## Hollow

A simple programming language written in Golang

Stack based with simple instructions, result will always be on top of stack you can use dump(`.`) command to display the result to stdout

```

100 => pushes the given int to stack 

+ => add given number to whatever is at top of stack and push result to stack e.g 100 + 50 pushes 150 to stack(orignal 100 will be replaced)

- => sub two numbers and push result to stack e.g 100 - 50 pushes result to stack

. => prints the current top of stack to stdout

== => compares a number with top of stack e.g  == 100 will return 0 if current number      is not equal to top of stack 1 otherwise

Please  note for all +, == , - operations only one operand is required i.e the right hand side of the operator but there should be a valid value on stack for this

15

+ 10 .

will result in 15 , however

+ 10 . will result in undefined behaviour

```

For an input file:

```

64 + 56 . 

65 + 100 .

200 - 100 .

65 == 100 .

100 - 200 .

100 - 200 == -100 .

```

Output will be:

```

120

165

100

0

-100

1

```

## Compiling and running

There is a sample `example/program.hollow` to check otherwise you can use ur own file with any name with syntax as shown in the file or above examples:

```

go run main.go -o myprogram example/program.hollow

./myprogram

```

For help

```

go run main.go -h

```
