Re: [Pharo-users] portable smalltalk, how ?

by Igor Stasenko

My 2 cents. It depends, what sense you put into portability. SqueakNOS can run on any intel-based architecture. But you don't have OS and need to implement all low-level stuff by yourself. No matter what software, I think you can claim that it is portable only to certain degree. To my opinion, it is better to have software which runs perfectly on some concrete platform, rather than have buggy/incomplete and with limited feature set (because of minimum common denominator) software which runs everywhere. Apple's success with IOS platform is a good showcase for that. An opposite example is web "platform". Despite the great progress in last decade, it is still far behind from desktop-based software in terms of responsiveness, speed and resource usage. -- Best regards, Igor Stasenko.

Janko, I have not looked it in more depth for quite some time, but where is the best place to look to learn the API that Sport provides? (especially for someone who does not have in depth knowledge and access to VW api)? Thanks! Davorin Rusevljan http://www.cloud208.com/

Sockets on wrong abstraction level? Which abstraction level is then a right one? Only questionable thing is that Sport API is influenced strongly on VisualWorks. But this is hard characterize simply as wrong. In any case, Sport is so far most successful attempt to make portable Times, Files, and Sockets. Specially last two are very different from dialects and Sport enables easy portability of projects like Swazoo web server and Aida web framework. When Sport is ported to some dialect, all other projects based on Sport became portable there almost instantly. Another reason is also that both Swazoo and Aida are written with portability in mind by avoiding non-portable dialect features and libraries and therefore don't need Grease for that, just Sport. Remaining dialect dependencies are marked simply by method comment, like "VW specific". End result is very simple code, yet maintainable and portable. Sport is supported on GNU Smalltalk, VA Smalltalk, Squeak/Pharo, VisualWorks/ObjectStudio, Dolphin Smalltalk. News from this year ESUG Edinburg: Sport will become MIT licensed, now is namely GPL. I therefore invite specially network/web guys to write more portable code using Sport and therefore spread your work around all Smalltalks.

You need the builder from Lucas: https://github.com/renggli/builder The main page also provides a detailed set of instructions.

How can I run my own CI server?

by Pat Maddox

I'd like to set up continuous integration for my own Pharo projects. Does anyone have pointers on setting one up? Some basic pointers on how to build an image and run the tests from scratch (ideally headless) would be very helpful. Thanks, Pat

Morph added to World event

Is there any notification (event/Announcement/etc) when a Morph is opened in the World? Thanks. Sean -- View this message in context: http://forum.world.st/Morph-added-to-World-event-tp4144928p4144928.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] portable smalltalk, how ?

by Lukas Renggli

For UI portability the only way to go is to have a clean separation between model and view. OmniBrowser, Glamour, ToolBuilder, Magritte, Pier, ... are examples of models that are independent of their view. Sport provides platform independence for files, sockets and exceptions. When we evaluated Sport for Seaside it only worked on VW and sockets were at the wrong abstraction level. Also to consider is that exceptions are pretty portable today. Grease is merely a collection of utilities to deal with strings, collections, encoding, message sends, versions and packages. It also includes a large collection of ANSI tests documenting what Seaside expects from the platform. For networking it depends on what you want to do. If you want sockets, then Sport is probably the way to go. If you want to serve HTTP then Seaside-Core is what I would pick: This does not include WAComponent and WASession, it provides platform independent request/response objects. Through adaptors it runs identically on all platforms that support Seaside and with many different web servers (for Pharo this is Zinc, Kom, KomLight, Swazoo, FastCGI, and probably others). As you see, all these examples work because they separate code that works on one platform and with one output format from the rest of the code. You can do this in any domain, but it is the easiest if you build on something that already works. An exception is PetitParser: It works on many platform without changes because it expects only a tiny subset of ANSI, the rests it simply implements itself or packages separately.
