I have a Regex that works correctly in tests but not when my run my app. No idea what is going on. Here is the regex expression: Regex.scan(~r/^\[([a-z].*)\].--.(.*).--/msU, text) .
Here is the string I apply it to:
[quote]
--
foo, bar
baz
--
fdfd
The correct scan result is
# [quote]
# --
# foo, bar
# baz
# --
# fdfd
["[quote]\n--\nfoo, bar\nbaz\n--",
"quote",
"foo, bar\nbaz"]
This is what I get using the regex tester at elixre.uk and also when I run tests with mix test ... However, when I use the above regex expression in my app, the result is an empty list – the regex recognizes nothing. What to do?

Your regular expression fails for me if I put windows line endings in the string (
"\r\n") instead of Linux ones ("\n"). The optionThis is, because
.does match only\rthen, after that the regex demands to get a-but there is\n, so it fails.So you have 3 options:
(?:\r|\n|\r\n), but the output needs to be cleaned up as well.jxxcarlson
Thank you! I choose your suggested option (2). Simple and works like a charm.
