Build Status Erlant/OTP Release

Erlang VM byte code assembler for implementing compile-to-beam languages. The goal is to a provide delightful API for generating BEAM instructions from pure Haskell.

Usage

This example writes a simple module to a file:

import qualified Data.ByteString.Lazy as LBS

import Codec.Beam.Instructions (func_info, label, move, return')
import qualified Codec.Beam as Beam

main : IO ()
main =
  LBS.writeFile "test_module.beam" $
    Beam.encode "test_module"
      [ Beam.export "tuple_of_one" 0
      ]
      [ label 1
      , func_info "tuple_of_one" 0
      , label 2
      , move (Beam.Tuple [Beam.Integer 1]) (Beam.X 0)
      , return'
      ]

After you run that program, you can load the resulting module from the Erlang shell!

$ erl
1> test_module:tuple_of_one().
{1}

You can find an example project on GitHub.

Build

Use Stack:

stack build --test
