How to pass shell command result to :post source-block?

How to pass shell command result to :post source-block?

[stardiviner]

I want to processing the shell ANSI escaping characters correctly or
just filter them out for display result correctly in Emacs.

Here is my try:

#+NAME: ansi-escape-filter
#+begin_src emacs-lisp
(ansi-color-apply-on-region (point-min) (point-max))
#+end_src

#+begin_src sh :dir /sudo:: :post ansi-escape-filter
sudo tree /var/spool/postfix/
#+end_src

#+RESULTS[<2019-01-19 10:58:39> f6d16244322abbd4fbe01bfaa084ac6bdd66a62c]:
: nil

The second source block's result is supposed to be result of command
=sudo tree /var/spool/postfix/= instead of =nil=.

Can someone help me how to do this correctly?

I solved my own problem.

Here is the complete code:

#+NAME: ansi-escape-filter
#+begin_src emacs-lisp :var data=""
(with-temp-buffer
  (insert data)
  (ansi-color-apply-on-region (point-min) (point-max))
  (buffer-substring-no-properties (point-min) (point-max)))
#+end_src

#+begin_src sh :dir /sudo:: :post ansi-escape-filter(data=*this*) :results output
sudo tree /var/spool/postfix/
#+end_src

See the code below:

#+NAME: ansi-escape-filter
#+begin_src emacs-lisp :var data=""
(with-temp-buffer
  (insert data)
  (ansi-color-apply-on-region (point-min) (point-max))
  (buffer-string))
#+end_src

#+RESULTS: ansi-escape-filter

#+begin_src sh :dir /sudo::  :results output :post  ansi-escape-filter(data=*this*)
tree /var/spool/postfix/
#+end_src

`:results output` is needed to avoid parsing the shell output as a
table.
`data=*this*` is needed to pass the output to `ansi-escape-filter`. You
can also check the example in the org info page for the :post header
argument.


Best,
Ihor

Thanks for your detailed explanation. After your hint, I just checked
out =org-manual.org= about the Post-processing :post example. It's a
good example.
