Suggestion: Run Check addition for 'do nothing' tags

phossler · 02-07-2014, 07:13 PM

It would seem (to me at least) that if I have no text selected, then ...

a) I would not want to insert 'do nothing' tags for bold, italic, color, underline, etc.

So my first thought was to suggest ignoring the [B] or [I] etc.

However, then I realized that ...

b) I might want the tags because I want to insert text between them

So finally I thought possibly

c) a [Run Check] question and cleanup of empty tag pairs

Code:

  <h1>test<b><i><u><strike><span style="color: rgb(255, 0, 0)"></span></strike></u></i></b></h1>

Be a little complicated I guess since (as in the example) the is empty making the <strike> empty making the empty making the empty and finally making the empty

I'm not sure, but white space would not count since who wants a bold space

Code:

  <h1>test</h1>

There is no way to know that a tag is empty, since an empty tag could be styled with css to have a fixed width/height or border or background color.

That's more advanced than I was thinking (maybe I was anyway).

It was just that I was using the new editor window dropdown to select [H1], etc. and then tried the [B] and other buttons.

My use of 'empty' a little simplistic: if there was 0 length text selected (i.e. just the insertion point) then I called it empty since I didn't see any value in at least the 'standard' format tags such as

When there's a capability to store F&R strings, I can come up with some RegEx (or at least I think I can) to handle things like that

technically right, but practically speaking usually not.

so is there a way to remove empty tags?

It doesn't really make any difference in what is displayed and they can be searched and replaced.
