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.:

  patat:
    eval:
      bash:
        command: bash
        stderr: false
  

0.12.0.1 (2024-09-28)

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

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.

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:

  ---
  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.

0.10.2.0 (2023-11-25)

• Add eval.wrap option

  This adds a new wrap section to the eval configuration.

  By default, the output is wrapped in a code block again with the original syntax highlighting. You can customize this behaviour by setting wrap to:

  • code: the default setting.
  • raw: no formatting applied.
  • rawInline: no formatting applied and no trailing newline.

  You can use rawInline to draw graphics. In order to do that, for example, we could configure kitten code snippets to evaluate using Kitty's command icat. This uses the rawInline code setting to ensure that the resulting output is not wrapped in a code block, and the fragment and replace settings immediately replace the snippet:

  ---
  patat:
    eval:
      kitten:
        command: sed 's/^/kitten /' | bash
        replace: true
        fragment: false
        wrap: rawInline
  ...
  
  See, for example:
  
  ```kitten
  icat --align left dank-meme.jpg
  ```
  

0.10.1.1 (2023-10-18)

• Fix issues in text wrapping when starting a transition

  This could show transitions using different wrapping or dropped characters when a line extends past the terminal width.

0.10.1.0 (2023-10-15)

• Add dissolve transition effect (#150)

• Add random transitions (#151)

  Set transition type to random to randomly sample transition effects

0.10.0.0 (2023-10-12)

• Add transition effects (#149)

  This adds a framework for setting transition effects in between slides. Only a single transition type is implemented at this point, slideLeft.

  Example configuration:

  patat:
    transition:
      type: slideLeft
      frames: 24  # Optional
      duration: 1  # Seconds, optional
  

• Allow overriding certain settings in slides (#148)

  Configuration was typically done in the metadata block of the input file, or in a per-user configuration. These settings are applied to the entire presentation.

  We now allow selectively overriding these settings on a per-slide basis, by adding one or more config blocks to those slides. Config blocks are comments that start with config:. They can be placed anywhere in the slide.

  # This is a normal slide
  
  Normal slide content
  
  # This slide has a different colour header
  
  <!--config:
  theme:
    header: [vividYellow]
  -->
  
  Wow, how did that happen?
  

• Allow configuring top margin (#147)

0.9.2.0 (2023-09-26)

• Read configuration from XDG standard directory (#146)

  The per-user patat configuration file was $HOME/.patat.yaml, which does not follow the XDG standard. We now support $XDG_CONFIG_DIRECTORY/patat/config.yaml (typically $XDG_CONFIG_DIRECTORY is set to $HOME/.config) which is compliant with the standard.

  Note that $HOME/.patat.yaml is still supported for backward-compatibility, but anything in $XDG_CONFIG_DIRECTORY takes precedence.

• Support filenames in bash completion (#145) (#126)

0.9.1.0 (2023-09-25)

• Fall back to forcing UTF-8 if decoding fails (#144) (#127)

  When we try to read a file that is encoded in UTF-8, and the system locale is not set to UTF-8, the GHC runtime system will throw an error.

  While this typically indicates that the user should update their system locale using e.g. the LANG environment variable, we want to provide a good initial experience for people unfamiliar with this, and in 2023 it's reasonable to assume files may be encoded in UTF-8.

• Dependency updates:

  • Bump skylighting upper bound to 0.15 (#143)

0.9.0.0 (2023-09-13)

• Add proper support for speaker notes (#142)

  You can configure patat to write the speaker notes for the current slide to a file whenever the slide changes:

  patat:
    speakerNotes:
      file: /tmp/notes.txt
  

  Then, you can display these in a second terminal (presumably on a second monitor) by just displaying this file whenever it changes. entr is one way to do that:

  echo /tmp/notes.txt | entr -s 'clear; cat /tmp/notes.txt'
  

  Alternatively, just use a second patat instance with --watch enabled:

  patat -w /tmp/notes.txt
  

• Add support for showing plain text files (#141)

  This isn't super useful on its own, it's meant to support speaker notes.

• Add syntaxDefinitions to settings (#140)

  This allows users to add custom kate highlighting XML files in the settings:

  ---
  patat:
    syntaxDefinitions:
    - 'impurescript.xml'
  ...
  
  Here is some *im*purescript:
  
  ```impurescript
  ...
  ```
