## [0.17.0] - 13/05/2025

Added SVG integration of LiaScript.
LiaScript code can now be embedded into SVG via the `foreignObject` tag, which allows to combine drawings with animations and LiaScript code to make SVG more interactive.

```markdown
<svg width="400" height="250">
<!-- Circle with blue fill and black border -->
<circle cx="100" cy="100" r="80" fill="lightblue" stroke="black" stroke-width="2" />

<!-- Foreign object with LiaScript formula and animation -->
<foreignObject x="10" y="60" width="180" height="40">

           {{1}}
$$
   \sum_{i=1}^\infty\frac{1}{n^2}
      =\frac{\pi^2}{6}
$$

</foreignObject>
</svg>
```

## [0.16.15] - 08/05/2025

- feat: Add `edit` macro that allows to share a link to the course resource for editing.

  ```markdown
  <!--
  edit: true
  -->

  # Open automatically provide a link to the LiveEditor

  https://LiaScript.github.io/LiveEditor/
  ```

  ---

  ... or provide a link to a custom editor


  ```markdown
  <!--
  edit: https://github.dev/username/repo/...
  -->

  # Provide a link to a custom editor
  ```

- feat: [Nostr](https://nostr.com) as data source is now, which means you can host course content on a decentralized storage. A Nostr-URI typically starts with `npub` or `nsec` and is followed by a base64 encoded string. The Nostr-URI can be used in the same way as a normal URL, but it will be resolved via the Nostr protocol.

  > The LiveEditor provides an export to Nostr.

- feat: Chats in classroom mode now can also execute scripts, but the user has to
  explicitly allow this.

- chors: Upgrade npm packages and trystero

  # Classroom

  This will allow to execute scripts in the classroom mode.
  ```

## [0.16.14] - 14/04/2025

- fix(Formulas): Translating the content with Google-Translate does now not affect formulas anymore.
- chors: Npm update of katex, ace, caniuse, etc
- feat: Special ignore comments added `<!---.*--->`

  Since separating HTML-comments with HTML-parameters is difficult,
  compared to only comments. This new parser introduces a comment with at
  least three dashes, which means that the content will be totally ignored.

  `<!--- Everything style="here" will be ignored --->`

  `<!-- everything style="width: 100" data-will be-kept -->`

## [0.16.12] - 04/04/2025

  - header levels defined by number of `#`
  - remove alt from logo
  - multiple aria-polite and aria-live optimizations for quizzes, tables and formulas, and the terminal output

- feat: in script for the modify parameter it is now possible true or false the modification but also to add a string that is used as a code separator to allow modifications only for a certain part

## [0.16.8] - 06/01/2025

- chore: npm update ace, katex, caniuse-lite
- localization: Updated italian translation
- fix(Link): alt unfinished quotations

  Previously not closing quotations where chomped away when a title link
  was defined:

  ```markdown
  [... "closing" ... "open](#link "title")
  ```
- improve(Links): Title with single quotes

  Now it is possible to add title within single quotes to links as well:

  ```markdown
  - [alt](ref 'title')
  - [alt](ref "title")
  ```

- feat(Table): add data-orientation setting

  using the following

  `<!-- data-orientation="vertical|horizontal" -->`

  above a table allows to change the orientation of the generated diagram...

- improve(Platform support): Courses can now also be loaded directly from the following platform, without requiring a proxy, and thus will not cause any CORS issues:

  - [GitLab](https://gitlab.com)
  - [Codeberg](https://codeberg.org)
  

## [0.16.7] - 14/11/2025

- upgrade: ASCII-Art now a bit faster
- improve(Translations): Add lang without translations

  Previously TTS could only be used if it is supported by responsive
  voice. But since LiaScript now allows to use browser supported TTS with
  locally installed languages, this check has become obsolete. TTS is now
  enabled for all comments, even for languages such as Georgian.

## [0.16.6] - 08/11/2024

- improve: LiaScript preview cards with new design
- fix: HTML parser with combined macros

## [0.16.5] - 07/11/2024

- fix: Add escape `\@` for macros, this will allow to pass escaped parameters to macros, which will not be evaluated by the parser.


## [0.16.4] - 29/10/2024

- improve(Index): The course overview now has a masonry organization of courses with different size for cards. This will allow for a better overview of the courses and a more dynamic layout.
- improve(Cards): Better Design with more options
- improve(Google-Translation): Annoying pop-ups and hover effects are now suppressed.
- Upgrade:
  
  - [x] npm Dexie 4.0.9
  - [x] elm andre-dietrich/parser-combinators
  - [x] elm f0i/statistics
  - [x] elm tesk9/accessible-html

- feat: add . to \\. escape characters

