NREX: Node RegEx

Small node-based regular expression library. It only does text pattern matchhing, not replacement. To use add the files nrex.hpp, nrex.cpp and nrex_config.h to your project and follow the example:

nrex regex;
regex.compile("^(fo+)bar$");

nrex_result captures[regex.capture_size()];
if (regex.match("foobar", captures))
{
	std::cout << captures[0].start << std::endl;
	std::cout << captures[0].length << std::endl;
}

More details about its use is documented in nrex.hpp

Currently supported features:

  • Capturing () and non-capturing (?:) groups
  • Any character .
  • Shorthand caracter classes \w\W\s\S\d\D
  • User-defined character classes such as [A-Za-z]
  • Simple quantifiers ?, * and +
  • Range quantifiers {0,1}
  • Lazy (non-greedy) quantifiers *?
  • Begining ^ and end $ anchors
  • Alternation |
  • Backreferences \1 to \99

To do list:

  • Unicode \uFFFF code points
