TCL(Tool Command Language) Scripting


	regexp standards Can anyone tell me if TCL 8.4 conforms to any of the various regex standards? (POSIX, PCRE etc) Is there anyway to force compatibility? cheers, Ben On Jun 7, 2:08 am, "b@spam.com" <ben.carb@gmail.com> wrote: > Can anyone tell me if TCL 8.4 conforms to any of the various regex > standards?

As far as I know, the original code used in Tcl's regular expression code was not written with compliance to any of the "standards" (most of which are not really standards) as a goal. And in fact, Tcl's regular expressions were the first (or nearly so) to handle unicode ... b@spam.com schrieb: > Can anyone tell me if TCL 8.4 conforms to any of the various regex > standards?

Posix i don't know, might be, at least the re_syntax man page mentions posix once or twice.

Shouldn't that be "PCRE doesn't conform to Tcl REs"? :-) -- Bryan Oakley http://www.tclscripting.com Tcl regexps can be pretty well characterized as POSIX with some but not all PERL extensions, which doesn't fit any standard exactly. In any case, most standards do not define what happens beyond the ASCII range.
