Dears,

Org is awesome and now I use it as my blogging tool, everything is
perfect except the source code highlighting. Org uses htmlize.el to
highlight source code, it's fine, but when I use another theme or on a
different machine, the generated html(contains source code block) will
change due to Emacs theme change. As I use git to manage my generated
html files, so when publishing after a theme change, those html files
contain source code will change and thus I need to *git commit* a lot
of files without actual useful content change!

So now I want to use google prettify.js to highlight my source code,
but I cannot disable htmlize.el during exporting, I googled and
someone said removing htmlize.el will achieve this, but I don't think
it is a good idea.

Any ideas?

Thanks,
Kelvin

I'd try to set `org-html-htmlize-output-type' to nil but I didn't
test.  If it does not work, this is a bug.

Hi Bastien,

Thanks for your reply, I have tried this approach, but it reports
"error: (void function nil)".
Per the definition in `ox-html.el', it must be either 'inline-css or 'css.

After some research, now I use the following workaround:

(flet ((org-html-fontify-code
        (code lang) (when code (org-html-encode-plain-text code))))
  ;; code here
  ;; e.g. (insert (org-export-as 'html nil nil t nil))
)

Redefine the function `org-html-fontify-code' will help, but I think
this workaround is a little ugly. So, I hope this feature can be
disabled gracefully, like set `org-html-htmlize-output-type' to nil.

But it's an excellent idea. I have a patch to ox-html which will allow 
ox-htmlize-output type to be set to `nil', to explicitly return plain 
text.

I will push it to master tonight when i get out from behind the 
firewall...
