# NovaBASICv2

![novabasic](https://github.com/StynVanDeHaterd/NovaBASIC/assets/9077578/80dc5727-aeb1-4a8d-b800-6cc74a2b202f)

Second implementation of my own programming language called NovaBASIC. Made in C# .NET 8, using Blazor as front-end.

## Examples

Standard operations in NovaBASIC:

### Variables

```

LET i = 50

IMMUTABLE j = 100

LET myArray = NEW[10]

```

### Loops

```

FOR LET i = 0 TO 10

    PRINT i

END

FOR LET i = 0 TO 10 STEP 2

    PRINT i

END

LET j = 0

WHILE j < 10

    PRINT j

    j = j + 1

ENDWHILE

LET h = 10

REPEAT

    PRINT h

    h = h + 1

UNTIL h > 20

```

### Functions & References

```

FUNC myFunc(arrRef, index)

    arrRef[index] = 20

ENDFUNC

LET myArray = NEW[5]

myFunc(REF myArray, 4)

```

### If/Else

```

LET i = 6

IF i % 2 == 0 THEN

    PRINT "Value " + i + " is dividable by 2."

ELSEIF i % 3 == 0 THEN

    PRINT "Value " + i + " is dividable by 3."

ENDIF

```

### Switch

```

LET dayOfWeek = "Friday"

SWITCH dayOfWeek

    CASE "Monday":

        PRINT "Start of the workweek"

        BREAK

    CASE "Friday":

        PRINT "End of the workweek"

        BREAK

    DEFAULT:

        PRINT "Middle of the workweek"

        BREAK

ENDSWITCH

```

### Guard

```

FUNC myFunc(param)

    GUARD param < 20 ELSE

        PRINT "Too much!"

        RETURN null

    ENDGUARD

    RETURN param * 50

ENDFUNC

LET i = 10

LET j = 20

myFunc(i)

myFunc(j)

```

### Type Checking

```

STRUCT Person

    Name

ENDSTRUCT

FUNC GetNameLength(p)

    GUARD p IS Person ELSE

        PRINT "Parameter must be a 'Person'!"

        RETURN -1

    ENDGUARD

    RETURN COUNT(p.Name)

ENDFUNC

PRINT GetNameLength(NEW Person("Bob Ross"))

PRINT GetNameLength(25)

```

### Array Slicing

```

LET arr = NEW[10]

LET firstTwo = arr[:3]

LET lastSeven = arr[3:]

LET between = arr[2:5]

LET inTwo = arr[1:10:2]

```

### Import/Export (Desktop Only)

```

//File1.nova

IMMUTABLE myConst = 3.14

STRUCT myStruct

    Val

ENDSTRUCT

EXPORT

    myConst,

    myStruct

ENDEXPORT

//File2.nova

FUNC myFunc(var1)

    PRINT var1

ENDFUNC

EXPORT

    myFunc

ENDEXPORT

//File3.nova

IMPORT FROM "File1"

IMPORT "MyFunc" FROM "File2"

LET i = NEW myStruct(myConst)

myFunc(i)

```
