[SOLVED] Ion3, statusbar monitor

Nikelandjelo · 10-11-2009, 01:43 PM

I wrote monitor for displaying pcm volume. It works after restarting/booting ion3, but it stops in 4-20 minutes, and I can't find the reason. Does anybody have ideas?

This is monitor's code:

Code:

local function update_pcm()
        local all_info = io.popen("amixer sget PCM"):read("*a");
	local value = string.match(all_info, "%d+%%");
	if (value == nil) then
		state = "Error";
	end;
	statusd.inform("pcm", value);
	pcm_timer:set(1000, update_pcm);
end;

pcm_timer = statusd.create_timer();

update_pcm();

I've solved this problem by myself. May be it's good to remove this thread.
But if smb wants to know, the problem was in:

Code:

local all_info = io.popen("amixer sget PCM"):read("*a");
local value = string.match(all_info, "%d+%%");

io.popen(...) returns nil sometimes, so error occurs in "string.match(all_info, "%d+%%");"
