Parser generator ( UltraGram )

UltraGram is an advanced 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
• Advanced diagnostics. Detailed information about all problems that happen in the parser development process
• Parsing conflicts resolution. Clear and understandable graphical representation of all possible parsing conflicts
• DFA graph. Visualization of the DFA graph in its conventional form
• Run-Time diagnostics. Detection of runtime errors that can not be found during grammar development stage
• Parsing error recovery. Advanced error detection and recovery mechanism
• Full UNICODE and internationalization support
• Multiple parsing algorithms. Full support for the following parsing algorithms: LALR(1), LR(1), GLR
• Multiple target languages. Ability to generate parser code in several programming languages including: C++, Java, C#, VB.NET
