=head1 NAME

Alien::Build::Interpolate - Advanced interpolation engine for Alien builds

=head1 VERSION

version 2.84

=head1 CONSTRUCTOR

=head2 new

 my $intr = Alien::Build::Interpolate->new;

=head2 add_helper

 $intr->add_helper($name => $code);
 $intr->add_helper($name => $code, %requirements);

=head2 replace_helper

 $intr->replace_helper($name => $code);
 $intr->replace_helper($name => $code, %requirements);

=head2 has_helper

 my $coderef = $intr->has_helper($name);

Used to discover if a helper exists with the given name.
Returns the code reference.

=head2 execute_helper

 my $value = $intr->execute_helper($name);

This evaluates the given helper and returns the result.

=head2 interpolate

 my $string = $intr->interpolate($template, $build);
 my $string = $intr->interpolate($template);

This takes a template and fills in the appropriate values of any helpers used
in the template.

[version 2.58]

If you pass in an L<Alien::Build> instance as the second argument, you can use
properties as well as helpers in the template.  Example:

 my $patch = $intr->template("%{.install.patch}/foo-%{.runtime.version}.patch", $build);

=head2 requires

 my %requires = $intr->requires($template);

This returns a hash of modules required in order to execute the given template.
The keys are the module names and the values are the versions.  Version will be
set to C<0> if any version is sufficient.

=head2 clone

 my $intr2 = $intr->clone;

This creates a clone of the interpolator.
