Useful with targets outside //, e.g. in parent directories -# above "//". The default input root is // -# Example: Vivaldi's source root is "//vivaldi/", -# and "//vivaldi/chromium/" is "//" -# In such cases, not using this argument lead to the output files being -# located in different directories than expected. -# -# testonly (optional) -# -# visibility (optional) -# -# visibility_blink (optional) -# The value to use for visibility for the blink variant. If unset, -# |visibility| is used. -# -# cpp_only (optional) -# If set to true, only the C++ bindings targets will be generated. -# -# NOTE: If the global |enable_mojom_fuzzer| build arg is true, JS bindings -# will still be generated even when |cpp_only| is set to |true|, unless -# you also set |enable_fuzzing| to |false| in your mojom target. -# -# cpp_typemaps (optional) -# A list of typemaps to be applied to the generated C++ bindings for this -# mojom target. Note that this only applies to the non-Blink variant of -# generated C++ bindings. -# -# Every typemap is a GN scope describing how one or more mojom types maps -# to a non-mojom C++ type, including necessary deps and headers required -# for the mapping to work. See the Typemaps section below. -# -# blink_cpp_typemaps (optional) -# Same as above, but for the Blink variant of generated C++ bindings. -# -# cpp_proxy_target (optional) -# The name of a target which all C++ dependencies will link against -# instead of linking directly against this mojom target's generated C++ -# sources. Normally when declaring invoking the mojom("foo") target, GN -# emits a source_set or component target named "foo" which encompasses the -# default variant of generated C++ bindings. This changes that to instead -# emit a group("foo") which merely forwards public_deps to the named -# `cpp_proxy_target`. That target must in turn depend on -# "foo_cpp_sources". -# -# This is useful primarily in conjunction with export_define et al to -# embed generated C++ bindings within an existing component target. -# -# blink_cpp_proxy_target (optional) -# Same concept as `cpp_proxy_target` above, but affects the generated -# "foo_blink" Blink-variant C++ bindings. -# -# cpp_configs (optional) -# A list of extra configs to apply to the default variant of generated C++ -# bindings. -# -# blink_cpp_configs (optional) -# A list of extra configs to apply to the Blink variant of generated C++ -# bindings. -# -# mojom_source_deps (optional) -# A list of mojoms this target depends upon. This is equivalent to -# public_deps except that the C++ bindings depend on each of the named -# "foo" targets' "foo_cpp_sources" rather than on foo's -# `cpp_proxy_target`. It only makes sense to use this for dependencies -# that set `cpp_proxy_target`, and only when the dependent mojom() would -# otherwise have circular dependencies with that proxy target. -# -# mojom_blink_source_deps (optional) -# Same as above but depends on "foo_blink_cpp_sources" and is used for -# dependencies that specify a `blink_cpp_proxy_target`. -# -# generate_java (optional) -# If set to true, Java bindings are generated for Android builds. If -# |cpp_only| is set to true, it overrides this to prevent generation of -# Java bindings. -# -# enable_js_fuzzing (optional) -# Enables generation of javascript fuzzing sources for the target if the -# global build arg |enable_mojom_fuzzer| is also set to |true|. -# Defaults to |true|. If JS fuzzing generation is enabled for a target, -# the target will always generate JS bindings even if |cpp_only| is set to -# |true|. See note above. -# -# enable_mojolpm_fuzzing (optional) -# Enables generation of fuzzing sources for the target if the global build -# arg |enable_mojom_fuzzer| is also set to |true|. Defaults to |true|. -# -# support_lazy_serialization (optional) -# If set to |true|, generated C++ bindings will effectively prefer to -# transmit messages in an unserialized form when going between endpoints -# in the same process. This avoids the runtime cost of serialization, -# deserialization, and validation logic at the expensive of increased -# code size. Defaults to |false|. -# -# disable_variants (optional) -# If |true|, no variant sources will be generated for the target. Defaults -# to |false|. -# -# disallow_native_types (optional) -# If set to |true|, mojoms in this target may not apply the [Native] -# attribute to struct or enum declarations. This avoids emitting code -# which depends on legacy IPC serialization. Default is |false|, meaning -# [Native] types are allowed. -# -# disallow_interfaces (optional) -# If set to |true|, mojoms in this target may not define interfaces. -# Generates bindings with a smaller set of dependencies. Defaults to -# |false|. -# -# scramble_message_ids (optional) -# If set to |true| (the default), generated mojom interfaces will use -# scrambled ordinal identifiers in encoded messages. -# -# component_output_prefix (optional) -# The prefix to use for the output_name of any component library emitted -# for generated C++ bindings. If this is omitted, C++ bindings targets are -# emitted as source_sets instead. Because this controls the name of the -# output shared library binary in the root output directory, it must be -# unique across the entire build configuration. -# -# This is required if |component_macro_prefix| is specified. -# -# component_macro_prefix (optional) -# This specifies a macro prefix to use for component export macros and -# should therefore be globally unique in the project. For example if this -# is "FOO_BAR", then the generated C++ sources will be built with -# IS_FOO_BAR_{suffix}_IMPL