Welcome to the UltraGram home page - an easy parsing solution
        UltraGram is a visual parser generator that provides functionality for creating grammar of a parser, interpreter or compiler, extensively test it and generate parser source code in a preferred programming language. 

Main advantages of the UltraGram are:
  • Simple and user-friendly integrated development environment
  • Detailed information about all problems that happen in the parser development process
  • Clear and understandable graphical representation of all possible parsing conflicts
  • Visualization of DFA graph in its conventional form
  • Detection of runtime errors that can not be found during grammar development stage
  • Advanced error recovery mechanism
  • Full UNICODE and internationalization support
  • Ability to generate parser code in several programming languages including :
C++,     Java,     C#,     VB.NET

        UltraGram uses LALR(1) parsing technique with some GLR type additions that makes if fast and error resistant. The highly optimized parsing engine allows the creation of small and fast parsers that meet all performance requirements in professional software development.

Current release: 3.2.39

        Here is a simple grammar sample that parses HTML text and extracts all email links. All HTML comments will be correctly skipped.
