Create Languages Fast
Create your project, import the dependency and define your language. Still too slow? The sample starter project allows you to get a running start.
Building Blocks
LARF uses an object orientated approach to language development. All literal, operation or statement logic is contained within single classes.
Flexible Framework
It is completely customisable with the ability to override any property and component. Don't like the default parser? Write your own!
