Inline src blocks cannot update their results --- causing some of us
heaadaches [1].
These patches fix that by placing the result of an inline src block in an
export snippet with a faux :back-end called 'babel'.
So C-c C-c with point on src_R{1+2} will insert `@@babel:3@@'. Updating
the contents of the inline src block and retyping C-c C-c will update the
snippet. On export, these snippets are rendered using the verbatim
transcoder, e.g. \texttt{3} for latex backends.
Support for most backends is provided.
org-babel-execute-buffer will also update such snippets.
Please try these patches out.
Remember to recompile the files that these patches modify or you will get
wrong results when you restart emacs.
HTH,
Chuck

Subject: [PATCH 5/5] lisp/ob-core.el: Enable removable inline src results
* lisp/ob-core.al (org-babel-inline-result-wrap,
org-babel-insert-result, org-babel-delete-babel-snippet): Inline src
blocks results are export-snippets with a faux `:back-end' of `babel'.
(org-babel-inline-result-wrap): Now `@@babel:%s@@'.
(org-babel-delete-babel-snippet): Remove a babel export-snippet.
(org-babel-insert-result): Remove a babel export snippet.
The treatment of inline src block results as verbatim,
e.g. `=result=', makes finding and removing them programatically
tricky and risky. By wrapping them as `@@babel:result@@' they can
be found and removed.
