how to add a method_missing method into ActiveRecord

229393 [thomasmuelle] I need to add a CDATA element to an XML document.
229406 [rosco@ro co ] Wow, that's a fairly old version you have there :)

How to overload the operator !=?
229395 [ankyhe@gm il] I overload ==, >, <, >=, <=successfully, however I can't overload != .
+ 229396 [dudu@du u. o] Overloading "==" should do it :)
| 229429 [jan.svitok@g] != is a defined using == i.e. a != b is parsed as !(a == b)
| 229445 [dudu@du u. o] Which is precisely what I meant :)
| 229458 [jan.svitok@g] Right, I just though some clarification would not harm ;-) I should've
+ 229501 [pubsub@ru yi] The != token is not really a method at all and thus cannot be redefined.
  229524 [shortcutter@] It's been a long day and I'm not sure whether my logic fails me here,

Restricted capture in Regexp
229397 [benjohn@fy h] Is there a regexp feature that lets me require something to be present
+ 229400 [nospam@no it] Neither yes nor no, because of how you have worded your question. Se below.
| 229404 [benjohn@fy h] thanks for the reply. I know I can do this, but it means that the
| 229410 [nospam@no it] / ...
| 229421 [benjohn@fy h] I think this may be what I should use. Also, the sugestion of using word

| + 229450 [neoneye@gm i] In a language like ruby, its not possible to distinguish between
| + 229483 [nospam@no it] Again, your prose description is not precise enough for a reader to know
|   229693 [benjohn@fy h] I was able to. I had not understood that scan and gsub work
|   229698 [nospam@no it] result = "axb".gsub(/(.)(x)(.)/, "A\\2B" ) # gets what you want.
|   229768 [Rob@Ag le on] If you're not interested in the other groupings you can use (?:) to
+ 229402 [lists@be tr ] /\b[xy]\b/
| 229407 [benjohn@fy h] This seems like the best approach in this case, as it's a good enough

How to improve my Ruby skills ?

  229414 [siddharth.ka] Thanks Peter.

Is there a class that is equivalent to Properties in Java
229425 [dou_yifan@ya] Is there a class in the ruby lib that is equivalent to Properties class
+ 229437 [shortcutter@] Hash.
+ 229447 [twifkak@co c] If you can read something that can parse and emit Java .properties
+ 229451 [james@gr yp ] I think the following code should cover most of the Properties class

Hpricot html parsing

    230326 [eduardo.yane] Thanks a lot to Francis and David, finally I got it. Since I don't have an administration account,
    230380 [garbagecat10] David's points are quite true, however the Net::LDAP#bind_as method is
    230394 [eduardo.yane] and it worked right. What I don't understand is why whether you try to 'bind_as'

map taking an argument (was: Re: join_with)
229469 [dblack@wo bl] Your point about map re-raised a question that was in my head
+ 229482 [djberg96@gm ] Good question.  One guess is that they wanted a more generic approach,
+ 229485 [ara.t.howard] i think that makes good sense considering ruby's pattern of not auto-magically
| 229496 [djberg96@gm ] I doubt it.  My feeling, based on the posts I've seen on the topic over
| 229497 [dblack@wo bl] I hope you're right.  I dislike it not only for its line-noise
+ 229492 [dblack@wo bl] I screwed up my procmailrc briefly and lost a couple of messages.  So
| 229502 [ara.t.howard] in both cases the arguments types changes the semantics of the method.  in one

|   + 229526 [james@gr yp ] Does the version currently in Ruby 1.9 support arguments?
|   | 229540 [dblack@wo bl] I don't think so.  I'm actually not sure where they'd go, since &:meth

How to always write Windows style newlines to a file?
229477 [weyus@at .n ] I need to write a CSV file and I know that I always want Windows style
