libtmux 0.56.x (Yet to be released)

Notes on the upcoming release will go here.

libtmux 0.55.0 (2026-03-07)

What's new

Pane.set_title() (#636)

New {meth}~libtmux.Pane.set_title method wraps select-pane -T, and {attr}~libtmux.Pane.title provides a short alias for {attr}~libtmux.Pane.pane_title:

pane.set_title("my-worker")
pane.pane_title
# 'my-worker'
pane.title
# 'my-worker'

The pane_title format variable is now included in libtmux's format queries (it was previously excluded).

Configurable tmux binary path (#636)

{class}~libtmux.Server now accepts a tmux_bin parameter to use an alternative tmux binary (e.g. wemux, byobu, or a custom build):

server = Server(socket_name="myserver", tmux_bin="/usr/local/bin/tmux-next")

The path is threaded through {meth}~libtmux.Server.cmd, {meth}~libtmux.Server.raise_if_dead, {func}~libtmux.neo.fetch_objs, all version-check functions ({func}~libtmux.common.has_version, {func}~libtmux.common.has_gte_version, etc.), and hook scope guards in {class}~libtmux.hooks.HooksMixin. All child objects (Session, Window, Pane) inherit it automatically. Falls back to shutil.which("tmux") at execution time when not set.

Pre-execution command logging (#636)

{class}~libtmux.common.tmux_cmd now logs the full command line at DEBUG level before execution, complementing the existing post-execution stdout logging. This enables diagnostic output and is a prerequisite for a future dry-run mode.

Bug fixes

TmuxCommandNotFound raised for invalid tmux_bin path (#636)

Previously, passing a non-existent binary path raised a raw FileNotFoundError from subprocess. It now raises {exc}~libtmux.exc.TmuxCommandNotFound consistently, in both tmux_cmd and raise_if_dead.

libtmux 0.54.0 (2026-03-07)

What's new

Structured lifecycle logging across Server, Session, Window, and Pane (#637)

All lifecycle operations (create, kill, rename, split) now emit INFO-level log records with structured extra context. Every log call includes scalar keys such as tmux_subcommand, tmux_session, tmux_window, tmux_pane, and tmux_target for filtering in log aggregators and test assertions via caplog.records.

  • Add NullHandler to library __init__.py per Python logging best practices
  • Add DEBUG-level structured logs for tmux_cmd execution with isEnabledFor guards
  • Replace f-string log formatting with lazy %s formatting throughout
  • Replace traceback.print_stack() calls with proper logger.debug(exc_info=True)
  • Replace logger.exception() in options parsing with logger.warning() and tmux_option_key context
  • Remove unused logger definitions from modules that don't log

Bug fixes

Window.rename_window() now raises on failure instead of silently swallowing (#637)

Previously rename_window() caught all exceptions and logged them, masking tmux errors. It now propagates the error, consistent with all other command methods.

Server.kill() captures stderr and handles "no server running" gracefully (#637)

Server.kill() previously discarded the tmux return value. It now checks stderr, raises on unexpected errors, and silently returns for expected conditions ("no server running", "error connecting to").

Server.new_session() checks kill-session stderr (#637)

When kill_session=True and the existing session kill fails, new_session() now raises LibTmuxException with the stderr instead of proceeding silently.

libtmux 0.53.1 (2026-02-18)

Bug fixes

Fix race condition in new_session() (#625)

Fixed {exc}~libtmux.exc.TmuxObjectDoesNotExist raised by {meth}~libtmux.Server.new_session in some environments (e.g. PyInstaller-bundled binaries, Python 3.13+, Docker containers).

Previously, new_session() ran tmux new-session -P -F#{session_id} to create the session, then immediately issued a separate list-sessions query to hydrate the {class}~libtmux.Session object. In certain environments the session was not yet visible to list-sessions, causing a spurious failure.

The fix expands the -F format string to include all session fields and parses the new-session -P output directly into the returned Session, eliminating the follow-up query entirely. This is also one fewer subprocess call per session creation.

Closes: #624. Thank you @neubig!

