How to integrate F# and Notepad++

People a faced with challenges trying to install F# interactive plugin for Notepad++ (example). I am not an exception, going through all of this I want to share my experience.

  1. First of all download latest version of the Notepad++ and install it (default installation settings). For today it is Notepad++ 6.1.5 (Jul 16 2012)
  2. Download NPPFSIPlugin Version 0.1.1.
  3. Extract dll from achieve and copy it to Notepad++\plugins\ folder. On the my Win7 64bit machine it is c:\Program Files (x86)\Notepad++\plugins\.
  4. Open or re-open you Notepad++ application.
  5. Go to Plugins\F# Interactive\Options menu item.
  6. Specify Binary Path to fsi.exe file.
    For example:
    F# 2.0C:\Program Files (x86)\Microsoft F#\v4.0\fsi.exe
    F# 3.0 – C:\Program Files (x86)\Microsoft SDKs\F#\3.0\Framework\v4.0\fsi.exe
    Before use this paths check that you you have installed appropriate version of F# in that 
  7. Save you changes. Now it should work.
    Alt+T to open F# interactive
    Alt+Enter to to send selected text to F# Interactive

It is also very nice to have a F# syntax highlighting.
