Grammar Editor is a tool for students learning about context-free grammars. It computes parse trees based on a grammar you define: Just type the grammar into the ``Grammar:'' area, type the sentence you want to parse into the ``Text:'' field, and then click the ``Parse'' button. The program computes and displays the parse tree for the text.
Grammar Editor should run on any platform having Java 1.4. The program is released under the GNU General Public License, version 2.
