Dr Parse description
Dr Parse is a powerful program that deploys LR-DFA and LR1 language independent parse generators

Dr Parse is a powerful program that deploys LR-DFA and LR1 language independent parse generators with capabilities to support multiple DFA/LR parse engines in a single application. Dr Parse's grammar and rich set of utilities, tools, C/C++ Parser Foundation Classes (PFC - source optional) parse engines, coupled with complete error and grammar statistics is the key to accelerated parser development and quality.

Using Dr Parse to design and debug your next parser, will cut your development time to a mere fraction. In fact, you can create a new template project and have a simple expression parser built in less than 15 minutes.

Are you building a special language and would like to accelerate your design? Great, Dr Parse™ includes the LR-Parse Generators/Debuggers and has with over 30,000 lines of ANSI C/C++ code (optional) designed to accelerate your language development and have complete control. The source code is completely ANSI C/C++ compatible and can be ported to any platform supporting an ANSI C/C++ compiler.

Dr Parse's grammar is designed to work synergistically with semantic actions, node insertion, node deletion, operator manipulation, and error recovery which is coupled with the String, Keyword, Symbol, Type, DAG classes supplied by the Parser Foundation Classes, PFC or your own set of foundation classes.
Note: Dr Parse Pro includes full C/C++ PFC Source
Note: Dr Parse Std includes C/C++ PFC headers and Libraries. No Source

In any case, deploying Dr Parse will significantly enhance your ability to develop faster, more robust parsing applications in less time for Compilers, Languages and Data Parsing applications.

Dr Parse performs the task of reading from a source grammar and constructing the appropriate parse tables. This information is saved to a file or embedded into a language which is later used by the parse engine.
