# Colonel Kurtz

Colonel Kurtz is a content editor written in
[React](http://facebook.github.io/react/). It forces content to be
broken up into individual types, such as a photo or chunk of text, and
provides a user interface for managing those "blocks" of content,
reordering them, and even nesting them inside other content.

Comprehensive documentation can be found under the [`./docs`](https://github.com/vigetlabs/colonel-kurtz/tree/master/docs) directory
of this repo. However the content that follows should provide a high
level overview:

## Data format

Colonel Kurtz can be serialized down to JSON. This structure looks like:

```json
[
  {
    "blocks": [],
    "content": {
      "html": "<p>This is introductory text.<br></p>",
      "text": "This is introductory text."
    },
    "type": "medium"
  },
  {
    "blocks": [
      {
        "blocks": [],
        "content": {
          "src": "http://fizbuz.com/image.jpg"
        },
        "type": "image"
      },
      {
        "blocks": [],
        "content": {
          "html": "<p>Sweet, sweet content.<br></p>",
          "text": "Sweet, sweet content."
        },
        "type": "medium"
      }
    ],
    "type": "section"
  },
  {
    "blocks": [],
    "content": {
      "html": "<p>This is footer text.<br></p>",
      "text": "This is footer text."
    },
    "type": "medium"
  }
]
```

A block has three important pieces of information:

1.  **content**: A map of information captured about a block. This
    could be display settings, rich text, etc.
2.  **type**: Blocks are created within a given block type (more on
    this later). This block type has an identifier which is stored at
    this key (type). This is used to communicate how content should be
    displayed and how the editor should expose the content for
    modification.
3.  **blocks**: A block can have child blocks, stored as an array. The structure of child
    blocks is exactly the same as top-level blocks.

## Configuring

More thorough documentation can be found at
[`./docs/colonel.md`](https://github.com/vigetlabs/colonel-kurtz/blob/master/docs/colonel.md)
however at a high level, Colonel Kurtz is installed with code loosely following:

```javascript
import ColonelKurtz from 'colonel-kurtz'
import BlockType from './path/to/react/component'

var container = document.querySelector('#container')
var input = document.querySelector('#input')

var editor = new ColonelKurtz({
  el: container,
  blocks: JSON.parse(input.value),
  blockTypes: [
    {
      id: 'a-block',
      label: 'This is a block',
      component: BlockType
    }
  ]
})
```
