Features

These features are illustrated in our Demo.

@prosemark/core

Section titled “@prosemark/core”

  • Inline styles including italics, bold text, code spans, and strike-throughs. Highlights using the ==highlight== syntax are planned.

  • Both ATX Headings (# My Heading) and Setext Headings (headings over a line with ===== or -----) are supported.

  • Unordered lists using - and ordered lists using 1. are supported. Ordered lists using + are not yet supported.

  • Task lists following the - [ ] My Task syntax are supported.

  • Images using the ![](https://image-url...) syntax are supported. Setting the image width via GitHub like syntax is planned.

  • Block quotes (including nested block quotes) are supported.

  • Horizontal rules using the --- syntax are supported.

  • YAML frontmatter blocks at the top of a document (--- … ---) are supported and parsed as YAML.

@prosemark/render-html

Section titled “@prosemark/render-html”

  • HTML Blocks inside markdown can be rendered. HTML content is sanitized using DOMPurify.

  • Folded HTML blocks use block replace widgets: an outer shell avoids vertical margins (padding only), and an inner flow-root wrapper contains margins from rendered elements (for example headings) so CodeMirror’s line layout stays accurate. requestMeasure runs after updates and when the widget resizes (ResizeObserver where available).

  • Inline HTML is not supported yet.

@prosemark/paste-rich-text

Section titled “@prosemark/paste-rich-text”

  • Makes it possible to paste rich text as fully-formatted markdown.

  • Provides the Ctrl/Cmd+Shift+V command for pasting without formatting.

@prosemark/spellcheck-frontend

Section titled “@prosemark/spellcheck-frontend”

  • Does not include a dictionary or spelling engine; you compute SpellcheckIssue ranges (for example with nspell or a remote API) and expose them through the spellcheckIssues facet.

  • Renders wavy underlines for misspelled ranges and keeps decorations mapped across document edits so ranges stay valid.

  • Shows a tooltip on interaction (including keyboard shortcuts from spellcheckKeymap): suggestions from the issue and/or from an async suggestionFetcher facet, plus custom actions via spellcheckActions (for example “add to word list”).
