Sphinx注释自动生成Python文档

Sphinx自动生成Python文档

sphinx是一种基于Python的文档工具，它可以令人轻松的撰写出清晰且优美的文档，由Georg Brandl在BSD许可证下开发。新版的Python3文档就是由sphinx生成的，其他诸如机器学习库scikit-learn、Jupyter Notebook也是基于sphinx生成的。

安装sphinx包

pip install sphinx

尝试

> Separate source and build directories (y/n) [n]: y > Project name: sphinx_test > Author name(s): liyu > Project release []: 1.0 > Project language [en]: zh_CN 或 回车默认英文

5.在doc/source/conf.py指定项目代码路径

import os import sys sys.path.insert(0, os.path.abspath('../../src'))

6.在doc/source/conf.py修改扩展extensions，添加功能【包括注释中的文档】、【支持NumPy和Google风格】、【包括测试片段】、【链接到其他项目的文档】、【TODO项】、【文档覆盖率统计】、【通过javascript呈现数学】

extensions = [ 'sphinx.ext.autodoc', 'sphinx.ext.napoleon', 'sphinx.ext.doctest', 'sphinx.ext.intersphinx', 'sphinx.ext.todo', 'sphinx.ext.coverage', 'sphinx.ext.mathjax', ]

8.生成HTMLmake html

9.打开build/html/google_style

重新生成文档

项目代码未变更

在doc下执行命令make clean

在doc下执行命令make html（直接也行）

项目代码已变更

删除doc/build下的所有文件夹

删除doc/source下除index.rst的所有.rst文件

在doc下执行命令sphinx-apidoc -o source …/src/

在doc下执行命令make html

切换主题

1.安装主题pip install sphinx_rtd_theme

2.修改doc/source/conf.py的html_theme

html_theme = 'sphinx_rtd_theme'

3.重新生成

主题可以参考
