Drop-in template overrides.
Project description
Overview
The z3c.jbot (or “Just a bunch of templates”) package allows drop-in page template overrides. It works on Zope 2 and Zope 3. The Chameleon rendering engine is supported [1].
Any template that is defined as a class-attribute can be overriden using jbot, e.g. those used in views, viewlets and portlets. The template overrides may be registered for any request layer or only a specific layer.
To override a particular template, first determine its canonical filename. It’s defined as the path relative to the package within which the template is located; directory separators are replaced with dots.
Example:
Suppose you want to override: /plone/app/layout/viewlets/logo.pt
You would use the filename: plone.app.layout.viewlets.logo.pt
Simply drop the file in a directory and register that directory for use with jbot using a ZCML-directive:
<include package="z3c.jbot" file="meta.zcml" />
<browser:templateOverrides
directory="<path>"
layer="<layer>" />
Use of this package adds a small (2-3 ms per request on Plone) to the total application response time.
