In addition to its more conventional functions, the plumber can also provide easy shortcuts for common functions. The next few examples assume a program called 'web', which takes a URL to open as an argument. Given that, the following plumbing rule will turn the string 'MR:1234' into a Bugzilla search for bug 1234: ! # MRs open Bugzilla via web. ! type is text ! data matches 'MR:([0-9]+)' ! plumb to web ! plumb start web http://bugzilla.mozilla.org/show_bug.cgi?id=$1 (obviously, you should substitute "bugzilla.mozilla.org" with the Bugzilla install you're interested in). If you have multiple issue tracking systems to deal with, just give each a unique tag: ! # RT tickets open RT via web. ! type is text ! data matches 'RT:([0-9]+)' ! plumb to web ! plumb start web http://rt.example.com/Ticket/Display.html?id=$1 Now plumbing 'RT:23' will bring up issue #23 in that RT3 installation. This extends to any sort of query, of course. Make 'RFC:2325' bring up over-engineered coffee-making instructions: ! # RFC's from one of the nicer-looking repositories. ! type is text ! data matches 'RFC:([0-9]+)' ! plumb to web ! plumb start web http://rfc.sunsite.dk/rfc/rfc$1.html From our friends over at Acme-SAC, the following will search for books by ISBN. ! type is text ! data matches 'ISBN:([0-9]+)[ \-]?([0-9]+)[ \-]?([0-9]+)[ \-]?([0-9X]+)([ \-]?([0-9]+))?' ! plumb to web ! plumb start web http://lookupbyisbn.com//search.aspx?page=1&key=$1$2$3$4$6
