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
|
|
- try to make it more asynchronus with multpible threads
|
|
- be more event based (vcsa sets POLLPRI)
|
|
http://scotdoyle.com/python-epoll-howto.html
|
|
Needed events:
|
|
screen update (vcsa sets POLLPRI)
|
|
plug input device (udev event)
|
|
screen changed (logind event, collides with screen update)
|
|
keyboard input (select, wait forever)
|
|
braille input (brlapi_readKey)
|
|
braille flush (timer, sleep)
|
|
Each event is watched in an own thread. This improves performance and reduce the load.
|
|
The event loop is to be done as "queue" since those are thread safe.
|
|
The threads are reading incomming data and add the events and data to the queue
|
|
the mainloop just reads the queue in an blocking way and executes the needed codepath with the data.
|
|
clean up the code for the events so that just the correct codepath is used:
|
|
- screen
|
|
- input
|
|
- new device
|
|
- implement commands
|
|
Tutorial Mode: navigate through a list of bound commands. speak binding and description.
|
|
attributes_curr_char (Easy for contribution)

|
- generic list (convert clipboard management) (Easy for contribution)

Braille Support:
|
|
brailleFocusMode:
|
|
- manual = no automatic toggle command used
|
|
- last = follow last used cursor
|
|
print cursor in review
|
|
print cursor in textmode
|
|
word wrapping (if word does not fit print it at next page)
|
|
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
|
|
returns on Arch:/usr/share/liblouis/tables

Driver:
|
|
- implement PTY Screen driver (to use gnome-terminal and other terminal emulators)
|
|

|
|
https://blog.konpat.me/pythons-pseudo-terminal-pty-examples/
|
|
- implement PTY Input driver
|
|
- ATK input driver (don't grab on graphical interface)

Settings:
|
|
- 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

|
|
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----------------
|
|
- initial working setup.py
|
|
- leave review on typing
|
|
- add dependency check (check-dependencys.py)
|
|
- 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
