REAL

REAL (Regular Expression Analyzer) is a prototype tool for checking the determinism of regular expressions. Techniques may be used to assist writing deterministic expressions in designing XML Schema and so on. The main functionalities: Check the determinism of the expressions. Locate and give diagnostic information of non-determinism. Give counter-example. Give more detailed information for analysis, such as syntax tree , first set and so on. Auto-generate a deterministic expression when the non-deterministic expression denotes a deterministic language. Developed with MFC Tested on Windows XP and Windows 7
