In project.clj, dependencies are as follow:

:dependencies [[org.clojure/clojure "1.2.0"]
[org.clojure/clojure-contrib "1.2.0"]
[compojure "0.5.2"]
[ring/ring-jetty-adapter "0.3.1"]
[hiccup "0.3.0"]
[incanter "1.2.3-SNAPSHOT"]]


The function that generates the graphic should return the whole header:

{:status 200
:headers {"Content-Type" "image/png"}
:body in-stream}))


Finally, main is changed to:

(defn -main [& args]
(run-jetty example {:port 8080}))


The HTML generation has changed a bit (now it is dome by hiccup). Here is a good example of the new library usage.

I know this post is almost one year old, but would someone help me to run this? I downloaded Incanter and tried to build the corresponding example. “lein compile” fails like this:
“Compiling simple_web_app
Exception in thread “main” java.io.FileNotFoundException: Could not locate clojure/contrib/seq_utils__init.class or clojure/contrib/seq_utils.clj on classpath: (control.clj:9)”

Any ideas?

Thank you,

I’ll give it a whirl.

James.

To set up interactive development of this app if you’re using Leiningen and Swank, just run:
$ lein deps
$ lein compile
$ lein swank

(I actually had to change my Incanter dependency to [incanter "1.0-SNAPSHOT"], instead of [incanter "1.0-master-SNAPSHOT"] because lein couldn’t find the later version for some reason.)

Then from emacs, connect to the Swank server with ‘M-x slime-connect’, then evaluate the example file and start with server from the REPL with:
(simple-web-app/-main)

Make sure the app is working correctly by visiting: http://localhost:8080

Now you should be able to make changes to the running app.

Good luck,
David

yeah I’ve seen that video. It’s a good demo but it’s not going into the detail of how you would get slime to pick up the clojure version and all the other jars downloaded by lein.

For command line usage I’ve put together this variation of the common bash script, might be useful for others…

If I figure out how to do the same for emacs+slime I’ll post it here.

thanks,
