How to debug this CopyQ 'join' command?

[DeanintheMachine]

Happy CopyQ user here, getting my feet wet with commands. I pasted this example join command into my CopyQ version 8.0.0 on linux: https://github.com/hluk/copyq-commands/blob/master/Application/join-selected-items.ini

And here is the commands's code:
copyq:
const separator = '\n';
var sel = new ItemSelection().current();
const texts = sel.itemsFormat(mimeText);
sel.selectAll();
add(texts.join(separator));
sel.invert();
selectItems(sel.rows()[0]);

The command does run, but instead of showing the joined entries, it shows this:
ScriptableByteArray(0x55a84559d2f0)
ScriptableByteArray(0x55a84559c600)

I am guessing the culprit is the itemsFormat(mimeText) call? I dug a bit into the code, but the data structures are way over my head.

Would anyone have an idea what may be going wrong? Thanks!

I think it was fixed in version 9.0.0. Can you verify?

The same problem on Arch Linux (CopyQ version 9.1.0):

ScriptableByteArray(0x5787a8c5fd80)
ScriptableByteArray(0x5787a8c5b2a0)

after join command

Oh, I can reproduce this on Qt 5 build of the app. The Qt 6 version does not have the problem. 🤔

It is probably not worth fixing for the old Qt version. The problem is that you need to convert the items to string explicitly. I think Array.prototype.join() should do that; it is probably a bug in Qt 5.

You can convert the items to strings by calling .map(str) before the .join(...):

add(texts.map(str).join(separator));

Thank you very much. Your solution works for me. 👍
