Babel: Programmatically evaluate a heading and subtrees?

Babel: Programmatically evaluate a heading and subtrees?

[Nathan Neff]

[-- Attachment #1: Type: text/plain, Size: 637 bytes --]

Hello all,

I have some code like this:

* Heading 1

# code block name:FOO

** Subheading 1

# code block

** Subheading 2

# code block

I find that I often want to evaluate the code in Heading 1 and its
subheadings.

Currently, I navigate to Heading 1 and then use org-babel-execute-subtree

I see that there's a function called org-babel-goto-named-src-block, so I
think
I could write a small function to jump to FOO in Heading 1 and then run
execute subtree
and then jump back to my previous location in Emacs.

Is there a more programmatic or built-in way?  For example:
org-babel-execute-block-and-subheadings FOO

Thanks,
--Nate

Can you use noweb? In the example below, if you run the top code block
babel will run the two that follow.

A drawback is that you have to redefine variables, but it might be a
benefit, since the individual blocks could be set with test data and
the "main driver" could point to real data.
-------

#+begin_src elisp :results output :noweb yes :var data=data1
  <<fun1>>
  <<fun2>>
#+end_src

#+RESULTS:
: called fun1: some data
: called fun2

#+name: data1
some data

#+name: fun1
#+begin_src elisp :var data=data1
(princ (format "called fun1: %s" data))
#+end_src

#+name: fun2
#+begin_src elisp
(princ "called fun2")
#+end_src

Hi Ian, yes, I can run the top code block *manually* by navigating to that
block and then evaluating it.  I would like to define a keyboard shortcut
that
will call the function and its subheadings' functions.

I don't see an example of calling these blocks programmatically.
I will research the docs a bit more.  Thanks!

What about,

(defun my/eval-parent-subtree()
  (save-excursion
    (outline-up-heading 1)
    (org-babel-execute-subtree)))

And then binding that to some key or something? Or (outline-up-heading 99) if you always want to go to "*". Or make that line a bit more dynamically controllable by use of 'prefix-arg' ?

  -k.
