class Sys

core :: Sys

The main class of the program.

Sys is a singleton class, its only instance is accessible from everywhere with sys.

Because of this, methods that should be accessible from everywhere, like print or exit, are defined in Sys. Moreover, unless there is an ambiguity with self, the receiver of a call to these methods is implicitly sys. Basically it means that the two following instructions are equivalent.

print "Hello World"
sys.print "Hello World"

Methods Implicitly Defined in Sys

Sys is the class where are defined top-level methods, i.e. those defined outside of any class like in a procedural language. Basically it means that

redef class Sys
   fun foo do print "hello"
end

is equivalent with

fun foo print "hello"

As a corollary, in a top-level method, self (the current receiver) is always sys.
