Re: [O] [BUG] src_blocks - :wrap blocks not being overwritten

[Carlos García]

Hi Chuck,

Thanks for looking into this. How difficult/desirable would it be to create another block such as "wrap-block" for those blocks created with ":wrap"?

That way, the needed change would be rather elegant:

:line 2478 of ob-core.el:

| ;; Possible results types.

|      '(drawer example-block export-block fixed-width item

|       plain-list src-block table wrap-block)

What would the repercussions be if `special-block' is added to the list?

Regards,

Carlos

Confirmed. 

The issue is that the #+BEGIN/END_results is a `special-block', which is not recognized in `org-babel-result-end' as a result type.

I think the fix is to add it.

If the intention is to NOT recognize special-blocks as results, then the empty :wrap needs to have some other effect, like enclosing the result in a drawer.

HTH,

Chuck
