exception libtmux.exc.MultipleObjectsReturned

Bases:

• LibTmuxException

A lookup expected one object and matched several.

Raised by get . Unlike ObjectDoesNotExist , a default does **not** suppress it: a default is a stand-in for an object that is *absent*, and an ambiguous lookup is not an absent one. Silently answering with one of several equally valid matches is how you end up driving the wrong pane.

On a server-wide collection, several matches for a single id is ordinary and means the window is linked into more than one session. See winlinks for what to do about it.

Examples

Copy

>>> from libtmux import exc
>>> str(exc.MultipleObjectsReturned())
'Multiple objects returned'

A lookup that matched too much reports how much, and for what:

Copy

>>> str(exc.MultipleObjectsReturned(count=2, query={"pane_id": "%0"}))
"Multiple objects returned (2): pane_id='%0'"

It is part of the LibTmuxException hierarchy, so except LibTmuxException catches it:

Copy

>>> issubclass(exc.MultipleObjectsReturned, exc.LibTmuxException)
True
