Literal byte value (prefixed with #)

LiteralShort(u16)

Literal short value (prefixed with #)

Instruction(Instruction)

Instruction with mode flags

LabelDef(Rune, String)

Label definition

LabelRef

Label reference

Fields

label: String

rune: Rune

token: TokenWithPos

SublabelDef(TokenWithPos)

Sublabel definition

SublabelRef(TokenWithPos)

Sublabel reference

RelativeRef(TokenWithPos)

MacroDef(String, Vec<AstNode>)

Macro definition

MacroCall(String, usize, usize)

Macro call (name, line, position)

RawString(Vec<u8>)

Raw string data

Include(TokenWithPos)

Include directive

DotRef(TokenWithPos)

Dot reference - generates LIT + 8-bit address (like uxnasm’s ‘.’ rune)

SemicolonRef(TokenWithPos)

Semicolon reference - generates LIT2 + 16-bit address (like uxnasm’s ‘;’ rune)

EqualsRef(TokenWithPos)

Equals reference - generates 16-bit address directly (like uxnasm’s ‘=’ rune)

CommaRef(TokenWithPos)

Comma reference - generates LIT + relative 8-bit address (like uxnasm’s ‘,’ rune)

UnderscoreRef(TokenWithPos)

Underscore reference - generates relative 8-bit address (like uxnasm’s ‘_’ rune)

QuestionRef(TokenWithPos)

Question reference - generates conditional jump (like uxnasm’s ‘?’ rune)

ExclamationRef(TokenWithPos)

Exclamation reference - generates JSR call (like uxnasm’s ‘!’ rune)

ConditionalBlockStart(TokenWithPos)

Conditional block start (e.g., ?{) - lambda id for auto label

ConditionalBlockEnd(TokenWithPos)

Conditional block end (e.g., }) - lambda id for auto label

LambdaStart(TokenWithPos)

Lambda block start ‘{’ (standalone, not ‘?{’)

LambdaEnd(TokenWithPos)

Lambda block end ‘}’ corresponding to LambdaStart
