himawari

GO version of himawaripy https://github.com/boramalper/himawaripy

himawari is a golang project that fetches near-realtime (10 minutes delayed) picture of Earth as its taken by Himawari 8 (ひまわり8号) and sets it as your desktop background.

Set a cronjob that runs in every 10 minutes to automatically get the near-realtime picture of Earth.

install

go get github.com/LiuPai/himawari/cmd/himawari

Usage

You can configure the level of detail, by modifying the parameter. You can set the parameter level to 4, 8, 16, or 20 to increase the quality (and thus the file size as well). Please keep in mind that it will also take more time to download the tiles.

You can also change the path of the latest picture, which is by default /tmp/himawari.png, by changing the output parameter.
