Changes each adjustment method to take a preserve parameter when
setting the temperature instead of parsing the preserve option
from the command line/configuration file. This helps resolve the
issues around #513:
- This allows the preserve option to be implemented as a
command-line switch (-P). This switch _disables_ the preservation
of existing gamma ramps. Having a command-line switch makes it
easier to use directly with manual or one-shot mode.
- The preserve options is on by default, so continual mode as well
as other modes will default to applying the color adjustment
on top of the current gamma ramps.
- Preserve is always disabled in reset mode so resetting works
as expected again.
Create options.c which contains functions for initializing and
parsing options from the command line and the configuration file.
Program options that were previously local variables in main() are
moved to the options_t struct.
Rearrange checks and verbose output in main() to bring back checks
that were accidentally left out when time-based adjustments were
enabled. This includes the output indicating the daytime/night
temperatures and the check that the temperatures are valid.
Allow setting the time of the dawn and dusk transition periods
directly in the configuration file. If these are specified, the
location provider is not needed and is therefore not initialized.
Based on patch by Martin Nicolay <edelschimmel1@gmx.de>.
Simplify implementation of fades in continual mode. A fade is now
applied anytime the change in color temperature, brightness or
gamma is greater than a preset threshold. This means that a fade
is applied if the location provider suddenly updates to a new
location or if the currently time suddenly jumps e.g. after waking
up the computer from sleep. An easing function is applied to the
fade to make it more pleasant.
Use the term "fade" instead of "transition" for the short (~5s)
fade between color temperatures. The term "transition" is now only
used for the transition phase between daytime and night.
The setting "transition" in the configuration file is now deprecated
and "fade" should be used instead.
Change location provider implementations so it is possible for
location providers to dynamically update the location. This
commit adds the interfaces and infrastructure in redshift.c
but none of the location provides are changed to become dynamic.
Fixes#188
When I moved the macro definition below all of the includes, I got the
following compiler warning:
/usr/include/glib-2.0/glib/gmacros.h:246:0: note: this is the location
of the previous definition
#define CLAMP(x, low, high) (((x) > (high)) ? (high) : (((x) < (low))
? (low) : (x)))
So, that's the macro definition that was being used whenever "CLAMP" was
used. It's pretty obvious what went wrong.
This changes the transition_levels_t to transition_scheme_t and
adds two fields day, night of type color_setting_t. This
encapsulates all the information needed to calculate the current
color setting from an elevation.
Build failed on windows platform since pause() is not available. The
function is not needed on the windows platform so we just define a
noop pause() macro.
The gamma adjustments made with the Quartz (OSX) method are tied
to the process so when we exit, the gamma adjustments are reset.
Therefore we need to run a loop that breaks on CTRL-C, after the
gamma adjustments are made.
Hooks are executable scripts in ~/.config/redshift/hooks/ that
are run when a certain event happens. The first parameter to the
script indicates the event and further parameters may indicate
more details about the event.
The event "period-changed" is indicated when the period changes
("night", "daytime", "transition"). The second parameter is the old
period and the third is the new period. The event is signaled when
Redshift starts up with the old period set to "none".
The static string array period_names contains strings that are printed
but these were not marked for translation. This is fixed now by adding
the _N() macro and calling gettext() when the strings are used.
This keeps a copy of the previous color_setting_t in the loop so
that we can avoid printing the color temperature and brightness if
they did not change.
Changes all set_temperature function in gamma adjustment methods
to take a color_setting_t pointer with the color settings.
Colorramp functions are similarly changed to take a color settings
struct.
Move color settings (temperature, gamma and brightness) into a
struct for each period (day, night). Change the interpolation
function to interpolate all values between these structs.
