The general 2004-07-12T07:35:59Z Tim J. Robbins tjr@FreeBSD.org 2004-07-12T07:35:59Z urn:sha1:e5996857ad1f30f74f848a2c464c75a7ae28e59a idea is that we perform multibyte->wide character conversion while parsing and compiling, then convert byte sequences to wide characters when they're needed for comparison and stepping through the string during execution. As with tr(1), the main complication is to efficiently represent sets of characters in bracket expressions. The old bitmap representation is replaced by a bitmap for the first 256 characters combined with a vector of individual wide characters, a vector of character ranges (for [A-Z] etc.), and a vector of character classes (for [[:alpha:]] etc.). One other point of interest is that although the Boyer-Moore algorithm had to be disabled in the general multibyte case, it is still enabled for UTF-8 because of its self-synchronizing nature. This greatly speeds up matching by reducing the number of multibyte conversions that need to be done. Add a new error code, REG_ILLSEQ, to indicate that a regular expression 2004-07-12T06:07:26Z Tim J.