Development

Makefile -> Justfile (#617)

  • Migrate from Makefile to justfile for running development tasks
  • Update documentation to reference just commands

Documentation

Move documentation deployment to GitHub OIDC and AWS CLI.

libtmux 0.53.0 (2025-12-14)

Breaking changes

Session.attach() no longer calls refresh() (#616)

{meth}~libtmux.Session.attach previously called {meth}~libtmux.neo.Obj.refresh after the attach-session command returned. This was semantically incorrect since attach-session is a blocking interactive command where session state can change arbitrarily during attachment.

This was never strictly defined behavior as libtmux abstracts tmux internals away. Code that relied on the session object being refreshed after attach() should explicitly call session.refresh() if needed.

Bug fixes

Session.attach() no longer fails if session killed during attachment (#616)

Fixed an issue where {meth}~libtmux.Session.attach would raise {exc}~libtmux.exc.TmuxObjectDoesNotExist when a user killed the session while attached (e.g., closing all windows) and then detached.

libtmux 0.52.1 (2025-12-07)

CI

Migrate to PyPI Trusted Publisher (#615)

PyPI publishing now uses OIDC-based Trusted Publisher instead of API tokens. This improves security and enables package attestations for supply chain verification.

libtmux 0.52.0 (2025-12-07)

Pane.capture_pane() enhanced (#614)

The {meth}~libtmux.pane.Pane.capture_pane method now supports 5 new parameters that expose additional tmux capture-pane flags:

Parameter tmux Flag Description
escape_sequences -e Include ANSI escape sequences (colors, attributes)
escape_non_printable -C Escape non-printable chars as octal \xxx
join_wrapped -J Join wrapped lines back together
preserve_trailing -N Preserve trailing spaces at line ends
trim_trailing -T Trim trailing empty positions (tmux 3.4+)

Capturing colored output:

# Capture with ANSI escape sequences preserved
pane.send_keys('printf "\\033[31mRED\\033[0m"', enter=True)
output = pane.capture_pane(escape_sequences=True)
# Output contains: '\x1b[31mRED\x1b[0m'

Joining wrapped lines:

# Long lines that wrap are joined back together
output = pane.capture_pane(join_wrapped=True)

Version compatibility:

The trim_trailing parameter requires tmux 3.4+. If used with an older version, a warning is issued and the flag is ignored. All other parameters work with libtmux's minimum supported version (tmux 3.2a).

libtmux 0.51.0 (2025-12-06)

Breaking changes

APIs deprecated (#611)

Legacy API methods (deprecated in 0.16-0.33) now raise {exc}~libtmux.exc.DeprecatedError (hard error) instead of emitting {class}DeprecationWarning.

libtmux 0.50.1 (2025-12-06)

Documentation (#612)

  • Normalize docs headings and Sphinx module directives to fix anchor and index generation issues.
  • Tweak Sphinx type-hints configuration to avoid RST indentation conflicts and suppress forward-reference warnings.
  • Refresh docstrings and cross-references (pane/window APIs, environment helpers, pytest plugin) for clearer return types and stable anchors.
  • Fix incorrect return type annotations for capture_pane() and display_message() methods (changed from str | list[str] to list[str] - the methods always return a list).

libtmux 0.50.0 (2025-11-30)

Overview

libtmux 0.50 brings a major enhancement to option and hook management. The new {class}~options.OptionsMixin and {class}~hooks.HooksMixin classes provide a unified, typed API for managing tmux options and hooks across all object types.

Highlights:

  • Unified Options API: New show_option(), show_options(), set_option(), and unset_option() methods available on Server, Session, Window, and Pane.
  • Hook Management: Full programmatic control over tmux hooks with support for indexed hook arrays and bulk operations.
  • SparseArray: New internal data structure for handling tmux's sparse indexed arrays (e.g., command-alias[0], command-alias[99]).
  • tmux 3.2+ baseline: Removed support for tmux versions below 3.2a, enabling cleaner code and full hook/option feature support.

