[hakerdefo]

(07 May 2017) Update  Begins:

Removed the dependencies on Perl and cURL.
Cleaned-up the script a bit.

Don't forget to read the set-up instructions posted down below if you are a new user

(19 November 2015) Update  Begins:

Starting from 9 October 2015 OpenweatherMap API requires a valid APPID for access. So you'll need to register at openWeatherMap and get your API key. It's simple and free plan is good enough for most cases. I've updated the script and instructions to reflect these changes. you can get the latest version of pmwf and read updated install instructions on GitHub page here,

pmwf on GitHub

I want to thank PackRat and ozitraveller for bringing this to attention. You guys rock

For this script to work you'll need to install one little tool first. Don't worry, it's easy. Just do this in your terminal,

Code Select Expand


sudo apt-get install jq


Next go to following website and search for the latitude-longitude of your place,

Tageo WorldWide Index

Open the script in your favorite text editor. Right at the beginning of the file you will find three empty variables 'latit', 'longi', and 'uneet'. You need to assign latitude of your location to the variable 'latit', longitude of your location to the variable 'longi' and your preferred units system to the variable 'uneet'. There are two main units systems in use. metric and imperial. Which one should you use? If you prefer to measure temperature in Celsius (Centigrade) & distance in Kilometres (km), use metric. And if you prefer to measure temperature in Fahrenheit & distance in Miles (mi), use imperial.

For example for a VSIDO user in London, UK it would look like this,

Code Select Expand


latit=51.500
longi=-0.117
uneet=metric


And for someone in New York, US it would look like,

Code Select Expand


latit=40.714
longi=-74.006
uneet=imperial


Save the script after making the necessary changes with the name 'pmwf' somewhere in your $PATH and 'chmod 755' it.
Whenever you wish to see some weather info for your place simply open terminal, type pmwf, hit Enter and you'll have current weather conditions with a 3 day weather forecast right in terminal.

Cheers!!!

This is a fantastic script hakerdefo... It will allow me to eliminate a nasty but effective plugin from Iceweasel

I appreciate your dedication and work on this, your skills are remarkable

I will also add this to VSIDO and reference this post for setup help

Thank you!

[PackRat]

Well done.

Q: API calls return an error 401
A: Starting from 9 October 2015 our API requires a valid APPID for access. Note that this does not mean that our API is subscription-only now - please take a minute to register a free account to receive a key.

We are sorry for inconvenience but this is a necessary measure that will help us deliver our services to you faster and more reliably.

For FOSS developers: we welcome free and open source software and are willing to help you. If you want to use OWM data in your free software application please register an API key and file a ticket describing your application and API key registered. OWM will review your request lift access limits for your key if used in open source application.

Hope that helps

A bit more...

How to use API key in API call

Description:

To get access to weather API you need an API key whatever account you chose from Free to Enterprise.

We keep right to not to process API requests without API key.

API call:

http://api.openweathermap.org/data/2.5/forecast/city?id=524901&APPID={APIKEY}
Parameters:

APPID {APIKEY} is your unique API key
Example of API call:

api.openweathermap.org/data/2.5/forecast/city?id=524901&APPID=1111111111

So this is why it stopped working... Thanks, ozi*

[PackRat]

Thanks ozi

[hakerdefo]

Thanks a metric ton PackRat and ozitraveller 
I've belatedly updated the things. Sorry for the delay

Script works as advertised.

After signing up, be sure to look at the My Services page of your account to see your limitations (calls per day etc  ....) - look to be pretty generous for just checking the weather; but running a conky on your desktop all day may cause some issues.

Got the API key ...

Not understanding this from the instructions:

Code Select Expand

Assign this key to 'apkey' variable in the file

Are we to add/create a variable apkey and then assign the value? What is the context?
