[Pharo-project] Why Smalltalk ? Which Smalltalk ?

by Sven Van Caekenberghe

I just came across these and I think they are very well written. Why Smalltalk ? http://smalltalkzen.wordpress.com/2010/12/20/why-smalltalk/ Which Smalltalk ? http://smalltalkzen.wordpress.com/2010/08/24/which-smalltalk/ I agree mostly with both pieces, they express reasonably well how I see things. I don't know the author's name though... Sven

Re: [Pharo-project] short circuit or redirecting selectors

by StÃ©phane Ducasse

There is an implementation of memento in magritte if you want to get some inspiration. > Which works for a normal model object. But a facade wouldn't be storing it's values in instance variables. It would be proxying for one or more underlying model objects and so would a copy of that object. So rather than have the memento just be a simple copy of the object, A memento does not have to be a copy, it can just have the same api and store the info in a dict and once validated update the model. > I want it to be a copy of the object and intercept the relevant accessors (I have a list) and redirect them to a dictionary. Then after validation, etc. the updateRefModel selector on the memento would update the underlying model or facade. Thus it would work for both normal models and facades. you can compile on the fly new methods and use instVarAt:.... but I would not use meta programming in simple model. Stef > > Elliot

Hi Alex, One source of problems is that, as you are on a Mac, you have an outdated plugin (it is from April 1, 2007). It would be nice if the Mac VM shipped with an up to date plugin... You may also find the recent status report of Dave Lewis, which he posted to this list on December 1, useful.

Currently I have: IFBaseModel >> memento | memento | memento := self copy. memento refModel: self. ^ memento. Which works for a normal model object.

Re: [Pharo-project] Unsubscribe get internal server error

by Mariano Martinez Peck

Remember you can always configure the mailing list (in mailman) so that you don't receive any message at all (but not unsubscribe). I sometimes do that for certain mailing lists at certain times (when I usually know that after I may want to receive emails again). cheers mariano On Mon, Dec 20, 2010 at 9:11 PM, Marcus Denker <marcus.denker(a)inria.fr>wrote: > Hi, > > I will open a ticket with the sys-admins... it seems the mailman interface > is broken. > (even for me as the mailinglist admin). > > What you can try is to use email to unsubscribe: > send a mail to > > pharo-project-request(a)lists.gforge.inria.fr > > with > > unsubscribe > > in the body of of the mail. > > Marcus > > > > On Dec 20, 2010, at 9:02 PM, Nick Payne wrote: > > As I'm going on holiday for a few weeks and don't want the mail to pile up > in my mailbox, I attempted to unsubscribe at the address given when I joined > the mailing list ( > http://lists.gforge.inria.fr/cgi-bin/mailman/options/pharo-project/nick.pay…) > but I just get an Apache error page: > > Internal Server Error > > The server encountered an internal error or misconfiguration and was unable > to complete your request. > > Please contact the server administrator, [no address given] and inform them > of the time the error occurred, and anything you might have done that may > have caused the error. > > More information about this error may be available in the server error log. > ------------------------------ > Apache/2.2.9 (Debian) mod_auth_pgsql/2.0.3 DAV/2 SVN/1.5.1 mod_python/3.3.1 > Python/2.5.2 mod_ssl/2.2.9 OpenSSL/0.9.8g Server at lists.gforge.inria.frPort 80 > > Nick > > > -- > Marcus Denker -- http://www.marcusdenker.de > INRIA Lille -- Nord Europe.

Re: [Pharo-project] Unsubscribe get internal server error

by Marcus Denker

Hi, I will open a ticket with the sys-admins... it seems the mailman interface is broken. (even for me as the mailinglist admin). What you can try is to use email to unsubscribe: send a mail to pharo-project-request(a)lists.gforge.inria.fr with unsubscribe in the body of of the mail.
