.SH "NAME"
String::TT \- use TT to interpolate lexical variables
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  use String::TT qw/tt strip/;
\&
\&  sub foo {
\&     my $self = shift;
\&     return tt \*(Aqmy name is [% self.name %]!\*(Aq;
\&  }
\&
\&  sub bar {
\&     my @args = @_;
\&     return strip tt q{
\&        Args: [% args_a.join(",") %]
\&     }
\&  }
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
String::TT exports a \f(CW\*(C`tt\*(C'\fR function, which takes a \s-1TT\s0
(Template Toolkit) template as its argument.  It uses the
current lexical scope to resolve variable references.  So if you say:
.PP
.Vb 2
\&  my $foo = 42;
\&  my $bar = 24;
\&
\&  tt \*(Aq[% foo %] <\-> [% bar %]\*(Aq;
.Ve
.PP
the result will be \f(CW\*(C`42 <\-> 24\*(C'\fR.
.PP
\&\s-1TT\s0 provides a slightly less rich namespace for variables than perl, so
we have to do some mapping.  Arrays are always translated from
\&\f(CW@array\fR to \f(CW\*(C`array_a\*(C'\fR and hashes are always translated from \f(CW%hash\fR
to \f(CW\*(C`hash_h\*(C'\fR.  Scalars are special and retain their original name, but
they also get a \f(CW\*(C`scalar_s\*(C'\fR alias.  Here's an example:
.PP
.Vb 3
\&  my $scalar = \*(Aqscalar\*(Aq;
\&  my @array  = qw/array goes here/;
\&  my %hash   = ( hashes => \*(Aqare fun\*(Aq );
\&
\&  tt \*(Aq[% scalar %] [% scalar_s %] [% array_a %] [% hash_h %]\*(Aq;
.Ve
.PP
There is one special case, and that's when you have a scalar that is
named like an existing array or hash's alias:
.PP
.Vb 2
\&  my $foo_a = \*(Aqfoo_a\*(Aq;
\&  my @foo   = qw/foo array/;
\&
\&  tt \*(Aq[% foo_a %] [% foo_a_s %]\*(Aq; # foo_a is the array, foo_a_s is the scalar
.Ve
.PP
In this case, the \f(CW\*(C`foo_a\*(C'\fR accessor for the \f(CW\*(C`foo_a\*(C'\fR scalar will not
be generated.  You will have to access it via \f(CW\*(C`foo_a_s\*(C'\fR.  If you
delete the array, though, then \f(CW\*(C`foo_a\*(C'\fR will refer to the scalar.
.PP
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.
.SH "EXPORT"
.IX Header "EXPORT"
None by default, but \f(CW\*(C`strip\*(C'\fR and \f(CW\*(C`tt\*(C'\fR are available.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.ie n .SS "tt $template"
.el .SS "tt \f(CW$template\fP"
.IX Subsection "tt $template"
Treats \f(CW$template\fR as a Template Toolkit template, populated with variables
from the current lexical scope.
.ie n .SS "strip $text"
.el .SS "strip \f(CW$text\fP"
.IX Subsection "strip $text"
Removes a leading empty line and common leading spaces on each line.
For example,
.PP
.Vb 4
\&  strip q{
\&    This is a test.
\&     This is indented.
\&  };
.Ve
.PP
Will yield the string \f(CW"This is a test\en This is indented.\en"\fR.
.PP
This feature is designed to be used like:
.PP
.Vb 4
\&  my $data = strip tt q{
\&      This is a [% template %].
\&      It is easy to read.
\&  };
.Ve
.PP
Instead of the ugly heredoc equivalent:
.PP
.Vb 4
\&  my $data = tt <<\*(AqEOTT\*(Aq;
\&This is a [% template %].
\&It looks like crap.
\&EOTT
.Ve
.SH "HACKING"
.IX Header "HACKING"
If you want to pass args to the \s-1TT\s0 engine, override the
\&\f(CW\*(C`_build_tt_engine\*(C'\fR function:
.PP
.Vb 2
\&  local *String::TT::_build_tt_engine = sub { return Template\->new( ... ) }
\&  tt \*(Aqthis uses my engine\*(Aq;
