First hundred days of Clojure | byte bohemian In politics you have a one hundred days period of grace. In December I started to work with Clojure, so I guess it’s time to have a clojure look. In the last couple of years I encountered a couple of different languages. At scoyo it was ActionScript and Flex from Adobe. When we started to work on our new product I said to my boss and my colleagues: In Java I know how a state of the art application has to look like, but I have no clue how to build a Clojure application. Leiningen (aka lein) – The build and dependency managmement tool for Clojure.Noir – A nice library to build websites/-services in Clojure.CongoMongo and mongoDB – The database driver and the database we use. My first days with Clojure When you are coming from a language like Java you are used to some things like:Structure everything – Static typing is your friend, so smack every data you have into a class.

You'll notice the paths are different (I changed it during my first post) but obviously they aren't relevant. But with 1.0 out now I haven't had as many issues. Rob - show quoted text -
Incanter: Statistical Computing and Graphics Environment for Clojure Basic Web Development | Clojure Documentation | Clojure Docs This guide covers building a simple web-application using common Clojure libraries. When you're done working through it, you'll have a little webapp that displays some (x, y) locations from a database, letting you add more locations as well. It's assumed that you're already somewhat familiar with Clojure. If not, see the Getting Started and Introduction guides.

This guide uses Clojure 1.5, as well as current versions of the component libraries noted below. Conceptual Overview of Components We'll use four major components (briefly described below) for our little webapp: RingCompojureHiccupH2 Ring Ring (at clojars) is a foundational Clojure web application library. For this tutorial, we won't actually need to deal with these maps by-hand, as you'll soon see. For more info, see: Compojure Hiccup [:p "Hello, " [:i "doctor"] " Jones."] becomes See Also
