Open files in same window under Mac OS X

This tip shows you how to open files from the command line in the same window (Vim instance), using applescript. The applescript is specific to Vim.app.
Create a file called gvim.scpt (for example) with the following applescript code:
on run argv tell application "Vim" repeat with n from 1 to (count of argv) set theUnixPath to item n of argv set theMacPath to (POSIX file theUnixPath) as string open file theMacPath end repeat activate end tell end run
This applescript tells a running Vim.app to open each argument in a new buffer. The script can be invoked with the 'osascript' command ('man osascript' for details): a good way to do this is to create a shell script somewhere in your path:
#!/bin/sh osascript /path/to/gvim.scpt $*
What this doesn't do yet: Create the files automatically if they do not exist. In fact the script will fail and complain if you pass the name of a file that doesn't exist, and any following files also won't be opened.
