TODO v2.0

ToDo list for Fenrir Version 2.0 
Things with not so deep knowledge needed are marekd wiht "(Easy for contribution)". so just start with that :).

General:  
- implement onScreenUpdate commands
  read highlighted text mode
- be more event based (vcsa sets POLLPRI)
  http://scotdoyle.com/python-epoll-howto.html
- try to make it more asynchronus with multpible threads
- leave review on typing (Easy for contribution)

- implement commands
  attributes_curr_char (Easy for contribution)
  https://github.com/jwilk/vcsapeek/blob/master/linuxvt.py
- generic list (convert clipboard management) (Easy for contribution)
    next item
    pref item
    curr item
    first item
    last item
  
Braille Support:
  brailleFocusMode:
    - manual = no automatic toggle command used
    - last = follow last used cursor
  print cursor in review
  print cursor in textmode
  command toggle used cursor (in manual brailleFocusMode)  
  capture input from braile
  make routing keys assignable by keyboard
  make brailleTable configurable
  pkg-config --variable=tablesdir liblouis

Driver:
- implement PTY Screen driver (to use gnome-terminal and other terminal emulators)
  https://docs.python.org/3.2/library/pty.html
- implement PTY Input driver  
- ATK input driver (don't grab on graphical interface)
- try to autodetect encoding (Easy for contribution)
  https://stackoverflow.com/questions/6396659/how-do-you-get-the-encoding-of-the-terminal-from-within-a-python-script

Settings:
- configuration should be overwritable with parameter and alternative paths (Easy for contribution)
- write settings (Easy for contribution)
- menue for settings configuration (Easy for contribution)

Application Profiles
- reimplement process detection without subprocessing // this is started by chrys
- fenrir is not able to detect the current application inside of screen.
    ps -e  -H -o pid,pgrp,ppid,tty,cmd
    http://stackoverflow.com/questions/24861351/how-to-detect-if-python-script-is-being-run-as-a-background-process/24862213
    fd = os.open("/dev/tty5", os.O_RDONLY )
    os.tcgetpgrp(fd)
- add perApplicationTrigger trigger
    per application commands
    per application onScreenChange
    per application onInput
- per application shortcuts

-----------DONE----------------
- Add nice dummy drivers as template or for debugging
- reimplement detection code for X11
- initial translate structure (manuelcortez Thanks!)

- add a configurable place where you can place own commands or overwrite existing commands without need to change default code
- implement autodetection of plugged and unplugged input devices (python-pyudev) for evdev driver
