OpenWeatherMap

OpenWeatherMap is a haskell library to access https://openweathermap.org/api.

Requirements

OpenWeatherMap is written in Haskell with GHC. All required Haskell libraries are listed in openweathermap.cabal. Use cabal-install to fetch and build all pre-requisites automatically.

Command-line utility

The command-line utility openweathermap provides a means to get human readable weather infromation.

Usage

Usage: openweathermap ([-K|--api-key-file APIKEYFILE] | [-k|--api-key APIKEY])
                      ((-c|--city CITY) | --lat NUM --lon NUM) [-d|--debug]

Available options:
  -K,--api-key-file APIKEYFILE
                           Read API key from this file
  -k,--api-key APIKEY      API key
  -c,--city CITY           City name
  --lat NUM                Latitude in decimal degrees
  --lon NUM                Longitude in decimal degrees
  -d,--debug               Enable debug
  -h,--help                Show this help text

By default, openweathermap reads the API key from the $XDG_CONFIG_HOME/openweathermap/key file, where $XDG_CONFIG_HOME is typically ~/.config on Linux systems.

Examples

$ openweathermap -c norilsk
Norilsk,RU (69.35°, 88.2°): Clouds,  H 100 %,  P 753 mmHg,  T +4 °C,  ↓ 1 m/s

$ openweathermap --lat 55.7522200 --lon 37.6155600
Moscow,RU (55.75°, 37.62°): Clear,  H 45 %,  P 762 mmHg,  T +18..+21 °C,  → 4 m/s
