Rémi Verschelde d8223ffa75 Welcome in 2017, dear changelog reader! 
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer
with state-of-the-art rendering techniques tuned to work as low as middle
end handheld devices - without compromising with the possibilities given
for higher end desktop games of course. Great times ahead for the Godot
community and the gamers that will play our games!

NREX: Node RegEx

Build Status

** Version 0.2 **

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 . (includes newlines)
  • Shorthand caracter classes \w\W\s\S\d\D
  • POSIX character classes such as [[:alnum:]]
  • Bracket expressions such as [A-Za-z]
  • Simple quantifiers ?, * and +
  • Range quantifiers {0,1}
  • Lazy (non-greedy) quantifiers *?
  • Begining ^ and end $ anchors
  • Word boundaries \b
  • Alternation |
  • ASCII \xFF code points
  • Unicode \uFFFF code points
  • Positive (?=) and negative (?!) lookahead
  • Positive (?<=) and negative (?<!) lookbehind (fixed length and no alternations)
  • Backreferences \1 and \g{1} (limited by default to 9 - can be unlimited)
