Re^2: Variables in extended patterns?

Thanks.

I missed that whitespace will be discarded after variable imterpolation.

About just omitting xms: Of course that's exactly what I did, never mind what some clever guy calls "best practises".

I'm now trying to find documentation on what, exactly, \R does... My perl 5.8.6 lists a few escape-sequences in "man perlop", section "quote and quote-like characters", but not \R.

I said a modern perl. 5.8.6 is four years old. It doesn't have \R. 5.10 does. See 'man perlrebackslash' (yes, you need 5.10 for that as well)	[reply]

You can always write `my $CRE = '0D'; my $LFE = '0A'; s{\x{$CRE}?\x{$LFE}}{\n}xms; s{\015?\012}{\n}xms; s{\x0D\x0A}{\n}xms;` [download] or `my $CRE = '\x0D'; my $LFE = '\x0A'; $_ = qq,aod \x0D\x0A another \x0D\x0A no more,; s/$CRE?$LFE/--/msxg; print; __END__ aod -- another -- no more` [download]	[reply] [d/l] [select]
