open file with vim in iTerm2 by double click

VimLauncher.scpt

on run {input, parameters}
	set the_path to POSIX path of input
	set cmd to "vim '" & the_path & "'"
	set isRunning to (application "iTerm" is running)
	tell application "iTerm"
		activate
		if isRunning then
			if (count of windows) > 0 then
				set sess to (current session of (create tab with default profile of current window))
			else
				set sess to (current session of (create window with default profile))
			end if
		else
			set sess to (current session of current window)
		end if
		tell sess
			write text cmd
		end tell
	end tell
end run

Thank's for a very helpful script!

I would add a delay until a current window exists in cases when iTerm is not running so that it has time to open a new window:

repeat until (exists current window)
    delay 0.1
end repeat

Result:

on run {input, parameters}
	set the_path to POSIX path of input
	set cmd to "vim '" & the_path & "'"
	set isRunning to (application "iTerm" is running)
	tell application "iTerm"
		activate
		if isRunning then
			if (count of windows) > 0 then
				set sess to (current session of (create tab with default profile of current window))
			else
				set sess to (current session of (create window with default profile))
			end if
		else
			repeat until (exists current window)
                            delay 0.1
                        end repeat
			set sess to (current session of current window)
		end if
		tell sess
			write text cmd
		end tell
	end tell
end run
