Elm 0.18 and older are a little bit trickier to support than Elm 0.19 and later, because older Elm versions used multiple binaries (elm, elm-make, elm-package, elm-reactor, elm-repl) instead of just one.

But I have an idea how it could be done!

1. Extract everything from tar archives.
2. mv elm elm-real
3. Create an elm shell script that delegates to the other binaries and falls back to elm-real

I have not had a need for this myself yet, so I haven’t implemented this.

Let me know if you need Elm 0.18 support!

Windows should be supported!

I haven’t developed on Windows for almost ten years, so I have no idea what’s it like anymore.

Currently, elm-version is a shell script that tries to be as portable as possible – it even works on Alpine Linux! Is it possible to run sh scripts on Windows these days? I’m thinking about Windows Subsystem for Linux and the new https://github.com/microsoft/terminal. If so, that would be awesome!

Other ideas:

• Make a PowerShell version in addition to the shell script.
• Make a cross-platform Node.js version in addition to the shell script. The shell script is probably going to be more performant.
• Make a cross-platform version in Haskell, Rust, Go or whatever in addition to the shell script. Maybe the shell script is good for CI and Docker, and the other version could be optimized for humans.

I think that we need to make an installer, just like Elm, that automatically adds the binaries to PATH. Because manually adding stuff to PATH in the Windows settings is tedious.
