A bundle of all Elm tools: elm, elm-server, elm-repl, and elm-get.

If you have any trouble installing at all, open an issue on this repo and then continue to the Platform Agnostic instructions which work on any OS.

Mac — use the installer and continue the getting started walkthrough for Mac.

Windows — use the installer and continue the getting started walkthrough for Windows. If you run into issues compiling programs, you may need to manually set your ELM_HOME environment variable to C:/Program Files/Elm Platform/0.12.3/share as reported here.

Arch Linux — follow these directions and then jump to the My First Project section.

Platform Agnostic — download the Haskell Platform then run these commands:

cabal update
cabal install elm elm-server elm-repl elm-get

Again, all this should work on any platform, from Windows to Ubuntu.

Update to a newer version of Elm by just running the installer again. They link to the latest versions, and they will safely overwrite old executables and paths so your machine is in a consistent state.

This installs four command line tools: elm, elm-server, elm-repl, and elm-get. To be able to call them from the command line, you may need to add them to your PATH.

Now we will create a simple Elm project. The following commands will set-up a very basic project and start the Elm server.

mkdir helloElm
cd helloElm
printf "import Mouse\n\nmain = lift asText Mouse.position" > Main.elm
elm-server

The first two commands create a new directory and navigate into it. The printf commands place a simple program into Main.elm. Do this manually if you do not have printf. The final command starts the Elm server at localhost:8000, allowing you to navigate to Main.elm and see your first program in action.

If you are stuck, check to see if anyone has had a similar issue. If not, open a new issue or email the list or ask a question in the #Elm IRC channel.
