Practical unit-of-measure calculator DSL for Clojure / ClojureScript
Frinj is a practical unit-of-measure calculator DSL for Clojure / ClojureScript.
Key features;
Add the following line into your Leiningen :dependencies [frinj "0.2.5"]
.
user=> (use 'frinj.repl)
user=> (frinj-init!)
user=> (override-operators!)
user=> (fj 2000 :Calories :per :day :to :watts)
;; "1163/12 (approx. 96.91666666666667) [dimensionless]"
There are a few differences when running Frinj on Node / in a browser. See this wiki page for details.
To generate the browser demo, run lein cljsbuild once
. Then start a web server in the browser-example directory, and visit it. You should see the examples page.
For example;
$ cd browser-demo
$ python -m SimpleHTTPServer
then visit http://localhost:8000
in a browser and click on the demo.html
file.
See example calculations for ideas...

Live units for currencies, precious metals etc, some examples
