Disclaimer: I am a Chrome developer, who formerly worked on the clipboard.

For a long time, Chrome did not allow pages on the open web to use document.execCommand('copy') or document.execCommand('cut'), and there was a fairly steady stream of requests from web developers to enable this. Eventually, Chrome did expose this gated behind a user gesture: https://chromestatus.com/feature/5223997243392000

> So instead of changing their new tab page to require a gesture like all other sites... they decided to allow any website to copy text into the clipboard. Nice.

Ownership of the clipboard features has moved around a bit, and sometimes historical context around things like the user gesture requirement are lost. Here, the NTP doesn't actually need this to work without a user gesture. The correct fix here is to fix the NTP tests to correctly simulate a user gesture, not to allow writing to the clipboard without a user gesture.

> I think copying into the clipboard needs an overhaul—even with a gesture. Don't you hate when news sites add a "- from XYZ" to your clipboard? That shouldn't be possible. I'm not sure how you'd fix this, but it should be fixed.

This is a difficult problem to fix. There are absolutely websites that abuse this. But there are also pages that do use the legacy clipboard API events in non-abusive ways (e.g. rich text editors), and blocking this outright would break legitimate uses as well.

Maybe something like a "copy as plain text" option would make sense...

That's ask I _ever_ want. I never want to copy rich text. I even have a background script that removes formatting from the clipboard every second, to make copying less frustrating.

Hide it in some hidden flag or something, but please, make plain text copying an option!

[jhugo]

Right? I think, in 25+ years of computing, I have never once wanted to paste rich text. Ever. I just want to paste the text! Yet every time, I have to either fumble for the "paste and match style" key combo, or fix things afterwards.

[yjftsjthsd-h]

FWIW, I actually have wanted that, usually when I'm copying a chunk of text and I want to keep inline hyperlinks intact. I'm not sure I want that more often than I want a plain text option that strips out all the formatting, but it does come up.

[Pxtl]

The trick is that 99% of the time I want Markdown. That is, I want hyperlinks, bullets, headers, strong, etc. to stay hyperlinks, bullets, headers, etc.

But all the other styling? The fonts, the colors, stuff like that that isn't in markdown? Nobody wants that.

[rav]

Don't most apps allow you to paste plain text with Ctrl+Shift+V nowadays? That's what I almost always use, unless I have some use for the copied rich text.

[kevincox]

Annoyingly the GitHub comment box doesn't. Incredibly frustrating to copy someones name from the GitHub webpage and paste it and it pastes as a markdown link which doesn't trigger a mention.

[lupire]

Aside from GitHub doing something dumb here, Paste without formatting belongs as a browser or OS feature, not per-website code.

[hosteur]

Great idea with such a script. Do you want to share it?

[dotancohen]

Sure, it depends on `xclip`, which you might need to install, and `perl` which you probably already have. I only run it while I'm actually copying and pasting as I don't like leaving loops running, that said, with the 1 second sleep it's really not so bad.

  #!/bin/bash
  while true ; do xclip -sel primary -o | perl -pe 'chomp if eof' | xclip -sel primary ; sleep 1 ; done

Note that this affects only the primary selection, e.g. the copy-on-highlight and paste-on-middle-click clipboard. I hardly ever use the rodent, but when I do, this is what I use it for. You could easily adapt the script to the Ctrl-C Ctrl-V clipboard.

> Hide it in some hidden flag

Google is deeply philosophically opposed to doing that. Power users are a distraction from the billions of normal users.

[dotancohen]

Then make it a regular option. My point was that _if_ it's not deemed important enough to expose a UI option for, at least let make it possible some other way.

[majou]

macOS has "paste as plaintext" instead.

[macintux]

I’ve remapped ⌘V on my work laptop to paste as plain text which works great everywhere except Outlook, which disables that in email metadata (recipients, subject).

So bloody annoying, thanks Microsoft for continuing to make my life harder than it needs to be.

[lupire]

Better than Gmail which automatically parses text on paste, and, as the cherry on top, even when it recognizes that and alerts on a failed parse (making a red chip), refuses to let you edit the text to fix it.

[lupire]

All we need is "copy without running JavaScript". Just look at what is actually rendered, and copy that. And it should be the default.

[userbinator]

Why do you call it a "user gesture" and not "consent" as it should absolutely be? Is it to reinforce the notion that users' actions are only to be taken as mere suggestions and ignored if they are contrary to your goals?

[samwillis]

"user gesture" and "consent" are two completely different things.

Currently (until this bug) it’s supposed to trace back the call stack to the event that triggered it, and only allow it if the triggering event is something like a click. That’s what’s meant by “user gesture”, the opposite of code triggering it independently of the user.

“Consent” would be a positive acceptance in a browser controlled message box asking for permission to use the clipboard.

Most people agree that for copying to the clipboard the first is all that’s needed (there isn’t really a security concern here), for pasting from the clipboard the later is always required.

[userbinator]

there isn’t really a security concern here

Ok, so there is a related vector here, but it requires the site your are on to be compromised.

I would argue the actual vector is in the terminal, it should really validate the clipboard content.

[PoignardAzur]

> Is it to reinforce the notion that users' actions are only to be taken as mere suggestions and ignored if they are contrary to your goals?

Wow, rude.

One possible answer to your question: there is no way for a browser to detect "consent", which is a subtle and nuanced concept, but user gestures have a hard and fast definition, so that's the proxy they use.

[ndriscoll]

When a site wants access to my camera or microphone, the browser detects my consent by asking me. I don't see why listening to clipboard events shouldn't be treated in the same way. Likewise with mouse and keyboard tracking events.

The number of sites that reasonably need to know when I copy/paste or need to override what happens when I do that is approximately zero. There's no reason to allow it by default for all sites.
