wego

wego is a weather client for the terminal.

Features

• show forecast for 1 to 7 days
• multiple backends: openweathermap, weatherapi, open-meteo, smhi, caiyun, worldweatheronline, pirateweather, and json
• multiple frontends: ascii-art-table (default), emoji, markdown, and json
• displayed info:
  • temperature range (felt and measured)
  • windspeed and direction
  • viewing distance
  • precipitation amount and probability
  • humidity
• unit systems: metric, imperial, si, metric-ms
• disk caching of weather data with configurable TTL (--cache-ttl)
• multi language support
• config file for default location which can be overridden by commandline
• automatic config management with ingo
• built-in man page (wego --man)
• composable via JSON: pipe data between the json backend and json frontend

Dependencies

• A working Go 1.20 environment
• utf-8 terminal with 256 colors (for ascii-art-table and emoji frontends)
• A monospaced font containing all the required runes (e.g. dejavu sans mono)
• An API key for most backends (see Setup below; open-meteo and smhi are free and keyless)

Installation

Check your distribution for packaging:

To directly install or update the wego binary from Github into your $GOPATH as usual, run:

go install github.com/schachmat/wego@latest

Setup

0. Run wego once. You will get an error message, but the wegorc config file will be generated in your $XDG_CONFIG_HOME/wego/ directory (or the OS-equivalent location returned by os.UserConfigDir(), e.g. ~/.config/wego/wegorc on Linux).
1. Choose a backend and configure it (see below). Then run wego again.
2. You may want to adjust other preferences like days, units and …-lang as well. Save the file.
3. Run wego once again and you should get the weather forecast for the current and next few days for your chosen location.
4. If you’re visiting someone in e.g. London over the weekend, just run wego 4 London or wego London 4 (the ordering of arguments makes no difference) to get the forecast for the current and the next 3 days.

The config file is resolved in the following order:

1. $WEGORC environment variable (highest precedence).
2. $XDG_CONFIG_HOME/wego/wegorc (or OS equivalent via os.UserConfigDir()), if it exists.
3. $HOME/.wegorc (legacy location, for backward compatibility), if it exists.
4. If none of the above exist, a new config file is created at $XDG_CONFIG_HOME/wego/wegorc.

JSON file — read weather data from a local JSON file (useful for testing or offline use):

backend=json
location=/path/to/weather.json

Frontends

Select a frontend with the --frontend flag or by setting frontend=… in .wegorc.

Frontend	Description
ascii-art-table	Default. Classic colored ASCII art table.
emoji	Compact emoji-based display.
markdown	Markdown table output.
json	JSON output, suitable for piping to other tools.

Example: wego --frontend emoji London

Color Configuration

Both ascii-art-table and emoji frontends display temperatures and wind speeds in color by default. To disable colors:

• Pass --monochrome as a flag, or add it to .wegorc to make it permanent:

  monochrome=true
  

• Set the NO_COLOR environment variable (see no-color.org) to disable colors without changing the config:

  NO_COLOR=1 wego
