Fjord is an implementation of the F# programming language for the JVM.

The implementation is at very early stages, so if you are looking to use F# on the JVM, Fjord is probably not for you. However, if you are interested in hacking on F# implementation for the JVM, welcome on board!

Fjord is built and packaged with Apache Maven and requires Java 1.8 or higher to build and run.

To build F#, run:

export MAVEN_OPTS="-Xmx1g"
mvn package

To launch the F# interactive shell run:

./bin/fji

and you are greeted with:

Fjord

For help type #help
> _

You can then evaluate F# expressions:

> let x = 1 + 2
val x = 3

• Aims at F# 3.0 language compatibility

Want to help? Grab the F# specification, fork the GitHub repository, and send a pull request!
