## tmuxp 1.48.0 (unreleased)

<!-- Maintainers, insert changes / features for the next release here -->

### Development

- Code quality: Use f-strings in more places (#931)

  via [ruff 0.4.2](https://github.com/astral-sh/ruff/blob/v0.4.2/CHANGELOG.md).

## tmuxp 1.47.0 (2024-04-21)

_Maintenance only, no bug fixes or new features_

### Developmental

- libtmux: 0.36.0 -> 0.37.0 (#929)

  Internal improvements to test suite (pytest-xdist and relaxing `retry_until()` tests)

## tmuxp 1.46.0 (2024-04-12)

### Breaking change

#### Workspace builder now detects terminal size (#926)

Dimensions used by workspace builder now use {py:func}`shutil.get_terminal_size()`.

In conjunction with `main-pane-height: 67%`, for instance, this will render a
proportional layout:

```yaml
session_name: my session
windows:
- window_name: example with percentage
  focus: True
  layout: main-horizontal
  options:
    main-pane-height: 67%
  panes:
  - focus: true
  - pane 
```

To use old behavior, set `TMUXP_DETECT_TERMINAL_SIZE=0` in your terminal
environment and file an issue on the tracker.

### Documentation

- Automatically linkify links that were previously only text.

### Development

- Another `ruff` linting pass, this time with ruff 0.3.7 (#928)
- poetry: 1.8.1 -> 1.8.2

  See also: https://github.com/python-poetry/poetry/blob/1.8.2/CHANGELOG.md

## tmuxp 1.45.0 (2024-03-24)

_Maintenance only, no bug fixes or new features_

### Development

- Aggressive automated lint fixes via `ruff` (#922)

  via ruff v0.3.4, all automated lint fixes, including unsafe and previews were applied:

  ```sh
  ruff check --select ALL . --fix --unsafe-fixes --preview --show-fixes; ruff format .
  ```

  Branches were treated with:

  ```sh
  git rebase \
      --strategy-option=theirs \
      --exec 'poetry run ruff check --select ALL . --fix --unsafe-fixes --preview --show-fixes; poetry run ruff format .; git add src tests; git commit --amend --no-edit' \
      origin/master

  Allow to configure window and pane specific environment variables

  Having a setup like:

  ```yaml
  session_name: env-demo
  environment:
    DATABASE_URL: "sqlite3:///default.db"
  windows:
    - window_name: dev
      environment:
        DATABASE_URL: "sqlite3:///dev-1.db"
      panes:
        - pane
        - environment:
            DATABASE_URL: "sqlite3:///dev-2.db"
  ```

  will result in a window with two panes. In the first pane `$DATABASE_URL` is
  `sqlite3:///dev-1.db`, while in the second pane it is `sqlite3://dev-2.db`.
  Any freshly created window gets `sqlite3:///default.db` as this is what was
  defined for the session.

  start_directory: "~"
  options:
    default-size: 999x999
  windows:
    - window_name: my window name
      layout: main-horizontal
      options:
        main-pane-height: 30
      panes:
        - shell_command: top
        - shell_command: top

### What's new

- #747: Skip execution via `enter: false`

  See {ref}`enter`.

  :::{note}

  _Experimental setting_: behavior and api is subject to change until stable.

  :::

  ```yaml
  session_name: Should not execute
  windows:
    - panes:
        - shell_command:
            - echo "this sends"
            - cmd: echo "___$((1 + 3))___"
              enter: false
            # pane-wide skip
        - shell_command:
            - echo "___$((1 + 3))___"
          enter: false
  ```

- #750: Pause execution via `sleep_before: [int]` and `sleep_after: [int]`

  See {ref}`sleep`.

  :::{note}

  _Experimental setting_: behavior and api is subject to change until stable.

  :::

