E# is an object-oriented programming language for embedding, created by Adrian Punga in 2012. E# is mainly based on ideas in SmallTalk, Python, Java and C# but it resembles the syntax of Java. E# combines message-based computation with Java-like syntax.

Philosophy

E# is an effort to create a programming language suitable for being embedded in various applications on various platforms. It aims to have a flexible architecture and a clean syntax while keeping the total size of the language under 1MB. E# is fully object oriented (anything is an object) with pure encapsulation (only private properties) and uses message passing to connect code actions.

Syntax and examples

E#'s syntax is most similar to Java, though it also bears some resemblance to Python and C#. Here is an extremely simple E# program:

stdout.println("Hello, world!")

Another more complex example is a class definition:

class D {
        readwrite a = 2.7182818311111;
        readonly b = 2.71828183;
        writeonly c = 1.3806504e-23;
        d = 3.14159265;
        printme(con) {
"""none <- D.printme(console <c>)
        Prints all the properties for class D to console <c>.
"""
                con.println("a=",a);
                con.println("b=",b);
                con.println("c=",c);
                con.println("d=",d);
        }
}
