# Genre Collections

The `genre` Default Collection File is used to dynamically create collections based on the genres available in your library.

This file also merges similarly named genres (such as "Sci-Fi", "SciFi" and "Sci-Fi & Fantasy") into one ("Science Fiction")

## Config

The below YAML in your config.yml will create the collections:

```yaml
libraries:
  Movies:
    collection_files:
      - default: genre
  TV Shows:
    collection_files:
      - default: genre
```

## Template Variables

Template Variables can be used to manipulate the file in various ways to slightly change how it works without having to 
make your own local copy.

Note that the `template_variables:` section only needs to be used if you do want to actually change how the defaults 
work. Any value not specified will use its default value if it has one if not it's just ignored.

??? abstract "Variable Lists (click to expand)"

    * **File-Specific Template Variables** are variables available specifically for this Kometa Defaults file.

    * **Shared Template Variables** are additional variables shared across the Kometa Defaults.

    * **Shared Separator Variables** are additional variables available since this Default contains a 
    [Separator](../separators.md).

        1. Each default collection has a `key` [see here]() that you must replace 
        `<<key>>` with when using this template variable.  These keys are found in the table at the top of this page.

    The below is an example config.yml extract with some Template Variables added in to change how the file works.

    ```yaml
    libraries:
      Movies:
        collection_files:
          - default: genre
            template_variables:
              sep_style: red #(1)!
              exclude:
                - Politics #(2)!
                - News #(3)!
              append_addons:
                Horror: #(4)!
                  - Thriller #(5)! # Adds all thriller items to the Horror collection
    ```

    1.  Use the red [Separator Style](../separators.md#separator-styles)
    2.  Do not create a "Politics" collection, and do not include it in any other collections that it may be in as part 
    of an "include"
    3.  Do not create a "News" collection, and do not include it in any other collections that it may be in as part of 
    an "include"
    4.  Create a "Horror" collection, this genre does not need to exist in your library
    5.  Include the "Thriller" genre in the "Horror" collection, the "Thriller" genre must exist in your library if the 
    "Horror" genre does not

## Default Values

Unless you customize them as described above, these collections use default lists and searches to create the collections.

If you are interested in customizing the default values, you can find that information [here](#template-variables).

If you are interested in seeing what those default builders are, you can find that information [here](../sources.md).
