Learn about the Elm programming language at elm-lang.org.

This is a fork of the Elm Compiler maintained by CurrySoftware GmbH. We merged a few bug fixes by the community and also expanded the reactor.

With Stack:

1. Install Stack (https://www.haskellstack.org)
2. Clone the repo
3. cd compiler
4. stack init
5. stack build

The built Elm executable will reside inside .stack-work/dist/<your-arch>/<cabal-version>/build/elm/elm. To install it link or copy it to the /usr/bin/ folder.

For example:

copy .stack-work/dist/x86_64-linux-tinfo6/Cabal-2.0.1.0/build/elm/elm /usr/bin/elm-dev

or ln -s .stack-work/dist/x86_64-linux-tinfo6/Cabal-2.0.1.0/build/elm/elm /usr/bin/elm-dev

This Elm-fork contains two new features in the Elm reactor:

1. The reactor can now emit compiled JavaScript instead of Html with the output=js parameter:

<script src="http://localhost:8000/src/Main.elm?output=js" charset="utf-8"></script>

1. The reactor can now emit code compiled in debug mode with the debug=true parameter:

http://localhost:8000/src/Main.elm?debug=true

or in combination with JavaScript output:

<script src="http://localhost:8000/src/Main.elm?output=js&debug=true" charset="utf-8"></script>

For a working example check out elm-reactor-example.

We are currently exploring the idea of building a private Elm package repository to facilitate usage of Elm in corporate environments.

Currently, it is not possible to use either local packages or another package repository than package.elm-lang.org.

We want to change that!

If you are a corporate Elm-user and want to support us or if you are interested in a closed beta please contact us through elm@curry-software.com.

Please contact elm@curry-software.com for support.

We also offer Elm Consulting Services for general help with Elm.
