# Abstract

nodetree is a development package that visualizes the structure of node lists. nodetree shows its debug informations in the consoles’ output when you compile a Lua file. It uses a similar visual representation for node lists as the UNIX tree command uses for a folder structure.

Node lists are the main building blocks of each document generated by the engine Lua. The package nodetree doesn‘t change the rendered document. The tree view can only be seen when using a terminal to generate the document.

nodetree is inspired by a gist from Patrick Gundlach.
