Re: [ANN] tools.analyzer[.jvm] 0.6.0 release, pass scheduler

Hi Nicola, why do you pass a set of vars to schedule rather than a set of functions? I'm just interested. It's unusual to see #' Dave On Friday, 19 September 2014 05:07:08 UTC+10, Nicola Mometto wrote: > > > Today I released version 0.6.0 of the tools.analyzer[1] and

Re: ANN: Potemkin 0.3.0

to answer my own question. It does not play well. I created a couple of simple macros that mimics the import-vars behaviour for fns and vars in clojurescript. On Sunday, 14 September 2014 17:53:47 UTC+10, Dave Sann wrote: > > Does Potemkin work well with clojurescript? > > I ha

Re: leiningen resources folder

clojure.java.io/resource isn't specific to the resources folder. It just scans the classpath. Your classpath probably looks like "test:src:resources" or something so "test" wins. If there was a test/readme.txt file you'd also get that rather than resources/readme.txt.
