aiida.cmdline.params.types package

Provides all parameter types.

class aiida.cmdline.params.types.LazyChoice(get_choices)

Bases: click.types.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

__init__(get_choices)

x.__init__(…) initializes x; see help(type(x)) for signature

__module__ = 'aiida.cmdline.params.types.choice'

__repr__() <==> repr(x)

_click_choice

Get the internal click Choice object that we delegate functionality to. Will construct it lazily if necessary.

Returns:The click Choice Return type:click.Choice

choices

convert(value, param, ctx)

get_metavar(param)

Returns the metavar default for this param if it provides one.

get_missing_message(param)

Optionally might return extra information about a missing parameter.

New in version 2.0.

class aiida.cmdline.params.types.IdentifierParamType(sub_classes=None)

Bases: click.types.ParamType

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.

__abstractmethods__ = frozenset(['orm_class_loader'])

__init__(sub_classes=None)

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

Module for the non empty string parameter type

class aiida.cmdline.params.types.nonemptystring.NonEmptyStringParamType

Bases: click.types.StringParamType

Parameter that cannot be an an empty string.

__module__ = 'aiida.cmdline.params.types.nonemptystring'

__repr__() <==> repr(x)

convert(value, param, ctx)

Converts the value. This is not invoked for values that are None (the missing value).

name = 'nonemptystring'

Click parameter types for paths.

class aiida.cmdline.params.types.path.AbsolutePathParamType(exists=False, file_okay=True, dir_okay=True, writable=False, readable=True, resolve_path=False, allow_dash=False, path_type=None)

Bases: click.types.Path

The ParamType for identifying absolute Paths (derived from click.Path).

__module__ = 'aiida.cmdline.params.types.path'

__repr__() <==> repr(x)

convert(value, param, ctx)

name = 'AbsolutePath'

Click parameter type for AiiDA Plugins.

class aiida.cmdline.params.types.plugin.PluginParamType(group=None, load=False, *args, **kwargs)

Bases: click.types.ParamType

AiiDA Plugin name parameter type.

Parameters:

• group – string or tuple of strings, where each is a valid entry point group. Adding the aiida. prefix is optional. If it is not detected it will be prepended internally.
• load – when set to True, convert will not return the entry point, but the loaded entry point

Usage:

click.option(... type=PluginParamType(group='aiida.calculations')

or:

click.option(... type=PluginParamType(group=('calculations', 'data'))

__init__(group=None, load=False, *args, **kwargs)

Validate that group is either a string or a tuple of valid entry point groups, or if it is not specified use the tuple of all recognized entry point groups.

__module__ = 'aiida.cmdline.params.types.plugin'

__slotnames__ = []

_init_entry_points()

Populate entry point information that will be used later on. This should only be called once in the constructor after setting self.groups because the groups should not be changed after instantiation

complete(ctx, incomplete)

Return possible completions based on an incomplete value

Returns:list of tuples of valid entry points (matching incomplete) and a description

convert(**kwargs)

Convert the string value to an entry point instance, if the value can be successfully parsed into an actual entry point. Will raise click.BadParameter if validation fails.

get_entry_point_from_string(entry_point_string)

Validate a given entry point string, which means that it should have a valid entry point string format and that the entry point unambiguously corresponds to an entry point in the groups configured for this instance of PluginParameterType.

Returns:the entry point if valid Raises:ValueError if the entry point string is invalid

get_missing_message(param)

Optionally might return extra information about a missing parameter.

New in version 2.0.

get_possibilities(incomplete='')

Return a list of plugins starting with incomplete

get_valid_arguments()

Return a list of all available plugins for the groups configured for this PluginParamType instance. If the entry point names are not unique, because there are multiple groups that contain an entry point that has an identical name, we need to prefix the names with the full group name

Returns:list of valid entry point strings

groups

has_potential_ambiguity

Returns whether the set of supported entry point groups can lead to ambiguity when only an entry point name is specified. This will happen if one ore more groups share an entry point with a common name

name = 'plugin'

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

Bases: click.types.ParamType

The profile parameter type for click.

__module__ = 'aiida.cmdline.params.types.profile'

complete(ctx, incomplete)

Return possible completions based on an incomplete value

Returns:list of tuples of valid entry points (matching incomplete) and a description
