Cibyl, a lightweight curly-bracket language which compiles to Ruby and Crystal

Cibyl allows to use a C-like syntax for Ruby and Crystal applications :

// Recursive Fibonacci function

def fibonacci(
    n : Int32
    )
{
    if ( n <= 1 )
    {
        return 1;
    }
    else
    {
        return fibonacci( n - 1 ) + fibonacci( n - 2 );
    }
}

puts fibonacci( 5 );

It also allows to replace keywords, and to use a different case convention :

require "http/server";

server = HTTP::SERVER.New
    do |context|
    {
        context.Response.ContentType = "text/plain";
        context.Response.Print( "Hello world! The time is #{TIME.Now}" );
    }

address = server.BindTcp( 8080 );
Puts( "Listening on http://#{address}" );
server.Listen();

Obviously, Cibyl is NOT intended for the typical Ruby/Crystal lover. Its primary goal is to allow those who find a curly-bracket language syntax more pleasant to their eyes, to not disregard Ruby or Crystal just because of their syntactic preferences…
