[bug] "Invalid face" when exporting code block to HTML

[bug] "Invalid face" when exporting code block to HTML

[Sebastien Vauban]

Hello,

Not a good day for me, today...

* Summary

Quite "simple": the following block generates an "Invalid face" error when
exported to HTML.

#+begin_src sh
svn checkout http://svn/trunk/dev/ mydev
#+end_src

This worked yesterday. Does it ring a bell to someone? Could some recent
commit be responsible of this?

Can't reproduce it either with a slightly earlier version of org (.19)
or latest (.44 - note that I'm ahead of origin/master by 3 commits).

Try evaluating this expression which is the one that gave you the error:

(htmlize-face-size 'default)

I get 113 in my setup, so this looks like an htmlize error. I don't
understand where the nil face (which is indeed invalid) comes from.

Also htmlize-face-size wraps the face-attribute call inside an
(ignore-errors ...)  form, so it should *not* blow up. Are you using
some old outdated htmlize code by any chance?

Indeed:

#+begin_src emacs-lisp
Debugger entered--Lisp error: (void-function htmlize-face-size)
  (htmlize-face-size (quote default))
  eval((htmlize-face-size (quote default)) nil)

I don't understand, as I did not do any Emacs changes lately in that area.

Library is file `~/Downloads/emacs/site-lisp/htmlize.el', where I have all
independent package files downloaded from the Web.

Wait... That should be `~/src/org-mode/contrib/lisp/htmlize.el', right?
                              ^^^^^^^^^^^^^^^^
So, I have 2 `htmlize' files, and the Org-compliant one is only located in the
second best place.

I have -- still! -- absolutely no idea why the original `htmlize' file worked
for me so far, and why it suddenly stopped working yesterday (I did no change
of load-paths, neither did I save that file there... it must be a very old
reminiscence).

I still have found out that -- with the original (non-Org) `htmlize' file --,
I need to have a declaration like this:

#+begin_src emacs-lisp
       (default ((t (nil))))
#+end_src

in my color theme.

With the Org flavor of `htmlize', that line is not needed.

For sure, yesterday, I played with that line, *after* things had gone wrong,
as I wondered whether such a line, with `nil', was good or not to have.

Now, there are 2 ways to solve my problem for sure:

- putting the original `htmlize' after the Org paths,
- removing it.

The first solution does not feel natural to me: I need having the proper
load-paths set up for Org in my stub .emacs (calling my tangled, huge file
full of Emacs customizations). It's because ~/Downloads/emacs/site-lisp/ is
added to the load-path in that huge .emacs file that it's finally in front of
Org git directories, as the append is done upfront -- no prepend.

Now, I really don't need to have conflicting versions of `htmlize', so I
simply deleted that file -- whose I ignored the existence up to now --, and
all is so far so good.

Thanks (a lot) for putting me right on track!

Best regards,
  Seb
