libtmux 0.45.x (Yet to be released)¶

Future release notes will be placed here

Development¶

CI: Check for runtime dependencies (#574)

Kudos @ppentchev for inspiration on the command (comment).

libtmux 0.44.2 (2025-02-17)¶

Bug fix¶

Fix typing_extensions issue by wrapping it in TYPE_CHECKING, continuation of #564, via #572.

Development¶

Improved test organization and coverage in test_common.py (#570):
- Consolidated version-related tests into parametrized fixtures using NamedTuples
- Added comprehensive test cases for various version formats (master, next, OpenBSD, dev, rc)
- Improved test readability with clear test IDs and logical grouping
- Consistent use of pytest parametrize convention across test suite
Fix broken test for test_window_rename (#570)

libtmux 0.44.1 (2025-02-17)¶

Packaging¶

Types: Only import typing_extensions when necessary, via #563, @ppentchev!

libtmux 0.44.0 (2025-02-16)¶

New Features¶

Context Managers support (#566)¶

Added context manager support for all major object types:

Server: Automatically kills the server when exiting the context
Session: Automatically kills the session when exiting the context
Window: Automatically kills the window when exiting the context
Pane: Automatically kills the pane when exiting the context

Example usage:

with Server() as server:
    with server.new_session() as session:
        with session.new_window() as window:
            with window.split() as pane:
                pane.send_keys('echo "Hello"')
                # Do work with the pane
                # Everything is cleaned up automatically when exiting contexts

This makes it easier to write clean, safe code that properly cleans up tmux resources.

libtmux 0.43.0 (2025-02-15)¶

New Features¶

Server Initialization Callbacks¶

Server now accepts 2 new optional params, socket_name_factory and on_init callbacks (#565):

socket_name_factory: Callable that generates unique socket names for new servers
on_init: Callback that runs after server initialization
Useful for creating multiple servers with unique names and tracking server instances
Socket name factory is tried after socket_name, maintaining backward compatibility

New test fixture: `TestServer`¶

Add TestServer pytest fixture for creating temporary tmux servers (#565):

Creates servers with unique socket names that clean up after themselves
Useful for testing interactions between multiple tmux servers
Includes comprehensive test coverage and documentation
Available in doctest namespace

Documentation¶

Fix links to the “Topics” section
More docs for “Traversal” Topic (#567)

Breaking changes¶

Detached / unselected by default (#523)¶

To ensure consistency and principle of least surprise, keep these set to not use -a unless explicitly specified.

Breaking: Session.new_window() + Window.split_window() no longer attaches by default.

0.28.0 and greater: Defaults to attach=False.
0.27.1 and below: Defaults to attach=True.

To keep the old behavior in 0.28.0 and beyond, pass attach=True explicitly.

Improved resizing (#523)¶

Breaking: Pane.resize_pane() renamed to Pane.resize() (#523)

This convention will be more consistent with Window.resize().
Breaking: Pane.resize()’s params changed (#523)
- No longer accepts -U, -D, -L, -R directly, instead accepts ResizeAdjustmentDirection).
Pane.resize():
- Accept adjustments via adjustment_direction w/ ResizeAdjustmentDirection + adjustment.
- Learned to accept manual height and / or width (columns/rows or percentage)
- Zoom (and unzoom)
Window.resize(): Newly added

Tip: If Pane.resize() was not taking affect <= 0.27.1, try to resize with Window.resize() first.

Fixes¶

Window.refresh() and Pane.refresh(): Refresh more underlying state (#523)
Obj._refresh(): Allow passing args (#523)

e.g. -a (all) to list-panes and list-windows
Server.panes: Fix listing of panes (#523)

Would list only panes in attached session, rather than all in a server.

Improvement¶

Pane, Window: Improve parsing of option values that return numbers (#520)
Obj._refresh: Allow passing list_extra_args to ensure list-windows and list-panes can return more than the target (#523)

Per Poetry’s docs on managing dependencies and poetry check, we had it wrong: Instead of using extras, we should create these:
```
[tool.poetry.group.group-name.dependencies]
dev-dependency = "1.0.0"
```
Which we now do.

