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. Project itself has been split > into Project / MVCProject / MorphicProject such that Project itself is > abstract and various requests are handled properly in the subclasses. > > Collections > ----------- > Several improvements have been added to Collections. Sets have become faster, > Arrays now print in brace form by default, Dictionary>>keys return an array > instead of a set. > > Monticello > ---------- > Various load-order issues have been fixed within Monticello, making loading > of packages more robust. Monticello and PackageInfo have been sped up in > several areas making browsing of large repositories significantly faster. > > Faster UTF-8 Conversions > ------------------------ > Generalize trick from ByteString>>#squeakToUtf8 to every converter using > class instance variables. Dramatically improves performance of file > operations. > > FaceLift > -------- > An adaptation of Newspeak's Facelift look has been added to Squeak under the > code name of "Botox" (meaning a small set of carefully chosen injections to > improve the out of the box look for Squeak). > > Shout > ----- > Shout (Syntax Hightlighting As You Type) has been added to this image. As > with all new additions, it can be easily unloaded for people wanting smaller > images. > > ToolBuilder conversion > ---------------------- > All the tools have been given a make-over, removing pretty much all of the > interface construction code and replacing it by ToolBuilder specs. 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.
