# Simple BASIC language implementation

The goal of this project is to create a simple implementation of a BASIC-like language.
No need to do complex thing, just to create a simple interpreted language that can be used to do some arithmetics
and create for ex a number guessing game.

## Technology

We will create our own regex engine

## Syntax

One instruction set per line

Instruction sets avalaibles:

### Commentary

can only use single line comments with `#`

```
# this is a comment
```

### Expression evaluation

can only operate on integer

function calls: func(arg_a, arg_b)
operators: +, *, /
booleans operators: not, and, or,

### function definition

```
function {NAME}
begin
...
end
```

### Set a variable

```
set {VARNAME} to {EXPRESSION}
```

### Conditional structure

```
if {EXPRESSION} then
begin
    ...
end
```

### Conditional loop

```
while {EXPRESSION} do
begin
    ...
end
```

### Unconditional loop

```
repeat {EXPRESSION THAT EVALUATE TO INT}
begin

end
```

### std functions

```
put_stdout()
take_stdin()
int_of_string()
random_int(min, max)
```
