Re: [Pharo-users] squeak vm without MMU

by Javier PimÃ¡s

Well, I think it should be. In SqueakNOS we load squeak/pharo without libc and can work without memory management at all. The thing that should be tricky is were do you place things in memory, so you don't break other programs. Actually, for libc we implement just a minimal set of needed functions like printf, memcpy, etc (if you are interested you can look at our sqLibc.c file and the makefile which picks functions from glibc). For the functions you mention, I believe pharo can live without them, but of course you'll probably have to create your own platform with makefiles and tweaks. Also, libraries can be compiled as internal and that should solve most of the problems. Hope that helps! Javier.

Re: [Pharo-users] [Pharo-project] Updated ConfigurationsOf...scripts?

by Dale Henrichs

HernÃ¡n, It _is_ possible to write some scripts that could automate the checking: ConfigurationOfXXX project updateProject loads the latest version of the mcz file for the configuration. Then you could write a little script like: | project | project := ConfigurationOfXXX project. project updateProject project currentVersion < project latestVersion ifTrue: [ self inform: 'A new version of ConfigurationOXXX is available' ]. to simplify the check for new versions a bit more...you could even automate the load of the newer version if you were brave:) Dale On 01/12/2011 01:56 PM, HernÃ¡n Morales Durand wrote: > Yes thanks. > notice there are 80+ ConfigurationOf... in the MetacelloRepository and > so many not listed there > > 2011/1/12 laurent laffont<laurent.laffont(a)gmail.com>: >> Isn't what you're looking for ? >> http://book.pharo-project.org/book/PharoTools/ >> Laurent >> >> On Wed, Jan 12, 2011 at 8:44 PM, HernÃ¡n Morales Durand >> <hernan.morales(a)gmail.com> wrote: >>> >>> Ok if there are not, I think is a must, I spend a lot of time >>> searching for the updated scripts or exporting/importing them in my >>> images.

The stack-trace and your code snippet does not match. There are no references (and should be no references) to #compileTree: or RBClass in the code you pasted into the mail. The easiest is probably if you use the refactoring tools as integrated into OB. This does all automatically.

squeak vm without MMU

by Annick Fron

Hi, Is it possible to use pharo on a processor with MMU (Memory Unit Management ) ? Namely my target OS is a Linux with the following differences : ============ The kernel is a collection of patches to make the standard Linux kernel run on CPUs that do not have an MMU. As a consequence you will encounter some differences between the kernel and the standard Linux behavior: u no fork() â consider using vfork() instead but beware of the difference of their semantics u no daemon() â it is usually implemented on top of fork and cannot be easily replaced without changing the semantics. u fixed stack size -- the stack of an application is set at execution time and cannot grow during runtime. The default stack size is 4k! It can be increased with the "-s" option of m68k-uClinux-elf2flat. u limited libc compared to glibc -- either add more to libc, or remove some functionality. u no support for ELF binary file format u very limited support for shared libraries due to missing MMU -- all applications get linked statically u mmap() is very inefficient u no paging -- applications have to be loaded completely into RAM, the heap is very susceptible to fragmentation. ======== Annick Fron

Finding RB parse tree rule for replacements

by HernÃ¡n Morales Durand

Recently I wanted to replace all method sends of oldMessage to newMessage in a specific method category in a class, then I wrote this little script I want to share with you: | className realClass replacer category | className := #MyClass. realClass := Smalltalk at: className. category := #accessing. replacer := RBParseTreeRewriter new replace: '`receiver oldMessage' with: '`receiver newMessage'; yourself. (realClass organization listAtCategoryNamed: category) collect: [:sel | | parseTree | parseTree := ( realClass >> sel) parseTree. (replacer executeTree: parseTree) ifTrue: [ realClass compile: replacer tree newSource " [1] " ] ] Now some questions: 1) In [1] "( RBClass existingNamed: className ) compileTree: replacer tree" would be more appropiate? I get a MNU when evaluated with latest AST/Refactoring. 2) The above script have some problems, if you want to get replaced 'this is a string' asString. to 'this is a string' asText it won't match. The same happens with: " self model asString " and other patterns. How to modify the rewriter to match oldMessage/newMessage at any point? i.e. [: tmp | anObject1 blabla1 blabla2 oldMessage blabla3 ] Thanks in advance, -- HernÃ¡n Morales Information Technology Manager, Institute of Veterinary Genetics.

GUI confused

by Jeff Gray

I've been looking at the UITheme examples such as exampleBasicControls. I'm used to building windows (in e.g. C#) where I create a subclass of a window class and then extend it with controls and methods. Looking at the UITheme examples it is building up a window by creating an instance of PluggableDialogWindow and then calling methods to add controls. If I have a number of windows in my app would I have one class to build all the windows? How do I hook up methods? Would they be methods in this window building class? Am I missing the point? :-) -- View this message in context: http://forum.world.st/GUI-confused-tp3175361p3175361.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi, and in order to get a minimum of dynamic pages, (I think Seaside will be too large for my memory) what is best to get simple Smalltalk server pages, swazoo or Komhttpserver ? Annick Fron

Re: [Pharo-users] Minimal pharo

by Mariano Martinez Peck

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 >

Re: [Pharo-users] Telnet client

Finding old ( and sometimes new ;-) ) Squeak code is a bit of an art. I find the Nabble search of all Smalltalk mailing lists (or you can restrict to sub groups/lists e.g. just Pharo) the best starting point (http://forum.world.st/) Searching on "telnet" produced a link to the code for the Telnet project you found (the thread is called "Net::Telnet equivalent"). Also, a google search on "squeak smalltalk telnet" produced the following additional leads: * Download some old images; "December 2004... Squeak has built in a very basic telnet client" http://wiki.squeak.org/squeak/1523 * look at the Curl plugin; "adds an new repository type that uses the Curl Plugin... supports TELNET http://www.squeaksource.com/monticellossl" HTH, Sean -- View this message in context: http://forum.world.st/Telnet-client-tp3171716p3172111.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Telnet client

by Aidan Gauland

Hi, I want to create a MUD <http://en.wikipedia.org/wiki/MUD> client (a client for games played over Telnet) with Pharo, but I'm stuck on how best to use Pharo as a Telnet client. I've heard of the cURL plugin, but I'm not sure if that can be (easily) used for anything other than file transfers. Even if I built and installed it, I'm not confident I'd be able to tell for certain whether I can use it in the way I want. I also found this <http://map.squeak.org/package/14bcecc6-dbb8-4866-bb0c-25278ca882ba>, but that's about eight years old and its homepage link is dead, so it doesn't look too promising. I found TelnetProtocolClient in the Pharo image, but that does not seem to be at all what I need. Can someone with experience with telnetting from within Pharo/Squeak point me in the right direction? Thanks, Aidan

There is issue 2610, but it is 'closed'. The closing comment, by marcus.denker, is: "I think this has been fixed in 1.2" I can't tell if it is fixed on 1.2 cos I don't know how to turn this behavior on? What setting is it? I can reproduce it on 1.1 with these steps: 1) Open the the Transcript window 2) Open a Shout Workspace 3) type a ( or [, (or any of the special characters that automatically display the 'closing' character), then move the cursor with the right or left arrow key The numbers that show up in the Transcript are the column positions of the characters.
