Re: Adding jar to classpath in REPL

One alternative to this would be to start a Nailgun server. You can add to the classpath quite easily. That said, this looks pretty interesting. Ambrose On Thu, Mar 31, 2011 at 8:19 PM, Vitaly Peressada wrote: > Wanted to add jar to classpath without restarting REPL. Recalled java > reflection

Re: Midje 1.1 released (testing tool)

Great work Brian! One thing I was confused about in the 1.1-betas was the boolean return value of tests seemed random. ie. tests that pass don't always return true. Is this still the case? -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to t

Libraries and build management hell

Why does it have to be so complicated to use libraries? To use libraries, you need to learn how to operate half a dozen build tools and git because each library author distributes their library differently. If figuring out how to install an IDE with clojure wasn't bad enough, now you need to fi

Re: Libraries and build management hell

Leiningen definitely alleviates the hairiness of library management. But I wish people won't settle for a lein like solution for simple projects. As much as it helps, it is still an unnecessary burden and an obstacle to adoption, in my opinion and experience. -- You received this message becau

Re: Libraries and build management hell

This discussion is getting a lot of "What are you talking about? Leiningen is what you're looking for!" replies. I know. I'm a happy lein user, and use it and clojars frequently with some of my larger projects. I'm very grateful for the work Phil and the other contributors

Immutability rules when it comes to Ref type

Hi, I have a ref type that wraps a map, this map is going to embed many nested other maps. According to immutability rules, what happens when: A new nested map is updated (entry is removed or update) or even a new nested map is added to the master map that is wrapped by ref type? Thanks for help

Better ideas how to collect analytics data

Hi, I'm collecting analytics data. I used a master map that holds many other nested maps. Considering maps are immutable, many new maps are going to be allocated. (Yes, that is efficient in Clojure). Basic operation that I'm using is update-in , very convenient. Do you have a better idea how to c
