A routine which can breakdown a string and return the results in an array or a routine that can parse an .ini file and return the key value pairs in an array[key]=value. Require, load and include --- what's the difference?.

Mixins are Ruby’s version of multiple inheritance: whereas C++ authorize multiple parents for classes, Ruby forbids this, but provides a mechanism for classes that share common capabilities to share code as well. Let’s make this more explicit: Array is a descendant of Object, as are all Ruby classes. Another key aspect involves, hash is also a descendant of Object. Ruby's simple_format method is not working for spaces. so how to add and what to add in simple format method code so it also work for spaces?

In relation to this, ruby's "case" doesn't behave like a normal switch. Ruby’s case - and I think that’s a good thing. To make breaks necessary to break out of a case clause (and creating the danger for programmers to incidentally forget one), was probably one of the most inane ideas of the C language’s creators.

From another angle, yeah – this is a feature which you might not recognize as such because you’re used to the bug. Ruby's "More than one way to do things." - Ruby - Ruby-Forum.

IronRuby's Marshal.dump doesn't work with CLR types, or ruby types .... For dealing with Clr-backed objects such as Exception should we just create special cases in the Marshal to dump and load them? Is there any way I can find out what other ruby objects are actually CLR objects other than Exception types and the basic int, double, float types? My experiments with extending the marshal to dump CLR types were interesting.

I can dump and load pure CLR types such as ... Passing a named function instead of a code block? Hello, I have a question about ruby’s feature that when you call a method, you can pass in a block of code after the last argument. Instead of writing a code block, suppose I already have a def’d method that would wor…
