Script for selecting and calling the correct Griffon version when you have more than one version installed

griffon.sh

#!/bin/sh
# Author: Deluan (http://techbeats.deluan.com)

# Check if GRIFFON_HOME is set
if [ -z "$GRIFFON_HOME" -o ! -d "$GRIFFON_HOME" ]; then
	echo "Error: GRIFFON_HOME not set"
	exit 2

# Try to get the version from the command line

# Or else get the version from the application.properties in the current directory
[ -z "$VERSION" -a -f "$APP_PROP" ] &&
    VERSION=`awk -F'=' '/app.griffon.version/ { print $2 }' $APP_PROP | tr -d '\r\n'`

# Or else use the default version
[ -z "$VERSION" ] &&

export GRIFFON_HOME=${BASE_GRIFFON_PATH}/griffon-${VERSION}
GRIFFON_CMD=${GRIFFON_HOME}/bin/griffon

exec $GRIFFON_CMD $*

Prerequisites

• All your Griffon versions must be installed under the same base directory. Ex:

  /opt/griffon-0.3.1
  /opt/griffon-0.9
  /opt/griffon-0.9.1a
  

• GRIFFON_HOME environment variable must be set and point to your "default" Griffon installation

• This script was tested on Mac OS X (Snow Leopard), Linux (Ubuntu) and Windows (with cygwin)

Installation

• Download the script: http://gist.github.com/656064
• Include the folder where it is installed in your PATH.
• Exclude $GRIFFON_HOME/bin from your PATH

Usage

Using the script is as transparent as possible:

• If you invoke it from a project folder, it will detect the version used by the project and call the correct griffon (if it is installed in your system)

• If you invoke it from any other folder that does not contain a Griffon project, it will call the "default" Griffon installation

• If you want to call a specific Griffon version (i.e. when doing an upgrade) you can specify the version you want in the first parameter. Ex:

  $ griffon 0.9.1a upgrade
