Is there a way to add a listener to watch brightness changing?

I'm on linux and my code as below ::

brightness.set(0.5).then(() => {
console.log('Changed brightness to o.5');
}).catch(err => {
console.log(err);
})

getting Error: No backlight device found.
Thanks in advance.

It's pains me deeply to open this issue...

It seems like http://www.nirsoft.net/utils/nircmd2.html has ability to set brightness. Not get though, but I guess set is good enough for now. Make sure to use the nircmdc binary. You need to run it in a real Windows install, not VM.

I'm having the same problems with your library that also affects this one too. I can set the brightness, the script closes, and then 30 seconds later the OS resets the brightness back to the level it was before the script ran.

I have disabled the "Automatically adjust brightness" setting in the OSX control panel, and I don't know why else this would be occurring.

Hello. I get a crash on my system:

    $ brightness
    $ brightness 0.8

Setting the brightness with $ brightness <number> does indeed work.

Currently only setting the brightness is supported.

What operating systems and computers is currently supported? Can't get it to work on Windows 10 build 10166 on a Samsung utralbook.

Brightness is not changing in my Elementary OS.

would a PR with ios support be accepted to this library? I'm interested in doing that. Need it for work plus it's hacktoberfest.

Is there any way to prevent using sudo every time I run this thing? It can be very harmful.

Since updating to macOS 10.12.4, changing the screen brightness using the following pattern leads to different/unwanted/unintended behavior:

1. change brightness from command line using "brightness"
2. change brightness again using a function key (F1/F2)

Instead of the 2nd step changing the screen brightness starting from the level set in step 1, macOS 10.12.4 uses the brightness level from before step 1 as its starting point.

Error: Only Windows systems are supported

I think it should catch the errors anyway.

$ brightness s

        throw new TypeError('Expected a number');
              ^

Please add typescript support

declare module 'brightness' {
  export function set(brightness: number): Promise<void>
  export function get(): Promise<number>
}

Should implement a interactive CLI where the user can click uparrow/downarrow to adjust the brightness.

This is the error that occurs when executing on linux platform.
