irxevent - infrared X-event sender
irxevent [option]... [config file]
Irxevent is a program to send button clicks and key presses to X applications triggered by a LIRC driven remote control. You can control your favorite CD/MP3 player, your TV tuner program or any other X application that responds to keyboard or mouse input. If you like to you can send emacs ^X^S from your armchair.
Irxevent is a complement to irpty(1).
Irxevent works with the same config file as irexec and irpty (~/.config/lircrc). For a complete sample lircrc look at examples/lircrc.
Part of your .lircrc could look like this:
begin prog = irxevent button = VIDEO_UP config = Key SHIFT-KP_Add CurrentWindow end begin prog = irxevent button = VIDEO_DOWN config = Key SHIFT-KP_Subtract CurrentWindow end begin prog = irxevent button = STOP config = Key ctrl-c CurrentWindow end begin prog = irxevent button = 0 config = Key f xawtv config = Key f xawtv end begin prog = irxevent button = POWER config = Key q xawtv end begin prog = irxevent button = CH_DOWN config = Button 1 329 92 kscd end begin prog = irxevent button = UP config = Button 1 110 80 GQmpeg end begin prog = irxevent button = DOWN config = Button 1 130 80 GQmpeg end
Simply said config = lines may look like this:
config = Key [shift-][ctrl-][alt-]<key> [Focus] <windowname> | WindowID <id> | CurrentWindow | RootWindow config = Button <button> <x> <y> [Focus] <windowname> | WindowID <id> | CurrentWindow | RootWindow config = xy_Key <x> <y> [shift-][ctrl-][alt-]<key> [Focus] <windowname> | WindowID id | CurrentWindow | RootWindow
Some more examples:
config = Key Up xawtv config = Key Down xawtv config = Button 1 50 110 xclickme config = Key q xawtv config = Key ctrl-c mpg123 config = Key shift-Page_Up rxvt
In BNF this looks like:
LINE = "config =" <KEY|BUTTON|XYKEY> <TARGET> | "config =" <KEY|BUTTON|XYKEY> "Focus" <TARGET> XYKEY = "xy_Key" <x_position> <y_position> <MOD><KEYSPEC> KEY = "Key" <MOD><KEYSPEC> MOD = ["shift-"]["numlock-"]["ctrl-"]["alt-"]["meta-"] ["numlock-"]["mod3-"]["mod4-"]["mod5-"]["altgr-"]["scrlock-"] KEYSPEC = Keyname | "KeySym:"KeySym | "KeyCode:"KeyCode BUTTON = "Button" <1..5> <x_position> <y_position> TARGET = Windowname | "WindowID" id | "CurrentWindow" | "RootWindow"
If you have problems finding the coordinates for a button click you can try xev -id <window_id>. The window_id can be found using xwininfo.
There are programs that do not accept any synthetic X-events by default because they can cause security problems. Currently xterm and xemacs are known to ignore events simulated by irxevent.
You can however make xterm accept external events by enabling "Allow SendEvents" in the "Main Options" (hold down the Ctrl button and press the left mouse button inside the xterm window). You can as well place this line into your .Xresources file to change this permanently:
Yet another possibility is to start xterm like this:
xemacs will accept events if you set a built-in variable. The following was taken from the online help:
*Non-nil means to allow synthetic events. Nil means they are ignored.
Beware: allowing emacs to process SendEvents opens a big security hole.
In order to allow events you have to evaluate this lisp code (press Meta-x and enter the following expression):
(setq x-allow-sendevents t)
Placing this line into your .xemacs-options file should have the same result.
If you have problems sending events please drop me an email.
