Defect Minor Closed Completed Tom Faulhaber Tom Faulhaber Sat, 5 Mar 2011 19:42:48 -0600 Fri, 1 Mar 2013 12:47:00 -0600 Fri, 8 Apr 2011 09:03:57 -0500 Release 1.2 Release 1.3 Release 1.3 0 0 <p>The following block of code throws an index out of range exception:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>(cl-format nil "~:(~a~)" "") </pre> </div></div> <p>Patch that fixes the issue and adds tests</p> <p>Patch works. One question: Why does cl-format print "nil" as "Nil"? Is this a CL-ism? Do we want it?</p> <p>Answer: cl-format doesn't print nil as "Nil". The ₍) construction is a case control operator. In this case, it capitalizes the each word in the expression: <a href="http://www.lispworks.com/documentation/HyperSpec/Body/22_cha.htm">http://www.lispworks.com/documentation/HyperSpec/Body/22_cha.htm</a>.</p> <p>In general, I've suppressed the obvious "CL-only" stuff like upper case symbols and such and replaced them with the corresponding Clojure conventions.</p> Approval Ok Global Rank Patch Code and Test
