Weather query

Short and sweet weather API query tool written in Go. It employs both GeoNorge (Kartverket) and YR weather APIs in order to allow fast weather lookup using only a recognizable place name in the Kingdom of Norway.

Build

The compiled version is notably faster (e.g 0,168s v. 0,566s). To compile a binary simply run:

  go build weather_query.go

There are also semi-current binaries for Linux, Mac and Windows 64-bit in the /dist folder.

Usage

  $ ./weather_query 
  Usage: ./weather_query <place>
  Error: Location string argument missing. Use any place in Norway.

for example:

  $ ./weather_query Tønsberg
  Current weather in:           Tønsberg
  Coordinates (long, lat):      10.40764, 59.26751
  Observation timestamp:        2021-10-26 18:00:00 +0000 UTC
  Temperature (celsius):        7.3°C
  Temperature (fahrenheit):     39.3°F
  Airpressure at sea level:     1009.4 hPa
  Current humidity:             76.3 %
  Wind speed:                   2.8 m/sec

Short and sweet. weather_query will pick the first hit if several.

TODO

• Put repetetive tasks in functions, esp. API query, cf. stackoverflow.com/a/31129967

• Handle errors gracefully, e.g. when I query non-existent or unknown place name:

  $ go run weather_query.go Tolkien
  panic: runtime error: index out of range [0] with length 0

A useful error message is better than a panic.

• Could add a parenthesis on tstamp (N <time unit> ago)

• Add an array of postal codes

• Use argument flags, to allow for: --usage, --coord (don't lookup place name), --temperature ops.
