Weather Forecast CLI Script

Overview

This script fetches and parses weather forecast data from Weather.com and formats it for display in various environments such as a terminal or Waybar, a status bar tool. It leverages pyquery for HTML parsing and provides detailed weather information, including hourly and daily predictions, formatted for ease of use.

Integration with Waybar

To integrate the script with Waybar:

1. Add a custom script module in Waybar's configuration:

   {
       "modules-left": ["custom/weather"],
       "custom/weather": {
           "exec": "weathergrabber --output waybar",
           "interval": 600
       }
   }
   

2. Reload Waybar to apply the changes.

Error Handling

• Validates weather_id and lang inputs.
• Handles HTTP errors gracefully, including 404 errors for invalid locations.
