Subject: bug#77848: 31.0.50; treesit-update-ranges: offset setting is ignored for local parsers
Date: Wed, 16 Apr 2025 21:05:13 +0200
Hello, I've noticed that when defining 'treesit-range-settings' using 
the 'treesit-range-rules helper function, such as:

(treesit-range-rules
 :embed 'markdown-inline
 :host 'clojure
 :offset '(1 . -1)
 :local t
 (clojure-ts--docstring-query '@capture))

The ':offset' setting doesn't have any effect.

After debugging the 'treesit-update-ranges' function, I noticed that 
it calls 'treesit--update-range-1', which in turn calls 
'treesit--update-ranges-local' if ':local t' is 
specified. 'treesit--update-ranges-local' does not accept offset as an 
argument, although it is mentioned in its documentation string:

> OFFSET is a cons of start and end offsets that are applied to the 
> range
> for the local parser.

This discrepancy between the documented behavior and the actual 
implementation of 'treesit--update-ranges-local' regarding the offset 
argument might be a bug.
