Re: [Pharo-users] Slots

Hello, Actually slots are introduced so we can use them the next Pharo iteration (Pharo 4). It is difficult to use as it is, you need to change a bit the compiler so that it asks the class slots for field access byte code generation (a field being typically an instance variable) and you also need

Re: [Pharo-users] Initializing a class with a Dictionary

Hello, I think you should look at the STON framework. STON looks like JSON for smalltalk objects. Basically it does the same as your idea but instead of a dictionary it loads fields of an objects from a STON file which looks like a JSON file (a STON is kind of an extended Dictionary exported as a

Re: [Pharo-users] Block Recursion

Hello, Closures were implemented in Squeak/Pharo according to the blue book, so they were not real closures, up to 2008. Then the VM and the compiler were changed to support real closures. The code you showed should work both on latest Squeak and on latest Pharo fine. Old version of Squeak and/or

Re: [Pharo-users] Accessing DLLs in Smalltalk/V

Hello, To do what you want, there are 3 options: - using NativeBoost - using FFI from the VM - compiling your dll as part of the vm (VM plugin) NativeBoost is clearly the best option because it is the fastest, it is mostly implemented in the image so you can look at the code and it is by default

Re: [Pharo-users] Coding by sending messages

Hello, The problem is that in most cases non text editor based IDE are not user-friendly/hard to understand/hard to use. We are moving toward AST based tools software side but it will still be a textEditor for the user interface. I remember there may be something similar to what you are looking f

Re: [Pharo-users] AST method copyInContext:

By looking at the senders of #copyInContext:, I believe it is used in RBStringReplaceRule. By looking at this rule class comment, I believe it replaces a matched tree with another tree. So I guess copyInContext: is used to replace a subtree of the AST by another tree. Regards, Clement 2014-06-

Well the method with the code you give was compiled without any problem in my image (Pharo #30851 with FFI loaded with configuration browser as explained in the other thread). Perhaps this is related to your bug in the other thread where you were (probably) missing a package ? 2014-07-10 18:15
