What a nonsense - why should they shutdown their site if it is valuable to provide infos and new downloads to their customers? If you want to shut down any page that is not up-to date you may have to shut down a big part of the internet. > ps: Java is no Hype.

I think mainstream is the better word here. I like Java and use it a lot. Some days I dislike it when I see how complicated things can get although there are better easier alternatives. Others feel the same which is the reason for Groovy, Scala, ... And there is no doubt about Javas and especially the JVMs place in the IT universe. But Smalltalk is (at least to me) not interesting because it is a programming language - it is interesting because it is a dynamic object system that is easily changeable (including metamodel and language itself). And Pharo should not stop changing this object system until something new and better comes out of it... Bye T.

I found a workaround. See https://pharo.fogbugz.com/f/cases/12379/Shape-is-missing-a-comment For me, the Nautilus "create a slice and commitâ doesnât work. Creating the slice from the monticello browser and saving it there does work.

Re: [Pharo-dev] [Nautilus] How to copy a method from a class to another class ?

by kilon alios

ok I think I am done with it. Tested also on Macos and it looks that it works fine. So it works fine both on Macos and Windows. Work on the same Nautilus window but also across multiple Nautilus windows. A summary of what I have done, I have created a class variable methodsToBeCopied, storing the methods to be copied marked by the copyMethod and then pasted by the pasteMethod in NautilusUI class. I have added them in the method right click menu and also I have added paste method in the class right click menu in case you have a class that has no methods and you want to paste the copied methods. The procedure works with one method but also multiple methods can be copied and also they can be pasted multiple times. So if you want to past the same methods again and again across different classes thats possible too. I decided to abandon the Paste New idea since its trivial to just rename the pasted method and I don't want to overcrowd the menus. Hope you like my code :) On Mon, Dec 9, 2013 at 2:51 PM, kilon alios <kilon.alios(a)gmail.com> wrote: > ok dont look at it, apparently it was not that either, I passed an array > to a method that expected a single object so it was my bad.
