Hi Annick. I don't know which image they told you, but if you take a PharoCore 1.1.1 from here: http://www.pharo-project.org/pharo-download/stable-core And you evaluate: ScriptLoader new cleanUpForRelease. And then save and quite, the image is 6.8 MB. Another hack I sometimes do is o put all all classes with the default category. You can still can browse and recompile the whole image. Most production enviroments don't care about categories...they make sense when developing. (not everybody agree). But anyway, if you then evaluate: Smalltalk allClassesAndTraitsDo: [:each | each zapOrganization ]. Symbol compactSymbolTable. Smalltalk garbageCollect Then the resulted image is 6.1 mb ;) If you then evaluate: "Compact all MethodDictionary instances" | oldInstances newInstances | oldInstances := MethodDictionary allInstances. newInstances := oldInstances collect: [ :md | (MethodDictionary new: md size) compactCopyFrom: md; yourself]. oldInstances elementsForwardIdentityTo: newInstances. "Different cleanUps" TextStyle allSubInstancesDo: [:ts | ts newFontArray: (ts fontArray copyFrom: 1 to: (2 min: ts fontArray size))]. "Clean all Monticello related stuff. You won't be able to browse packages for example" MCWorkingCopyBrowser allInstancesDo: [:each | each flushAllCaches ]. MCWorkingCopy allInstancesDo:[:wc| SystemChangeNotifier uniqueInstance noMoreNotificationsFor: wc. wc unregister]. SystemChangeNotifier uniqueInstance noMoreNotificationsFor: MCPackageManager. SystemChangeNotifier uniqueInstance noMoreNotificationsFor: MCWorkingCopy. "Most application don't need sound" SoundService default: nil. SoundService unregister: DummySoundSystem. SystemChangeNotifier uniqueInstance noMoreNotificationsFor: (Smalltalk at: #RecentMessageSet). TranscriptStream newTranscript: ThreadSafeTranscript new. ImageSegment classPool at: #RecentlyRenamedClasses put: Dictionary new. ExternalSettings classPool at: #RegisteredClients put: Set new. Locale classPool at: #LocaleChangeListeners put: nil. "Clean all the changes" ChangeSet resetCurrentToNewUnnamedChange Set. ChangeSet current initialize. ChangeSet classPool at: #AllChangeSets put: (OrderedCollection with: ChangeSet current). Symbol rehash. 3 timesRepeat: [ Smalltalk garbageCollect. Symbol compactSymbolTable ]. You will have a 5.9 MB image :) is that enought? If not, you can start unloading packages. Esteban did a lot of work with this of IPhone images. You can ask him. ps: I wonder if any of those scripts should be added to ScriptLoader Cheers Mariano On Tue, Jan 4, 2011 at 6:48 PM, Annick Fron <info(a)afceurope.com> wrote: > Hi all, > > I have now tried the minimal images indicated by Torsten and Stephane, on > Windows it amounts to 9.1 Mega in memory ... > Would it be smaller on Linux ? > Yet, I still need a shoe horn, having only 8 M ram from which 1.5 is > already taken by the kernel... > Any idea to downsize even more ? > Best regards > > Annick Fron >

[Pharo-project] ConfigurationOfPharo: now with Mocketry, Autotest, XMLSupport and Helps
by laurent laffont Jan. 5, 2011

Jan. 5, 2011

Hi, I've updated ConfigurationOfPharo 1.2-beta2: Added: - Mocketry - XMLSupport - Autotest - Shortcuts-Help more tests and Help. I've put methods in categories. Can someone check ? For independent Help packages, shouldn't we create a ConfigurationOfPharoHelp ? Cheers, Laurent Laffont Pharo Smalltalk Screencasts: http://www.pharocasts.com/ Blog: http://magaloma.blogspot.com/

Yes, we will look into setting up a Mac and a Windows slave soon. One idea is to use an older intel mac and install windows there as a virtual machine and use this machine for both windows and mac. Alternatively, Hudson can have Amazon E2C slaves... for windows, that would be an alternative (but an expensive one). Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.

[Pharo-project] Hudson Win setup build

Would be nice if Hudson could also build the Pharo windows setup automatically in the future. Should be easy to setup. I know thats not the highest prio but I wanted to check if it is possible anyway (dont know what kind of machine the ci server is currently runnning on). Since I think VM's are built in the future via Hudson too there must be access to a win32 machine anyway. Thx T. -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!

