# Targets Configuration
#  Middlemac is capable of building multiple targets for variants of your
#  application using the `middleman-targets` gem. Activate it and change
#  the option values here to suit your needs. Note that middleman-targets
#  adds configuration parameters to the base Middleman application; these
#  are *not* extension options.
##########################################################################
activate :MiddlemanTargets

# Set the default target, i.e, the target that is used automatically when you
# `middleman build` or `middleman server` without the `targets` CLI option.
config[:target] = :pro

# Targets

# NOTE: Ruby has a type of variable called a `symbol`, which are used below
# quite extensively and look like :this_symbol. Except they’re not really
# variables; you can’t assign values to them. Their value is themselves,
# though they have useful string representations (:this_symbol.to_s). You
# can even get the symbol representation of this_string.to_sym. Because
# they're unique, they make excellent array/hash keys and excellent,
# guaranteed unique values.

# :CFBundleID
# Just as different versions of your app must have different bundle identifiers
# so the OS can distinguish them, their help files must have unique bundle IDs,
# too. Your application specifies the help file `CFBundleID` in its
# `CFBundleHelpBookName` entry. Therefore for each target, ensure that your
# application has a `CFBundleHelpBookName` that matches the `CFBundleID` that
# you will set here.

# :HPDBookIconPath
# If specified a target-specific icon will be used as the help book icon by
# Apple’s help viewer. This path must be relative to the location of the
# `Resources` directory per Apple’s specification. If `nil` (or not present)
# then the default `SharedGlobalAssets/convention/icon_32x32@2x.png` will be
# used.

# :CFBundleName
# This value will be used for correct .plists and .strings setup, and will
# determine final .help directory name. All targets should use the same
# :CFBundleName. Built targets will be named `CFBundleName_(target).help`.
# This is *not* intended to be a product name, which is defined below.

# :ProductName
# You can specify different product names for each build target. The product
# name for the current target will be available via the `product_name` helper.

# :ProductVersion
# You can specify different product versions for each build target. The
# product version for the current target will be available via the
# `product_version` helper.

# :ProductURI
# You can specify different product URIs for each build target. The URI
# for the current target will be available via the `product_uri` helper.

# :ProductCopyright
# You should specify a copyright string to be included in the Apple Help Book.
# This typically appears when you print a Help Book.

# (other)
# You can specify additional .plist and .strings keys here, too. Have a look
# at `Info.plist.erb` and `InfoPlist.strings.erb`; simply use the exact key
# name and they will be supported. This is probably unneeded unless you are
# implementing advanced help book features.

# :Features
# A hash of features that a particular target supports or doesn't support.
# The `has_feature` function and several helpers will use the true/false value
# of these features in order to conditionally include content.
