Re: converting arrow to ':=' for assignment in squeak 3.9

What I did for Magritte, Pier, Seaside, Scriptaculous and many other packages was: FixUnderscores fixPackage: 'Magritte' This fixes all the assignments automatically and opens up an editor on methods that couldn't be automatically fixed. It is a matter of minutes to even clean up huge projects. Cheers, Lukas -- Lukas Renggli http://www.lukas-renggli.ch

converting arrow to ':=' for assignment in squeak 3.9
by Ralph Boland 01 May '07

01 May '07

I am currently converting my squeak project from Squeak 3.8 to Squeak 3.9. (Thanks by the way to the people who helped me installSqueak 3.9 in Linux. Note that commands 'man squeak' and 'man inisqueak' still reports the existence of a command 'inisqueak' even though the command is not to be found.) My understanding was that as of 3.9 Squeak no longer supports use of the arrow for the assignment operator and that I must use ':='. :-( I thus expected that all my arrows would be converted to ':=' upon fileIn. But this doesn't happen. Upon investigation I found the the arrow operator still in use in the 3.9 code though it is now displayed as an underscore (which after all is what is is). Can someone explain to me clearly the status of the underscore character for Squeak 3.9 and beyond? Can someone explain to me how to convert my underscores to ':=' or must I write a sed script to do this? Note that I will use the arrow until I am forced to convert to ':='. Thanks Ralph Boland P.S. I am running Squeak3.9 on Ubuntu 6.10 Linux on a PC.

Held an OLPC laptop today!

Bert Freudenberg brought the OLPC laptop to dinner before Smalltalk Solutions 2007 in Toronto. That gave me and about 20 others at the dinner to touch and play with the laptop for the first time. We had some fun opening it, I think the 6th person suceeded. I have to say, it is every bit as beautiful as in the pictures I have seen and more. There are some unusual buttons both on the keyboard and on the laptop and the UI is a bit different from the Qemu version I played with last. Everyone had a chance to look at it or play, Vicki Ross created her first eToy animation in about 5 minutes. EToys feel almost the same speed as on and Athlon 2400 on which I am writing this which is great. One thing I realized trying to build a quick presentation, is that we really need a different interface then the mouse pad or mouse. This is beside the point and not the OLPC fault, the mouse pad works pretty well, but really,mouse is an OK interface for *navigation* and copy/paste of text, but not very good for *manipulating* and building things - and eToys are very much about building. I wish someone could think of a better device after all those years... perhaps something that one can hold in hand, not flat, maybe similar to joystick, or sort of a piece of squishable/moldeable piece of clay-like material, well, not sure... I believe we will have a chance to see the laptop on display at the Squeak booth during the conference. Thanks Bert for bringing it over, it really is even nicer then I thought! Milan
