DFASTAR Lexer Generator
"A DFA lexer generator, reading a lexical grammar." EditByBSEditor: DFASTAR is a DFA lexer generator, which reads a Lexical grammar and generates a DFA state machine in C/C++ source code that is capable of identifying the tokens defined in the lexical grammar. DFASTAR creates very fast lexers. It has 2 options for choosing lexer size: 'ts' for small and 'tm' for medium. The medium size lexers are about 10% FASTER than the small lexers. High-performance LexersA lot of research and effort was put into DFASTAR for creating fast lexers. As a result, the C/C++ Lexer Speed Test shows that a DFASTAR lexer can process 31,286,000 tokens per second (in memory) when reading C/C++ source code. In this test, a DFASTAR lexer was 85% faster than a lexer created by FLEX. When using the 'tm' option of DFASTAR, the generated lexer reads 34,290,000 tokens per second.Small LexersIn the C/C++ test, DFASTAR g
