Lucky Lang

This interpreter is VERY-VERY poorly written AND it even gets detected as a virus by windows, so the quality is self evident...
If you, for some reason still want to give it a try, heres the spec:

LuckyLang is Case - Sensitive and New-Line - Sensitive, in fact it relies on new lines to mark the end of a statement

A statement begins with a:

"def" -> DEFINE; "syscall" -> Internal call (println); "call" -> function call; "do" -> While Loop

and ends with a:

"New-Line" -> call, syscall and def statements; "end [expr]" -> just "end" when def function or "end [expression] when do"

Variables are valid for their current scope:

GLOBAL (outside of functions) -> func1 -> func2 (can use all vars from global and func1)

weird, I know, but it gets even better:

Types (which don't really exist in this language) are not defined by name, but by symbol:

"*" -> Number; "$" -> String; "&" -> Boolean; "#" -> Function

This means to declare a boolean variable with the name MyVar I would do the following:

def &MyVar false

When declaring a while-loop the exit-condition is written after the end-statement

When declating a function-block the interpreter expects an end-statement at the end of it, so be sure to put one there

Now, that you effectively know everything this language can do, you can build your own (probably non-functional) programm with it

To do, that, first define the Main-Entry point, by defining a function with the Name "Main" and a singuolar parameter "args" of type String (note: there are technically parameters for functions, but I don't remember if the interpreter actually supports them in call statements)

A Hello World script would look like this:

def $helloWorld "Hello World"
 
def #Main $args
  syscall println helloWorld
end

At least it would look like that, if the interpreter did its job... The current version seems to have some problems regarding the syscall println statement, so yeah...
