Re: [Pharo-project] PetitSmalltalk: now with a self-contained grammar for number literals

Hi Lukas, I haven't :) mainly because I'm unsure where to put it - is there perhaps a PP Inbox, or shall I just post the merged version, or what's your preference?

[Pharo-project] PetitSmalltalk: now with a self-contained grammar for number literals

by Frank Shearar

Hi, I branched off PetitSmalltalk-lr.50 and (finally) completed a number grammar. I also completed (*) the GNU Smalltalk grammar + parsing, which is currently in a separate package. So, my question: I have a version merging my changes with PetitSmalltalk-lr.56: shall I submit that (together with the other versions in my branch), or in what other form may I present my work for submission? Thanks, frank (*) I may have missed any special literals - I think GNU Smalltalk has an @@(1 2 3) array literal, for instance.

[Pharo-project] [Vm-dev] CogDroid: first public alpha available for testing

by Dimitry Golubovsky

Hi, Thanks for the interest to the CogDroid alpha. Answering to all questions here. @Gary: I'm afraid I am almost the one involved with this at the moment ;) I do not have a specific timetable, and my next step is to create a meaningful tool to make JNI calls to the Java libraries available on Android, since Google discourages many things to be done natively. I think I'll announce beta after that's ready. Regarding etoys, I think it is possible to try the original image, or whatever is available from the Scat project [1] (OK, that's Scratch, but IMHO similar purpose) with the new VM. Monticello should work (or if it does not work in any way, please let me know). In other words, the more people help me with testing, the sooner we get a higher grade release. Regarding older images, one thing to keep in mind is how much polling they have [2]. Although I (remembering from prior discussions) also made browserPluginExitIfNeeded (sp?) to exit the interpreter if it is running too long (current time quant is 200ms although this si very soft rule), so event serverMode may be not so necessary. The VM writes a log file located at /sdcard/jni.log. Upon exit (via the Quit/Save and quit item of the world menu) it writes VM time statistics in that file: what was average time in interpreter, average time between interpreter calls, etc. This may also give some idea. @Igor: There are three things to merge simultanesously. My dmg-blessed repo at Gitorious [3], and the two packages at squeaksource.com/EventVM: CMakeVMMaker-golubovsky.138.mcz and VMMaker-oscog-golubovsky.121.mcz Not sure how you adjust ConfigurationOfCog for these, but I think they should go to the bleeding edge configuration. Besides, can Google SDK and NDK be installed on Hudson to test at least buildability? Or I might install a build slave at my computer solely to test Android builds, but we need to discuss this in separate thread. @Stephane: I don't think of any actions on the image side at the moment since it works with 1.3, and after involving the timed executionI was able to even draw a PolygonMorph (although very slowly, but at least the application did not crash every time, only sometimes ;) @Mariano: Thanks. And we have the first benchmark (will also add it to the wiki): Notion Ink Adam, Android 2.2 1 GHz, Dual-core ARM Cortex -A9, Nvidia Tegra 250 Classic VM - Squeak 3.9 36,930,178 bytecodes/s 1,201,501 sends/s Stack Cog - Squeak 3.9 41,775,456 bytecodes/s 2,074,373 sends/s which seems a very good speed improvement. ------------------------------- [1] http://code.google.com/p/scat/ [2] http://lists.squeakfoundation.org/pipermail/vm-dev/2011-August/009209.html [3] http://gitorious.org/~golubovsky/cogvm/dmg-blessed -- Dimitry Golubovsky Anywhere on the Web

[Pharo-project] Installing TextLint on top of PharoKernel

by Damien Cassou

Hi, I tried to download PharoKernel and execute the following script but nothing happens: Gofer new renggli: 'petit'; package: 'PetitParser'; load. Gofer new squeaksource: 'textlint'; package: 'TextLint-Model'; package: 'TextLint-Console'; load. WorldState addDeferredUIMessage: [ SmalltalkImage current snapshot: true andQuit: true ]. I got PharoKernel from https://ci.lille.inria.fr/pharo/view/Pharo-Kernel/job/Pharo%20Kernel%20Gofe… Thank you -- Damien Cassou http://damiencassou.seasidehosting.st "Lambdas are relegated to relative obscurity until Java makes them popular by not having them."
