Open With Emacs

I have finally found a decent solution to use Emacs when interacting with the "Open with" context menu option on Windows.

Basic idea:

• Run Emacs in server-mode
• Use AutoHotkey to create a binary that either starts Emacs or connects to it using emacsclient

Steps:

• Create a new .ahk script based on the content below
• Adapt the bin directory variable to your needs
• Use Ahk2Exe to turn the script into a binary
  • Note: Make sure you select the correct base file (to support AutoHotkey v2 instead of v1)
• Copy the binary to a directory that is on PATH (or add a new entry)
• You can now choose your new binary as an "Open with" option when opening files

path := A_Args[1]
bin := "C:\ProgramData\Emacs\bin"
command := Format("{1}\emacsclientw.exe --no-wait --alternate-editor={1}\runemacs.exe {2}", bin, path)
Run command
