Hello all,
Now that the `package` subcommand has been implemented (see https://github.com/apple/swift-evolution/blob/master/proposals/0085-package-manager-command-name.md\), some of the options have ended up with awkward syntax. For example, the old `--init` option took an optional package type parameter, and after the command renaming, the syntax has become somewhat awkward: `package init=library`.
In order to clean this up, we have added some flags for the newly introduced subcommands, and I wanted to run them by the list to get any feedback before making the change.
The command line interface vended by the new `package` subcommand introduced by SE-0085 is shown in its help text:
OVERVIEW: Perform operations on Swift packages
USAGE: swift package [command] [options]
COMMANDS:
init [--type <type>] Initialize a new package (executable|library)
fetch Fetch package dependencies
update Update package dependencies
generate-xcodeproj [--output <path>] Generates an Xcode project
show-dependencies [--format <format>] Print dependency graph (text|dot|json)
dump-package [--output <path>] Print Package.swift as JSON
OPTIONS:
--chdir <path> Change working directory before any command [-C]
--color <mode> Specify color mode (auto|always|never)
--verbose Increase verbosity of informational output [-v]
-Xcc <flag> Pass flag through to all C compiler instantiations
-Xlinker <flag> Pass flag through to all linker instantiations
-Xswiftc <flag> Pass flag through to all Swift compiler instantiations
NOTE: Use `swift build` to build packages, and `swift test` to test packages
The changes are to introduce new flags for the parameters that were previously passed to the subcommand names themselves. The last three flags listed (-Xcc, -Xlinker, and -Xswiftc) are unchanged to maintain compatibility with the swift compiler — this will likely be revisited at a later time.
As described in SE-0085, the `build` subcommand stays. It how has this interface:
OVERVIEW: Build sources into binary products
USAGE: swift build [mode] [options]
MODES:
--configuration <value> Build with configuration (debug|release)
--clean [<mode>] Delete artifacts (build|dist)
OPTIONS:
--chdir <path> Change working directory before any other operation [-C]
--build-path <path> Specify build directory
--color <mode> Specify color mode (auto|always|never)
--verbose Increase verbosity of informational output [-v]
-Xcc <flag> Pass flag through to all C compiler instantiations
-Xlinker <flag> Pass flag through to all linker instantiations
-Xswiftc <flag> Pass flag through to all Swift compiler instantiations
NOTE: Use `swift package` to perform other functions on packages
Finally, the `test` subcommand remains largely unmodified, with this interface:
OVERVIEW: Build and run tests
USAGE: swift test [specifier] [options]
SPECIFIER:
-s TestModule.TestCase Run a test case subclass
-s TestModule.TestCase/test1 Run a specific test method
OPTIONS:
--chdir Change working directory before any other operation [-C]
--build-path <path> Specify build directory
NOTE: Use `swift package` to perform other functions on packages
