Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

# This assumes that the host machine has r2 and all the reddit plugins checked
# out and in the correct directories--pay attention to both name and position
# relative to the r2 code:
#
# r2:         {ROOTDIR}/reddit
#
# plugins:
# i18n:       {ROOTDIR}/i18n
# about:      {ROOTDIR}/about
# meatspace:  {ROOTDIR}/meatspace
# liveupdate: {ROOTDIR}/liveupdate
# adzerk:     {ROOTDIR}/adzerk
# donate:     {ROOTDIR}/donate
# gold:       {ROOTDIR}/gold
#
# private internal reddit plugin:
# private:    {ROOTDIR}/private
#
# The plugins are all optional, but they will get cloned in the VM (and as a
# result be uneditable from the host) by the install script if their directory
# is missing but is included in `plugins` below. The general rule for naming
# each plugin directory is that "reddit-plugin-NAME" should be in the directory
# {ROOTDIR}/NAME.
#
# To start your vagrant box simply enter `vagrant up` from {ROOTDIR}/reddit.
# You can then ssh into it with `vagrant ssh`.
#
# avahi-daemon is installed on the guest VM so you can access your local install
# at https://reddit.local. If that fails you'll need to update your host
# machine's hosts file (/etc/hosts) to include the line:
# 192.168.56.111 reddit.local
#
# If you want to create additional vagrant boxes you can copy this file
# elsewhere, but be sure to update `code_share_host_path` to be the absolute
# path to {ROOTDIR}.
