Cappuccino is for building **applications** in the browser — especially complex, data-rich, line-of-business tools where productivity and user experience are paramount. Instead of direct manipulation of HTML, CSS, and the DOM, applications are built using Objective-J, a superset of JavaScript modeled on Objective-C.

Cappuccino is a comprehensive **framework** for building entire **applications**. It provides a fully integrated stack—including a mature UI library, event handling, and data management—designed for large-scale development. Beyond this, Cappuccino provides a more integrated and powerful data-binding layer inspired directly by Cocoa, which dramatically reduces boilerplate code for complex UIs as you can see in this [example code](https://github.com/daboe01/UIBuilder/tree/master/public/Frontend) that uses these features: @@ -103,19 +122,19 @@ Beyond this, Cappuccino provides a more integrated and powerful data-binding lay * **Advanced Filtering with Predicates:** A table displaying thousands of items can be filtered simply by setting a predicate (a declarative filter rule, e.g., `lastName BEGINSWITH 'S'`) on its controller. The UI updates instantly. This eliminates tons of manual state management and filtering logic code. * **Automatic Value Transformation:** Data can be easily formatted for display (e.g., dates, currency, booleans to "Yes/No") directly within the binding itself using value transformers, keeping model data pure and view logic minimal. -**Q: Can Cappuccino be used on Windows/Linux?** +**Q: Can Cappuccino be used on Windows/Linux?** **A:** Yes. The development tools run on Node.js and are platform-independent. Applications can be developed on any OS and deployed on any web server. -**Q: Is Xcode required?** +**Q: Is Xcode required?** **A:** No. Any code editor can be used. Xcode offers optional visual development tools for macOS users, but it is not a requirement. -**Q: Hasn't Apple moved on from Objective-C, making these APIs obsolete?** +**Q: Hasn't Apple moved on from Objective-C, making these APIs obsolete?** **A:** While Swift is Apple's newer language, Objective-C and AppKit remain foundational, actively supported technologies used in many of Apple's flagship applications. Cappuccino leverages the stability and power of this time-tested API design, which is independent of Apple's future product roadmap. -**Q: How can custom HTML, CSS, or JavaScript libraries be integrated?** +**Q: How can custom HTML, CSS, or JavaScript libraries be integrated?** **A:** Cappuccino abstracts away the DOM, but other web technologies can still be integrated. The `CPWebView` control allows arbitrary HTML/CSS/JS content to be embedded. Since Objective-J is a superset of JavaScript, JS libraries can be used and JS functions can be called directly from Objective-J code. -**Q: Does the LGPL license permit closed-source commercial applications?** +**Q: Does the LGPL license permit closed-source commercial applications?** **A:** Yes. The LGPLv2 license allows proprietary, closed-source applications to be built and distributed using Cappuccino. Sharing of source code is only required for any modifications made **to the Cappuccino framework itself**. The application code remains proprietary. --- diff --git a/Tests/Foundation/CPDictionaryTest.j b/Tests/Foundation/CPDictionaryTest.j index a94e05a38..299ee7685 100644 --- a/Tests/Foundation/CPDictionaryTest.j +++ b/Tests/Foundation/CPDictionaryTest.j @@ -490,8 +490,11 @@ var result = [CPMutableDictionary dictionary]; // Test basic for...of iteration - for (var [key, value] of dict) + for (var entry of dict) { + var key = entry[0], + value = entry[1]; + [result setObject:value forKey:key]; } @@ -514,6 +517,8 @@ var iterations = 0; for (var entry of emptyDict) { + // Explicitly evaluate the bound variable to satisfy the static analyzer. + [entry self]; iterations++; } [self assert:0 equals:iterations message:@"for...of on an empty dictionary should not iterate"]; diff --git a/Tests/Foundation/CPSetTest.j b/Tests/Foundation/CPSetTest.j index 414517361..7bd5ea760 100644 --- a/Tests/Foundation/CPSetTest.j +++ b/Tests/Foundation/CPSetTest.j @@ -428,10 +428,19 @@ // 3.
