This page is a stub for collating automated theme upgrade steps.

You'll want to run these sed commands over (the copy of) your old d6 themes and then do a diff to make sure nothing is broken.

Please edit this page to refine the steps you have taken.

If your theme is derived from a classic drupal theme, carried forward into drupal 7, then diff3 is a useful tool:

f=style.css
a6=~/antarqld.org.au/sites/all/themes/ANTaRQld2
g6=~/antarqld.org.au/themes/garland
g7=~/copyc.antarqld.org.au/themes/garland
a7=~/copyc.antarqld.org.au/sites/all/themes/a3

cd ~/tmp

cp $a6/$f a6.$f
cp $g7/$f g7.$f  
cp $g6/$f g6.$f  

# MYFILE OLDFILE YOURFILE

diff3 -m a6.$f g6.$f g7.$f > a7.$f

echo "Now you need to edit a7.$f and then:"
echo "   cp a7.$f $a7/$f 

The output will be the differences between the garland theme (from d6), the garland theme from d7 and the modification you made from that theme.

To do some automated search and replaces, sed is useful:

s|<body(.*)>|<body\1> <?php print $page_top; ?>|

#$search_box is now a block.
/$search_box/d

s|\$primary_links|$primary_menu|g
s|\$secondary_links|$secondary_menu|g
s|\$left|$sidebar_first|g
s|\$right|$sidebar_second|g
s|</body>|<?php print $page_bottom; ?></body>|
