Exporting API reference from Tornado app - Mistakes to avoid

April 30, 2014TechPython, tornadoticapix

I've developed a small RESTful service with Tornado and I wanted to generated doc for the exposed API. Lucky me, someone already thought about it and created the sphinxcontrib.autohttp.tornado addon for Sphinx.

The next few tips will help getting the work done:

If you're using python-3, you need to use this file tornado.py. The latest release 1.2.1 (as of 30/04/2014) doesn't work with python-3, because

methods = inspect.getmembers(handler, predicate=inspect.ismethod) # returns an empty array with python-3

1

methods = inspect.getmembers(handler, predicate=inspect.ismethod) # returns an empty array with python-3

The predicate needs to be changed to include ismethod or isfunction
In the subclass of the RequestHandler, be sure that the SUPPORTED_METHODS is defined as a tuple

SUPPORTED_METHODS=('GET') # WRONG SUPPORTED_METHODS=('GET',) # CORRECT

1
2

SUPPORTED_METHODS=('GET') # WRONG
SUPPORTED_METHODS=('GET',) # CORRECT
If you add a decorator to your handler methodes, be sure to use functools.wraps or functools.update_wrapper to copy the docstring of the original method to the function returned by the decorator.

LCD repair

March 6, 2014TechDIY, Electronicsticapix

In 2009, I bought a Iolair MB24W, one of those with a MVA display. Except the time when I had to reset the screen to restore the EDID (Press M, +, - until the blue led blinks 3 times), the screen works fine ... until recently.

The screen switches on but stays white. No picture at all, not even the OSD menu.

There is funny little usb gadget called the Blync identified by VID: 0x1130, PID: 0x0001.

It's a glowing RGB cube, but it has two defects for me:

the driver is only available for Windows
only 7 colors are available

Let's fix it.
