[](https://travis-ci.org/Bogdanp/markii)

## Installation

```python
import webapp2

from functools import partial
from markii.frameworks.webapp2 import handle_error
from paste import httpserver


class Handler(webapp2.RequestHandler):
def get(self, n):
self.response.write(str(int(n)))


app = webapp2.WSGIApplication([
webapp2.Route(r"/<n:.*>", handler=Handler)
], debug=True)
app.error_handlers[400] = partial(handle_error, code=400)
app.error_handlers[404] = partial(handle_error, code=404)

httpserver.serve(app, host="127.0.0.1", port="8080")

## Warning

Make sure you only use MarkII in development mode.

## Gotchas

On AppEngine, you must call `markii.appengine.fix_appengine()` inside
your error handler.

## Text editor support

MarkII supports opening files in your editor when you double click a
frame by taking advantage of OSX's URL handler feature. See:

MarkII borrows its ideas (and most of its look) from [better_errors](https://github.com/charliesome/better_errors).
