A graphical interface to visualize tree operations, made in OCaml.

• It draws tree on an empty canvas, using the official Graphics OCaml library. I'm working on a way to parse trees and heaps from a text file.

• opam : necessary to build executable OCaml code.
• dune : a composable build system for OCaml. Basically, it manages dependencies for us. You can get it through opam (the OCaml Package Manager) with :

opam install dune

• Graphics library : since OCaml 4.06, graphics is not part of the stdlib you get by downloading opam anymore. Install it using :

opam install graphics

• Clone the repository wherever you want :

git clone https://github.com/Esteban795/TreeViewer.git

• After you're done cloning it, head to the directory. There, you can test with the given example if everything is running correctly. First, open a terminal and type

eval $(opam env)

to make sure dune will be detected. You'll need to type this every time you start a new terminal, so avoid killing your terminal each time !

• Then, you can just run

dune exec ./test/TreeViewer.exe

• If everything goes according to plan, you should be able to see something this beautiful max_heap :

• Known issue : can't represent big trees, for the simple reason that the screen is static and just can't move.
• Known issue : can't resize without losing the displayed tree. (might have to go the SDL route ?)
