[Message part 3 (text/plain, inline)]

1. In a temporary directory, say ~/tmp/, get latest cperl-mode.el from

https://github.com/emacs-mirror/emacs/blob/master/lisp/progmodes/cperl-mode.el
   I used the Jul-28-2025 version

https://github.com/emacs-mirror/emacs/blob/cef4302d309e26c2191821ba998518fb89fff54e/lisp/progmodes/cperl-mode.el

2. cd ~/tmp

3. emacs -Q -L .           # Using emacs 30.1

4. M-x byte-compile-file RET cperl-mode.el RET

5. C-x C-f foo.pl

   C-x h   # select all of foo.pl
   C-M-\   # indent foo.pl

Here's the indented foo.pl:

# -*- mode: cperl -*-
my $str =~ s/^
    (Field1: [^\n]+) \s*
  Field2: \s* (\S+) \s*
            //xsm;

Notice that the regexp is not indented nicely. I would expect "Field2 ..."
to be aligned under
"(Field...)":

  my $str =~ s/^
               (Field1: [^\n]+) \s*
               Field2: \s* (\S+) \s*
               //xsm;

This bug has now been fixed in the master branch.  Tests have been
added, including the example code from the report.  I am closing the
issue now.

Keep the reports coming!  There's still a lot of room for improvement
with regard to test coverage in cperl-mode.
