Re: [Newbies] How to doubble sort a collection

[Raymond Asselin]

I finaly found the problem witch was not in the code suggest but behind the 
keyboard.

In fact when the time is generated everything is good , when i entered it by 
hand = this is a String.
So I had in the sorting code:  
> ^notes sort:[:a :b | (a date = b date) and:[a temps asTime > b temps asTime 
> ]] .

[Newbies] Re: How to doubble sort a collection

[Paul DeBruicker]

Are your temps stored as strings? Strings that are numbers aren't coerced to
numbers before comparison.  

e.g. in a workspace



'765' > '1230'  

prints true and   


765 > 1230 


prints false.

Re: [Newbies] How to doubble sort a collection

[Chris Cunningham]

You have a logic issue with the first one:
sortedNotes
^notes sort:[:a :b | (a date = b date) and:[a temps > b temps]] .
This is saying that the the two dates are different, then false.  For this
you probably want to be something like:
sortedNotes
^notes sort:[:a :b | a date > b date or: [(a date = b date) and:[a temps >
b temps]]] .

[Newbies] Re: How to doubble sort a collection

[Paul DeBruicker]

Proably because you're using #> and not #>=.  If not that post the list of
dates/times that don't sort properly. 



also - #sort: & #sort sort in place.  #sorted & sorted: make a new copy as
you've seen.  If your objects should always sort the same way just implement
#<= in the instance side of your object and then you can use #sort or
#sorted without having to add a sort block.

sounds strange.
Probably you don't want to store date and time separated but as 
DateAndTime instances, then you just have to sort them by that.
Look at that class.
  Also, you can see that Date is a subclass of Timespan,
which implies a duration: a Date is a timespan of one day. You
probably don't want that if you compare them like above.

exactly.
#sorted: is like saying
“Give me this, but sorted” and this “give me” typically results in a 
new collection.
#sort: is like saying
“You! Sort yourself!” and implies mutation
(a bit like set! in scheme or sort! in ruby)

Re: [Newbies] How to doubble sort a collection

[Raymond Asselin]

For now I implemented:

sortedNotes
^notes sort:[:a :b | (a date = b date) and:[a temps > b temps]] .

AND

notesSorted
^notes sort:[:a :b | a date = b date 
ifTrue:[a temps > b temps] 
ifFalse:[a date > b date]] . 

does exactly the same result.

But there is still notes in a same date that do not sort correctly, the 
begining is good and after 5 or so objects
I get some witch do not seem to be sorted.

BTW don't know the difference between sort:  and sorted: 
it seems as if the last one produce a new collection and the first one produce 
same collection but sorted.

Note: I use 24 hours instead of a.m. / p.m. is this may cause problems?

Hi Raymond,

Try:

and: and or: are needed when you don't want to execute the code inside the
block unless it is needed.  They are also used to protect from executing
code that shouldn't be run for example:

x notNil and: [x foo > y foo]

I like this but it may be a little tricky for a beginner.  But both or
replay help one to learn.

I have also attached a file out (from VA Smalltalk) of a class that acts
like a sort block but is much easier to use for complex sorts.

Re: [Newbies] Re: How to doubble sort a collection

[Chris Cunningham]

| and & make sure that each expression between them is executed - so it
will do each of:
   a date  > b date
and
   a date = b date
and
   a date > temps > b date temps

This matters if one of these is significantly slower than the others - it
will run it even it it doesn't need too.  Also if any side-effects are in
one of these expressions, this will make that side effect happen (there
aren't any in these, though).

and: and or: stop executing as soon as one of them is satisfied
sufficiently - so if a date > b date then it will immediately return true
without bothering with the rest of the expressions.
ifTrue:ifFalse: is similar - except you will evaluate the condition
expression AND one of the following expressions.

Often this doesn't matter one way or another - but when it does, it matters
a lot.

Does using the | or & notation have any advantages over and: or or:  or
ifTrue:ifFalse ?


I always write expressions like the one you've written like:

a date = b date 
   ifTrue:[a temps > b temps] 
   ifFalse:[a date > b date]

I have this kind of sorting on anOrderedCollection

BlocNotes >>sortedNotes
^notes sorted:[:a :b | a date  > b date]

This sort my notes on date but I want them sort by date AND inside a date by 
hours and I don't khow how to do this.

Some insights?

If you debug into #roundTo: you'll see its implementation is simple
arithmetic, subject to the vagaries of float resolution.

Float(Number)>>roundTo:
^(self / quantum) rounded * quantum

Now are you wanting something nicely formatted for display, or are you
rounding for some mathematic purpose?  Perhaps instead you are wanting...

   100 * (1.05 raisedTo: 10) printShowingDecimalPlaces: 2  " --> 162.89 "

   0.105 printShowingDecimalPlaces: 2" --> 0.10 "

   0.115 printShowingDecimalPlaces: 2" --> 0.12 "

btw, I only found these today, looking in the printing protocol of Number
and Float.

At first I thought some more parans "(" were needed but that didn't change
anything.  No this sounds like a bug to me (ar at least something that can
be improved) as VA Smalltalk prints 162.89, so somehow they are able to
make the floats do the right thing.

Re: [Newbies] How to round a float?

[Johann Hibschman]

That just looks like floating-point representation. It's as rounded as it
can get!

Re: [Newbies] How to round a float?

[Herbert König]

Hi,


100 * (1.05 raisedTo: 10) roundTo: 0.01 162.890001
  "162.88946267774418" "unrounded"
100 * (1.05 raisedTo: 15) roundTo: 0.01 207.890001
   "207.8928179411367"  "unrounded"


this is to be expected and I think you need a bigger pond than the 
Squeak image to fish for that. I think I found the hint inside Squeak 
only because I know the reason. I think you did your fishing well.


I'll explain later because maybe I can learn better fishing from Ben's 
reply.


Cheers,

Herbert

7 / 8.0 roundTo 0.01 = 0.88  Aha! Thanks!

But:

"162.88946267774418" "unrounded"
100 * (1.05 raisedTo: 15) roundTo: 0.01 207.890001

 "207.8928179411367"  "unrounded"
 Bug, or me again :-)

Re: [Newbies] Panic

[Herbert König]

Hi,

Alt + . (Alt key and simultaneously the . key) usually brings up a 
debugger.


Cheers,

What does one do in Squeak to stop an infinite loop?
If one takes a flying leap at it and:
1) hits anything inside the Smalltalk window nothing happens.
2) hits Ctrl-Alt-Del enough times, selects Task Manger then stops Squeak
then next time it opens it says it can't write to the changes file 
until this is fixed [ok]

Re: [Newbies] How to round a float?

[Ben Coman]

In the interest of teaching how to fish, look at the senders of #roundTo:
to find its usage.

I'll post a full answer tomorrow if you don't beat me to it.
