Reddish Shift

A port of Redshift. Translated line by line with the help of C2Rust.

Reddish Shift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night.

Installation

Cargo

cargo install reddish-shift

Archlinux

paru -S reddish-shift
paru -S reddish-shift-bin
paru -S reddish-shift-git

Usage

For a quick start, run:

reddish-shift daemon --location LATITUDE:LONGITUDE

replace LATITUDE and LONGITUDE with your current geolocation.

To see all available commands:

reddish-shift -h

To see all available options for a given command (e.g. daemon):

reddish-shift daemon --help

Note that using --help instead of -h prints a more detailed help message.

A configuration file can also be used. It should be saved in the following location depending on the platform:

• Linux: $XDG_CONFIG_HOME/reddish-shift/config.toml or $HOME/.config/reddish-shift/config.toml if $XDG_CONFIG_HOME is not set or /etc/reddish-shift/config.toml for system wide configuration
• macOS: $HOME/Library/Application Support/reddish-shift/config.toml
• Windows: %AppData%\reddish-shift\config.toml

Building

Run cargo build --release --all to build these files:

• target/release/reddish-shift: the main program
• target/release/man1/: man pages
• target/release/completion/: various shell completion scrips
