`aiida.cmdline`#

The command line interface of AiiDA.

Package Contents#

Classes#

`AbsolutePathParamType`	The ParamType for identifying absolute Paths (derived from click.Path).
`CalculationParamType`	The ParamType for identifying Calculation entities or its subclasses
`CodeParamType`	The ParamType for identifying Code entities or its subclasses
`ComputerParamType`	The ParamType for identifying Computer entities or its subclasses
`ConfigOptionParamType`	ParamType for configuration options.
`DataParamType`	The ParamType for identifying Data entities or its subclasses
`DynamicEntryPointCommandGroup`	Subclass of `click.Group` that loads subcommands dynamically from entry points.
`EmailType`	Parameter whose values have to correspond to a valid email address format.
`EntryPointType`	Parameter whose values have to be valid Python entry point strings.
`FileOrUrl`	Extension of click’s File-type to include URLs.
`GroupParamType`	The ParamType for identifying Group entities or its subclasses.
`HostnameType`	Parameter corresponding to a valid hostname (or empty) string.
`IdentifierParamType`	An extension of click.ParamType for a generic identifier parameter. In AiiDA, orm entities can often be identified by either their ID, UUID or optionally some LABEL identifier. This parameter type implements the convert method, which attempts to convert a value passed to the command for a parameter with this type, to an orm entity. The actual loading of the entity is delegated to the orm class loader. Subclasses of this parameter type should implement the orm_class_loader method to return the appropriate orm class loader, which should be a subclass of aiida.orm.utils.loaders.OrmEntityLoader for the corresponding orm class.
`LabelStringType`	Parameter accepting valid label strings.
`LazyChoice`	This is a delegate of click’s Choice ParamType that evaluates the set of choices lazily. This is useful if the choices set requires an import that is slow. Using the vanilla click.Choice will call this on import which will slow down verdi and its autocomplete. This type will generate the choices set lazily through the choices property
`MpirunCommandParamType`	Custom click param type for mpirun-command
`MultipleValueParamType`	An extension of click.ParamType that can parse multiple values for a given ParamType
`NodeParamType`	The ParamType for identifying Node entities or its subclasses
`NonEmptyStringParamType`	Parameter whose values have to be string and non-empty.
`PathOrUrl`	Extension of click’s Path-type to include URLs.
`PluginParamType`	AiiDA Plugin name parameter type.
`ProcessParamType`	The ParamType for identifying ProcessNode entities or its subclasses
`ProfileParamType`	The profile parameter type for click.
`ShebangParamType`	Custom click param type for shebang line
`UserParamType`	The user parameter type for click. Can get or create a user.
`VerdiCommandGroup`	Subclass of `click.Group` for the `verdi` CLI.

class aiida.cmdline.DataParamType(sub_classes=None)#

Bases: aiida.cmdline.params.types.identifier.IdentifierParamType

The ParamType for identifying Data entities or its subclasses

Initialization

Construct the parameter type, optionally specifying a tuple of entry points that reference classes that should be a sub class of the base orm class of the orm class loader. The classes pointed to by these entry points will be passed to the OrmEntityLoader when converting an identifier and they will restrict the query set by demanding that the class of the corresponding entity matches these sub classes.

To prevent having to load the database environment at import time, the actual loading of the entry points is deferred until the call to convert is made. This is to keep the command line autocompletion light and responsive. The entry point strings will be validated, however, to see if the correspond to known entry points.

Parameters:: sub_classes – a tuple of entry point strings that can narrow the set of orm classes that values will be mapped upon. These classes have to be strict sub classes of the base orm class defined by the orm class loader

name = 'Data'#

property orm_class_loader#

Return the orm entity loader class, which should be a subclass of OrmEntityLoader. This class is supposed to be used to load the entity for a given identifier

class aiida.cmdline.DynamicEntryPointCommandGroup(command, entry_point_group: str, entry_point_name_filter='.*', **kwargs)#

Bases: aiida.cmdline.groups.verdi.VerdiCommandGroup

Subclass of click.Group that loads subcommands dynamically from entry points.

