I am proud to announce a new Scala project called “Frins”.
Frins is a practical unit-of-measure calculator DSL for Scala.
- Tracks units of measure through all calculations allowing you to mix units of measure transparently
- Comes with a huge database of units and conversion factors
- Inspired by the Frink project
Full source code available on github.
To wet your appetite head straight over to the example calculations.
How Frins came about
About a year ago I created Frinj. With Frinj I tried to marry some of the joys of one of my favorite programming languages (Frink) with the Clojure REPL. I was quite pleased with the results, and the response was encouraging.
Recently I started reading Odersky (again) and when I came to the chapter on implicit conversions I got the idea of trying to create a Frinj style DSL for the Scala interpreter. I could leverage some of the efforts made in Frinj (like parsing the Frink unit database) and the result is quite cool.
It’s indeed possible to create a very fluent and powerful DSL using some of Scala’s core language constructs!
