# Asset Catalog parser

## Input

The assets parser accepts one (or more) asset catalogs, which it'll parse for supported set types and groups. We currently support the following types:
- Group Type
- Color Set Type (colorset)
- Image Set Type (imageset)

For a full documentation of asset catalog types, please read the [Apple documentation](https://developer.apple.com/library/content/documentation/Xcode/Reference/xcode_ref-Asset_Catalog_Format/AssetTypes.html).

## Output

The output context has the following structure:

 - `catalogs`: `Array` — list of asset catalogs
   - `name`  : `String` — the name of the catalog
   - `assets`: `Array` — tree structure of items, each item either
     - represents a group and has the following entries:
       - `type` : `String` — "group"
       - `name` : `String` — name of the folder
       - `items`: `Array` — list of items, can be either groups, colors or images
     - represents a color asset, and has the following entries:
       - `type` : `String` — "color"
       - `name` : `String` — name of the color
       - `value`: `String` — the actual full name for loading the color
     - represents an image asset, and has the following entries:
       - `type` : `String` — "image"
       - `name` : `String` — name of the image
       - `value`: `String` — the actual full name for loading the image
