Hi Dallaylaen,

TT does not cache compiled templates. This can be overcome but not easily.

Just to clarify, I assume you mean that the Template Toolkit does not cache compiled templates *persistently* if they originated as a reference to a string, as you showed.

See the documentation on "Caching and Compiling Options".

You can cache compiled templates in memory explicitly without even processing them using template(): 

$ perl -MTemplate -wE '
my $tt = Template->new;
my $compiled = $tt->template(\"In-place [% foo %] query\n");
my $answer = 40;
$tt->process( $compiled, {foo => $answer++} ) for 0..2;
'
In-place 40 query
In-place 41 query
In-place 42 query

And of course you can cache persistently between program runs if you use the right configuration options (and use a template file or filehandle): 
my $tt = Template->new(
    INCLUDE_PATH => '/some/path',
    COMPILE_DIR  => '/other/path',
    COMPILE_EXT  => '.compiled',
);

my $file = 'foo.tt';
my $data = { foo => 42 };

$tt->process( $file, $data ) or die $tt->error;
# Template will be compiled and cached at '/other/path/foo.tt.compiled
+'
# and that file will be used until '/some/path/foo.tt' changes

I'm sure you knew this, just clarifying for future readers...


The way forward always starts with a minimal test.
