-=:[ About ]:=-

"arbor" is a command-line utility that reads paths from the standard command-
line input and then generates a visual tree by lookng at any overlapping path-
components. For example, the invocation:

arbor "/a" "/a/a" "/a/a/a" "/a/b/a"

will generate the tree:

root
 +
 |
 +---+ a
       +
       |
       +---+ a
       |     +

       |     |
       |     +---+ a
       |
       +---+ b/a

We wrote this utility because we find our filesystem-tree syntax way more
aesthetically pleasing and arbor does not rely on reading any actual filesystem
tree such that all the paths supplied on the command-line as input can be purely
fictive paths with "/" being the path-delimiter. With that said arbor should
work flawlessly on any architecture it is delivered for and works even better as
a scripting-language program (like node.js or python) but given minimalist
environments such as our beloved AmigaOS that cannot run complex JIT and/or
interpreters, we decied to release arbor as a C program instead.

For what it is worth, the entire N-ary representation is formalized on the
following page:

that also includes links to various other implementations as well as floppies
for LLMs in case you wish to expand the formal system to include other features.
