Re: [Pharo-users] Using Playgrounds as a notepad

you need to accept the contents in order for the workspace to store your text, you can use either right click menu and accept or the shortcut that menus shows then you can get the contents as a string via ws := Workspace open. "type text and then accept it" ws contents asString On Tue, Jan 5, 2016 at 3:57 AM Andy Burnett <andy.burnett(a)knowinnovation.com> wrote: > @Dimitris > > Thanks for the Workspace idea.

And many of the descriptions there aren't terribly descriptive. If people do not value their work.... we cannot do more than what we are doing sadly Stef

@Dimitris Thanks for the Workspace idea. That is pretty much what I am looking for. However, I am struggling to get it to behave the way I want. When I type into the Workspace, and then inspect ws contents I just get an empty string. Is there a simple way to get the ws to update its contents so that I can access it? @Sven, @Doru. Thanks. The Clipboard approach is very slick. I will use that for the time being. Out of curiosity, is it possible to access any other data on the clipboard. For instance, if I copy a pictured from my desktop, is that accessible via the Clipboard object? I only saw text oriented methods. Thanks Andy

Re: [Pharo-users] Interogation about recursivity or sequential

Wouldn't it be better to improve the current (Double)LinkedList instead of creating new ones? DLL had some improvements recently and I am not aware that it's missing something.

Re: [Pharo-users] Dolphin Smalltalk open-sourced...

I looked into moving source back and forth, and found an implementation of Smalltalk Interchange File (SIF) by Eric Arseneau from the year 2000. The Squeak version files in on Pharo 4 (and Squeak 5) and files some code out successfully (after a small change in symbol handling). Similarly the Dolphin version files in but fails to import a Squeak file-out, because Dolphin doesn't understand {} in Dictionary class>>newFromPairs:. Next step is to look at the compiler I suppose. Down the rabbit hole... SIF is found here: http://www.pocketsmalltalk.com/sif/. Pocket Smalltalk, now that's a very cool thing. Pierce
