This directory is here to hold .gni files that contain sets of GN build
arguments for given configurations.
(Currently this directory is empty because we removed the only thing here, but
this has come up several times so I'm confident we'll need this again. If this
directory is still empty by 2017, feel free to delete it. --Brett)
Some projects or bots may have build configurations with specific combinations
of flags. Rather than making a new global flag for your specific project and
adding it all over the build to each arg it should affect, you can add a .gni
file here with the variables.
For example, for project foo you may put in build/args/foo.gni:
target_os = "android"
use_pulseaudio = false
use_ozone = true
system_libdir = "foo"
Users wanting to build this configuration would run:
$ gn args out/mybuild
And add the following line to their args for that build directory:
import("//build/args/foo.gni")
# You can set any other args here like normal.
is_component_build = false
This way everybody can agree on a set of flags for a project, and their builds
stay in sync as the flags in foo.gni are modified.

# Copyright 2015 The Chromium Authors. All rights reserved.
# Use of this source code is governed by a BSD-style license that can be

# Generates a header with preprocessor defines specified by the build file.
#
# The flags are converted to function-style defines with mangled names and
# code uses an accessor macro to access the values. This is to try to
# minimize bugs where code checks whether something is defined or not, and
# the proper header isn't included, meaning the answer will always be silently
# false or might vary across the code base.
#
# In the GN template, specify build flags in the template as a list
# of strings that encode key/value pairs like this:
#
# flags = [ "ENABLE_FOO=1", "ENABLE_BAR=$enable_bar" ]
#
# The GN values "true" and "false" will be mapped to 0 and 1 for boolean
# #if flags to be expressed naturally. This means you can't directly make a
# define that generates C++ value of true or false for use in code. If you
# REALLY need this, you can also use the string "(true)" and "(false)" to
# prevent the rewriting.
# To check the value of the flag in C code:
#
# #include "path/to/here/header_file.h"
#
# #if BUILDFLAG(ENABLE_FOO)
# ...
# #endif
#
# const char kSpamServerUrl[] = BUILDFLAG(SPAM_SERVER_URL);
#
# There will no #define called ENABLE_FOO so if you accidentally test for that
# in an ifdef it will always be negative.
#
#
# Template parameters
#
# flags [required, list of strings]
# Flag values as described above.
#
# header [required, string]
# File name for generated header. By default, this will go in the
# generated file directory for this target, and you would include it
# with:
# #include "<path_to_this_BUILD_file>/<header>"
#
# header_dir [optional, string]
# Override the default location of the generated header. The string will
# be treated as a subdirectory of the root_gen_dir. For example:
# header_dir = "foo/bar"
# Then you can include the header as:
# #include "foo/bar/baz.h"
#
# deps, public_deps, testonly, visibility
# Normal meaning.
#
#
# Grit defines
#
# If one .grd file uses a flag, just add to the grit target:
#
# defines = [
# "enable_doom_melon=$enable_doom_melon",
# ]
#
# If multiple .grd files use it, you'll want to put the defines in a .gni file
# so it can be shared. Generally this .gni file should include all grit defines
# for a given module (for some definition of "module"). Then do:
#
# defines = ui_grit_defines
#
# If you forget to do this, the flag will be implicitly false in the .grd file
# and those resources won't be compiled. You'll know because the resource
# #define won't be generated and any code that uses it won't compile. If you
# see a missing IDS_* string, this is probably the reason.
#
#
# Example
#
# buildflag_header("foo_features") {
# header = "foo_features.h"
#
# flags = [
# # This uses the GN build flag enable_doom_melon as the definition.
# "ENABLE_DOOM_MELON=$enable_doom_melon",
#
# # This force-enables the flag.
# "ENABLE_SPACE_LASER=true",
#
# # This will expand to the quoted C string when used in source code.
# "SPAM_SERVER_URL=\"http://www.example.com/\"",

