Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
[Message part 1 (text/plain, inline)]
`ruby-forward-string' is a function used to skip past strings in Ruby
mode. Ruby supports using any non-alpha character following a "%" to
delimit a string. All of the following are valid Ruby syntax:
- %[foo bar]
- %/foo bar/
- %%foo bar%
- %^foo bar^
Currently ruby-mode can handle all of these except the last one, which
yields the following:
# Debugger entered--Lisp error: (invalid-regexp "Unmatched [ or [^")
The root of the problem is the construction of the following invalid
regexp: "[^]" (which is an incomplete negated character class).
This bug manifests itself by breaking `ruby-parse-region' in any
buffer containing a caret-delimited string. This breaks indentation,
movement commands, and even keeps Emacs from building an Imenu.
I've attached a patch which resolves the issue. Note that this patch
builds on the test suite for `ruby-forward-string' that I included in
issue #16078.

The tests are not included so far, let's continue discussing them in
