langX

It's a script language. I made it for quick developing.

It's in developing stage.

Features

• Weak typing, interpreted script language.
• Easy rules.
• Bridge other languages library.
• The last user have power to change the library's behavior.
• No private keyword, field and variable are public.

Use Atom as editor.

langX-atom plugin, it's used for syntax highlighting, and it works in progress. And it do not support auto-complete.

Simple code example

// a.lx
// this is the comment.

// this is the function.
funa => {
	a = 1 ;
	funb();

	// build-in function.
	println("funa" + a);
}

funb => {
  println("funb: " + a);
  a = 101 ;
}

// call function
funa();

// b.lx

// declare class
Student {

  // class member
  name;
  age = 20 ;

  // class function
  a => { print("hello,a!\n");}

  printInfo => (a3){ print("name: " + name + "\n");  print("age: " + age + "\n" ); print("a3: " + a3 + "\n");}

}

// new a object
s2 = new Student();
s1 = s2;

// set class prop
s1.age = 10 ;
s1.name = "Mr.Ming";
b = s2.age;
c = s2.name;
/*print("b: " + b + "\n");
//print("c: " + c + "\n");  */

s1.a();
s1.printInfo("ahahahah~");
