By default, \fIP\fR is \f(CW\*(C`qr/.*?\eS/\*(C'\fR. In Regexp::Common 0.02 or earlier, the default pattern was \f(CW\*(C`qr/.*?/\*(C'\fR. But that will match a single space, causing unintended parsing of \f(CW\*(C`a, b, and c\*(C'\fR as a list of four elements instead of 3 (with \f(CW\*(C`\-word\*(C'\fR being \f(CW\*(C`(?:and)\*(C'\fR). One consequence is that a list of the form \*(L"a,,b\*(R" will no longer be parsed. Use the pattern \f(CW\*(C`qr /.*?/\*(C'\fR to be able to parse this, but see the previous remark. .PP If \f(CW\*(C`\-sep=\f(CIP\f(CW\*(C'\fR is specified, it defines the pattern \fIP\fR to be used as a separator between each pair of substrings in the list, except the final two. By default \fIP\fR is \f(CW\*(C`qr/\es*,\es*/\*(C'\fR. .PP If \f(CW\*(C`\-lastsep=\f(CIP\f(CW\*(C'\fR is specified, it defines the pattern \fIP\fR to be used as a separator between the final two substrings in the list. By default \fIP\fR is the same as the pattern specified by the \f(CW\*(C`\-sep\*(C'\fR flag. .PP For example: .PP .Vb 4 \& $RE{list}{\-pat=>\*(Aq\ew+\*(Aq} # match a list of word chars \& $RE{list}{\-pat=>$RE{num}{real}} # match a list of numbers \& $RE{list}{\-sep=>"\et"} # match a tab\-separated list \& $RE{list}{\-lastsep=>\*(Aq,\es+and\es+\*(Aq} # match a proper English list .Ve .PP Under \f(CW\*(C`\-keep\*(C'\fR: .ie n .IP "$1" 4 .el .IP "\f(CW$1\fR" 4 .IX Item "$1" captures the entire list .ie n .IP "$2" 4 .el .IP "\f(CW$2\fR" 4 .IX Item "$2" captures the last separator .ie n .SS "$RE{list}{conj}{\-word=\f(CIPATTERN\fP}" .el .SS "\f(CW$RE{list}{conj}{\-word=\fP\f(CIPATTERN\fP\f(CW}\fP" .IX Subsection "$RE{list}{conj}{-word=PATTERN}" An alias for \f(CW$RE{list}{\-lastsep=>\*(Aq\es*,?\es*\f(CIPATTERN\f(CW\es*\*(Aq}\fR .PP If \f(CW\*(C`\-word\*(C'\fR is not specified, the default pattern is \f(CW\*(C`qr/and|or/\*(C'\fR. .PP For example: .PP .Vb 2 \& $RE{list}{conj}{\-word=>\*(Aqet\*(Aq} # match Jean, Paul, et Satre \& $RE{list}{conj}{\-word=>\*(Aqoder\*(Aq} # match Bonn, Koln oder Hamburg .Ve .ie n .SS "$RE{list}{and}" .el .SS "\f(CW$RE{list}{and}\fP" .IX Subsection "$RE{list}{and}" An alias for \f(CW$RE{list}{conj}{\-word=>\*(Aqand\*(Aq}\fR .ie n .SS "$RE{list}{or}" .el .SS "\f(CW$RE{list}{or}\fP" .IX Subsection "$RE{list}{or}" An alias for \f(CW$RE{list}{conj}{\-word=>\*(Aqor\*(Aq}\fR .SH "SEE ALSO" .IX Header "SEE ALSO" Regexp::Common for a general description of how to use this interface. .SH "AUTHOR" .IX Header "AUTHOR" Damian Conway (damian@conway.org) .SH "MAINTENANCE" .IX Header "MAINTENANCE" This package is maintained by Abigail (\fIregexp\-common@abigail.be\fR). .SH "BUGS AND IRRITATIONS" .IX Header "BUGS AND IRRITATIONS" Bound to be plenty. .PP For a start, there are many common regexes missing.
