[Pharo-project] is it possible to know the memory occupation (bytes) of an object?

by Mariano Martinez Peck

Hi. I don't know if "memory occupation" is the better name. I just want to know the amount of memory that an object is occupying in RAM. I mean, the amount of bytes. Is this possible ? if true, how ? I would like to do it from both sides: image and VM. I checked both but I didn't find anything. Thanks in advance Mariano

[Pharo-project] Class>>rename:

by Fernando olivero

Hi , please integrate this change to Class>>rename: rename: aString "The new name of the receiver is the argument, aString." | oldName newName | (newName := aString asSymbol) = (oldName := self name) ifTrue: [^ self]. (self environment includesKey: newName) ifTrue: [^ self error: newName , ' already exists']. name := newName. self environment renameClass: self from: oldName. (Undeclared includesKey: newName) ifTrue: [self inform: 'There are references to, ' , aString printString , ' from Undeclared. Check them after this change.']. I moved the (Undeclared..... ) statement to the end. To send #inform: after performing the actual change, and not before. In this way you can catch the ProvideAnswerNotification, and remove the modal dialog that pops up and still perform the actual class rename! For example... [ self performRefactoring: refactoring ] on: ProvideAnswerNotification do:[:err | " do not inform the user! " ]. Please let me know if you agree, and will integrate it. Saludos, Fernando

Re: [Pharo-project] How to copy some nice UI bits from Squeak4.1 (e.g. get rid of the fat buttons in OB)

by Tim Mackinnon

Ah - that explains it - thats a tip that I hadn't yet worked out. Thanks for pointing it out (I can see it could be useful when finding all dirty changes - but a bit disorienting when you are a new user trying to find a specific package).

[Pharo-project] SandstoneDb infos

by laurent laffont

Hi, Ramon Leon brings some clarification on SandstoneDb, good to know: ( http://pharocasts.blogspot.com/2010/04/sandstonedb-simple-activerecord-styl… ) If you'd like to avoid restarting the image when you create subclasses, you can just run SDCheckPointer startUp: true. This is what happens at image startup that ensures all the directories exist and reloads the database. Also, just FYI, you don't need to make all biz objects active records, had the tweets just been an Object subclass, they would have been save with the Person in the same file as the Person atomically. Of course, then the only way to get the tweets would be through the person, since it'd be the aggregate root for that aggregate object cluster. Anyway, nice screencast.

I noticed that in Squeak 4.1 the title bars of all browsers all seem to be native size. I am wondering if there is a similar fix? I don't know, the size of the title bar either comes from the currently selected theme or your font choice. There is no such thing as "native size" in Squeak or Pharo.

Re: [Pharo-project] [Pharo-users] RB AST serialization

by StÃ©phane Ducasse

Daniel what would be really cool is to see if we can compact/zip AST because marcus is really interested into slimbinary libraries and having a really strong compaction of AST would be an interesting basis for a lot of experience On Apr 27, 2010, at 6:45 AM, Daniel Galdames wrote: > Hi, I'm working on a serialization of a RB AST, is in a very very earlier state, it can encode simple ASTs into a string but today i changed the encode methods, so now you can't decode the generated string :-P .Some node from AST-Core can't be encoded yet (RBPragmaNode, RBArrayNode, RBLiteralArrayNode) because I'm not sure what to encode, and the nodes aren't documented, at least in Pharo 1.0. > Any comments and suggestions will be appreciated!! :-) > I uploaded the code in squeaksource: > http://www.squeaksource.com/AstSerializer.html > > I'm a bit new to Smalltalk and Pharo, so feel free to comment... > Greetings, > Daniel Galdames G. > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project

Re: [Pharo-project] [Pharo-users] RB AST serialization

by Lukas Renggli

Hi Daniel, I haven't looked at your code yet, but wonder what your goal is? How is your serialization different from source := aProgramNode source ? How is your deserialization different from RBParser parseMethod: source ?
