# Bash environment setup file for the Drupal Scripts Library.
# See the README.txt file included with this distribution for more info on the project.
#
# Source this file to enable usful bash completion for the drupal script commands
# (Executing this file does not work -- must be sourced with '.' command.)
#
# This script must know how to find the Drupal Script Library when called.
# The library directory must be in the PATH or 
# the environment variable DRUPAL_SCRIPT_DIR must be set.
# If it the Drupal Script Library cannot be found, call is effectively a no-op.


### Envirnoment setup

# The name of a script we can be sure is in the library
EXAMPLE_SCRIPT="drupalLibrary.sh"

# Find the script home dir.
# If its already set, ensure it's pointing to a valid place.
if [[ -n "${DRUPAL_SCRIPT_DIR}" && -d "${DRUPAL_SCRIPT_DIR}" && ! -f "${DRUPAL_SCRIPT_DIR}/${EXAMPLE_SCRIPT}" ]]; then
	unset DRUPAL_SCRIPT_DIR

if [ -z "${DRUPAL_SCRIPT_DIR}" ]; then
	export DRUPAL_SCRIPT_DIR="`dirname "\`which ${EXAMPLE_SCRIPT} 2>/dev/null \`"`"
fi
# If not set here, give up.
if [ -z "${DRUPAL_SCRIPT_DIR}" ]; then
	# Can't really go very far from here.
	unset DRUPAL_SCRIPT_DIR

# Call the Drupal Scripts Library's 'bash_completion.sh' file
if [ -f "${DRUPAL_SCRIPT_DIR}/bash_completion.sh" ]; then

### Some utilities written as bash functions

# changes to a drupal install site dir
dcd() { cd "`drupalReport.sh sitedir "$1"`"; }

# pushd to a drupal install site dir
dpushd() { pushd "`drupalReport.sh sitedir "${1}"`"; }

# mysql into a drupal site db
dmysql() { mysql `drupalReport.sh dbconn "${1}"`; }

# Change to a specific module and theme

# make these autocomplete

### Drush setup 

export DRUSH_ROOT="${DRUPAL_SCRIPT_DIR}/drush"

	fi
fi

# If everything is kosher, provide drush functionality
if [ -n "${DRUSH_ROOT}" ]; then
	# Runs drush w/in context of Drupal Script Library
	# Uses PHP_HOME variable if available
	# $1 site name
	# $* remaining drush parameters
	ddrush() {
