Re: [O] [PATCH] inline src block results can be removed

[Aaron Ecay]

Hi Chuck, Hi Nicolas,

I had a response to Chuck’s earlier message that was sitting around
waiting to be finished...time marches on however.  Apologies.  I think
the following bit is the only part that’s potentially still relevant:

I see what you mean.  One option might be to do the following in
org-export-as (untested pseudocode):

(org-macro-initialize-templates)
(let (results-macro)
  (setq results-macro (assoc "results" org-macro-templates))
  (setq org-macro-templates (remove results-macro org-macro-templates))
  (org-macro-replace-all org-macro-templates)
  (org-export-execute-babel-code)
  (org-macro-replace-all (list (or results-macro
                                   (cons "results"
                                         org-default-result-macro) ;; new 
defcustom or defvar
                                   ))))

Back to the present:

This is a step back from the present situation, where a user can get
a custom format applied by default to all inline results by setting
‘org-babel-inline-result-wrap’.  I think it’s reasonable for users to
want to set off babel results in a special font (to indicate that
they are automatically generated, e.g.)  This proposal would add an
additional overhead for generating this formatting to every inline
call.

I think the method I sketched above will allow users to redefine the
results macro in the same way as any other macro (via #+MACRO), thus
allowing the possibility of user-specified special formatting.

Indeed, this seems correct.  (The “const” designation is just a hint to
users/developers – it doesn’t affect the ability of people who really
want to customize the value to setq it to something else in their init
file.)

This doesn’t mesh with the suggestion to allow the results macro to
supply formatting.
