Overview

The z3c.jbot (or "Just a bunch of templates") package allows drop-in page template overrides.

It works by giving page templates a canonical filename which you can use to provide a replacement in your own package. Simply register a template overrides directory and give your new template the canonical filename.

Overrides may be registered for a specific layer or any layer.

Canonical filename

The canonical filename is defined as the path relative to the package within which the template is located with directory separators 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

Registering an overrides directory

A Zope component configuration directive is available to configure overrides.

<include package="z3c.jbot" file="meta.zcml" />

<browser:templateOverrides

directory="<directory>" layer="<layer>" />

Performance considerations

The use of jbot adds to the general page load time. On a site with many templates this may be as much as 20 ms per request (a 7% increase on my machine).
