Well, the huge flaw will never be obvious with such solutions... because the flaw is precisely this: it hides huge flaws. (Do not bother parsing the above, I'm not sure myself.) FWIW here is my gut reaction: I'm not a fan (euphemism) of escaping here, I feel like it adds little value while bumping complexity too much. But exploring it might be worth it, if someone wants to try! -- Bastien

I don't see how to do it cleanly without some form of escaping (to allow anything to be quoted), which goes against the "verbatim" idea. A suggestion could be to allow any text inside the markers, except for the marker itself which would need to be escaped. Escaping could take the form of doubling the marker: ~"foo bar"~ --> "foo bar" ~"foo ~~ bar"~ --> "foo ~ bar" As I've not thought this through, I'm pretty sure someone will find a huge flaw in this suggestion.

Well, preventing users from shooting them in the foot is part of why `org-emphasis-regexp-components' is not a custom variable (it used to be, but that led to lots of confusion.) I hope we can get rid of this variable one day or another. In the meantime, copying and tweaking is the way to go... HTH, -- Bastien

Thank you, this is it. I had not understood that BORDERs were inside the MARKERs (although the help text is quite clear in that regard). Is there a nice way to customize `org-emphasis-regexp-components'? It does not seem to be exposed to `customize-variable', and copying and tweaking its default value in my configuration file feels ugly. Alan

Sorry - I need coffee. I read what you wrote and promptly forgot
all of it. So ignore most of what I wrote.
However, the part about the BORDER regexp is correct I believe: in ~'a ref~,
the ~ are the MARKERS; ' and f are the BORDER and "a re" is the BODY.

See if
http://article.gmane.org/gmane.emacs.orgmode/73036/match=org+emphasis+regexp+components
can help make some sense out of the line noise (although it was
triggered by a different question). I believe the problem here is
the BORDER regexp (the one that goes
"
,\"'"
above), not the BODY one: it forbids newlines, commas, double
and single quotes. Try deleting the single quote from it.

Thank you for the suggestion. I'm trying to make sense of it:
--8<---cut here---start->8---
org-emphasis-regexp-components is a variable defined in `org.el'.
Its value is (" ('\"{" "- .,:!?;'\")}\\" "
,\"'" "." 1)
Documentation:
Components used to build the regular expression for emphasis.
This is a list with five entries. Terminology: In an emphasis string
like " *strong word* ", we call the initial space PREMATCH, the final
space POSTMATCH, the stars MARKERS, "s" and "d" are BORDER characters
and "trong wor" is the body. The different components in this variable
specify what is allowed/forbidden in each part:
pre Chars allowed as prematch. Beginning of line will be allowed too.
post Chars allowed as postmatch. End of line will be allowed too.
border The chars *forbidden* as border characters.
body-regexp A regexp like "." to match a body character. Don't use
non-shy groups here, and don't allow newline here.
newline The maximum number of newlines allowed in an emphasis exp.
You need to reload Org or to restart Emacs after customizing this.
--8<---cut here---end--->8---
I see that "body-regexp" is "." so the problem is not from there. I also
see that "'" is forbidden as a border character, which should be fine in
my case as I'm using "~". So is the problem that "'" is both in prematch
and postmatch? But in my case I use it as a body character.
So I'm afraid I don't understand why the "'" in ~'a ref~ is not accepted
as a body character, and what I should do to make sure it is.
Thanks,
Alan
