Sphinx documentation from c/c++ doxygen doc

📺 Demo

# Installing dependencies
pip3 install sphinx shibuya breathe exhale
sudo apt-get install doxygen

# Generating documentation
cd docs
make html

You can acces it through docs/build/html/index.html.

🚀 How to use it ?

1. Generate the sphinx structure

In a first place, you need to generate the sphinx documentation using the command sphinx-quickstart inside a docs folder as below :

mkdir docs
cd docs
sphinx-quickstart --sep -l "fr" -r 1.0 .

Now your project structure should look like this

my_project/
├── docs/
│   ├── build/
│   ├── source/
│   ├── conf.py
│   ├── make.bat
│   └── Makefie
├── src
└── readme.md

2. Edit sphinx config

And lastly you need to copy the next script at the end of the conf.py file. This script add the needed configuration to allow sphinx to generate the documentation from doxygen documentation inside .h,.c,.cpp,.hpp... (You don't need to change anything in the next configuration)

extensions += ['breathe','exhale']

breathe_projects = {"My Project": "../build/_doxygen/xml"}
breathe_default_project = "My Project"

exhale_args = {
    "containmentFolder":     "./api",
    "rootFileName":          "library_root.rst",
    "doxygenStripFromPath":  "..",
    "rootFileTitle":         "Library API",
    "createTreeView":        True,
    "exhaleExecutesDoxygen": True,
    "exhaleDoxygenStdin":    "INPUT = ../../include"
}

3. Link the doc to a toctree

Now you need to link the documentation somewhere in your sphinx rst file. The best way is to go in source/index.rst and add api/library_root as an entry of the toctree.

.. toctree::
   :maxdepth: 2
   :caption: Contents:

   api/library_root

4. Now you can generate !

Inside the docs directory you can now execute make html ! You can acces it through docs/build/html/index.html.

⚠️ Warning Do not store the build folder in your remote storage, if you use git simply copy the .gitignore inside cpp-example/docs and paste it to your docs folder.
