Question

Relating to a GP project I have a lot of auto-generated lisp snippets that can look basically like this:

(+ 2 (f1 (f2 x y) (f2 x y)))

In short: loads of one-liners.

How would one go about plotting this graphically into a function tree? Preferably by generating graphs in dot or something similar that can easily be shoved through graphviz so that i can render it into something like this:

       +
      / \
     /   \
    2     f1
         /  \
        /    \
       /      \
      /        \
     f2         f2
    /  \       /  \
   /    \     /    \
  x      y   x      y

Answer 1

I made a quick&dirty perl script that does what i need. Placing it here in case someone else could use it:

NB: You’re not allowed to laugh at the ugly code, and it only handles the most basic things, so it might require some hacking to do anything more than what i need it for.
