NSGetEnviron and PR#400

yageek · June 10, 2016, 9:19am

Hello,

I initiated the PR #400 in the package manager and I’m trying to implement
the last suggestion in this thread.

This is to recopy the current environment variables for git clone instead
of cherry-pick several specifics one.

I would like to use the _NSGetEnviron variable that should be defined in
Darwin but I don’t manage to reference it.

I tried:

return environ

return Darwin.environ

return libc.environ

I’m using the DEVELOPMENT-SNAPSHOT-2016-05-09-a toolchain.

Any tips on how to call this method from Swift ?

Regards

Yannick

Hi,

There is no native method in swift to get the environment list right now
but you can use Foundation's NSProcessInfo
If you want an example:

github.com

apple/swift-package-manager/blob/main/Sources/Commands/SwiftTestTool.swift#L188


      
              case `default`
          
              /// Capture XCTest events and provide a summary.
              case experimentalSummary
          
              /// Let the test process emit parseable output to the console.
              case experimentalParseable
          }
          
          /// swift-test tool namespace
          public struct SwiftTestTool: SwiftCommand {
              public static var configuration = CommandConfiguration(
                  commandName: "test",
                  _superCommandName: "swift",
                  abstract: "Build and run tests",
                  discussion: "SEE ALSO: swift build, swift run, swift package",
                  version: SwiftVersion.current.completeDisplayString,
                  subcommands: [
                      List.self, Last.self
                  ],
                  helpNames: [.short, .long, .customLong("help", withSingleDash: true)])

Thanks
