pmwf

pmwf displays current weather conditions with a 3 days weather forecast for almost any location in the world. pmwf shows information for following weather parameters,

Weather Condition
Minimum Temperature
Maximum Temperature
Atmospheric Pressure
Humidity
Wind Speed
Wind Direction

Why forecast for only 3 days you might wonder? Simply because no matter what they say, any forecast beyond next three days becomes less & less accurate. This is the reason why pmwf shows the current weather condition and forecast for the next three days.

Dependency:

jq - jq is like sed for JSON data. You can use jq to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. jq is available in the repositories of Debian, Ubuntu, Fedora, openSUSE, Arch (AUR), FreeBSD (FreshPorts), Solaris (OpenCSW), OS X (Homebrew). Linux and OS X binaries are also available from the Download section of jq website. If you decide to use the jq binary directly from the jq website you will have to rename it after downloading from jq-linux64 or jq-linux32 to simply jq. In case of OS X rename it to jq from jq-osx-amd64. Here is the link to the download page of jq,

Installation:

Installing pmwf is easy. Download pmwf-master.zip and extract it. Open the file pmwf in your favourite text editor. Right at the beginning of the file you will find four empty variables local_latitude, local_longitude, local_unit and api_key. You need to assign latitude of your location to the variable local_latitude, longitude of your location to the variable local_longitude and your preferred units system to the variable local_unit. Chances are that you don't know the latitude-longitude values for the place you live. No worries! It's easy. OpenStreetMap has geographic coordinate information of almost all the places on earth. Go to the following OpenStreetMap page and search for the latitude-longitude of your location,

OpenStreetMap

I've got latitude-longitude for my place but what is this units system I hear you say! Well, 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 Kilometers (km), use metric. And if you prefer to measure temperature in Fahrenheit & distance in Miles (mi), use imperial.

For example for someone in London, UK it would look like this,

local_latitude=51.500
local_longitude=-0.117
local_unit=metric

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

local_latitude=40.714
local_longitude=-74.006
local_unit=imperial

Next and final step is to get an API key from OpenWeatherMap. Don't worry it's simple and their free plan is good enough for our needs. Here is the link to the sign up page of OpenWeatherMap,

OpenWeatherMap Sign Up

After registration you'll get your unique API key. Assign this key to the api_key variable in the file.

Save the file after making the necessary changes.

Next copy the file pmwf to /usr/local/bin/ directory,

$ sudo cp pmwf /usr/local/bin/

Make it executable,

$ sudo chmod a+x /usr/local/bin/pmwf

If you have manually downloaded the jq binary from its website then do the following. Skip this step if you have installed jq using your distribution's package manager.

Copy jq binary file to /usr/local/bin/ directory,

$ sudo cp jq /usr/local/bin/

Make it executable,

$ sudo chmod a+x /usr/local/bin/jq

Usage:

Open terminal, type pmwf, hit Enter and you'll have current weather conditions with a 3 day weather forecast of your location right in terminal.
