A Rust pre-processor for mdBook, converting Latex equations to HTML at compile time. This preprocessor uses the Katex crate; see this page for the list of supported Latex functions.

Basic Usage

First, install the crate

cargo install mdbook-katex

Then, add the KaTex preprocessor to your book.toml file

[preprocessor.katex]

Once this is done, you can use KaTex expressions within your .md files, using $ and $$ delimiters. Use \$ for a regular dollar symbol.

# Chapter 1

Here is an inline example, $ \pi(\theta) $, 

An equation:

$$ \nabla f(x) \in \mathbb{R}^n $$

And a regular \$ symbol.

Macros

Macros with no arguments are supported. They must be defined in a .txt file, according to the following pattern

\grad:{\nabla}
\Rn:{\mathbb{R}^n}

Then, specify the macros location in book.toml

[preprocessor.katex]
macros = "path/to/macros.txt"

You can now use these macros in any .md file.

# Chapter 1

$$ \grad f(x) \in \Rn $$
