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

Pharo Kernel

by 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

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, I have tried the minimal pharo, yet on Linux it opens a blank window. How is it possible to get rid of it ?
