Sphinx在项目中部署应用

一、将安装的Sphinx发布

创建FindSphinx.cmake，这个名字只能是这个

find_program(SPHINX_EXECUTABLE NAMES sphinx-build
    HINTS
    $ENV{SPHINX_DIR}
    HINTS ${SPHINX_ROOT}/bin
    PATH_SUFFIXES bin
    DOC "Sphinx documentation generator"
)

include(FindPackageHandleStandardArgs)

find_package_handle_standard_args(Sphinx DEFAULT_MSG
    SPHINX_EXECUTABLE
)

mark_as_advanced(
    SPHINX_EXECUTABLE
)

二、编写构建函数

函数的名字为build_sphinx，参数为args,源文件所在的路径

function(build_sphinx args)
# 将第一步创建cmake文件的路径添加到CMAKE_MODULE_PATH
list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/cmake")
# 因为第一步，这一步才能找到
find_package(Sphinx REQUIRED COMPONENTS breathe)
if (SPHINX_FOUND)
	# 网页显示的一些静态资源所在文件夹
    set(SPHINX_DOC_STATIC_DIR ${CMAKE_CURRENT_LIST_DIR}/docs/manual/static)
    # 可配置的配置文件所在的路径
    set(SPHINX_DOC_CONF_FILE ${CMAKE_CURRENT_LIST_DIR}/docs/manual/conf.py.in)
    configure_file(${SPHINX_DOC_CONF_FILE} ${CMAKE_CURRENT_BINARY_DIR}/conf.py @ONLY)

    add_custom_target(pos_docs ALL
        COMMAND 
            ${SPHINX_EXECUTABLE}
            -q
            -j 8
            -b html
            -c ${CMAKE_CURRENT_BINARY_DIR}
            -d ${CMAKE_CURRENT_BINARY_DIR}/doctrees
            # ${CMAKE_CURRENT_SOURCE_DIR}/docs
            ${args}    # 待编译的源文件的路径
            ${CMAKE_CURRENT_BINARY_DIR}/manual/html  # 编译后生成文档所在的路径            
        COMMENT "HTML doxygen documentation"
        DEPENDS ${DOXYGEN_INDEX_FILE} ${CMAKE_CURRENT_BINARY_DIR}/conf.py
        VERBATIM
    )
    set(CMAKE_INSTALL_MESSAGE NEVER) 
else (SPHINX_FOUND)
    message("Sphinx need to be installed to generate the manual documentation")
endif(SPHINX_FOUND)

endfunction(build_sphinx args)

三、配置文件和静态资源文件

color.css

@import url("default.css");

.red {
    color: red;
}
.blue {
    color: blue;
}

roles.include

.. |br| raw:: html

  <br/>

.. |pre| raw:: html
   
  <pre/>

style.css

.wy-nav-content {
    max-width: none;
}

conf.py.in

# Configuration file for the Sphinx documentation builder.
#
# This file only contains a selection of the most common options. For a full
# list see the documentation:
# https://www.sphinx-doc.org/en/master/usage/configuration.html

# -- Path setup --------------------------------------------------------------

# If extensions (or modules to document with autodoc) are in another directory,
# add these directories to sys.path here. If the directory is relative to the
# documentation root, use os.path.abspath to make it absolute, like shown here.
#
# import os
# import sys
# sys.path.insert(0, os.path.abspath('.'))


# -- Project information -----------------------------------------------------

project = 'Dynamic'
copyright = '2022, dynamic'
author = 'dynamic'


# -- General configuration ---------------------------------------------------

# Add any Sphinx extension module names here, as strings. They can be
# extensions coming with Sphinx (named 'sphinx.ext.*') or your custom
# ones.

extensions = [
    'sphinx.ext.graphviz',
    'myst_parser',
]

# Add any paths that contain templates here, relative to this directory.
templates_path = ['templates']

# List of patterns, relative to source directory, that match files and
# directories to ignore when looking for source files.
# This pattern also affects html_static_path and html_extra_path.
exclude_patterns = ['build', 'Thumbs.db', '.DS_Store']


# -- Options for HTML output -------------------------------------------------

# The theme to use for HTML and HTML Help pages.  See the documentation for
# a list of builtin themes.
#
import sphinx_rtd_theme
html_theme = "sphinx_rtd_theme"

master_doc = 'index'
man_pages = [
    (master_doc, 'XX', u'XX 使用指南',
     [author], 1)
]

pygments_style = 'sphinx'

# Add any paths that contain custom static files (such as style sheets) here,
# relative to this directory. They are copied after the builtin static files,
# so a file named "default.css" will overwrite the builtin "default.css".
html_static_path = ['@SPHINX_DOC_STATIC_DIR@']
html_css_files=['color.css', 'style.css']

source_suffix = {
    '.rst': 'restructuredtext',
    '.txt': 'markdown',
    '.md': 'markdown',
}

source_parsers = {
    '.md': 'recommonmark.parser.CommonMarkParser',
}

pdf_documents = [('index', u'rst2pdf', u'Sample rst2pdf doc', u'Your Name'),]

四、在CMakeLists.txt调用

include (cmake/build_sphinx.cmake)
build_sphinx(${CMAKE_SOURCE_DIR}/docs/manual/src/)

五、编译完成后进行安装

install(DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/manual/html/
    DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}/../docs/manual/
)

六、编写相应文档

具体的目录结构如下图所示：

对该工具了解有限，在实际项目按照以上的方法可以实现自己的需求，并不一定适应于所有的项目，仅供参考。具体的rst语法在下一篇文章中做详细的整理
