## libtmux 0.35.1 (2024-03-23)

### Bug fix

- {attr}`Server.attached_sessions` fix for when multiple clients attached, thank you @patrislav1 (#537)

  - #538 fix to `QueryList`.

## libtmux 0.35.0 (2024-03-17)

### Breaking changes

- Eliminate redundant targets / `window_index`'s across codebase (#536).

## libtmux 0.34.0 (2024-03-17)

### Breaking changes

#### Command target change (#535)

Commands: All `cmd()` methods using custom or overridden targets must use the keyword argument
`target`. This avoids entanglement with inner shell values that include `-t` for
other purposes. These methods include:

- {meth}`Server.cmd()`
- {meth}`Session.cmd()`
- {meth}`Window.cmd()`
- {meth}`Pane.cmd()`

## libtmux 0.33.0 (2024-03-17)

### Breaking changes

#### Improved new sessions (#532)

- `Session.new_window()`:

  - Learned `direction`, via {class}`~libtmux.constants.WindowDirection`).
  - [PEP 3102] keyword-only arguments after window name (#534).

- Added {meth}`Window.new_window()` shorthand to create window based on that
  window's position.

[PEP 3102]: https://www.python.org/dev/peps/pep-3102/

#### Improved window splitting (#532)

- `Window.split_window()` to {meth}`Window.split()`

  - Deprecate `Window.split_window()`

- `Pane.split_window()` to {meth}`Pane.split()`

  - Deprecate `Pane.split_window()`
  - Learned `direction`, via {class}`~libtmux.constants.PaneDirection`).

    - Deprecate `vertical` and `horizontal` in favor of `direction`.

  - Learned `zoom`

#### Tweak: Pane position (#532)

It's now possible to retrieve the position of a pane in a window via a
`bool` helper::

- {attr}`Pane.at_left`
- {attr}`Pane.at_right`
- {attr}`Pane.at_bottom`
- {attr}`Pane.at_right`

### Development

- poetry: 1.7.1 -> 1.8.1

  See also: https://github.com/python-poetry/poetry/blob/1.8.1/CHANGELOG.md

## libtmux 0.32.0 (2024-03-01)

### Development

- ruff 0.2.2 -> 0.3.0

## libtmux 0.31.0 (2024-02-17)

### Cleanups (#527)

- Streamline `{Server,Session,Window,Pane}.cmd()`, across all usages to:
  - Use `cmd: str` as first positional
  - Removed unused keyword arguments `**kwargs`

### Renamings (#527)

- `Session.attached_window` renamed to {meth}`Session.active_window`

  - `Session.attached_window` deprecated

- `Session.attached_pane` renamed to {meth}`Session.active_pane`

  - `Session.attached_pane` deprecated

- `Window.attached_pane` renamed to {meth}`Window.active_pane`

  - `Window.attached_pane` deprecated

### Improvements (#527)

- `Server.attached_windows` now uses `QueryList`'s `.filter()`

### Documentation (#527)

- Document `.cmd` in README and quickstart
- Add doctests and improve docstrings to `cmd()` methods across:
  - {meth}`Server.cmd()`
  - {meth}`Session.cmd()`
  - {meth}`Window.cmd()`
  - {meth}`Pane.cmd()`

### Post-release: v0.31.0post0 (2024-02-17)

- Documentation updates

## libtmux 0.30.2 (2024-02-16)

### Development

- Updated `TMUX_MAX_VERSION` from 3.3 to 3.4

## libtmux 0.30.1 (2024-02-16)

### Fixes

- Adjusted pytest plugin and test module: Updated to use renamed methods from
  version 0.30.0.

