[-- Attachment #1.1: Type: text/plain, Size: 1883 bytes --]

Had no experience with the :DIR: property or writing unit tests for Org,
but I think I've got both covered now.
The ID creation prompting now only happens if there is no result from
org-attach-dir, which should address the :DIR: case.

Let me know if there's anything about those tests that I should modify.

Thanks,
  -ryan

Subject: [PATCH] ob-core.el/babel: Special handling for attachment links in
 src block

* ob-core.el (org-babel-merge-params): Specifying the symbol 'attach`
or string "'attach" as the value of the `:dir' header now functions as
":dir (org-attach-dir nil t) :mkdirp t"
(org-babel-result-to-file): Optional `TYPE' argument accepts symbol
'attachment` to fixup up paths under `(org-attach-dir)' and use the
link type "attachment:" when that is detected.
(org-babel-insert-result): Pass symbol `attachment' as `TYPE' to
`org-babel-result-to-file'
* org-attach.el (org-attach-dir): Added autoload header to simplify
dependencies necessary to support this feature (called in
`org-babel-merge-params').
* test-ob.el (test-ob-core/dir-attach): Added unit test for new attach
feature
