Building the Documentation

This document describes how to build Nalu’s documentation. The documentation is based on the use of Doxygen, Sphinx, and Doxylink. Therefore we will need to install these tools as well as some extensions of Sphinx that are utilized.

Install the Tools

Install CMake, Doxygen, Sphinx, Doxylink, and the extensions used. Doxygen uses the dot application installed with GraphViz. Sphinx uses a combination of extensions installed with pip install as well as some that come with Nalu located in the _extensions directory. Using Homebrew on Mac OS X, this would look something like:

brew install cmake
brew install python
brew install doxygen
brew install graphviz
pip2 install sphinx
pip2 install sphinxcontrib-bibtex
pip2 install breathe
pip2 install sphinx_rtd_theme

On Linux, CMake, Python, Doxygen, and GraphViz could be installed using your package manager, e.g. sudo apt-get install cmake.

Run CMake Configure

In the Nalu repository checkout, create your own or use the build directory that already exists in the repo. Change to your designated build directory and run CMake with -DENABLE_DOCUMENTATION on. For example:

cmake -DTrilinos_DIR:PATH=$(spack location -i nalu-trilinos) \
      -DYAML_DIR:PATH=$(spack location -i yaml-cpp) \

If all of the main tools are found successfully, CMake should configure with the ability to build the documentation. If Sphinx or Doxygen aren’t found, the configure will skip the documentation.

Make the Docs

In your designated build directory, issue the command make docs which should first build the Doxygen documentation and then the Sphinx documentation. If this completes successfully, the entry point to the documentation should be in build/docs/html/index.html.
