v0.6.0 event vars missing \n delimiter

[moodeaudio]

Hi,

I'm processing the track metadata in a bash event script and noticed that the env vars ARTISTS, ALBUM_ARTISTS and COVERS which should be \n delimited according to the wiki don't appear to contain these delimiters but instead are delimited by space.

Config
pi-5
PiOS bookworm
librespot v0.6.0
moOde 9.1.4 (latest)

Event script

if [[ $PLAYER_EVENT == "track_changed" ]]; then
	echo -e $ARTISTS > /home/pi/tim.txt
	echo -e $ALBUM_ARTISTS >> /home/pi/tim.txt
	echo -e $COVERS >> /home/pi/tim.txt
fi

Example Output
The two artists are: "softy" and "Dimension 32" and appear as "softy, Dimension 32" in the IOS app. The album artist is "softy".

pi@moode9:~ $ cat ./tim.txt
softy Dimension 32
softy

Output should be

pi@moode9:~ $ cat ./tim.txt
softy
Dimension 32
softy

Sorry for the late response, but I can confirm the behavior on my side. Interestingly enough tho the string that is set as env_var has a \n to delimit the artists/cover but later in the env_var it's a whitespace. Just out of curiosity, this did work at some point right? I would suspect so, but just wanted to clear that up first :)

Ah it seems like a pretty simple fix to your script. It seems to work when you wrap the env_vars with quotation marks and then echo seems to parse it correctly. I tested the following with zsh and it has some interesting behaviors... not what you might expect. Let me know if that worked for you :D

Warning

Doesn't work

TEST=some\ntesting; echo -e $TEST
somentesting

Tip

Works

TEST="some\ntesting"; echo -e $TEST
some
testing

Warning

Funnily enough also doesn't work

TEST=some\ntesting; echo -e "$TEST"
somentesting
