NAME Role::TinyCommons::Tree - Roles related to object tree VERSION This document describes version 0.128 of Role::TinyCommons::Tree (from Perl distribution Role-TinyCommons-Tree), released on 2021-10-07. DESCRIPTION This distribution provides several roles you can use to create a tree class. The roles are designed for maximum reusability and minimum clashes with your existing class. To create a tree class, all you need to do is apply the Role::TinyCommons::Tree::Node role: use Role::Tiny::With; with 'Role::TinyCommons::Tree::Node'; The Tree::Node common role just requires you to have two methods: "parent" (which should return parent node object) and "children" (which should return a list or arrayref of children node objects). Utility methods such as "descendants", "walk", "is_first_child" and so on are separated to Role::TinyCommons::Tree::NodeMethods which you can apply if you want. The actual methods in Role::TinyCommons::Tree::NodeMethods are actually implemented in Code::Includable::Tree::NodeMethods, so you can import them to your class manually or just call the routines as a normal function call if you do not want to involve Role::Tiny. See an example of this usage in Data::CSel. HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at . SEE ALSO There are some other general purpose tree modules CPAN, for example Tree::Simple or Data::Tree, but at the time of this writing there isn't a tree role. AUTHOR perlancar CONTRIBUTING To contribute, you can send patches by email/via RT, or send pull requests on GitHub. Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2021, 2020, 2016 by perlancar .
