Across the webR-Verse to v0.2.0

Feature

• Implements changes required to run webR v0.2.0

Demo, Demo, Demo!

Bug fix

• Attempted to resolve missing service workers for published Quarto webR enabled documents on https://quarto.pub

Deployment

• Added a GitHub actions website deployment workflow to generate sample pages.
• Added a devcontainer.json for development on GitHub
• Added a script to update the version of Quarto used inside of the devcontainer.json.

Accessibility with the Monaco Editor

Breaking Changes

• We've transitioned the code editor used in the quarto-webr extension to Monaco Editor from CodeMirror for improved accessibility.
  • Special thanks go out to JooYoung Seo (Website) for identifying the accessibility issue and submitting a pull request to incorporate the editor.

Features

• Code editing areas on the Quarto document now use the Monaco Editor for improved accessibility.
• Execute code using keyboard shortcuts:
  • Run selected code using: [Cmd + Enter] on macOS or [Ctrl+Enter] on Windows
  • Run the entire code area using: [Shift+Enter]
• Dynamically growing code editor as new lines are added.
• Announcing the status changes of webR initialization states through arias.

Setting Options in Document YAML

Features

• Upgraded the version of webR to use v0.1.1.
• Set options directly inside the document's YAML header to control webR:
  • Support is available for setting the following WebR.WebROptions options:
    • home-dir: The WebAssembly user’s home directory and initial working directory (Documentation). Default: '/home/web_user'.
    • base-url: The base URL used for downloading R WebAssembly binaries. (Documentation). Default: 'https://webr.r-wasm.org/[version]/'.
    • service-worker-url: The base URL from where to load JavaScript worker scripts when loading webR with the ServiceWorker communication channel mode (Documentation). Default: ''.
• webR initialization status stages are now described and shown as stoplights (inspired by Bob Rudis)
  • show-startup-message: Display in the document header the state of WebR initialization. Default: true
  • show-header-message: Display in the document header whether COOP and COEP headers are in use for faster page loads. Default: false

Execute webr cells when developing in VS Code or RStudio

Breaking Changes

• We've transitioned to using the {webr-r} code cell designation from our original {webr} designation.
  • The {webr-r} tag allows for code cell evaluation prior to rendering the document
  • Moreover, the {webr-r} component does not need to be registered under the knitr compute engine.

Please update code cells from:

```{webr}

```

To:

```{webr-r}

```

Escape Escape!

Bugfix

• Escape characters \ are further escaped.

```{webr}
add_one <- \(x) x + 1
add_one(2)
```

Should now appear in a webR code cell as:

add_one <- \(x) x + 1
add_one(2)

Documentation

• Added details on how to host webR content
• Added additional examples and details in the webr-demo.qmd file.

All about that margin

Bug Fixes

• Fixed the error of figure margins too large due to canvas sizing issues.
• Removed the attempt to switch between / and '' if COOP and COEP are not present. Defaults to relative directory.

Initial Release: Democratizing Data Science

Features

• Enable webR code cells inside of a Quarto document.
