[Pharo-project] Fwd: [squeak-dev] Updated trunk image
by StÃ©phane Ducasse Nov. 30, 2009

Nov. 30, 2009

Hi guys I would really like that we have a look at the squeak improvement lists and see the ones that could be interesting for pharo. Note that some of them are already included in pharo.

"self-evaluation" as a concept has been removed since every object can be forced to be self-evaluating by asking for its storeString. > > Projects > -------- > Project refactoring are an ongoing process.

This removes a huge amount of dependencies between the tools and particular UI frameworks, and puts all the UIs on equal footing (there were several tools that were either not all or only partially supported in MVC before). > > New Text Editors > ---------------- > A complete new set of text editors (Editor, TextEditor and SmalltalkEditor) are available. They replace TextMorphEditor and break one of the last hard links between Morphic and MVC. With the new editors it will finally become possible to have Morphic be self-contained without the need to rely on portions of MVC. > > Morphic Text Improvements > ------------------------- > Morphic has now regular blinking insertion point cursors instead of the (virtually invisible) static cursor previously. In addition, various problems with mixing fonts and the heights of text have been fixed. > > Preference Pragmas > ------------------ > Preference pragmas simplify dealing with preferences by providing automatic discovery for preferences defined in your classes. No more littering Preferences; you can now define preferences local to your class and store the values in regular class variables. The preference gets automatically discovered by using the <preference:category:description:type:> pragma. > > Beautiful, Anti-Aliased Fonts > ----------------------------- > We have a new set of beautiful anti-aliased Deja Vu bitmap fonts in this image. The default sizes include 7pt (for handheld devices), 9pt (generic text, list and menu fonts) as well as 12pt (window and title fonts): > Deja Vu 7pt: Regular, Bold, Italics > Deja Vu 9pt: Regular, Bold, Italics > Deja Vu 12pt: Regular, Bold, Italics > > Russian Language Support > ------------------------ > To input text in Russian language, install a font supporting the Cyrillic alphabet, then switch the locale accordingly: > > TTFileDescription installFamilyNamed: 'Arial'. > Locale switchToID: (LocaleID isoLanguage: 'ru'). > > This will enable Russian text input, display and processing. > > Improved Truetype Support > ------------------------- > The new TTFileDescription works just like TTFontDescription but operates on the files directly on disk. This helps greatly to support the m17n efforts since we no longer load all the fonts into memory. To use the available fonts on your platform, select some text, hit Cmd-k (Alt-k) and select "More (non-portable) fonts". > > Full Closure Support > -------------------- > This is a closure converted image. With full closure support, you can finally use recursive blocks like here: > > fac := [:n| n > 1 ifTrue:[n * (fac value: n-1)] ifFalse:[1]]. > fac value: 5. > > and close over temps correctly, such as here: > > (1 to: 10) do:[:i| WorldState addDeferredUIMessage:[Transcript cr; show: i]]. > > A new Development Model > ----------------------- > This image is being developed using a new development model described at > > http://board.squeak.org/2009/07/02/a-new-community-development-model/ > > The image itself started as Squeak3.10.2-7179-basic.image.

[Pharo-project] MPEG in Pharo depricated why?
by Torsten Bergmann Nov. 30, 2009

Nov. 30, 2009

>it requires FFI in the image, did we decide FFI and Alien should be in Pharo? >I think that is an open question. FFI not in the core - but maybe in the dev-image. Alien is AFAIK still not avaible for all major platforms >(b) I couldn't find any WIndow's users to help test it. Perhaps they don't exist? I use pharo/squeak on windows but I'm not a sophie user. There are other "pharo on windows" users too ... so just post and I'm sure you will find someone who is able to try out things. Even if windows may not be the typical dev platform for most of us it is still the largest consumer platform for commercial apps.

[Pharo-project] ocompletion usability
by Tudor Girba Nov. 30, 2009

Nov. 30, 2009

Hi, OCompletion certainly improved the coding experience in Pharo. But, I have a couple of usability suggestions with OCompletion to make it better. It would be great if someone (Romain? :)) could act on them: 1. Right now, OCompletion is triggered both by Tab and by Enter. It should be only Tab. Here is the reason. When I have a cascade, I want to have the methods starting from the next line, like this: browser mondrian title: 'Something'; painting: [:view ... ] So, after I type browser mondrian, I naturally want to press Enter. However, there exists a method called mondrianAnnounce:, and when I press Enter it gets filled in. So, the intent of Enter should be similar to that of Space: just as a whitespace. Tab is a good choice for triggering the completion because we basically only use Tabs only in a new line where the completion does not apply. 2. When no completion is offered and I press tab, I do get some list. Why is this not offered by default? Is it because it is slower? Is it because it is the regular ECompletion and that is not useful? 3. The completion is triggered only when typing, but not when removing characters. I believe it would be better if it followed me all the time. 4. When I want to navigate through the offered list using the down arrow the look changes and the items become wider. In fact, the same appears when I force completion by pressing Tab, so this leads me to believe that the change in the look is given by the change from O to E completion. The look should remain the same. Cheers, Doru -- www.tudorgirba.com "If you interrupt the barber while he is cutting your hair, you will end up with a messy haircut."

[Pharo-project] Where to put removed stuff?
by Simon Denier Nov. 30, 2009

Nov. 30, 2009

Hi there I think this has been discussed before, but I cant tell if there is an official rule for that (maybe it could be added to the wiki). So let's say I have a patch which removes the Collection arithmetic protocols (332). Now this protocol is still quite nice and we can offer it as an extension package for those who need it. Where should I put this Collection-Arithmetic package? In its own squeaksource project? Or is there a project for extra packages for Pharo? -- Simon

[Pharo-project] pharo and db support
by Tudor Girba Nov. 30, 2009

Nov. 30, 2009

Hi, I would like to collect a list of the solutions to link Pharo with existing databases. I am interested in both relational and in object databases. Is there a list somewhere? If not and if you know/use/develop/ such a solution, it would be great if we could put it together by collecting some data about these: - Pharo project and version - Supported database vendor and version - Maturity: prototype/production ready/ - Projects that use this one - Current development status and maintenance support (if any) - Website - Others Cheers, Doru -- www.tudorgirba.com "If you interrupt the barber while he is cutting your hair, you will end up with a messy haircut."

[Pharo-project] Method versioning in Pharo images
by csrabak＠bol.com.br Nov. 30, 2009

Nov. 30, 2009

I would like to know if the past history of the method's versions has been lost by design or accident. In the core image for example it is possible only for the method Object>>at: an entry "yo 6/29/2004 11:39". Are we considering the implementation of Pharo as a clean slate and we'll start from some epoch date? -- Cesar Rabak

Re: [Pharo-project] Continuous Integration Server for Pharo?
by Tim Mackinnon Nov. 30, 2009

Nov. 30, 2009

> I am currently working with Diego Kogan on the Continuous Integration Server for pharo. While implementing this in Smalltalk is interesting - have you looked at just using Hudson out of the box? Its a pretty trivial install and would get something running quite quickly to bootstrap features that might be interesting later? I often worry that we don't study/use the competition first to understand all of the good features. For example Hudson/Cruise will monitor for hung builds for you - they also have excellent web dashboards that give you great stats on whats happening. Sure to do it properly you would need a Monticello plugin to detect changes (and that might be a good project) - however to get going its pretty easy to have a timed build that runs every hour. The detail is then to just focus on getting something that will run from the command line - load some script from a base image and then pull in the relavent metacello? lineup - and report all transcript errors to an external file for Hudson to pick up? The second artifact could then be to take the produced image and then run unit tests from it - and again report the results to a file for output. Finally Hudson does a great job of fanning out to multiple machines to run Web Browser tests (which typically can take a bit longer) to get results from those as well. It seems like its potentially easy to focus on the build tool and not the script that it needs to run to test all of the relevant details? Tim
