Members

Functions

addBookmark integer addBookmark(): adds a "bookmark" to the last element on stack, so later on, relative to current peek index, bookmark index can be read.
addInstruction bool addInstruction(string instName, string argument, string error)
bool addInstruction(string instName, string argument): appends an instruction
addInstructionToTable bool addInstructionToTable(NaInstruction instruction): adds an instruction to the instruction table
addJumpPos void addJumpPos(string name): adds a jump position
bookmarkRelIndex integer bookmarkRelIndex(uinteger id): gets relative index from current stack index to a bookmark
getArgumentsNaData NaData[] getArgumentsNaData(): Call resolve before this.
getBytecodeCodes ushort[] getBytecodeCodes(): Call resolve before this or prepare for crashes
getBytecodePointers void delegate()[] getBytecodePointers(): Call resolve before this or prepare for crashes
getBytecodePretty string[] getBytecodePretty()
hasInstruction bool hasInstruction(string name, NaInstruction instruction)
bool hasInstruction(string name)
readByteCode string[] readByteCode(string[] input): Reads from a string[] (follows spec/syntax.md)
removeBookmark bool removeBookmark(uinteger id): removes a bookmark
resolve string[] resolve(): goes over bytecode, checks if there are any errors, and converts jump positions to indexes i.e: makes the byte code a bit more ready for execution
