Getting Started with Eclipse and Counterclockwise
Install Eclipse (If you do nothave Eclipse installed, or you wantto make isolated tests of the Clojure plugin for Eclipse) Grab a recent version of eclipse, e.g. the “Eclipse IDE for java developers” from the download page Unzip it somewhere. The executable is eclipse (linux) or eclipse.exe (windows) located in the eclipse/ directory created by the unzip operation The first time Eclipse is run, it will ask you for a location on your disk where eclipse will put its metadata and will create new projects by default. Install Counterclockwise (the Clojure plugin for Eclipse) You install it via the “software update center”, that is: Menu Help > Install new software… Paste the following Counterclockwise url in the “Work with:” textbox: http://updatesite.counterclockwise.googlecode.com/hg/ Hit Enter Select counterclockwise, verify the “Contact all update sites during …” chekbox is checked, click next, accept licence, etc., restart Eclipse Go to menu Window > Reset Perspective ... this will reset the way the views are layout, and also and and place correctly the views contributed by counterclockwise (for now - July 2010 -, the Namespace Browser viewer, placed "behind" the code outline view) Create and run a simple Clojure project (Hello World) Open the Java perspective: Window > Open Perspective > Java (a perspective is a predefined layout of views, suitable for a particular type of development) Create a Clojure project: File > New > Project... > Clojure Project, name it firstClojureProject Create a Clojure source code file in the src/ directory: File > New > File, twist down firstClojureProject in the file creation wizard and select "src" as the the parent folder, and name the file helloworld.clj Type code in it to define a function: (defn hello [who] (str "Hello " who " !")) (leave the (ns helloword) call at the beginning of the file), save the file Run it: Select the firstClojureProject>src>helloworld.clj file, then menu Run > Run as > Clojure REPL. this evaluates the code and starts a REPL Call your function: > 1:1 helloworld=> (hello "Betty") > "Hello Betty !" Installing and running the labrepl environment for learning Clojure Install EGit, Git support in Eclipse (optional if you already use another git client) You install it via the “software update center”, that is: Menu Help > Install new software… Paste the following EGit url in the “Work with:” textbox: http://download.eclipse.org/egit/updates Hit Enter Select “Eclipse EGit feature”, verify the “Contact all update sites during …” chekbox is checked, click next, accept licence, etc., restart Eclipse Install m2e, Maven support in Eclipse You install it via the “software update center”, that is: Menu Help > Install new software… Paste the following maven2eclipse (m2e) url in the “Work with:” textbox: http://m2eclipse.sonatype.org/sites/m2e Hit Enter Select Maven Integration for Eclipse, verify the “Contact all update sites during …” chekbox is checked, click next, accept licence, etc., restart Eclipse Grab labrepl from git via EGit Menu File > Import … > Git > Git Repository ; Hit Next URI: git://github.com/relevance/labrepl.git ; Hit Next ; Hit Next ; Uncheck "Import Existing Projects"; Hit Finish Import the maven project into Eclipse Menu File > Import ... > Maven > Existing Maven Projects ; Hit Next Choose root directory (wherever you dropped the labrepl in the previous step); Hit Finish Wait while Maven does a bunch of stuff in the background Enable Clojure Support Right-click the "labrepl" project in Package Explorer and choose "Enable/disable Clojure language support" Run the labrepl Right click on project “labrepl” in the Package Explorer Run as > Clojure REPL In the REPL Console: (require 'labrepl) (labrepl/-main) Browse to localhost:8080 Enjoy the labs!
