Redshift hooks

Hooks to enhance redshift's abilities.

• brightness.sh - Set screen backlight brightness according to time of day.
• colorscheme.sh - Live-reload terminal colorscheme according to time of day

Installation

For each script, copy from hooks/script_name to .config/redshift/hooks/script_name. Each script may have its own installation instructions.

brightness.sh

Set screen backlight brightness according to time of day.

The default brightnesses for day, transition and night are 90, 60, 35, and the default fade time is one hour. If you wish to alter them, you can find them at the top of the script.

Using acpi-brightness

By default, brightness.sh uses acpi-brightness. If using it, you will have to change the line

readonly brightness=$HOME/usr/bin/brightness 

to point to the location of the acpi-brightness script.

Using xbacklight

If you wish to use xbacklight, you will need to replace the brightness function with something like

brightness() {
    local seconds=${1:-0}
    local steps=$((seconds * 100))
    xbacklight -time $((seconds*1000)) -set $percent
}

However, I have not tested this as xbacklight does not work on my system.

colorscheme.sh

Live-reload terminal colorscheme according to time of day.

By default, this switches between solarized light and solarized dark.

With URxvt

• Install urxvt-config-reload
• Copy Xresources.d to your ~/.Xresources.d
• Add #include ".Xresources.d/solarized" to .Xresources file
• (optional) Copy dircolors.ansi-dark from seebi/dircolors-solarized to ~/.dircolors.ansi-dark, and the same for dircolors.ansi-light

With other terminals

This currently only works for URxvt using urxvt-config-reload, though you may be able to rewrite the update_terminal() function to work with your terminal of choice.

Note that for best behaviour you need to change the colorscheme of running terminals, and also the global configuration for new terminals. Some terminals may automatically reload changes to their configuration, but in general to change running terminals you need to send control codes directly. Someone has already done this for Gnome terminal.
