Arduino: Examples command displays an empty tab

[Kurolox]

Basically, whenever I try to use the Arduino: Examples command it displays an empty tab like this.

The arduino path in the settings is set up as "arduino.path": "/usr/share/arduino", and the examples are in /usr/share/arduino/examples. the Arduino IDE lists the examples correctly.

What is your operating system? Is it Ubuntu?

[Kurolox]

Arch Linux. Here's the output of uname -a.

The examples work when pointing arduino.path to an Arduino IDE downloaded from the official website.

When the Arduino IDE installed by Arch's package manager is used (/usr/share/arduino), the extensions tries to access /usr/share/arduino/libraries and throws an exception because that directory does not exist.

If you create an empty libraries directory in /usr/share/arduino, vscode correctly shows the built-in examples.

That workaround didn't work for me. I've created the folder by running sudo mkdir /usr/share/arduino/libraries, and rebooted the computer afterwards just to be sure, but the examples tab is still empty.

Here's the output of ls -l /usr/share/arduino, just so you can see that the folder is actually there.

Hmm, your folder looks exactly like mine.

Can you take a loot at the developer console (Help -> Toggle Developer Tools) to see what error you are getting when opening the Arduino examples tab?

Here is what I get when the libraries directory does NOT exist: https://i.imgur.com/WE7oYnn.png

Well, this is bizarre. It seems like it's looking for ~/Arduino/libraries for some reason: https://i.imgur.com/lGKHX8W.png

I have explicitly configured vscode to use the /usr/share/arduino path with "arduino.path": "/usr/share/arduino", but for some reason it's looking in there. I don't even have an Arduino folder in home.

Any idea about what could be happening?

I can confirm that creating ~/Arduino/libraries fixes the problem, but I wonder why it's even looking for that folder in the first place.

[jhenninger]

Afaik the offical Arduino IDE creates that folder.

[Kurolox]

That still doesn't explain why it's looking for the folder in that path when I've explicitly set it up otherwise on the vscode settings, though. It's still looking at the default path for some reason. Could you share your vscode config (at least the config regarding this plugin) to check if there's any difference?

[jhenninger]

I haven't changed any settings of the plugin aside from the path. I guess the extension just looks in multiple locations for libraries, examples etc. but doesn't handle missing directories gracefully.
