Q: org-publish-project-alist and :exclude

Q: org-publish-project-alist and :exclude

[David Masterson]

In the Org Mode manual section 14.1.3, it says that ":exclude" takes a
regular expression of filenames to exclude from publishing but it
doesn't really explain what the regular expression format is (I assume
Elisp regex).  I have two Org files that I want to exclude:

* calendar-beorg.org
* init.org

So I have this form:

  :exclude "\(init\|calendar-beorg\).org"

but that doesn't seem to work as I get an ignorable error in processing
calendar-beorg.org (a known Beorg issue).

Is my regex wrong?

Yes. You got to escape the \ inside string.
I recommend using `rx' instead to avoid the backslash hell.

Thanks, I didn't know about `rx'.

Hmm.  Couldn't get rx (or rx-to-string) to work for me.  Kept getting an
error that a stringp was expected for the argument to :exclude. I tried
variations on:

  :exclude (rx-to-string (seq (or "init" "calendar-beorg") ".org"))

Reverted to using a simple regex as above with proper escapes.  Can I
suggest making the complex example in 14.3.2 of the Org Manual use a
better example regex (in rx form?) as a hint to what :exclude can do?

When you have '(:foo bar :baz eet), nothing inside is evaluated because
of the quote. To evaluate expressions selectively, use backquote:

`(:foo bar:baz ,(concat "foo" "bar"))

I always had trouble with '"` in hacking Elisp.  I should've studied the
language more 40 years ago... :(

I spoke too soon -- I'm still getting the same error about expecting a
string.  You mentioned '`' above, but use ',' in your manual diff.  I
tried both (along with rx-to-string).
