Picasso

Picasso is a simple web framework built on Pump.

Examples

Here's a simple example demonstrating the use of routes, forms, sessions and redirects.

from picasso import *

def home(req):
  if not req["session"].get("user"):
    return redirect("/login")
  return "<h1>Welcome back, %s!</h1>" % req["session"]["user"]

def login(req):
  return "<form method='post'><input type='submit' value='login' /></form>"

def login_post(req):
  req["session"]["user"] = "James"
  return redirect("/")

routes = setup_routes(
  GET("/", home),
  GET("/login", login),
  POST("/login", login_post),
  routing.not_found("<h1>Not Found</h1>"))

app = setup_app(routes)
pump.adapters.serve_with_paste(app)

Here's an example blog written with Picasso.
