Dist::Zilla::Role::PERLANCAR::WriteModules - Role to write modules to disk to a specified directory


This document describes version 0.02 of Dist::Zilla::Role::PERLANCAR::WriteModules (from Perl distribution Dist-Zilla-Role-PERLANCAR-WriteModules), released on 2015-07-27.


Rationale: in the middle of a build process, sometimes we want to write the built version of modules to disk (as actual files). The problem is, Dist::Zilla writes the dist to disk at the end of build.

An example of this is with Dist::Zilla::Plugin::GenPericmdScript which generates scripts in the file gathering step. Or, Dist::Zilla::Plugin::Depak which replaces scripts with packed version in the file munging step. These generated scripts might embed modules inside them, including from the current dist we're building, and we need the built version of these modules instead of the raw version.

So this role can be used to write the built modules (so far, at that point) to a temporary directory.


written_modules_dir => str

If already written modules to dir, will contain the directory name. Otherwise, undef.

has_written_modules_to_dir => bool


$obj->write_modules_to_dir([ $dir[, $force ] ])

Write built modules to disk at the specified directory (or, to a temporary directory if $dir is not specified).

To find out the directory being used, use the written_modules_dir attribute.

If a temporary directory is automatically selected, it will automatically be cleaned up at the end of build (created using File::Temp's tempdir with CLEANUP set to 1) unless the environment DEBUG is set to true, in which case the temporary directory will not be automatically cleaned up.

By default will only do this once during build, and subsequent call to write_modules_to_dir() will be a no-op. But if you set $force to 1, will write modules to disk even if it has been done previously during the same build.




Dist::Zilla::Dist::Builder the module which dzil uses to write the dist and archive to disk, usually at the end of build.
