Plushie.Widget.RichText (Plushie v0.7.0)

Copy Markdown View Source

Rich text display with individually styled spans.

Spans are typed via Plushie.Widget.RichText.Span. Construct them with span/1 plus chained setters or pass a plain map for ad-hoc cases. Typed spans are encoded automatically; plain maps fall through unchanged.

alias Plushie.Widget.RichText.Span

rich_text "status",
  spans: [
    Span.new("Build ") |> Span.color("#000000"),
    Span.new("ok") |> Span.color("#22aa22") |> Span.underline(true)
  ]

Accessibility

Screen readers see individual spans but cannot infer the overall meaning of the composed text. Set a11y: %{label: "..."} with a plain-text summary so assistive technology can announce the full content in one pass:

rich_text "status", spans: spans,
  a11y: %{label: "Build succeeded in 3.2 seconds"}

For content that updates dynamically, combine label with a live region annotation so changes are announced automatically:

rich_text "output", spans: spans,
  a11y: %{label: summary_text, live: :polite}
