# Prettypst

## Formatter for Typst!

Before Default Style OTBS Style

```typst
= Heading
== Table or Grid
#table(
columns: (1fr, 1fr),
align: (left, right),
[a], [b],
[longer], [],
[c],
[test],
)
== Equation
$ x & = 13 y & \
& & z? \
2 y & = 13 * 2 y \
\
& \
$

Some math $c$, $d $, $ e$ and $ f_1^ pi * - 3$.
== Trailing comma and long blocks

// no trailing comma and content with only spaces
#figure(
caption: [compact],
[ Some Content ]
)

// no trailing comma and content with newline
#figure(
caption: [nested],
[
Some Content ]
)

// trailing comma and content with newline
#figure(
caption: [nested],
[
Some Content ],
)

== Linebreaks

Everything is written in content
mode is on the same line after formatting.
Maybe wanted or unwanted.
#image("image_a.png")
#image("image_b.png")

But paragraphs stay seperated!

== Label

== Nesting

#let f = (diff, content ) => {

box(width: 30%,align(center,{
content
v(diff, weak:true)
counter.display(numbering) + [ ] + caption
}))
}

== Code

#{
let x= 1 * - 3 ;
let y= 1==2 and 3==3
}
```
