Syntax highlighting in Quartz is completely done at build-time. This means that Quartz only ships pre-calculated CSS to highlight the right words so there is no heavy client-side bundle that does the syntax highlighting.
|
|||
|
|
|
|||
|
|
And, unlike some client-side highlighters, it has a full TextMate parser grammar instead of using Regexes, allowing for highly accurate code highlighting.
|
|||
|
|
|
|||
|
|
In short, it generates HTML that looks exactly like your code in an editor like VS Code. Under the hood, it's powered by [Rehype Pretty Code](https://rehype-pretty-code.netlify.app/) which uses [Shiki](https://github.com/shikijs/shiki).
|
|||
|
|
|
|||
|
|
> [!warning]
|
|||
|
|
> Syntax highlighting does have an impact on build speed if you have a lot of code snippets in your notes.

## Formatting
|
|||
|
|
|
|||
|
|
Text inside `backticks` on a line will be formatted like code.
|
|||
|
|
|
|||
|
|
````
|
|||
|
|
```ts
|
|||
|
|
export function trimPathSuffix(fp: string): string {
|
|||
|
|
fp = clientSideSlug(fp)
|
|||
|
|
let [cleanPath, anchor] = fp.split("#", 2)
|
|||
|
|
anchor = anchor === undefined ? "" : "#" + anchor
|
|||
|
|
|
|||
|
|
return cleanPath + anchor
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
````
|
|||
|
|
|
|||
|
|
```ts
|
|||
|
|
export function trimPathSuffix(fp: string): string {
|
|||
|
|
fp = clientSideSlug(fp)
|
|||
|
|
let [cleanPath, anchor] = fp.split("#", 2)
|
|||
|
|
anchor = anchor === undefined ? "" : "#" + anchor
|
|||
|
|
|
|||
|
|
return cleanPath + anchor
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Titles
|
|||
|
|
|
|||
|
|
Add a file title to your code block, with text inside double quotes (`""`):
|
|||
|
|
|
|||
|
|
````
|
|||
|
|
```js title="..."
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
````
|
|||
|
|
|
|||
|
|
```ts title="quartz/path.ts"
|
|||
|
|
export function trimPathSuffix(fp: string): string {
|
|||
|
|
fp = clientSideSlug(fp)
|
|||
|
|
let [cleanPath, anchor] = fp.split("#", 2)
|
|||
|
|
anchor = anchor === undefined ? "" : "#" + anchor
|
|||
|
|
|
|||
|
|
return cleanPath + anchor
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Line highlighting
|
|||
|
|
|
|||
|
|
Place a numeric range inside `{}`.
|
|||
|
|
|
|||
|
|
````
|
|||
|
|
```js {1-3,4}
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
````
|
|||
|
|
|
|||
|
|
```ts {2-3,6}
|
|||
|
|
export function trimPathSuffix(fp: string): string {
|
|||
|
|
fp = clientSideSlug(fp)
|
|||
|
|
let [cleanPath, anchor] = fp.split("#", 2)
|
|||
|
|
anchor = anchor === undefined ? "" : "#" + anchor
|
|||
|
|
|
|||
|
|
return cleanPath + anchor
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Word highlighting
|
|||
|
|
|
|||
|
|
A series of characters, like a literal regex.
|
|||
|
|
|
|||
|
|
````
|
|||
|
|
```js /useState/
|
|||
|
|
const [age, setAge] = useState(50);
|
|||
|
|
const [name, setName] = useState('Taylor');
|
|||
|
|
```
|
|||
|
|
````
|
|||
|
|
|
|||
|
|
```js /useState/
|
|||
|
|
const [age, setAge] = useState(50)
|
|||
|
|
const [name, setName] = useState("Taylor")
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Line numbers
|
|||
|
|
|
|||
|
|
Syntax highlighting has line numbers configured automatically. If you want to start line numbers at a specific number, use `showLineNumbers{number}`:
|
|||
|
|
|
|||
|
|
````
|
|||
|
|
```js showLineNumbers{number}
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
````
|
|||
|
|
|
|||
|
|
```ts showLineNumbers{20}
|
|||
|
|
export function trimPathSuffix(fp: string): string {
|
|||
|
|
fp = clientSideSlug(fp)
|
|||
|
|
let [cleanPath, anchor] = fp.split("#", 2)
|
|||
|
|
anchor = anchor === undefined ? "" : "#" + anchor
|
|||
|
|
|
|||
|
|
return cleanPath + anchor
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Escaping code blocks
|
|||
|
|
|
|||
|
|
You can format a codeblock inside of a codeblock by wrapping it with another level of backtick fences that has one more backtick than the previous fence.
|
|||
|
|
|
|||
|
|
`````
|
|||
|
|
````
|
|||
|
|
```js /useState/
|
|||
|
|
const [age, setAge] = useState(50);
|
|||
|
|
const [name, setName] = useState('Taylor');
|
|||
|
|
```
|
|||
|
|
````
|
|||
|
|
`````
|
|||
|
|
|
|||
|
|
## Customization

|||
|
|
|
|||
|

Syntax highlighting is a functionality of the [[SyntaxHighlighting]] plugin. See the plugin page for customization options.
