Re: [O] How to activate pre.src in org-babel html output? Can only get class=example
Hi Eric
My guess is that during export you get a message along the lines of
htmlize is required for export. Try explicitly loading htmlize.el
(in the contrib/lisp directory of org) and then re-exporting ...
You're spot on - importing htmlize.el did the trick. However, before importing
it, there weren't any error messages about it being missing. All would work
happily, but the source block didn't have the additional src and src-python tags.
To me, this seems like a bug or at least not ideal, as the src tag and the
src-language tag are related to the HTML export of #+begin_src block, not on
*how* the HTML is styled (i.e. by the user or htmlize).
For those searching the mailing list later:
; For pretty-printed formatted source code on HTML export,
; load htmlize.el in init.el or the emacs config file
(load-file ~/.emacs.d/orgmode/contrib/lisp/htmlize.el)
I've got the orgmode source in the .emacs.d directory so I can pull updates
using git, otherwise look for contrib/lisp/htmlize.el in the main Emacs directory.
With htmlize.el loaded, exporting:
,
| #+begin_src python :results output :exports both
| print Pi = , 355/113.0
| #+end_src python
`
Results in the src block having the src and src-python CSS tags:
,
|pre class=src src-python
|span style=color: #a020f0;print/span
|span style=color: #8b2252;Pi =/span, 355/113.0
|/pre
|
|
|pre class=example
| Pi = 3.14159292035
|/pre
`
with an automatically added little Python flag box on the Python src block.
Some custom CSS can be used to make the src and output a little more distinct. A
simple way is it place these lines at the top of the file:
#+style:style pre.src {background-color: #DD;}/style
#+style:style .example {background-color: #CC;}/style
However, you have to be consistent about using #+begin_src blocks rather than
just a colon or using begin_example at the beginning of lines for src fragments
that don't output anything, otherwise Python src they'll come out with the
output colouring. The keyboard shortcut ( s tab) for getting a
#+begin_src---#+end_src block is handy here.
Although the example above relates to #+begin_src python blocks, the fix should
work with other languages.
Cheers and thanks
Giovanni

Re: [O] How to activate pre.src in org-babel html output? Can only get class=example
Hi Giovanni, When I export the following code block , | #+begin_src emacs-lisp :exports both | :foo | #+end_src ` it generates the following HTML. , | pre class=src src-emacs-lispspan style=color: #d0d0ff;:foo/span | /pre | | | pre class=example | :foo | /pre ` My guess is that during export you get a message along the lines of htmlize is required for export. Try explicitly loading htmlize.el (in the contrib/lisp directory of org) and then re-exporting and you should get the desired output.
