Re: hyperlinks executing multiline code snippets?

["Eric Schulte" <schulte.eric@gmail.com>]

Hi LanX,

The following two options come to mind, although I'm not sure if any are
exactly what you're after.

* named code block and a #+call: line
#+source: counter
#+begin_src perl :results output :var to=5
for $i (1..$to){
   print $i;
}
#+end_src

#+results: counter
: 12345

#+call: counter(to=3)

#+results: counter(to=3)
: 123

C-c C-c on the call line to execute the counter block, the block does
not need to be located near the call line, and using the Library of
Babel could even be located in another file.

* using an elisp link
[[elisp:(sbe counter (to "8"))][count to 8]]

Clicking on the link above will also call the code block.

Best -- Eric
