Variable: treesit-language-at-point-function

treesit-language-at-point-function is a buffer-local variable defined in treesit.el.gz.

Documentation

A function that returns the language at point.

This is used by treesit-language-at, which is used by various functions to determine which parser to use at point.

The function is called with one argument, the position of point.

In general, this function should call treesit-node-at with an explicit language (usually the host language), and determine the language at point using the type of the returned node.

DO NOT derive the language at point from parser ranges. It's cumbersome and can't deal with some edge cases.
