Puppet Strings JSON Data
Puppet Strings has two flags to the generate action that can be used to emit JSON data:
--emit-json <file>: Emits the JSON data to the given file.--emit-json-stdout: Emits the JSON data to STDOUT.
Document Schema
At the top level, there are five arrays in the JSON document:
| Document Key | Description |
|---|---|
| puppet_classes | The list of Puppet classes that were parsed. |
| defined_types | The list of defined types that were parsed. |
| resource_types | The list of resource types that were parsed. |
| providers | The list of resource providers that were parsed. |
| puppet_functions | The list of Puppet functions (3.x, 4.x and Puppet language) that were parsed. |

Each entry in the puppet_classes list is an object with the following attributes:
| Attribute Key | Description |
|---|---|
| name | The name of the Puppet class. |

| docstring | The DocString object for the class (see below). |
| defaults | The map of parameter names to default values. |
| source | The Puppet source code for the class. |
Defined Types
Each entry in the defined_types list is an object with the following attributes:
| Attribute Key | Description |
|---|---|
| name | The name of the defined type. |

Resource Types
Each entry in the resource_types list is an object with the following attributes:
| Attribute Key | Description |
|---|---|
| name | The name of the resource type. |

Each entry in the parameters list is an object with the following attributes:
| Attribute Key | Description |
|---|---|
| name | The name of the parameter. |
| description | The description of the parameter. |
| values | The array of acceptable string values for the parameter. |
| aliases | The map of new values aliased to existing values. |

| default | The default value for the parameter. |
Each entry in the features list is an object with the following attributes:
| Attribute Key | Description |
|---|---|
| name | The name of the feature. |
| description | The description of the feature. |
Providers
Each entry in the providers list is an object with the following attributes:
| Attribute Key | Description |
|---|---|
| name | The name of the provider. |
| type_name | The name of the resource type of the provider. |
| file | The file defining the provider. |
| line | The line where the provider is defined. |

| confines | The string map of confines for the provider. |
| features | The list of features implemented by the provider. |
| defaults | The string map of "default for" for the provider. |
| commands | The string map of commands for the provider. |
Puppet Functions
Each entry in the puppet_functions list is an object with the following attributes:
| Attribute Key | Description |
|---|---|
| name | The name of the function. |
| file | The file defining the provider. |
| line | The line where the provider is defined. |
| type | The function type (e.g. ruby3x, ruby4x, puppet). |
| signature | The Puppet signature of the function (no overloads). |
| docstring | The DocString object for the function (see below). |
| defaults | The map of parameter names to default values. |
| source | The source code for the function. |
DocString Objects
For the above types, their docstrings are represented as an object with the following attributes:
| Attribute Key | Description DocString |
|---|---|
| text | The textual part of the DocString. |
| tags | The array of tag objects, if any are present. |
Each entry in the tags list is an object with the following properties:
| Attribute Key | Description |
|---|---|
| tag_name | The name of the tag (e.g. param, return, etc.). |
| text | The descriptive text of the tag. |
| types | The array of types associated with the tag. |
| name | The name associated with the tag (e.g. parameter name). |
For Puppet 4.x functions with overloads, overload tags will contain three additional attributes:
| Attribute Key | Description |
|---|---|
| signature | The Puppet signature of the overload. |
| docstring | The DocString object describing the overload. |
| defaults | The map of parameter names to default values. |
