cuis's Introduction

Cuis

Cuis is a free Smalltalk-80 environment originally derived from [Squeak] (http://www.squeak.org) with a specific set of goals: being simple and powerful. It is also portable to any platform, fast and efficient. This means it is a great tool for running on any hardware, ranging from supercomputers to tablets and smart phones, and everything in between, including regular PCs.

Cuis is

Simple
Small
Clean

Like Squeak, Pharo and other Squeak variants, Cuis is also:

Open Source
Multiplatform

Like other Smalltalk-80 environments (including Squeak, Pharo and others), Cuis is also:

A complete development environment written in itself
A pure Object Oriented language

Cuis is different from other Squeak variants in that it takes an active attitude towards system complexity.

As systems grow older, they usually become more complex. New features are added as layers on top of whatever is below, sometimes without really understanding it, and almost always without modifying it. Complexity grows without control. At some point, the system can't evolve anymore and becomes "legacy code".

The only way to avoid this is by understanding the complete system, and reengineering the whole system all the time. Keeping it simple and consistent.

This is important. Complexity puts a limit to the level of understanding of the system a person might reach, and therefore limits the things that can be done with it. Dan Ingalls says all this in "Design Principles Behind Smalltalk". Even if you have already done so, please go and read it again!

Cuis is continuously evolving towards simplicity. Each release is better (i.e. simpler) than the previous one. At the same time, features are enhanced, and any bugs fixed. Cuis includes recent enhancements from Squeak, but only those that meet Cuis objectives: stuff whose complexity outweighs its utility is not included.

Please check the Release Notes and Code Management in Cuis 4, about developing packages for Cuis, and Using Git and GitHub to host and manage Cuis code.

cuis's Issues

Cancelling package creation does not work

Steps to reproduce:

Open > Installed Packages
Click Create Package
Click Cancel
Note that a package without a name is shown in Installed Packages

Separate shout colors for messages and message arguments

Right now messages and message arguments use the same shout color. It would be nice to be able to use different colors and also be able to turn off italics for arguments

Change Sorter and SUnit don't observe paneBackgroundFrom in their list view

[REQ] FillInTheBlankMorphClass>>requestPassword:

Requesting a method that echos back *'s instead of the characters being typed for password fields.

ImageMorph class comment

Under the code examples in the class comment . "(Form fromFileNamed: 'myGraphicsFileName') asMorph openInWorld" doesn't work (no asMorph method in Form).

Potential change?
ImageMorph new image: (Form fromFileNamed: 'myGraphicsFileName'); openInWorld.

IndentingListMorph>>unhighlight sets text to black

When browsing directories in File List, the tree view pane changes the text color to black after unselecting a directory. When using dark pane background, the text becomes unreadable on deselection. It looks like IndentingListMorph>>unhighlight is the origin of this setting.

Possible solution?

IndentingListItemMorph>>unhighlight

complexContents highlightingColor ifNotNil: [self color: Theme current text].
self redrawNeeded

"save as" dialog box does not observe Theme>>paneBackgroundFrom:

"save as" dialog observes the Theme>>text attribute but not the Theme>>paneBackgroundFrom:. This results in unreadable text in themes which invert the text/background colors.

Cut-and-paste with the & symbol results in truncated text

Example: type 'a & b' in a workspace. Attempts to cut or copy the text and then paste, will result in only 'a ' being pasted.

UI refresh bug in Cuis4.1-1663 image

When I open the latest image in Cog.r2714.app on my Mac and move one window over another I get refresh bugs. See:

installMonticelloPackage: missing

I cannot find the method to install a Monticello package anymore.

"Message Names" doesn't observe Theme>>useUniformColors

"Message Names" retains it's green coloring even when Theme>>useUniformColors is set to true

disable button label embossing

It would be nice to have the ability to disable embossed text in button labels

[REQ] Add SocketStream>>crlf or SocketStream>>crlfString method

Adding a crlf to an ascii network stream is a frequent operation. I hesitate to add anything to Cuis, but I've been typing 'nextPutAll: String crlfString' a lot lately.

CuisV4.sources location

On my Mac I usually keep CuisV4.sources besides my VM, e.g. Cog.r2714.app. I keep my image and changes pair in different folders, add an alias to the VM and start Cuis by dragging the image on to the VM alias. This is nice because I need only one copy of the sources file.

This works fine with images from Cuis4WithLatestUpdates up to Cuis4.1-1576.image. Any image from Cuis4.1-1617 freezes the VM without showing a window.
