Hi All, How do I use chr inside a regex. In the below, how do I get rid of $y? $ p6 'my Str $x=chr(0x66)~chr(0x77); my Str $y=chr(0x66)~chr(0x77); $x~~s/ $y /xy/; say $x;' xy Many thanks, -T

`eq` is string equality `==` is numeric equality a Buf is neither. You want `eqv` (equivalent) $b[2..4] eqv (0x90,0x00,0x04) On Fri, Feb 1, 2019 at 9:37 PM ToddAndMargo via perl6-users wrote: > > On 2/1/19 7:22 PM, ToddAndMargo via perl6-users wrote: > > Hi All, > > > > On a type Buf,

This would work: my $b = Buf.new( 0,0,0, 1, 2, 0 ); my $match = Buf.new( 1, 2 ); $b.rotor( $match.elems => 1 - $match.elems ).grep(* eqv $match.List, :k) If you only need the first one, swap out `grep` for `first` Another iffy option is to decode it as latin1
