From: Yuan Fu Date: Thu, 27 Oct 2022 23:44:33 +0000 (-0700) Subject: Remove tree-sitter-indent's integration with cc-mode X-Git-Tag: emacs-29.0.90~1770 X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=3a4406975338eb6dad9327b5d17f67a677114e6a;p=emacs.git Remove tree-sitter-indent's integration with cc-mode Also minor improvement of tree-sitter-indent error messaging. * lisp/progmodes/js.el (js--treesit-indent-rules): Fix it so it works with the new presets (which expects regexps). (js--treesit-cc-indent-rules): Remove variable. (js-mode): Go back to js--treesit-indent-rules. * lisp/treesit.el (treesit-indent): Don't report error message when ANCHOR or OFFSET is nil: let treesit-simple-indent display the message. (treesit-simple-indent): Remove cc-mode integration. Display error message when no rules matches. --- diff --git a/lisp/progmodes/js.el b/lisp/progmodes/js.el index 89bd04b2311..f258b093f4a 100644 --- a/lisp/progmodes/js.el +++ b/lisp/progmodes/js.el @@ -3421,7 +3421,7 @@ This function is intended for use in `after-change-functions'."