  ```yaml
  session_name: Pause / skip command execution (command-level)
  windows:
    - panes:
        - shell_command:
            # Executes immediately
            - echo "___$((11 + 1))___"
            # Delays before sending 2 seconds
            - cmd: echo "___$((1 + 3))___"
              sleep_before: 2
            # Executes immediately
            - cmd: echo "___$((1 + 3))___"
            # Pauses 2 seconds after
            - cmd: echo "Stuff rendering here!"
              sleep_after: 2
            # Executes after earlier commands (after 2 sec)
            - cmd: echo "2 seconds later"
  ```

- #701: `tmuxp freeze` now accepts `--quiet` and `--yes` along with the
  `--config-format` and filename (`--save-to`). This means you can do it all in
  one command:

  `tmuxp freeze -yqo .tmuxp.yaml`

  Or bind it to `.tmux.conf` itself: `bind -T root C-s run-shell "tmuxp freeze -yqo .tmuxp.yaml"`

  Credit: [@davidatbu](https://github.com/davidatbu)

- #672: Panes now accept `shell` for their initial command.

  Equivalent to `tmux split-windows`'s `[shell-command]`

  ```yaml
  session_name: Pane shell example
  windows:
    - window_name: first
      window_shell: /usr/bin/python2
      layout: even-vertical
      suppress_history: false
      options:
        remain-on-exit: true
      panes:
        - shell: /usr/bin/python3
          shell_command:
            - print('This is python 3')
        - shell: /usr/bin/vim -u none
          shell_command:
            - iAll panes have the `remain-on-exit` setting on.
            - When you exit out of the shell or application, the panes will remain.
            - Use tmux command `:kill-pane` to remove the pane.
            - Use tmux command `:respawn-pane` to restart the shell in the pane.
            - Use <Escape> and then `:q!` to get out of this vim window. :-)
        - shell_command:
            - print('Hello World 2')
        - shell: /usr/bin/top
  ```

### Improvements

- Improve `tmuxp freeze` UX flow, credit @joseph-flinn (#657, in re: #627)
- `tmuxp freeze` will now detect the attached session if no session name
  is specified. Credit: @will-ockmore. (#660)

### Bugs

- Fix loading of `.yml` files with `tmuxp convert`, thank you @kalixi! (#725)

### Internal API

- #752: Command structure (internal API)

  To pave the way for per-command options such as `enter: false` (#53), commands are now a different format:

  Before, [`str`](str):

  ```python
  "echo hello"
  ```

  After, {py:class}`dict`:

  ```python
  {
     "cmd": "echo hello"
  }
  ```

  This is purely internal. Normal usage should be the same since the
  configuration emits the equivalent result.

- #752: Configuration parsing refactorings

### Development

- Run through black + isort with string normalization (#738). This way we can
  use black without any configuration. (One-time, big diff)
- Run codebase through pyupgrade (#745)
- Add `codeql-analysis.yml` to try it out

### Documentation

- Move to `furo` sphinx theme
- Reorganize documentation into sections
- Added examples for `enter: false` and `sleep: [second]`

## tmuxp 1.9.4 (2022-01-10)

### Packaging

- `poetry build` used to package in place of `python setup.py build` (#729)

  Package maintainers: If you run into any issues check in at #625 and file an issue.

  Additionally, `libtmux` has been pinned to a similar release at
  [0.10.3](https://pypi.org/project/libtmux/0.10.3/) which has used the new
  build process.

- `poetry publish` instead of `twine upload dist/*` (#729)

  Similar to the above, reach out to the #625 issue if you bump into problems.

### What's new

- `tmuxp edit` for configuration changes (#707, @GlebPoljakov)

  Inside of configuration directory: `tmuxp edit yourconfig`

  Inside a project: `tmuxp edit .`

### Removed support

- Python 3.6 support has been removed (#726)

### Development

- We are trying `.pre-commit-config.yaml` in pull requests to automate
  black, isort and flake8 for those who forget (#726)
- Poetry update 1.1.7 -> 1.1.12 and use new installer URL (#726)

## tmuxp 1.6.1 (2020-11-07)

- #641 Improvements to `shell`

  Thanks [django-extensions] (licensed MIT) for the shell detection abstraction.

  - Deprecate `shell_plus`
  - `tmuxp shell` now detects the best shell available by default
  - Python 3.7+ with `PYTHONBREAKPOINT` set in env will drop into `pdb` by
    default
  - Drop into `code.interact` by default instead of `pdb` if no third
    party shells found
  - New options, override:

    - `--pdb`: Use plain old `breakpoint()` (python 3.7+) or
      `pdb.set_trace`
    - `--code`: Drop into `code.interact`, accepts `--use-pythonrc`
    - `--bpython`: Drop into [bpython]
    - `--ipython`: Drop into [ipython]
    - `--ptpython`: Drop into [ptpython], accepts `--use-vi-mode`
    - `--ptipython`: Drop into [ipython], accepts
      `--use-vi-mode`

[django-extensions]: https://github.com/django-extensions/django-extensions

## tmuxp 1.6.0 (2020-11-06)

- #636 + #638 New command: `tmuxp shell`

  Automatically preloads session, window, and pane via [libtmux]
  {ref}`API objects <libtmux:api>` and makes them available in a python
  console.

