Hi Ihor,

Don’t worry, that’s just a snippet. The full logic is as follows
┌────
│ (min limit (or (save-excursion (and (search-forward "\n" limit t 2) (point)))
│ (point-max)))
└────
>> [use org-element]
Ah right. We now also have the new thread about using org-element. I think that
sounds like a great change overall, but am still keen for this patch to go
through for the moment — just as a stop gap till org-element exposes all the
necessary information and there are some nice examples of using it for
fontification.
I’ve attached the latest version of the patch. At this point I consider it
fairly well-reviewed, so I’ll push it tomorrow if I don’t hear of any
last-minute issues.
All the best,
Timothy

Subject: [PATCH] org-src: Implement native inline src fontification
* lisp/org-src.el (org-fontify-inline-src-blocks,
org-fontify-inline-src-blocks-1): Create a function to search the buffer
up to a limit for inline src blocks. Light fontification is applied to
matched inline src blocks. When `org-src-fontify-natively' is
set, `org-src-font-lock-fontify-block' is applied to the content.
* lisp/org.el (org-set-font-lock-defaults): Add
`org-fontify-inline-src-blocks' to `org-font-lock-extra-keywords', which
is locally bound inside `org-set-font-lock-defaults'.
* lisp/org-faces.el: Introduce a new face `org-inline-src-block' which
inherits from `org-block' by default.
