unable to paste text nor latex

unable to paste text nor latex

for example here: https://codepen.io/yakovyarmo/pen/gOmVpPR try to paste something

using chrome Version 91.0.4472.114 (Official Build) (64-bit)

[arnog]

Seems to work for me. Could you provide more details? What are you trying to paste?

[yakovyarmo]

Any thing. Tried latex and regular text. It only show "v". It seems that the paste event is not being triggered

[stefnotch]

@yakovyarmo Which operating system? Which language? Which keyboard layout?

[arnog]

Are you using command + V or control + V? What is your operating system? What happens if you select the Paste command from the Edit menu instead of the keyboard shortcut?

[yakovyarmo]

I'm using English layout on windows 10.

The paste command doesn't appear when I right click on the math live input.

Here is an example with a regular input:

[stefnotch]

@yakovyarmo That seems odd, I can't reproduce this. Could you try windows+v and try pasting something from the clipboard? This should work since you're on Windows.

Also, could you put this into your codepen, then hit ctrl+v and check the console?

document.addEventListener("keydown", (ev) => {
  console.log(ev.key, ev.code, ev.ctrlKey, ev.shiftKey, ev.altKey, ev.isComposing);
});

[yakovyarmo]

Here is the result of the input:

And here is the console:

[stefnotch]

That looks odd. Do you know if any software or hardware could be messing around with the keyboard/input?

At the beginning, it looks like the v key has been pressed while the control key has been pressed. After that, there are a few keyboard events with a missing code, which shouldn't happen according to MDN.

From the meta key, I'm assuming that you have some special keyboard (such as the apple keyboard)?

I don't really know what could be causing that, maybe arnog has an idea.

[yakovyarmo]

I tried it on a different computer and the same result.

[yakovyarmo]

Do you need more info from me?

[arnog]

Let's try a few more things:

• can you type regular text in the mathfield? What happens if you type "x"?
• do other commands work? What happens if you type "ctrl+A"?
• can you use arrow keys to navigate in the mathfield?
• what happens if you press shift+left arrow key?
• what about ctrl+left arrow key?

[yakovyarmo]

All of these are working, I also wrote custom key binding which did work. I did notice that the (paste event)[https://developer.mozilla.org/en-US/docs/Web/API/Element/paste_event] doesn't get fired.

Just to clarify, does the MDN demo work? Or does the paste event also not get fired there?

If it's the latter, then I'd wonder if the issue could be caused by:

• Using the same keyboard on both machines (to test: use the on-screen keyboard)
• Using the same Chrome profile on both machines (to test: start Chrome in incognito)
• Some browser setting (to test: try it with Microsoft Edge)

[arnog]

And can you clarify: when you type ctrl+v, what appears in the mathfield: "v" (which you mention earlier) or "Controlv" (which shows up in a screenshot) or something else?

[yakovyarmo]

I tried also with firefox and edge, same result. I tried different computers, same result. Just to clarify about the paste event, the MDN demo does work. I debugged mathlive and put breakpoint on the paste event and saw that it was never called while the other events (keyup, keydown etc') did.

[arnog]

The paste event is triggered by the browser, so if it's not firing, something must be preventing it... I don't know why the MDN example would work, though. You tried earlier to paste using the contextual menu. But there is also an Edit menu in the menu bar at the top of the window. This menu should have a Paste command. Is the Paste command enabled? What happens when you select this command with your mouse?

[yakovyarmo]

It is greyed out.

[stefnotch]

So, the following is greyed out for you?

In that case, I'd almost suspect some piece of software that is installed on both machines. Even though that'd be rather strange. If you do want to investigate that avenue further, you could try starting Windows in safe mode and report back.

It does work with version 0.59.0. So can we inspect what changed in that version?

[arnog]

Sure. There are 516 commits between 0.59 and the current version to go through, so that might take a while. And without a reproducible case, that's still going to be difficult to figure out a fix.

[stefnotch]

It does work with version 0.59.0. So can we inspect what changed in that version?

Just to clarify again:

• It worked in version 0.59.0
• It does not work in the latest version, which is 0.69.4

Does it work in any of the versions inbetween? Which version broke it on your system? Which version still works on your system?

Also, feel free to go into the details, every bit of information helps! Especially when trying to hunt down a non-reproducible bug.

[yakovyarmo]

It stopped working at version 0.60.0

Does it work in any of the versions inbetween https://www.npmjs.com/package/mathlive?activeTab=versions? Which version broke it on your system? Which version still works on your system?

Okay, that narrows the range down a fair bit. It's still a lot to go through. https://github.com/arnog/mathlive/compare/v0.59.0...v0.60.1 https://github.com/arnog/mathlive/blob/master/CHANGELOG.md#0600-2021-04-12

If you want to test it locally, you could try checking out the v0.59.0 commit, building mathlive from source and testing it. And then adding commits until pasting breaks.

I'm sorry for not being able to help more, usually I'd do the 'bisecting' myself, but I still haven't figured out how to reproduce this issue. (I'm on a Windows 10 Home machine, version 20H2, have tried out a number of different keyboard layouts and keyboards, different browsers. No dice.)

[yakovyarmo]

Where can I find the commit for: "

• Fixed issues with copy/paste. Copying from a text zone will copy the text (and not a latex representation of it). Copy from a Latex zone now works."

The Clipboard handling has been significantly rewritten and should now work in a wider set of environments.
