Hi

Don't know if this is trivially answered...

I'm thinking about using org-mode for a collection of code-snippets which
are executed by a click on a link

My first idea was to use orgs hyperlink syntax but there I have two problems
1. something like [[shell:code][NAME]] can't be multiline
2. for  perl  code I'll need to escape certain characters when using
[[shell:...] or [[elisp:...]

my second idea was org-babel, but AFAI see
1. it seems to execute code-snippets only when exporting
2. the code can't be hidden behind a NAME in a link text

Is there a way to combine both ways?

A hyperlink which executes a codesnippet (which is per default folded away)?

something like?

* [[exec:following snippet][name]
#+begin_src perl
for $i (1..9){
   print $i;
}
#+end_src


or


* Title
#+begin_src perl :hyperlink name
for $i (1..9){
   print $i;
}
#+end_src



Thanks for any help

      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

        Hi Eric
        
        Thanks looks promising but I'm having problems to use it.
        
        I noticed that babel is not a part of 6.30trans and did an upgrade to the
        latest current version 7.4.
        
        Unfortunately it's causing problems (all I did was updating a sym-link to
        the new package)
        
        Am I supposed to set additional PATHs?

            Hi Eric
            
            thanks, after some fiddling I was able to make it work...
            
            But do I get it right?
            
            The snippet has to be explicitely named, I can't tell the hyperlink just to
            take the next block?
            
            Before I start trying it, is it theoretically possible to write an on
            ob-multiline.el which parses the following lines?
            
            I.e. is the current "point" known at execution time?
            
            Out of curiosity, the manual says
            
            > The org-babel-load-languages controls which languages are enabled for
            evaluation (by default only emacs-lisp is enabled).
            
            Is it done out of security reasons? Cause it wouldn't be a problem to start
            a  process via elisp and (shell-command ...)
            
            Next question:
            
            shell-command normally prints the stdout into the minibuffer, but
            org-hyperlink executions overwrite it with the return code.
            
            Is this behaviour configurable?
            
            Thanks for the help
              Rolf
            
            PS: ob-perl.el says
            -----
            (defun org-babel-perl-initiate-session (&optional session params)
              "Return nil because sessions are not supported by perl"
            nil)
            ------
            What is meant with supporting sessions? IIRC do packages like sepia.el fork
            a perl process allowing bidirectional communication with emacs.
            
            Or what kind of extra support is neccessary here?

              it works.
              
              
              I managed to create a new lisp defun which parses the following text,
              extracts the code and executes it!
              
              perfect! =)
