Brainfuck Task

This is a very small implementation of brainfuck

Implementation Details

I have written this program to only support "+" and "-". And added the functionality to add the operations as required.

How it works

You can run the program by running

go build .
./bf

It will run a terminal waiting for the response

Enter the operator to operate
supported operators: +, -

You can enter the operator in the terminal and will operator based on the provided input

Extendability

You can add custom operations by calling the function The first parameter is the initial value of for the operations to be done

You can add any operation you like, it has to adhere to type Operation

type Operation func(initialValue string) (string, error)

For example if you want to add an operation ^ to sqaure the value, you can just add a operation to map

operations := map[string]Operation{
	"?" : func(initialValue string) (string, error) {
            intVal, err := strconv.ParseInt(value, 10, 32)
            if err != nil {
                return "", err
            }
            intVal *= intVal;
            return fmt.Sprintf("%d", intVal), nil	
    }   
}
NewOperator(initivalValue, operations)

Why not addOperation in Operator

Because I want our Operator to be immutable

How to run tests
