nested blocks in org

nested blocks in org

can you point me in the right direction of getting org mode to recognize
nested blocks, like code highlighting for src blocks that are within
another special block? and getting org-element-map to iterate through both
a parent and its child blocks all the same?
could modifying `org-block-regexp` to be a recursive regex be of help?

May you please give an example of what you have in mind?

... which is just a bug in the Org fontification code.
If you try M-: (org-element-at-point) <RET>, you will see that Org does
recognize the code block.

So ...

Org already recognizes nested blocks using Org element parser. See
https://orgmode.org/worg/dev/org-element-api.html

See https://list.orgmode.org/87ee7c9quk.fsf@localhost/
This is something we are working in.
To get parser-aware fontification locally, you can use a function
MATCHER (as in font-lock-keywords docstring) and invoke
`org-element-at-point' there to check context.

May you elaborate? `org-element-map' iterates through everything,
including nested parent and child blocks. What did you try?

Sorry, but it is hard to see how this is related to `org-element-map'.

Re: nested blocks in org

[mahmood sheikh]

with the given minimal example:
```
#+begin_parent
#+begin_child
#+end_child
#+end_parent
```
the code
```lisp
(org-block-map (lambda () (message "elem: %s" (org-element-at-point))))
```
goes through only the parent element and doesnt run the lambda on the
child block
the docstring of org-block-map says it iterates through src blocks but
it also goes through special blocks, albeit not nested ones, i
might've confused it for org-element-map as im not sure about the
later functions behavior.

This is a bug in `org-block-map'.
