Ken recently asked Dave for help with a Perl regular expression for parsing ISO8601 time durations. As a consequence a Perl script was written, which is available at https://gitlab.com/davmo/hprmisc/blob/master/parse_8601_duration.
In this show Ken and Dave discuss this script at some (considerable) length. Keen listeners might want to view the script as they listen. Detailed show notes describing how to put together a Perl regular expression are also available.
Unfortunately some of the line numbers in the script referred to in the show are now incorrect since Dave could not stop himself updating it.
For detailed show notes on how Dave created the script see:
