I did the upgrade. seemed okay. I a resumed doing the enlive tutorial,
and now when i :
user=> (load "tutorial/scrape1")
nil
nothing comes back.
type returns, nothing.
type (+ 1 1), and i get:
user=> 2
Odd.
From then on works as expected. Even when (load "scrape1")
------
tutorial : http://github.com/swannodette/enlive-tutorial/
source for scrape1:
(ns tutorial.scrape1
(:require [net.cgrand.enlive-html :as html]))
(def *base-url* "http://news.ycombinator.com/";)
(defn fetch-url [url]
(html/html-resource (java.net.URL. url)))
(defn hn-headlines []
(map html/text (html/select (fetch-url *base-url*) [:td.title :a])))
(defn hn-points []
(map html/text (html/select (fetch-url *base-url*) [:td.subtext
html/first-child])))
(defn print-headlines-and-points []
(doseq [line (map #(str %1 " (" %2 ")") (hn-headlines) (hn-points))]
(println line)))
