Seajure Meetup Notes
Intro
These are notes from our meetups. If we talk about a good tool or library, I’ll try and add a link here. Feel free to add your own notes.
February 2015
We tried to create a simple web application that echo’s messages (dare I say, a “twitter clone”?…well, not even close, actually.)
Code is at https://github.com/Seajure/echo.
Below is a snippet I saved from an earlier attempt:
(defonce hollas (atom []))
(defn layout [title & body]
(html5
[:head
[:meta {:charset "UTF-8"}]
[:title title]]
[:body
[:div.container {}
body]]))
(defn holla-form []
(form/form-to [:post "/"]
(form/label "holla" "What do you want to holler?")
(form/text-area "holla")
(form/submit-button "Holla!")))
(defn display-hollas [hollas]
[:ul
(for [holla hollas]
[:li {} holla])])
(defn index []
(layout "Holla"
(holla-form)
[:div {:class "clear"}]
(display-hollas @hollas)))
(defn add-holla [holla]
(swap! hollas conj holla)
(index))
(defroutes routes
(GET "/" [] (index))
(POST "/" [holla] (add-holla holla)))
(def app (handler/site routes))
(defn start [port]
(ring/run-jetty app {:port port :join? false}))
(defn -main []
(let [port (Integer. (or (System/getenv "PORT") "8080"))]
(start port)))
March 2015
We’re planning on going over Marcus M’s Star Trek port.
- Reddit discussion
- https://github.com/marcusm/startrek-clojure
- I’ve forked it into the org, in case we make any changes we want to keep.
- UPDATE: I committed the changes we made, if anyone wants to see them.
