#
# This Vagrantfile is designed to instantiate an Evernym Development Environment
# using Virtualbox as the vagrant provider and automates the following:
#
#  1. Clone all the required source code from github, or use clones you have
#     already created.
#    1.1. Source code should reside on the Virtualbox host (your desktop
#         environment) and be available in the Virtualbox guest as a "shared
#         folder". This allows the developer the option of using an IDE in their
#         own graphical desktop environment with their own license.
#    1.2. If you have not already cloned source, this Vagrant file assumes that
#         you have already forked the project and will prompt you for a username
#         and clone from "https://github.com/<username>/<project>.git" where
#         <username> is your username, and <project> is the target repo(s).
#  2. Install build tools/dependencies.
#  3. (Optional) Build source code on 'vagrant up'. Defaults to (N)o.
#  4. (Optional) Run unit tests on 'vagrant up'. Defaults to (N)o.
#
# //Prerequisites://
#  1. Install VirtualBox
#       - Note that Vagrant 2.0.0 doesn't seem to work with Virtualbox 5.2.
#         If you are using Vagrant <= 2.0.0, please use Virtualbox 5.1.30
#  2. Install Vagrant
#       - See Note under Install Virtualbox above
#  3. Install Git
#  4. Set the 'branch' for each of the development_repos below.
#     TODO: Display all branches, designate which branch the repo is on, and
#           allow the user to select a different branch. The following git
#           command should be helpful.
#           git branch --list --format "%(refname:short) %(HEAD)" | sort -u
#
# //How to use://
# Run 'vagrant up' and answer any questions this Vagrantfile or the Vagrant VM
# instance (i.e. network bridge) needs to complete the process. If you run into
# problems (i.e. shared folders, etc.), try 'vagrant reload --provision'. Doing
# so will restart the VM and re-run the provisioning script. A slightly more
# expensive operation would be to 'vagrant destroy' followed by 'vagrant up'.
#
# //Some details to be aware of://
#  1. All files and folders in the Vagrant project folder show up as shared
#     resources in /vagrant on all Vagrant VM(s)/guests instantiated by this
#     Vagrantfile. This is a design descision made by the Vagrant folks.
#  2. Source code will be cloned into this Vagrant project folder using the git
#     project name and then shared in /src/<git project name> in the Vagrant
#     guest VM(s). The .gitignore file in this Vagrant project folder ignores
#     these folders.
#  3. If you have your own source code clones, a symbolic link is
#     created in this Vagrant project folder. Doing so simplifies some discovery
#     logic in this Vagrantfile (ruby script). A side-effect of symlinking in
#     this Vagrant project folder is that the symlink is broken inside the
#     Virtualbox VM(s)/guests. Please do not remove or try to fix broken symlinks
#     in /vagrant in the Virtualbox VM(s)/guests. And be assured that the source
#     code associated with the symlinks on your Vagrant host are available in
#     /src/<git project name> in your Vagrant VM(s)/guests.

# //Make sure to be using the vagrant-vbguest plugin.//

# Code should reside on the Vagrant host and be mounted to the Vagrant VM
# using Vagrant's Shared Folder feature. Doing so allows a developer to use
# their favorite IDE/tools to write code and have a cheap, fast way to build
# and test their changes.

# //Define development repos and setup default Shared Folder path.//
#
# If you do not want to develop one or more of the following repos, you can
# "Skip" the repo when prompted.
#
# TODO: Decide how to chain dependendencies. For example, AWS Lambda code deps
#       indy-sdk. Perhaps this is where a providing both .deb and .rpm will help
#       if a dependency isn't being cloned and built from source, then a bundled
#       .deb or .rpm will be installed to provide the dependency?

# //- Pseudocode -//
# For each 'repo' in development_repos
#   Detect 'repo' in Vagrant project directory root
#     If 'repo' detected
#       Use the default directory path when defining synced folder
#     Else
#       Prompt the user for one of three options:
#         Option 1: Skip - I will not be developing 'repo'
#           Go to next repo
#         Option 2: Enter path of 'repo' git clone on Vagrant host
#           Update the <path> for 'repo' => <path> in the development_repos
#           associative array
#         Option 3: Clone 'repo' for me. Note that this option requires that you
#                   to have a fork of the 'repo' codebase on github/gitlab. The
#                   clone will be created in the root of this Vagrant project.
#                   - This option displays the repo URL and prompts the user for
#                     their github userid and builds the 'repo' URL.
#                   - The active branch will be the branch defined in the
#                     development_repos hash above.
#           Clone the repo
#             If failed to clone (404, etc.)
#               Exit with a verbose error message
