#Syntax Support

This page lists what the default pipeline does with common constructs. Render means structured DOM output; placeholder means the position is kept but nothing is evaluated; degrade means a source card plus a diagnostic; block means dangerous content is dropped with a readable hint; ignore means it never reaches the body.

With /expand, resolvers, handlers, or component overrides, output changes. Refer to the dedicated pages for details.

#Combined example

The source below configures no resolvers and covers text, lists, a table, a reference, and the default placeholders:

import { Wikitext } from "react-wikitext";
import "react-wikitext/styles.css";

const source = `== Text and lists ==
'''Bold''', ''italic'', and an [[internal link|internal link]] keep their structure.

* First item
* Second item

== Table and reference ==
{| class="wikitable"
|-
! Column A !! Column B
|-
| Cell || Content<ref>Example reference</ref>
|}

{{Infobox|title=Template placeholder}}
[[File:Example.png|thumb|File placeholder]]`;

export default function Demo() {
  return <Wikitext source={source} lang="en" />;
}

Use the tables to look up a construct; use the example to check the overall output.

#Text and blocks

#Lists and tables

#Links and media

#Templates and functions

Magic words inside templates, functions, and arguments do not affect TOC or category detection.

#HTML and extension tags

#Page-level structure

#Verifying behavior

1. Inspect document.diagnostics for stage and code.
2. Use flattenNodes from /ast to inspect the semantic tree and compare it with the prepared HAST.
3. Use labels to distinguish "not evaluated", "blocked", and "unknown structure".
4. Treat src/ and tests/ as the source of truth; this page follows default behavior.

See Rendering behavior for details and rationale, and Security model for blocking rules.
