weather_cli

Command line tool which presents weather data in a customizable format. This was originally created by following a series of tutorials on how to use click for handling command line arguments. I have since expanded upon and made this program into my own. Plan is to keep expanding upon it, and eventually add a 5-day forecast mode.

Pull requests, issues, comments and criticisms are more than welcome.

Demo

Short series of demo commands to show off a bit. Why not. The arguments can be specified in a variety of ways, as can be seen in the commands being entered. Full documentation for the available arguments can be found by passing the --help argument as noted in the installation instructions.

$ weather current Mars -Cthw --units imperial
Light rain | ↑34°F, 32.76°F, ↓32°F | 87%RH | NNW at 3.36mph
$ weather current Mars -Cthw -u standard --pretty long
Current conditions for Mars are
    Light rain at ↑274.26°K, 273.5°K, ↓272.59°K
      87%RH, winds NNW at 1.5m/s
$ weather current Mars -Cthw --units=metric -p verbose
Location: Mars
Conditions: Light rain
Temperature (High, Current, Low): ↑1.11°C, 0.42°C, ↓0°C
Relative Humidity: 87%RH
Wind (Direction, Speed): NNW, 1.5m/s

API Key

This program requires a free OpenWeatherMap API Key. Once you have your key, it may be passed into the program by either a configuration file or a command line argument. It is recommended to run weather in interactive mode and allow it to save the API key to configuration file. Using interactive mode will prevent you from entering your key into the terminal, which would leave it sitting in your history file for any with access to see.

# Install API key interactively
$ weather config
Please enter your OpenWeatherMap API key: YOUR_API_KEY [return]
# Install API key from command line
$ weather --api-key YOUR_API_KEY config

Obtain your API key here: https://openweathermap.org/appid

Installation

The install and use should be fairly simple. I don't totally know what I'm doing with setuptools but this works, and has been verified in local clones of this repo. If errors are encountered with these instructions, an issue or comment would be appreciated so I can fix it.

These instructions will install weather_cli into a virtual environment and create an executable, weather, within that environment. When called, that executable automatically enables the virtual environment, runs our program, and deactivates the virtual environment.

# Clone the repo
git clone https://github.com/ncdulo/weather_cli.git
cd weather_cli

# Create a new virtual environment, and enable it
python -m venv .env
source .env/bin/activate

# Update Pip & friends. Optional, but recommended
python -m pip install --upgrade pip setuptools wheel

# Install dependencies and create executable
pip install .

# Deactivate the virtual environment
deactivate

# Write your API key to configuration file interactively (recommended)
.env/bin/weather config
# -- or as a single command --
.env/bin/weather --api-key YOUR_API_KEY config

# Check use instructions
.env/bin/weather --help
.env/bin/weather config --help
.env/bin/weather current --help

# Optional, install symlink to executable within your $PATH
# ~/.local/bin must be in your system $PATH
ln -s `pwd`/.env/bin/weather ~/.local/bin/weather
# With the symlink in place, `weather` may be called from any location
# without typing the full path to the executable
