> Hi Folks,
> Cuis 4.0 is available at http://www.jvuletich.org/Cuis/Index.html .
> This is a very important release. It's been over 10 months since Cuis
> 3.3, but all this time means that there are a lot of big news now.
> The biggest one is the public release of the Styled Text Editor, by
> Bernhard Pieber. Bernhard will do the announcement of this project
> himself, all I want to say is that Styled Text Editor is the driving
> force behind most of the new stuff in this release. I also want to add
> that I'm delighted to be able to work with Bernhard on his project,
> and that I'm more than happy with the wonderful effect this is having
> on Cuis itself.
> Check http://www.jvuletich.org/Cuis/CuisReleaseNotes.html .
> So, the main new features of this release of Cuis are the required
> support for External Packages. This is a very lightweight
> implementation of Packages, based on PackageInfo, but not on
> Monticello. Versioning is done with GitHub. Take a look at
> http://www.jvuletich.org/Cuis/CodeManagementInCuis4.html and
> http://www.jvuletich.org/Cuis/CuisAndGitHub.html .
> Full list of features (from the release notes):
> -----------------------------------------------------
>      - Package Support. Cuis 4.0 has a package implementation based on
> PackageInfo. Can be used with a Git repository (like GitHub) for
> package versioning. More info at "CodeManagementInCuis4" and
> "CuisAndGitHub". This infrastructure and process is used for the
> StyledTextEditor project, developed by Bernhard Pieber and Software
> Generation.
>      - New handling of ChangeSets. The idea is to have only one "live"
> change set that automatically captures all changes done to the Cuis
> Core image. Changes to Packages go to separate ChangeSets.
>      - UCompletion. A new implementation of Autocompletion for
> Smalltalk code. Activates with ctrl-space. Usually gives the selector
> desired as the first option. Some features are:
>          = Sorts by last definition of selector (Methods recently
> saved go first),
>          = Sorts appropriately all selectors matching entered prefix
> (no hardcoded limits, like 40 selectors matching 2 letters).
>          = Restricts suggestions if receiver is Global, a Constant or
> a pseudo-variable.
>          = Doesn't have an "expanded mode". Always shows relevant suggestions.
>          = Not restricted to a set of previously selected packages.
> All the methods in the system are accounted for.
>          = Very fast, thanks to an optimized Trie implementation.
>          = Compact code. Relies on services by Trie (for storing and
> querying selectors) and Shout (for parsing incomplete methods).
>          = Helps make Shout faster, by providing super fast queries of
> selector prefixes.
>          = Can be used for other applications besides Smalltalk code.
> Currently used for an English glossary for StyledTextEditor.
>      - Trie. Cuis 4.- includes a very optimized implementation of a
> Trie. Tries are dictionaries where keys are Strings. Lookups are
> extremely fast. Search for entries matching a prefix are extremely
> fast (O(1) regardless of the size of the collection). Addition and
> removals are quite fast too. Used for UCompletion, holding 11,000
> selectors. Also used for an English spell checker (in the
> StyledTextEditor project) holding 166,000 words. In both cases use of
> memory is quite reasonable (3 and 5.4 bytes per character in average)
> and query speed is extremely fast.
>      - Multiple level undo / redo in all text and code editors.
>      - ClickNHalf+Drag to select words. TripleClick or
> DoubleClickNHalf+Drag to select paragraphs. Like most modern text
> editors and wordprocessors do.
>      - Multiple text selection (with control+mouse). Like most modern
> text editors and wordprocessors do.
>      - Lf. The newline character is no longer Character cr (ASCII code
> 13), but Character lf (ASCII code 10). This is the standard in Mac and
> Unix platforms, and the required convention for GitHub. All the code
> in the image has been converted.
>      - cmd-w closes window below mouse pointer. cmd-< y cmd-> cycle
> through windows.
>      - New "PostIt" like HoverHelp morphs.
>      - Simplification / Redesign: Scrolling in Morphic (TransformMorph
> gone, etc).
>      - Deep cleanup in Paragraph and paragraph display services in
> Canvas and DisplayScanner (now MorphicScanner).
>      - MouseClickState refactor, to ease new gestures
> (ClickNHalf+Drag, DoubleClickNHalf+Drag, TripleClick).
>      - Killed AbstractEvent hierarchy. Unified event subscribing,
> triggering and handling everywhere in Cuis.
>      - More TextMorph cleanup.
>      - Numeric enhancements done by nice and jmv, both on Squeak and Cuis.
>      - Many minor enhancements, cleanups and bugfixes.
>      - Updates to Squeak: Numerics, Network, and many others.
> I hope you enjoy this release of Cuis as much as Bernhard and I
> enjoyed working on it. As usual, comments, discussion, bug reports,
> kudos and donations are all
> welcome!
> Cheers,
> Juan Vuletich
