codly.sublang

Assigns a syntax-highlighting language to an inclusive range of source lines in a code block.

Signature

codly.sublang(
  start: int,
  end: int,
  lang: str,
)

All fields are required and named. The value can also be supplied as a dictionary.

Fields

Behavior

Pass one or more codly.sublang values in the sublangs argument to codly.new. start must be positive and end at least start; invalid ranges raise an error. Lines outside the ranges keep the raw block’s language. Ranges may also be supplied as dictionaries with the same three fields.

Example: Basic Usage
