First the basics... minor details:

Now, the logic:

  • dir == editor.lang.dir: editor.lang is exclusively related to the editor UI language. It has nothing to do with the contents language. In that specific case, I think you were talking about the contentsLangDirection setting.
  • In any case, checking contentsLangDirection may not be enough, because the blocks may be inside a container (a div or a td) with direction different from contentsLangDirection.

Basically what we need is a way to be sure that the direction is always applied (not removed nor switched) for subsequent blocks if their current direction differs from the direction of the first block. For that, an additional parameter could be passed to the switchDir function.

I've just found a tc that fails with this patch:

  1. Load the following:
<p dir="ltr">
	Line 1</p>
<p dir="ltr">
	Line 2</p>
<p dir="ltr">
	Para 3</p>
  1. CTRL+A to select all.
  2. Click the LTR button to remove the "dir" attribute.

Expected: The attribute is removed from all paragraphs.

After patch: The attribute is removed from the first paragraph only.

The bidi command actually have the same operation model with justify, where the command state is decided by the first block's style and in return gives the correct state to each block iteration, we could simply follow the logics how justify command dealt with this instead of introducing this additional parameter:

var apply =
	( this.state == CKEDITOR.TRISTATE_OFF ) &&
	( !useComputedState || ( getAlignment( block, true ) != this.value ) );

Nice done, as the final mile, would you mind simplify the following lines, to make it perform a little bit better, if you agree, we save a couple of style manipulation by placing them into a separate 'else'.

element.removeStyle( 'direction' );
element.removeAttribute( 'dir' );

if ( state == CKEDITOR.TRISTATE_OFF && element.getComputedStyle( 'direction' ).toLowerCase() != dir )
	element.setAttribute( 'dir', dir );

Do you mean something like this:

element.removeStyle( 'direction' );		

if ( state == CKEDITOR.TRISTATE_OFF && element.getComputedStyle( 'direction' ).toLowerCase() != dir )
	element.setAttribute( 'dir', dir );
else
	element.removeAttribute( 'dir' );

It won't work, beacuse element.removeAttribute method changes ComputedStyle of the element, so it must be called before 'if' clause. Otherwise, you have to change the other logic in attached patch.

But look here, in justify plugin, it's more-less the same:

block.removeAttribute( 'align' );
block.removeStyle( 'text-align' );

var apply =
	( this.state == CKEDITOR.TRISTATE_OFF ) &&
	( !useComputedState || ( getAlignment( block, true ) != this.value ) );

if ( apply )
	block.setStyle( 'text-align', this.value );

and it's used only 'if' clause, without 'else'.

You're right, it's enough to keep 6237_4.patch