# This file introduces two related templates that act like action and
# action_foreach but instead of running a Python script, it will compile a
# given tool in the host toolchain and run that (either once or over the list
# of inputs, depending on the variant).
#
# Parameters
#
# tool (required)
# [label] Label of the tool to run. This should be an executable, and
# this label should not include a toolchain (anything in parens). The
# host compile of this tool will be used.
#
# outputs (required)
# [list of files] Like the outputs of action (if using "compiled_action",
# this would be just the list of outputs), or action_foreach (if using
# "compiled_action_foreach", this would contain source expansions mapping
# input to output files).
#
# args (required)
# [list of strings] Same meaning as action/action_foreach.
#
# inputs (optional)
# Files the binary takes as input. The step will be re-run whenever any
# of these change. If inputs is empty, the step will run only when the
# binary itself changes.
#
# visibility
# deps
# args (all optional)
# Same meaning as action/action_foreach.
#
#
# Example of usage:
#
# compiled_action("run_my_tool") {
# tool = "//tools/something:mytool"
# outputs = [
# "$target_gen_dir/mysource.cc",
# "$target_gen_dir/mysource.h",
# ]
#
# # The tool takes this input.
# inputs = [ "my_input_file.idl" ]
#
# # In this case, the tool takes as arguments the input file and the output
# # build dir (both relative to the "cd" that the script will be run in)
# # and will produce the output files listed above.
# args = [
# rebase_path("my_input_file.idl", root_build_dir),
# "--output-dir", rebase_path(target_gen_dir, root_build_dir),
# ]
# }
#
# You would typically declare your tool like this:
# if (host_toolchain == current_toolchain) {
# executable("mytool") {
# ...
# }
# }
# The if statement around the executable is optional. That says "I only care
# about this target in the host toolchain". Usually this is what you want, and
# saves unnecessarily compiling your tool for the target platform. But if you
# need a target build of your tool as well, just leave off the if statement.

# WHAT IS THIS FILE?
# =============================================================================
#
# This is the master GN build configuration. This file is loaded after the
# build args (args.gn) for the build directory and after the toplevel ".gn"
# file (which points to this file as the build configuration).
#
# This file will be executed and the resulting context will be used to execute
# every other file in the build. So variables declared here (that don't start
# with an underscore) will be implicitly global.
# =============================================================================
# PLATFORM SELECTION
# =============================================================================
#
# There are two main things to set: "os" and "cpu". The "toolchain" is the name
# of the GN thing that encodes combinations of these things.
#
# Users typically only set the variables "target_os" and "target_cpu" in "gn
# args", the rest are set up by our build and internal to GN.
#
# There are three different types of each of these things: The "host"
# represents the computer doing the compile and never changes. The "target"
# represents the main thing we're trying to build. The "current" represents
# which configuration is currently being defined, which can be either the
# host, the target, or something completely different (like nacl). GN will
# run the same build file multiple times for the different required
# configuration in the same build.
#
# This gives the following variables:
# - host_os, host_cpu, host_toolchain
# - target_os, target_cpu, default_toolchain
# - current_os, current_cpu, current_toolchain.
#
# Note the default_toolchain isn't symmetrical (you would expect
# target_toolchain). This is because the "default" toolchain is a GN built-in
# concept, and "target" is something our build sets up that's symmetrical with
# its GYP counterpart. Potentially the built-in default_toolchain variable
# could be renamed in the future.
#
# When writing build files, to do something only for the host:
# if (current_toolchain == host_toolchain) { ...
if (target_os == "") {
target_os = host_os
}
if (target_cpu == "") {
if (target_os == "android") {
# If we're building for Android, we should assume that we want to
# build for ARM by default, not the host_cpu (which is likely x64).
# This allows us to not have to specify both target_os and target_cpu
# on the command line.
target_cpu = "arm"
} else {
target_cpu = host_cpu
}
}
if (current_cpu == "") {
current_cpu = target_cpu
}
if (current_os == "") {

# =============================================================================
# BUILD FLAGS
# =============================================================================
#
# This block lists input arguments to the build, along with their default
# values.
#
# If a value is specified on the command line, it will overwrite the defaults
# given in a declare_args block, otherwise the default will be used.
#
# YOU SHOULD ALMOST NEVER NEED TO ADD FLAGS TO THIS FILE. 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. This will execute the script
# even if the value is overridden, which is wasteful. See first bullet.
