured to generate the Class graphs using . The resulting documentation is located unter `/cpp-api/output/html` and can be directly accessed with your browser: ```shell $ open ./output/html/index.html ```
