Pharo on Windows
by Torsten Bergmann Jan. 21, 2011

Jan. 21, 2011

Looks like you use the "Pharo one click image" which is multiplatform. Why dont you use the Pharo installer for Windows which I created. - the download is smaller (you dont get the Linux/Max VMs) - it is better integrated into Windows You can find it when you scroll down at: http://pharo-project.org/pharo-download Here is the direct link: http://gforge.inria.fr/frs/download.php/27305/setup_pharo1.1-11411-release1… Bye Torsten http://astares.blogspot.com -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!

soft write barrier
by Norbert Hartl Jan. 20, 2011

Jan. 20, 2011

I'm thinking about tracking changes to objects. I had a look at WriteBarrier on squeaksource. My goal would be to have something more soft that does not need to track class shape changes and most of the system notifications, just the state of an object. A second goal is to avoid having to use primitives but that shouldn't be too hard. The objects will be materialized via http and I want to have a good way to track those changes. I can think of some approaches but wanted to ask for the clever ones :) What possibilities do you see to achieve this? thanks, Norbert

Pharo and network
by Adrien BARREAU Jan. 18, 2011

Jan. 18, 2011

Hello, I read these documents: http://book.pharo-project.org/book/networking/Socket http://wiki.squeak.org/squeak/325 but I still don't get what I want with pharo. Here is the idea: I want a socket to listen a port while pharo is launched as a deamon. I tried to test the sockets with this idea: - creation of two sockets in two workspaces - server: | server st | st := String new. server := Socket newTCP. server listenOn: 12345 backlogSize: 4. server receiveDataInto: st - client: | s | s connectTo: ('127.0.0.1' asByteArray asSocketAddress) port: 12345. s sendData: 'Hello' - the connectTo:port: fails, and I don't understand why So I have no idea ... Adrien.

TDD facilities: missing ctrl+t
by Alex Schenkman Jan. 14, 2011

Jan. 14, 2011

Hi list, I've installed the TDD-Facilities package. Pressing ctrl+t, or ctrl+r does not run the test, :-( I'm pressing it while editing a test method, in the default browser of a Pharo-1.1.1-OneClick image. Any clues on what I might be missing? Thanks again!

squeak vm without MMU
by Annick Fron Jan. 13, 2011

Jan. 13, 2011

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

Hi, I have donwloaded Pharo-Kernel 12-12229, and I have launched the PharoKernel.image. It comes under Linux with a blank window (where in Windows it is headless). How is it possible to get a real headless kernel on Linux ? Annick Fron

Finding RB parse tree rule for replacements
by HernÃ¡n Morales Durand Jan. 13, 2011

Jan. 13, 2011

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.

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