[Pharo-project] Generators for Pharo Xmax wish)
by Ralph Boland Jan. 5, 2011

Jan. 5, 2011

I earlier posted a Xmas wish that Pharo add generators (steal the generators code from Squeak). No one appeared to be familiar with them. The generators code was added to Squeak by Andreas Raas. The class Generator can be found in Squeak as a subclass of Stream. It's about 140 lines of code and, as I said before, is really useful and needed in order for me to port some of the packages I am developing from Squeak to Pharo. Class Generator is tested in class GeneratorTest which also serves as examples of uses of Generators. So please, someone go steal the code! And stealing is easy. For example I stole the following comment on class Generator directly from the class comment: " A Generator transforms callback interfaces into stream interfaces. When a producer algorithm provide results as callbacks (blocks) and a consumer algorithm expects streamable input, a Generator transforms one into the other, for example: | generator | generator := Generator on: [:g| Integer primesUpTo: 100 do:[:prime| g yield: prime]]. [generator atEnd] whileFalse:[Transcript show: generator next]. " Regards, Ralph Boland

> Finally I implemented the posibility of create a custom windows in > CLFramework. That really rocks! Looks cool. And I'm glad that you continue working on it since the result is really impressive. One of my goals this year is to find the time to have a look at UI framework and to start building one or the other small helper tool with it to give feedback. Is it working with 1.2 already? What is planned next! Thanks Torsten -- Neu: GMX De-Mail - Einfach wie E-Mail, sicher wie ein Brief! Jetzt De-Mail-Adresse reservieren: http://portal.gmx.net/de/go/demail

Those that have Help pages, then it would be really cool to have a separate package for them. - For each external package, they need to only to put Help pages in a separate package, but also create a group for them in the Metacello Configuration. Then, people can choose what to load. - PharoDev should include the metacello groups that contains the Help. Now...regarding this example, about the shortcuts...that is related to PharoCore...So, we have to options: 1) Cotinue commiting them in 'http://www.squeaksource.com/HelpSystem' and create a ConfigurationOfPharoHelp that we load for the dev image 2) Commit them into PharoCore and then remove them in #cleanUpForProduction I am not sure which I like more, but I think 2). Since we have Help already integrated in the core, the idea is to use it, isn't it ? otherwise this should be in the dev image. And I like to have the Help as closer as possible to the real code. So, I choose for 2), but of course, I am all ears. Cheers Mariano > Cheers, > > Laurent Laffont > > Pharo Smalltalk Screencasts: http://www.pharocasts.com/ > Blog: http://magaloma.blogspot.com/ >

Ok, that's not needed for a deployed app since it will decompile the methods in case you browse them (you wont have the tmp names thought), To get rid of sources, you need to evaluate Smalltalk abandonSources > > The minikernel image is 2 mb > > Now you should also release the cache of MC and do several incantation > and you can get to a more reasonable size. > > I am not too familiar with the environment, so it will me some time before > I understand package loading and so on. > I don't understand why there are shell scripts together with Smalltalk > scripts. > The shell scripts are just to shrink down the PharoCore image and build a PharoKernel from it. You can just download the PharoKernel image (no need to run the shell scripts, this is only if you want to build the PharoKernel by your own). But be aware that PharoKernel is REALLY kernel.

[Pharo-project] editing a method outside the image?
by sergio_101 Jan. 4, 2011

Jan. 4, 2011

one problem i having (in a long line).. is that my DateAndTime class >> now looks like this: now ^ self basicNew ticks: (Duration days: SqueakEpoch hours: 0 minutes: 0 seconds: self totalSeconds nanoSeconds: MillisecondClockOffset milliSeconds * NanosInMillisecond) ticks offset: self localOffset; yourself the problem is, milliseconds is not defined anywhere.. this is there as a remnant of sheduler.. i need to replace it with the REAL one: now ^ self basicNew ticks: (Array with: SqueakEpoch with: Time totalSeconds with: 0) offset: self localTimeZone offset the problem is that when i try to update "now", i keep getting the error for that it can't find "milliSeconds".. when i delete "now" and try to paste the correct one in.. i error out, too.. i think the snake is eating its tail.. can i replace the "now" method somehow with the image not running? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101
