# libtmux
`libtmux` is a [typed](https://docs.python.org/3/library/typing.html) 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](http://man.openbsd.org/OpenBSD-5.9/man1/tmux.1#COMMANDS) and
[formats](http://man.openbsd.org/OpenBSD-5.9/man1/tmux.1#FORMATS) to
create an object mapping to traverse, inspect and interact with live
tmux sessions.
View the [documentation](https://libtmux.git-pull.com/),
[API](https://libtmux.git-pull.com/api.html) information and
[architectural details](https://libtmux.git-pull.com/about.html).
# Install
```console
$ pip install --user libtmux
```
# Open a tmux session
Session name `foo`, window name `bar`
```console
$ tmux new-session -s foo -n bar
```
# Pilot your tmux session via python
```console
$ python
```
Use [ptpython], [ipython], etc. for a nice shell with autocompletions:
```console
$ pip install --user ptpython
```
```console
$ ptpython
```
Connect to a live tmux session:
```python
>>> 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.

[`tmuxp shell`]: https://tmuxp.git-pull.com/cli/shell.html
[ptpython]: https://github.com/prompt-toolkit/ptpython
[ipython]: https://ipython.org/
Run any tmux command, respective of context:
Honors tmux socket name and path:
```python
>>> server = Server(socket_name='libtmux_doctest')
>>> server.cmd('display-message', 'hello world')
<libtmux...>
```
New session:
```python
>>> server.cmd('new-session', '-d', '-P', '-F#{session_id}').stdout[0]
'$2'
```
```python
>>> 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()`):
```python
>>> 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:
```python
>>> window.cmd('split-window', '-P', '-F#{pane_id}').stdout[0]
'%2'
```
Raw output directly to a `Pane`:
```python
>>> 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:
```python
>>> server.sessions
[Session($1 ...), Session($0 ...)]
```
Filter sessions by attribute:
```python
>>> server.sessions.filter(history_limit='2000')
[Session($1 ...), Session($0 ...)]
```
Direct lookup:
```python
>>> server.sessions.get(session_id="$1")
Session($1 ...)
```
Filter sessions:
```python
>>> 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:
```python
>>> session
Session($1 ...)
>>> session.rename_session('my-session')
Session($1 my-session)
```
Create new window in the background (don't switch to it):
```python
>>> 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:
```python
>>> w = session.active_window
>>> w.kill()
```
Grab remaining tmux window:
```python
>>> window = session.active_window
>>> window.split(attach=False)
Pane(%2 Window(@1 1:... Session($1 ...)))
```
Rename window:
```python
>>> window.rename_window('libtmuxower')
Window(@1 1:libtmuxower, Session($1 ...))
```
Split window (create a new pane):
```python
>>> 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):
```python
>>> pane.send_keys('echo hey send now')
>>> pane.send_keys('echo hey', enter=False)
>>> pane.enter()
Pane(%1 ...)
```
Grab the output of pane:
```python
>>> 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:
```python
>>> pane.window
Window(@1 1:..., Session($1 ...))
>>> pane.window.session
Session($1 ...)
```
