One is http://perldoc.perl.org/perlre.html#Assertions It was Perl that invented `\b', along with many of the other conventions that spread to other implementations, e.g. `\d' for digit, a `?' suffix for non-greedy as in /<.*?>/, the otherwise invalid `?' after an open parenthesis as a gateway for further flags like the non-capturing `:' in /(.)(?:.)(.)/, etc. Larry Wall was very knowledgable of the Unix programming environment, including the various regular expression syntaxes in sed, grep, egrep, ..., and came up with a consistent almost-superset that had some nice conveniences too. > True, but if that is starting to happen, then one of the other 'rules' > was to break a monolithic program into blocks Alas, AFAIK, get_iplayer wishes to ship as a single file. -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy _______________________________________________ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer
