package-syntax-parser

package-syntax-parser is a temporary substitute for the proposed frontend parser for the new @package syntax in Swift, based on SwiftSyntax. This package is a part of Google Summer of Code 2021 project SwiftPM support for Swift scripts.

NOTE: This tool is supposed to be deprecated once the corresponding frontend implementation is available.

Output

For test.swift:

@package(url: "https://github.com/apple/swift-log.git", from: "1.0.0")
import Logging

@package(path: "swift-argument-parser")
import ArgumentParser

struct Count: ParsableCommand {
    @Argument var inputFile: String
    @Argument var outputFile: String

    func run() throws {
        let logger = Logger(label: "com.example.Script.main")
        logger.info("""
            Counting words in '\(inputFile)' \
            and writing the result into '\(outputFile)'.
            """)

        // Read 'inputFile', count the words, and save to 'outputFile'.
    }
}
Count.main()

The output is:
