Re: [squeak-dev] [Ann] Cuis 4.0 is released!

Hi Hannes,

Quoting "H. Hirzel" hannes.hirzel@gmail.com:

Hello again

I realized that instead of

Character cr there is Character newLineCharacter

and instead of

Transcript show: 'abc'; cr.

there is

Transcript show: 'abc'; newLine.

Yes. Cuis 4 uses LF line separator. Having the #cr selector is now ambiguous. Should it mean 'cr' (ascii 13) or 'newLine' (whatever the convention is)? I removed #cr so senders will be aware of this, and be explicit on what they want (usually #newLine).

Here my question: What do the paragraph signs with the boxes around them mean? (see screen shot)

--Hannes

It means that that code use cr (Ascii 13) as the newLine character. This is the convention used by Smalltalk-80, Squeak, Pharo and older versions of Cuis.

An easy way to fix it is to do 'select all' (cmd-a), 'fix newLine' (cmd-shift-u) and 'accept' or 'save' (cmd-s). You can do this in the browser, or on changeset files in the File List.

Looks nice indeed. The rewrite of TextEditor looks quite impressive. I tested a bit but Cuis has a quite limited font selection ;-) How do I import more fonts to Cuis ?

A couple of bugs:

Found that when a menu is pinned down its sub-menus disappear quite fast. Try to pin down New Morph menu and access sub-menus for example.

Also

There is a MNU when you select WorldMenu/Windows/Move Windows Onscreen and a Transcript is open.

Cheers, Karl

Hi Folks,

Cuis 4.0 is available at http://www.jvuletich.org/Cuis/**Index.htmlhttp://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.htmlhttp://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.htmlhttp://www.jvuletich.org/Cuis/CodeManagementInCuis4.htmland http://www.jvuletich.org/Cuis/**CuisAndGitHub.htmlhttp://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
