Typst Syntax

Raw Blocks

This is an inline raw block class Tclass T.

This is a long inline raw block class T {}; class T {}; class T {}; class T {}; class T {}; class T {}; class T {}; class T {}; class T {};class T {}; class T {}; class T {}; class T {}; class T {}; class T {}; class T {}; class T {}; class T {};.

Js syntax highlight are handled by syntect:

class T {};

class T {};

class T {};

class T {};

Typst syntax hightlight are specially handled internally:

#let f(x) = x;

#let f(x) = x;

#let f(x) = x;

#let f(x) = x;

Equations

This part is the most important part of the syntax test since our blog is heavily math-oriented. This is a test of inline math: $𝑓 (𝑥) = 𝑥$ . And this is a test of long block math:

\begin{aligned} d_{C E}^{2} 𝑐^{𝛼} = & \frac{1}{2} 𝑓_{𝛽 𝛾}^{𝛼} [\frac{1}{2} 𝑓_{𝜌 𝜆}^{𝛽} 𝑐^{𝜌} 𝑐^{𝜆} 𝑐^{𝛾} - \frac{1}{2} 𝑓_{𝜌 𝜆}^{𝛾} 𝑐^{𝛽} 𝑐^{𝜌} 𝑐^{𝜆}] \\ = & - \frac{1}{2} 𝑓_{𝛾 𝛽}^{𝛼} 𝑓_{𝜌 𝜆}^{𝛽} 𝑐^{𝜌} 𝑐^{𝜆} 𝑐^{𝜆} \\ = & \frac{1}{12} 𝑓_{𝛽 [𝛾}^{𝛼} 𝑓_{𝜌 𝜆]}^{𝛽} 𝑐^{𝜌} 𝑐^{𝜆} 𝑐^{𝜆} \\ = & 0 . \end{aligned}

\begin{aligned} 𝑎^{2} + 𝑏^{2} = & 𝑐^{2} \\ 𝑎^{2} 𝑏^{2} = & 𝑐^{2} \end{aligned}

There is another test for the equation block from academic-homepage-typst: GRPO

{𝒥︀}_{PPO} (𝜃) = 𝔼_{(𝑞, 𝑎) \sim 𝒟︀} [min (\frac{𝜋_{𝜃 (𝑜_{𝑡} | 𝑞, 𝑜_{< 𝑡})}}{𝜋_{𝜃_{old}} (𝑜_{𝑡} | 𝑞, 𝑜_{< 𝑡})} {\hat{𝐴}}_{𝑡}, clip (\frac{𝜋_{𝜃 (𝑜_{𝑡} | 𝑞, 𝑜_{< 𝑡})}}{𝜋_{𝜃_{old}} (𝑜_{𝑡} | 𝑞, 𝑜_{< 𝑡})}, 1 - 𝜀, 1 + 𝜀) {\hat{𝐴}}_{𝑡})]

where:

$𝑟_{𝑖, 𝑡} (𝜃) = \frac{𝜋_{𝜃} (𝑜_{𝑖, 𝑡} | 𝑞, 𝑜_{𝑖, < 𝑡})}{𝜋_{𝜃_{old}} (𝑜_{𝑖, 𝑡} | 𝑞, 𝑜_{𝑖, < 𝑡})}$ is the importance sampling ratio for the $𝑖$ -th response at time step $𝑡$ .
${\hat{𝐴}}_{𝑖, 𝑡}$ is the advantage for the $𝑖$ -th response at time step $𝑡$ .
