eval source blocks in a subtree when opening file

eval source blocks in a subtree when opening file

[Tamas Papp]

Hi,

I have a file that looks like this (stylized):

--8<---------------cut here---------------start------------->8--- 
* Setup :noexport:

  #+COMMENT: some code here I want to run every time I open the 
  file in SRC blocks

* Experiment 1

  #+COMMENT: code I run when necessary, not every time

* Experiment 2

  #+COMMENT: code I run when necessary, not every time

* end of file :noexport: #+COMMENT: This is just for local 
variables, not exported.   # Local Variables: # 
org-confirm-babel-evaluate: nil # org-export-babel-evaluate: 
'inline-only # End: --8<---------------cut 
here---------------end--------------->8--- 

I would like to do the following: whenever I open the file in 
Emacs, I would like to eval all the source blocks under the 
heading Setup.

I have found org-babel-execute-subtree, but I cannot figure out 
how to call it on the subtree "Setup" from a local eval.

Best,

Tamas

Name the first block in the subtree "start setup" (say).

Then

# Local Variables:
# eval: (org-babel-goto-named-src-block "start setup")
# eval: (org-babel-execute-subtree)
# End:


should do it.

HTH,

Chuck

Thanks! I found that I can also assign an ID to the section, and then
use

# eval: (progn (org-id-goto ...some-id...) (org-babel-execute-subtree))

It looks like I need the progn for it to work reliably (don't know why).

I am wondering if it would be possible to break a line in Local
Variables, but

# eval: (progn (org-id-goto ...some-id...) \
#              (org-babel-execute-subtree))

didn't work.

Best,

Tamas

Ditch the line continuation character.  This works in my hands with emacs 24.4.1 to set foo to bar:

# Local Variables:
# eval: (setq foo
#   "bar")
# End:
