[Pharo-project] SmalltalkHub news
by Nicolas Petton Nov. 10, 2011

Nov. 10, 2011

Hi, We've been very quiet about SmalltalkHub's development since ESUG 2011. It's not that we didn't work on it, but there was no significant new feature to show. Part of the work was to make SmalltalkHub run smoothly on GemStone/S as well as under Squeak/Pharo, and allow pluggable persistency strategies instead of the hard-coded SandStoneDB persistency. We also took into account all the feedback we got and implemented several of the asked features and fixed reported issues: - RSS feeds for project activity and commits - markdown fixes - issue tracker improvements - better looking and more useful timeline events - loading indicators when necessary - project cloning fixes We are currently preparing a public demo of SmalltalkHub. It should be online after this weekend. This demo will be running on GemStone/S, will have many UI improvements and the usual bug fixes. Some features like project cloning and the scripting engine may not be available depending on the time we get. Cheers, Nicolas

[Pharo-project] FW: Brainstorming on the roadmap for first Pharo Consortium Engineer :)
by Schwab,Wilhelm K Nov. 10, 2011

Nov. 10, 2011

[This appears to have bounced - trying again] Ben, That's an interesting idea. I'm sad to say that we would need to think about security in the receipt of data. Just as we now have signed license agreements, we might need to have certificates and keys for publishing test results. Passwords might be sufficient and easier to manage. An existing server would likely end up with a Seaside app that allows mere mortals to request a signing or a password. After moderator approval (also part of the app), the tester would be given or emailed to retrieve the credentials needed to post test results. BTW, none of that makes it a bad idea or "too hard." I just fear that we would regret having a wide-open way to trash our test results data.

I would personally be happy to contribute cpu cycles to running a Pharo test system on top of a virtual machine, which from a central server obtains a random set of Metacello configurations to install, runs tests and reports results to the central server. Apart from gaining the processing power to possibly test all permutations of configurations, it also provides a way for new community members to feel like they are contributing, which preceeds them getting more involved. As an example in line with my first comment, perhaps the initial proof of concept would be done as a research project, and then the paid professional would polish off the stability and usability of it. cheers, Ben

[Pharo-project] NewTextMorph
by Hilaire Fernandes Nov. 10, 2011

Nov. 10, 2011

I want to plug a multiple line text morph a DrGeo canvas. The morph should display the text (yes) and be editable on place when the user ask for. Which class should I use ? EditableTextMorph, EntryFieldMorph or NewTextMorph The comments of the class EntryFieldMorph wrote about example1 and example2 methods bit I dont see it (I am using Pharo 1.3) Hilaire -- Education 0.2 -- http://blog.ofset.org/hilaire

[Pharo-project] new Cog VMs are available
by Eliot Miranda Nov. 9, 2011

Nov. 9, 2011

Hi All, the VMs are available at http://www.mirandabanda.org/files/Cog/VM/VM.r2508. CogVM source as per VMMaker.oscog-eem.137/r2508. Fix primitiveContextAt[Put] for non-contexts (ContextPart subclasses other than MethodContext including BlockContext). stObjectAt[Put] could fail so args should be popped only on success. Fixes failures in ClosureCompilerTest>testSourceRangeAccessForBlueBookInjectInto as of VMMaker.oscog-eem.118. Add convenient shortPrintFrame:AndNCallers: for debugging. Make the unix launch script include /lib & /usr/lib in LD_LIBRARY_PATH if LD_LIBRARY_PATH is unset. Modify the invocations of ex in the editing scripts to not read ~/.exrc, and hence not be confused by e.g. set ignorecase. Fix error codes for at: and at:put: primitive so that for non-indexable objects they fail with #'bad receiver', not #'bad index'. Filter-out attempts to create MNU pics with new selectors. Fixes Stephane Rollandin's crash of 21/10/2011: [((Compiler new evaluate: ('Beuh' ifNuk: [yo])) on: Error do: [:ex | ex description]) printString] fork -- best, Eliot

[Pharo-project] caputriing redButtonPressed and controlKeyPressed
by Hilaire Fernandes Nov. 9, 2011

Nov. 9, 2011

In the code bellow, redButtonPressed and shiftPressed are detected correctly. However if I replace the #shiftPressed message by #controlKeyPressed message the redButtonPressed and Control key can not be detected *at the same time* Indeed, if I remove the redButtonPressed test, ControlKeyPressed is detected. All in all, it looks like redButtonPressed and ControlKeyPressed cannot be captured at the same time. I am under Linux VM. Is it an known problem?

[Pharo-project] KeyboardEvent differences between platforms
by Guillermo Polito Nov. 9, 2011

Nov. 9, 2011

In TextEditor>>initializeShiftCmdKeyShortcuts the shortcuts are set in a way that it creates three handlers for each shortcut to make it work xD. The main difference here is that in Linux, ubuntu 11.04 the Ctrl+a comes with the right keyCharacter, but in Windows and MacOS it does not :(. We've tested that on host OSs with friends :). I've captured the problem I'm experimenting so far and wrote down an ugly hack in this method. KeyboardEvent>>modifiedCharacter self flag: #hack. "Hack me. When Ctrl is pressed, the key ascii value is not right and we have to do this shit" ^(self controlKeyPressed and: [ (#(MacOSX Windows) includes: Smalltalk os current platformFamily) and: [ keyValue <= 26 ]]) ifTrue: [ (self keyValue + $a asciiValue - 1) asCharacter ] ifFalse: [ self keyCharacter ] But I'd like to replace that by: KeyboardEvent>>modifiedCharacter ^self keyCharacter :P Are there any technical reasons why the Sensor behaves like that? How difficult is it to make it work the same for all three vms? Thanks! Guille

[Pharo-project] About implementors and senders
by Guillermo Polito Nov. 9, 2011

Nov. 9, 2011

Hi! http://code.google.com/p/pharo/issues/detail?id=4547 That is a bug entry about the implementors and senders behavior when selecting this or that in different GUIs. So, I think the whole UI has to be rethought (in little steps), and arguing about this is healthy. So, the places where searching implementors and senders today should be: 1) a text editor 2) a message/method list 3) an inspector ? 4) ? 1) In a text editor the behavior is obvious for me :) 2) This is the discussion in the issue. The browser asks about senders/implementors of messages sent in the selected method. The senders/implementors browser just browses again the message. I think that searching the implementors of #something while I'm browsing the implementors of #something has no sense, hehe. But the other behavior (the one in the browser) does not convince me either... 3, 4 and etcetera) I'm not sure about anything, hehe. Cheers, Guille

How do we create a seamless loading experience for people that have not been keenly following the Metacello & Pharo lists for the last year? If I downloaded Pharo today, where's the central access point I would go to load something? Things seem scattered - Metacello configurations can all be found in MetacelloRepository... unless they are with their projects... or both, with one or the other out of date. Loading scripts are often posted to the list, but do they ever get captured into a configuration? It's embarrassing, but I didn't even know about Metacello's Toolboox API unless I read the beta chapter from PBE2 yesterday - I thought configs all had to be coded by hand! - so I never quite "had the time". What can we create to tighten up this process and empower (especially new) users?
