Feature request: Treat self-closing XML/HTML tags as <>

[ebrannin-bw]

Steps to reproduce

1. Make a new document:

   <outer>
   <inner />
   </outer>

2. Put the cursor in the middle of <inner />: /inn
3. Type ysat<middle> (not shown below) or `ysat<C-T>middle> (shown)

Expected result:

<outer>
<middle>
  <inner />
</middle>
</outer>

Observed result

<middle>
  <outer>
  <inner />
  </outer>
</middle>

Workaround

ysa<<middle> or ysa<<C-T>middle>

Background

Self-closing tags come up in HTML5, XML, React, etc.

I was just turning a React component from a flex-row into a table, and as I wrapped each element with <td> I had to switch between ysat and ysa< depending on if it was self-closing or not.

I think I agree. However, surround.vim is merely delegating to Vim's built-in at operator. You can see the same behavior if you do dat or gUat.

And I don't plan on breaking with Vim here. You could try floating your proposal to Vim itself, but I doubt it would be considered due to backwards compatibility concerns.

Makes sense, thanks!

Looks like vim has already documented this:

"<aaa/>" items are skipped. Case is ignored, also for XML where case does matter.

Sounds like what I really want is a custom text-object plugin to declare something like aT and iT (or whatever, but it seems like those aren't built-in) -- I'll update here if I find one already exists or (very eventually) figure out how to write one.

Yes, but see #355.
