math_demo

This is a small demo module showing how pdoc renders $\LaTeX$ when invoked as pdoc --math!

Using Math in Docstrings

Note that docstrings work like regular strings, so backslashes are treated as escape characters. You can either escape a backslash with a second backslash:

def foo():
    """docstring with $\\frac{x}{y}$."""

or prefix your docstring with an "r" so that you have a raw string where backslashes are not processed:

def foo():
    r"""raw docstring with $\frac{x}{y}$."""

Advanced Usage

pdoc uses MathJax's MathJax's in-browser renderer by default. Please note that while pdoc generally strives to be self-contained, these resources are included from MathJax's CDN. You can create a math.html.jinja2 file in your pdoc template directory to override the default implementation.
