dayglance

A terminal dashboard written in Rust that shows the current time, a monthly calendar, this week's weather forecast, and upcoming public holidays — all in one glance.

Features

• Time & date — timezone-aware, derived from your location
• Monthly calendar — current month with today highlighted
• 7-day weather forecast — powered by Open-Meteo (free, no API key)
• Upcoming public holidays — fetched from Nager.Date based on your country
• Location cache — detected once via IP, saved to ~/.config/dayglance/config.toml

Usage

cargo run              # full dashboard (7-day weather, 6 upcoming holidays)
cargo run -- s         # short view    (3-day weather, 3 upcoming holidays)
cargo run -- short     # same as above

First run

On the first run, dayglance auto-detects your location via IP and asks you to confirm:

Detected location: Seoul, South Korea. Use this? [Y/n]:

Press Enter to accept, or type n and enter a city name manually. The answer is cached — subsequent runs start instantly.

To reset the location, delete ~/.config/dayglance/config.toml.
