Today I joined the pharo-users mailing list. I am a masters degree candidate in software design. I would appreciate an email from member(s) of the community that would be willing to communicate with me and give me a quick start as to how best to participate in the community.

The mails from the google tracker now go to this list: http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-bugtracker in turn, this means the traffic on the pharo-project list should be a bit more managable.

++ -- += -= ...
by Ted F.A. van Gaalen April 16, 2011

April 16, 2011

Hi there. I am probably not the first, and will not be the last person to come up with this suggestion, neverTheLess: To increment a numeric value I would like to write: aNum := 1. aNum ++. to increment it aNum --. to decrement it instead of: aNum := aNum + 1. For reasons of efficiency and readability. Why? Most, if not all, of today's computer processors ( they used to be called microprocessors :o) have INCrement en DECrement instructions, which are much more efficient than addition and subtraction instructions. (less clock cycles, perhaps even just one) Of course, the work should to be done by primitives, which directly utilizes the processor's INC, DEC instructions. So, wouldn't it be convenient to implement these ++ and --- methods in Pharo? and VM. I am not sure, but I suspect also a number of system classes e.g. in do: [:i|...] would perform better, wenn this method/ instruction is supported? ? Kind Regards Ted Currently making/learning Pharo/Seaside app.

For reference: what's aBuilder when you see <worldMenu>
by DougEdmunds April 16, 2011

April 16, 2011

When I got to methods involving menus and using pragmas, i.e., words in pointy brackets, such as , I ran across most of them using the parameter 'aBuilder'. Since there is no class 'Builder' the question becomes what is 'aBuilder'? Since the core contains somewhere around 60 classes that contain the word 'Builder', this is not easily answered. Thanks to the CollaborActive Book, there is an answer. Section 3.4 currently states: "The class WorldState builds the world menu using a PragmaMenuBuilder passed to all methods defining the pragma." So presumably, wherever there is 'aBuilder', mentally change that to 'aPragmaMenuBuilder', and you will be able to start figuring out what things like (aBuilder item: #System) order: 3.0; are talking about. For example, since PragmaMenuBuilder does not have a method 'item:' but it inherits from MenuRegistration, which does, you can look at the class MenuRegistration to figure out what 'aBuilder' is doing with #System, before whatever that is does something with order: :) -- View this message in context: http://forum.world.st/For-reference-what-s-aBuilder-when-you-see-worldMenu-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

if true...then what are you wainting for? http://www.pharo-project.org/community/contributors Send you data and nice picture :) Seriously, it is important for marketing among other things. Imagine you arrive to a new project...it is good to see that there are several contributing to it. Probably this page is not the best, but is something more.

Re: [Pharo-users] mouse buttons in Linux, deleting certain morphs
by Sven Crouse April 14, 2011

April 14, 2011

Mariano Martinez Peck: "Settings -> System -> Keyboard -> Control and Alt keys..." changes the modifier key, but I'm looking not to have to use a modifier with a multiple button mouse. Markus Schlager: "shift + middle button" does bring up the halo allowing me do what I could not before. So for any other beginners on Linux, middle button requires the use of the shift modifier key and right button requires the use of the control key or whatever modifier might be chosen from "Settings -> System -> Keyboard -> Control and Alt keys". Thanks for the replies, Sven

[ANN] Seattle Smalltalk Users Group
by Casey Ransberger April 13, 2011

April 13, 2011

A while back I asked if anyone on the squeak-dev list was in the greater Seattle area and wanted to meet up. I did get a few responses. Thanks to those who wrote back, and I apologize for the delay. I'm starting this up in part to create a venue here where Smalltalk isn't automatically out as off-topic. The idea is that it's about Smalltalk and anything remotely related to Smalltalk. In fact I'd really like this to be open to everyone who can be respectful to other people. The rest is just a bunch of implementation detail! So if you're in the neighborhood, and you think you might like to meet up with some like minded people on a regular basis, do pop over and add yourself to the list. I figure I'll work out a schedule if and when I have signups, but in general it will probably be early evenings on Wednesdays, maybe once a month to begin with. The site is here: http://www.meetup.com/Seattle-Smalltalk-Users-Group/ If anyone here is on the vwnc list and would like to pass my message along there, or anywhere else it might reach Smalltalkers in the Seattle area, I'd be much obliged! -- Casey Ransberger
