http://dev.clojure.org/jira This file is an XML representation of an issue en-us 4.4 649 25-07-2011 http://dev.clojure.org/jira/browse/TNS-1 tools.namespace <p>The clojure 1.2 reader will allow invalid forms like {:key} to be read in, and only throw an exception on printing. Currently clojure.tools.namespace calls (read rdr) within a try form; the bug means that this particular type of error is never caught. This patch forces the reader to try and resolve with str, allowing clojure.tools.namespace to catch and bury the error.</p> <p>I was running into this with moustache templates from lein-newnew on the classpath; these contain namespace headers that look like (ns <tt>name</tt>.core). This would cause (clojure.tools.namespace/find-namespaces-on-classpath) to fail when printing its results but not when actually running.</p> Mac OS X, Clojure 1.2.1, Leiningen 1.6.2 TNS-1

Workaround to Clojure 1.2 reader bug

Defect Major Resolved Completed Stuart Sierra Sam Ritchie Wed, 14 Dec 2011 16:52:05 -0600 Tue, 24 Apr 2012 14:07:05 -0500 Tue, 24 Apr 2012 14:04:28 -0500 2 2 <p>Funny, jira picked up the moustache markup. a bad namespace looks like (ns { { name } } . core).</p> <p>Ping &#8211; Stuart, any thoughts on this?</p> <p>Why should tools.ns do this? If the syntax is wrong, it's wrong.</p> <p>Because without this patch, it's impossible to catch and bury errors from invalid reader syntax. I believe this comes from a bug in the reader that was fixed with 1.2.</p> <p>Declined. It is not the responsibility of this library to catch errors in old versions of Clojure.</p> <p>Reopening because this is still a visible issue for some libraries. I still don't like it, but I'm going to include it.</p> <p>Patch applied.</p> <p>Great, thanks!</p> Global Rank Patch Fixed
