 | `use_dot_match` | `false` | `"true"` | Whether or not to use dot-matching when searching for files - `"true"` or `"false"` - If this is true, directories like `.github`, etc will be searched |
 | `json_schema` | `false` | `""` | The full path to the JSON schema file (e.g. ./schemas/schema.json) - Default is `""` which doesn't enforce a strict schema |

 | `json_extension` | `false` | `".json"` | The file extension for JSON files (e.g. .json) |
 | `json_exclude_regex` | `false` | `""` | A regex to exclude files from validation (e.g. `".*\.schema\.json$"` to exclude all files ending with `.schema.json`) - Default is `""` which doesn't exclude any files |
 | `use_ajv_formats` | `false` | `"true"` | Whether or not to use the [AJV formats](https://github.com/ajv-validator/ajv-formats) with the JSON processor |
