Line Highlighting

Highlight specific lines in code blocks.

Static Highlighting

md
```ts {2,3}
function add(
  a: Ref<number> | number,
  b: Ref<number> | number
) {
  return computed(() => unref(a) + unref(b))
}
```

Dynamic (Click-based)

Use | to separate stages:

md
```ts {2-3|5|all}
function add(
  a: Ref<number> | number,
  b: Ref<number> | number
) {
  return computed(() => unref(a) + unref(b))
}
```

Click progression: lines 2-3 → line 5 → all lines

Special Values

  • hide - Hide the code block
  • none - Show code without highlighting
  • all - Highlight all lines
md
```ts {hide|none|all}
// Hidden → No highlight → All highlighted
```
