Add actions to volume/power/proximitySensor from lockscreen, camera, and other apps.

N9 Button Monitor | mt-toggle for n9bm

Highlights:
  • Toggle flashlight/torch from lockscreen
  • Take pictures from lockscreen {quickSnap}
  • Focuses/snaps pix in camera, using VOL+ instead of touch-button
  • Music suite lockscreen controls
  • Take a screenshot {goes into MyDocs}

Features:
  • Run arbitrary commands or certain builtin actions
  • Per-screen actions {do different things in lockscreen, camera, FBReader, mplayer, etc.}
  • Buttons: proximitySensor, volumeUp, volumeDown, cameraBtn {n950}, powerBtn, bluetoothHeadsetButtons
  • Click patterns: single-click, double-click, treble-click, long-click-start, long-click-stop
  • Simple config file, plus an ugly gui for editing it if you really want.
  • Changes are automatically picked up without restart when you edit or use the gui.
  • Optional mt-toggle for turning on/off


Installation:
dpkg --force-depends -i n9-button-monitor_*.deb
#force-depends installs dependencies, like apt-get -f install


https://github.com/teleshoes/n9-button-monitor

config file is located at /home/user/.config/n9-button-monitor.conf
Default Config {this gets created if there is no file}

feel generous?

you need to define your own getActions() function.

heres an example that does the camerra hack {vol+ to take pictures in camera app} and play/pauses music using mplayer
Code:
def getActions():
  return [
    Action(volup, cond=appOnTop("camera-ui"),
      action=cmd("xresponse -d 820x240,820x240 -w 1")),

    Action(volup, cond=screenLocked,
      action=cmd(
         "killall mplayer || " +
         "find ~/MyDocs/Music -iname *.mp3 -print0 | " +
         "xargs -0 mplayer"))
  ])

i put the above script in /usr/bin/n9-button-monitor, chmod +x.

i run it on startup with upstart.

/etc/init/n9-button-monitor.conf
Code:
# Description of the script, mandatory
description "Startup script for n9-button-monitor"

# Author e-mail address, mandatory
author "elliot.wolk@gmail.com"

start on filesystem or runlevel [2345]
stop on runlevel [!2345]

#none: stdout to /dev/null
#output: direct stdout to console
console output

#if application exits, restart max 3 times within 300 secs
respawn
#respawn limit 3 300

exec /usr/bin/aegis-exec -s -u user bash -c 'DISPLAY=:0 n9-button-monitor'

the next things i plan on doing are
1) investigating consuming button presses, overriding the default button actions like zooming/volume when an action is defined in the script. {or maybe just overriding it period in all cases, and simulating all the actually useful ones with actions in the script}

2) making the volume keep the phone's ringer volume and speaker volume in lockstep. so many times ive turned down the vol only to have loud music blast out of it. what id do is make it so that every time you press a volume button, ill get the ringer volume and set the phone volume to some variation on that.

3) separating out the action configuration from the script, so you dont need to be a python developer to use it. i imagine a simple rc file a la
~/.n9-button-monitor
[volume-up-press]
screen_lock = start_music
camera_on_top = snap_picture

[volume-up-release]
always = sync_volume

i would need to find out what people would even want to use this for, and add all of them to the rc-file grammar.

4) implement state for macro-ish controls
e.g.: make it so pressing and holding volume up, and then pressing volume down, and then releasing volume down and then releasing volume up, turned on the flashlight for 20 seconds

"UP DOWN down up" => "flashlight on; sleep 20; flashlight off"

{i think im going to rename the vol+/vol- keys INC and DEC to avoid confusion with button-up and button-down for keypresses.}

please please share when you do. im dying for things for this to actually do. so far:

1) play/pause/skip/prev music players on the lock-screen
2) flashlight on/off on the lock-screen
3) camera take picture {and maybe focus first}
4) camera take delayed picture
5) answer calls, instead of swiping up

1, 3, and 4 are easy and done. the camera doesnt focus first though, so what id REALLY like to do is make it so volUp-PRESS focuses, and volUp-RELEASE snaps. i dont think i have enough control to do this, though.

if anybody thinks of anything even remotely awesome, please post.
