------- Additional comments from [EMAIL PROTECTED] Tue Aug 22 08:57:49 -0700 2006 ------- I may be missing something, but the IEEE document that er posted specifies the regular expression for regexec and regcomp only, and does not specify the syntax for replace. Back references in this document appears to discuss references in the match pattern only. IMHO, We've already had this discussion and decided that implementing a replace without an '&' does not follow convention. Since there is no dispute over the definition of '&' in the replace string, I believe we should not be trying to change this behavior. Here is the behavior of Perl, PHP, and sed using the '&' and '\0' substitution patters for the string "123 ABC DEF GHI": perl -> 's/123 (AB). (DE). (GH)./$&' -> '123 ABC DEF GHI' perl -> 's/123 (AB). (DE). (GH)./$0' -> '_' sed -> 's/123 \(AB\). \(DE\). \(GH\)./&' -> '123 ABC DEF GHI' sed -> 's/123 \(AB\). \(DE\). \(GH\)./\0' -> '123 ABC DEF GHI' php -> 's/123 (AB). (DE). (GH)./&/' -> '&' php -) 's/123 (AB). (DE). (GH)./\0/' -> '123 ABC DEF GHI' Note: while php and sed support the '\0' behavior, perl does not support '$0'. Only Microsoft replaces '\0' with all the matched subgroups. This creates a dilemma since Microsoft users expect one behavior and the open source world expects another. The best of all worlds would support two syntaxes and allow the user to select between them. I can see having a replace check box option labeled "use Microsoft replace" that would change the behavior to use the complete Microsoft syntax. For the time being, I suggest that we try to stick with GNU sed, Perl, and PHP and support both '&' and '\0' for whole string replace and revisit Microsoft compatibility at a later date. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
