[Pharo-project] File Out html with Syntax Highlighting
by Nathan Tuttle Feb. 11, 2010

Feb. 11, 2010

I find it very useful when learning a language to see the code accurately syntax highlighted on a web page when a snippet is shown. I want to design a fileout method that will allow developers to file out code with html to put into a web page. I know I need to use RBFormatter; any ideas on where to go from here? Where do I get a codestream for example? thanks

[Pharo-project] Live Distributed Objets - Why not in Smalltalk ?
by CÃ©drick BÃ©ler Feb. 11, 2010

Feb. 11, 2010

Hi people (crosspost pharo and research) While googling for live objects, ie. an API to query live objects coming from the outside world (trade stuffs, information, or whatever information coming from a sensor etc...), I think I just found what I was lokking for. At least something exists. I think this is different from Croquet or Spoon (I think live objets don't need to be in another image, they are just independant entities). On this page [1], you'll find video demonstrating live objects (2nd part of the first one is really cool, especially when they drop the coordinate of a plane in the window...or when they inspect live objets). 2nd video id about integration in office tools. On this same page, there are several publications at then end. [2] and [3] are wikipedia references. Were you aware of that ? Could we build a platform in Smalltalk (I don't really need it, but I find this would be really cool). I don't need such a platform, this was just a midnight googling session... but hey it's coool :) Quote from wikipedia (as you can see Smalltalk inspired them ;) : "Originally, the term was used to refer to the types of dynamic, interactive Web content that is not hosted on servers in data centers, but rather stored on the end-user's client computers, and internally powered by instances of reliable multicast protocols. The word live expressed the fact that the displayed information is dynamic, interactive, and represents current, fresh, live content that reflects recent updates made by the users (as opposed to static, read-only, and archival content that has been pre-assembled). The word distributed expressed the fact that the information is not hosted, stored at a server in a data center, but rather, it is replicated among the end-user computers, and updated in a peer-to-peer fashion through a stream of multicast messages that may be produced directly by the end-users consuming the content; a more comprehensive discussion of the live object concept in the context of Web development can be found in Krzysztof Ostrowski's Ph.D. dissertation[3]. The more general definition presented above has been first proposed in 2008, in a paper published at the ECOOP conference[8]. The extension of the term has been motivated by the need to model live objects as compositions of other objects; in this sense, the concept has been inspired by ***Smalltalk***, which pioneered the uniform perspective that everything is an object, and Jini, which pioneered the idea that services are objects. When applied to live distributed objects, the perspective dictates that their constituent parts, which includes instances of distributed multi-party protocols used internally to replicate state, should also be modeled as live distributed objects. The need for uniformity implies that the definition of a live distributed object must unify concepts such as live Web content, message streams, and instances of distributed multi-party protocols." -- CÃ©drick [1] http://liveobjects.cs.cornell.edu/ [2] http://en.wikipedia.org/wiki/Live_distributed_object [3] http://en.wikipedia.org/wiki/Distributed_data_flow

[Pharo-project] OpenGL in pharo?

>It would be good to have 'AlienFFI working on linux' published so that we >can use it. I still wonder what's required to have it available on any Squeak/Pharo platform (incl. Windows) similar to FFI? Does one just have to generate the plugin or is OS specific code required? Bye T. -- GRATIS fÃ¼r alle GMX-Mitglieder: Die maxdome Movie-FLAT!

[Pharo-project] fixTemps and BlockContext question
by Luc Fabresse Feb. 11, 2010

Feb. 11, 2010

Hi all, I wonder why BlockContext>>fixTemps is still in PharoCore. I guess that it should be removed, isn't it? It has only one sender. Morever, should the BlockContext class be removed too? Depending on answers, I will write a bug report. Luc

[Pharo-project] Pharo screencasts - how to
by laurent laffont Feb. 11, 2010

Feb. 11, 2010

Hi, I want to share how I record screencasts for Pharocasts http://pharocasts.blogspot.com/ in case someone wants to participate. Now there's 11 screencasts. The difficult part is to have a good idea / scenario for a screencast. Comments and ideas are welcome. If you want to publish on Pharocasts I can give you write access. Or if you have a "draft" screencast I can edit it / re-record it for publishing. I try to record screencasts with a minimum duration of 5 mn. These instructions are for Linux (but I'm a beginner in video stuff). I don't know which software to use on other operating systems. Have advices ? I record with xvidcap http://xvidcap.sourceforge.net/. I define a capture zone of 800x600 (use 4:3 or 16:9 standard resolution. If not you can have poor encoding results). Set multi-frame mode (you have to right-click on the file button to access preferences, not very intuitive). I choose AVI format / MPEG 4 codec. If you open / close applications for the screencast, note that KDE has very good options to memorize / force windows positions, so they are always opened in your capture zone.(Other window managers like E17 have these sort of options). The trick is to not stop recording when you write errors, you can cut the "wrong" parts later. To edit the video, I use avidemux http://fixounet.free.fr/avidemux/. It has Qt and Gtk GUI and work on Linux / Windows / OSX / BSD ..... It's really easy to use. When you want to cut a part, you define the beginning with the A button ( Ctrl-[ ), the end with B button ( Ctrl-] ), then Edit -> Cut ( Ctrl-X ). You can navigate using arrow keys. When finished, click on save (Choose another filename !!). So now you have your screencast in .mpeg file. Note that people using MacOSX Tiger or older have problems to watch this video. So I convert in .mov using ffmpeg http://www.ffmpeg.org/ like this: ffmpeg -i my_video.mpeg -b 500k my_video.mov. (but I think it's not the best command as the video size is bigger and quality lower). To publish the video I use Vimeo http://vimeo.com/. I've tried YouTube and Daily Motion but the quality is lower or the video duration is limited. I had problems using the "standard uploader", so I switch to the "basic uploader" on the download page, works better. It's really fun to record screencasts, and a good way to show development practices. Cheers, Laurent Laffont

Hi, Do you know if it's possible to export smalltalk code in ruby ? I have to port a small app I did and so, it could help me :) I don't think there's an existing tool, but maybe some directions... Actually, I'd prefer writing a simple tool to do that rather than doing all by hand. I don't expect it to work out of the box, but just save me some time. TIA -- CÃ©drick

[Pharo-project] RBAbstractClass>>isAbstract
by Fernando olivero Feb. 10, 2010

Feb. 10, 2010

Lukas, do you think the second statement in this method could be removed, it would take a lot less time to know if a class is abstract. RBAbstractClass>>isAbstract (self whichSelectorsReferToSymbol: #subclassResponsibility) isEmpty ifFalse: [^true]. model allReferencesToClass: self do: [:each | ^false]. ^true I know it would change the definition of what is an abstract class for RB, but i'm just wondering if this is ok: "A Class is abstract if it defines a subclassResponsibility method and no other classes reference it" The second clause in my opinion could be avoided. Maybe it would be better to separate this method into: RBAbstractClass>>isAbstract ^ (self whichSelectorsReferToSymbol: #subclassResponsibility) notEmpty RBAbstractClass>>isUnreferenced model allReferencesToClass: self do: [:each | ^false]. ^true Thanks, Fernando
