NAME

	re2r - POSIX ERE to ragel converter (C) rofl0r

SYNOPSIS

	re2r [OPTIONS]

DESCRIPTION

	reads input from stdin, transforms ERE into a ragel machine,

	emitting a function with a regexec() like signature.

	each input line shall consist of a machine name followed by a regex.

EXAMPLES

	ipv4 [0-9]+[.][0-9]+[.][0-9]+[.][0-9]+

OPTIONS

	-t template.txt: use template.txt instead of builtin (ragel.tmpl)

	-o outfile: write output to outfile instead of stdout

BUGS

	POSIX collation, equivalence, and character classes support is not implemented

	you can replace character classes like [[:digit:]] with [0-9] using some sort

	of preprocessor. see ere.y for more details.
