[dev] wego: a weather app for the terminal written in go

[Markus Teich]

Heyho,

since I was tired of fetching lots of unneeded html and js and images just to
get a weather forecast, I wrote wego[0]. Comments welcome.

I did a similar thing a while ago in bourne shell. It's fragile, as 
shell scripts should be, and shouldn't be relied upon. But it's a 
nice example of another way to do this. It was never written for 
public use, but what the hell.

It uses Weather Underground, which means it has hourly info, and 
lots of other forecast stuff that the script is just ignoring for 
now. It also loads the json with the weather data without needing an 
API key, because that shit is for chumps.

Oh, and its output is far, far more basic than Markus'.

Attached.
#!/bin/sh
usage=$0 location

test $# -eq 0  echo $usage  exit 1

loc=`echo $@ | sed 's/ /+/g'`
resp=`curl 
'http://www.wunderground.com/cgi-bin/findweather/hdfForecast?query='$loc`

# build actual json url
key=`echo $resp | awk '/\tk:/ {print $2}' | sed s/[',]//g`
locationcode=`echo $resp | awk '/\tzmw:/ {print $2}' | sed s/[',]//g`
json=`curl 
http://api-ak.wunderground.com/api/${key}/forecast10day/hourly10day/labels/astronomy10day/lang:EN/units:metric/v:2.0/bestfct:1/q/zmw:${locationcode}.json`

usefuljson=`echo $json | jq 
'.forecast|.days|.[]|.hours|.[]|{epoch:.date.epoch, temperature, pop, snow, 
humidity, condition}'`

echo $json | jq -r '.current_observation.station|.id,.name,.city'

echo $usefuljson | sed 's///g; s/,//g; s/: /:/' | while read line; do
test $line = }  printf '\n'  continue
test $line = {  continue

epoch=`echo $line | awk -F : '($1 == epoch) {print $2}'`
if test $epoch !=   test $epoch != null; then
datestr=`printf @%s $epoch`
date=`date --date=$datestr +'%a %d, %R'`
oldcurday=$curday
curday=`echo $date | awk '{print $1}'`
test $curday != $oldcurday  printf '\n'
printf %s -  $date

echo $line | awk -F : '{

Looks great! I will give it a try in the next few days.

I forgot to mention it depends on curl and jq. Any bourne shell 
should work though; I don't believe in bash.

When I tried to run it, it would just print Malformed response. I
added a line to dump the URL to stderr before that and tried to get it
with wget, and the response I get is 403 Forbidden. What am I doing
wrong?

Ciao,
Markus

Oh yes, one third of my SLOC are the ascii icons and nearly another third is for
the output formatting… :/

For me, SSL support was more important than not having to use an API key. I did
not find a service providing both.
