Spolyfy is a Polybar module written in Rust that provides current Spotify song's title, previous, next and play-pause buttons.
You can install Spolyfy using Cargo with the following command:
$ cargo install spolyfy
You can setup the modules like this
[module/spotify-current]
type=custom/script
exec = spolyfy -c 35
exec-if = [ $(spolyfy -l) = "yep" ]
[module/spotify-previous]
type=custom/script
exec = spolyfy -a ;This command prints a Nerd Font icon
exec-if = [ $(spolyfy -l) = "yep" ]
click-left = spolyfy -p
[module/spotify-play-pause]
type=custom/script
exec = spolyfy -x ;This command prints a Nerd Font icon
exec-if = [ $(spolyfy -l) = "yep" ]
click-left = spolyfy -s
[module/spotify-next]
type=custom/script
exec = spolyfy -b ;This command prints a Nerd Font icon
exec-if = [ $(spolyfy -l) = "yep" ]
click-left = spolyfy -n
Then you can add the modules in your bar anyway you want
Example
[bar/mybar]
modules-center = spotify-current spotify-previous spotify-play-pause spotify-next
Im not very experienced in Polybar nor Rust, so please feel free to report any bug or improvement to the code ;)
