Hello,
I am new to ruby and currently trying to operate on each character separately from a base String in ruby. I am using ruby 1.8.6 and would like to do something like:
"ABCDEFG".each_char do|i| puts i end
This produces a undefined method `each_char...

I usually resort to String#split :
"ABCDEFG".split("").each do |i| puts i end
I guess you could also implement it yourself like this:
class String def each_char self.split("").each { |i| yield i } end end
....
I have the same problem.

Hi I am confused .. Are there multiple instances of servlet class? As I hear "each instance of servlet" Can anybody elaborate on this?
Answer Snippets (Read the full thread at stackoverflow):
This leads to two important rules:
don't use instance variables in a servlet, except for application-wide values, most often obtained from context... .
No, there is only one instance of the servlet which is reused for multiple requests from multiple clients .

Both methods appear to produce the same results , but I've been hard-pressed to actually convince people that the second method works, since it's apparently not commonly known.
// Create some data var foo = { 'vals':[ {'id':'foo'}, {'id':'bar'} ] } ; ...

The second $(foo.vals).each makes three function (Not sure how many other function calls....
The first $.each constitutes a single function call to start the iterator.
Between the two is actually exponential depending on how you are using it .

Hi,
As the function accepted by for_each take only one parameter (the element of the vector), I have to define a static int sum = 0 somewhere so that It can be accessed after calling the for_each . I think this is awkward. Any better way to do this (still...

So, something like this:
#include <::for_each(a.begin(), a.end(), ....
For_each returns (a copy of) the functor that it was using.
}
You could emulate std.
To which each element is in turn combined with // for our case must be 0.

The documentation on that page is pretty clear, but in case you need some more help, your PHP snippet will end up looking something like:
global... .
You can use PHP to set specific nodes to redirect to per user .
I'd recommed the Login Destination module.

In case you can't do that for want ever reason, try this:
$("img[id='image']").each.
You the id of each.
each(function(){ alert($(this).attr('name')); });
this in this context is the plain DOM element.

I know I'm missing something here. In the XSLT transformation below, the actual result doesn't match the desired result.
Inside the for-each , I want to apply the match="track" template to each selected track element. If I've understood XSLT properly,...

I guess your

I'd restructure it a little (if you do not need the sorting the for-each approach makes possible to the point, IMHO.

Is there a way to get around the class-loading issues caused by having two enums that reference each other?

Etc } }
for each enum? It looks like you have some overlapping responses in your example.
The issue isn't so much "two enums reference each other", it's more "two enums reference each other Bar.Alpha; // ...
