Markdown

Markdown highlighting, covering both block structure (headings, list markers, fenced code blocks, link destinations) and paragraph-body inline constructs (emphasis, strong, link text, code spans, image components, hard line breaks, backslash escapes).

Backed by the split block + inline grammars from tree-sitter-grammars/tree-sitter-markdown. Uses the core sub-tree injection mechanism: block parse runs on the whole document, inline highlights re-apply to each (inline) byte range.

Capture names emitted by the upstream queries (text.title, text.literal, text.uri, text.reference, text.emphasis, text.strong) have no typed field on SyntaxTheme; style them via extras:

theme.copy(
  extras = mapOf(
    "text.title"     to SpanStyle(fontWeight = FontWeight.Bold),
    "text.emphasis"  to SpanStyle(fontStyle = FontStyle.Italic),
    "text.strong"    to SpanStyle(fontWeight = FontWeight.Bold),
    "text.literal"   to SpanStyle(fontFamily = FontFamily.Monospace),
    "text.uri"       to SpanStyle(color = Color.Blue, textDecoration = TextDecoration.Underline),
    "text.reference" to SpanStyle(color = Color.Cyan),
  ),
)

punctuation.special / punctuation.delimiter fall back to the typed punctuation field via SyntaxTheme.resolve's dotted-prefix lookup; string.escape falls back to the typed stringEscape field.

Fenced-code-block multi-language injection (highlighting Kotlin / Python / etc. inside fenced code) is not supported — fenced bodies render under the base style. Future work may add this via the same injection mechanism.
