• Install sphinx>=2.0 and related dependencies by:

  pip3 install -U sphinx sphinx-autodoc-typehints sphinx-serve sphinxcontrib-jupyter nbsphinx jieba
  pip3 install git+https://github.com/pandas-dev/pydata-sphinx-theme.git@master
  

• reStructuredText (RST) is used for document writing. HTML files can be generated from the RST files for document visualization.

  For more information about RST, please visit https://sphinx-doc-zh.readthedocs.io/en/latest/rest.html.

1. Make sure you have installed MegEngine.

   pip3 install megengine -f https://megengine.org.cn/whl/mge.html

2. Run gen_python_docs/gendoc.sh to generate HTML files. The script accepts the previous python site-packages directory as the argument. Default value is ~/.local/lib/python3.6/site-packages. Note that the RST files generated from python docstring are put under source/autogen.

   ./gen_python_docs/gendoc.sh ~/.local/lib/python3.6/site-packages

3. Start local sphinx service by:

   sphinx-serve -b build -p 8000

• How documents are generated for python codes

  1. Write comments following docstring rules.
  2. Run sphinx tool to generate RST files from python docstring.
  3. Generate HTML files from RST.

  Refer to gen_python_docs/gendoc.sh for more details.

• Example python docstring: see gen_python_docs/example/example.py.

API docstring also contains examples written by doctest. Run the tests by

gen_python_docs/gendoc.sh ~/.local/lib/python3.6/site-packages
sphinx-build -b doctest source build/doctest

If all tests are passed, you shall see the following similar printouts:

Doctest summary
===============
   16 tests
    0 failures in tests
    0 failures in setup code
    0 failures in cleanup code
build succeeded.

Otherwise, please fix any failed test or warning.
