DESCRIPTION

    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.

ATTRIBUTES

 written_modules_dir => str

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

 has_written_modules_to_dir => bool

METHODS

 $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.

SEE ALSO

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