NAME

re2c – convert regular expressions to C/C++

SYNOPSIS

re2c [OPTIONS] FILE

DESCRIPTION

re2c is a lexer generator for C/C++. It finds regular expression specifications inside of C/C++ comments and replaces them with a hard-coded DFA. The user must supply some interface code in order to control and customize the generated DFA.

EXAMPLE

Given the following code: 



unsigned int stou(const char *s)

{

#define YYCTYPE char

    const YYCTYPE *YYCURSOR = s;

    unsigned int result = 0;

    for (;;) {

        /*!re2c

            re2c:yyfill:enable = 0;

            "
