Dist::Zilla::Role::Bootstrap - Shared logic for bootstrap things.


version 1.001003


For consuming plugins:

    use Moose;
    with 'Dist::Zilla::Role::Bootstrap';

    sub bootstrap {
        my $bootstrap_root = $_[0]->_bootstrap_root;
        # Do the actual bootstrap work here

For users of plugins:

    try_built = 0 ; # use / as the root to bootstrap
    try_built = 1 ; # try to use /Dist-Name-.*/ instead of /

    fallback  = 0 ; # don't bootstrap at all if /Dist-Name-.*/ matches != 1 things
    fallback  = 1 ; # fallback to / if /Dist-Name-.*/ matches != 1 things


This module is a role that aims to be consumed by plugins that want to perform some very early bootstrap operation that may affect the loading environment of successive plugins, especially with regards to plugins that may wish to build with themselves, either by consuming the source tree itself, or by consuming a previous built iteration.

Implementation is quite simple:

1. with this role in your plugin
  with 'Dist::Zilla::Role::Bootstrap'
2. Implement the bootstrap sub.
  sub bootstrap {
    my ( $self ) = @_;
3. Optional: Fetch the discovered bootstap root via:
4. Optional: Load some path into @INC via:



Any user specified bootstrap method will be invoked during plugin_from_config.

This is AFTER ->new, AFTER ->BUILD, and AFTER dzil's internal plugin_from_config steps.

This occurs within the register_component phase of the plug-in loading and configuration.

This also occurs BEFORE Dist::Zilla attaches the plug-in into the plug-in stash.



The name of the distribution.

This value is vivified by asking zilla->name.

Usually this value is populated by dist.ini in the property name

However, occasionally, this value is discovered by a plugin.

In such a case, that plugin cannot be bootstrapped, because that plugin MUST be loaded prior to bootstrap.


This attribute controls how the consuming plugin behaves.

  • false (default) : bootstrapping is only done to PROJECTROOT/lib

  • true : bootstrap attempts to try PROJECTROOT/<distname>-<version>/lib


This attribute is for use in conjunction with try_built

  • false : When PROJECTROOT/<distname>-<version> does not exist, don't perform any bootstrapping

  • true (default) : When PROJECTROOT/<distname>-<version> does not exist, bootstrap to PROJECTROOT/lib


This attribute controls how try_built behaves when multiple directories exist that match PROJECTROOT/<distname>-.*

Two valid options at this time:

  • mtime (default) : Pick the directory with the most recent mtime

  • parseversion : Attempt to parse versions on all candidate directories and use the one with the largest version.

Prior to 0.2.0 this property did not exist, and default behavior was to assume 0 Candidates and 2 or more Candidates were the same problem.