What's New

Unified Options API (#516)

All tmux objects now share a consistent options interface through {class}~options.OptionsMixin:

import libtmux

server = libtmux.Server()
session = server.sessions[0]
window = session.windows[0]
pane = window.panes[0]

# Get all options as a structured dict
session.show_options()
# {'activity-action': 'other', 'base-index': 0, ...}

# Get a single option value
session.show_option('base-index')
# 0

# Set an option
window.set_option('automatic-rename', True)

# Unset an option (revert to default)
window.unset_option('automatic-rename')

New methods on Server, Session, Window, and Pane:

Method Description
show_options() Get all options as a structured dict
show_option(name) Get a single option value
set_option(name, value) Set an option
unset_option(name) Unset/remove an option

New parameters for set_option():

Parameter tmux flag Description
_format -F Expand format strings in value
unset -u Unset the option
global_ -g Set as global option
unset_panes -U Also unset in child panes
prevent_overwrite -o Don't overwrite if exists
suppress_warnings -q Suppress warnings
append -a Append to existing value

Hook Management (#516)

New {class}~hooks.HooksMixin provides programmatic control over tmux hooks:

session = server.sessions[0]

# Set a hook
session.set_hook('session-renamed', 'display-message "Renamed!"')

# Get hook value
session.show_hook('session-renamed')
# 'display-message "Renamed!"'

# Get all hooks
session.show_hooks()
# {'session-renamed': 'display-message "Renamed!"'}

# Remove a hook
session.unset_hook('session-renamed')

Indexed hooks and bulk operations:

tmux hooks support multiple values via indices (e.g., session-renamed[0], session-renamed[1]). The bulk operations API makes this easy:

# Set multiple hooks at once
session.set_hooks('session-renamed', {
    0: 'display-message "Hook 0"',
    1: 'display-message "Hook 1"',
    5: 'run-shell "echo hook 5"',
})

Hook methods available on Server, Session, Window, and Pane:

Method Description
set_hook(hook, value) Set a hook
show_hook(hook) Get hook value (returns SparseArray for indexed hooks)
show_hooks() Get all hooks
unset_hook(hook) Remove a hook
run_hook(hook) Run a hook immediately
set_hooks(hook, values) Set multiple indexed hooks at once

SparseArray for Indexed Options (#516)

tmux uses sparse indexed arrays for options like command-alias[0], command-alias[99], terminal-features[0]. Python lists can't represent gaps in indices, so libtmux introduces {class}~_internal.sparse_array.SparseArray:

>>> from libtmux._internal.sparse_array import SparseArray

>>> arr: SparseArray[str] = SparseArray()
>>> arr.add(0, "first")
>>> arr.add(99, "ninety-ninth")  # Gap in indices preserved!
>>> arr[0]
'first'
>>> arr[99]
'ninety-ninth'
>>> list(arr.keys())
[0, 99]
>>> list(arr.iter_values())  # Values in index order
['first', 'ninety-ninth']

New Constants (#516)

  • {class}~constants.OptionScope enum: Server, Session, Window, Pane
  • OPTION_SCOPE_FLAG_MAP: Maps scope to tmux flags (-s, -w, -p)
  • HOOK_SCOPE_FLAG_MAP: Maps scope to hook flags

Breaking changes

Deprecated Window methods (#516)

The following methods are deprecated and will be removed in a future release:

Deprecated Replacement
Window.set_window_option() Window.set_option()
Window.show_window_option() Window.show_option()
Window.show_window_options() Window.show_options()

The old methods will emit a {class}DeprecationWarning when called:

window.set_window_option('automatic-rename', 'on')
# DeprecationWarning: Window.set_window_option() is deprecated

# Use the new method instead:
window.set_option('automatic-rename', True)

tmux Version Compatibility

Feature Minimum tmux
All options/hooks features 3.2+
Window/Pane hook scopes (-w, -p) 3.2+
client-active, window-resized hooks 3.3+
pane-title-changed hook 3.5+

libtmux 0.49.0 (2025-11-29)

Breaking Changes

tmux 1.8 to 3.1c support removed (#608)

Support for tmux versions below 3.2a has been removed. This completes the deprecation announced in v0.48.0.

  • Minimum tmux version is now 3.2a (TMUX_MIN_VERSION)
  • Removed TMUX_SOFT_MIN_VERSION constant and deprecation warning system
  • Removed version guards throughout the codebase
  • For users on older tmux, use libtmux v0.48.x

libtmux 0.48.0 (2025-11-28)

Breaking Changes

Minimum tmux version bumped to 3.2+ (606)

tmux versions below 3.2a are now deprecated. libtmux 0.48.0 will be the last version to support tmux below 3.2. This is to ensure support for hooks, options, and newer tmux features.

