Hello,
is possible to update the “#+RESULTS: pid” when the block “#+NAME:
echo-pid” is evaluated in the following snippet?
This will lead to a consistent document generation with “M-x
org-babel-execute-buffer” or by hitting “C-c C-c” on “#+NAME:
echo-pid”. Using the cache does not make sense: the process is
generating different output every time.
The info at “M-: (info "(org) Specific header arguments")” does not
mention something useful.
* Intro
** pid
#+NAME: pid
#+BEGIN_SRC shell :results value :cache no
printf '%s' "${$}"
#+END_SRC
The following result is usually outdated/inconsistent!
#+RESULTS: pid
: 25272
** echo pid
#+NAME: echo-pid
#+BEGIN_SRC shell :var DATA=pid :results value
printf '%s' "${DATA}"
#+END_SRC
#+RESULTS: echo-pid
: 25273
The code block in pid is evaluated every time, but the results are
used only to populate the pid variable and non for updating the
results in the buffer:
#+BEGIN_EXAMPLE
executing Shell code block (pid)...
Wrote /tmp/babel-4889iZN/ob-input-4889CyZ
"25273"
executing Shell code block (echo-pid)...
Wrote /tmp/babel-4889iZN/ob-input-48892ay
Code block evaluation complete.
#+END_EXAMPLE
This was tested with Org-mode version 8.3.4 release_8.3.4-705-g716e33.
Thanks in advance for your suggestions,
Daniele
