Oh I have little doubt I am going to regret in many painful ways :D but certainly having someone to offer at least some good advice can go a long way. So yes I am not kidding myself :D But I have come to realise in my life that none of the really fun things in life is easy so I am certainly diving in.Â Thanks Igor you already have helped me more than once getting through smalltalk code and not only. The good news is that you are an open and friendly community that welcomes contribution even from noobs like me and I think that is motivation by itself. ________________________________ From: Igor Stasenko <siguctua(a)gmail.com> To: Pharo-project(a)lists.gforge.inria.fr; dimitris chloupis <thekilon(a)yahoo.co.uk> Sent: Sunday, 25 November 2012, 16:10 Subject: Re: [Pharo-project] Athens OpenGL backend - what does it mean? .. and you can count on me in your quest for excellence :) On 25 November 2012 15:02, dimitris chloupis <thekilon(a)yahoo.co.uk> wrote: > "eye candy" wise this is exactly the focus of my Ephestos project , Morpheas > section.

[Pharo-project] [Ann] 4.7 beta
by Tudor Girba Nov. 25, 2012

Nov. 25, 2012

Hi, As a result of the successful Moose Dojo that took place on November 15-16, Moose 4.7 entered the beta state. Some of the outcomes of the Dojo are: - Cleaned a couple of hundred obsolete FAMIX navigation methods (by Robert and Nicolas) - Fixed the major bug when editing code (by Andrei and Stephan) - Fixed several other Glamour bugs (by Erwann) - Worked on improving the PPAllParsersBrowser (by Jan) - Got the GTDebugger to start to work with Bifrost (by Jorge and Andrei) - Got Reloader almost ready to work with Metacello and produce a reloadable version of the complete Moose (by Stephane and me). The 6 remaining issues are listed on the issue tracker: http://code.google.com/p/moose-technology/issues/list?q=milestone%3D4.7 Of these, the most important are: - http://code.google.com/p/moose-technology/issues/detail?id=869 (an unfortunate side effect of getting the code editing fast) - http://code.google.com/p/moose-technology/issues/detail?id=865 (we need to find the way to get the proper loading order of all packages) Anyone want to join efforts on these? Ideally, we should release somewhere at the beginning of December. Afterwards, we move to Pharo 2.0. Cheers, Doru -- www.tudorgirba.com "In a world where everything is moving ever faster, one might have better chances to win by moving slower."

[Pharo-project] Re; About new TxText text model
by Stephan Eggermont Nov. 25, 2012

Nov. 25, 2012

Hi Igor, The TxText model to me seems to mix two concerns. The storage of the text and manipulating it? Both cursor positioning and selection manipulation are view dependent, and there might be more than one. Stephan

[Pharo-project] Pharo 2.0 on Raspberry Pi ?
by Sven Van Caekenberghe Nov. 25, 2012

Nov. 25, 2012

Hi, Does anyone know how to make Pharo 2.0 run on a Raspberry Pi ? I am running an up to date 2012-10-28-wheezy-raspbian (Linux raspberrypi 3.2.27+ #250 PREEMPT Thu Oct 18 19:03:02 BST 2012 armv6l). There seems to be a Stack VM on it, it does run Smalltalk code, but there is some initialization error, a loop of VM: unix - armv7l - linux - THERE_BE_DRAGONS_HERE MessageNotUnderstood: receiver of "do:" is nil 22 November 2012 8:55:09.996 pm in PharoDebug.log. I will (try to) look deeper into this, but if someone knows how to get things working, I would be grateful for any help. It would be really great if we as a community would be able to offer this as an option. Thx, Sven PS: I specifically want to run a (possibly patched) Pharo 2.0 image, not something else. -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] NativeBoost callbacks - status?
by Ciprian Teodorov Nov. 25, 2012

Nov. 25, 2012

Hi Igor, What is the extent to which callbacks are currently supported in NB? On my machine (macos10.6) they do not seem to work properly. The quick sort test crashes the VM. What are the limitations of the current implementation? Thanks Ciprian

yes! But not only it would enable having multiple windows, because now we "downgrade" all the events to the minimum common denominator, and pass a "raw event" captured from each OS, from the vm to the image. would be nice to do some surgery on the vm, and cut the windowing management and raw event handling away. It belongs in the image, if it can be implemented using NB to the OS UI frameworks, or in a separate app. We just need a surgeon with the time and ability to do soâ¦.i've tried in the past and the related VM code was really hard to understand. Fernando pd: There were some discussion around this idea last year in the mailing list.

[Pharo-project] MongoTalk update
by Nicolas Petton Nov. 25, 2012

Nov. 25, 2012

Hi guys, Lately I worked a bit on the Pharo Mongo driver for SmalltalkHub. I made several changes (in the new version 1.4): The query API changed: - MongoCollection>>query: now takes a 1 arg block, improving the API quite a bit. Queries like: aCollection query: (aCollection query query: { 'foo' -> 'bar'} asDictionary; yourself) Is now written: aCollection query: [ :query | query where: { 'foo' -> 'bar'} ] Sending #asDictionary has also been made optional, the query builder will send #asMongoQuery to the query collection. The MongoQueries package: Version 1.4 comes with a new package MongoQueries, a small DSL allowing us to use traditional blocks instead of dictionaries to perform queries. This is optional and backward compatible. Queries like: aCollection select: { '$or' -> { 'name' -> 'foo'. 'age' -> { '$gt' -> 23 } asDictionary } asDictionary } asDictionary can be expressed: aCollection select: [ :each | (each name = 'foo') | (each age > 23) ] The MongoQueries package should support the entire mongo query language (including nested queries), and comes with unit tests.

[Pharo-project] [ANN] Limbo: a simple shell wrapper for NativeBoost
by Max Leske Nov. 24, 2012

Nov. 24, 2012

Hi everyone. I want to announce the first (and *very* basic) version of Limbo. Limbo is a simple wrapper around NativeBoost that lets you run commands on the shell (via sh) or directly (no shell expansion). To use Limbo you will need the NBCog VM and install NativeBoost into your image (with "NBInstaller install"). You will also need to build the shared library from the archive attached to this e-mail and put it into the "Plugins" directory of the VM (instructions inside the archive). I also attached the xcode project. The Limbo repo: MCGemstoneRepository location: 'http://ss3.gemstone.com/ss/Limbo' user: '' password: '' I am *not* an experienced C coder so there might be some horrible stuff in the box. If you have any suggestions / requests / bug reports or would like to contribute, let me know. Disclaimer: NativeBoost uses direct memory access. I have written Limbo to the best of my memory layout knowledge (I'm quite a n00b there) but cannot and will not guarantee that you might not experience memory leaks or VM crashes (or any type of crash for that matter). This is just a warning, I haven't had any troubles at all with Limbo so far. Cheers, Max
