weather app for the terminal

wego is a weather client for the terminal.

Screenshots

Features

  • show forecast for 1 to 7 days
  • nice ASCII art icons
  • displayed info (metric or imperial units):
    • temperature range (felt and measured)
    • windspeed and direction
    • viewing distance
    • precipitation amount and probability
  • ssl, so the NSA has a harder time learning where you live or plan to go
  • multi language support
  • config file for default location which can be overridden by commandline
  • Automatic config management with ingo

Dependencies

  • A working Go 1.5 environment (You can use goenv if your distribution does not support Go 1.5 yet)
  • utf-8 terminal with 256 colors
  • A sane monospaced font containing all the required runes (I use dejavu sans mono)
  • An API key for the backend (see Setup below)

Installation

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

go get -u github.com/schachmat/wego

Setup

  1. Run wego once. You will get an error message, but the .wegorc config file will be generated in your $HOME directory (it will be hidden in some file managers due to the filename starting with a dot).
  2. With a forecast.io account (new default)
      backend=forecast.io
      location=40.748,-73.985
      forecast-api-key=YOUR_FORECAST.IO_API_KEY_HERE
    
  3. With an Openweathermap account
    • You can create an account and get a free API key by signing up
    • Update the following .wegorc config variables to fit your needs:
      backend=openweathermap
      location=New York
      owm-api-key=YOUR_OPENWEATHERMAP_API_KEY_HERE
    
  4. With a Worldweatheronline account
    • Worldweatheronline no longer gives out free API keys. #83
    • Update the following .wegorc config variables to fit your needs:
      backend=worldweatheronline
      location=New York
      wwo-api-key=YOUR_WORLDWEATHERONLINE_API_KEY_HERE
    
  5. You may want to adjust other preferences like days, units and …-lang as well. Save the file.
  6. Run wego once again and you should get the weather forecast for the current and next few days for your chosen location.
  7. 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. Unfortunately that does not currently work with the forecast.io backend, as it only supports latitude,longitude location specification.

You can set the $WEGORC environment variable to override the default config file location.

  • Incorrect table alignment under some terminal emulators due to double-width characters

    Incorrect table alignment under some terminal emulators due to double-width characters

    This is a followup to discussion on Alacritty commit 3ad68699 (Alacritty is a "cross-platform, GPU-accelerated terminal emulator").

    The problem is that, in some terminals, wego 2.0 table alignment suffers from the width of the unicode characters used (cloud, sun, etc). See for yourself:

    • GNOME Terminal:
      selection_002
    • Alacritty:
      selection_001

    To me that looked like a bug in Alacritty, but its main developer, @jwilm, comments that:

    I believe this is a bug with wego. They don't account that terminals may display a cloud as 1 or 2 columns. GNOME Terminal appears to think the cloud icons are only single width. Alacritty (correctly) handles them as double width. We are using the Unicode 9 definitions for wide chars, so that may account for the difference.

    In the wego emoji frontend,

    ret = append(ret, fmt.Sprintf("%v %v %v", cur[1], icon[0], c.formatTemp(cond)))
    

    you can see that there's a space after the icon in the Sprintf format string. It's not visible in GNOME Terminal because it's under the emoji. You can see it in Alacritty because we account for the double width characters.

    wego should be using the goto functionality of terminals to handle both cases.

  • ingo dependency not properly installed on homebrew go

    ingo dependency not properly installed on homebrew go

    You should really add to README under dependencies that ingo needs to be installed since it says nowhere that you must install ingo prior to installing wego:

    Install ingo prior to installing wego go get -u github.com/schachmat/ingo

    You also may want to clue users in to how to install go also (prior to installing ingo obviously):

    Mac OS X install of go using homebrew brew install go

    The readme is really confusing and results in a nasty error message and no clues in the error message that the reason it's not working is because ingo wasn't installed prior to installing wego...also when you run wego on first run without ingo installed it says nothing about the configuration file not being automatically generated and nothing about ingo not being installed so it's super confusing...should probably add a check on execute of wego that verifies ingo is installed.

  • iTerm box-drawing character missalignment

    iTerm box-drawing character missalignment

    Hi,

    sorry I didn't necessarily wanted to open an issue for it but my ascii art looks a bit weird. At least it does not look the way it looks in the screenshot of your installation instructions. Does it only work with specific fonts? I can't really see the clouds its just some slashes and dots. Same with the sun.

    thanks in advance kevin

  • Move config file to $XDG_CONFIG_HOME

    Move config file to $XDG_CONFIG_HOME

    The standard location for config files is not $HOME but $XDG_CONFIG_HOME, which default to $HOME/.config/.

    More info:

    • https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html
    • https://wiki.archlinux.org/index.php/XDG_Base_Directory_support

    You will find plenty of projects have moved their config files to $XDG_CONFIG_HOME to comply with this standard. I think wego should do the same and move the config to something like $XDG_CONFIG_HOME/wego/wegorc.

    Beyond standard compliance, this helps a lot users who want to sync config files between several computers. Instead of having files scattered all over $HOME, they are all tidy and neat in one place.

  • forecast.io backend progress

    forecast.io backend progress

    I pushed the first version of the forecast.io backend to the forecast.io branch. Some points need to be adressed before merging into master:

    • [x] double-check to implement the maximum possible of the iface in condition
    • [x] min- and max-temperature for daily data
    • [x] astronomy for daily data
    • [x] remove debugging code and commented out code
    • [x] restrict return value of Fetch to the requested number of days
    • [x] add language flag
    • [x] add call to time machine api to get "forecast" for the passed time of the current day
    • [ ] (optional) is there a better possibility to specify location other than a lat,lon string?
  • Added support for flags

    Added support for flags

    So far, you use wego 1 Paris to fetch weather data for Paris for 1 day. With this commit, you use wego -days 1 -city Paris to fetch the same information. Benefit of this approach is that (1) it prints help message when you do wego -h (2) it is clear what data you're seeking.

    PS - I really loved wego. And I am learning golang. So I felt like adding this simple support for flags as a part of learning and contributing back to wego. :smiley:

    Metric wind speeds in m/s?

    A number of countries in Europe use meters per second for wind speeds, rather than kilometers per hour. Would it be possible to have another wind speed option that could display wind speeds in m/s? This appears to already be an option available on darksky.net.

  • Wind Direction Letters

    I added these two changes to my fork of wego so I could get letters instead of the arrow icons for wind direction. Please add these changes if they're a good fit.

    Thanks for wego!

  • "Could not find selected backend 'forecast.io'?"

    Trying to get WeGo on Windows 10....So far, I have installed NixOS and WSL2 via Powershell and when I run:

  • Minor changes in ascii art

    Minor changes in ascii art

    • Make sun in "partly cloudy" less irregular

    • Make "sunny" more intense

      I have noticed that when there's a lot of "sunny" and "partly cloudy" in the output, it's not apparent at first sight which is which. This should make the "sunny" icon more intensely yellow, and therefore more discernible.

    • Make dark grey and dark blue a bit ligther

      Previous colors were not readable against some background colors, e.g. #0a3947. New colors are more readable but should be still sufficiently darker than the ones used for light clouds (250) and light rain (111).

    Here's a screenshot of the "too dark" problem on my terminal: Screenshot from 2021-09-03 17-16-38

    Feel free to pick just some changes if you don't like one of the others.
