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 :)

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.

See the man page:

LEMMYVERSE(1)               General Commands Manual              LEMMYVERSE(1)

NAME
     lemmyverse - find lemmy communities

SYNOPSIS
     lemmyverse pattern

DESCRIPTION
     lemmyverse finds Lemmy communities indexed by lemmyverse.net using the
     given regular expression as interpreted by grep(1).  Both the names and
     descriptions of the communities are searched.

     On first run, a local community database must be generated.  The full
     community index is downloaded from https://lemmyverse.net using curl(1),
     transformed, then stored in the user cache directory.  To regenerate the
     database, remove the file and run lemmyverse again.

FILES
     communities
             Community database from lemmyverse.net.

ENVIRONMENT
     lemmyverse uses the following environment variables:

     XDG_CACHE_DIR
             The directory to store the community database.  If unset,
             $HOME/.cache/lemmyverse is used.

EXAMPLES
     Find communities for the Plan 9 operating system:
           lemmyverse '(plan9)|(Plan 9)'

     List all communities from the instance lemmy.sdf.org:
           lemmyverse '@lemmy.sdf.org'

EXIT STATUS
     The lemmyverse utility exits 0 on success, and >0 if an error occurs.

    Will do. Hope they use it, having all that junk in the JSON file is no use to anyone.
