Feature Request: Make formatting actions toggle instead of only adding

[soryy708]

Is your feature request related to a problem? Please describe.
Currently, every time you do a formatting action (use a hotkey, or press a button), it adds a new tag.
This is not intuitive, because users are used to UX like in MS-Word, where for example pressing Bold on already bold text makes it not bold.

Describe the solution you'd like
Make formatting actions toggle instead of only adding

How I'm imagining this could work:

• If the beginning of the selected text is on or immediately after a [starting] tag, delete it and create a new [starting] tag at the end of the selected text

• Else, if the ending of the selected text is on or immediately before an [/ending] tag, delete it and create a new [/ending] tag at the beginning of the selected text

• Else, create an [/ending] tag at the beginning and a [starting] tag at the end of the selected text

• If the above results in an [empty][/empty] set of tags, delete them

@Dibasic That would potentially generate invalid XML / HTML.

Consider the following:

[u]Hello [b]world[/b][/u]

Where the selected text is:

[u]Hello [b]wo

We will end up with

Hello [b]wo[u]rld[/b][/u]

How I'm imagining this could work:

• If either end of selection is child of the tag we're adding, delete that parent.
• Else, wrap selection in that tag

This ensures valid XML/HTML, but acts a little strange. If you have any amount of characters selected in a bold line, and you perform the bold formatting action, the entire line will stop being bold.

Tricky. I don't know how this should behave if the user selects something that spans several tags, spans more closing tags than opening tags, etc.

Overall tricky feature. Perhaps look in to how other WYSIWYG editors accomplish this?
