NAME

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

VERSION

version 2.80

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.
