Feature request: Add QR-code generator

[oneofthehorses]

Hello!

It would be awesome to see function for fast generation of QR-codes from clipboard :) also QR reader to clipboard too*!

And (look into further) possibility to exchange public keys first, to establish secure communication channel (if works in public space, not home) so no man in the middle can catch real clipboard information

Thanks for your work!!

This is supported through commands. The following command (uses qrcode utility - must be installed) creates a new item with the QR code from currently selected text item (see README.md for details on how to add the command):

[Command]
Command="
    copyq:
    const result = execute('qrcode', '--factory=pil', null, input());
    if (!result) {
        popup('Failed to run qrcode');
        abort();
    }
    if (result.exit_code != 0) {
        popup('Failed to run qrcode', result.stderr);
        abort();
    }
    write('image/png', result.stdout);"
Icon=\xf029
InMenu=true
Input=text/plain
Name=QR Code

CopyQ must be able to find the utility, i.e. it must be reachable from a directory listed in PATH environment variable.
