But how do we do in practice? Classes know how to create their own subclasses, by having subclassed from Behavior. Behavior-class is the meta-meta-object you seek, instances of which will know how to create objects and subclasses. In fact, the textual "class definition" (from the "instance" button in the class browser) is nothing other than smalltalk code that creates that class! You can look up that method in Behavior class to see what it does. -- Randal L.

[Pharo-project] object that create other objects [meta-object]?

by magique poter

Hello, First sorry for my bad english. I will try to be understandable:) I have a problem that is, I think, enouth interesting (and difficult to found responses on the web) to post here. I hope somebody will understand it, and point my attention to some keywords, or web links. Here is my interrogation: - in smaltalk, everything is object, - i create classes whith the browser (an object), - then there are objects in smalltalk that create classes. Question: - What are the keywords, the technologies I will have to deal with to create that kind of objetcts (object that create classes that I can then initialize to create instances)? - After lot of search, the thing I want to create seams to be a meta-object. But how do we do in practice? - Do you have some books to recommand to understand this programming practice? Thanks in advance. Best regards

Great! I did a few clean up in the gettext package, check if it is ok. Still some Pharo core classes and methods need to be changed.

Re: [Pharo-project] Remove developing with Pharo

by Andrei Stebakov

That's right, looks like it sends full-blown images (not the delta, not the commands to x-server) and re-drawing takes forever. I wonder if it's a Pharo issue or x-server's? My xterm works pretty fast compared to Pharo though... 2010/5/12 Schwab,Wilhelm K <bschwab(a)anest.ufl.edu> > I have at times done what you are attempting, and painful is nicest > adjective I can think to use.

[Pharo-project] rename a symbol

by Sean Allen

is there a way to do a refactoring that takes all instances of a symbol and renames them? So if I had a symbol #Foo in a method, rename it and all other uses of #Foo to #Bar.

[Pharo-project] Issue 2420 and fix in inbox (alain can you check?)

by Mariano Martinez Peck

Alain: we should check if these problem is not present in another place. Fix in Inbox: Name: Morphic-MarianoMartinezPeck.584 Author: MarianoMartinezPeck Time: 12 May 2010, 7:42:50 pm UUID: 33b351fa-fc71-4ae1-8e7b-019570597208 Ancestors: Morphic-StephaneDucasse.583 Fix to issue Issue 2420 WorldState >> mostUsedToolsOn: is hardcoded to use StandardToolSet. When using another ToolSet, like the case of the Dev image, the most used tools still uses StandardToolSet instead of DEVToolSet. It need to be changed to use "ToolSet default" instead.
