Hi Peter, sorry for the _late_ reply.
It turns out that Anki stores newlines internally as , since its
display model is based on HTML. Thanks, though!

My attempt:
>>> sub = re.compile(r"\s*?(\n|$)").sub
>>> sub("", "alpha \nbeta \r\n\ngamma\n")
'alphabetagamma'
>>> sub("", "alpha \nbeta \r\n\ngamma")
'alphabetagamma'
>>> sub("", "alpha \nbeta \r\n\ngamma\t")
'alphabetagamma'

Regex to match all trailing whitespace _and_ newlines.
In the terrific Anki [1] application I am trying to remove trailing whitespace from form fields. This is my regex: [\n+\s+]$ Actually, even simplifying it to [\n] or [\r\n] is not matching any newlines! What might be the cause of this? Note that I am not entering the regex in Python code, I am entering it in a regex-supporting Find/Replace dialogue in Anki. Anki is written in Python. Thanks.
