[Pharo-project] copying formatted text into a Pages (or any)

by Esteban Lorenzano

Hi, Is there a way to copy formated text inside a Pages document (or any other external writer) ? Cheers, Esteban

Re: [Pharo-project] XTream was Re: Re: Ocean (was Re: Less plugins, more Smalltalk code!)

by Schwab,Wilhelm K

Stef, Do you have any interest in my alternate protocol idea? In short, #next is misleading even on VW. When I learned that, I pretty much gave up on a robust implementation and did the logical thing: made the alternate selectors and started writing all of my new code in terms of them. It is a lot quicker to type a few extra characters than to spend a lot of time chasing down side effects rather than original errors. By simply making new code work better, the backward compatibility problem largely evaporates. It's a shame that perfectly good selectors #next and #next: are usurped, but that's how it is unless we want to break a lot of old code. One interesting observation (not mine) is that many #next and #next: senders in the image are vulnerable to defects if they get other than expected results. Robust semantics would break some things, but call attention to lurking bugs elsewhere. I will happily make the alternate selector code available if you want it; in fact, an old version is in the in box. In the past, you expressed concerns about getting exhaustion errors when you don't want them. My answer is that #nextAvailable: exists for that purpose - it "authorizes" truncation. You can also add a #nextOrNil if you must (I might even have it for benefit of some of my older code). In Pharo, #nextOrNil is trivial: just delegate to #next.

Re: [Pharo-project] XTream was Re: Re: Ocean (was Re: Less plugins, more Smalltalk code!)

by Nicolas Cellier

Yes, every time I must warn and apologize because I'm guilty of hijacking the name. The goals are more or less the same, because I also hijacked some ideas (though not all invented at VW): - separate read/write stream - use stream wrappers - implement main sequenceable collection API (more to be found at http://www.squeaksource.com/XTream.html wiki page) There are also Squeak specific goals: - clean the mess by first principles (just an excerpt http://lists.squeakfoundation.org/pipermail/squeak-dev/2009-December/141786… ) - accelerate MultiByteFileStream At time Squeak Xtream started, there was no license for VW Xtream, so it's a full rewrite from scratch. Thus implementation differs. Mainly I did not reify the Buffer (the master piece of original VW Xtream). Due to this, I've got a BufferedReadWriteStream, which is contradictory to goal 1). It might change in future. I also do not want to depend too much on Exception handling, which current VW Buffer implementation does. Also, I did not replace the whole protocol, but rather reused existing one. That's because further goal is to provide a replacement for Squeak Streams (could apply to Pharo too, but there's a possible overlap with Nile* See note below). However, I currently made no plan to reach this goal. I just have some toy images that I break regularly due to lack of compatibility... Either I implement all the messy protocol that flourished in Squeak, or I try to stay a bit cleaner but with uncompatibilities... Maybe a separate compatibility package with a deprecation policy might help... Be aware that recent Squeak and Pharo acceleration thanks to buffering was first experimented in Squeak Xtream, and then ported by talents of Levente, that's already a little reward. Some big acceleration could be gained other UTF8 streams when a majority of characters are ASCII (the case of source code management and most latin characters texts), both in cog and traditional vm. My current tests (cog) are: { [| tmp | tmp := (MultiByteFileStream readOnlyFileNamed: (SourceFiles at: 2) name) ascii; wantsLineEndConversion: false; converter: UTF8TextConverter new. 1 to: 20000 do: [:i | tmp upTo: Character cr]. tmp close] timeToRun. [| tmp | tmp := ((StandardFileStream readOnlyFileNamed: (SourceFiles at: 2) name) readXtream binary buffered ~> UTF8Decoder) buffered. 1 to: 20000 do: [:i | tmp upTo: Character cr]. tmp close] timeToRun. } #(163 21) So, Xtream is around 8x faster at reading first 20000 lines of change log... No surprise it's more than 99% pure ASCII. Last, concerning the errors, it's more a matter of fixing the tests themselves... They use #squeakToUtf8 as a reference, and some tests are for other unloaded XTream packages. I started to change the test last night but did not publish all... See also: http://lists.squeakfoundation.org/pipermail/squeak-dev/2010-September/15357… http://lists.squeakfoundation.org/pipermail/squeak-dev/2009-December/141539… http://lists.squeakfoundation.org/pipermail/squeak-dev/2009-December/141647… and more mails in november/december 2009 more dated material http://bugs.squeak.org/view.php?id=6755 and various attempts like LazyStream/LazyCollections... Nicolas * Note about Nile: Nile has a different approach: do not eliminate ReadWriteStreams, but compose with traits. Nile also has high test coverage level, which is good. Nile was designed as a Stream replacement for Squeak Stream... As such, it carries some cruft (same dilemna as Squeak Xtream). Pharo goal is to perform major clean-up. As a mean to reach this goal, it shall not encumber with backward compatibility. This means that once Nile adopted (with historical compatibility cruft), it should be cleaned up again... 2010/10/7 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr>: > pay attention that there are two xtreams package frameworks from what I understand > > Â Â Â Â one presented at esug and one developed by nicolas > > Stef > > On Oct 7, 2010, at 4:58 PM, Sven Van Caekenberghe wrote: > >> >> On 06 Oct 2010, at 08:48, Nicolas Cellier wrote: >> >>> See also hijacked Â http://www.squeaksource.com/XTream.html borrowing >>> some of the ideas, but somehow less extreme. >>> Most packages should now load in Pharo. >> >> Hi Nicolas, >> >> I have been looking at the ESUG 2010 slides & google code project pages of xstreams and I must say that I like this very much. >> >> Your code on SS does indeed load in Pharo 1.1. 8 tests fail out of 37 with errors that I think are probably fixable.
