Proposal

Please re-state the problem that we are trying to solve in this issue.

Pasting long text in description not scrolled to bottom

What is the root cause of that problem?

In the private notes page, we use useHtmlPaste on the input ref, which handles moving the cursor when pasting from clipboard. however we don't do that in the description page

What changes do you think we should make in order to solve the problem?

To ensure consistency, we should call the useHtmlPaste(reportDescriptionInputRef); inside the room and task description pages as well.

We can also do that in other places if needed.

alternatively

For a global solution, we can use the useHtmlPaste inside the TextInput and we should add a prop disableUseHtmlPaste that would disable the hook call ... this would be useful for the compose where we pass the onPaste function to the hook, this prop can be used in other cases as well.

Another solution

OR more specifically since the issue occurs when the isMarkdownEnabled is enabled then we can enable the useHtmlPaste hook when the markdown is enabled.

Proposal

Please re-state the problem that we are trying to solve in this issue.

Pasting long text in description not placing cursor at end of text

What is the root cause of that problem?

Cursor positon is not corrected while pasting text similar to Composer text field.
The text input is neither subscribed to useHtmlPaste hook nor having a similar logic for correction of cursor while pasting from clipboard.

What changes do you think we should make in order to solve the problem?

useHtmlPaste hook to be used in description text field similar to composer and notes text fields.
However, if the approach is an overkill in case certain characters are not permitted in description, we may reuse the logic from useHtmlPaste to address the issue here.

What alternative solutions did you explore? (Optional)

N.A.

@mollfpr can you review @kpadmanabhan proposal above and the issues I linked above too?
#45885 (comment)

[abzokhattab]

this proposal is the same as mine ... can u please let me know your opinion about my proposal?

[mollfpr]

I agree that the @kpadmanabhan solution is the same as the @abzokhattab proposal. It seems using useHtmlPaste is fixing the issue, but can we seek a universal solution so it can fix the issue in another place?

[abzokhattab]

Updated Proposal: added an alternative solution

[kpadmanabhan]

@abzokhattab : didnt notice your proposal earlier. sorry for that.

@mollfpr : according to me useHtmlPaste itself is a universal solution as it is the central handling for all paste actions for the control passed in. We can add this by default to any text input, unless it is unsubscribed explicitly.

@mallenexpensify @mollfpr this issue was created 2 weeks ago. Are we close to approving a proposal? If not, what's blocking us from getting this issue assigned? Don't hesitate to create a thread in #expensify-open-source to align faster in real time. Thanks!

[melvin-bot]

@mallenexpensify, @mollfpr Huh... This is 4 days overdue. Who can take care of this?

[melvin-bot]

📣 It's been a week! Do we have any satisfactory proposals yet? Do we need to adjust the bounty for this issue? 💸

Hello, I decided to investigate this issue more inside the library since I have more capacity. To fix this issue and overall scrolling into view logic, we have to make some bigger logic changes inside the library.

First of all, we don't need to scrollIntoView on every input change or event. We can do it only on the actions that were totally replaced by our custom implementation, like: onPaste and onFocus and value prop changes. The rest of the actions can use the default browser's scroll logic. Thanks to that, Live Markdown Input works and feels more like normal RN TextInput.

After that, we can update our scrollIntoView function, so whenever the cursor isn't visible inside the input window, it scrolls to the position of the cursor range. Something like this:

 const selection = window.getSelection();
    if (selection && selection.rangeCount > 0) {
      const range = selection.getRangeAt(0);
      const caretRect = range.getBoundingClientRect();
      const targetRect = target.getBoundingClientRect();

      // In case the caret is below the visible input area, scroll to the cursor position
      if (caretRect.top + caretRect.height > targetRect.top + targetRect.height) {
        targetElement.scrollTop = caretRect.top + caretRect.height - targetRect.top - targetRect.height + target.scrollTop;
      }
    }

I will come back to you with the PR today
