LaTeX

Quartz uses Katex by default to typeset both inline and block math expressions at build time.

Syntax

Block math can be rendered by delimiting math expression with $$.

$$
f(x) = \int_{-\infty}^\infty
    f\hat(\xi),e^{2 \pi i \xi x}
    \,d\xi
$$

f (x) = \int_{- \infty}^{\infty} f \hat{(} ξ), e^{2 πi ξ x} d ξ

a = b + c = e + f

[1 a 2 b 3 c]

E ψ E f (x) = H ψ = - \frac{ℏ ^{2}}{2 m} \frac{\partial ^{2}}{\partial x ^{2}} ψ + \frac{1}{2} mω x^{2} ψ = - \frac{ℏ ^{2}}{2 m} [4 k^{2} x^{2} f (x) + 2 (- 2 k x) f^{'} (x) + f^{''} (x)] e^{- k x^{2}} + \frac{1}{2} mω x^{2} f (x) e^{- k x^{2}} ⇓ = - \frac{ℏ ^{2}}{2 m} [4 k^{2} x^{2} f (x) - 4 k x f^{'} (x) + f^{''} (x)] + \frac{1}{2} mω x^{2} f (x) = - \frac{ℏ ^{2}}{2 m} [- 4 k x f^{'} (x) + f^{''} (x)] Expanding the Hamiltonian Operator Using the ansatz ψ (x) = e^{- k x^{2}} f (x), hoping to cancel the x^{2} term Removing the e^{- k x^{2}} term from both sides Choosing k = \frac{im}{2} \frac{ω}{ℏ} to cancel the x^{2} term, via - \frac{ℏ ^{2}}{2 m} 4 k^{2} = \frac{1}{2} mω

Warn

Due to limitations in the underlying parsing library, block math in Quartz requires the $$ delimiters to be on newlines like above.

Similarly, inline math can be rendered by delimiting math expression with a single $. For example, $e^{i\pi} = -1$ produces $e^{iπ} = - 1$

There will be cases where you may have more than one $ in a paragraph at once which may accidentally trigger MathJax/Katex.

To get around this, you can escape the dollar sign by doing \$ instead.

For example:

Add the following import to the top of quartz/plugins/transformers/latex.ts (before all the other imports):

quartz/plugins/transformers/latex.ts

import "katex/contrib/mhchem"

Latex parsing is a functionality of the Latex plugin. See the plugin page for customization options.
