Top-level pretty-code configuration. Stored on CompileConfig as Option<PrettyCodeOptions>; None means “use built-in defaults”.

Every field below has a sensible default; callers only set the knobs they care about. Field names match the TS-side PrettyCodeOptions shape exported from @gentleduck/md.

Fields

theme: PrettyCodeTheme

Theme spec. String for single-theme, object for multi-mode.

default_mode: Option<String>

Mode key whose colors fill the unprefixed color / background-color attrs. Only meaningful for PrettyCodeTheme::Multi. When unset, resolves to "dark" if present, else the first key.

multi_theme_strategy: Option<MultiThemeStrategy>

Multi-theme DOM strategy. Default CssVars (single tree, faster). Set to Split for one <pre data-theme="..."> subtree per theme (velite parity, ~2x the AST nodes). Single-theme mode ignores this

• there’s only one tree either way.

keep_raw_string: Option<bool>

Keep the __dmcRaw__ attribute on each <pre> so consumer <PreBlock> can offer a Copy button without re-parsing the tree. Default true.

fragment_wrapper: Option<bool>

Wrap the per-theme <pre> blocks in a <div data-dmc-fragment=""> envelope. Default true. Set false to emit just the <pre> siblings (compatible with consumers that wrap themselves).

line_class: Option<String>

Class on each line <span>. Default "line".

highlighted_line_attr: Option<String>

Attribute name set on highlighted lines (from {1,3-5} meta). Default "data-dmc-line-highlighted".

default_language: Option<String>

Language used when a fence has no lang and for unknown langs when Self::fallback_to_plaintext is on. Default "plaintext".

fallback_to_plaintext: Option<bool>

When true (default), unknown fence languages render as plain text. When false, the code block is left as a CodeBlock node for downstream tooling.

render_title: Option<bool>

Render a <figcaption data-dmc-title> from the fence’s title="..." meta. Default true.

include_data_language: Option<bool>

Include data-language on every emitted <pre> and <code>. Default true.

include_pre_background: Option<bool>

Emit a solid background-color on <pre> from the primary theme. Default true. Set to false to skip the inline bg so the outer [data-dmc-fragment] wrapper (or consumer chrome) owns the surface color. Per-mode --dmc-{mode}-bg custom properties are always emitted regardless of this flag, so consumer CSS can still opt back in via var(--dmc-{mode}-bg) if it wants.

skip_languages: Vec<String>

Languages to skip - these blocks are passed through unchanged. mermaid is always skipped (owned by the mermaid transformer); add other langs to keep them as raw CodeBlock nodes.

tab_size: Option<u32>

Expand tab characters to N spaces before highlighting. None preserves original tabs.
