Open file in Terminal Vim on OSX

readme.md

1. Open Automator
2. Choose "New Document"
3. Locate "Run AppleScript" and double-click it
4. Paste the Applescript code into the box
5. Save as /Applications/TerminalVim.app
6. In Finder, select some file you want to open in Vim, e.g. a .rb file.
7. Hit ⌘I to open the “Get Info” window.
8. Under “Open with:”, choose TerminalVim.app. You may need to select “Other…” and then browse.
9. Hit the “Change All…” button and confirm.

Now all .rb files in Finder will open in Vim.

TerminalVim.applescript

on run {input, parameters}
	
	set filename to quoted form of POSIX path of input
	
	set cmd to "clear;cd `dirname " & filename & "`;vim " & filename
	
	tell application "iTerm"
		
		tell the current window
			
			create tab with default profile
			
			tell the current session
				
				write text cmd
				
			end tell
			
		end tell
		
	end tell
	
end run

Tried the last version. Often there is an error:

You'll need to create a new window if one isn't there.
