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

Works like a charm. Being on a mac with all sorts of weird characters in filenames you might want to change
"set filename to POSIX path of input"
to
"set filename to quoted form of POSIX path of input"

I took the idea further, now you can edit any text snippet (e.g. in Mail, Safari etc.) in MacOS with VIM:

I ran into a problem with filenames containing spaces, and found the following helped:

set filename to quoted form of POSIX path of input

This option does not bring the terminal to the foreground if the stager is on ((

These are great and work on macOS 13. Signal boosting!

Updated version with bringing terminal (iTerm2 + nvim) to the foreground:

on run {input, parameters}
	set filename to quoted form of POSIX path of input
	set cmd to "clear;cd `dirname " & filename & "`;nvim " & 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
	
	tell application "System Events"
		tell process "iTerm2"
			set frontmost to true
		end tell
	end tell
end run
