众ruby宝石璀璨， xruby 昏暗未卜

最近都在忙另外的事情，这几个月都没怎么动xruby了。几个星期前和chad fowler碰到过。他是早于tom，charles他们做jruby的人，他做到了支持test::unit完后基本就放置了。过了一段有tom，charles加入，成功的marketing后把一个基本废弃的项目挽救了过来。

xruby如果没有新的有热情的成员加入的话，肯定就会荒废了。

主要没有看到远景和愿景规划

也没有看到有采用的实际例子，如尽快能与其它ruby框架支持，rails 或merb等就有发展了

mod rails还有ironruby都以华裔主导的开发者为ruby添光加彩，xruby更应保持起初的激情，再创辉煌

以下给ruby底层的有志青年看，5.4不放假的看看也罢

用ruby写compiler系列

出到第五个

http://www.hokstad.com/writing-a-compiler-in-ruby-bottom-up-step-5.html

xruby真的很可惜，当初jruby还只有interpreter, 现在jruby也有compiler了。

yawl是xruby的作者？当初看到你去了thoughtworks还以为tw要力挺xruby了。。sigh

从底下往上的方式写compiler 陆续还有20集的连续剧

Upcoming parts

These are the almost ready pre-written parts only. I expect once I need to start catching up on new parts the focus will be on a simple parser with the goal of making the compiler self-hosted (i.e. able to compile itself) as quickly as possible.

* Step 4: Introducing a runtime, and defining functions
* Step 5: Handle literals other than strings
* Step 6: If ... then ... else
* Step 7: Looping constructs
* Step 8: Anonymous functions (lambda)
* Step 9: Revisiting loops with anonymous functions, accessing function arguments
* Step 10: Adding assignment and basic arithmetic
* Step 11: A cleaner "while" loop
* Step 12: Testing the language: Writing a simple text mangling program to make input cleaner
* Step 13: Refactoring the code generation and starting to abstract out the target architecture
* Step 14: Discussion of various concepts and future direction
* Step 15: Adding arrays
* Step 16: Local variables and multiple scopes
* Step 17: Accessing variable length arguments
* Step 18: Revisiting the text mangler - cleanups to test new functionality, and run it on itself
* Step 19: Identifying the constructs needed to self host the compiler
* Step 20: A start on a proper parser

MagLev 仔细看，原来是“磁悬浮”

Gemstone （做seaside的）builds Ruby runtime based on Smalltalk VM
