w3m and bash

You'll need: w3m, a tb_weather textbox and an internet-connection...

#!/bin/bash

if [ $# -ne 1 ]; then
        echo Usage: $(basename $0) city
        exit 1
fi

CITY=$1
FILE=$(mktemp)
w3m -dump "http://www.google.com/search?hl=en&q=${CITY}+weather" > $FILE
FIRST=$(grep -n iGoogle $FILE | awk -F ":" {'print $1'})
FIRST=$((FIRST+1))
LAST=$((FIRST+14))

sed -n -i "$FIRST,$LAST p" $FILE
TEMP=$(sed -n "1 p" $FILE)
WIND=$(sed -n "2 p" $FILE)
HUM=$(sed -n "3 p" $FILE)
SUN=$(sed -n "5 p" $FILE)
MIN_MAX=$(sed -n "6 p" $FILE | awk {'print $4$5" - "$1$2'})
MIN_MAX_TOMORROW=$(sed -n "9 p" $FILE | awk {'print $4$5" - "$1$2'})
SUN_TOMORROW=$(sed -n "8 p" $FILE)

echo 0 widget_tell tb_weather $SUN, $TEMP"("$MIN_MAX")  - " $WIND --- Tomorrow: $SUN_TOMORROW, $MIN_MAX_TOMORROW | awesome-client

rm ${FILE}

This is a "skeleton", you can modify this script.

bash script with wget for awesome 2.3

Here's another example:

#!/bin/bash
# this script is for awesome 2.3

LOCATION=KNYC
# station list at: http://www.rap.ucar.edu/weather/surface/stations.txt

while true; do
  if [ -S ~/.awesome_ctl.0 ]; then
    while true; do
      NEW=$(wget -qO- "http://www.weather.gov/data/current_obs/${LOCATION}.xml"\
        | sed -nr '/<(weather|temp_f)>/s/.*>(.*)<.*/\1/p' 2>/dev/null)
      if [ "x$NEW" != x ]; then
        NEW=$(echo "$NEW" | awk 'BEGIN{RS="";FS="\n"}{printf "%s %s\xb0",$1,$2}')
        echo -e "0 widget_tell mystatusbar weather text $NEW"
        echo "" # an empty line flushes data inside awesome
      fi
      sleep 600
    done | awesome-client
  else
    sleep 1
  fi
done

Perl

This is a Perl example for XML weather from http://weather.com, you can change it.

#!/usr/bin/perl
use XML::Simple;
use LWP::Simple;
use strict;
use warnings;
my $wea=XMLin(get('http://xoap.weather.com/weather/local/RSXX0091?cc=*&unit=m'));
my $tmp=$wea->{'cc'}->{'tmp'};
my $t=$wea->{'cc'}->{'t'};
$t=~s/Light Rain Shower/LRS/;
$t=~s/Light Rain/LR/;
$t=~s/Light Snow Shower/LSS/;
$t=~s/Light Snow/LS/;
$t=~s/Light Freezing Rain/LFR/;
$t=~s/Light/L/;
$t=~s/Cloudy/C/;
$t=~s/Windy/W/;
#$t=~s/and/&/;
$t=~s/Partly/P/;
$t=~s/Mostly/M/;
if (length($t)<=4) { $t=~s/ //g;}
my $bar=$wea->{'cc'}->{'bar'}->{'r'};
$bar*=0.75006; //converts to mmHg
$bar=sprintf("%d",$bar);
my $wind=$wea->{'cc'}->{'wind'}->{'s'};
$wind/=3.6;    //converts to m/s and rounds it to nearest integer.
$wind+=0.5;
$wind=sprintf("%d",$wind);
my $dir=$wea->{'cc'}->{'wind'}->{'t'};
print $tmp . "°C, " . $bar . " mmHg, " . $wind . " m/s, " . $dir . ", " . $t . "\n";

Yahoo Weather

Widget set, naughty notification, nice icon updating at forecast change and day/night cycle, localization support.

See https://github.com/copycat-killer/yawn

Google API + awful

I wrote a solution that makes a simple HTTP request to Google's Weather API based on postal code. See https://github.com/jesseadams/weather

Google API + libxslt + Naughty

Another solution, which shows Naughty notifications on mouse_hover at your widget (I use it for my text clock). Data is taken from Google API using query string, such as town name, postal code, etc. Futher reading at github

weather-util, awk, naughty and awful

This widget uses Naughty, awful, awk, the internet, and the commandline program "weather-util", which is also in the Debian, Ubuntu and Archlinux repositories. The widget creates a simple text box with the temperature, which you can hover over to get the full weather information.

Replace METARID with the metar ID of the weather station for your area. this is a four letter code like LYBE for Belgrade, Serbia. Stations list at [1]

--Create a weather widget

 weatherwidget = widget({ type = "textbox" })
weatherwidget.text = awful.util.pread(
  "weather -i METARID --headers=Temperature --quiet -m | awk '{print $2, $3}'"
) -- replace METARID with the metar ID for your area. This uses metric. If you prefer Fahrenheit remove the "-m" in "--quiet -m".
weathertimer = timer(
  { timeout = 900 } -- Update every 15 minutes. 
) 
weathertimer:add_signal(
  "timeout", function() 
     weatherwidget.text = awful.util.pread(
     "weather -i METARID --headers=Temperature --quiet -m | awk '{print $2, $3}' &"
   ) --replace METARID and remove -m if you want Fahrenheit
 end)

weathertimer:start() -- Start the timer
weatherwidget:add_signal(
"mouse::enter", function() 
  weather = naughty.notify(
    {title="Weather",text=awful.util.pread("weather -i METARID -m")})
  end) -- this creates the hover feature. replace METARID and remove -m if you want Fahrenheit
weatherwidget:add_signal(
  "mouse::leave", function() 
    naughty.destroy(weather) 
  end)
-- I added some spacing because on my computer it is right next to my clock.
awful.widget.layout.margins[weatherwidget] = { right = 5 } 

Now add the widget in with your other widgets, for example left of the text clock:

mywibox[s].widgets = {
   ...
   mytextclock,
   weatherwidget,
   ...
