Windows#

class libtmux.Window[source]#

Bases: Obj

tmux(1) Window [window_manual].

Holds Pane objects.

Parameters:

session (Session) –

Examples

>>> window = session.new_window('My project', attach=True)
>>> window
Window(@2 2:My project, Session($... ...))

Windows have panes:

>>> window.panes
[Pane(...)]
>>> window.active_pane
Pane(...)

Relations moving up:

>>> window.session
Session(...)
>>> window.window_id == session.active_window.window_id

Return type:

Window

Parameters:
  • server (Server) –

property panes: QueryList[Pane]#

Panes contained by window.

Can be accessed via .panes.get() and .panes.filter()

cmd(cmd, *args, target=None)[source]#

Execute tmux subcommand within window context.

Automatically binds target by adding -t for object’s window ID to the command. Pass target to keyword arguments to override.

  • target (str | int | None) –

Examples

Create a pane from a window:

>>> window.cmd('split-window', '-P', '-F#{pane_id}').stdout[0]
'%...'

Magic, directly to a Pane:

>>> Pane.from_pane_id(pane_id=session.cmd(
... 'split-window', '-P', '-F#{pane_id}').stdout[0], server=session.server)
Pane(%... Window(@... ...:..., Session($1 libtmux_...)))