## libtmux 0.30.0 (2024-02-16)

### Additions

- Introduced {meth}`Pane.kill()` method

### Modifications

- `Window.select_window()` renamed to {meth}`Window.select()`
  - Deprecated `Window.select_window()`
- `Pane.select_pane()` renamed to {meth}`Pane.select()`
  - Deprecated `Pane.pane_select()`
- `Session.attach_session()` renamed to {meth}`Session.attach()`
  - Deprecated `Session.attach_session()`
- `Server.kill_server()` renamed to {meth}`Server.kill()`
  - Deprecated `Server.kill_server()`
- `Session.kill_session()` renamed to {meth}`Session.kill()`
  - Deprecated `Session.kill_session()`

  - Deprecated `Window.kill_window()`

### Enhancements

- {meth}`Server.new_session()`: Support environment variables
- {meth}`Window.split_window()`: Support `size` via `-l`

  Supports columns/rows (`size=10`) and percentage (`size='10%'`)

## libtmux 0.29.0 (2024-02-16)

#### Fixes

- Use {exc}`DeprecationWarning` for APIs set to be deprecated (#526)

#### Testing

- pytest: Ignore {exc}`DeprecationWarning` by default (#526)

## libtmux 0.28.1 (2024-02-15)

_Maintenance only, no bug fixes or new features_

#### Testing

- CI: Bump actions to node 20+ versions

#### 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)
- ci: Add tmux 3.4 to test matrix (#909)

## libtmux 0.27.1 (2024-02-07)

### Packaging

- Include `MIGRATION` in source distribution tarball (#517, for #508)

## libtmux 0.27.0 (2024-02-07)

### Improvement

  - This improves the annotations in descendant objects such as:

    - `Server.sessions`
    - `Session.windows`
    - `Window.panes`

  - Bolster tests (ported from `libvcs`): doctests and pytests

## libtmux 0.26.0 (2024-02-06)

### Breaking changes

- `get_by_id()` (already deprecated) keyword argument renamed from `id` to
  `Server.get_by_id(session_id)`, `Session.get_by_id(window_id)`, and `Window.get_by_id(pane_id)` (#514)

### Documentation

- Various docstring fixes and tweaks (#514)

### Development

- Strengthen linting (#514)

  - Add flake8-commas (COM)

    - https://docs.astral.sh/ruff/rules/#flake8-commas-com

  See also: https://github.com/python-poetry/poetry/blob/1.7.0/CHANGELOG.md

- Packaging (poetry): Fix development dependencies

  Per [Poetry's docs on managing dependencies] and `poetry check`, we had it wrong: Instead of using extras, we should create these:

  ```toml
  [tool.poetry.group.group-name.dependencies]
  dev-dependency = "1.0.0"
  ```

  Which we now do.

  [Poetry's docs on managing dependencies]: https://python-poetry.org/docs/master/managing-dependencies/

### Development

- Move formatting from `black` to [`ruff format`] (#506)

  This retains the same formatting style of `black` while eliminating a

  [typos-cli]: https://github.com/crate-ci/typos

- ruff: Remove ERA / `eradicate` plugin

  This rule had too many false positives to trust. Other ruff rules have been beneficial.

## libtmux 0.23.0 (2023-08-20)

_Maintenance only, no bug fixes or new features_

### Development

- Code quality improved via [ruff] rules (#488)

  This includes fixes made by hand, and with ruff's automated fixes. Despite
  selecting additional rules, which include import sorting, ruff runs nearly
  instantaneously when checking the whole codebase.

### Post-release: v0.23.0post0 (2023-08-20)

- Fixes code comments cleaned up by `ruff`, but missed in QA. In the future,
  even when using an automated tool, we will review more thoroughly.

### Development

- Add back `black` for formatting

  This is still necessary to accompany `ruff`, until it replaces black.

## libtmux 0.22.0 (2023-05-27)

_Maintenance only, no bug fixes or new features_

### Internal improvements

- Move formatting, import sorting, and linting to [ruff].

  This rust-based checker has dramatically improved performance. Linting and
  formatting can be done almost instantly.

  This change replaces black, isort, flake8 and flake8 plugins.

