GN allows any file in +# the build to declare build flags. If you need a flag for a single component, +# you can just declare it in the corresponding BUILD.gn file. +# +# - If your feature is a single target, say //components/foo, you can put +# a declare_args() block in //components/foo/BUILD.gn and use it there. +# Nobody else in the build needs to see the flag. +# +# - Defines based on build variables should be implemented via the generated +# build flag header system. See //build/buildflag_header.gni. You can put +# the buildflag_header target in the same file as the build flag itself. You +# should almost never set "defines" directly. +# +# - If your flag toggles a target on and off or toggles between different +# versions of similar things, write a "group" target that forwards to the +# right target (or no target) depending on the value of the build flag. This +# group can be in the same BUILD.gn file as the build flag, and targets can +# depend unconditionally on the group rather than duplicating flag checks +# across many targets. +# +# - If a semi-random set of build files REALLY needs to know about a define and +# the above pattern for isolating the build logic in a forwarding group +# doesn't work, you can put the argument in a .gni file. This should be put +# in the lowest level of the build that knows about this feature (which should +# almost always be outside of the //build directory!). +# +# Other flag advice: +# +# - Use boolean values when possible. If you need a default value that expands +# to some complex thing in the default case (like the location of the +# compiler which would be computed by a script), use a default value of -1 or +# the empty string. Outside of the declare_args block, conditionally expand +# the default value as necessary. +# +# - Use a name like "use_foo" or "is_foo" (whatever is more appropriate for +# your feature) rather than just "foo". +# +# - Write good comments directly above the declaration with no blank line. +# These comments will appear as documentation in "gn args --list". +# +# - Don't call exec_script inside declare_args.

Note +that access to the root SSL certificates is not needed if ContextProvider is +used to launch the `Context`. The `fuchsia.device.NameProvider` dependency comes +from fdio. + +#### present_view_capabilities.test-cmx +Services that are needed to render web content in a Scenic view and present it. +Most services are required per the FIDL documentation. +`fuchsia.ui.policy.Presenter` is additionally required by tests that create +views. + +#### vulkan_capabilities.test-cmx +Corresponds to the `VULKAN` flag. Required for enabling GPU-accelerated +rendering of the web content. + +#### web_engine_required_capabilities.test-cmx +Contains services that need to be present when creating a +`fuchsia.web.Context`. Note that the `fuchsia.scheduler.ProfileProvider` service +is only used in tests that encounter memory pressure code. + +#### web_instance_host_capabilities.test-cmx +Contains services that need to be present to use `WebInstanceHost`.
