Get path to Swift script from within script

Question

I\'m writing a script in Swift, and I want it to modify some files that always exist in the same directory as the script itself. Is there a way to get the path to the script fro

Answer 1

The accepted answer doesn't work in Swift 3. Also, this is a more straightforward approach:

import Foundation

let currentDirectoryURL = URL(fileURLWithPath: FileManager.default.currentDirectoryPath)
let url = URL(fileURLWithPath: CommandLine.arguments[1], relativeTo: currentDirectoryURL)
print("script at: " + url.path)

However, it has the same problem pointed out by @rob-napier, if the script's directory is in your PATH.

Answer 2

just in swift:

let cwd = FileManager.default.currentDirectoryPath
print("script run from:\n" + cwd)

let script = CommandLine.arguments[0];
print("\n\nfilepath given to script:\n" + script)

//get script working dir
if script.hasPrefix("/") { //absolute
    let path = (script as NSString).deletingLastPathComponent
    print("\n\nscript at:\n" + path)
} else {
    let urlCwd = URL(fileURLWithPath: cwd)
    if let path = URL(string: script, relativeTo: urlCwd)?.path {
        let path = (path as NSString).deletingLastPathComponent
        print("\n\nscript at:\n" + path)
    }
}
