Bases: pydantic_settings.BaseSettings

Root class for HERMES configuration model.

model_config: Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].

logging: Dict

class hermes.commands.base.HermesCommand(parser: argparse.ArgumentParser)

Bases: abc.ABC

Base class for a HERMES workflow command.

Variables:: NAME – The name of the sub-command that is defined here.

command_name: str = ''

settings_class: Type

parser

plugins

settings = None

log

errors = []

init_plugins(): Collect and initialize the plugins available for the HERMES command.

classmethod derive_settings_class(setting_types: Dict[str, Type]) → None

Build a new Pydantic data model class for configuration.

This will create a new class that includes all settings from the plugins available.

init_common_parser(parser: argparse.ArgumentParser) → None

Initialize the common command line arguments available for all HERMES sub-commands.

Parameters:: parser – The base command line parser used as entry point when reading command line arguments.

init_command_parser(command_parser: argparse.ArgumentParser) → None

Initialize the command line arguments available for this specific HERMES sub-commands.

You should override this method to add your custom arguments to the command line parser of the respective sub-command.

Parameters:: command_parser – The command line sub-parser responsible for the HERMES sub-command.

load_settings(args: argparse.Namespace): Load settings from the configuration file (passed in from command line).

patch_settings(args: argparse.Namespace): Process command line options for the settings.

abstract __call__(args: argparse.Namespace)

Execute the HERMES sub-command.

Parameters:: args – The namespace that was returned by the command line parser when reading the arguments.

class hermes.commands.base.HermesPlugin

Bases: abc.ABC

Base class for all HERMES plugins.

settings_class: Type | None = None

abstract __call__(command: HermesCommand) → None

Execute the plugin.

Parameters:: command – The command that triggered this plugin to run.

class hermes.commands.base.HermesHelpSettings(/, **data: Any)

Bases: pydantic.BaseModel

Usage docs: https://docs.pydantic.dev/2.10/concepts/models/

A base class for creating Pydantic models.

__class_vars__: The names of the class variables defined on the model.

__private_attributes__: Metadata about the private attributes of the model.

__signature__: The synthesized __init__ [Signature][inspect.Signature] of the model.

__pydantic_complete__: Whether model building is completed, or if there are still undefined fields.

__pydantic_core_schema__: The core schema of the model.

__pydantic_custom_init__: Whether the model has a custom __init__ function.

__pydantic_decorators__: Metadata containing the decorators defined on the model. This replaces Model.__validators__ and Model.__root_validators__ from Pydantic V1.

__pydantic_generic_metadata__: Metadata for generic models; contains data used for a similar purpose to __args__, __origin__, __parameters__ in typing-module generics. May eventually be replaced by these.

__pydantic_parent_namespace__: Parent namespace of the model, used for automatic rebuilding of models.

__pydantic_post_init__: The name of the post-init method for the model, if defined.

__pydantic_root_model__: Whether the model is a [RootModel][pydantic.root_model.RootModel].

__pydantic_serializer__: The pydantic-core SchemaSerializer used to dump instances of the model.

__pydantic_validator__: The pydantic-core SchemaValidator used to validate instances of the model.

__pydantic_fields__: A dictionary of field names and their corresponding [FieldInfo][pydantic.fields.FieldInfo] objects.

__pydantic_computed_fields__: A dictionary of computed field names and their corresponding [ComputedFieldInfo][pydantic.fields.ComputedFieldInfo] objects.

__pydantic_extra__: A dictionary containing extra values, if [extra][pydantic.config.ConfigDict.extra] is set to ‘allow’.

__pydantic_fields_set__: The names of fields explicitly set during instantiation.

__pydantic_private__: Values of private attributes set on the model instance.
