Vagrant Unison Plugin

This is a Vagrant 1.1+ plugin that syncs files over SSH from a local folder to your Vagrant VM (local or on AWS). Under the covers it uses Unison

NOTE: This plugin requires Vagrant 1.1+,

Features

• Unisoned folder support via unison over ssh -> will work with any vagrant provider, eg Virtualbox or AWS.

Usage

1. You must already have Unison installed and in your path.
   • On Mac you can install this with Homebrew: brew install unison (on Yosemite you will have to use https://rudix-mountainlion.googlecode.com/files/unison-2.40.102-0.pkg)
   • On Unix (Ubuntu) install using sudo apt-get install unison
   • On Windows, download 2.40.102, unzip, rename Unison-2.40.102 Text.exe to unison.exe and copy to somewhere in your path.
2. Install using standard Vagrant 1.1+ plugin installation methods.

$ vagrant plugin install vagrant-unison

1. After installing, edit your Vagrantfile and add a configuration directive similar to the below:

Vagrant.configure("2") do |config|
  config.vm.box = "dummy"

  config.sync.host_folder = "src/"  #relative to the folder your Vagrantfile is in
  config.sync.guest_folder = "src/" #relative to the vagrant home folder -> /home/vagrant
  config.sync.ignore = "Name {.idea,.DS_Store}"

end

1. Start up your starting your vagrant box as normal (eg: vagrant up)

Start syncing Folders

Run vagrant sync to start watching the local_folder for changes, and syncing these to your vagrang VM.

Under the covers this uses your system installation of Unison, which must be installed in your path.

Start syncing Folders in repeat mode

Run vagrant sync-repeat to start in bidirect monitor (repeat) mode.

Start syncing Folders in interactive mode

Run vagrant sync-interact to start in interactive mode that allows solving conflicts.

Cleanup unison database

When you get

Fatal error: Warning: inconsistent state.  
The archive file is missing on some hosts.
For safety, the remaining copies should be deleted.
  Archive arb126d8de1ef26a835b94cf51975c530f on host blablabla.local should be DELETED
  Archive arbc6a36f85b3d1473c55565dd220acf68 on host blablabla is MISSING
Please delete archive files as appropriate and try again
or invoke Unison with -ignorearchives flag.

Run vagrant sync-cleanup to clear Archive from ~/Library/Application Support/Unison/ and files from host folder. Running Unison with -ignorearchives flag is a bad idea, since it will produce conflicts.

Development

To work on the vagrant-unison plugin, clone this repository out, and use Bundler to get the dependencies:

$ bundle

Once you have the dependencies, verify the unit tests pass with rake:

$ bundle exec rake

If those pass, you're ready to start developing the plugin. You can test the plugin without installing it into your Vagrant environment by just creating a Vagrantfile in the top level of this directory (it is gitignored) that uses it, and uses bundler to execute Vagrant:

$ bundle exec vagrant up 
$ bundle exec vagrant sync
