I broke something

Hi everyone,
Was cleaning my module directory, I think I deleted something I shouldn’t have…
My mirror starts but only shows the clock.
The RemoteControl is ok except the “hide and show modules” part that asks to check the MM logs for more details.
That’s what I get :

PM2            | App [MagicMirror:1] exited with code [1] via signal [SIGINT]
PM2            | App [MagicMirror:1] starting in -fork mode-

I tried to npm install all my modules again but still the same.
Got an idea ?

Well, I did a fresh reinstall, it took me about 2 hours but it’s approximately working again

BKeyport

I moved my personal configs to another directory and symlinked them in their proper places.

This gives me a guide to get up and running after doing something stupid… Takes reinstall time from several hours to about 30 minutes.

@BKeyport said in I broke something:

symlink

I’m not sure to exactly get what a simlink is, what’s the difference with a simple copy ?

sdetweil

@killerjoe34 linux file systems give you the ability to create a file as a LINK to another file somewhere else…

so you only have one copy, but multiple instances… changing the root file makes it look like all the linked files changed too

see the ln command

Ok, I read the man page but still don’t get it, even in french
You’re saying that if the root file is modified, it also modifies the linked one(s) or does it make another copy ?
Cause it would be perfect in that case, keeping track of every modification to be able to step back.

Thanks for your explanations

sdetweil

@killerjoe34 no, the link makes it look like all the secondary files ARE the root file. so actually changing ANY changes them all, there is ONLY one actual file. but erasing the linked file does NOT erase the root file.

try this

mkdir ~/foo
mv ~/MagicMirror/config/config.js foo
cd ~/MagicMirror/config
ln -s ~/foo/config.js config.js

now you have your file in ~/foo
but it LOOKS like it is also in ~/MagicMirror/config

edit one, change the date/time format
restart MM
voila
edit the other one and change it back
restart MM

Wow great
Thanks a lot, I’ll use that !

sdetweil

@killerjoe34 you can also link folders

if you do (in the config folder where I just set a link)

ls -laF

will show u the file is linked, and where to

Ok, I’ll have a look at that, thx again !
