powerline-owmweather 🌦

A light-hearted Powerline segment for fetching and showing the weather in the current location (either by IP geolocation or by setting a location, see Configuration below).

Keep in mind that powerline_owmweather is in early, rapid development stage so its API/configuration format may change.

Motivation

The built-in weather segment is using Yahoo Weather API which is no longer available so I decided to create an almost drop-in replacement using OpenWeather.

Requirements

• Powerline
• A (free) OpenWeather account and API key with the "Current Weather Data" plan enabled.

Installation

pip install powerline-owmweather

Activiation

The very minimum required to activate the segment is to add the following to your theme JSON:

{
   "function": "powerline_owmweather.weather",
   "args": {
       "openweathermap_api_key": API_KEY
   }
}

and the following to your colorscheme JSON (the colors can be customized):

"groups": {
      ...,
      "owmweather": {
          "fg": "gray9",
          "bg": "gray2",
          "attrs": []
    }
}

Configuration and Customization

The following optional args are available:

Argument	Type	Description	Default
condition_as_icon	boolean	If true, condition will be displayed as an icon (if one of known conditions). If false condition will be displayed as a string	true
humidity_format	string	A Python format string that accepts humidity as an argument	"{humidity:.0f}"
location_query	string	Location in format CITY, 2-LETTERS-COUNTRY-CODE	Retrived using IP geolocation
post_condition	string	String to append after condition	""
post_humidity	string	String to append after humidity	""
post_location	string	String to append after location	""
post_temp	string	String to append after temp	""
pre_condition	string	String to prepend before condition	" "
pre_humidity	string	String to prepend before humidity	" "
pre_location	string	String to prepend before location	" "
pre_temp	string	String to prepend before temp	" "
show	string	Comma-separated string specifies what data to show. Can include "condition", "humidity", "location", "temp". See Highlight Groups	"temp"
temp_format	string	A Python format string that accepts temp as an argument	"{temp:.0f}"
ttl_in_minutes	integer	Time in minutes for which location and weather are cached. Warning: The lower the value the slower your terminal will be	60
units	string	Temperature units. Should be one of "C", "F", "K"	"C"

Highlight Groups

Every data in "show" is displayed in its own segment with its own highlight group, meaning it can be styled independently in your colorscheme JSON. Each highlight group is composed of owmweather_{data_name}, for example:

"owmweather_condition": {
    "fg": "gray6",
    "bg": "gray3",
    "attrs": []
},
"owmweather_temp": {
    "fg": "gray9",
    "bg": "gray2",
    "attrs": []
}

"pre_{data_name}" and "post_{data_name}" can also be customized using "owmweather_pre_{data_name}" and "owmweather_post_{data_name}" highlight groups.

If a specific highlight group is not defined then the style of "owmweather" group will be used.
