libtmux#

libtmux is a typed python scripting library for tmux. You can use it to command and control tmux servers, sessions, windows, and panes. It is the tool powering tmuxp, a tmux workspace manager.

libtmux builds upon tmux’s target and formats to create an object mapping to traverse, inspect and interact with live tmux sessions.

Install#

$ pip install --user libtmux

Open a tmux session#

Session name foo, window name bar

$ tmux new-session -s foo -n bar

Pilot your tmux session via python#

$ python

Use ptpython, ipython, etc. for a nice shell with autocompletions:

$ pip install --user ptpython

$ ptpython

Connect to a live tmux session:

>>> import libtmux
>>> s = libtmux.Server()
>>> s
Server(socket_path=/tmp/tmux-.../default)

Tip: You can also use tmuxp’s tmuxp shell to drop straight into your current tmux server / session / window pane.

List sessions:

>>> server.sessions
[Session($1 ...), Session($0 ...)]

Filter sessions by attribute:

>>> server.sessions.filter(history_limit='2000')
[Session($1 ...), Session($0 ...)]

Direct lookup:

>>> server.sessions.get(session_id="$1")
Session($1 ...)

Find session by dict lookup:

>>> server.sessions[0].rename_session('foo')
Session($1 foo)
>>> server.sessions.filter(session_name="foo")[0]
Session($1 foo)

Control your session:

>>> session.rename_session('foo')
Session($1 foo)
>>> session.new_window(attach=False, window_name="ha in the bg")
Window(@2 2:ha in the bg, Session($1 foo))
>>> session.kill_window("ha in")

Create new window in the background (don’t switch to it):

>>> session.new_window(attach=False, window_name="ha in the bg")
Window(@2 2:ha in the bg, Session($1 ...))

Close window:

>>> w = session.attached_window
>>> w.kill_window()

Grab remaining tmux window:

>>> window = session.attached_window
>>> window.split_window(attach=False)
Pane(%2 Window(@1 1:... Session($1 ...)))

Rename window:

>>> window.rename_window('libtmuxower')
Window(@1 1:libtmuxower, Session($1 ...))

Split window (create a new pane):

>>> pane = window.split_window()
>>> pane = window.split_window(attach=False)
>>> pane.select_pane()
Pane(%3 Window(@1 1:..., Session($1 ...)))
>>> window = session.new_window(attach=False, window_name="test")
>>> window
Window(@2 2:test, Session($1 ...))
>>> pane = window.split_window(attach=False)
>>> pane
Pane(%5 Window(@2 2:test, Session($1 ...)))

Type inside the pane (send key strokes):

>>> pane.send_keys('echo hey send now')

>>> pane.send_keys('echo hey', enter=False)
>>> pane.enter()
Pane(%1 ...)

Grab the output of pane:

>>> pane.clear()  # clear the pane
Pane(%1 ...)
>>> pane.send_keys("cowsay 'hello'", enter=True)
>>> print('\n'.join(pane.cmd('capture-pane', '-p').stdout))  
$ cowsay 'hello'
 _______
< hello >
 -------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||
...

Traverse and navigate:

>>> pane.window
Window(@1 1:..., Session($1 ...))
>>> pane.window.session
Session($1 ...)
