# boolean-numerify

The *boolean-numerify* **parser** will process boolean values produced by an inner **parser** into a numeric **variable** within a **collection**.

It inherits attributes and behaviors from its parent: **parser** - *numeric*.

The *boolean-numerify* **parser** is a utility wrapper that enables **parsers** which normally produce boolean **variables** to produce a numeric **variable** instead.

## Attribute - true_value

```
{
  "parser_type": "boolean-numerify", 
  "column": {
    "parser_type": "categorical-match",
    "column": "ccc1",
    "value": "match_string"
  },
  
  // The true_value attribute will determine the numeric value
  // assigned to each true value emitted from the inner column parser
  //
  "true_value": ####,
  
  "collection": "collection_name",
  "variable": "variable_name"
}
```

## Attribute - false_value

```
{
  "parser_type": "boolean-numerify", 
  "column": {
    "parser_type": "categorical-match",
    "column": "ccc1",
    "value": "match_string"
  },
  
  // The false_value attribute will determine the numeric value
  // assigned to each false value emitted from the inner column parser
  //
  "false_value": ####,
  
  "collection": "collection_name",
  "variable": "variable_name"
}
```
