Now I have tried the below : C:\>irb --simple-prompt >> class Foo >> def initialize(x,y,z) >> @x, @y, @z= x, y,z >> end >> def to_hash >> [@x => @y] >> end >> end => nil >> foo=Foo.new(10,11,12) => #<Foo:0x11f8968 @x=10, @y=11, @z=12> >> a,*b=foo => #<Foo:0x11f8968 @x=10, @y=11, @z=12> >> a => #<Foo:0x11f8968 @x=10, @y=11, @z=12> >> b => [] >> Here the results are not same as with the above. So is it calling my first instance method automatically? Couldn't understand the logic.

WHY do you think that? why you dont get the IDEA that it MAYBE calls to_ary? becaue *arg is the Splat Operator that parts Arrays into members, and MAYBE it calls to_ary is the object is not an Array?

Ok, understood what the guy wants ...
"Love U Ruby" is a troll trying to steal time.
See his other "posts".
If his original question would have been solely
about * then he would not have had the need to
write such awful code to pseudo-legitimize his
question.
I mean, he *must* know ruby because he purposely
returns an Array, and calls the method to_hash:
def to_hash
[@x => @y]
end
WTF?!?!
To the guy behind "Love U Ruby", please - go grow
up, find a job, then you won't have a need to go
trolling for reactions.

Really never thought about to "steal" your time, no intention of that. I just asked you guys as you are expert. Just give me a tips or trick ... That's enough, I will dig into that. Please don't tell that way;You are educated on this, thus asked. And another person also trying to be fit on your domain, Is it bad? You should be proud by thinking that - what you love,others too. If anyone incomplete, please try or at-least give him/her something so that he can be strong. We should share our knowledge - that's why the forum built,to keep you and like me, or you like you people come close and help each other. > I mean, he *must* know ruby because he purposely > returns an Array, and calls the method to_hash: > > def to_hash > [@x => @y] > end > > WTF?!?! > > To the guy behind "Love U Ruby", please - go grow > up, find a job, then you won't have a need to go > trolling for reactions.

It's all about the perception... depends on people mentality. Forum is to help someone. I would agree with Robert, although not with you. You people have time to browse through these links but when someone would ask something - you are saying "NOT TO WASTE YOUR TIME". you know my name.. right? so any post with my name please ignore.. Please don't spread such bad things over all. Remember you also passed such days when you were junior to ruby...

Firstly this is not a forum but a mailing list.
Second we do not come here to help people, we come here because we are
members of a community. We help people because we feel like it not
because
we have a duty to.
You are right about one thing though, it is all about perception. Why do
you think people call you help vampire?

Leave it. Answering such cheap things seems to me really time wastage. "And be remember - a just brown tree welcomes people who are giving water at it's root, but never disrespect who are not." ~~~ First time I am seeing this community such bad mentalities of people. It seems I am asking money from their accounts. I am asking to share their tips if any, but ........ have no words. Thanks

If I spend money I can just earn some more, the time I spend here is lost when it passes. I commute 5 hours a day, I work 8 hours a day, I sleep 7 hours a day. Do the maths Just replying to this post will take around 10 to 15 minutes as I stop, rewrite, reedit, reread repeatedly. Just because we give freely does not mean it is worthless and it is certainly not cheap.

Then how should I call "Google" who keep sharing the knowledge to everyone "FREE", how would you consider "YouTube" who does the same job. How would you consider the the man : "David A. Black" writer of "The Well-Grounded Ruby". Go to the link: and see how is he redelivering all his speech what he already mentioned in his book and "YouTube" giving us it FREE : http://www.youtube.com/watch?v=Xt6c6r4fbBs So in simple sentence it is depends upon people mentality, who felt disturbed when he shouldn't but he can obviously. But in such a case don't need to be keep shouting. If you love to share knowledge share it,otherwise keep quite. Don't try to assemble a group of like you. Its not about help,not about money, only about dedications... then you don't have. --- Thanks

This whole exchange reminds of this quote: I went to a bookstore and asked the saleswoman, "Where's the self-help section?" She said if she told me, it would defeat the purpose. Anyway, consider this line of reasoning: 1) Do not feed the trolls. 2) Goto 1

Then you would never have to ever see them. I'm sure that such facilities exist in most software (unless you are reading this on a forum, in which case you will have to find out for yourself). If my posts were causing you such grief then surely you would have done this already. But then you would miss out on me giving you this useful advice :)

when we write the "range" with splat(*) generally got the array as below: >> a = *(2..5) => [2, 3, 4, 5] But in the previous case why I got [2, 3, 4, 5] not [[2, 3, 4, 5]] >> a = [*(2..5)] => [2, 3, 4, 5] >> here and there concept in Ruby.... Huuhh ;-)

On 25 February 2013 02:24, Love U Ruby <lists@ruby-forum.com> wrote: > > here and there concept in Ruby.... Huuhh ;-) This is a legitimate question. As we've seen, on the splitting side (i.e. the RHS of an assignment, if any) the splat operator attempts to convert an object into an array, pretty sure it does it by calling that object's to_a method. Thus the following would be functionally identical: a = *(2..5) a = (2..5).to_a However it does more than that. The splitting side of splat can splice the splatted value into an array, for example: a = [1, *(2..3), 4] # => a = [1,2,3,4] By paring that down and removing the 1 and 4, you can see why: a = [ *(2..3) ] # => a = [2,3] It splices the splatted range into the existing (anonymous) array. If you want it to be nested inside, you have to explicitly call `(2..3).to_a` instead.
