Arboretum

Arboretum is a project to explore the potential of displaying expressions and their types as visual trees in a browsers. In the course of this project, we have begun building a new functional language, TreeScript (working name).

Technologies

All of the language type checking and evaluation, as well as the rendering, is performed in Elm. Lexing and Parsing is handled by Chevrotain, a parsing library written in Javascript.

Building

After cloning the git repo, make sure you download Chevrotain, our parsing library:

npm install chevrotain

Also make sure you download browserify, which we use to bundle all of the projects dependencies.

npm install -g browserify

To build the webpage, two javascript files need to be built: main.js containing the compiled Elm code, and bundle.js containing the parser and its dependencies. The bash script makearb.sh automates the process, so run it now, and after any changes to Elm or JavaScript code to propagate the changes into the webpage.
