YamlReaderTask

Parses a YAML file, whose path is set in the options, and iterates over its root elements.

Task reference

  • Service: CleverAge\ProcessBundle\Task\File\Yaml\YamlReaderTask
  • Iterable task

Accepted inputs

Input is ignored

Possible outputs

mixed: the value of each root element of the parsed file, one per iteration (keys are not output). Underlying method is Symfony Yaml::parseFile().

Options

Code Type Required Default Description
file_path string X Path of the YAML file to read. An \UnexpectedValueException is thrown at initialization if the file does not exist

Examples

# Task configuration level
read_yaml:
  service: '@CleverAge\ProcessBundle\Task\File\Yaml\YamlReaderTask'
  options:
    file_path: '%kernel.project_dir%/var/data/data.yaml'
  outputs: [process_item]

Notes

  • The root of the file must be a mapping or a sequence, otherwise an \InvalidArgumentException is thrown (e.g. for an empty file). An empty root mapping or sequence ({} or []) raises a \TypeError.
  • The current root key is added to the error context of the process as iterator_key.
