Ticket #16537: gvim

#!/bin/sh
#
# This shell script passes all its arguments to the binary inside the Vim.app
# application bundle.  If you make links to this script as view, gvim, etc.,
# then it will peek at the name used to call it and set options appropriately.
#
# Based on a script by Wout Mertens and suggestions from Laurent Bihanic.
# This version is the fault of Benji Fisher, 16 May 2005.

# First, check "All the Usual Suspects" for the location of the Vim.app bundle.
# You can short-circuit this by setting the VIM_APP_DIR environment variable
# or by un-commenting and editing the following line:
# VIM_APP_DIR=/Applications

binary="/Applications/MacPorts/Vim.app/Contents/MacOS/Vim"

# Next, peek at the name used to invoke this script, and set options
# accordingly.

# GUI mode will always create a new Vim instance, because Vim can't have
# more than one graphic window yet.
# The program should fork by default when started in GUI mode, but it does
# not; we work around this when this script is invoked as "gvim" or "rgview"
# etc., but not when it is invoked as "vim -g".

        # path names for any filenames you specify, which is hard.
