NAME
Dist::Zilla::Plugin::PrecomputeVariable - Precompute variable values during building
VERSION
This document describes version 0.04 of Dist::Zilla::Plugin::PrecomputeVariable (from Perl distribution Dist-Zilla-Plugin-PrecomputeVariable), released on 2016-01-24.
SYNOPSIS
In dist.ini:
[PrecomputeVariable]
variable = $Some::Module::var1
variable = %Some::OtherModule::var2
; add more variables as neededin your module lib/Some/Module.pm:
package Some::Module;
our $var1 = do { some expensive operation }; # PRECOMPUTE
...in your module lib/Some/OtherModule.pm:
package Some::OtherModule;
my %Some::OtherModule::var2 = some_expensive_func(); # PRECOMPUTE
...In the generated lib/Some/Module.pm:
package Some::Module;
our $var1 = ["some", "value"]; # PRECOMPUTED FROM: do { some expensive operation }
...In the generated lib/Some/OtherModule.pm:
package Some::OtherModule;
my %Some::OtherModule::var2 = ("some", "value"); # PRECOMPUTED FROM: some_expensive_func();
...DESCRIPTION
This plugin can be used to precompute variables values during build time and put the resulting computed value into the built source code. This is useful in some cases to reduce module startup time, especially if it takes some time to compute the value.
