Hi all,
is it possible to have babel add debugging lines during execution?
Consider this example with an enabled debug property:
#+PROPERTY: session *R*
#+PROPERTY: debug yes
* Some code blocks
#+name: codeA
#+begin_src R
sum(1)
#+end_src
#+name: codeB
#+begin_src R
sum(2)
#+end_src
When executing the subtree with C-c C-v s, for example, I'd like babel to
automatically add some print() statements, so that executed is
,----
| print("entering codeA")
| sum(1)
| print("leaving codeA")
|
| print("entering codeB")
| sum(2)
| print("leaving codeB")
`----
As there is a print statement in most languages, this should be possible
quite universal for any language.
Also handy would be the insertion of breakpoints
(maybe #+PROPERTY: interactive-debug yes)
In R that would lead to the execution of:
,----
| browser()
| sum(1)
|
| browser()
| sum(2)
`----
Are these things possible?
(Or better question: How are these things possible?)
Regards,
Andreas
