Hi Squeakers,
Does anyone know of an OrderedSet implementation for Squeak somewhere? Bernhard |

There's that on SqueakSource. ----------------- Benoît St-Jean Yahoo! Messenger: bstjean Twitter: @BenLeChialeux Pinterest: benoitstjean Instagram: Chef_Benito IRC: lamneth Blogue: endormitoire.wordpress.com "A standpoint is an intellectual horizon of radius zero". (A. Einstein)

That link does not work, but there is an OrderedDictionary project on
at http://www.squeaksource.com/TFOrderedDictionary.html. It that it?

Your link doesn't work either. Go to Projects Type OrderedSet in the search box. Only one result will come up (as PharoTaskForces)! If you click on that and browse the versions, you'll see the OrderedSet packages! ----------------- Benoît St-Jean Yahoo!

Thanks Benoit,
The repository is http://www.squeaksource.com/PharoTaskForces, the package is OrderedSet, and the latest version is OrderedSet-StephaneDucasse.2.mcz Dave On Wed, Nov 28, 2018 at 01:06:49AM +0000, Benoit St-Jean via Squeak-dev wrote: > Your link doesn't work either. > Go to ProjectsType OrderedSet in the search box.Only one result will come up (as PharoTaskForces)!If you click on that and browse the versions, you'll see the OrderedSet packages! > > ----------------- > Beno??t St-Jean > Yahoo!

Thanks everyone! That's sounds exactly what I was after. I will give it a try.

That OrderedSet is not really a set, just a thin wrapper over
OrderedCollection, so performance will be surprisingly bad. Squeak has OrderedDictionary which has all the methods a Set needs: #at: anObject put: nil <=> #add: anObject #includesKey: anObject <=> #includes:anObject #keysDo: aBlock <=> #do: aBlock #removeKey: anObject <=> #remove: anObject Note that removal will take O(size) time. If you need anything better, you have to implement your own set (e.g. a linked hash set. Squeak's LRUCache has a list implementation that can come handy). Levente On Tue, 27 Nov 2018, David T.

Never really looked at how it was implemented for that specific package... But then, one might ask (which is my case), do you really need an ordered set? I never had in 26 years of smalltalking! ----------------- Benoît St-Jean Yahoo!

I used Stack just a few weeks ago. I didn't even know it was a class before I needed it. :-) Cheers, Karl On Wed, Nov 28, 2018 at 7:48 PM Benoit St-Jean via Squeak-dev <[hidden email]> wrote:

That depends on what is meant by 'ordered'. Whenever I wanted an Ordered thing (usually Dictionary, never yet Set) what I really wanted was the order in which the elements (or keys) were added. aBag sortedElements is more like a SortedSet. -cbc On Wed, Nov 28, 2018 at 1:41 PM Ron Teitelbaum <[hidden email]> wrote:

Hi Levente,
I like that idea! Performance is a non-issue for my use case. I don't even have the need to remove elements. Are there any objections to include OrderedSet as a trivial subclass of OrderedDictionary to Squeak? I have looked at the list implementation used in LRUCache. I love the terseness of the code. I wonder why you did not call it CircularDoublyLinkedList to make it easier to find for other uses?
