highlightBothThemes

suspend fun highlightBothThemes(code: String, language: String, lightTheme: HighlightTheme, darkTheme: HighlightTheme): Result<ThemedHighlightResult>

Highlights code once and produces a ThemedHighlightResult with both a light and a dark androidx.compose.ui.text.AnnotatedString.

The JS tokeniser runs once; the two colour maps are applied to the same HTML output, so theme switching after the call returns is instant - no extra WebView round-trip.

// Inside a coroutine (e.g. viewModelScope.launch or LaunchedEffect):
engine.highlightBothThemes(
    code       = sourceCode,
    language   = "typescript",
    lightTheme = HighlightTheme.tomorrow(),
    darkTheme  = HighlightTheme.tomorrowNight(),
).onSuccess { result ->
    val display = if (isDark) result.dark else result.light
}

Return

Result wrapping a ThemedHighlightResult, or Result.failure with a HighlightException on error.

The source code to highlight.

language

Highlight.js language identifier (e.g. "kotlin", "typescript").

lightTheme

Theme applied to produce ThemedHighlightResult.light.
