DESCRIPTION:¶ ↑

Wilson is a pure ruby x86 assembler. No, really. Worst Idea Evar.

Why “wilson”? I wanted to name it “metal”, but there is an existing project with that name… So I'm naming it after Wilson Bilkovich, who is about as metal as you can get (and it is easier to spell than “bilkovich”, even tho that sounds more metal).

FEATURES/PROBLEMS:¶ ↑

• Generates x86 machine code directly. No dependencies. No system calls.

• Registers ruby methods with defasm, or run inline assembly with asm.

• Terrible, yet, awesome.

SYNOPSIS:¶ ↑

class X
  defasm :superfast_meaning_of_life do
    eax.mov 42
    to_ruby eax # ruby fixnums = (n << 1) + 1
  end

  def inline_asm_example
    n = 1000

    asm :count_to_n do
      eax.xor eax
      count = self.label
      eax.inc
      eax.cmp n
      jne count

      to_ruby eax
    end
  end
end

p X.new.superfast_meaning_of_life # => 42
p X.new.inline_asm_example        # => 1000
