Hello folks. You may have heard some rumours and/or tweetage about Cake and Leiningen. During the Conj I met with Justin Balthrop and some of the other Cake developers. They were interested in joining forces to develop a single unified build tool for Clojure. We talked it through and I think Leiningen could definitely benefit on the one hand from having a few of Cake's features ported over and on the other hand from gaining a bunch of new developers. This will mean Cake may see another few releases but will have its development efforts directed to Leiningen.[1]
In particular I'm thinking of two or three things that make sense to take from Cake for Leiningen 2.0. Firstly there's the use of in-process classloaders for project execution. I've wanted this for a while, and they've got a nice well-tested implementation they're offering to have ported right over. This should speed things up and offer fairly significant memory savings. The other definite win would be taking the SCP implementation for Clojars uploads. There is a lein-clojars plugin, but it has some issues with keys that have prevented it from being considered for inclusion. Another thing we may take is the notion of "profiles" or environments in which tasks execute. Right now Leiningen has a notion of dev time vs production, which is just a single bit that determines whether dev-dependencies, tests, and test resources are on the classpath. Cake (and Maven IIUC) expand on this and allow various config options to be grouped and activated on a per-profile basis. I'll start a separate thread discussing this since there's still a fair bit more I'd like to understand about how people are using this in Cake and how simply it could be implemented. We're still thinking through whether it makes sense for Leiningen to offer persistent/daemonized JVMs to reduce execution time; it may be simpler to delegate this to Jark[2] instead since it could be considered fairly orthogonal. If you use Cake and Leiningen and have some other features you would miss, please mention them. So I'm excited to welcome them to the team. Happy Hacking. -Phil [1] - https://groups.google.com/group/clojure-cake/browse_thread/thread/186ec36c2426996e [2] - http://icylisper.in/jark -- You received this message because you are subscribed to the Google Groups "Clojure" group.