  ``` markdown
  Next to escaping ellipsis, \.\.\. this will now allow to add numbers to lists:

  * 5\.1 ....
  * 5\.2 ....
  ```

- fix(Parser): Arrows have been overwritten by typography

  Rules for typographical dashes kicked in before the arrows, which blocked
  left to right arrows to don't be detected correctly.

  `-->  ->`

## [0.16.3] - 21/10/2024

- feat(Typography): It is now possible within a LiaScript Markdown to apply the following typographical elements:

  - A sequence of dashes is now translated into:

    1. - (single dash): Hyphen or minus sign
    2. -- (double dash): En dash
    3. --- (triple dash): Em dash

  - Translate ... to unicode ellipsis

  - Language base quotes single and double are translated into their typographical counterparts, based on the language of the course. Additionally these two types have been added to the escaped elements `\"` and `\'`.

- improve(HTML-Parser): The parsing speed for HTML has been increased, due to a new abort mechanism, which will stop the parsing of a HTML end-tag has been detected. This will prevent the parser from running into an long loop.

- improve(Parser): Some minor improvements for regular expressions have been applied after benchmarking the parser.

## [0.16.2] - 04/10/2024

- feat(Zip): Courses can now be uploaded as ZIP files, which will be automatically extracted and loaded. Also courses can be hosted as Zip-files, which will be extracted on the fly.

  Additionally, a URL translation for download links for Zip-files stored on the following services is now supported:

  - [GitHub](https://github.com)
  - [OneDrive](https://onedrive.live.com)
  - [Dropbox](https://www.dropbox.com)

- feat(Table): Add `data-sortable` to tables, which can be set to `true` or `false` to enable or disable sorting for a column.
  By default every column is sortable, but this changed globally or on a per column basis. The defintion in the column header will overwrite the global setting.

  ```markdown
  <!-- data-sortable="false" -->
  | Header 1 | <!-- data-sortable="true" --> Header 2 |
  | :------- | :------------------------------------- |
  | Item 1   | Item 2                                 |
  | Item 5   | Item 6                                 |
  | Item 9   | Item 10                                |
  | Item 13  | Item 14                                |
  ```

- feat(Table): Tables of type `none` which are not displayed as an visualization have now a non sticky first column. Previously the first column was sticky, while the others could be moved.

- improve(Quiz): Quiz definitions now allow for escaped strings, such that a text-inputs

  `[[a\|b]]`

  or selections allow

  `[[\(a\) | (b) | \[c\]]]`

- feat(Formula): Pass global `.katex` CSS to webcomponent

  Somehow the global styles were not passed to the webcomponent, although
  the shadow-DOM was open. This is now done explizitly by querying all
  definitions for .katex and injecting them into the webcomponent.

## [0.16.1] - 27/09/2024

- feat: Allow to upload LiaScript courses at the Index-page directly from the device as single files or as ZIP archives

- improve(Macro): Escaping of `${` as `\${`

## [0.15.12] - 28/08/2024

- chore: Update npm packages
- improve(Macro): Parameter with more than 3 backticks

  The macro parameters formats had the following format

  - `single,line,parameter,with,commas`
  - ``` multiline `parameters` ```

  The 3 backticks were hard-coded, hence it was not possible to pass markdown-blocks with code-blocks. Now it is possible to define multiline parameters with more than 3 backticks, allowing for more complex parameters. Basically it works like an ordinary code-block now, which can contain other code-blocks with less backticks.

