:bootclasspath causes java.lang.NullPointerException

Hello, I'm trying to compile my project with :bootclasspath set to true, so as to have the jar for a java agent added to my classpath, but in one of my projects it's generating java.lang.NullPointerException on this line: (def app (middleware/wrap-base #'app-base)) which is preceded by: (defr

Using a dynamic var for my database connection for implicit connections+transactions

Hello Clojurians, I found passing around the database connection to each function that uses it very error prone when you are using transactions as passing the wrong one could mean a query runs outside the transaction when in the source code it is inside the with-db-transaction function. So I en

I agree with you Mikera, it also maintains the homogeneity of always returning a sequence but some people disagreed with it, so an error might be better. -- J. Pablo Fernández http://pupeno.com On Jul 1, 2015 4:22 PM, "Mikera" wrote: > On Wednesday, 1 July 2015 12:55:28 UT

Hello Clojurists, Today I was surprised by the result of (flatten 1) which is '(). I was expecting '(1) or an error. Talking in some other people in #clojure @ clojurians.net, not everybody agrees that '(1) is a good result but that '() is somewhat surprising. Would it be better if it raised an

Re: Concerned about Clojure's license choice.

One thing that might be doable and acceptable is dual licensing. If Clojure is realsed as CPL *and* GPL, it can be combined with GPL programs and it is not in any way more free than the CPL (say, like if you add BSD in the bag). In that way you can keep GPLists happy and still use CPL. On Nov 1,