A command group using this class will automatically generate the sub commands from the entry points registered in the given entry_point_group. The entry points can be additionally filtered using a regex defined for the entry_point_name_filter keyword. The actual command for each entry point is defined by command, which should take as a first argument the class that corresponds to the entry point. In addition, it should accept kwargs which will be the values for the options passed when the command is invoked. The help string of the command will be provided by the docstring of the class registered at the respective entry point. Example usage:

def create_instance(cls, **kwargs):
    instance = cls(**kwargs)
    instance.store()
    echo.echo_success(f'Created {cls.__name__}<{instance.pk}>')

@click.group('create', cls=DynamicEntryPointCommandGroup, command=create_instance,)

class aiida.cmdline.LazyChoice(get_choices)#

Bases: click.ParamType

This is a delegate of click’s Choice ParamType that evaluates the set of choices lazily. This is useful if the choices set requires an import that is slow. Using the vanilla click.Choice will call this on import which will slow down verdi and its autocomplete. This type will generate the choices set lazily through the choices property

class aiida.cmdline.ProfileParamType(*args, **kwargs)#

Bases: aiida.cmdline.params.types.strings.LabelStringType

The profile parameter type for click.

This parameter type requires the command that uses it to define the context_class class attribute to be the aiida.cmdline.groups.verdi.VerdiContext class, as that is responsible for creating the user defined object obj on the context and loads the instance config.

Initialization

name = 'profile'#

static deconvert_default(value)#

convert(value, param, ctx)#: Attempt to match the given value to a valid profile.

shell_complete(ctx, param, incomplete)#

Return possible completions based on an incomplete value

class aiida.cmdline.VerdiCommandGroup#

Bases: click.Group

Subclass of click.Group for the verdi CLI.

The class automatically adds the verbosity option to all commands in the interface. It also adds some functionality to provide suggestions of commands in case the user provided command name does not exist.

context_class = None#

static add_verbosity_option(cmd)#: Apply the verbosity option to the command, which is common to all verdi commands.

fail_with_suggestions(ctx, cmd_name)#: Fail the command while trying to suggest commands to resemble the requested cmd_name.

get_command(ctx, cmd_name)#

Return the command that corresponds to the requested cmd_name.

This method is overridden from the base class in order to two functionalities:

If the command is found, automatically add the verbosity option.

If the command is not found, attempt to provide a list of suggestions with existing commands that resemble the requested command name.

Note that if the command is not found and resilient_parsing is set to True on the context, then the latter feature is disabled because most likely we are operating in tab-completion mode.

group(*args, **kwargs)#: Ensure that sub command groups use the same class but do not override an explicitly set value.

class aiida.cmdline.WorkflowParamType#

Bases: aiida.cmdline.params.types.identifier.IdentifierParamType

The ParamType for identifying WorkflowNode entities or its subclasses

name = 'WorkflowNode'#

property orm_class_loader#

Return the orm entity loader class, which should be a subclass of OrmEntityLoader. This class is supposed to be used to load the entity for a given identifier

Returns:: the orm entity loader class for this ParamType

aiida.cmdline.dbenv()#

Loads the dbenv for a specific region of code, does not unload afterwards

Only use when it makes it possible to avoid loading the dbenv for certain code paths

Good Example:

# do this
@click.command()
@click.option('--with-db', is_flag=True)
def profile_info(with_db):
    # read the config file
    click.echo(profile_config)

    # load the db only if necessary
    if with_db:
        with dbenv():
            # gather db statistics for the profile
            click.echo(db_statistics)

This will run very fast without the –with-db flag and slow only if database info is requested

Do not use if you will end up loading the dbenv anyway

Bad Example:

# don't do this
def my_function():
    with dbenv():
        # read from db

    # do db unrelated stuff

aiida.cmdline.echo_critical(message: str, bold: bool = False, nl: bool = True, err: bool = True, prefix: bool = True) → None#

Log a critical error message to the cmdline logger and exit with exit_status.

