Very nice. I like the casts being faster :). In a few places (e.g., where you have to read text from the help system to be able to follow) it was slightly too fast, though.

[ANN] Pharocasts: SandstoneDb (with subtitles !)

by laurent laffont

Hi, I've just uploaded a new screencast which introduces SandstoneDb (and also HelpSystem). http://pharocasts.blogspot.com/2010/04/sandstonedb-simple-activerecord-styl… Note this is my first one with subtitles. There's a link so you can download it and translate it (some people have asked for that). I've used SubtitleEditor (http://home.gna.org/subtitleeditor/) but I don't really like it. Do you know a better software on Linux ? The video is accelerated, it's more dynamic IMHO ( to do this in avidemux, just go in video menu, framerate, and put a higher framerate). <http://pharocasts.blogspot.com/2010/04/sandstonedb-simple-activerecord-styl…> Cheers, Laurent Laffont

Implementing a "prototype" in Pharo

by Miso

Hi, I'm trying to creating a concept similar to "prototype" (like prototype-oriented programming) in Pharo. What I want is an object's methodDictionary to be stored in itself. So when I send a message to an instance, Pharo should look in the instance's dictionary (as opposed to class' dictionary) and call method stored there. Closest thing I managed to do was create an anonymous class (subclass on my custom class) for each instance and return instance of this class, and store the anonymous class in the instance so I can work with it. Is there any other way to do it, without modifying compiler/VM or writing custom compiler? If not, please give some pointers where to look for some information about "core" of Pharo.

Re: [Pharo-users] How To Bind To External Libraries in Pharo ?

by Mariano Martinez Peck

Hi Bill. You have 2 possibilities: 1) Use FFI. With this you can call C functions from shared libraries. No need to recompile de VM. Main problem: it locks the whole VM while the function is being run. The FFI is included in most VMs so it is easy. What you DO need to install is the smalltalk side of FFI. A simple way in Pharo is evaluating: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfFFI'; load. ((Smalltalk at: #ConfigurationOfFFI) project version: '1.2') load. There are a lot of examples and libraries wrapped with FFI. We developed a wrapper for the OpenDBX library....the project is call SqueakDBX ( www.squeakdbx.org) and would be useful if you want a real example using FFI. FFI: http://wiki.squeak.org/squeak/1414 2) Write your own named plugin. This is, you write your plugin in SLANG (a limited Smalltallk that it is used to write part of the vm and then translated to C) and then, using VMMaker you generate C code, and after, you can generate the binaries. Finally when you distribute your app you will need to add such plugin to the VM. http://wiki.squeak.org/squeak/356 http://wiki.squeak.org/squeak/464 Particulary for GTK, look at the project (I think it is dead now) SqueakGTK: http://squeakgtk.pbworks.com/ Particuolary for Gstreamer I paste an email from John Macinstosh some time ago:* "Well I'm not sure what you are asking for. The Gstreamer stuff starts at: MCHttpRepository location: 'http://www.squeaksource.com/GStreamer' user: '' password: '' You need a plugin and the GStreamer underpinnings install in your operating system. If you have have a linux box that is easy. If you have a mac, you could use MacPorts to install GStreamer and I could give you a plugin I built for test purposes. As for the Sophie stuff, well it uses FFI for talking to Quicktime, there is an optional quicktime plugin but all that is used for is to let quicktime tell us when it has rendered a frame into a squeak surface so we can signal a squeak semaphore to draw the surface to the Display. The fall back is to do a fixed frame rate drawing cycle, which is what happens on Windows. The Sophie player of course uses Tweak as a reference base, but could be converted to some other UI framework."* Cheers Mariano On Wed, Apr 21, 2010 at 7:10 PM, Bill Rodgers <mrbillrodgers(a)gmail.com>wrote: > Very cool ! > > Thanks, > > Bill > > > On Wed, Apr 21, 2010 at 1:58 PM, StÃ©phane Ducasse < > stephane.ducasse(a)inria.fr> wrote: > >> Hi bill >> >> you can use FFI, we should write a chapter.
