Now, we're tasked with converting this into bytecode for RubyEx, keeping consideration of the entire object model. How do we handle the creation of classes, for instance? Or defining functions? We need to be aware of our “context”, which is this strange main Object. MRI uses an i…text/html2008-04-19T04:08:51+00:00dev:eval - context, link to :start

Problem with package:module
If source-code contains an eval-like statement (which it probably will - this is Ruby), then RubyEx's module has no method for decoding it. Probably, translator would either need to be called in user-space from kernel-space (ouch!), or perhaps translator can also be loaded into the kernel.text/html2008-04-19T04:07:10+00:00package:program - created

Synopsis
The Program package of RubyEx is a C++ VM which accepts byte-code generated from the translator and evaluates it.
Interface
Program accepts bytecode on stdin by default, and evaluates the bytecode in the context of a RubyEnvironment (more-or-less equivalent to a cell in module).text/html2008-04-19T04:03:12+00:00start - Adding github link.

Synopsis
RubyEx is a parser, byte-code compiler and interpreter for the programming language Ruby.
You can track/fork the source code on Github.
Its progress is documented in English and Japanese (日本語) on my blog, and here.
Target
RubyEx consists of a few packages at current:text/html2008-04-17T12:16:24+00:00dev:objectmodel - created

Synopsis
The module package of RubyEx is a C kernel module which accepts byte-code generated from the translator and evaluates it.
Interface
This package's interface is exposed by character devices.
Developers
It registers a chardev and outputs the major to dmesg. Minor 0 is used for communications, and it supports a fairly simple command language, supporting the registration of cells. Each cell is a Ruby execution environment/ObjectSpace, and is associated with a name and minor. Byte-code…text/html2008-02-21T08:41:16+00:00Arlen Christian Mart Cusspackage:translator - created
http://rubyex.sairyx.org/package:translator?rev=1203583276&do=diff
Synopsis
The translator package of RubyEx is a C++ Bison/Flex parser written from scratch. It constructs an AST and emits byte-code (there is relevant discussion on byte-code).
Support
This package attempts to parse Ruby source-code in a manner as compatible with the official Ruby implementation as possible, targetting 1.8, with some of 1.9's features. It is barely complete, though the framework is completely set up, and relatively complex constructs are parsed correctly.
