Compiling Ruby to Binary.

Putting wings on ruby to let you fly (may take X years).


RubyX compiles ruby code to binary.
In 100% pure ruby.

The goal here is to prove that dynamic languages do not have to be slow.
Only interpretation is slow, but when ruby is compiled to binary ,it can be really fast.

How fast (X times), will eventually depend on the community. The RubyX approach works, but to create an mri compatible ruby will take many more man-years than i have.

RubyX is here to empower you, to make your ruby shine as much as you like.


The RubyX compiler is working (ie creates binaries), and the architecture has been refined over several years.

A substantial part of the ruby language has been implemented:

Upcoming work

But there is still a lot of work, here are just the next few topics

  • Dynamic Memory management
  • Benchmarks for calling and integer
  • Start stdlib with String and files
By then we may be in the foothills, but nowhere near even basecamp, let alone there.


The short introduction is under the architecture menu.

The presentation for GrillRb is more detailed than the previous unconf Hamburg one. But a 20min video was made in hamburg and can be found on youtube

To get to know the system, there is also an interpreter and a basic visual debugger.

The about section has some info of when and how this started. If you feel like contributing read this or write a mail to the group.


Last but not least, i try to get recent developments down on paper when they are still fresh.
