v0.15.2.0

0.15.2.0 (2025-08-06)

 *  Fix case-insensitivity of class names for `eval` code blocks (#192).
    Class names are case-insensitive (like in HTML), but we were treating them
    as case-sensitive.

 *  Under `theme:`, individual headers can now also be customized (#162).

    The configuration blocks under `headers` accepts a `style` list, a `prefix`
    string and an `underline` string that is repeated match the width of the
    header. `align: center` can be used to horizontally center the header.

    ```yaml
    patat:
      theme:
        headers:
          h3:
            style: [vividRed]
            prefix: '### '
            underline: '-~-~'
            align: center
    ```

v0.15.1.0

0.15.1.0 (2025-04-26)

 *  Add a `syntax` option for `eval` blocks (#187).  This allows you to set
    the syntax highlighting to be used for the _output of the evaluated code_,
    for example:

        ---
        patat:
          eval:
            ruby:
              command: irb --noecho --noverbose
              syntax: json
        ...

        Here is a code block:

        ```ruby
        puts '{"hello": "world"}'
        ```

v0.15.0.0

0.15.0.0 (2025-04-05)

 *  Add [OSC8] support for hyperlinks (#185).  This makes hyperlinks clickable
    in many terminal emulators (see [OSC8 adoption]).

    There is currently no way to detect if a terminal supports this feature,
    so for now this needs to be explicitly turned on in the configuration:

    ```yaml
    patat:
      links:
        osc8: true
    ```

 *  Enable `shortcut_reference_links` by default.  These are reference links
    without the second pair of brackets, e.g.:

    ```markdown
    See [my website].

    [my website]: http://example.com
    ```

 *  Validate settings on slide (#186).

    This validation was present since the introduction of slide settings, but it
    was accidentally removed in v0.14.

 *  Improve reference link rendering.

    This changes the way references are rendered from:

        [example](http://example.com/)
        [example with title](http://example.com/ "title")

    To:

        [example]: http://example.com/
        [example with title]: http://example.com/ title

    This easier to read and more coherent with Pandoc markdown.

v0.14.2.0

0.14.2.0 (2024-03-10)

 *  Fix WezTerm image rendering when using panes (#182).
 *  Bump `ansi-terminal` upper bound to 1.2 and lower bound to 1.1.
    This adds the ability to set colors on underlines.
 *  Bump `pandoc` upper bound to 3.7.
 *  Bump `tasty-quickcheck` upper bound to 0.12.

v0.14.1.0

0.14.1.0 (2024-02-22)

 *  Add image support for WezTerm (#177).
 *  Fix image support in Kitty (#179).
 *  Fix image scroll issue for iTerm2.

v0.14.0.0

0.14.0.0 (2024-02-06)

 *  Align based on final layout for incremental lists and other fragments
    (#174).  This avoids lists "jumping around" as they are revealed when
    using `auto` `margins`.

 *  Rename `fragment` to `reveal` in eval settings.  `fragment` will continue
    to be available for backwards-compatibility.

 *  Use a temporary file to atomically write speaker notes.

    We weren't writing the file all-at-once before, so if you were using a
    simple tool like `tail -F` before, this could cause some speaker notes to
    not be displayed.

 *  Refactor the internal AST to use our own derivation of the Pandoc AST.
    This is a major rework of the internals but should not cause any changes
    visible to the user.

v0.13.0.0

0.13.0.0 (2024-10-30)

 *  Incrementally display output of `eval` commands (#132)

    Rather than waiting for the process to complete and then displaying its
    output, `patat` now fetches the `stdout` and `stderr` as it becomes
    available and refreshes the display.

    This means that by default, **stderr is now displayed as well**.
    To disable displaying `stderr`, you can add `stderr: false` to the eval
    configuration, e.g.:

    ```yaml
    patat:
      eval:
        bash:
          command: bash
          stderr: false
    ```

v0.12.0.1

0.12.0.1 (2024-09-28)

 *  Fix width of code blocks when using wide characters (#171)
 *  Bump `pandoc` upper bound to 3.3.

v0.12.0.0

0.12.0.0 (2024-02-27)

 *  Render tabs in code blocks by expanding them to spaces.  The amount of
    spaces a tab character aligns to is customizable using `tabStop`, e.g.
    `tabStop: 8`.  The default is 4.

 *  Rename eval.wrap to eval.container (#167)

    `wrap` is used at the top-level of settings for wrapping at a certain
    column, and inside `eval` to determine the type in which the result
    is "wrapped". Using the same name for both is confusing, so this adds
    `eval.container` as the new name for `eval.wrap`. `eval.wrap` will continue
    to be supported for the forseeable future, but its use will be discouraged.

    This also changes the values (again keeping the original ones for
    backwards-compat), so the complete changes to a configuration would be:

     -   `wrap: code` becomes `container: code`
     -   `wrap: raw` becomes `container: none`
     -   `wrap: rawInline` becomes `container: inline`

 *  Add a `type: matrix` transition effect, loosely inspired by the 1999 science
    fiction movie.

v0.11.0.0

0.11.0.0 (2024-02-14)

 *  Support wrapping at a specific column (#164)

    Using a specific wrap column, e.g. `wrap: 60`, works well together with
    `auto` margins (see below).

 *  Support centering content with auto margins (#164)

    Configuration is done through the existing `margins` setting.

    To vertically center content, use `top: auto`. To horizontally center
    content, use both `left: auto` and `right: auto`.  For example:

    ```markdown
    ---
    title: Centered presentation
    author: John Doe
    patat:
        margins:
            left: auto
            right: auto
            top: auto
    ...

    Hello world
    ```

    Setting `wrap: true` is recommended when vertically centering content if
    there are any lines that are too wide for the terminal.
