MOTIVATION
==========
sunny is been written because I am too used to "night colors" on various
operating systems. The "default" 6500K temperature is "too much" for me.
During the day, I use a temperature of 5600K. When the sun sets, I shift
around 2300K, depending on my humor.
LIMITATIONS
===========
First of all, IMHO, gamma should be monitor property and screens that
use that monitor should inherit that. Instead on mos, gamma is applied
on each screen. That means sunny can only changes gamma on each screen.
Second, screen must be created with the attribute SA_GammaControl set to TRUE.
Workbench is not created with that attribute, so a patch to OpenScreenTagList
is needed to intercept the opening of "Workbench" and add SA_GammaControl, TRUE
to its init attributes. The patch must be applied before LoadWB is called.
Luckly, LoadWB is called in MOSSYS:S/startup-sequence after S:user-startup .
So, all you have to do is add the following two lines:
run <>NIL: C:sunny
C:WaitForPort SUNNY
at the beginnig of your S:user-startup. If you run sunny after, without having
booted with the patch active, sunny will be not able to change the screen
temperature.
Third, if Workbench is opened with SA_GammaControl set to TRUE, gamma in
Settings/screen Resolution/Edit/Gamma are not applied to the monitor.
They are saved, but you can't see what you are doing.
Forth, are the above values considered? They aren't at the moment.
intuition.library has a bug that prevents reading them. You must
wait for intuition "version>60" or "version=60 revision>40" (aka mos>3.18).
So, the initial gamma ramp is a linear "default" one. Probably it is what you
use every day, anyway.
Finally, mouse pointers: the more the color is in the "red-zone", the more
mounse pointers (any mouse pointer) will look like an alien entity. There
is nothing you can do: mouse pointers are rendered in a lower level than
screen gamma on our graphics cards. Look online to find many infos about.
Only modern graphic card could fix that.
BUGS
====
Oh dear, this is still a beta version. It works fine, but it has many things
not yet implemented. But it is "usable".
HOW TO
======
Copy sunny to C: Add the two lines as above to your S:user-startup and reboot.
Via Exchange or in a shell, open sunny interface and set your latitude and
longitude. These are in decimal form; the latitude is positive for the north
emisphere and negative for the south emisfere; the longitude is positive at east
of Greenwich and negative at west of Greenwich. These values are probably alrady
derived from the system. If you live in a small nation, you can leave them as
they are (f.e you don't live in USA, Russia, Cina, Indonesia, Brasil and so on).
Adjust the temperatures for the night time and the day time and save.
Tell me what is wrong and what to change. Of course I will not implement
stuff like geolocation.
USAGE
=====
sunny must be started early in S:user-startup
If run twice, it opens its window.
When its window is closed, all MUI resources are freed.
It's command line arguments are;
CX_PRIORITY/K/N,CX_POPKEY/K,CX_POPUP/S,SCREEN/M:
Don't use CX_POPUP in s:user-startup !!!
It's ICON tooltypes are
CX_PRIORITY=PRIO/N
CX_POPKEY=KEY
CX_POPUP
SCREENS=SCREENLIST
From version 0.5, sunny accepts a screens list at startup, f.e.
you can run sunny as
run DETACH sunny Workbench M@Muiscreen
or as a tooltype
SCRENS=Workbench:M@Muiscreen
to make sunny operates on Workbench ad Muiscreen; note that for
MUI screens, you must add M@ to the screen name.
P.S.
For translators: if you wish, you can add your name to
MSG_About_Text; to generate a sunny.ct file, just do:
make ctfile
