If you're looking for help on how to use the program, just press
|
|
? while its running. This mess will not help you.
|
|
|
|
Urwid aint my speed. Hell, making complex, UI-oriented programs
|
|
aint my speed. So some of this code is pretty messy. I stand by
|
|
it though, and it seems to be working rather well.
|
|
|
|
Most of the functionality is crammed in the App() class. Key
|
|
handling is found in the other subclasses for urwid widgets.
|
|
An instantiation of App() is casted as `app` globally and
|
|
the keypress methods will call into this global `app` object.
|
|
|
|
There are few additional functions that are defined outside
|
|
of the App class. They are delegated to the very bottom of
|
|
this file.
|
|
|
|
Please mail me (~desvox) for feedback and for any of your
|
|
"OH MY GOD WHY WOULD YOU DO THIS"'s or "PEP8 IS A THING"'s.