## [0.15.11] - 22/08/2024

- improve: Code-Terminal, which scrolls to the bottom on every new output
- feat: Add backslash followed by a newline in a paragraph, will result in a line-break

- improve: Translations for code, now also translations for code copy-buttons
- improve: onload will block the execution of other scripts until it is finished

## [0.15.9] - 12/08/2024

- feat: Add pitch and rate settings to TTS comments.
  
  - The pitch can be set between 0 and 2, the rate between 0.1 and 5.

  - Rate is also added to video and audio comments, while keeping the pitch constant.

  - Additionally, the pitch and rate can be modified within the script for the current comment or replayed element as well

    ```markdown
    <!-- data-rate="2.0" data-pitch="1.2" -->
        --{{0}}--
    This element will be read with a higher pitch and rate.

    <!-- data-rate="1.3" -->
        --{{0}}--
    !?[video](/path/to/video.mp4)
    This video will be played with a higher rate, but the pitch will stay the same.

    <!-- data-rate="2.0" data-pitch="1.2" -->
        {{|>}}
    Also for this local playback, the custom data rate and pitch will be used to overwrite the default settings 
    ```

    Currently a room-name and a course-URL are used to generate a unique ID
    for a room. However, the user has now also the possibility to define a

    ID.

## [0.10.12] - 02/06/2022

- fix: Bug in heatmap-representation of tables ...

## [0.10.11] - 30/05/2022

- improve: DOM - handling

  DOM can now be set to `persistent: on` within the main-header-comment. This way
  no DOM-elements of other slides will be deleted anymore, they will only set to
  `hidden`. This way other systems, that need to manipulate the DOM, can now safely
  interact with LiaScript.

  But, when dealing with a lot of iframes, movies, simulations, etc. It is still
  wise to use the `persistent: off` mode. This way, videos and sound are closed,
  when switching the slide, otherwise they will still remain active, but hidden.

  However, by default the persistency of slides is disabled, it has to be enabled
  globally, but is can also be redefined per slide:

  ```markdown
  <!--
  persistent: on
  -->

  # Title

  ...

  ## Sub-Section

  <!--
  persistent: off
  -->

  ## Sub-Section 2

  <!--
  persistent: true
  -->

  Switching on is not required, if it is globally activated.
  ```

- Add Classroom functionality within the share section, currently supported are

  - [BeakerBrowser](https://beakerbrowser.com)
  - [PubNub](https://www.pubnub.com)
  - [GunDB](https://gun.eco)

  This will at the moment synchronize quizzes and survey, and provide an overview
  on the results/inputs to all connected users. All data is only stored/synchronized
  between the users not at the backend. And when a user leaves the room, her or she
  takes the data with them, which will result in an update overview.

- Complete rebuild of the internal messaging pipeline to a service architecture.
- Better API, all functionality is now accessible from within a global `window.LIA`
  object.
- A set of new macros, which can be used to disable setting components:

  - `@classroom: disable`
  - `@sharing: false`
  - `@translateWithGoogle: off`

  You can use words like `false`, `disabled`, `0`, `OFF` ... LiaScript will recognize
  them as negative. All other words like `wouldLoveToSeeThisFeature` are treated
  as positive. **But better stick with `false/true`, `on/of`, `disable/enable`**

- Improved CSS for printing. This allows to generate beautiful content of a slide,
  with preserved links, if media or iframes are added.

  since it creates additional http traffic. Currently supported types of
  links:

  - Links to LiaScript courses, which have to contain the URL of the
    Markdown file
  - Links to services that support oEmbend
  - Other sites with meta information as OpenGraph, TwitterCards, otherwise
    the first image, header, and paragraphs are grabbed to create the tooltip

## [0.9.47] - 14/01/2022

- improve: Video resources via Multimedia links

  - Add support for the TU Bergakademie Freiberg video platform

    from above and is also visible for exports

## [0.9.45] - 06/01/2022
