# Template to package a shared library into a Mac framework bundle.
#
# By default, the bundle target this template generates does not link the
# resulting framework into anything that depends on it. If a dependency wants
# a link-time (as well as build-time) dependency on the framework bundle,
# depend against "$target_name+link". If only the build-time dependency is
# required (e.g., for copying into another bundle), then use "$target_name".
#
# Arguments
#
# framework_version:
# string, version of the framework. Typically this is a
# single letter, like "A".
#
# framework_contents:
# list of string, top-level items in the framework. This is
# the list of symlinks to create in the .framework directory that link
# into Versions/Current/.
#
# info_plist:
# (optional) string, path to the Info.plist file that will be used for
# the bundle.
#
# info_plist_target:
# (optional) string, if the info_plist is generated from an action,
# rather than a regular source file, specify the target name in lieu
# of info_plist. The two arguments are mutually exclusive.
#
# output_name:
# (optional) string, name of the generated framework without the
# .framework suffix. If omitted, defaults to target_name.
#
# extra_substitutions:
# (optional) string array, 'key=value' pairs for extra fields which are
# specified in a source Info.plist template.
#
# This template provides three targets for the resulting framework bundle. The
# link-time behavior varies depending on which of the two targets below is
# added as a dependency:
# - $target_name only adds a build-time dependency. Targets that depend on
# it will not link against the framework.
# - $target_name+link adds a build-time and link-time dependency. Targets
# that depend on it will link against the framework.
# - $target_name+link_nested adds a build-time and link-time dependency, but
# only on the shared library and not the fully-assembled framework bundle.
# This should only be used for other nested binary components of the
# framework bundle (e.g. Helpers) that themselves depend on the main shared
# library of the framework bundle.
#
# The build-time-only dependency is used for when a target needs to use the
# framework either only for resources, or because the target loads it at run-
# time, via dlopen() or NSBundle. The link-time dependency will cause the
# dependee to have the framework loaded by dyld at launch.
#
# Example of build-time only dependency:
#
# mac_framework_bundle("CoreTeleportation") {
# sources = [ ... ]
# }
#
# bundle_data("core_teleportation_bundle_data") {
# deps = [ ":CoreTeleportation" ]
# sources = [ "$root_out_dir/CoreTeleportation.framework" ]
# outputs = [ "{{bundle_contents_dir}}/Frameworks/{{source_file_part}}" ]
# }
#
# app_bundle("GoatTeleporter") {
# sources = [ ... ]
# deps = [
# ":core_teleportation_bundle_data",
# ]
# }
#
# The GoatTeleporter.app will not directly link against
# CoreTeleportation.framework, but it will be included in the bundle's
# Frameworks directory.
#
# Example of link-time dependency:
#
# mac_framework_bundle("CoreTeleportation") {
# sources = [ ... ]
# ldflags = [
# "-install_name",
# "@executable_path/../Frameworks/$target_name.framework"
# ]
# }
#
# bundle_data("core_teleportation_bundle_data") {
# deps = [ ":CoreTeleportation+link" ]
# sources = [ "$root_out_dir/CoreTeleportation.framework" ]
# outputs = [ "{{bundle_contents_dir}}/Frameworks/{{source_file_part}}" ]
# }
#
# app_bundle("GoatTeleporter") {
# sources = [ ... ]
# deps = [
# ":core_teleportation_bundle_data",
# ]
# }
#
# Note that the framework is still copied to the app's bundle, but dyld will
# load this library when the app is launched because it uses the "+link"
# target as a dependency. This also requires that the framework set its
# install_name so that dyld can locate it.
#
# See "gn help shared_library" for more information on arguments supported
# by shared library target.