A FutureWarning will be emitted on first use. Support for these versions will be removed in a future release. Set LIBTMUX_SUPPRESS_VERSION_WARNING=1 to suppress the warning.

Internal

  • Added TMUX_SOFT_MIN_VERSION constant (3.2a) for deprecation threshold (#606)

What's new

tmux 3.6 support (#607)

Added tmux 3.6 to test grid and TMUX_MAX_VERSION 3.4 -> 3.6.

libtmux 0.47.0 (2025-11-01)

    • Pane.split and Pane.split_window: Accept PathLike objects for pane start directory
    • Window.split and Window.split_window: Accept PathLike objects for pane start directory
    • Enables pathlib.Path objects alongside strings for all start directory parameters
    • Includes comprehensive tests for all parameter types (None, empty string, string paths, PathLike objects)

    Thank you @Data5tream for the initial commit in #596!

libtmux 0.46.1 (2025-03-16)

libtmux 0.46.0 (2025-02-25)

Breaking

Imports removed from libtmux.test (#580)

Root-level of imports from libtmux.test are no longer possible.

# Before 0.46.0
from libtmux.test import namer
# From 0.46.0 onward
from libtmux.test.named import namer

Same thing with constants:

# Before 0.46.0
from libtmux.test import (
  RETRY_INTERVAL_SECONDS,
  RETRY_TIMEOUT_SECONDS,
  TEST_SESSION_PREFIX
)
# From 0.46.0 onward
from libtmux.test.constants import (
  RETRY_INTERVAL_SECONDS,
  RETRY_TIMEOUT_SECONDS,
  TEST_SESSION_PREFIX
)

Development

Test helpers: Increased coverage (#580)

Several improvements to the test helper modules:

  • Enhanced EnvironmentVarGuard in libtmux.test.environment to better handle variable cleanup
  • Added comprehensive test suites for test constants and environment utilities
  • Improved docstrings and examples in libtmux.test.random with test coverage annotations
  • Fixed potential issues with environment variable handling during tests
  • Added proper coverage markers to exclude type checking blocks from coverage reports

libtmux 0.45.0 (2025-02-23)

Breaking Changes

Test helpers: Refactor

Test helper functionality has been split into focused modules (#578):

  • libtmux.test module split into:
    • libtmux.test.constants: Test-related constants (TEST_SESSION_PREFIX, etc.)
    • libtmux.test.environment: Environment variable mocking
    • libtmux.test.random: Random string generation utilities
    • libtmux.test.temporary: Temporary session/window management

Breaking: Import paths have changed. Update imports:

# Old (0.44.x and earlier)
from libtmux.test import (
    TEST_SESSION_PREFIX,
    get_test_session_name,
    get_test_window_name,
    namer,
    temp_session,
    temp_window,
    EnvironmentVarGuard,
)
# New (0.45.0+)
from libtmux.test.constants import TEST_SESSION_PREFIX
from libtmux.test.environment import EnvironmentVarGuard
from libtmux.test.random import get_test_session_name, get_test_window_name, namer
from libtmux.test.temporary import temp_session, temp_window

  • 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

Documentation

  • Refine docs and add migration for v0.28.0

libtmux 0.28.0 (2024-02-14)

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: {meth}Session.new_window() + {meth}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 {meth}Pane.resize() (#523)

    This convention will be more consistent with {meth}Window.resize().

  • Breaking: {meth}Pane.resize()'s params changed (#523)

    • No longer accepts -U, -D, -L, -R directly, instead accepts {class}~libtmux.constants.ResizeAdjustmentDirection).

  • {meth}Pane.resize():

    • Accept adjustments via adjustment_direction w/ {class}~libtmux.constants.ResizeAdjustmentDirection + adjustment.

    • Learned to accept manual height and / or width (columns/rows or percentage)

    • Zoom (and unzoom)

  • {meth}Window.resize(): Newly added

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

Fixes

  • {meth}Window.refresh() and {meth}Pane.refresh(): Refresh more underlying state (#523)

  • {meth}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)

Tests

  • pytest: Fix usefixture warning (#519)
