The Text.Regex documentation at http://www.haskell.org/ghc/docs/latest/html/libraries/regex-compat/Text-Regex.html merely explains that it uses "Uses the POSIX regular expression interface". The Posix regular expressions are also called "extended regular expressions" to distinguish them from the very old "basic regular expressions". An online copy of a the relevant manual page is at http://www.wellho.net/regex/posix.html The specification is at http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html -- Chris _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
