How to handle difficult old-style add-ons.
Sometimes an “old-style” add-on is distributed as foo.tar.gz and extracts to foo/, but the package is called bar. This can be a problem when using the plone.recipe.productdistros recipe because when bar is extracted to parts/productdistros/foo it will not work.
Fortunately there is hexagonit.recipe.download, which allows you to specify the destination. For example, ZNagios (an add-on that integrates Zope with Nagios) is available as a tarball here:
If we use productdistros, we end up with ZNagios installed in parts/productdistros/trunk. But if we use hexagonit.recipe.download we can control the destination.
[buildout]
parts = znagios
[znagios]
recipe = hexagonit.recipe.download
url = http://svn.gocept.com/viewcvs/ZNagios/trunk.tar.gz?view=tar
destination = products/ZNagios
strip-top-level-dir = True
After running Buildout you should have the following in your products/ directory:
/products/ZNagios
/products/ZNagios/COPYRIGHT.txt
/products/ZNagios/LICENSE.txt
/products/ZNagios/README.txt
/products/ZNagios/__init__.py
/products/ZNagios/check_zope.py
/products/ZNagios/munin_client.py
/products/ZNagios/version.txt
/products/ZNagios/zeo_munin.py
/products/ZNagios/zope.cfg
