[Expectperl-discuss] Expect.pm broken at the moment, regexp end-of-string anchoring does not work.

[<ple...@gm...>]

Hi,

there are reports that regexp matching with an end-of-string anchor do
not work, they leave a residue in the 'after" match buffer, corrupting
subsequent expect calls.

Please find examples of these reports below.

What is the most efficient way to bring this issue and the various
proposed patches to the maintainer's attention?

Kind regards,

Karl.

https://github.com/jacoby/expect.pm/issues/10
"my $string = "test\r\ntest-end-test\r\nend";
my $pattern = qr/^end$/m;
(...)
String:
test
test-end-test
end

Output:
Before: test
test-
After: -test
end

Expected output:
Before: test
test-end-test
After:"

According to bisect, this is the first bad commit:
7ee4816fd4a560ff0b9ee14c3f273222b215a8d3 Which did mess with
before/match/after. I've copied Gabor Szabo who authored that commit.
It was in 2014 and he may or may not be able to help you now..."
