Otto is an HTTP publisher which uses a routes-like syntax to map URLs to code. It supports object traversal.

You can use the publisher to write web applications. It was designed with both small and large applications in mind. We have tried to incorporate elements of existing publishers to allow diverse and flexible application patterns while still being in concordance with the Zen Of Python.

Here's a variation of a familiar theme:

System Message: WARNING/2 (<string>, line 19)

Literal block expected; none found.

import otto import webob import wsgiref.simple_server

app = otto.Application()

@app.connect("/*path/:name") def hello_world(request, path=None, name=u'world'): return webob.Response(u"An %d-deep hello %s!" % (len(path), name))

System Message: WARNING/2 (<string>, line 25); backlink

Inline emphasis start-string without end-string.

wsgiref.simple_server.make_server('', 8080, app).serve_forever()

This release is compatible with Python 2.4+.

See the documentation for this release.
