About
RSyntaxTree is a graphical syntax tree generator written in the Ruby programming language created by Yoichiro Hasebe.
Documentation of the input text syntax and markups of RSyntaxTree is avalable in English and Japanese. See also Example Gallery for different types of sample input and result syntree images.