This should be used to print messages for errors that cannot be recovered from and so the script should be directly terminated with a non-zero exit status to indicate that the command failed.

Parameters:

message – the message to log.
bold – whether to format the message in bold.
nl – whether to add a newline at the end of the message.
err – whether to log to stderr.
prefix – whether the message should be prefixed with a colored version of the log level.

Log the given dictionary to stdout in the given format

Parameters:

dictionary – the dictionary
fmt – the format to use for printing
sort_keys – Whether to automatically sort keys

aiida.cmdline.echo_error(message: str, bold: bool = False, nl: bool = True, err: bool = True, prefix: bool = True) → None#

Log an error message to the cmdline logger.

Parameters:

message – the message to log.
bold – whether to format the message in bold.
nl – whether to add a newline at the end of the message.
err – whether to log to stderr.
prefix – whether the message should be prefixed with a colored version of the log level.

aiida.cmdline.echo_info(message: str, bold: bool = False, nl: bool = True, err: bool = False, prefix: bool = True) → None#

Log an info message to the cmdline logger.

Parameters:

message – the message to log.
bold – whether to format the message in bold.
nl – whether to add a newline at the end of the message.
err – whether to log to stderr.

Log an report message to the cmdline logger.

Parameters:

message – the message to log.
bold – whether to format the message in bold.
nl – whether to add a newline at the end of the message.
err – whether to log to stderr.
prefix – whether the message should be prefixed with a colored version of the log level.

aiida.cmdline.echo_success(message: str, bold: bool = False, nl: bool = True, err: bool = False, prefix: bool = True) → None#

Log a success message to the cmdline logger.

Note

The message will be logged at the REPORT level and always with the Success: prefix.

Parameters:

message – the message to log.
bold – whether to format the message in bold.
nl – whether to add a newline at the end of the message.
err – whether to log to stderr.
prefix – whether the message should be prefixed with a colored version of the log level.

aiida.cmdline.format_call_graph(calc_node, max_depth: int = None, info_fn=calc_info)#

Print a tree like the POSIX tree command for the calculation call graph

Parameters:

calc_node – The calculation node
max_depth – Maximum depth of the call graph to print
info_fn – An optional function that takes the node and returns a string of information to be displayed for each node.

aiida.cmdline.is_verbose()#: Return whether the configured logging verbosity is considered verbose, i.e., equal or lower to INFO level.

Note

This checks the effective logging level that is set on the CMDLINE_LOGGER. This means that it will consider the logging level set on the parent AIIDA_LOGGER if not explicitly set on itself. The level of the main logger can be manipulated from the command line through the VERBOSITY option that is available for all commands.

aiida.cmdline.only_if_daemon_running(echo_function=echo.echo_critical, message=None)#

Function decorator for CLI command to print critical error and exit automatically when daemon is not running.

The error printing and exit behavior can be controlled with the decorator keyword arguments. The default message that is printed can be overridden as well as the echo function that is to be used. By default it uses the aiida.cmdline.utils.echo.echo_critical function which automatically aborts the command. The function can be substituted by for example aiida.cmdline.utils.echo.echo_warning to instead print just a warning and continue.

Example:

@only_if_daemon_running(echo_function=echo.echo_warning, message='beware that the daemon is not running')
def create_node():
    pass

Parameters:

echo_function – echo function to issue the message, should be from aiida.cmdline.utils.echo
message – optional message to override the default message

aiida.cmdline.with_dbenv()#

Function decorator that will load the database environment for the currently loaded profile.

Note

if no profile has been loaded yet, the default profile will be loaded first.

Example:

@with_dbenv()
def create_node():
    from aiida.orm import Int  # note the local import
    node = Int(1).store()
