Re: [Pharo-project] Coral?

by Norbert Hartl

What is coral all about? There seems to be no documentation except a little tutorial. But the tutorial does not make much sense to me. It explains the installation of coral and the result is that you can run a script from the commandline. Well, that is possible anyway. So where is coral located. Between positioning it as a shell replacement in the mailing list and the "just runs a shell script" is a huge space where it could be actually located. Any hints are appreciated.

Few years back, we used to have a Seaside + GlorpDBX + SqueakDBX example that we used for the university thesis. However, I guess it is quite outdated and note sure if it works.

Last year, I did my own example and wrote an article about it: Reddit.st - In 10 elegant Smalltalk classes Implementing a Reddit style web application in Smalltalk Using Seaside, Glorp and PostgreSQL http://homepage.mac.com/svc/Reddit.st/ Sven

And what about Seaside for example? Few years back, we used to have a Seaside + GlorpDBX + SqueakDBX example that we used for the university thesis. However, I guess it is quite outdated and note sure if it works. But maybe we should do that. I think it is a good idea. In addition, we can use the same example for the PBE chapter. Finally, I remember an ESUG project which idea was a open source application based in pharo, seaside, glorp, etc, to use as an example/learning. I don't remember the name right now....but it would be awesome if that app could be changed to use GlorpDBX + SqueakDBX instead :) thanks mariano > ----- Original Message ----- > *From:* Mariano Martinez Peck <marianopeck(a)gmail.com> > *To:* GermÃ¡n Arduino <garduino(a)gmail.com> > *Cc:* ESUG Mailing list <esug-list(a)lists.esug.org> ; A friendly place > where any question about pharo is welcome<pharo-users(a)lists.gforge.inria.fr>; Pharo > Development <pharo-project(a)lists.gforge.inria.fr> ; The general-purpose > Squeak developers list <squeak-dev(a)lists.squeakfoundation.org> > *Sent:* Friday, March 04, 2011 7:53 AM > *Subject:* Re: [Esug-list] [squeak-dev] [ANN] ESUG supports once > againSqueakDBX > > > > On Fri, Mar 4, 2011 at 11:50 AM, GermÃ¡n Arduino <garduino(a)gmail.com>wrote: > >> Certainly all the Smalltalk community should thank ESUG by the >> continous support to lot of initiatives. >> >> > And to ESUG sponsors :) > and ESUG conference attendees...and...and..lots of people :) > > >> Thanks ESUG. >> >> >> 2011/3/4 Mariano Martinez Peck <marianopeck(a)gmail.com>: >> > We are really happy to announce that ESUG will sponsor us once again >> through >> > the ESUG Summer Talk project.

Re: [Pharo-project] Pharo on Apple App Store

by John McIntosh

I'm not sure anyone really answered the question. (a) Yes you can build squeak/pharo VM based applications for the iOS platform and distribute in the App Store. This assumes you adhere to the rules. (b) Yes you can build Squeak/pharo VM based applications for the OS-X platform and distribute in the OS-X App Store. This assumes someone wants to take the time to port the file dialog logic from Sophie to Pharo since you will be rejected if you present a Squeak file open/save dialog. Lastly you can't download MC packages to the app for doing on the fly updates, any updates have to go thru the app store. An example of alternate technology is Sparkle and Apple has rejected apps that use that technology to provide an update path. PS No I can't say I've actually attempted getting a squeak based app into the OS-X store, perhaps this summer, still that is my tea leaf reading of the situation.

What's the name of this step and when are you planning to start work on it? It's the step I'm really waiting for :) We do not know. We should continue to clean the system and the problem with source bootstrapping is that this is static in the sense that until the moment where we get a usable system we will have to trace changes in the kernel and push them back in the source bootstrap. So we want it too :) but I think that there is also a space for generating specific image based on dynamic collection. May be this one will be pineKernel :) http://uktv.co.uk/food/ingredient/aid/503745 "pignon" Stef
