While we're on the subject.. is there a single regexp that can reduce an
an abitrary collection of Re's and Fwd's to a single Re: ?
I currently preprocess my incoming messages with a perl prog consisting
a long series of regexps to deal with this.
I would be nice if I could craft a couple of stripsubjectcode expressions
that would deal with this.
The regex code you use in your perl program can be used within
SubjectStripCode. MHonArc uses the value of $_ as the final
subject string after invoking SubjectStripCode.
Now, if you want some regex help on how to handle something like the
above, here is my quick stab at it:
<SubjectStripCode>
# Remove mailing list subject identifier.
s/\[sftest\]\s/;
# Remove cascading sequence of Re/Fwd: prefixes. The regex will
# keep the first prefix and discard are subsequent ones.
s/^((?:Re(?:\[\d+\])?|Fwd):\s)(?:(?:Re(?:\[\d+\])?|Fwd):\s+)+/$1/;
</SubjectStripCode>
--ewh
