Re: First foray into clojure - questions for new project

It was helpful for me to start from the ground up: Got familiar with ring, then compojure, hiccup, noir, etc. Getting familiar a library at a time prepared me better for managing the more comprehensive frameworks when it came time to customization. FWIW. On Wednesday, November 14, 2012 12:20:23

cemerick made a screencast of how to get started with Clojure, which takes you through getting started with the tools, and making a web app. It is probably a great place to start: http://cemerick.com/2012/05/02/starting-clojure/ For details on the Clojure web stack, I really like this guide:

Re: First foray into clojure - questions for new project

Only catch is that the free level of Heroku isn't very useful with Clojure. The app keeps going to sleep, and the first person to hit your app will have a noticeably lengthy wait because Clojure takes a long time to start up. -- You received this message because you are subscribed to the Google

Hi all, I've heard many good things about clojure, and I'm finally taking the plunge. I've been using Hunchentoot on SBCL for several years, and I've finally decided it's time to move to a current lisp with a proven platform and (from what I have heard) a great community. I have a project cur

Re: Lots of newbie clojure questions

Incidental mutability is the key. Functional programming doesn't eliminate mutability, it manages it: only the parts of the system that truly need to change state do so. Everything else is pure and easy to write and test. Contrast that with imperative programming where it's hard to tell which s

Re: Lots of newbie clojure questions

1. What is the justification for using a map as a function? I find this to be very confusing. In math, a function is a mapping from one set to another, so from that perspective it makes good sense for a clojure-map to be a function from its set of keys to its set of values. The justification here

Lots of newbie clojure questions

Hello, I'm a long-time Java programmer who's tired of mutability getting in my way. I've been largely enjoying the pervasive use of closures in JavaScript, and though I'd check out Clojure. So far so good. It installed easily and the REPL is easy to use. I've watched the screencasts and have writt

Hi everyone, I'm working on cleaning up the wikibook some, and I've got a few questions. If anyone could answer, that would be a great help. What is the minimum required JVM version for clojure? What versions of Java have been tested? What versions of Java are supported? Thanks! --~--~---
