[Pharo-project] question about configuration
by Fabrizio Perin Feb. 19, 2012

Feb. 19, 2012

Hi all, I have a question about metacello configuration. Given the following default method: *ConfigurationOfFAMIXSQL>>default: spec <version: 'default'> spec for: #common do: [ spec blessing: #default. spec repository: 'http://www.squeaksource.com/Moose'. spec project: 'PetitSQLParser for MooseJEE' with: [ spec className: 'ConfigurationOfPetitSQLParser'; file: 'ConfigurationOfPetitSQLParser'; version: 'default'; repository: 'http://www.squeaksource.com/PetitSQLParser' ]. spec "Core" package: 'Famix-SQL'; "importers" package: 'Moose-SQL-Importer' with: [spec requires: #('PetitSQLParser for MooseJEE' 'Famix-SQL').]; "Tests" package: 'Famix-Tests-SQL'with: [spec requires: 'Famix-SQL']; package: 'Moose-Tests-SQL-Importer' with: [spec requires: 'Moose-SQL-Importer']. spec group: 'Model' with: #('Famix-SQL'). spec group: 'Model-Tests' with: #('Famix-Tests-SQL'). spec group: 'Importer' with: #('Moose-SQL-Importer'). spec group: 'Importer-Tests' with: #('Moose-Tests-SQL-Importer'). spec group: 'default' with: #('Model' 'Importer'). ]* When I ask to load default. What metacello look at: the pragma, the blessing: or the group:? It would be possible to load just the Model group? and How can I do that? Thanks a lot, Fabrizio

[Pharo-project] Modeling user event
by Hilaire Fernandes Feb. 19, 2012

Feb. 19, 2012

Hello, I want to modelise in the image events coming from user interaction with a tablet: rotation, orientation, sliding finger, multiple finger gesture. Where should I put that in pharo, which classes should I extend? I read there are some though about redesigning the event architecture. Not sure where I should catch up.

Re: [Pharo-project] TabbedPane Class/ Package / Workspace browsers
by S Krish Feb. 19, 2012

The usual multi window is always available if you the Open In Tabs option... is defaulted to false. So compose what you have in the tabbed pane and open the rest.. but even the tabbed pane can be smart to open all windows but except those that have #canOpenInTabbedPane property set to false. Scale/ Flex as you want.. but fix it for the newbies.

There is in my opinion still a lot of potential for improvement in this UI: - the UI is extremely cluttered; - the browsers take way too much space for the menu bar, the tool bar and the status bar, leaving only 6 lines of scrolling; - an immediate improvement could be made by replacing the menu bar, tool bar and the status bar by something like a stay-on-top context-sensitive inspector; - the color/font scheme doesn't allow one to see where current focus is and makes it difficult to see which tab is selected; - why are class names bold? - package/bundle column isn't wide enough: AIDA is a nice short name, but the different Cloudfork-ActiveItem subpackages would be unreadable; - tabs are not used correctly: compare on the first line WebEventHandler class with Package on the next: the grey line should be removed; - the 3D effect could be removed to get a much cleaner look and more space for content; - a scrollbar could be used that allows one to see text below it; - a find box could use a shadow label inside the box (or a looking glass); - the toolbar items are context sensitive but don't grey out when not applicable; - the toolbar icons are not distinctive enough Stephan Eggermont

by StÃ©phane Ducasse Feb. 18, 2012

Feb. 18, 2012

Hi guys we have a roadmap for Esteban and we would like to share it with you. We have extra items that we would like to see fixed and we are welcoming your feedback/suggestions. Note this is typically the way we want to work with the consortium in the future: Build an initial roadmap and refine it based on the input of the community. - A website for the consortium registration (esteban is expert on that). - This is important for INRIA and for the visibility of the consortium. We should get new members :) - Integration with SmalltalkHub - Working on fixing bugs! - Debugger fixes - Continuous bug fixing. - Improving release process: faster, more people involved, simpler. - Working on metacello repositories for each distributions (everything is there but missing last bits) - Metacello tools - Automatic release validations - Automatic validation of fixes Now the free items with probably igor involvement - Multiwindowing support - Fully working multithreaded FFI with ***Documentation*** - Filesystem fix and integration - Integration of OPAL - RPackage integration Igor related - Ephemerons - Object format - VM branding - Use of new canvas - Event cleaning So we are waiting for your suggestions.

Hi imagine that I want to bootstrap our nice kernel. I will need to somehow create a new nil, true, false, instances of new classes Undefined, True, False. Such instances will then be put on the SpecialObjectArray somehow. Now I can create a dummy object playing such roles and then use SystemTracer to substitute my placeholder with the true nil falseâ¦. or another trick to swap them. Now anybody has other ideas? Stef

[Pharo-project] Now you can use Fuel with FileSystem
by Mariano Martinez Peck Feb. 18, 2012

Feb. 18, 2012

Hi guys. Now you can use FileSystem streams for Fuel. Fuel only needs one small package 'FuelFileSystem' which has just 3 extension methods, and that's all ;) There is also 'FuelFileSystemTests' which let's you run all fuel tests using FS. If you want to do that, change FLSerializationTest >> setUp to send #useFileSystemFileStream rather than #useStandardFileStream and that's all. To install: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfFuel'; load. (ConfigurationOfFuel project version: #bleedingEdge) load: 'withFS'. An example: | sourceArray loadedArray serializer stream materializer | sourceArray := Array with: 'a string' with: Transcript with: [ Transcript show: 'a string' ]. "Create a file and serialize on it" stream := (FSLocator imageDirectory / 'example.fuel') writeStream. serializer := FLSerializer newDefault. serializer serialize: sourceArray on: stream. stream close. "Load from the file" stream := (FSLocator imageDirectory / 'example.fuel') readStream. materializer := FLMaterializer newDefault. loadedArray := (materializer materializeFrom: stream) root.
