obsession with modul checker

[HeikoGr]

I am obsessed with the modul checker on the MagicMirror² 3rd Party Modules list…

so, i asked github copilot to implement an instant modul checker script.

technically it clones the modul checker repo, and the local files to /tmp/mm-modul-checker… and installs the deps.

you can find it in recently most active repo:
https://github.com/HeikoGr/MMM-Webuntis/blob/master/scripts/magicmirror-check.mjs

run it: node scripts/magicmirror-check.mjs and you will get:

> mmm-webuntis@0.6.1 check:mm
> node scripts/magicmirror-check.mjs

🔍 Setting up MagicMirror checker...
Fetching checker repository (git-free) via `degit` (first time only)...
📦 Installing dependencies...
✓ Copying local files (excluding node_modules)...
✓ Checking MMM-Webuntis (including uncommitted changes)
🔎 Running full module checks...
🔍 Running ESLint check on package.json...

@HeikoGr said in obsession with modul checker:

node scripts/magicmirror-check.mjs

I tried it, but get an error

❌ Error: Cannot copy a FIFO pipe: cp returned EINVAL (cannot copy a FIFO pipe: /tmp/mm-module-checker-MagicMirror/modules/MagicMirror-----MagicMirrorOrg/.lgd-nfy0) /tmp/mm-module-checker-MagicMirror/modules/MagicMirror-----MagicMirrorOrg/.lgd-nfy0

[HeikoGr]

you need to put the script inside the folder of the module you want to check - not the MagicMirror folder itself

[htilburgs]

@HeikoGr
So it is not possible to check all the modules in one run?
I have to do it for each module?

[HeikoGr]

@htilburgs my main objection was to support the module development. so yes, at the moment it’s a per module check,

[htilburgs]

@HeikoGr
Oké, clear. Thanks for the quick replys

[KristjanESPERANTO]

@heikogr Nice idea! I’ll take a closer look.

[HeikoGr]

@htilburgs now it should work for all installed modules

[htilburgs]

@HeikoGr
So now I put It in the MagicMirror folder?

[HeikoGr]

@htilburgs the script looks if it is under an magicmirror/modules folder and takes this as root folder for modules.
otherwise it will take /opt/magic_mirror/modules

if your setup is different you need to adapt the script.

the script itself can be placed independently

@HeikoGr
Oké, thank you

[sdetweil]

@HeikoGr the script could check and provide a parameter

I gave it a testrun and it gave me an error

 Running checks for 17 modules...

Any idea?

[htilburgs]

After installing tsx (npm install tsx@4.21.0) it gave me a new error:

@htilburgs i guess your modules are missing the minimal requirements for MagicMirror modules in the packages.json file.

I managed to lower the requirements…

[KristjanESPERANTO]

@htilburgs In case you haven’t seen it yet: You can also check https://modules.magicmirror.builders/result.html#MMM-MyHomeWizard-by-HTilburgs. Thats the result of the checks on what you pushed to GitHub.

@KristjanESPERANTO
Thanks, I didn’t know about this.
This is the result of running the script?

[HeikoGr]

@htilburgs it‘s the original script. My script only tries to run this script locally on demand

@HeikoGr 👍
