Thistle

Kotlin multiplatform String markup library, inspired by SRML. Thistle is a common parser which produces an AST that can be rendered to a variety of platform-specific UIs.

// Android
val thistle = ThistleParser(AndroidDefaults(context))
binding.textView.applyStyledText(
    thistle,
    "Text with {{b}}bold{{/b}} or {{foreground color=#ff0000}}red{{/foreground}} styles"
)


// Compose (both Android and Desktop)
MaterialTheme {
    ProvideThistle {
        StyledText("Text with {{b}}bold{{/b}} or {{foreground color=#ff0000}}red{{/foreground}} styles")
    }
}


// Console (ANSI codes)
val thistle = ThistleParser(ConsoleDefaults())
printlnStyledText(
    thistle,
    "Text with {{b}}bold{{/b}} or {{red}}red{{/red}} styles"
)
