# cf.CoordinateReference.creation_commands¶

CoordinateReference.creation_commands(namespace=None, indent=0, string=True, name='c', header=True)[source]

Return the commands that would create the coordinate reference construct.

New in version (cfdm): 1.8.7.0

Parameters
namespace: str, optional

The name space containing classes of the cf package. This is prefixed to the class name in commands that instantiate instances of cf objects. By default, or if None, the name space is assumed to be consistent with cf being imported as import cf.

Parameter example:

If cf was imported as import cf as xyz then set namespace='xyz'

Parameter example:

If cf was imported as from cf import * then set namespace=''

indent: int, optional
Indent each line by this many spaces. By default no

indentation is applied. Ignored if string is False.

string: bool, optional

If False then return each command as an element of a list. By default the commands are concatenated into a string, with a new line inserted between each command.

header: bool, optional

If False then do not output a comment describing the components.

name: str, optional

The name of the CoordinateReference instance created by the returned commands.

Parameter example:

name='var1'

header: bool, optional

If False then do not output a comment describing the components.

Returns
str or list

The commands in a string, with a new line inserted between each command. If string is False then the separate commands are returned as each element of a list.

Examples:

>>> x = cf.CoordinateReference(
...     coordinates=['dimensioncoordinate0']
... )
>>> x.coordinate_conversion.set_parameters(
...     {'standard_name', 'atmosphere_hybrid_height_coordinate',
...      'computed_standard_name', 'altitude'}
... )
>>> x.coordinate_conversion.set_domain_ancillaries(
...     {'a': 'domainancillary0',
...      'b': 'domainancillary1',
...      'orog': 'domainancillary2'}
... )
