NBFFI version of the OpenDBXDriver
by Rocio Amaya Sept. 12, 2013

Sept. 12, 2013

* Hi! I'd like to show a bit the outcome of the first iteration of the DBXTalk Gsoc of this year. First, I've been adapting myself to the environment and technology (DBXTalk, OpenDBX, TalkFFI), and I've written some little tutorials of what I've learnt about them: - Post of how to install OpenDBX http://rochiamaya.wordpress.com/2013/07/28/how-to-install-version-1-4-6-of-… - Post of how to install and use TalkFFI to generate mappings http://rochiamaya.wordpress.com/2013/07/30/create-bindings-with-talkffi/ - Post of how to use mappings generated by TalkFFI http://rochiamaya.wordpress.com/2013/08/06/how-to-use-the-generated-binding… Also, as concrete code, we have built a NBFFI version of the OpenDBXDriver. The main idea of this is to provide a backward compatibility layer to people that use OpenDBX, while letting us move forward dropping the old FFI implementation. Gofer it smalltalkhubUser: 'DBXTalk' project: 'Configurations'; configurationOf: 'OpenDBXDriver'; load. (((Smalltalk at: #ConfigurationOfOpenDBXDriver) perform: #project) perform: #version: with: â1.3â) load: 'DeveloperGroup'. However, the configuration still supports to load the former version of the driver (no NBFFI) Gofer it smalltalkhubUser: 'DBXTalk' project: 'Configurations'; configurationOf: 'OpenDBXDriver'; load. (((Smalltalk at: #ConfigurationOfOpenDBXDriver) perform: #project) perform: #version: with: â1.3â) load: 'FFIDriver'. And the configuration with only NBFFI version. Gofer it smalltalkhubUser: 'DBXTalk' project: 'Configurations'; configurationOf: 'OpenDBXDriver'; load. (((Smalltalk at: #ConfigurationOfOpenDBXDriver) perform: #project) perform: #version: with: â1.3â) load: 'NBFFIDriver'. To use, writte in the Workspace and DoIt: âto set the NBFFI bindâ LibOpenDBXMap initialize. OpenDBX current: NBPharoOpenDBX new. âor to set the oldFFI bindâ OpenDBX current: FFIOpenDBX ffiImplementationForOS . In our current/next steps, we are starting to dig into the other driver implementations. I'm currently working in a Mysql driver implementation that will use the C mysql library directly without the intermediation of OpenDBX. That way, the setup of the environment will be far easier and the entry barrier will be lowered. Best Regards! Rocio *

Group and member with Voyage
by Esteban A. Maringolo Sept. 11, 2013

Sept. 11, 2013

Hi all, Let's say I have a class Group and a class Member. aGroup has many members. and aMember can belong to many groups. What is the "proper" voyageDescription for those one to many relations? Should I do something extra? Everytime I add a member to the group, both the member and the group get their references updated. Now when I add a member to a group and save it, I also save the member. Is there another way to avoid this? Any recommended practice for this? Next level question: What if it gets composite? it is... a Group has other Groups as members :) Regards! Esteban A. Maringolo

The objective of this work is to contribute to the refactoring and improve the (VW written) Biniou Framework (modelling Embedded reconfigurable devices to produce software development environments). Biniou is currently being extended with new features and requires to define a versioning and testing policy. > > - Phd : Start January 2014 > > > In the scope of the FP7 ERATO project, the PhD student will contribute to set up a Professional environment to exploit a new European FPGA (reconfigurable device) dedicated to space application. > > One important contribution will be to expose a manipulation API to application Designers while protecting the hardware intellectual property.

Lets Talk about Pharo Help tool
by Torsten Bergmann Sept. 10, 2013

Sept. 10, 2013

Kilon wrote on "Pharo dev-list" >So my attention came to help tool, I think I get how it works, I started >making the documentation with it, questions is if there is anything more to >it than the functionality I am seeing in the Help docs. Maybe a third party >lib that adds more features ? > >Is there a plan to extend it ? Some time ago I created the "old" in image help tool so one can easily access help directly from the image. It was accepted and integrated into the standard image. It is usable and some projects/packages use it. But since media is (by default) not yet that rich within Pharo and mostly people also would like to see the documentation on the web I created a successor called "PharoOnlineHelp". This also allows you to be more independent with your docu from the help system itself. The new help system: ==================== - is called "Pharo Online Help" - uses only a single "marker" pragma - supports markdown - can be viewed/served online - is not part of the standard image but can be easily loaded How to use it: ============= - take a fresh Pharo 2.0 image from http://files.pharo.org/platform - open the config browser (Tools -> ConfigurationBrowser) - select "PharoOnlineHelp" from the list and easily install it - now in menu "Help" you will find "Help server", click on "Start server" on the control panel - if you are on Windows you can click on "Browse" to open a browser, in any other case go to http://localhost:8080 with your web browser You can now click and browse the available docu that is in the image. It also has an API help and links to most Pharo resources. If you want to extend the "Intro" tutorial section for instance with a "Native Boost" tutorial you can: - create an own class as subclass of Object in your own package - implement a class side message with a pragma #onlineTutorial nativeBoostTutorialOn: aBuilder <onlineTutorial> (aBuilder tutorial: #'Introduction to NativeBoost') description: 'An overview and introduction to the Native boost interface'; addLesson: ... - see class "PharoTutorial" for an example or this picture: http://lists.gforge.inria.fr/pipermail/pharo-project/attachments/20130224/9… NOTE: the tutorials are written in Markdown, so you can: - write a blog post or website with a tutorial and later aggregate it/link to it in Pharo online help - use and embed rich media like youtube videos, web pages, ... - use Markdown editors like http://dillinger.io/ to write the docu Hope this will answer your questions. You can use the old help but I would rather like people to see jumping to the new online help. Bye Torsten

Where can I get Pier?
by James Foster Sept. 10, 2013

Sept. 10, 2013

http://www.piercms.com/download contains a couple links, each of which seems to have a very nice install of Seaside but Pier is absent! A month ago I got a nice Pier image from that link. Attempting to load ConfigurationOfPier3 gives this error: 'Could not resolve: ConfigurationOfZincHTTPComponents [ConfigurationOfZincHTTPComponents] in /Users/jfoster/cloud2/pier3/Pier.app/Contents/Resources/package-cache http://mc.sftx.eu/ZincHTTPComponents ERROR: ''GoferRepositoryError: Could not resolve the server named: mc.sftx.eu''' Attempting to load ConfigurationOfPier2 gives this error: 'MessageNotUnderstood: Form>>capitalized' Anyone got a decent Pier image in Pharo that they can share?
