Alignment Issue : When whole text is selected it always shows left aligned about plate HOT 10 CLOSED

Hey @zbeyens pls look into the PR that i opened regarding above bug

from plate.

I think this issue is caused by isCollapsed function which is using range.isCollapsed from slate

  isCollapsed(range: Range): boolean {
    const { anchor, focus } = range
    return Point.equals(anchor, focus)
  },

the problem is arising because our anchor and focus are equal but we have different offsets which is making isCollapsed false

from plate.

Yes, for the sake of reducing the complexity of the work, we haven't considered the expanded situation temporarily.

@felixfeng33 can i create a PR for this fix by adding below function

const isCollapsedInternalFunction = (range?: Range | null) => {

  // Early return for null or undefined range
  if (!range ||!range.anchor ||!range.focus) {
    return false;
  }

  // Destructure the anchor and focus properties for easier access
  const { anchor, focus } = range;
  const { anchor, focus } = range;

  // Check if both anchor and focus exist and have the same path coordinates
  if (anchor && focus && anchor.path.length > 0 && focus.path.length > 0) {
    return anchor.path[0] === focus.path[0] && anchor.path[1] === focus.path[1];
  }
};

I think you can check the parent node props in the else statement.

In your solution could I selection cross block?

from plate.

yes you can do cross selection in blocks as alignment is always block level

I have a question if a selection has first block center next block left what should be the overall alignment to be shown on top in mostly cases we show first block selection details can we do the same here

from plate.

It's better the overall alignment is none.

from plate.

I think we had better do some thing here since it's have more readability·
if (isCollapsed(editor.selection)) {
}else {
do some check here
}

from plate.

We should check the value of all selected blocks using getNodeEntries, and return true only if every block has the same value. One different value makes it false (like marks).
