LocalizableDSL

Implementation of Localizables.string to Swift enum conversion

How to Build

LocalizableDSL framework depends on:

• SwiftSyntax (https://github.com/apple/swift-syntax)
• SwiftFormat (https://github.com/apple/swift-format)
• lib_InternalSwiftSyntaxParser.dylib

Setup Dependencies

SwiftSyntax

1. git clone -b swift-5.2-branch https://github.com/apple/swift-syntax
2. cd swift-syntax
3. swift package generate-xcodeproj
4. drag & drop generated SwiftSyntax.xcodeproj to LocalizableDSL project navigator as a dependency (replacing existing missing one)

SwiftFormat

1. git clone -b swift-5.2-branch https://github.com/apple/swift-format
2. cd swift-format
3. swift package generate-xcodeproj
4. drag & drop generated swift-format.xcodeproj to LocalizableDSL project navigator as a dependency (replacing existing missing one)

lib_InternalSwiftSyntaxParser.dylib

To quote from https://github.com/apple/swift-syntax:

Embedding SwiftSyntax in an Application

SwiftSyntax depends on the lib_InternalSwiftSyntaxParser.dylib/.so library which provides a C interface to the underlying Swift C++ parser. When you do swift build SwiftSyntax links and uses the library included in the Swift toolchain. If you are building an application make sure to embed _InternalSwiftSyntaxParser as part of your application's libraries.

So, in order to add lib_InternalSwiftSyntaxParser.dylib as a dependency, search in Finder for "lib_InternalSwiftSyntaxParser.dylib" and drag & drop (or better copy) found dylib into LocalizableDSL directory, then, drag & drop lib_InternalSwiftSyntaxParser.dylib into LocalizableDSL project navigator (replacing existing missing one)

Examples

LocalizableDSL provides public API:

public class DSL {
    public init()
    public func parse(input: String) throws -> String
}

Usage

let parser = DSL()
let output = try parser.parse(input: "\"MyClass.textLabel.text\" = \"hello there\";")
print(output)
// prints
enum L {
  enum MyClass {
    enum TextLabel {
      static let text = NSLocalizedString("MyClass.textLabel.text", comment: "")
    }
  }
}
