I am trying to implement a new backend based on the HTML export. I need
to do some post-processing to the source blocks that needs to be
optional. For some blocks I need to replace "[" with "\[" and for some I
don't.

I am not sure whether to use headers or switches.

So

#+begin_src java -s
  student[ 4 ]
#+end_src

would produce html with

  student\[ 4 ]

inside, while

#+begin_src java
  student[ 4 ]
#+end_src

would produce just

  student[ 4 ]


Is it possible to add new switches? And in the exporter how do I know
which switches are present on a block?

Phil

What about neither?  Maybe something along #+ATTR_XXX: instead, where
XXX is the name of your derived backend, along the lines of ATTR_HTML
and ATTR_LATEX?

Others may tell us that my suggestion is worse but I think playing
around with the babel syntax is asking for trouble...

That's a good call, I think. The latex example is very clear, so I've
got that implemented now.

Are these form of attributes specific to the source block which they
precede? Or is it possible to do any kind of inheritance with them? For
my use case, all the code blocks inside a Header One block will behave
in the same way (either with \[ escaping or without).

Not a major problem if not, I can template it if not, but useful to
know.

No idea!  Maybe Nicolas can help here as I assume this is all a function
of the parser.

No worries. Many thanks for the feedback.

Attributes apply to the block below. However, with a parse tree filter,
it is possible to find a block with some attribute and apply the same
attribute to all blocks in the same level one heading.
