`codly.sublang-block`

The generated element that holds one syntax-highlighted language range inside a Codly code block.

Signature

codly.sublang-block(body, idx)

Codly creates this element while rendering codly.new. In normal use, configure language ranges with the block’s sublangs field and codly.sublang, rather than constructing this element directly. Both required fields are positional in the generated element constructor.

Fields

Field	Type	Default / required	Meaning
`body`	`content`	Required, positional	Raw block used to resolve syntax styling for the sublanguage range.
`idx`	`int`	Required, positional	Zero-based index of the sublanguage configuration within the block.

Behavior

For each configured sublanguage range, Codly creates a raw block with that range’s language and stores it in body. Its display keeps the syntax highlighting while attaching per-line metadata so the block renderer can reuse it.

Example

#import "@preview/codly:2.0.0" as codly

#codly.new(
  ```sh
  > cat test.rs
  fn main() {
      println!("hello");
  }
  > exit

  ```,
  sublangs: ((start: 2, end: 4, lang: "rs"),),
)
