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/CLJ-879 Clojure <p>There's been discussion previously about the complexity of the ns<br/> macro. In particular the fact that :use causes all vars to be referred<br/> by default is widely seen as unfortunate, and the distinction between<br/> use and require is a source of conceptual overhead for people new to<br/> the language.</p> <p>We can't change the fact that :use refers everything by default<br/> without breaking lots of existing code. But it would be possible to<br/> enhance :require to support referring specified vars, leaving us free<br/> to deprecate or otherwise discourage the use of :use.</p> <p>Clojure-dev thread discussing this: <a href="http://groups.google.com/group/clojure-dev/browse_thread/thread/91b708ddb909affd">http://groups.google.com/group/clojure-dev/browse_thread/thread/91b708ddb909affd</a></p> CLJ-879

Allow :require to support a :refer clause

Enhancement Minor Closed Completed Phil Hagelberg Phil Hagelberg patch, test Thu, 17 Nov 2011 16:08:40 -0600 Fri, 17 Feb 2012 14:18:28 -0600 Fri, 17 Feb 2012 14:18:28 -0600 9 7 <p>Patch containing implementation, test, and documentation.</p> <p>Any chance we could get some discussion going on this?</p> <p>I'd love to see this discussed.</p> <p>So... how about it? Thoughts?</p> <p>patch still applies cleanly to master, tests pass</p> <p>there is a warning when you run the tests though:</p> <p> <span class="error">&#91;java&#93;</span> Testing clojure.test-clojure.keywords<br/> <span class="error">&#91;java&#93;</span> <br/> <span class="error">&#91;java&#93;</span> Testing clojure.test-clojure.load<br/> <span class="error">&#91;java&#93;</span> WARNING: with-bindings already refers to: #'clojure.core/with-bindings in namespace: clojure.test-clojure.require-scratch, being replaced by: #'clojure.main/with-bindings<br/> <span class="error">&#91;java&#93;</span> <br/> <span class="error">&#91;java&#93;</span> Testing clojure.test-clojure.logic<br/> <span class="error">&#91;java&#93;</span> <br/> <span class="error">&#91;java&#93;</span> Testing clojure.test-clojure.macros</p> <p>Vetted. Patch is good, although it needs docstring updates in 'require'</p> <p>Not Vetted. I can't remember what the names mean. Ready for Rich. That's "Test" right?</p> <p>My mistake. The docstring is included in 'require', but not in 'refer', which also changed. But the <b>public API</b> of 'refer' did not change. So this patch is good.</p> <p>Not "Test." Screened. The patch is Screened. I hate this.</p> <p>Patch applied.</p> Approval Ok Global Rank Patch Code and Test
