Wrong highlighting of Tcl with quotes and unmatched braces inside curly braces

[d-led]

Summary

Tcl quotes and braces rules are somewhat exotic. The syntax highlighter is confusing the syntactic elements in certain constellations, i.e. expects quoted characters, where no quoting of special characters is possible, such as within curly braces { " }.

Example

set ok1 {["]"]}
set ok2 {["][]"]}
set not_ok {["]["]}
puts $ok1            ;# ["]"]
puts $ok2            ;# ["][]"]
puts $not_ok         ;# ["]["]

Wrong highlighting

Note the highlighting after not_ok. The puts lines should be highlighted normally as commands (functions)

Sublime Version

3Dev, Build 3086

Analysis

I haven't investigated further, but the confusion is probably easy to make: the contents within top-level single quotes is not subject to escapes. Thus,

puts {\"]["]}
puts {\"][\"]}

prints

\"]["]
\"][\"]

and is highlighted as follows (wrong starting from the last curly brace on the first line):

This was fixed in build 3096

My apologizes, someone added a test for that with the commit, but I missed the fact that they didn't actually fix it. I'll work on getting that corrected now.

Should be fixed by https://github.com/sublimehq/Packages/commit/f89329688ca5076ad02ea4c9710f5c21bacf17b5, which will be part of dev build 3112.

ok!

[d-led]

yay, looks good!

[d-led]

hm.. curly braces should probably not be highlighted as strings, as "everything is a string"

it should be rather:
