[babel] How to fontify blocks other than begin_src?

[babel] How to fontify blocks other than begin_src?

[-- Attachment #1.1: Type: text/plain, Size: 719 bytes --]

I would like blocks like begin_html/end_html to be fontified just like
begin_src blocks are.
I would also like to define my own source blocks for clojure (basically a
shorthand) and also have them highlighted. Heres what i have to turn on
fontifying and define a block.

(setq org-src-fontify-natively t)
;; define #+clj as start of clojure code block and #+end as end of block
(add-to-list 'org-edit-src-region-extra
   '("^[ \t]*#\\+clj.*\n" "\n[ \t]*#\\+end" "clojure"))

Ive also noticed that the code block (#+clj ... #+end) doesnt fold -
however, if i define the block as begin_clj and end_clj it will fold, so im
guessing org assumes a certain block format for folding code.

Any way to do the above two things?

Hi Seth,

The easiest way to fontify embedded html is most likely to wrap the html
in "#+begin_src html" code blocks.

As for defining your own clojure blocks that sounds like a risky
proposition to me.  All of the code block evaluation functions are built
to use standard org-mode syntax for code blocks, e.g. "#+begin_src lang".

That said you can easily use clj as an alias for clojure in your code
blocks, use the following elisp code to add this alias to
org-src-lang-modes

#+begin_src emacs-lisp
  (add-to-list 'org-src-lang-modes '("clj" . clojure))
#+end_src

Once that is done you will notice clj blocks like the one below are
fontified.  Also, after pulling the latest version of Org-mode (I just
made a small change to make this possible), it is also possible to
evaluate "#+begin_src clj" blocks as though they were regular "clojure"
blocks.

#+begin_src clj
  (map (partial + 1) (range 20))
#+end_src

Hope this helps -- Eric

Thanks, it does. Yep, i looked at the code, and everything was  based on
begin_src - so i think i will keep it at that!

For those who are interested in changing the appearance of Org elements
for aesthetic reasons, there is Nicolas Girard's org-icons project,

https://github.com/ngirard/org-icons

which needs further work (i.e. needs to be adopted by someone) if it is
to become generally useful. It aims to provide facilities for altering
the display of arbitrary org elements, including the option of
displaying icons in place of the text. In the branch named 'dan' I
started to add support for begin_src blocks.

To address the other side of org elements (i.e. the typing/insertion
rather than the display) I find yasnippets [1] indispensable.  A
collection of Org-mode snippets are available at [2].
