dv.xdvserver 1.0b8

A server for the Deliverance/XSLT compiler

Introduction

dv.xdvserver is a simple piece of WSGI middleware that can execute the two step compile-and-run XSLT transforms of xdv.

It takes two required parameters:

• rules: a path to a file containing Deliverance rules
• theme: a URI or path to a theme HTML file

In addition, it can take several optional parameters:

• absolute_prefix: if given, relative urls in the theme file will be made

  into absolute links with this prefix.

• notheme: a set of regular expression patterns (or just simple names) that

  will be matched against the incoming path to allow the theme to be switched off for some paths. Multiple patterns should be separated by newlines.

• live: set to True to recompile the theme on each request, rather than on

  startup only.

• compiler: a path to the XSLT file that can turn theme+rules into a compiled

  theme. The default, bundled version will probably suffice in most cases.

• boilerplate: a path to the XSLT file that contains boilerplate XSLT

  instructions. The default, bundled version will probably suffice in most cases.

Configuration

You can use this middleware in a Paste Deploy pipeline. Here is an example configuration file of an application that themes a Plone site running on http://localhost:8080/demo. Static resources are served from /static:

[server:main]
use = egg:Paste#http
host = 127.0.0.1
port = 5000

[composite:main]
use = egg:Paste#urlmap
/static = static
/ = default

[app:static]
use = egg:Paste#static
document_root = %(here)s/static

[pipeline:default]
pipeline = egg:Paste#cgitb
           egg:Paste#httpexceptions
           theme.default
           zope.proxy

[filter:theme.default]
use = egg:dv.xdvserver#xdv
theme = %(here)s/static/index.html
rules = %(here)s/static/rules/default.xml
notheme =
    /emptypage

[app:zope.proxy]
use = egg:Paste#proxy
address = http://localhost:8080/VirtualHostBase/http/localhost:5000/demo/VirtualHostRoot/
