Types

type ASCIIPuter

type ASCIIPuter struct {
	// contains filtered or unexported fields
}

An ASCIIPuter makes it easy to do ASCII input to and output from a Puter.

func ASCIIfy

func ASCIIfy(p *Puter) *ASCIIPuter

ASCIIfy wraps a Puter in an ASCIIPuter.

func (*ASCIIPuter) Exec

func (a *ASCIIPuter) Exec(input string) string

Exec executes the given command and returns its output.

func (*ASCIIPuter) Input

func (a *ASCIIPuter) Input(in string)

Input feeds some ASCII input to the Puter.

func (*ASCIIPuter) Output

func (a *ASCIIPuter) Output() string

Output returns the current ASCII-interpreted output of the Puter.

func (*ASCIIPuter) Result

func (a *ASCIIPuter) Result() int

Result returns the non-ascii result.

func (*ASCIIPuter) Run

func (a *ASCIIPuter) Run() bool

Run runs the puter until it wants more input.

type Program

type Program []int

A Program written in Intcode.

func LoadProgram

func LoadProgram(filename string) Program

LoadProgram loads an intcode program from a file.

type Puter

type Puter struct {
	// contains filtered or unexported fields
}

A Puter is an intcode computer.

func NewPuter

func NewPuter(prog Program) *Puter

NewPuter creates a new Puter.

func (*Puter) RunNB

func (p *Puter) RunNB() bool

RunNB runs the intcode program until it either quits or needs more input.

func (*Puter) Stdin

func (p *Puter) Stdin(stdin []int)

Stdin sets the computer's input stream.

func (*Puter) StdinCh

func (p *Puter) StdinCh(ch <-chan int)
