`Dialogue`¶

Multi-speaker transcript with accessible speaker labels and timing metadata.


Import	`from hedron import Dialogue`
Distribution	`hedron`
Backend activity	No
Normal render mode	`RenderMode.FRAGMENT`

Live demo¶

DialogueMulti-speaker transcript with accessible speaker labels and timing metadata.

The preview is a local docs simulation (not a running Hedron server). Interactive demos show a “Simulated HTMX” trace when applicable.

Basic use¶

from hedron import Dialogue
component = Dialogue([{'speaker': 'A', 'text': 'Hello', 'start_ms': 0, 'end_ms': 500}])

Compose under Page for full documents, or return from a fragment route for HTMX swaps.

How it works¶

Phase 0.18 model-demo presentation. Speaker identity must not rely on color alone.

This component's core behavior is server-rendered HTML and does not require a browser runtime. The preview is ordinary semantic HTML, so keyboard, form, link, and disclosure behavior comes from the platform.

Constructor and parameters¶

Dialogue(turns, *, title='Dialogue', class_=None, mark=None)

Parameter	Type	Meaning
`turns`	`Sequence[DialogueTurn \| Mapping]`	Ordered speaker turns with optional timing/tags.
`title`	`str`	Section label.
`mark`	`str \| None`	Optional stable test mark (`data-hedron-mark`).

Composition and backend behavior¶

Keep Dialogue at the smallest semantic boundary. Fragment routes should return only the replaced region and preserve stable target IDs across success, validation, empty, loading, and error responses.

Dialogue is primarily presentational; keep any mutation on an explicit action or component route.

Accessibility¶

Each turn exposes an accessible speaker label; timing/tags are text metadata.

Security¶

Escaping and SafeUrl / TrustedHtml are framework concerns; authorization and data exposure remain application code. Redact secrets before rendering.

Common mistakes¶

Do not use Dialogue as a chat input widget; pair with ChatMessage/ChatInput for interactive chat.
Do not copy docs-preview JavaScript into an application server.

Testing¶

from hedron import RenderMode, render

result = render(component, mode=RenderMode.FRAGMENT)
assert result.html
assert not result.diagnostics
