been playing with making fun scripts using charm CLI’s gum library :P
one that gets lyrics from an open lyrics database’s API and accepts input for artist & song names: https://asciinema.org/a/697860
and one that uses a user-provided last.fm API key to pull what’s currently playing or what last played on your account :) https://asciinema.org/a/697874

(#buulkxq) @kat@yarn.girlonthemoon.xyz both scripts are here under the names ‘getlyr’ and ‘now playing’ if you wanna try them out yourself, just make sure you have gum installed (also curl and jq but most people have those i think) https://git.sr.ht/~chasinglightning/dotfiles/tree/main/item/home/.local/bin

(#buulkxq) @kat@yarn.girlonthemoon.xyz definitely a fun way to get better at bash scripting by hand (AKA learn how it works besides the extreme basics i know) and use gum to make them cute too

(#buulkxq) @kat@yarn.girlonthemoon.xyz To improve you shell programming skills, I highly recommend to check out shellcheck: https://github.com/koalaman/shellcheck It points out common errors and gives some suggestions on how to improve the code. Some details in shell scripting are very tricky to get right at first. Even after decades of shell programming, I run into “corner cases” every now and then.
E.g. in getlyr’s line 7 it warns:
echo -e $(gum style --italic --foreground "#f4b8e4" "'$artist', '$song'")

Most likely not all that problematic in this application, but it’s good to know about this underlying concept. Word splitting is basically splitting tokens on whitespace, this can lead to interesting consequences as illustrated by this little code:
$ echo $(echo "Hello World")
Hello World
$ echo "$(echo "Hello World")"
Hello World
In the first case the shells sees two whitespace-separated tokens or arguments for the echo command. This basically becomes echo Hello World. So, echo joins them by a single space. In the second one it sees one argument for the echo command, so echo simply echos this single argument that contains three spaces.
