Making escape (\) ordinary in double quotes

sg has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

Rather than writing:

  {
      my $foo  =  "Ignore the \\slash, expand $boo.";
  }
[download]

is it possible to do something like:

  {
     # do something to get perl 
     # to treat '\' as an ordinary character
     # so that one may write:

     my $foo  =  "Ignore the \slash, expand $boo.";
  }
[download]

Thanks

sprintf does not alter the interpolation behavior of a double-quoted string, but it does provide all the interpolation capability of double-quoting – and more! See the many format specifiers in the docs. `>perl -wMstrict -le "my $foo = 'Foo'; my $bar = 'Bar'; ;; my $x = sprintf 'ignore \slash, expand %s, %s.', $foo, $bar; print qq{'$x'}; " 'ignore \slash, expand Foo, Bar.'` [download]	[reply] [d/l]

You can use `q/STRING/` `my $foo = q{Ignore the \slash, expand} . $boo;` You can check Quote-Like-Operators If you tell me, I'll forget. If you show me, I'll remember. if you involve me, I'll understand. --- Author unknown to me	[reply] [d/l]

You can concatenate the variable along with the string containing '\' in (') single quote. Ex `my $foo = "Ignore the \slash, expand '.$boo;`	[reply] [d/l]
