Hi Chris, thanks! Using your swap and isSorted methods and our extreme naked objects approach ;-) I came up with a version of 7 lines: steps := 0. numbers := (1 to: 9) asArray shuffled. [numbers isSorted ] whileFalse: [flipCount:= numbers indexOf: ((SelectionMenu selections: numbers) startUpWithCaption: 'Revert up to which number?') . 1 to: flipCount//2 do: [ :n | numbers swap: n with: flipCount-n+1 ]. steps := steps + 1]. PopUpMenu inform: 'You needed ', steps asString,' steps.' Don't know, why it did not show up, Paul sent me a mail that he liked squeak and wanted to add it...so I added him here on the bcc. Anyone tried the Etoys-Version? Someone told me that it was not working for him, but I did not investigate... http://www.squeakland.org/project.jsp?http://www.emergent.de/pub/ smalltalk/squeak/projects/reverse.pr Cheers, Markus p.s. The following Python script does not work for me under OS-X. Maybe sorted() and reversed() need some library here? import random numbers = random.sample(range(1,10), 9) steps = 0 while numbers != sorted(numbers): print " ".join(map(str, numbers)) flipcount = int(raw_input("Reverse how many? ")) numbers[:flipcount] = reversed(numbers[:flipcount]) steps += 1 print "Done! That took you %d steps." % steps

Squeak/eToys manual?
by John Kershaw 13 Jul '06

13 Jul '06

Hi all, As a newcomer to Squeak/eToys I've been searching for info on helping my 9-11 year olds write 'Tamagotchi' style simulations, since I've been unable to find a straight-forward manual. There's lots of 'Getting started' materials, but nothing on getting to the next level. I signed up this 'Newbies' list but, to be honest, does parsing XMLs using the SAX or DOM models really fit into that category? Can someone point me to resources for real (3-4 weeks experience) newbies? John.

About Pier and Squeak
by Serdar Sahin 12 Jul '06

12 Jul '06

Hi, I want to install pier to my Linux server. I have downloaded pier and seaside from squeakmap, then i have saved it, then i have uploaded it to my server that image. I have started the headless squeak with that image. But it doesn't worked. I should give some commands (like wakom 8080). But i cannot write command to the headless server. I don't have any gui. So, how can i save the seaside when it works. I have started seaside with "wakom" command then i have saved it. But when i restart the seaside it did not work. In shortly, i have to write some commands to the headless server or i have to save the seaside when it works.. Thanks, sorry for my english..

Animation "Ticking" Frequency, Animations That Don't Loop.
by Greg Smith 12 Jul '06

12 Jul '06

GentleSqueakerFolk: I'm beginning to understand the fundamentals of Squeak animation, but need to know how to create something other than an animation that loops. How does one set up a branching series of animations that occur, on demand, one after a mouse click here, and another after a mouse click there - or, still another after the last animation plays? How do you trigger an animation to play only once? How can I set the "frames per second", (ticking frequency), of my animation? Thanks, Greg Smith

Re: YAXO package won't update

When you fire up the SqueakMap Package Installer from the "open..." desktop menu for the very first time, the first thing it does is update itself from SqueakMap 2.0 to SqueakMap 2.2. After that it seems to work fine. It successfully upgraded several other packages first, including VMMaker. It's only YAXO that fails. I thought I should tell somebody. Mike O'Brien

BobsUI

I am running Squeak3.8-6665full on a Squeak-3.7-7 VM, on a FreeBSD 6.1-RELEASE platform. I took the base image, opened a SqueakMap Browser, and told it to update all packages. This failed, in the YAXO package. The SMMcInstaller tries to do a fileIn from a null fileName instance variable. Is this known? Where should I report it? As far as I can tell, what I'm running is the standard Squeak release with the standard packages. Mike O'Brien

wxSqueak: How/Where do I find GUI object params, e.g., for Checkbox: style: wxNoBorder

Hi Brooks -- I already see that was not what you wanted try WxBootstrap constants and cmd-I it ( inspect it ). Steve

wxSqueak: How/Where do I find GUI object params, e.g., for Checkbox: style: wxNoBorder
by Steve Moffitt 11 Jul '06

11 Jul '06

Hi Brooks If you are looking at a browser window in the upper left pane -- above the scroll arrow is a small box if you click it a menu comes up. The first item in the menu is find class .. if you select that a dialog comes up to allow you to search for the class you are interested in. From the world menu ( click in any empty space of squeak app and a menu comes up ) and in the first third of the menu is the find method item -- you can type a method name there and it will give you all the classes that implement that method name and then you can select the one you want and that method comes up in a browser. Hope that answers the question. Steve

Hey Chris, thanks! (blush) I actually did not realize the keyboard-interface - you can actually type in the number to which you want to revert and then enter. Thanks for pointing this out... :-) Here is a slightly improved version, that keeps the "playfield" ;-) at the same place... steps := 0. numbers := (1 to: 9) asArray shuffled. [numbers isSorted] whileFalse: [flipCount:= numbers indexOf: ((SelectionMenu selections: numbers) startUpWithCaption: 'Revert up to which number?' at: Display center ). 1 to: flipCount//2 do: [:i | numbers swap: i with: flipCount-i+1]. steps := steps + 1]. PopUpMenu inform: 'You needed ', steps asString,' steps to sort the list.' Cheers, Markus p.s. I am wondering what it would take to write a version by scripting some morphs - and not exploiting the poor SelectionMenu... On Jul 11, 2006, at 9:16 PM, Chris Muller wrote: > That is great!
