Added XML requests for plex, but will be replaced with a api request handling JSON objects instead. Also created cpuTemp for reading linux cpu temps, and added this to app API

"""Word completion for GNU readline.
|
||||
|
||||
The completer completes keywords, built-ins and globals in a selectable
|
||||
namespace (which defaults to __main__); when completing NAME.NAME..., it
|
||||
evaluates (!) the expression up to the last dot and completes its attributes.
|
||||
|
||||
It's very cool to do "import sys" type "sys.", hit the completion key (twice),
|
||||
and see the list of names defined by the sys module!
|
||||
|
||||
Tip: to use the tab key as the completion key, call
|
||||
|
||||
readline.parse_and_bind("tab: complete")
|
||||
|
||||
Notes:
|
||||
|
||||
- Exceptions raised by the completer function are *ignored* (and generally cause
|
||||
the completion to fail). This is a feature -- since readline sets the tty
|
||||
device in raw (or cbreak) mode, printing a traceback wouldn't work well
|
||||
without some complicated hoopla to save, reset and restore the tty state.
|
||||
|
||||
- The evaluation of the NAME.NAME... form may cause arbitrary application
|
||||
defined code to be executed if an object with a __getattr__ hook is found.
|
||||
Since it is the responsibility of the application (or the user) to enable this
|
||||
feature, I consider this an acceptable risk. More complicated expressions
|
||||
(e.g. function calls or indexing operations) are *not* evaluated.
|
||||
|
||||
- When the original stdin is not a tty device, GNU readline is never
|
||||
used, and this module (and the readline module) are silently inactive.
