Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
From: Roman Rudakov <rrudakov <at> fastmail.com> To: bug-gnu-emacs <at> gnu.org Subject: 31.0.50; treesit.el: thing navigation functions work incorrectly with some Clojure nodes Date: Fri, 16 May 2025 17:37:23 +0200
Reproducing issues requires installing clojure-ts-mode from NonGNU
ELPA.
Considering the following Clojure expression:
#(-> (.-value (.-target %)))
The parsed syntax tree is:
(anon_fn_lit marker: # open: (
value: (sym_lit name: (sym_name))
value:
(list_lit open: (
value: (sym_lit name: (sym_name))
value:
(list_lit open: (
value: (sym_lit name: (sym_name))
value: (sym_lit name: (sym_name))
close: ))
close: ))
close: ))
Issue 1
1. Put the point on the "->" symbol
2. Execute M-x backward-up-list
Expected result: point at the # character, which is the beginning of
the anon_fn_lit node.
Actual result: point is between # and (
If I execute M-x backward-up-list again, point goes to the #
character.
Issue 2
1. Put the point after # on the opening paren.
2. Execute M-x forward-sexp
Expected result: either some error or point is moved to the matching
closing paren.
Actual result: point is before matching paren.
If the expression doesn't have any nested lists (for example #(+ 2 2))
then the same steps would signal a user error "No next step".
Issue 3
1. Put the point on the opening paren of the first nested list.
2. Execute M-x raise-sexp
Expected result: (.-value (.-target %))
Actual result: #(.-value (.-target %)))
Actual result also has unbalanced parenthesis.
Again, if the expression doesn't have any nested lists, executing
raise-sexp would signal an error:
treesit--forward-list-with-default: Scan error: "No more list to move
across"
All the issues are also applicable to nodes with metadata, for
example:
^boolean (+ 2 2)
With syntax tree:
(list_lit
meta:
(meta_lit marker: ^
value: (sym_lit name: (sym_name)))
open: (
value: (sym_lit name: (sym_name))
value: (num_lit) value: (num_lit) close: ))
