Go CMW

go-cmw is a cmw rewrite in Go.

Usage

go-cmw features a good command-line interface thanks to kingpin.v2.

A small terminal wrapper around the wttr.in weather endpoint.

On top of the following command-line flags, go-cmw can also take advantage of environment variables --expert-mode.

$ go-cmw --zero
Weather report: Paris

     \   /     Clear
      .-.      1..4 °C        
   ― (   ) ―   ↗ 11 km/h      
      `-’      10 km          
     /   \     0.3 mm

go-cmw makes it easier to integrate the weather with your favorite terminal multiplexer.

$ go-cmw --one-liner
Paris: ☀️ +4°C

Example configuration for tmux.

# Let us update sensibly every 30 minutes
set -g status-interval 1800

WEATHER='#(go-cmw --one-liner)'
set -g status-right '... $WEATHER ...'

Expert Mode

The commands labeled --expert-mode have special functionality attached to them. Some of them can be used as environment variables while others override go-cmw default functionality to provide the user with more flexible interface.

For more information about commands labeled --expert-mode

$ go-cmw --expert-mode

Reason

This project is a journey of learning Golang. If you would like to make an MR, please go right ahead, it would be a good learning process for me.
