Well, we can say "concepts" in place of "theory". And I'm comparing Eiffel with other OOP lang, not with some langs based on a solid math theory (lambda calcules for FP langs, for example). ok? DbC is not the same as "assert macros". First, it has a lang semantic. There is an interesting
Opps... I forgot about Eiffel agents! PS. After participationing in this discussion I'm tempting to reread Meyer's book after 10 years interval, to have a detailed look at the eiffel from the FP position. When I read this book first I know nothing about FP.
Eiffel, for my opinion, is a best OOP language. Meyer use a theoretical approach as it is possible in OOP. 01.01.2013, 23:56, "Bob Hutchison" hutch-li...@recursive.ca:On 2012-12-31, at 4:26 PM, Rico Moorman rico.moor...@gmail.com wrote:Hello Bob and Mike, Reading a little within the suggested book

Hello, haskellers.
Suppose we have this xml doc (maybe, little stupid):
div
spanSome story/span
spanDescription/span: This story about...
spanAuthor/span: Tom Smith
/div
In the end I whant to get list: [(Title, Some story), (Description,This
story about...), (Author, Tom Smith)],

I absolutly agree with you but unfortunetly, it is not my xml file.It is extraction from html page of public web server. I cannot to change format of this html page.Sorry. I had to explain it in first letter. But than what about to get sibling text (geting sibling is an separate interesting tasks
, Student B-TI)
w.g.g.vanas...@student.utwente.nl:
You might want to check out the xml-conduit package. It has preceding
and following sibling Axis. I am not sure how the package works
exactly, but it seems to be a good starting point.

Maybe everytime you use 'cell' you tell haskell to create NEW cell.
Try this:
push' i cell = modifyIORef cell (++ [i])
main = do
cell - newIORef []
push' x cell {- push' 3 cell will be incorrect in this case -}
push' o cell
readIORef cell = return
Why the original code porduces

Haskell does not and cannot know what the result of an IO action is, because
it's outside the scope of the language (and computation). (The Int part of
IO Int refers to the input, not the output; it's just a sort of type
Of course we take in matter what computation getStr :: IO [Char] means.
Of course we take in matter what computation putStr :: String - IO () means
(I know, putStr is not computation, puStr x is computation, but it's not
important)
And If I want to write echo program, I have to combine these
If seed depends of psudo random event, for example of current systime,
we must use IO action.

BTW - why use an IO action for random number generation? There's a
perfectly good pure generator. It's probably handy to treat it

Are formlets integrated with HSP?
hsp support is in a separate package:
http://hackage.haskell.org/package/formlets-hsp
There is a demo of using HSP+Formlets+Happstack here:

Well. Thanks. I've just have a look at formlets. I think is what i need.
But I'm using now HSP. Are formlets integrated
