hatch-sphinx 0.0.2

A plugin for Hatch for building documentation with Sphinx

Hatch Sphinx Plugin

A plugin for Hatch that allows you to build documentation with Sphinx and include the output in your package distributions.

Installation

hatch-sphinx is a plugin for the hatchling build system, so to use it in your project you'll need to to be using that build-backend. You can add hatch-sphinx to your project's pyproject.toml file as a build-system requirement:

[build-system]
requires = ["hatchling", "hatch-sphinx"]
build-backend = "hatchling.build"

Standard Python package builders (pip install <package>, python -m build, hatchling build, ...) will install the hatch-sphinx package for you into the build environment. (Or at least, they will do so once hatch-sphinx is uploaded to PyPI!)

Usage

The set of Sphinx build steps needed by your project are configured in the the [[tool.hatch.build.targets.wheel.hooks.sphinx.tools]] tables in your pyproject.toml file. You can repeat this table multiple times to run different tools (e.g. sphinx-apidoc and then sphinx-build).

Which tool is being run is configured via the tool configuration key. The known values are build, apidoc, custom, and the different configuration keys they support are listed below

Common options

Key	Default	Description
tool	required	Select the tool to be run build, apidoc or custom
doc_dir	"doc", "docs", "." (first existing)	The 'base' of the Sphinx documentation tree; set as the working directory prior to invoking any tool.
out_dir	"output"	The directory the tool outputs will be placed into, relative do doc_dir; created if it doesn't exist and deleted on clean.
work_dir	"."	The directory to run the commands in. All artifact patterns are relative to this directory.
sphinx_opts	""	Any additional options to be sent to the tool.
environment	{}	Dictionary of environment settings passed to the tool.

Tool apidoc options

Key	Default	Description
tool	required	apidoc
depth	3	API depth to be included (-d 3 option).
private	false	Include private members in documentation (--private option).
separate	true	Make a separate rst file per module (--separate option).
header	None	Header for documentation (-H header option).
source	"."	Source code to be included in the API docs.
tool_apidoc	["python", "-m", "sphinx.ext.apidoc"	Command to run as a list of strings

Tool build options

Key	Default	Description
tool	required	build
format	"html"	Output format for documentation (-b html option).
warnings	false	Treat warnings as errors (--warnings option).
keep_going	false	Continue after warnings rather exiting immediately (--keep-going option).
source	"."	Source code to be included in the docs.
tool_build	["python", "-m", "sphinx", "build"	Command to run as a list of strings

Tool custom options

Key	Default	Description
tool	required	custom
commands	required	List of commands to be executed; the magic string {python} is replaced with current interpreter (sys.executable). Each command can be a list of strings (preferred) or a single string.
shell	false	Whether to run the command via the shell (i.e. the shell parameter for subprocess.run) which permits wildcard expansion and scripting; note that the command cannot be a list of strings in shell=true mode. The standard warnings from subprocess.run to avoid using the shell apply here too.
expand_globs	false	Whether to expand globs in the command arguments.

Note that not all combinations of shell=true, expand_globs=true and the individual command being a single string are supported. The recommended configuration is to use shell=false and each command as a list, with expand_globs=true if wildcard expansion is needed.

Examples

A sample configuration for generating the API docs and then running Sphinx

[[tool.hatch.build.targets.wheel.hooks.sphinx.tools]]
tool = "apidoc"
source = "../src/mymodule"
out_dir = "source/api"
depth = 4
header = "MyModule API Documentation"

[[tool.hatch.build.targets.wheel.hooks.sphinx.tools]]
tool = "build"
format = "html"
source = "source"
out_dir = "build"

[[tool.hatch.build.targets.wheel.hooks.sphinx.tools]]
tool = "custom"
out_dir = "build"
shell = false
expand_globs = true
commands = [
  [ "ls", "-l", "*.py" ],
  "ls -l *.py",
  [ "{python}", "-c", "import shutil; shutil.copytree('foo', 'bar')"],
]

Notes

• The examples above are focusing on the wheel stage but it is possible to build the docs in the sdist stage instead if desired.
• The output directory is deleted in the clean step if used (e.g. hatchling build --clean)

To-do list

• support a make tool for Makefile based invocation of Sphinx
• add option to allow commands to exit uncleanly
