Generating the documentation

To generate the documentation, you first have to build it. Several packages are necessary to build the doc, you can install them with the following command, at the root of the code repository:

pip install -e ".[docs]"

Packages installed

Here's an overview of all the packages installed. If you ran the previous command installing all packages from requirements.txt, you do not need to run the following commands.

Building it requires the package sphinx that you can install using:

pip install -U sphinx

You would also need the custom installed theme by Read The Docs. You can install it using the following command:

pip install sphinx_rtd_theme

The third necessary package is the recommonmark package to accept Markdown as well as Restructured text:

pip install recommonmark

Building the documentation

Make sure that there is a symlink from the example file (in /examples) inside the source folder. Run the following command to generate it:

ln -s ../../examples/README.md examples.md

Once you have setup sphinx, you can build the documentation by running the following command in the /docs folder:

make html

A folder called _build/html should have been created. You can now open the file _build/html/index.html in your browser.

NOTE

If you are adding/removing elements from the toc-tree or from any structural item, it is recommended to clean the build directory before rebuilding. Run the following command to clean and build:

make clean && make html

---

It should build the static app that will be available under /docs/_build/html

Adding a new element to the tree (toc-tree)

Accepted files are reStructuredText (.rst) and Markdown (.md). Create a file with its extension and put it in the source directory. You can then link it to the toc-tree by putting the filename without the extension.
