#
# PREREQUISITES
# -------------
#
# To use this script, your "master" SVN repository should have this layout:
#
#    root
#        DRUPAL-5
#            core
#                tags
#                trunk
#                    sites -> ../sites (symlink)
#                    profiles --> ../profiles (symlink)
#            profiles
#                tags
#                trunk
#                    someProfile
#                    anotherProfile
#
# When you branch or tag, you should update the svn:externals defitions to
# point to tags instead of trunks. You may want to try this script:
# http://svn.collab.net/repos/svn/trunk/contrib/client-side/svncopy/.
#
#
# WHAT DOES IT DO?
# ----------------
#
# This script should be applied on a checkout of a fresh (empty) repository
# that will be used for a Drupal project. It will checkout Drupal core and the
# desired install profile from your master SVN repository.
# Then it will create the necessary "sites" directory structure, including
# sites/foo.com, symlink sites/default to sites/foo.com and set the svn:ignore
# property on sites/foo.com/settings.php (to allow this site to work on any
# host). It will check out settings.php from cvs.drupal.org, but rename it to
# default.settings.php, and check that in into the repository. You'll have to
# copy this file and name it settings.php on each host you wish to install
# this site on.
# Finally, it updates the repository to get Drupal core and the install
# profile from the master SVN repository.

# Settings.

# URL of "master" SVN repository that contains Drupal core.
repository=svn://dev.wimleers.com/drupalbase

# Either DRUPAL4-7, DRUPAL-5 or DRUPAL-6.

# Do the magic.

# Step 0: svn update before doing anything, you have to be up-to-date before
# you can commit property changes.
svn up

# Step 1: import Drupal core through svn:externals.
echo "core $repository/$core_version/core/trunk" > prop.tmp
svn propset svn:externals . -F prop.tmp
svn ci -m "Imported the trunk of Drupal core version $core_version through svn:externals."

# Step 2: import the desired install profile through svn:externals.
svn mkdir profiles
echo "$profile_name $repository/$core_version/profiles/$profile_name/trunk" > prop.tmp
svn propset svn:externals profiles -F prop.tmp
svn ci -m "Imported the trunk of the $profile_name profile for $core_version through svn:externals."

# Step 3: create the necessary sites directory structure.
svn mkdir sites
svn mkdir sites/all
svn mkdir sites/all/modules
svn mkdir sites/$site
svn mkdir sites/$site/modules
svn mkdir sites/$site/themes
ln -s ../../files sites/$site/files # Symlink sites/$site/files to ../../files.
svn add sites/$site/files
ln -s $site sites/default # Symlink sites/default to $site.
svn add sites/default
svn ci -m "Created the sites directory structure."

# Step 4: ignore sites/$site/settings.php
echo "settings.php" > prop.tmp
svn propset svn:ignore sites/$site -F prop.tmp
svn ci -m "Configured SVN to ignore sites/$site/settings.php."

# Step 4: import the default settings.php from cvs.drupal.org and name it default.settings.php (like in Drupal 6).
cvs -z6 -d:pserver:anonymous:anonymous@cvs.drupal.org:/cvs/drupal export -r $core_version -d sites/$site drupal/sites/default
if [ ! `echo $core_version | grep -e "^DRUPAL-6$"` ]
then
	# Rename it to default.settings.php, this is fixed since Drupal 6.
	mv sites/$site/settings.php sites/$site/default.settings.php
fi
svn add sites/$site/default.settings.php
svn ci -m "Imported default settings.php for Drupal core version $core_version from cvs.drupal.org."

# Step 5: create a files directory and add the .htaccess for it.
svn mkdir files
chmod 777 files
# TODO get the .htaccess file!
svn add files/.htacces
svn ci -m "Created files directory and files/.htaccess."

# Step 6: now do an svn update to get the sources from the external repositories.
svn up

# Cleanup.
rm prop.tmp
