Description

Hyprshade takes full advantage of Hyprland's decoration:screen_shader feature by automating the process of switching screen shaders, either from a user-defined schedule or on the fly. It can be used as a replacement¹ for apps that adjust the screen's color temperature such as f.lux, redshift, or gammastep with blue-light-filter, which is installed by default.

Installation

Arch Linux

Use your favorite AUR helper (e.g. paru):

paru -S hyprshade

Or manually:

sudo pacman -S --needed base-devel
git clone https://aur.archlinux.org/hyprshade.git
cd hyprshade
makepkg -si

PyPI

If your distribution isn't officially supported, you can also install directly from PyPI with pipx²:

pipx install hyprshade

Usage

Usage: hyprshade [OPTIONS] COMMAND [ARGS]...

Commands:
  auto     Set screen shader on schedule
  current  Print current screen shader
  install  Install systemd user units
  ls       List available screen shaders
  off      Turn off screen shader
  on       Turn on screen shader
  toggle   Toggle screen shader

Commands which take a shader name accept either the basename:

hyprshade on blue-light-filter

...or a full path name:

hyprshade on ~/.config/hypr/shaders/blue-light-filter.glsl

If you provide the basename, Hyprshade searches in ~/.config/hypr/shaders and /usr/share/hyprshade.

Scheduling

Warning

For scheduling to work, systemd --user must have access to the environment variable HYPRLAND_INSTANCE_SIGNATURE.

Add the following line to hyprland.conf³:

exec-once = dbus-update-activation-environment --systemd HYPRLAND_INSTANCE_SIGNATURE

To have specific shaders enabled during certain periods of the day, you can create a config file in either ~/.config/hypr/hyprshade.toml or ~/.config/hyprshade/config.toml.

[[shades]]
name = "vibrance"
default = true  # will be activated when no other shader is scheduled

[[shades]]
name = "blue-light-filter"
start_time = 19:00:00
end_time = 06:00:00   # optional if more than one shader has start_time

For starters, you can copy the example config:

cp /usr/share/hyprshade/examples/config.toml ~/.config/hypr/hyprshade.toml

After writing your config, install the systemd timer/service user units and enable the timer unit:

hyprshade install
systemctl --user enable --now hyprshade.timer

Tip

Run hyprshade install every time you make changes to hyprshade.toml to keep the user units in sync.

Tips

You probably want the following line in your hyprland.conf:

exec = hyprshade auto

This ensures that the correct shader is enabled when you log in.

FAQ

How do I dismiss error messages from Hyprland?

hyprctl seterror disable. (Contrary to what the command may seem to imply, this does not disable any further error messages.) You may also use hyprctl reload.

I tried to copy something from the examples/ or shaders/ directory, but it's not working. What gives?

TL;DR: Hyprshade should work properly without needing to manually copy files. If activating a shader with hyprshade on does not work out of the box, feel free to open a bug report.

If you try to copy things from the main branch while you are using a stable release, it may not work properly. This repository has a single-branch development scheme, where all development is done on the main branch and stable versions are pinned with tags. The only exception to this is that updates to the README pertaining to unreleased features are kept on separate branches to avoid advertising features not present in any stable version.

If you'd like to try out unreleased features, you can use a development version of Hyprshade — currently, the only officially supported way to do this is to use the hyprshade-git AUR package.
