[Newbies] Re: Removing a method...
Le lundi 10 novembre 2008 à 02:23 -0500, Tony Giaccone a écrit : I I say yes, I get a References To: browser with pointers to other classes where a method (message?) with the same signature is used However, none of those references will ever be to my class, they are made against classes that already exists. I don't want to touch those references, but I do want to remove my method. How do I do that? It's totally not clear to me. Yep, I guess when you are using the remove method from the refactoring tools, it will just make not possible to remove the method as long as there are places where this method name (message) is used. In that case, you can just use the non-refactoring remove tool from the same popup menu. The menu item is remove...(x). When the method is selected you can also use the [alt]+[x] shortcut. You may found that you do not need to use the refactoring version to remove a method, but more when you want to rename a message. In that latter, you have to be careful to rename your message use and not ones from other method with the same name. Hum, not sure it sounds clear.

When you run an external program, it gives you a process proxy in Squeak the keeps track of the run state of the external program, as well as exit status after the program completes. However, as I said this is not cross-platform. It will work on Linux and Unix, and will work on Mac OSX if you install the plugin from unix/linux. It will also work on Windows, but only if you build your own VM and modify some of the Windows platform source, so this is definitely not for beginners ;) So on, Windows, it is best to use FFI (but I don't think you can have a blocking mode with this).

[Newbies] Re: Squeasource.com project access right
Lukas Renggli a écrit : Yes, one access right rule per project. It doesn't make much sense to assign access rules to packages as packages are no first-class entities in Squeak or SqueakSource. There are just versions of snapshots of a specific working set. The name and the contents of these versions might change with every commit. Not sure we talk about the same things. If you look a the 'Latest' link from http://www.squeaksource.com/iFichier.html you will see three different packages eFichier, iFichier and iFichierWeb. It is for these packages I want different access right, not for different versions of the same package. Yes, but from Squeak I can commit eFichier and change the filename in the commit dialog to iFichier for example. Ok, so I guess you mean it is not a good idea to have multiple packages in on project or so?
