efene programming language

I added the ability to call methods inside structs.

a call to a function inside a struct will pass the struct as first parameter implicitly.

with this we get a behaviour similar to python where methods are just functions that receive an object as first parameter (normally called self).

here are some examples:

@public

present = fn (Self)

    io.format("Hi!, I'm ~s ~s, my email is ~s~n",

        [@Self.firstname, @Self.lastname, @Self.email])



@public

new = fn (Firstname, Lastname, Email)

    New = {

        firstname: Firstname,

        lastname: Lastname,

        email: Email,

        show: fn struct.print:1,

        present: fn present:1}



    New



@public

run = fn ()

    P = new("mariano", "guerra", "foo@bar.com")

    @P.show()

    @P.present()

as you can see, the instantiation of the new struct is similar to javascript.

running the program displays:

<struct firstname="mariano" lastname="guerra" email="foo@bar.com"/>

Hi!, I'm mariano guerra, my email is foo@bar.com

I also added pretty printing of structs in the erlang shell and some more functions to the struct module

>>> P = person.new("mariano", "guerra", "foo@bar.com")

<struct firstname="mariano" lastname="guerra" email="foo@bar.com"/>

>>> @P.firstname

"mariano"

>>> struct.print(P)

<struct firstname="mariano" lastname="guerra" email="foo@bar.com"/>

ok

>>> S = {foo: 1, bar: "asd", baz: true, show: fn struct.print:1}

<struct foo=1 bar="asd" baz=true/>

>>> @S.show()

<struct foo=1 bar="asd" baz=true/>

ok

>>> struct.print(S, true)

<struct foo=1 bar="asd" baz=true show=#Fun<struct.print.1>/>

ok
