Caramel is a cross-platform module for building server applications in Swift.
Caramel is not production-ready, use at your own discretion. Discussion about design and architecture is welcome.
APIs like fread and NSFileManager were designed decades ago, around the design requirements of C-based languages. Approach API design by thinking about what is the most Swifty way to do things before taking inspiration from the past.
Although development and testing of the core framework may always be easier with Xcode on Macs, this is a cross-platform module, and we cannot become dependent on Apple's closed-source libraries. The only time it is okay to depend on Apple's frameworks is if it is an optimization on Apple's frameworks, as long as it is compliant with APIs working on non-Apple platforms.
Under the hood we may need to use POSIX APIs, or import the Darwin module, etc. These APIs often expose legacy data types, or rely on UnsafePointer types. All public APIs should absorb these legacy types into higher-order types, and unsafety should be absorbed by the framework. (A notable exception would be the Data class, which may expose an UnsafePointer for binary data, but other APIs should return Data types).
As much as possible, each type should not depend on other types in its base class. Instead, try to isolate interdependence into extensions. This keeps base types cleaner, easier to isolate, easier to test, and better encapsulated. But let the best API design win.
Xcode 7.1 can build the Caramel module for testing purposes. You'll need to build the libuv submdoule first.
git submodule update --init --recursivecd External/libuvsh autogen.sh./configuremakerm .libs/*.la* .libs/dylib(for some reason Xcode doesn't like these files)
Then build the Caramel scheme in Xcode, or duplicate the scheme to work on test projects. A more flexible testing harness is planned.
Caramel depends on the CUv module, which depends on libuv (v1.7.5 or higher). Follow the installation instructions to get libuv bootstrapped on your system, then swift build.
Include Caramel as a dependency by putting this in your Package.swift file:
import PackageDescription
let package = Package(
dependencies: [
.Package(url: "https://github.com/CaramelForSwift/Caramel.git", majorVersion: 0, minor: 1)
]
