Fontification for the inner bloc of two nested bloc

Fontification for the inner bloc of two nested bloc

[Pierre-Andre Cornillon]

Hi,

I have a question about fontification of inner src bloc.

I have two nested blocks: one special (outer bloc) and one src (inner
bloc) like this
#+begin_bloc20171001122500 
#+begin_src R :results value :session :exports both
  blip <- runif(2)
  test <- rnorm(2)
#+end_src
#+end_bloc20171001122500
and I want to have the native fontification property for the inner one.

I have already (setq org-src-fontify-natively t) in my .emacs and it
works like a charm for src blocks alone (not nested) but for nested
ones it breaks.

Is nested blocks are allowed and if so, is that possible to have that
fontification property ?

Thanks,
Pierre-Andre

Dear org-mode users/gurus


I have a question about fontification of inner src bloc. I have already
submitted this question to the list a few days ago but it did not appear
(and I suspect my mail account to be blacklisted) So I apologize first if
this question is submitted another time to the list...

I have two nested blocks: one special (outer bloc) and one src (inner
bloc) like this
#+begin_bloc20171001122500
#+begin_src R :results value :session :exports both
  blip <- runif(2)
  test <- rnorm(2)
#+end_src
#+end_bloc20171001122500
and I want to have the native fontification property for the inner one.

I have already (setq org-src-fontify-natively t) in my .emacs and it
works like a charm for src blocks alone (not nested) but for nested
ones it breaks.

Is nested blocks are allowed and if so, is that possible to have that
fontification property ?

Nested blocks are allowed, but the fontification system has a few
shortcomings, including this one. Ultimately, this part of Org needs to
be rewritten using the parser.

Anyway The bug probably lies in `org-fontify-meta-lines-and-blocks-1'.
Do you want to investigate?

what is "the parser" exactly ?

I agree that the regular search expression in the
org-fontify-meta-lines-and-blocks-1 seems to match only one level of
src block. I am not an elisp programmer but splitting
the function in two part will allow to make it recursive (and thus to
cope with several level of nested src block) ? Well it's pure
speculation without testing...

It is "org-element.el".

It probably would. But then, there is `font-lock-multiline', which
prevents further fontification.
