Clojure helpers
Table of Contents
These are helpful functions I include in all my Clojure(Script) projects.
Note not all of them are my own original idea.
1 Clojure
1.1 logging
Just call log with any number of strings as arguments.
(defn log "concatenate and save to file" [& strings] (spit "/tmp/cljdebug.txt" (str (reduce str strings) " ")))
1.2 map-of
For when you need to put some variables into map format:
(defmacro map-of [& xs] `(hash-map ~@(mapcat (juxt keyword identity) xs)))
1.3 url encoding
Shortcut for URL encoding/decoding
(defn urlencode [foo] (java.net.URLEncoder/encode foo "UTF-8")) (defn urldecode [foo] (java.net.URLDecoder/decode foo "UTF-8"))
2 ClojureScript
2.1 logging
Just call log with any number of strings as arguments.
(defn log "concatenate and print to console" [& strings] ((.-log js/console) (reduce str strings)))
2.2 get by id/class
Simple shortcuts
(defn byid "shortcut for getting element by id" [id] (.getElementById js/document id)) (defn byclass "shortcut for getting element by class" [name] (.getElementsByClassName js/document name))
