Custom component using wttr.in

[pauljacobson]

Hi there. I'd like to add a weather indicator to my lualine status bar as a custom icon. I'm not that familiar with Lua, so I'd appreciate some help with this. On the command line, I could run a command like curl wttr.in/Nuremberg?format=3 to produce a result like this:

Nuremberg: 🌦 +11⁰C

(source: wttr.in is a console-oriented weather forecast service that supports various information representation methods)

How would I write a custom component to invoke this in lualine? It seems like a simpler alternative to something like wyattjsmith1/weather.nvim: A simple plugin to display weather on nvim.

You could do something like this

_G.WeatherStatus = ''
local function update_weather()
  _G.WeatherStatus = vim.trim(vim.fn.system("curl -s wttr.in/Nuremberg?format=3"))
end

if _G.Update_weather_timer == nil then
  _G.Update_weather_timer = vim.loop.new_timer()
else
  _G.Update_weather_timer:stop()
end

_G.Update_weather_timer:start(0,             -- never timeout
                             10*60*1000,          -- repeat every 10 minutes
                             vim.schedule_wrap(update_weather))

require'lualine'.setup {
  sections = {
    lualine_c = {
        function () return _G.WeatherStatus end,
    }
  }
}
