activity-based rules?

[wchristian]

Any chance of adding rules based on time since last user interaction? I'd like to be able to set rules like "switch to low power mode if i haven't touched the keyboard/mouse in half an hour" and "switch to balanced mode when i touch the mouse/keyboard".

I really like the idea.
I don't know how to reliably check for mouse keyboard activity. But I will look into it. WinAPI is gonna be my friend here, I assume.

I want to add some things anyways. I'm just a little short on time lately. Hopefully I can get something done on the weekend.

Note for myself: GetLastInputInfo
If only life was always this easy!

using System;
using System.Runtime.InteropServices;

class IdleTimeHelper
{
    [StructLayout(LayoutKind.Sequential)]
    struct LASTINPUTINFO
    {
        public uint cbSize;
        public uint dwTime;
    }

    [DllImport("user32.dll")]
    static extern bool GetLastInputInfo(ref LASTINPUTINFO plii);

    public static TimeSpan GetIdleTime()
    {
        LASTINPUTINFO lastInputInfo = new LASTINPUTINFO();
        lastInputInfo.cbSize = (uint)Marshal.SizeOf(lastInputInfo);

        if (!GetLastInputInfo(ref lastInputInfo))
            throw new System.ComponentModel.Win32Exception();

        uint idleTicks = (uint)Environment.TickCount - lastInputInfo.dwTime;
        return TimeSpan.FromMilliseconds(idleTicks);
    }
}

Hell yeah, glad i inspired you. Just as a note tho, it's also important to balance the added cpu use from polling that vs the responsiveness. :)

[SebastianBecker2]

I highly agree!
The good thing is, it shouldn't be noticeable, even with a 5 second interval.
I assume, the time since last user interaction isn't gonna be less than a minute.
Maybe I make it configurable. Both, the interval and the time since last user interaction that activates the rule.

Good news, bad news:
Bad news first: I will have to do some major rework. Otherwise I will make it soooo much more complicated to make any changes in the future. I hope I can get it done until the end of the year. At least to a beta version. It will need some thorough testing.

Good news: This was the only bad news. That is a good thing!
