[Pharo-project] Started to post Videos of "Deep into Smalltalk"
by Marcus Denker Sept. 30, 2011

Sept. 30, 2011

Hello, After a long wait... finally: http://www.youtube.com/user/esugboard#grid/user/843D1D545F9F52B6 This now has: - Extensive, great two part PetitParser Tutorial by Doru (3 hours) http://www.youtube.com/watch?v=vgiJG3Vd6KU If you ever wanted to write a Parser, this will give you a very understandable, step-by-step introduction. - Enhancing SqueakNOS. http://www.youtube.com/watch?v=u9RUmIY2Sz8 Crazy, these Argentinians... - NativeBoost: http://www.youtube.com/watch?v=Bd6mz6F167s Generate Binary code from the image. And a *very* fast FFI as an example. Guido and Javier of the SqueakNOS video above are right now busy here in Lille building something *very* interesting with NativeBoost... - FFI, an introduction by Igor: http://www.youtube.com/watch?v=fU8XRCO7MUU What is FFI and how do we use it? - and the first part of "A little Journey in a Virtual Machine" http://www.youtube.com/watch?v=FJQmjhOvjUs This has 5 (!) parts and together with the FFI presentation, this allows you to experience the very first lecture ever given by Igor Stasenko. More to come... but this already might keep interested people busy for some enternaining evenings :-) We will post all the rest step by step. The ESUG Youtube account has more stuff posted already, e.g. the talks of this years IWST Workshop and some talks of ESUG2011, and the classic talk of Doru from ESUG 2008 showing how (not) to give ESUG talks. All here: http://www.youtube.com/user/esugboard Marcus -- Marcus Denker -- http://marcusdenker.de

Re: [Pharo-project] [squeak-dev] The Trunk: Collections-eem.460.mcz
by Eliot Miranda Sept. 29, 2011

Sept. 29, 2011

Hi All, this quick hack (below) is perhaps wrong. Perhaps we should simply accept underscores in selectors period, and not query the preference. If so Scanner prefAllowUnderscoreSelectors ifFalse: [self class isBytes ifTrue: [(self findSubstring: '~' in: self startingAt: 1 matchTable: Tokenish) > 0 ifTrue: [^ -1]] ifFalse: [2 to: self size do: [:i | (self at: i) tokenish ifFalse: [^ -1]]]]. should read Scanner prefAllowUnderscoreSelectors ifFalse: [2 to: self size do: [:i | ((self at: i) tokenish or: [(self at: i) == $_]) ifFalse: [^ -1]]]. Instead perhaps tokenish should be redefined to allow underscores? I'd appreciate input from those that have thought about this area carefully (I have not).

[Pharo-project] [ANN] Pharo Glorp port release
by Guillermo Polito Sept. 29, 2011

Sept. 29, 2011

Hi! We are reaaaaally happy to announce (at last) a very very stable release of the new Glorp port :D. We've done a lot to achieve the following results with Glorp: OpenDBX Oracle: - 7 errors related to Blobs, which are not supported by opendbx. - 1 failure related to timestamp cast (and I don't understand the test intention yet :P) OpenDBX MySql: - 100% green tests :D OpenDBX PostgreSQL: - 7 errors and 1 failure related to Blobs, which are not supported by opendbx (again). OpenDBX SQLite: - 6 failures related to large objects, which are not supported by opendbx (again again).. 2 (expected) failures related to times & dates. Native PostgresV2 Driver: - 2 failures with blobs So far, some FAQs: *Â¿What is the difference between this port and the old one?* Almost 4 years of work of the VW team with tons of bugfixing (see the last 4 years release notes from Glorp for more detail :P) *Â¿How can I load it?* If you want to load Glorp + OpenDBX, you can try the following: *Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfGlorpDBX'; load. (((Smalltalk at: #ConfigurationOfGlorpDBX) perform: #project) perform: #version: with: #stable) load* Also, you can try loading only Glorp (maybe because you want to integrate it with your own database driver): Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfGlorp'; load. (((Smalltalk at: #ConfigurationOfGlorp) perform: #project) perform: #version: with: #stable) load *Â¿How did we test it?* We've tested it in Pharo 1.2 and Pharo 1.3 + Jenkins CogVms. *Â¿What's coming next?* *We are working for your happiness (?).* Hehe, our next step is to release the DBXMagritte project, which aims to allow people working in the Software business to create easy CRUD -the same scaffolding idea from RoR for example- including some of the following features: - (create a class model + magritte descriptions) from a database schema - [if you already have a descripted class model] use magritte descriptions to create a database schema - use magritte descriptions to create glorp mappings And then, you can use the same descriptions for your Seaside app, or in every magritte-friend framework you like ;) So, thanks again to ESUG for sponsoring the project :). Guillermo, Santiago, Gisela, Mariano, Esteban and Diogenes

[Pharo-project] No 'accept' menu on Samsung Galaxy tab/Pharo (was Re: New CogDroid alpha: with intent filter.)
by stan shepherd Sept. 28, 2011

Sept. 28, 2011

On the Samsung Galaxy, CogDroid with Pharo (1.4) gives me the 'mouse yellow' graphic, but following click does not give the 'accept' etc menu. It will select a menu morph. None of the buttons emulate 'mouse blue' on the Galaxy. With Cuis 'accept' is OK, and on Squeak if swapMouseButtons is disabled. With touchscreen, no shift/ctl modifiers are available. Has anyone managed a setting or snippet to make this work on Pharo? ...Stan On 18 September 2011 07:29, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > thanks dimitry > this is cool > I would like to buy a tablet for our team to try pharo on it. > What do you suggest? > > Stef > > > On Sep 18, 2011, at 6:54 AM, Dimitry Golubovsky wrote: > >> I have uploaded a new alpha of CogDroid: >> >> http://squeakvm-tablet.googlecode.com/files/CogDroid-alpha-20110918.apk >> >> Intent filtering has been added to the application.
