math-svg: A Plugin for Pelican




Render math expressions to svg and embed them.
Installation
This plugin can be installed via:
python -m pip install pelican-math-svg

Afterwards, add the plugin to the PLUGINS list in your pelicanconf.py file, e.g.:
PLUGINS = [
"math_svg",
]

Multi-Core Rendering
To use multi-core rendering of equations (highly recommended, especially when many equations have to be rendered) change the html target in the Makefile of your pelican site to a three step process:
html:
PELICAN_MATH_SVG_DRY=True "$(PELICAN)" "$(INPUTDIR)" -o "$(OUTPUTDIR)" -s "$(CONFFILE)" $(PELICANOPTS)
pelican-math-svg render -j $(shell nproc)
"$(PELICAN)" "$(INPUTDIR)" -o "$(OUTPUTDIR)" -s "$(CONFFILE)" $(PELICANOPTS)

The first commands will execute math-svg in dry-mode and only populate the equation database without actually rendering anything.
The second command will render all missing equations in parallel.
The number of threads is specified by the -j flag, in this example all CPU cores are used.
Replace $(shell nproc) with a number to use a fixed number of cores.
The last command is the usual pelican command and produces the output files again, know including the rendered equations.
Requirements

required LaTeX tools (all included in TeX Live and possibly other LaTeX distributions):

lualatex (or another LaTeX compiler if changed in the settings, see below)
pdfcrop
dvisvgm


scour (optional)
svgo (optional)

Usage
In Markdown you can use $x$ for inline math and
$$
\int x^2
$$

for display math.
It is required to set the stroke color using the strokeonly class (this class name can be changed, see configuration options below), otherwise lines would be rendered white:
svg path.strokeonly {
color: #000;
}

To change the fill color for equations as well, thus essential changing the default color for math, specify the following additionally:
span.math svg path,
div.math svg path {
fill: #000;
}

Configuration
In your pelicanconf.py you can use the following options to tweak the behavior of the plugin:
