About
What is this site?
Las3rfl lets you create, edit, save, fork and run code in your browser. It's a shameless knockoff of Wonderfl with two main differences:
- Las3rfl uses the Las3r programming language instead of Actionscript 3.
- Wonderfl has much nicer documentation. Go to http://wonderfl.net/about/ to get the general idea.
What's this Las3r thing anyway?
Las3r is a lisp compiler for the AVM2 (aka the flash player). In my opinion it's best described as a port of Clojure circa 2008 minus the math stack and concurrency features.
Getting started
No need to register, just click the write new code link, or find some code you'd like to change and click fork.
Important note
To see better error messages and uncaught exceptions you need a debugger version of the Flash plugin. If you don't have one installed (click to check) you can get it from Adobe's download page.
If you have any questions or comments, please feel free to post them in the forum, or try the #las3r IRC channel on freenode.
