RSyntaxTree: yet another syntax tree generator in Ruby

RSyntaxTree is a graphical syntax tree generator written in the Ruby programming language. It is basically a port of phpSyntaxTree created by André Eisenbach.

While phpSyntaxTree does not accept multi-byte characters as those in Chinese, Japanese, and Korean, RSyntaxTree handles text of any language as long as encoded in UTF-8 and fonts have been installed. Additionally, RSyntaxTree can output symmetrized tree diagrams, a functionality that is not implemented in phpSyntaxTree.

RSyntaxTree consists of an easy-to-use command-line app and a web-based interfaces made with Sinatra web framework.

Web Interface

Working web interface of a previous version of RSyntaxTree is available at http://yohasebe.com/rsyntaxtree . New version will be deployed soon.

Installation
