Add a "reset" option

[LapTop006]

Please add a command line option to remove the shift and then exit.

For some reason the version in debian has a broken tray icon, and without a reset option it's hard to figure out how to reset the display without restarting X.

Run "xgamma -gamma 1.0" ?

[Jon Lund Steffensen (jonls)]

I'm not sure I understand why you'd have to reset. Doesn't redshift restore the color when you kill it?

[Dan Helfman (witten-torsion)]

Not if you use the -o option.. Or presumably if redshift somehow crashes.

[Dan Helfman (witten-torsion)]

To be more specific: If you run redshift with the -o option, it'll set the color to something reddish and then exit. At this point, there's no way to reset the color back to its original levels without running xgamma.

[Jon Lund Steffensen (jonls)]

Thanks for explaining this, Dan. I see what you mean. Redshift can restore the colors without using xgamma (in an undocumented way), by setting the temperature to 6500K with -o. There should probably be a command line option to reset the color directly.

[Dan Helfman (witten-torsion)]

Attached is a patch against 1.3 that adds a new -x reset option (-r was already taken). The patch essentially does what you suggest: Simulate -o -t 6500:6500. The new option doesn't require a latitude or a longitude. Let me know if you'd like to see any changes to the patch.

[Dan Helfman (witten-torsion)]

And here's a one-line patch to the README to document the new option.

[Jon Lund Steffensen (jonls)]

Thanks. I'll include it in the next release.
