Custom Filter Plugins for Infinito.Nexus¶
This directory contains custom Ansible filter plugins used within the Infinito.Nexus project.
When to Use a Filter Plugin¶
Transform values: Use filters to transform, extract, reformat, or compute values from existing variables or facts.
Inline data manipulation: Filters are designed for inline use in Jinja2 expressions (in templates, tasks, vars, etc.).
No external lookups: Filters only operate on data you explicitly pass to them and cannot access external files, the Ansible inventory, or runtime context.
Examples¶
{{ role_name | get_entity_name }}
{{ my_list | unique }}
{{ user_email | regex_replace('^(.+)@.*$', '\\1') }}
When not to Use a Filter Plugin¶
If you need to load data from an external source (e.g., file, environment, API), use a lookup plugin instead.
If your logic requires access to inventory, facts, or host-level information that is not passed as a parameter.