Development¶

libtmux 0.16.1 (2022-12-12)¶

Fixes¶

Remove reliance on packaging.version.Version (#461)

This is too critical of a package to pin a dependency as it may interfere with other packages the user relies on. In addition, libtmux doesn’t need strict compatibility with packaging.

libtmux 0.16.0 (2022-12-10)¶

Breaking changes¶

Fix distutils warning, vendorize LegacyVersion (#351)

Removal of reliancy on distutils.version.LooseVersion, which does not support tmux(1) versions like 3.1a.

Fixes warning:

DeprecationWarning: distutils Version classes are deprecated. Use packaging.version instead.

The temporary workaround, before 0.16.0 (assuming setup.cfg):
```
[tool:pytest]
filterwarnings =
    ignore:.* Use packaging.version.*:DeprecationWarning::
    ignore:The frontend.Option(Parser)? class.*:DeprecationWarning::
```

Server.new_session() works without session_name, #400 fixes #399

This still passed None to the session name, this was fixed in v0.14.2.

libtmux 0.14.0 (2022-08-05)¶

Breaking changes¶

Pane.send_keys(): suppress_history default value changed from True to False, #395

Tests and docs¶

Initial doctests examples stubbed out #394
Fix bug in temp_window() context manager, #394
Pytest configuration conftest.py moved to libtmux/conftest.py, so doctest can detect the fixtures #394

libtmux 0.13.0 (2022-08-05)¶

What’s new¶

Improved typings

Now mypy --strict compliant (#383)

Smaller touchups from #392

Breaking changes¶

Deprecated individual item lookups (#390)

Removed key lookups from libtmux.common.EnvironmentMixin.show_environment()

Only EnvironmentMixin.show_environment() (without an argument) exists, and it still returns a dict.

Add key lookups via libtmux.common.EnvironmentMixin.getenv()

# Before
server.show_environment('DISPLAY')

# After
server.getenv('DISPLAY')

# Before
session.show_environment('DISPLAY')

# After
session.getenv('DISPLAY')

Removed key lookups from Session.show_options()

session.show_options()  # still returns dict, without an argument

# Old
session.show_options('DISPLAY')

# Now
session.show_option('DISPLAY')

Removed key lookups from Window.show_window_options()

window.show_window_options()  # still returns dict, without an argument

# Old
window.show_window_options('DISPLAY')

# Now
window.show_window_option('DISPLAY')

Remove libtmux.test.retry(), deprecated since 0.12.x (#393)

Development¶

Fix incorrect function name findWhere() (#391)

libtmux 0.12.0 (2022-07-13)¶

Compatibility¶

Brought back python 3.7 and 3.8 support (#375)
Support for tmux 3.3a
- Add to CI
- Bump TMUX_MAX_VERSION from 2.4 -> 3.3
  
  2.4 to 3.3a already worked, this is just the constant being updated.

Development¶

Remove tox and tox-poetry-installer

This created issues with running poetry while inside the virtualenv.
Typings: Core relations, e.g. Pane.window, Pane.session, Pane.server, Window.server #385

Documentation¶

Renewed logo
Try out sphinx-autoapi for its table of contents generation (#367)
Break up API documentations for utilities, exception, and test helpers and remove duplicate docs from API page. Server, session, window, and pane docs are in the Reference section now.

Testing¶

retry(): Add deprecation warning. This will be removed in 0.13.x (#368, #372)
New function retry_until(): Polls a callback function for a set period of time until it returns True or times out. By default it will raise libtmux.exc.WaitTimeout, with raises=False it will return False. Thank you @categulario! (#368, #372)

#384 Chore: Use absolute modules rather than root-level to avoid cyclic imports.

# Bad / Old
from libtmux import Server

# Good / New
from libtmux.server import Server

Internals¶

#382 [mypy] support added:
- Basic mypy tests now pass

libtmux 0.11.0 (2022-03-10)¶

Compatibility¶

Python 3.7 and 3.8 returns in 0.12.0

~~Final python 3.7 and 3.8 release~~

~~Fixes and security updates will go to v0.11.x~~
Internal: Use new separator to split tmux(1) formatting information (#289, #343)

The separator is configurable via LIBTMUX_TMUX_FORMAT_SEPARATOR. If you ever have compatibility issues in the future let us know which default works best across versions.