- poetry: 1.4.0 -> 1.5.0

  See also: https://github.com/python-poetry/poetry/releases/tag/1.5.0

  ```

  New `__repr__` (0.18+):

  ```python
  Server(socket_name=test)
  ```

## libtmux 0.17.0 (2022-12-26)

### Breaking changes (#426)

- Finding objects / relations

  - 0.16 and below: `session._windows()`, `session.list_windows()`, etc.

    0.17 and after: {attr}`session.windows <libtmux.Session.windows>`

  - 0.16 and below: `session.find_where({'window_name': my_window})`

    0.17 and after: {meth}`session.windows.get(window_name=my_window, default=None) <libtmux.Session.windows>`

    - If not found and not `default`, raises {exc}`~libtmux._internal.query_list.ObjectDoesNotExist`
    - If multiple objects found, raises {exc}`~libtmux._internal.query_list.MultipleObjectsReturned`

  - 0.16 and below: `session.where({'window_name': my_window})`

    0.17 and after: {meth}`session.windows.filter(window_name=my_window) <libtmux.Session.windows>`

- Accessing attributes

  - 0.16 and below: `window['id']`

    0.17 and after: `window.id`

  - 0.16 and below: `window.get('id')`

    0.17 and after: `window.id`

  - 0.16 and below: `window.get('id', None)`

    0.17 and after: `getattr(window, 'id', None)`

### New features

### Internal

- Remove unused `sphinx-click` development dependency

## 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_):

  ```ini
  [tool:pytest]
  filterwarnings =
      ignore:.* Use packaging.version.*:DeprecationWarning::
      ignore:The frontend.Option(Parser)? class.*:DeprecationWarning::
  ```

- Added a [pytest plugin](https://libtmux.git-pull.com/pytest-plugin.html), #411.

### Breaking changes

- Remove `common.which()` in favor of {func}`shutil.which`, Credit:
  @rocksandska, via #407
- Fixes #402: {func}`common.tmux_cmd` will only strip _trailing_ empty lines. Before this change,
  all empty lines were filtered out. This will lead to a more accurate behavior when using
  {meth}`Pane.capture_pane`. Credit: @rockandska, via #405.
- Source files for `libtmux` modules moved to `src/`, via #414.

### Development

- Add [flake8-bugbear](https://github.com/PyCQA/flake8-bugbear) (#408)
- Add [flake8-comprehensions](https://github.com/adamchainz/flake8-comprehensions) (#409)

### Tests

- Test doctests in documentation via
  [pytest-doctest-docutils](https://gp-libs.git-pull.com/doctest/pytest.html) (#410)

### Documentation

- Examples updated for correctness, #412 (cherry-picked from #410)
- Render changelog in [linkify_issues](https://gp-libs.git-pull.com/linkify_issues/) (#410)
- Fix Table of contents rendering with sphinx autodoc with
  [sphinx_toctree_autodoc_fix](https://gp-libs.git-pull.com/sphinx_toctree_autodoc_fix/) (#410)

## libtmux 0.14.2 (2022-08-17)

### Fixes

- {meth}`Server.new_session` _really_ works without `session_name`, #401 fixes
  #399. Improved tests and doctests added.

## libtmux 0.14.1 (2022-08-17)

### Fixes

- {meth}`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

- {meth}`Pane.send_keys`: `suppress_history` default value changed from `True` to
  `False`, #395

### Tests and docs

- Initial [doctests] examples stubbed out #394

  [doctests]: https://docs.python.org/3/library/doctest.html

- 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

  [`mypy --strict`]: https://mypy.readthedocs.io/en/stable/command_line.html#cmdoption-mypy-strict

### Breaking changes

- Deprecated individual item lookups (#390)

  - Removed key lookups from {meth}`libtmux.common.EnvironmentMixin.show_environment`

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

  - Add key lookups via {meth}`libtmux.common.EnvironmentMixin.getenv`

    ```python
    # Before
    server.show_environment('DISPLAY')

    # After
    server.getenv('DISPLAY')

    # Before
    session.show_environment('DISPLAY')

    # After
    session.getenv('DISPLAY')
    ```

  - Removed key lookups from {meth}`Session.show_options`

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

    # Old
    session.show_options('DISPLAY')

    # Now
    session.show_option('DISPLAY')
    ```

  - Removed key lookups from {meth}`Window.show_window_options`

    ```python
    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 {exc}`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.

  ```python
  # 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`](https://github.com/tmux-python/libtmux/tree/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.
