Mentioned in Awesome Vapor Built with Swift 4.2

What is it?

Ether is a CLI the integrates with SPM (Swift Package Manager), similar to NPM's command-line tool.

How do I install it?

With Homebrew:

brew tap Ether-CLI/tap
brew install ether

If you don't have, want, or can't use Homebrew, you can run the following script to install Ether:

curl https://raw.githubusercontent.com/calebkleveter/Ether/master/install.sh | bash

What features does it have?

Installs a package with its dependencies:

ether install <name>

Example output:

Installing Dependency [Done]
📦  10 packages installed


dependencies: [
    .package(url: "https://github.com/vapor/console.git", from: "3.0.0"),
    .package(url: "https://github.com/vapor/core.git", from: "3.0.0"),
    .package(url: "https://github.com/vapor/vapor.git", from: "3.0.0") <=== Added Package


The install command has a rather interesting method of getting the proper package. Because you can have packages with the same name by different authors, Ether will run a search based on the argument you pass in and get the most stared result. If the name contains a slash (/), then the URL will be created directly without a search like this:


Note that this is case insensitive.

Deliver the Packages to a Playground

Added a -p,--playground option to the install command to install dependencies to an Xcode Playground instead of an SPM project. Playground installs do not support packages the use C module maps.

Also added a -t,--targets flag to the install command, which specifies which targets the new dependency will be added to.

2018.08.11 - Aug 11, 2018

Testing, Testing, Testing...


  • new command no longer fails when cleaning new project's manifest.
  • Dependency writing when last dependency has a trailing comma.
  • White space when adding first dependency to manifest.


  • --print/-p flag to config command to output config values.
  • test command, for formatted output when running swift test.

Hang the Fetch!

Execution of certain commands would hang while fetching package data. That should be resolved now.

Auto-Committed Template Group List

The template command was broken out to multiple commands and placed in a command group:

ether template create <NAME>
ether template remove <NAME>
ether template list

There are also more configurations available. These ones are for auto commits after installing or uninstalling a package:

  • install-commit: The commit message to use on package install. Use &0 as package name placeholder.
  • remove-commit: The commit message to use on when a package is removed. Use &0 as package name placeholder.
  • signed-commits: If set to a truthy value (true, yes, y, 1), auto-commits will pass in the -S flag

If the commit messages are not set, Ether will not commit the changes.
