Languages, and about languages, on the BEAM

Overview

This document is intended to list (a) languages implemented to run on the BEAM, the Erlang virtual machine, and (b) documents (articles & presentations) about the hows and whys of writing languages to run on the BEAM.

For the moment, and for want of a better name, I call such languages “BEAM languages” (although I have heard that there are other Erlang VMs, …).

I would like the document to be comprehensive, or at least “representative”. If I have missed a BEAM language, some noteworthy discussion about a BEAM language, or documentation about implementing languages targetting the BEAM, please let me know through the usual channels (issues, forks, PRs, tweets, emails, etc.).

Thank you.

Languages

The original repo (on Google Code) no longer exists, but there are several forks, e.g.:

A couple of blog posts from 2008 (the second is by the original developer of erlyjs):

idris-erlang (2014-15)

This is an Idris package (therefore requiring Haskell and Idris) which compiles Idris source code into erlang source code.
