This package can be used to build extensions for the Airship CMS.

It works as a command line program that can access a site with the Airship CMS installed and can generate several types of extension for this CMS after the user replies to several questions to configure the type of extension that you want to build.

Currently it can build Cabins, which self-contained applications, Gadgets which can alter the functionality of an existing Cabin or the Airship Engine itself, or Motifs that can alters the appearance of an existing Cabin.

The barge command can assembles a .phar or .zip of your extension that can be manually installed these into Airship.

Airship is a CMS system built with great security practices in mind since its design.

It can be extended in several ways with plugins defined by other developers, such as self-contained applications, gadgets which can alter those self-contained applications or the Airship Engine itself, or the the appearance of the pages generated by the CMS.

The package provides a command that makes it easier to start developing Airship extensions just by answering a few questions.

Barge

A command line interface for developing and distributing Airship cabins, gadgets, and motifs.

How to Install Barge

First, checkout our Git repository.

git checkout https://github.com/paragonie/airship-barge.git

Next, make sure you can execute the barge command.

cd airship-barge
chmod u+x barge

Make sure you install the dependencies via Composer. This will get Halite and our constant-time encoding library installed (both are libraries that barge uses extensively):

composer update

Finally, you'll want to create a symlink in /usr/bin so you can run barge commands by simply typing barge commandgoeshere:

ln -s ./barge /usr/bin/barge

How to Use Barge

Recommended: Create a workspace directory.

cd ~
mkdir barge-workspace
cd barge-workspace

If you don't already have a Supplier account, register one here.

Now you're ready to run your first barge command.

barge login

If this is your first time logging in, you'll need to run barge key twice. (Before the final version, we intend to make this process a lot smoother.)

barge key
# Follow the prompts to generate your master keypair
barge key
# Follow the prompts to generate your signing keypair, which you'll need to sign with your master key

Once your keypairs are generated, their public counterparts are uploaded to the server and synchronized to the entire network in an append-only data structure.

Once your keys are set up, you can begin to build CMS Airship extensions. What do you want to build?

  • A full application that can stand alone from Hull or Bridge: run `airship cabin`
  • A backend modification to an existing cabin: run `airship gadget`
  • A frontend modification to an existing cabin: run `airship motif`

After you follow the prompts, you should have a skeletal project directory waiting to be fleshed out.

Ready to deploy your first version? Okay, first:

barge build

This assembles a .phar or .zip of your extension. You can manually install these into a local Airship to test them out (recommended).

If you're ready to release it, first sign it with your signing key:

barge sign

And then release it:

barge release

If you've followed these steps, your package should be available for install in CMS Airship. If you release an update in this manner, it should be deployed and installed on all of your users' machines automatically (typically within an hour, unless they changed their configuration).
