Eta - Modern Haskell on the JVM

The Eta programming language is a dialect of Haskell which runs on the JVM and has the following goals:

• accessibility for beginners from imperative languages, especially Java
• compatibility with GHC 7.10.3's Haskell.

Visit eta-lang.org for instructions on getting started.

Current Status

• Sibi for helping out with porting packages and setting up TravisCI.
• Anton Gushcha for giving detailed bug reports on the Java FFI.
• Balaji Rao for contributing to the design & implementation for some parts of the FFI.
• Javier Neira for making Eta work on Windows and testing extensively across multiple Windows versions.
• Paavo Parkkin for improving error checking in the compiler to prevent runtime bugs.
• Ashley Towns for implementing low-level primitives in the standard library.
