Expanding The Use Of Transducers To Atoms?

I've been reading about transducers with interest. The official docs at http://clojure.org/transducers say "*Because transducers are decoupled from input or output sources, they can be used in many different processes - collections, streams, channels, observables, etc.* " At this stage, the

Re: CCW bug [SEVERE]

Note that any of those operations you're talking about under the general heading of "I/O tasks" are very complex in a modern IDE, and there are a lot of seemingly unrelated code paths where a bug or some sort of unexpected condition might cause an infinite loop. And as a lot of people have noted, t

Have another +1 for clojure.test. It’s packaged with Clojure and while it’s not especially shiny I find that it gets the job done most of the time in addition to having the best tooling support. In my latest project, I’ve been enjoying using org.clojure/test.check

Hi folks Impressed that you've responded to my grumpy old man act so constructively - many thanks! Stu - I was aware that I could run the REPL without Leiningen - the Minimal Install section is pretty clear. But there didn't seem much point in having Clojure without any access to the build to

Transactions themselves are not queued (besides the obvious queueing of threads when you have more threads than cores). What gets adaptively queued is the historical values of refs involved in transactions. So if you have three concurrent transactions running, and three refs are involved in two of

Leiningen setup for modifying a library the project is depending on

I need to make some modifications to a library that my project is depending on.  Currently Leiningen downloads the lib from clojure and uses that lib.  Can I set things up so it uses the files I have cloned from github instead?  I have searched the docs but can't find any ideas how to do this.

a) you should rant about programmer(s). Exactly which one 'made a mistake' remains to be proven. b) Eclipse is a complex IDE, CCW runs on top of it as a plugin, it's at the mercy of the other pieces it depends on to run correctly. Stating who made the mistake requires some deep digg

Thank you! Clojure is a brilliant language, and this project was supposed to prove (mostly to myself) that it deserves the attention I'm devoting to it. I cannot even imagine doing something similar in any other language I know. I'm not saying it wouldn't be possible, but it certainly won't fit
