All equations are converted to html when the book is compiled, which allows for faster page rendering.
First, install the crate
cargo install mdbook-katex
Then, add the KaTex preprocessor to your book.toml file
toml
[preprocessor.katex]
command = "mdbook-katex"
Once this is done, you can use KaTex expressions within your .md files, using $
and $$
delimiters.
```md
Here is an inline example, $ \pi(\theta) $, and here is an equation:
$$ \nabla f(x) \in \mathbb{R}^n $$ ```
Only KaTex macros with no argument are supported for now. They must be specified in a txt
file, according to the following pattern
txt
\grad:{\nabla}
\Rn:{\mathbb{R}^n}
Then, change the preprocessor command to tell it where the macros are located
toml
[preprocessor.katex]
command = "mdbook-katex --macros=./macros.txt"
```
Here is an inline example, $ \pi(\theta) $, and here is an equation:
$$ \grad f(x) \in \Rn $$```
