Hi,
The following code snippet is from /usr/bin/rpl. I would like the it
to match a word, for example, "abc" in ":abc:". But the current one
would not match "abc" in ":abc:". I tried to modify it myself. Would
you please let me know what is the corrected way to do it?
Thanks,
Peng

The regular expression "\w+" will match (what might be your definition
of) a word, and in particular will match abc in :abc:. Regular
expressions have lots of other special \-sequences that might be worth
your while to read about: http://docs.python.org/lib/re-syntax.html
