ARCHIVED SINCE 2021-05-01

The documentation is now hosted in the doc folder of the qutip/qutip repository.

As of May 2021, this is no longer the main repository for QuTiP documentation development, but is preserved to avoid breaking old links. Please submit all new issues and pull requests there, instead.

The rest of this readme and repository are left as-is.

Repository for QuTiP documentation

This repository contains the source files for the QuTiP documentation.

For pre-built documentation, see http://www.qutip.org/documentation.html

Building

The main Python requirements for the documentation are sphinx, sphinx-gallery, sphinx_rtd_theme, numpydoc and ipython. You should build or install the version of QuTiP you want to build the documentation against in the same environment. You will also need a sensible copy of make, and if you want to build the LaTeX documentation then also a pdflatex distribution. As of 2021-04-20, the conda recipe for sphinx_rtd_theme is rather old compared to the pip version, so it's recommended to use a mostly pip-managed environment to do the documentation build.

The simplest way to get a functional build environment is to use the requirements.txt file in this repository, which completely defines a known-good pip environment (tested on Python 3.8, but not necessarily limited to it). If you typically use conda, the way to do this is

$ conda create -n qutip-doc-build python=3.8
$ conda activate qutip-doc-build
$ pip install -r /path/to/qutip-doc/requirements.txt

You will also need to build or install the main QuTiP library in the same environment. If you simply want to build the documentation without editing the main library, you can install a release version of QuTiP with pip install qutip. Otherwise, refer to the main repository for the current process to build from source. You need to have the optional QuTiP dependency Cython to build the documentation, but this is included in this repository's requirements.txt so you do not need to do anything separately.

After you have done this, you can effect the build with make. The targets you might want are html, latexpdf and clean, which build the HTML pages, build the PDFs, and delete all built files respectively. For example, to build the HTML files only, use

$ make html

Note (2021-04-20): the documentation build is currently broken on Windows due to incompatibilities in the main library in multiprocessing components.

Writing User Guides

The user guide provides an overview of QuTiP's functionality. The guide is composed of individual reStructuredText (.rst) files which each get rendered as a webpage. Each page typically tackles one area of functionality. To learn more about how to write .rst files, it is useful to follow the Sphinx Guide.

The documentation build also utilizes a number of Sphinx Extensions including but not limited to doctest , autodoc , sphinx gallery , plot . Additional extensions can be configured in the conf.py file.

Tests can also be run on examples in the documentation using the doctest extension and plots are generated using the plot directive. For more specific guidelines on how to incorporate code examples into the guide, refer to (insert reference).
