From 8ffe8422c53e196787c6f404e4cadc7029a7fbd9 Mon Sep 17 00:00:00 2001 From: "Basil L. Contovounesios" Date: Sat, 3 Jun 2023 11:25:05 +0100 Subject: [PATCH] Minor tree-sitter cleanups * lisp/treesit.el (treesit-fontify-with-override): Fix docstring grammar. Remove redundant precondition (bug#64052). * src/treesit.c (Ftreesit_parser_set_included_ranges): Fix typo in commentary. (treesit_predicate_equal, treesit_predicate_match) (treesit_predicate_pred): Avoid fixnum roundtrip by using list_length in place of Flength. Make error messages more accurate. (treesit_eval_predicates): Quote predicate names in error message. --- lisp/treesit.el | 5 ++--- src/treesit.c | 18 +++++++++--------- 2 files changed, 11 insertions(+), 12 deletions(-) diff --git a/lisp/treesit.el b/lisp/treesit.el index 9556b315eab..a9761dbb38d 100644 --- a/lisp/treesit.el +++ b/lisp/treesit.el @@ -894,13 +894,12 @@ signals the `treesit-font-lock-error' error if that happens."
