mlan

MLAN (Micro LANguage) is a scripting language (interpreter based) for embedding in Golang applications based on ANTLR4 grammar.

Why yet another scripting language?

Development of language was part of creation C2 framework - c2m, which we position as interface between operator and beacon. MLAN runtime used in operator's CLI to give possibility of extending stocked functionality of interaction with server and beacons, which we provided.

Speed was not a goal of this language, but it can be easily reached by mapping functions written on native Golang.

What about syntax?

We can charactarized MLAN as follows: syntax more like C way, typification and logic of processing like Python way.

This example is C like (a lot of brakets and semicolons):

fn fib(n) {
  if n < 2 {
    return n;
  } else {
    return fib(n-2) + fib(n-1);
  }
}

println(fib(35));

This example is Python like (dynimac typification of variable a):

a = 1;
a = [a, 2, 3, 4];
a = {"kek": a};
a = "hello";
a = a + " world";
println(a);

More info about syntax with examples.

What about data types?

All data types sit on top of abstration as object.

MLAN offered with next data types, which implements object's interface:

• bool (bool in Golang)
• dict (map in Golang, where key is string)
• float (float64 in Golang)
• int (int64 in Golang)
• list (list of objects)
• null (just empty object)
• str (string in Golang, but operates using runes)
• closures (special type of object, that can be called inline)
