Ok, just tried org-html-export-as-html and see it renders properly
in html:
... expression <code>(x +. y)</code> the <code>+.</code> is ...
but I feel like there's a bug in the regex, that the =code= and
~verbatim~ marker characters should be able to prevent any other
marker characters bracketed by them from causing highlighting. Not
sure if I'll have time to dig into this any time soon, but it'd be
interesting to see how markdown-mode.el handles `inline code` defined
by backquotes, as it doesn't have the issues I'm seeing with how org.el
renders inline code. For example, all the text contained within the
backquotes here: `is this *bold* ?` shows up highlighted as code,
the *bold* there looks no different. In org-mode however, the *bold*
in ~is this *bold* ?~ shows up highlighted as bold, even though
org-html-export-as-html renders it as <code>is this *bold* ?</code> .

I tried this:
(setq org-emphasis-alist
(quote
(("*" bold)
("/" italic)
("_" underline)
("=" org-verbatim verbatim)
("~" org-code verbatim))))
but for some reason I'm still seeing the exact same issues. In any
case, I don't think trying to do away with strike-through capability
is something I'd like to pursue. When viewing OCaml code in org-mode,
these also will not render properly:
in =(x *. y)= the =*.= is a function ...
in =(x /. y)= the =/.= is a function ...
highlighting this section as bold and italic respectively:
. y)= the =
Ideally I'd like to make the org-verbatim and org-code emphasis regex
more robust.
Regards,
John
