# libtmux

libtmux is a [typed](https://docs.python.org/3/library/typing.html) 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](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.

[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
>>> 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:

```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 ...)
```

Find session by dict lookup:

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

Control your session:

```python
>>> 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):

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

Close window:

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

Grab remaining tmux window:

```python
>>> window = session.attached_window
>>> window.split_window(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_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):

```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 ...)
```
