Scrolling text

[paorie]

Is possible to use css animation for scrolling txt in custom module?
For example for a rss feeds reader.
tnks.

This probably won't fit every use case but, should it help anyone, I solved scrolling text in Waybar for my music player using a couple of scripts, custom modules and zscroll. zScroll itself hasnt been updated in a while (couple of years) but appears to remain functional.

Hopefully useful example:

In my use case, I have 2 scripts - one that contains commands to output the information I want to scroll on the bar, e.g:

current_song.sh

PLAYER_STATUS=$(playerctl -s -p cider status | tail -n1)
# Replace &'s in artist name/song title with +'s to avoid parsing issues
ARTIST=$(playerctl -p cider metadata artist | sed 's/&/+/g') 
TITLE=$(playerctl -p cider metadata title | sed 's/&/+/g')

if [[ $PLAYER_STATUS == "Paused" || $PLAYER_STATUS == "Playing" ]]; then
    echo "${ARTIST} - ${TITLE}"
elif [[ $PLAYER_STATUS == "Stopped" ]]; then
    echo "No Music Playing"
else
   echo "Music Player Offline"
fi

So this basically just outputs Artist Name - Song title if the defined player reports as online.

Then I pass this script into a second script for zscroll:

music_panel.sh

CURRENT_SONG="PATH/TO/SCRIPTS/current_song.sh"

zscroll -p " | " --delay 0.2 \
    --length 40 \
    --match-command "playerctl -p cider status" \
    --match-text "Playing" "--scroll 1" \
    --match-text "Paused" "--before-text ' ' --scroll 0" \
    --update-interval 1 \
    --update-check true $CURRENT_SONG &
wait

This will cause text to scroll when the combined artist/title name exceed the defined length value (e.g. 40 chars), and itll only scroll if the output of match-command returns playing. If it is paused, it will stop scrolling completely and whack a pause symbol before the output to denote that media is paused in Waybar. That then loops around the current song script, and in my waybar config I have this:

    "custom/media": {
      "escape": "true",
      "exec": "/PATH/TO/SCRIPTS/music_panel.sh",
      "format": "<U+F001> {}", 
      "max-length": 40,
      "on-click": "playerctl play-pause",
      "on-click-right": "playerctl stop",
      "on-scroll-down": "playerctl previous",
      "on-scroll-up": "playerctl next"
    },

Along with some CSS that styles it :)

@5ysk3y I tried this, but it doesn't seem to be working. The output of music_panel.sh is correct in the terminal, but no output is shown on the bar itself. What could be the issue?

[5ysk3y]

Hey! So this could be anything really.. if you're able to run the scripts independently via a terminal successfully then Waybar should execute them in the same way (assuming you're running Waybar as the same user).

If you run Waybar directly from a terminal so you can get the stdout/stderr stuff, is there anything in the output that shows a potential issue I wonder?

[gaganchandan]

Sorry about the late response. I tried this and it doesn't seem to output any error messages.

@gaganchandan try to remove interval field in waybar config!
