Little ML'er in F# - a workshop. The reason for its name might become more clear if you do some of the exercises and/or read the book.

The exercises are based on this book, you should buy it if you are interested in knowing more about this and getting the proper explanations. http://www.amazon.com/The-Little-MLer-Matthias-Felleisen/dp/026256114X

Setup

The workshop will be given i Visual Studio Code using the Ionide plugin.

Manual Setup

You need to get F#, Visual Studio Code and the Ionide plugin. Follow the F# Software Foundation's installation guide for linux, mac or windows.

Getting weird F#-output in VSCode?

Ionide has a known bug, that can cause weird output in the F# terminal on some installations. If you experience this, include the following in your VS Code settings file:

{
    "terminal.integrated.flowControl": false
}

You can open the settings-file by pressing Ctrl + Shift + P and writing Open User Settings.

Love those custom keybindings?

If you want to move the cursor to the fsi-repl in VSCode without using a pointer device, you'll need a custom keybinding. Press Ctrl + K, Ctrl + S to open the user keybindings and enter the following to bind Ctrl + 4 to go to fsi-repl.

[
    {
        "key": "ctrl+4",
        "command": "workbench.action.terminal.focus",
        "when": "editorTextFocus"
    }
]

Property based assignments

These can be run either in

FSI

This requires mono to run, which can be setup on linux and mac.

They require paket to install FSCheck. https://github.com/ionide/ionide-vscode-paket Run > Paket:install (CTRL+SHIFT+P Paket install) to install required depedencies.

Using Expecto

Use (CTRL+SHIFT+P) and Expecto: Run to build and run the property based tests in dotnet core. This requires only dotnetcore to run, and should be multiplatform.

Assignments

The scripts in the assignments folder is meant to be evaluated and played with in FSI. Send a line to FSI using alt + enter in VSCode. There is no feedback on right and wrong, ask an instructor or ask @jonaswinje or @_teodoran or someone else on Twitter if you are not sure, or create a GitHub issue or something. The assignments are a bit open on purpose. We want you to play with the concepts.
