Erlang regex to match either the end of a line, or the end of the file

I've tried [\n$] and a few other things, but none seem to work in Erlang (even if they work on regexr). What's the right way to do this in Erlang (re:compile)?

Use (\n|$):

> re:run("foobar", "(\n|$)").
{match,[{6,0},{6,0}]}
> re:run("foo\nbar", "(\n|$)").
{match,[{3,1},{3,1}]}

That is, there are two alternatives: either match a newline, or the end of the string.
