在 Sphinx 中创建 LaTeX 数学宏 [英] Creating LaTeX math macros within Sphinx

问题描述

我正在用 Python 编写一些数学代码并使用 Sphinx 来生成文档.我知道 Sphinx 可以处理 Python 文档字符串中的 LaTeX 代码；见 https://www.sphinx-doc.org/en/master/usage/extensions/math.html#module-sphinx.ext.mathbase.如何创建 LaTeX 宏，例如 ewcommand{cG}{mathcal{G}}，以便在 Python 文档字符串中使用?

I'm writing some mathematical code in Python and using Sphinx to produce the documentation. I know that Sphinx can handle LaTeX code in Python docstrings; see https://www.sphinx-doc.org/en/master/usage/extensions/math.html#module-sphinx.ext.mathbase. How can I create LaTeX macros, such as ewcommand{cG}{mathcal{G}}, to use in the Python docstrings?

推荐答案

啊哈，我找到了一个适用于 Sphinx pngmath 扩展的解决方案.这是 Sage(开源数学软件)使用的技巧；灵感来自 http://www.sagemath.org/doc/reference/sage/misc/latex_macros.html.

要将您自己的 Latex 宏添加到 Sphinx 文档:

To add your own Latex macros to a Sphinx document:

1) 创建一个文件，例如latex_macros.sty"，其中包含您的宏(每行一个)，然后将其放在与您的 Sphinx conf.py 文件相同的目录中；

1) Make a file, say 'latex_macros.sty', containing your macros (one per line), and put it in, say, the same directory as your Sphinx conf.py file;

2) 将以下代码添加到您的 Sphinx conf.py 文件中:

2) Add the following code to your Sphinx conf.py file:

# Additional stuff for the LaTeX preamble.
latex_elements['preamble'] = 'usepackage{amsmath}
usepackage{amssymb}
'

#####################################################
# add LaTeX macros 

f = file('latex_macros.sty')

try:
    pngmath_latex_preamble  # check whether this is already defined
except NameError:
    pngmath_latex_preamble = ""

for macro in f:
    # used when building latex and pdf versions
    latex_elements['preamble'] += macro + '
'
    # used when building html version
    pngmath_latex_preamble += macro + '
'
