[yalh76]

After @alexAubin integrated metronome 3.13.6 in YunoHost, we have an issue starting metronome:

I must've restarted it 20 times without that typo popping out -_-;

[maranda]

I'm not sure why but on my system it just doesn't throw a traceback, I don't even...

[yalh76]

Well after made the change 18b049b ...

but after removing ; Line 370, service starts

[maranda]

Yeah this is the problem apparently
i = function(); end is a valid statement in Lua5.2 while it traces in 5.1

[maranda]

@yalh76 unfortunately my development/production environments uses Lua 5.2 I didn't expect this to happen.

Metronome 3.13.6 retagged on the last commit :(

[yalh76]

well.. seems that YunoHost still use lua 5.1:

for information, i'm trying to make jitsi-meet work with metronome at https://github.com/YunoHost-Apps/jitsi_ynh/tree/fix_video
And for now there's something around Bosh metronome that doesn't work and I can't figure what...
But I'm like a Linux beginner and xmpp without knowledge

If you have time and willingness, maybe you could make it works....

[maranda]

Did you try to enable debug logs? See #518 also be ready to update Metronome manually to 3.13.7 there needs to be some changes, you made a little mess between Prosody and Metronome stuff I bet it doesn't work, I'll make a few pull requests to your app as well.
