[Pharo-project] Pharo won't make a VM in linux
by Javier PimÃ¡s Feb. 24, 2010

Feb. 24, 2010

This is a spin-off of the Alien's building thread, I think it deserved it's own thread. I first faced this while trying to build alien, but then I noticed it's unrelated. The VM is not building in linux, and I think it's not caused by my machine's configuration. I'm using 1.0RC2, with VMMaker loaded yesterday using configurationOfVMMaker. I also applied ObjectMemory initializeWithBytesToWord: Smalltalk wordSize. as told in the other thread to fix some issues. Plugins are: - internal: B3DAcceleratorPlugin, BaloonEnginePlugin, BitBltSimulation, FilePlugin, SocketPlugin. - By the way, I'm also having to include some dummy plugin as external. If I don't, cmake will make some weird stuff like creating a = directory and then fail. I use ADPCMCodecPlugin. The errors are these: ... Linking C executable squeakvm B3DAcceleratorPlugin/libB3DAcceleratorPlugin.a(sqOpenGLRenderer.c.o): In function `glRenderVertexBuffer': /home/javier/st/squeak-svn/platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.c:846: undefined reference to `glColorMaterial' /home/javier/st/squeak-svn/platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.c:847: undefined reference to `glGetError' /home/javier/st/squeak-svn/platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.c:848: undefined reference to `glEnable' /home/javier/st/squeak-svn/platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.c:849: undefined reference to `glGetError' ... /home/javier/st/squeak-svn/platforms/unix/plugins/B3DAcceleratorPlugin/sqUnixOpenGL.c:159: undefined reference to `glLightModelfv' /home/javier/st/squeak-svn/platforms/unix/plugins/B3DAcceleratorPlugin/sqUnixOpenGL.c:160: undefined reference to `glGetError' collect2: ld returned 1 exit status make[2]: *** [squeakvm] Error 1 make[1]: *** [CMakeFiles/squeakvm.dir/all] Error 2 make: *** [all] Error 2 Maybe it should be linking to opengl lib but it isn't, what do you think?

[Pharo-project] About changes and so on: Authorize - at any position in binary selectors (like VW 7.7)
by StÃ©phane Ducasse Feb. 24, 2010

Feb. 24, 2010

After the lengthly discussion about the fact that Smalltalk implementation is a balkan region (cf "what Pharo/squeak do not parse 16rFF) > Authorize - at any position in binary selectors (like VW 7.7) > See http://bugs.squeak.org/view.php?id=3616 > Address the problem of compiling 1@-2 with following strategy: > > If compiler is non interactive, then compile with backward compatibility 1 @ (-2). > If compiler is interactive, propose a menu to disambiguate and insert a proper space. > 1@ -2 -> MessageSend receiver: 1 selector: #'@' argument: -2 > 1@- 2 -> MessageSend receiver: 1 selector: #'@-' argument: 2 > > Warning: Squeak did understand (1@- 2) as (1 @ (-2)).... > I didn't do anything to support this vicious Squeakism, and by now the semantics are change. I was wondering what do we do with that kind of changes. Is it useful? what is the end user case? what are the binary operators that we could invent with -~- -| -@ nicolas do you have a case in mind? what VW people use it for? Now do we want this in pharo? What is the cost? Impact / broken code? > Stef

[Pharo-project] HelpSystem & Class comments
by Torsten Bergmann Feb. 24, 2010

Feb. 24, 2010

Crosspost squeak-dev/pharo-dev Andreas Raab wrote: >a) Currently a book depends on the presence of HelpSystem (i.e., via >subclassing). No, you are not forced to be in the "CustomHelp" hierarchy. You can define an own hierarchy, directly as subclass of Object, whatever (athough I would recommond CustomHelp as common superclass similar to TestCase in SUnit) The standard builder ("HelpBuilder") is able to use a different root. See HelpBuilder class>>buildFromRoot: and HelpBuilder>>defaultRoot. With HelpSystem-Core-tbn.16 I even allow to provide own builders. To get the latest you can just load the baseline: (ConfigurationOfHelpSystem project version: '1.0-baseline') load b) Typing in '' quotes is pretty insane when you quote text. I know, but this is annoying since you currently write it manually using the browser and by adding methods yourself. Storing the contents in method is just the vehicle - additional authoring capabilities would help here in the future (an additional HelpEditor beside the HelpViewer). Again you judged too early. I would also like to see some reactivation of Scamper code for a more capable viewer/editor - since with a basic support for simple markup we could catch two flies by providing in-image and web-help with the same contents/source. >I'm not saying that comments are the only way by which HelpBooks should >be created but I think that this should be one of the ways that >HelpSystem directly supports. That's already there - Danny already added this for the help classes. Just open the book "Help on Help" -> "HelpSystem API Documentation" and subnodes after loading the latest baseline. If you click on a class node you will see the class comment displayed in the help (currently as ASCII). We may add a book "Reference" where you open two subbooks: "By categories" and "By hierarchy" - displaying the classes using categories or in their usual class hierarchy for browsing. However: the main question to me is the kind of format we should use: a) Wiki Style or similar + easy to write + easy to transform - mostly non-standard With Maven the APT format is often used [1], Eclipse for instance provides even editors, see [2] for screenshots) But we also have Tiny wiki syntax somewhere on SqueakSource which may be similar. b) real markup like HTML + easy to put onto the web without tranformation - we need to have more markup support -/+ embedding of Smalltalk has to be done the W3C way, similar to javascript <a href="smalltalk:..." c) specific format like Squeaks Text representation with textDoits, ... - very Squeak specific and may not work in Pharo - hard to put on the web I would like to see b) with a cleaned up Scamper code since a general markup editor/viewer would be helpfull anyway and it would be easy to publish stuff on the web. But looks like more work. There is also another HTML browser with markup and CSS now available open source as MIT (WithStyle), see [3] and [4] for more info. Maybe someone has a minute ;) Bye T.

Hi Ramiro, something happened between Pharo1.0-10502-rc1dev09.12.2. and 10508 related to Networking.

>Janko, I don't know what it "decent" for you, but did you try Metacello-OB >and Metaceller ? I think what is still missing is a common tutorial showing all the details and pieces that are already here today. Not everybody reads the blog posts from Dale or follows the mailinglists. Is there a preview/early draft for the book chapter on Metacello available? Could it be posted/discussed here? Thx T. -- NEU: Mit GMX DSL Ã¼ber 1000,- Â¿ sparen! http://portal.gmx.net/de/go/dsl02

Hi guys I would like to know which version of shout we are using and relying on. Apparently one version was integrated on squeak and I would like to make sure that the one we use continue to get improved. One of these days we will have to think about the status of important packages that are external to pharo: shout, XMLSupport.... Stef
