NAME

Dist::Zilla::Role::RequireFromBuild - Role to require() from build files

VERSION

This document describes version 0.006 of Dist::Zilla::Role::RequireFromBuild (from Perl distribution Dist-Zilla-Role-RequireFromBuild), released on 2017-01-09.

SYNOPSIS

In your plugin's preamble, include the role:

 with 'Dist::Zilla::Role::RequireFromBuild';

Then in your plugin subroutine, e.g. munge_files():

 $self->require_from_build("Foo/Bar.pm");
 $self->require_from_build("Baz::Quux");

DESCRIPTION

Since build files are not necessarily on-disk files, but might also be in-memory files or files with munged content, we cannot use require() directly. require_from_build() is like Perl's require() except it looks for files not from @INC but from build files $self->zilla->files. It searches libraries in lib/ and ..

$self->require_from_build("Foo/Bar.pm") or $self->require_from_build("Foo::Bar") is a convenient shortcut for something like:

 return if exists $INC{"Foo/Bar.pm"};

 my @files = grep { $_->name eq "lib/Foo/Bar.pm" } @{ $self->zilla->files };
 @files    = grep { $_->name eq "Foo/Bar.pm" }     @{ $self->zilla->files } unless @files;
 die "Can't find Foo/Bar.pm in lib/ or ./ in build files" unless @files;

 eval $files[0]->encoded_content;
 die if $@;

 $INC{"Foo/Bar.pm"} = "(set by Dist::Zilla::Role::RequireFromBuild, loaded from build file)";

METHODS

$obj->require_from_build($file)
