lemmyverse: find communities from the command line
lemmyverse: search lemmy communities from the command-line. Thanks to the data HTTP API from lemmyverse.net! This is not really as polished as I like but, hey, in the interest of having a lively Lemmy I thought I’d share anyway :)
Usage
lemmyverse searches community names and descriptions using a regular expression:
<span style="color:#323232;">lemmyverse pattern

Why?
I run relatively slow hardware and I’m travelling in Bali, Indonesia at the moment. Loading lemmyverse.net in a web browser takes ages and gets the laptop fans spinning (it’s hot here!). So I had some fun creating a tiny command-line program to find Lemmy communities using classic UNIX tools awk(1), tr(1), grep(1) etc.
