This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.

find 

        # Pathname.find

(from ruby core)
---
    find(ignore_error: true) { |pathname| ... }

---

Iterates over the directory tree in a depth first manner, yielding a
Pathname for each file under "this" directory.

Returns an Enumerator if no block is given.

Since it is implemented by the standard library module Find, Find.prune
can be used to control the traversal.

If `self` is `.`, yielded pathnames begin with a filename in the current
directory, not `./`.

See Find.find
