       String::TT - use TT to interpolate lexical variables


         use String::TT qw/tt strip/;

         sub foo {
            my $self = shift;
            return tt 'my name is [% %]!';

         sub bar {
            my @args = @_;
            return strip tt q{
               Args: [% args_a.join(",") %]


       String::TT exports a "tt" function, which takes a TT (Template Toolkit) template as its
       argument.  It uses the current lexical scope to resolve variable references.  So if you

         my $foo = 42;
         my $bar = 24;

         tt '[% foo %] <-> [% bar %]';

       the result will be "42 <-> 24".

       TT provides a slightly less rich namespace for variables than perl, so we have to do some
       mapping.  Arrays are always translated from @array to "array_a" and hashes are always
       translated from %hash to "hash_h".  Scalars are special and retain their original name,
       but they also get a "scalar_s" alias.  Here's an example:

         my $scalar = 'scalar';
         my @array  = qw/array goes here/;
         my %hash   = ( hashes => 'are fun' );

         tt '[% scalar %] [% scalar_s %] [% array_a %] [% hash_h %]';

       There is one special case, and that's when you have a scalar that is named like an
       existing array or hash's alias:

         my $foo_a = 'foo_a';
         my @foo   = qw/foo array/;

         tt '[% foo_a %] [% foo_a_s %]'; # foo_a is the array, foo_a_s is the scalar

       In this case, the "foo_a" accessor for the "foo_a" scalar will not be generated.  You will
       have to access it via "foo_a_s".  If you delete the array, though, then "foo_a" will refer
       to the scalar.

       This is a very cornery case that you should never encounter unless you are weird.  99% of
       the time you will just use the variable name.


       None by default, but "strip" and "tt" are available.


   tt $template
       Treats $template as a Template Toolkit template, populated with variables from the current
       lexical scope.

   strip $text
       Removes a leading empty line and common leading spaces on each line.  For example,

         strip q{
           This is a test.
            This is indented.

       Will yield the string "This is a test\n This is indented.\n".

       This feature is designed to be used like:

         my $data = strip tt q{
             This is a [% template %].
             It is easy to read.

       Instead of the ugly heredoc equivalent:

         my $data = tt <<'EOTT';
       This is a [% template %].
       It looks like crap.


       If you want to pass args to the TT engine, override the "_build_tt_engine" function:

         local *String::TT::_build_tt_engine = sub { return Template->new( ... ) }
         tt 'this uses my engine';
