"""
Run abstract code in the group's namespace. The created `CodeRunner`
object will be automatically added to the group, it therefore does not
need to be added to the network manually. However, a reference to the
object will be returned, which can be used to later remove it from the
group or to set it to inactive.
Parameters
----------
code : str
The abstract code to run.
dt : `Quantity`, optional
The time step to use for this custom operation. Cannot be combined
with the `clock` argument.
clock : `Clock`, optional
The update clock to use for this operation. If neither a clock nor
the `dt` argument is specified, defaults to the clock of the group.
when : str, optional
When to run within a time step, defaults to the ``'start'`` slot.
See :ref:`scheduling` for possible values.
name : str, optional
A unique name, if non is given the name of the group appended with
'run_regularly', 'run_regularly_1', etc. will be used. If a
name is given explicitly, it will be used as given (i.e. the group
name will not be prepended automatically).
codeobj_class : class, optional
The `CodeObject` class to run code with. If not specified, defaults
to the `group`'s ``codeobj_class`` attribute.
Returns
-------
obj : `CodeRunner`
A reference to the object that will be run.
