Next, put this in the file repl.st: OSProcess thisOSProcess stdOut nextPutAll: 'Welcome to the simple

Directly injecting a hanlder into Comanche or Swazoo? Sebastian N. I would like to share what I think is more up-to-date information (as of end of 2012).

问题 With every new Squeak/Pharo image, I immediately change the fonts to some native version. It is a lot of mouseclicks and I want to script the process. 回答1: The above answer might be outdated by now, at least it doesn't work with my 3.10 image. so, I use this: defaultFont := LogicalFont familyName: 'Geneva' pointSize: 10 emphasis:0 . codeFont := LogicalFont familyName: 'Monaco' pointSize: 10 emphasis:0. Preferences setCodeFontTo: codeFont. Preferences setWindowTitleFontTo: defaultFont.

How can I add a new item - Workspace openLabel: 'Workspace' - to the World-menu of Pharo 4.0 ? (What can I say... I prefer Workspace over the new what's-it-called. :-) I've looked at several menu-related items in the Browser, but couldn't really make head or tails of it. I also tried to find where the menu is stored (it must be somewhere, right?), but couldn't find it. Also, how would I go about to add it to one of the existing sub-menues of World-menu, and how could I create a new sub-menu (in the World-menu) and add it there?
