C:\Users\username>elm Hi, thank you for trying out Elm 0.19.1. I hope you like it! ------------------------------------------------------------------------------- I highly recommend working through <https://guide.elm-lang.org> to get started. It teaches many important concepts, including how to use `elm` in the terminal. ------------------------------------------------------------------------------- The most common commands are: elm repl Open up an interactive programming session. Type in Elm expressions like (2 + 2) or (String.length "test") and see if they equal four! elm init Start an Elm project. It creates a starter elm.json file and provides a link explaining what to do from there. elm reactor Compile code with a click. It opens a file viewer in your browser, and when you click on an Elm file, it compiles and you see the result. There are a bunch of other commands as well though. Here is a full list: elm repl --help elm init --help elm reactor --help elm make --help elm install --help elm bump --help elm diff --help elm publish --help Adding the --help flag gives a bunch of additional details about each one. Be sure to ask on the Elm slack if you run into trouble! Folks are friendly and happy to help out. They hang out there because it is fun, so be kind to get the best results!
