Pythonic web.py

Making web.py request handling more pythonic.

import lessweb

def hello(ctx, name):
  if not name:
    name = 'World'
  return 'Hello, ' + name + '!'

urls = ('GET', '/(.*)', hello)

app = lessweb.application(urls, locals())

All those magical web.* are now available in context variable.

def hello(ctx):
  user_data = ctx.input(color=[])
  if 'color' not in ctx.cookies and not user_data.color:
    ctx.setcookies('color', 'blue')
  return 'Hello, from ' + ctx.env.get('REMOTE_HOST') or ctx.ip

urls = ('GET', '/', hello)
import lessweb
app = lessweb.application(urls, locals())

Only a part of web.py request handling has been masked with less.web. Rest of them are required to do what they did already.

import web
import lessweb

def redirect_to_referer(ctx):
	referer = ctx.env.get('HTTP_REFERER', 'http://webpy.org')
	raise web.seeother(referer)

urls = ('GET', '/', redirect_to_referer)
app = lessweb.application(urls, locals())

It's implemented as a tiny pythonic wrapper around web.py request handling.

The idea is to allow all request/response manipulation through ctx(context) of the handler function rather than module(web) level functions. ctx is basically web.ctx of web.py, which is already used to set and access request context. It also wraps other module level functionality of web.py such as header, input, cookies, sessions to yield a more pythonic interface.

To use sessions you have to configure session store in config as follows.

web.config.sessionstore = web.session.DiskStore('sessions') # for disk store, other stores can be used similarly.
