## Builtin module
|
|
|
|
The Builtin module contains functions that can not be coded in ruby.
|
|
It is the other side of the parfait coin, part of the runtime.
|
|
|
|
The functions are organised by their respective classes and get loaded in boot_classes! ,
|
|
right at the start. (see register/boot.rb)
|
|
|
|
These functions return their code, ie a Parfait::TypedMethod with a MethodSource object,
|
|
which can then be called by ruby code as if it were a "normal" function.
|
|
|
|
A normal ruby function is one that is parsed and transformed to code. But not all
|
|
functionality can be written in ruby, one of those chicken and egg things.
|
|
C uses Assembler in this situation, we use Builtin functions.
|
|
|
|
Slightly more here : http://ruby-x.org/2014/06/10/more-clarity.html (then still called Kernel)
|
|
|
|
The Builtin module is scattered into several files, but that is just so the file
|
|
doesn't get too long.
