libtmux

libtmux is a typed Python library that provides a wrapper for interacting programmatically with tmux, a terminal multiplexer. You can use it to manage tmux servers, sessions, windows, and panes. Additionally, libtmux powers 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
>>> svr = libtmux.Server()
>>> svr
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.

Run any tmux command, respective of context:

Honors tmux socket name and path:

>>> server = Server(socket_name='libtmux_doctest')
>>> server.cmd('display-message', 'hello world')
<libtmux...>

New session:

>>> server.cmd('new-session', '-d', '-P', '-F#{session_id}').stdout[0]
'$2'

>>> session.cmd('new-window', '-P').stdout[0]
'libtmux...:2.0'

From raw command output, to a rich Window object (in practice and as shown later, you'd use Session.new_window()):

>>> Window.from_window_id(window_id=session.cmd('new-window', '-P', '-F#{window_id}').stdout[0], server=session.server)
Window(@2 2:..., Session($1 libtmux_...))

Create a pane from a window:

>>> window.cmd('split-window', '-P', '-F#{pane_id}').stdout[0]
'%2'

Raw output directly to a Pane:

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

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 ...)

Filter sessions:

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

Control your session:

>>> session
Session($1 ...)

>>> session.rename_session('my-session')
Session($1 my-session)

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

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

# Session can search the window
>>> session.windows.filter(window_name__startswith="ha")
[Window(@... 2:ha in the bg, Session($1 ...))]

# Directly
>>> session.windows.get(window_name__startswith="ha")
Window(@... 2:ha in the bg, Session($1 ...))

# Clean up
>>> bg_window.kill()

Close window:

>>> w = session.active_window
>>> w.kill()

Grab remaining tmux window:

>>> window = session.active_window
>>> window.split(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()
>>> pane = window.split(attach=False)
>>> pane.select()
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(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))  # doctest: +SKIP
$ cowsay 'hello'
 _______
< hello >
 -------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||
...

Traverse and navigate:

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