#   Requirements
#      apache2
#      postfix
#
#   Instructions
#   1º Set up your enviroment configs;
#      workspace=/home/user/workspace
#
#   2º Add your user on apache's group
#
#   3º Skip this step
#
#   4º Use this script
#
# --------------------------------------------------------------------------- #

# Workspace directory
workspace=/path/to/your/workspace

# Developer's user
user=developer

# Apache's group (make sure your user belongs to apache's group)
group=www-data

# How to use:
#   ./webhost.sh website.local

# What webhost.sh do:
#   First, the directory $workspace/website will be created if it doesn't exists, and its permission will be set
#   Then will be append a new line on /etc/hosts with the virtual host's name
#   After a virtual host will be created on apache (note that the apache virtual hosts configuration only allow localhost access)
#   And finally a virtual mail will created

# --------------------------------------------------------------------------- #

# First param must to be the virtual server's name
servername=$1

# Virtual server path
serverpath=$workspace/${servername/.local/} #remove .local

# Check privileges
[ `id -u` -ne 0 ] && {
	echo -e "Super user required. \nTry again using 'sudo $0'." >&2
	exit 1
}

# Check param
[ -z "$servername" ] && {
	echo -e "The virtualhost's name must be given. \nExample: $0 '$HOSTNAME.local'" >&2
	exit 2
}
# Check usage: ask for suffix to prevent accidental use
[ -n "`grep " " <<< $servername`" ] && {
	echo -e "Hostname cannot contain space characters. \nExample: $0 '$HOSTNAME.local'" >&2
	exit 3
}
# Check usage: ask for suffix to prevent accidental use
[ -z "`grep "\.local" <<< $servername`" ] && {
	echo -e "Suffix '.local' must be given. \nExample: $0 '$HOSTNAME.local'" >&2
	exit 3
}
# Check if serverpath isn't a file 
[ -f $serverpath ] && {
	echo -e "$servername isn't a good name because there's a file '$serverpath'.\nTry another hostname." >&2
	exit 4
}

# Confirm operation
read -p "A virtualhost will be created for '$servername'.
Do you confirm the operation? [yes/no]: " confirm

# If serverpath doesn't exists, make it

# Set up the permissions

# Update hosts file, if it's needed.

	echo "File /etc/hosts updated."
