amunchet/noVNCCopyPasteProxmox.user.js

Forked and updated it for German Mac Keyboard.
Added Async writing to be able to paste walls of text.

Tried many mapping variants, but mapping the whole keyboard worked best.

it worked, thank you <3

Is anyone else having a problem with carriage returns? I have a multi-line copy that is pasted into one line on Proxmox. Sometimes, the leading character of the next line is omitted, too.

@Laz2047 I would try the version above by @zakhar-kogan - it might handle carriage returns a bit better (I haven't actually tried it myself). The original version was just meant to paste in long passwords or single line items, so I didn't really consider multi-lines.

Thank you. I'll check it out.

@amunchet Just came here to say I love you for making this script. It's such a massive quality of life improvement!

used this in console to paste ssh key using right mouse click.

            $("canvas").on("mousedown", (e) => {

                    navigator.clipboard.readText().then(text => {
                        sendString(text);
                    });
                }

The canvas finding logic is broken, use this for sendString() if you're using novnc and it'll work:

function sendString(text) {

        var el = document.querySelector("#noVNC_container canvas")
        text.split("").forEach(x=>{
            setTimeout(()=>{
                 var needs_shift = x.match(/[A-Z!@#$%^&*()_+{}:\"<>?~|]/)
                 let evt
                 if (needs_shift) {

                     evt = new KeyboardEvent("keydown", {keyCode: 16})
                     el.dispatchEvent(evt)
                     evt = new KeyboardEvent("keydown", {key: x, shiftKey: true})
                     el.dispatchEvent(evt)
                     evt = new KeyboardEvent("keyup", {keyCode: 16})
                     el.dispatchEvent(evt)

                 }else{
                     evt = new KeyboardEvent("keydown", {key: x})
                }
                el.dispatchEvent(evt)
            }, 100)
        })

    }
