weva

Note

This is a simple and opinionated hobby project for personal use.

An R package with a Rapp-powered command line interface (CLI) to generate a mini weather report for a UK postcode.

Using data from the:

• Open-Meteo API
• postcodes.io API via the {PostcodesioR} R package

Install

You can install the package from the R console.

pak::pak("matt-dray/weva")

Once the package is installed, you can install the CLI via the R console.

weva::install_cli()

Use

Run weva from a terminal with a valid UK postcode—the only required positional argument—to receive a tiny weather update and forecast.

weva wc2n5du

now 8.2°C ☀️ | +1h 7.6°C ☀️ 

The temperature values are styled with ANSI escape codes if your terminal supports them.

You can also supply options to:

• extend the 'later' forecast by a user-supplied number of --hours (shortcut -h)
• show interpreted --datetimes (-d) for each segment, rather than simple text
• show today's --extremes (-e) of temperature

weva "WC2N 5DU" -h 24 -d -e

2026-02-28 20:30 8.2°C ☀️ | 2026-03-01 21:00 11.1°C ☁️ | 2026-02-28 6.9°C to 10.7°C 

Run weva --help for further information.

CLI-first

This is a CLI-first package, but you can also use the exported get_weather() and prepare_report() functions in an R session.