  ```{image} _static/tmuxp-shell.gif
  :width: 100%

  ```

  As of {ref}`1.6.1 (above) <v1-6-1>`, `tmuxp shell` will find the most
  feature-rich shell available. If you have [ipython], or
  [bpython] available, it will be selected automatically. Pass `--pdb`
  to use standard library pdb, or `--code` to use `code.interact`.

  In python 3.7+, supports `PYTHONBREAKPOINT`:

  ```{code-block} sh

  $ pip install --user ipdb
  $ env PYTHONBREAKPOINT=ipdb.set_trace tmuxp shell

  ```

  You can execute python directly via `-c`:

  ```{code-block} sh

  $ tmuxp shell -c 'print(session.name); print(window.name)'
  my_server
  my_window

  $ tmuxp shell my_server -c 'print(session.name); print(window.name)'
  my_server
  my_window

  $ tmuxp shell my_server my_window -c 'print(session.name); print(window.name)'
  my_server
  my_window

  $ tmuxp shell my_server my_window -c 'print(window.name.upper())'
  MY_WINDOW

  ```

  , {class}`Window`, and {class}`Pane` continues.

  - {class}`Server` has @property {meth}`Server.sessions`, which is forward
    to {meth}`Server.list_sessions()` (kept to keep tmux commands in
    serendipty with api), {meth}`Server._list_sessions()` returns dict
    object from {meth}`Server.__list_sessions()` tmux command.
    {meth}`Server.__list_sessions()` exists to keep the command layered so
    it can be tested against in a matrix with travis and compatibility
    methods can be made.
  - {class}`Session` now has @property {meth}`Session.windows` returning a
    list of {class}`Window` objects via {meth}`Session.list_windows()`.
    @property {meth}`Session._windows` to {meth}`Session._list_windows()`
    to return a list of dicts without making objects.
  - {class}`Window` now has @property {meth}`Window.panes` returning a
    list of {class}`Pane` objects via {meth}`Window.list_panes()`.
    @property {meth}`Window._panes` to {meth}`Window._list_panes()`
    to return a list of dicts without making objects.

## tmuxp 0.1-dev (2013-10-18)

- internal overhaul of {class}`Server`, {class}`Session`,
  {class}`Window`, and {class}`Pane`.

  - `Session`, `Window` and `Pane` now refer to a data object
    in {class}`Server` internally and always pull the freshest data.
  - A lot of code and complexity regarding setting new data for objects
    has been reduced since objects use their unique key identifier to
    filter their objects through the windows and panes in `Server`
    object.
  - `Server` object is what does the updating now.

- [project] some research into supporting legacy tmux versions. tmux 1.6
  and 1.7 support seem likely eventually if there is enough demand.
- python 3 support

## tmuxp 0.1-dev (2013-10-17)

- updated README docs with new project details, screenshots
- new example `.tmuxp.yaml` file updated to include

  {class}`Server`, {class}`Session`, {class}`Window`, {class}`Pane` now
  have {meth}`util.TmuxRelationalObject.getById` (similar to [.get()] in
  [backbone.js] collection), {meth}`util.TmuxRelationalObject.where` and
  {meth}`util.TmuxRelationalObject.findWhere` ([.where()] and
  [.findWhere()]), to easily find child objects.
- tmux object mapping has been split into
  {class}`util.TmuxMappingObject`. The mapping and the relational has been
  decoupled to allow {class}`Server` to have children while not being a
  dict-like object.
- {class}`Server`, {class}`Session`, {class}`Window`,
  {class}`Pane` now explicitly mixin subclasses.

## tmuxp 0.1-dev (2013-10-15)
