[Pharo-project] MC load vs merge

by Camillo Bruni

Hi everyone, I am improving the way the Monticello UI handles conflicts when doing a load. Right now you just get a warning which lets you decide whether to overwrite the local changes or simply cancel the action â a merge action is missing! I added the marge behavior, so far so good, but there is a slight glitch: The conflict message is shown based on conflicts on the package level, for performance reasons. Lets assume that the loaded version only contains new classes for the package that you changed locally, you still get a conflict message although the changes can be loaded without problems. So my question is on how to load stuff in this case: - go the git/svn way and load everything if there are no conflicts - load everything if there are only added entities (not removals/modifications) - always show the merge/diff view to check what changed manually cami

The code snippet doesn't tell that much. Registering a Block for execution on request is probably not what makes you excited about. What is exciting about it is that javascript is written in a strictly asynchronous manner (event driven) and that matches perfectly the implementation with asynchronous I/O. Suddenly you can write programs they way you ever wanted it. And lucky for us smalltalk itself is event driven so it can go there easily, too. ... > > > In theory yes, in pratice no.

Re: [Pharo-project] Developing on virtualized Android

I was able to run the following application: http://squeakvm-tablet.googlecode.com/files/CogDroid86-alpha-20110928.apk under this version of Android-x86: http://android-x86.googlecode.com/files/android-x86-2.3-RC1-eeepc.iso (or check their downloads page: http://code.google.com/p/android-x86/downloads/list - each netbook-specific ISO has its own set of drivers, and something may not be provided by KVM or any other virtualizer). Do not use the 2.2-generic ISO - it has many problems. Brief howto for KVM: 1. Create a virtual image for "hard disk" to use with KVM. Boot from the ISO image. For network adapter, specify "pcnet": -net nic,model=pcnet eeepc ISO does not have a driver for say rtl8139 2. After you see that the ISO boots, install on "hard disk". You will be given an option to create a fake sdcard: say Yes. SD card image will be allocated within the KVM's "hard disk". Select ext2 or ext3 as hard disk filesystem. 3. Install grub when asked. Later, if you need to edit grub boot menu, do this: In KVM, press Alt-LeftArrow to get to the root console. Mount the boot disk (unlike typical Linux, there is no boot volume mounted implicitly) mkdir /data/fs mount -t ext3 /dev/block/sda1 /data/fs vi /data/fs/grub/menu.lst umount /data/fs reboot 4. Install AndroZip application, otherwise you will not be able to download zip files 5. Install some file manager (2.3 seems to already have OpenIntents file manager installed) 6. Download the zipped Squeak image+changes+sources: http://squeakvm-tablet.googlecode.com/files/sqandr_pres.zip or whatever other image you would like Unzip the zipfile (tap on it; it will be unzipped under /mnt/sdcard/AndroZip) 7. Install CogDroid alpha mentioned above. When started, it will display usual list of images to boot. I got the following benchmark: 85,906,040 bytecodes/sec, 5,183,202 sends/sec. Emulator's /proc/cpuinfo says QEMU Virtual CPU version 0.9.1, 1986 MHz, 3973 bogomips. It runs under physical CPU: processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 75 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ stepping : 2 cpu MHz : 1999.903 cache size : 512 KB bogomips : 3999.80 8. Note on mouse buttons: Left click acts as screen tap (long click is long tap, e. g. on home screen use it to move/delete shortcut icons). CogDroid does not distinguish between long and short taps. Right click acts as the "Back" hardware button. So, to "Print-it": right click, see "Mouse yellow" popup, left click brings up menu, select Print. Middle click (press on the scroll wheel) acts as "Menu" button (to bring on the onscreen keyboard, but you can use the physical one ;) No way to do the Blue click (I use the "Forward" button on Pandigital, but it seems not to be typically available). So if you want to try Pharo, remap mouse buttons if possible. Hope this information is useful. Adjust to your virtualizer ;) Thanks.

[Pharo-project] No 'accept' menu on Samsung Galaxy tab/Pharo (was Re: New CogDroid alpha: with intent filter.)

by stan shepherd

On the Samsung Galaxy, CogDroid with Pharo (1.4) gives me the 'mouse yellow' graphic, but following click does not give the 'accept' etc menu. It will select a menu morph. None of the buttons emulate 'mouse blue' on the Galaxy. With Cuis 'accept' is OK, and on Squeak if swapMouseButtons is disabled. With touchscreen, no shift/ctl modifiers are available. Has anyone managed a setting or snippet to make this work on Pharo? ...Stan On 18 September 2011 07:29, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > thanks dimitry > this is cool > I would like to buy a tablet for our team to try pharo on it. > What do you suggest? > > Stef > > > On Sep 18, 2011, at 6:54 AM, Dimitry Golubovsky wrote: > >> I have uploaded a new alpha of CogDroid: >> >> http://squeakvm-tablet.googlecode.com/files/CogDroid-alpha-20110918.apk >> >> Intent filtering has been added to the application.

[Pharo-project] Loading OmniBrowser in 1.3 Core

by HernÃ¡n Morales Durand

I've already loaded AST and RB in a Core 1.3 #13299, how do you load OmniBrowser with Shout support? I've evaluated without success: Gofer new squeaksource: 'PharoOB'; package: 'ConfigurationOfOmniBrowser'; load. ((Smalltalk at: #ConfigurationOfOmniBrowser) project version: #stable) load. "The symbolic version #stable is not defined in ConfigurationOfOmniBrowser for the current platform." (Smalltalk at: #ConfigurationOfOmniBrowser) project latestVersion load "MessageNotUnderstood: Preferences class>>enable:" Cheers, HernÃ¡n

No, but you can fix this by loading bleedingEdge from omnibrowser. Norbert
