autolight

Tiny Windows program that turns on/off dark theme at sunrise/sunset.

Installation

You can download the pre-built binary for the latest release on the GitHub releases page. You can put it anywhere you want on your computer. You can also build from source with cargo if you prefer (see Building below).

Running on startup

You will probably want to run the program at startup. To do so, add a shortcut to the executable (or the executable itself) in the "Start-up" folder:

1. Copy the executable (autolight.exe)
2. Windows + R and type shell:startup. This will open the "Start-up" folder.
3. In the new explorer window, right-click and select "Paste shortcut". On Windows 11, you might have to "Show more options" first.

Configuration

The configuration file is mandatory. It's loaded from %USERPROFILE%\.autolight.toml. This file is constantly watched and changes are applied automatically.

Example configuration

%USERPROFILE%\.autolight.toml

# Set this to `true` to terminate the process immediately
disable = false

# Set this to `false` to disable notifications
notifications = true

# Set this to `true` to have dark theme at day and light theme at night
# Why would anyone do this??
invert = false

# How often the program should force a time check (in seconds)
# The program might unsync with the system clock when the computer goes to sleep
# or hibernates. This setting will force a time check to resync it.
refresh_period = 60

# Required for the program to work: replace with YOUR coordinates
[location]
latitude = 48.956775
longitude = 2.463845

Building

autolight is written in Rust! Install it to build autolight from source.

cargo build

You can also build in release mode:

cargo build --release

Usage

Just run the executable. It runs in the background. Everything else happens in the configuration file.

To stop the process, set disable = true in the configuration file.
