The Future of Ruby

Yukihiro Matsumoto's C implementation of Ruby aka Main Ruby Implementation is considered the Quasi-Standard of the Ruby Language since there has never been an explicit language standard for Ruby. As the number of implementations grows, however, a formal standard seems to become necessary to prevent the horror scenario of various non-conform interpreters. Read on ...

Extending Ruby in C

Extending Ruby with C functions is quiet easy. After you have learned the principles and worked through the ambiguous usage of the API functions you get the power of the Ruby language to your C program. Then it is possible to solve the time critical tasks at the C program and the complex part by Ruby. We created a simple tutorial to get quickly familiar with the Ruby C extension API.

Threading is now implemented native. But there is a major drawback with the Ruby interpreter implementation. Many global's are used. As a result the interpreter cannot be run more than once at a process. As an example, the LUA interpreter does this perfect. The interpreter can run at several instances, each instance using a pointer to the interpreter context.   Read Ruby/Ruby V1.9 C Extension ...
