After being asked to use Visual Studio 2015 for F#{.tweet-hashtag} Development, I decided it’s way more lightweight to to develop it on my Mac using Sublime Text 3.

Software you need installed:

• Install Mono on your Mac
• Of course Sublime Text 3
• And the best package manager for Sublime, Package Control.

Install (using package control) these packages with package control in Sublime Text:

• F# – Gives you syntax Highlighting
• F-Sharp – Autocomplete, tooltips, definitions, etc.
• SublimeREPL – A multi language REPL including F#

If you are used to Visual Studio for any F#{.tweet-hashtag} development; you can create some Sublime text keyboard shortcuts using your key bindings settings:

• Open REPL : CTRL+ALT+F
• Send selected code to REPL : CTRL+SHIFT+ENTER

The bindings I use are shown below:

You’ll want to configure Sublime 3 indentation settings to include these options to replace Tabs with spaces; as Sharp hates your tabs.

This setup also works on Sublime for Windows, but you need fsi.exe in your path and working with all dependencies (Windows SKD, .NET Framework etc.).
