subs function should count back from the end of the string when given negative offset

Enhancement Minor Closed Declined Unassigned Phil Hagelberg Thu, 9 Dec 2010 01:28:07 -0600 Fri, 1 Mar 2013 12:46:58 -0600 Fri, 31 Dec 2010 15:39:00 -0600 Release 1.2 0 1 <p>A major strength of Clojure is consistency. If <tt>(foo X)</tt> works, then <tt>(foo Y)</tt> should work if <tt>X</tt> and <tt>Y</tt> are similar in relevant ways.</p> <p>The negative offset convenience was considered and rejected when the string library was originally moved into Clojure. In order for a feature like this to be on the table, a proposal would need to include an evaluation of all API fns that take indexes, and a plan to either make all of them handle negative indexes, or have a meaningful rule about which ones do and which ones don't. If someone is interested in doing this, please begin with a motivating problem statement in the <a href="http://dev.clojure.org/display/design/Home">Design space</a>.</p> <p>That said, this feels very low priority.</p> Approval Test Global Rank Patch Code and Test
