Alien::Build::Interpolate(3)

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

VERSION
version 2.83

CONSTRUCTOR

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

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

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

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

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

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

This evaluates the given helper and returns the result.

  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 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);

  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 0 if any version is sufficient.

  clone
 my $intr2 = $intr->clone;

This creates a clone of the interpolator.
