BTW: This would be SortedCollection, not OrderedCollection or its superclass. Still I am not convinced that I really need an implementation of #< in SequencableCollection. Too many ways to interpret what greater or equal or lower could mean...

I'd say it is questonable if SequenceableCollections should be comparable by default. is (a b c) equal or lower than (b a c) ? Doesn't this depend heavily on what is in the Collection and what the meaning of the Sequence of two Collections is? So I'd say there is not much use in putting comparisons into the base class library, because there is a ton of assumptions about the Collections in whatever implementation one can imagine. I would assume that this is the job of some business object that holds objects in a SequenceableCollection. Don't you think? The fact that other languages provide such an implementation doesn't mean much to me, to be honest. I choose a SequencableCollection in order to keep objects in a certain order, nothing more, nothing less. I think it is important to not get "overridden" by the fact that something is extremely easy to do in Smalltalk. We can easily make bad mistakes, just because we can.

Comparison for SequencableCollection

by webwarrior

I was surprised when discovered that in Pharo comparison is not defined for lists, arrays and similar datastructures. Because in almost every programming language (F#, Python, Javascript just to name few) you can compare lists, arrays, etc. By convention, the ordering is lexicographical, just like in strings. It took little time to add needed methods to SequencableCollection, but I think its better to have them in core library (core image, or how do you call it?). -- View this message in context: http://forum.world.st/Comparison-for-SequencableCollection-tp4840704.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

It looks like I need some guidance to understand contemporary packaging/deployment/versioning system. I know it exists, but I don't know details. Can you kick me in the right direction?

I'm in active development/improvement of this importer just now. So just be sure that you checked comments to the releases uploaded before actually using it. 2015-08-02 11:07 GMT+03:00 Ben Coman <btc(a)openinworld.com>: > Cool.

Re: [Pharo-users] Create maps from an SVG file in Roassal

by Alexandre Bergel

Yes, it would be great! I first tried to understand the SVG parser in Athens, but I could not make it to work. So I wrote the one in Roassal. But indeed, we need a better thing. By the way, there is no parser supported by Cairo?

Hmm, maybe Athens-SVG will not be so simple, because it's paint-only so I would still have to write a lot of stuff around. But maybe we could grab the SVG path lexer that's there (and is better than in Roassal) and use it to simplify and improve current implementation, so even multi-coordinate commands work. I shall investigate more...

Tabular: XLSX import

by Ð®ÑÐ¸Ð¹ ÐÐ¸ÑÐ¾Ð½ÐµÐ½ÐºÐ¾

Hello. Some time ago I announced Tabular <http://ss3.gemtalksystems.com/ss/Tabular.html>, some effort to make a tool for spreadsheets import/export. This is short notice: Vincent Blondeau have added XLSX import functionality! It's also mostly proof-of-concept now, but even at this stage it's quite usable. Thanks, Vincent!
