This package provides an extension to the BFG framework for integrating code with templates and resources – what’s known as the application skin.
You can use the package in a variety of ways. It’s designed to be immediately useful for most applications and flexible enough to scale to complex use-cases.
Some examples:
Integration is available for templates, routes and views. Discovery at run-time is supported [1].
Skin objects live in a global namespace. You can organize the space using directory nesting. The following example illustrates the mapping from the file system to the skin object space (where ./ corresponds to some package path):
./skins/index.pt => "index"
./skins/images/logo.png => "images/logo.png"
↳ mount point
The mount point constitutes a skin directory. You can register as many skin directories as you need. The files found under each directory will be entered into the global skin object space. In this way, new registrations can override previous ones.
Note in the example that index.pt appears on the skin side without its file extension. This is a behavior of the skin factory for template files (with the .pt extension).
We come back to this in much more detail, but here’s how you would register the ./skins directory using ZCML (we use the relative path here, assuming the ZCML configuration file is in the same directory):
<configure xmlns="http://namespaces.repoze.org/bfg">
<include package="repoze.bfg.skins" />
<skins path="skins" />
</configure>
That’s it! This is all you need to start using skin objects in Python code. The index name now maps to the ./skins/images.pt file on disk:
from repoze.bfg.skins import SkinObject
index = SkinObject("index")
This is a callable; it renders the template and returns an HTTP response object. If you provide keyword arguments, they will be passed into the template. Note that for skin templates (like "index"), the optional first two positional arguments are mapped to context and request.
The package is written and maintained by Malthe Borch and Stefan Eletzhofer. Available as-is under the BSD license. To contribute or get support for this package, please visit the #repoze channel on Freenode IRC or write to the repoze-dev mailinglist.
The package has 100% test coverage. This documentation itself is tested using the manuel library which works with the standard testrunner. You can run all tests from the command-line using:
$ python setup.py test
This allows you to make sure the package is compatible with your platform.
