ESPnet document generation

Install

We use sphinx to generate HTML documentation.

# Clean conda env for docs
$ cd <espnet_root>
$ conda create -p ./envs python=3.10
$ conda activate ./envs

# Requirements
$ pip install -e ".[all]"
$ pip install -e ".[doc]"
$ conda install conda-forge::ffmpeg
$ conda install conda-forge::nodejs==22.6.0

# (Optional requirement) To use flake8-docstrings
$ pip install -U flake8-docstrings

If you used the above clean conda environment, you have write your own . tools/activate_python.sh. The example will be:

#!/usr/bin/env bash

# You might check $CONDA_EXE to find the <conda_root>
. <conda_root>/miniconda/etc/profile.d/conda.sh && conda activate <espnet_root>/envs

Style check using flake8-docstrings

You can check that your docstring style is correct by ci/test_flake8.sh using flake8-docstrings. Note that many existing files have been added to the black list in the script to avoid this check by default. You can freely remove files that you wanna improve.

# in ci/test_flake8.sh

# you can improve poorly written docstrings from here
flake8_black_list="\
espnet/__init__.py
espnet/asr/asr_mix_utils.py
espnet/asr/asr_utils.py
espnet/asr/chainer_backend/asr.py
...
"

# --extend-ignore for wip files for flake8-docstrings
flake8 --extend-ignore=D test utils doc ${flake8_black_list}

# white list of files that should support flake8-docstrings
flake8 espnet --exclude=${flake8_black_list//$'\n'/,}

DO NOT ADD NEW FILES TO THIS BLACK LIST!

Generate HTML

You can generate and test the webpage using sphinx Makefile.

$ cd <espnet_root>
$ ./ci/doc.sh
$ npm run docs:dev

Deploy

When your PR is merged into master branch, our CI will automatically deploy your sphinx html into https://espnet.github.io/espnet/.