defined, and the generated public headers will -# annotate public symbol definitions with -# COMPONENT_EXPORT(FOO_BAR_{suffix}). "suffix" in this case depends on -# which internal subtarget is generating the code (e.g. "SHARED", or a -# variant name like "BLINK"). -# -# enabled_features (optional) -# Definitions in a mojom file can be guarded by an EnableIf attribute. If -# the value specified by the attribute does not match any items in the -# list of enabled_features, the definition will be disabled, with no code -# emitted for it. -# -# generate_closure_exports (optional) -# Generates JS lite bindings will use goog.provide and goog.require -# annotations to export its symbols and import core Mojo bindings support -# and other mojom dependency modules. Use this if you plan to compile your -# bindings into a larger JS binary. Defaults to |false|, instead -# generating JS lite bindings which assume they will be manually loaded in -# correct dependency order. Note that this only has an effect if -# the |enable_mojom_closure_compile| global arg is set to |true| as well. -# -# generate_webui_js_bindings (optional) -# Generate WebUI bindings in JavaScript rather than TypeScript. Defaults -# to false. ChromeOS only parameter. -# -# generate_legacy_js_bindings (optional) -# Generate js_data_deps target containing legacy JavaScript bindings files -# for Blink tests and other non-WebUI users when generating TypeScript -# bindings for WebUI. Ignored if generate_webui_js_bindings is set to -# true. -# -# js_generate_struct_deserializers (optional) -# Generates JS deerialize methods for structs. -# -# extra_cpp_template_paths (optional) -# List of extra C++ templates that are used to generate additional source -# and/or header files. The templates should end with extension ".tmpl". -# -# webui_module_path (optional) -# The path or URL at which modules generated by this target will be -# accessible to WebUI pages. This may either be an absolute path or -# a full URL path starting with "chrome://resources/mojo". If this path -# is not specified, WebUI bindings will not be generated. -# -# If an absolute path, a WebUI page may only import these modules if -# they are added to that page's data source (usually by adding the -# modules to the mojo_files list for build_webui(), or by listing the -# files as inputs to the page's ts_library() and/or generate_grd() build -# steps. -# -# If this is is instead a URL string starting with -# "chrome://resources/mojo", the resulting bindings files should -# be added to one of the lists in ui/webui/resources/mojo/BUILD.gn, -# at which point they will be made available to all WebUI pages at the -# given URL. -# -# Note: WebUI module bindings are generated in TypeScript by default, -# unless |generate_webui_js_bindings| is specified as true. -# -# The following parameters are used to support the component build. They are -# needed so that bindings which are linked with a component can use the same -# export settings for classes. The first three are for the chromium variant, and -# the last three are for the blink variant. These parameters can also override -# |component_macro_prefix| for a specific variant, allowing e.g. one variant -# to be linked into a larger non-mojom component target, while all other -# variants get their own unique component target. -# export_class_attribute (optional) -# The attribute to add to the class declaration. e.g. "CONTENT_EXPORT" -# export_define (optional) -# A define to be added to the source_set which is needed by the export -# header. e.g. "CONTENT_IMPLEMENTATION=1" -# export_header (optional) -# A header to be added to the generated bindings to support the component -# build. e.g. "content/common/content_export.h" -# export_class_attribute_blink (optional) -# export_define_blink (optional) -# export_header_blink (optional) -# These three parameters are the blink variants of the previous 3. -# -# The following parameters are used to correct component build dependencies. -# They are needed so mojom-mojom dependencies follow the rule that dependencies -# on a source set in another component are replaced by a dependency on the -# containing component. The first two are for the chromium variant; the other -# two are for the blink variant. -# overridden_deps (optional) -# The list of mojom deps to be overridden. -# component_deps (optional) -# The list of component deps to add to replace overridden_deps. -# overridden_deps_blink (optional) -# component_deps_blink (optional) -# These two parameters are the blink variants of the previous two. -# -# check_includes_blink (optional) -# Overrides the check_includes variable for the blink variant. -# If check_includes_blink is not defined, the check_includes variable -# retains its original value. -# -# Typemaps -# ======== -# The cpp_typemaps and blink_cpp_typemaps each specify an optional list of -# typemapping configurations. Each configuration is a GN scope with metadata -# describing what and how to map. -# -# Typemap scope parameters: -# types -# A list of type specifications for this typemap. Each type specification -# is a nested GN scope which can be expressed with the following syntax: -# -# { -# mojom = "foo.mojom.Bar" -# cpp = "::foo::LegitBar" -# move_only = true -# # etc... -# } -# -# Each type specification supports the following values: -# -# mojom (required) -# The fully qualified name of a mojom type to be mapped. This is a -# string like "foo.mojom.Bar". -# -# cpp (required) -# The fully qualified name of the C++ type to which the mojom type -# should be mapped in generated bindings. This is a string like -# "::base::Value" or "std::vector<::base::Value>". -# -# copyable_pass_by_value (optional) -# A boolean value (default false) which effectively indicates -# whether the C++ type is very cheap to copy. If so, generated -# bindings will pass by value but not use std::move() at call sites. -# -# default_constructible (optional) -# A boolean value (default true) which indicates whether the C++ -# type is default constructible. If a C++ type is not default -# constructible (e.g. the implementor of the type prefers not to -# publicly expose a default constructor that creates an object in an -# invalid state), Mojo will instead construct C++ type with an -# argument of the type `mojo::DefaultConstruct::Tag` (essentially a -# passkey-like type specifically for this use case). -# -# force_serialize (optional) -# A boolean value (default false) which disables lazy serialization -# of the typemapped type if lazy serialization is enabled for the -# mojom target applying this typemap. -# -# forward_declaration (optional) -# A forward declaration of the C++ type, which bindings that don't -# need the full type definition can use to reduce the size of -# the generated code. This is a string like -# "namespace base { class Value; }". -# -# hashable (optional) -# A boolean value (default false) indicating whether the C++ type is -# hashable. Set to true if true AND needed (i.e. you need to use the -# type as the key of a mojom map). -# -# move_only (optional) -# A boolean value (default false) which indicates whether the C++ -# type is move-only. If true, generated bindings will pass the type -# by value and use std::move() at call sites. -# -# nullable_is_same_type (optional) -# A boolean value (default false) which indicates that the C++ type -# has some baked-in semantic notion of a "null" state. If true, the -# traits for the type must define IsNull and SetToNull methods. -# -# When false, nullable fields are represented by wrapping the C++ -# type with absl::optional, and null values are simply -# absl::nullopt. -# -# Additional typemap scope parameters: -# -# traits_headers (optional) -# Headers which must be included in the generated mojom in order for -# serialization to be possible. This generally means including at least -# the header for the corresponding mojom traits definitions. -# -# traits_private_headers (optional) -# Headers which must be included in generated C++ serialization code for -# a mojom using the typemap. This should be used only when including a -# header in |traits_headers| is problematic for compilation, as is -# sometimes the case with legacy IPC message headers. -# -# traits_sources (optional) -# The references to the source files (typically a single .cc and .h file) -# defining an appropriate set of EnumTraits or StructTraits, etc for the -# the type-mapping. Using this will cause the listed sources to be -# integrated directly into the dependent mojom's generated type-mapping -# targets. -# -# Prefer using |traits_public_deps| over inlined |traits_sources|, as this -# will generally lead to easier build maintenance over time. -# -# NOTE: If a typemap is shared by Blink and non-Blink bindings, you cannot -# use this and MUST use |traits_public_deps| to reference traits built -# within a separate target. -# -# traits_deps / traits_public_deps (optional) -# Any dependencies of sources in |traits_headers| or |traits_sources| must -# be listed here. -# -template("mojom") { - assert( - defined(invoker.sources) || defined(invoker.deps) || - defined(invoker.public_deps), - "\"sources\" or \"deps\" must be defined for the $target_name template.") - - if (defined(invoker.export_class_attribute) || - defined(invoker.export_define) || defined(invoker.export_header)) { - assert(defined(invoker.export_class_attribute)) - assert(defined(invoker.export_define) || defined(invoker.cpp_configs)) - assert(defined(invoker.export_header)) - } - if (defined(invoker.export_class_attribute_blink) || - defined(invoker.export_define_blink) || - defined(invoker.export_header_blink)) { - assert(defined(invoker.export_class_attribute_blink)) - assert(defined(invoker.export_define_blink) || - defined(invoker.blink_cpp_configs)) - assert(defined(invoker.export_header_blink)) - - # Not all platforms use the Blink variant, so make sure GN doesn't complain - # about these values being inconsequential. - not_needed(invoker, - [ - "export_class_attribute_blink", - "export_define_blink", - "export_header_blink", - ]) - } - if (defined(invoker.overridden_deps) || defined(invoker.component_deps)) { - assert(defined(invoker.overridden_deps)) - assert(defined(invoker.component_deps)) - } - - if (defined(invoker.overridden_deps_blink) || - defined(invoker.component_deps_blink)) { - assert(defined(invoker.overridden_deps_blink)) - assert(defined(invoker.component_deps_blink)) - } - - # Type-mapping may be disabled or we may not generate C++ bindings. - not_needed(invoker, - [ - "cpp_typemaps", - "blink_cpp_typemaps", - ]) - - require_full_cpp_deps = - !defined(invoker.disallow_native_types) || - !invoker.disallow_native_types || !defined(invoker.disallow_interfaces) || - !invoker.disallow_interfaces - - all_deps = [] - mojom_cpp_deps = [] - if (defined(invoker.deps)) { - all_deps += invoker.deps - mojom_cpp_deps += invoker.deps - } - if (defined(invoker.public_deps)) { - all_deps += invoker.public_deps - mojom_cpp_deps += invoker.public_deps - } - if (defined(invoker.mojom_source_deps)) { - all_deps += invoker.mojom_source_deps - } - if (defined(invoker.mojom_blink_source_deps)) { - all_deps += invoker.mojom_blink_source_deps - } - not_needed([ "mojom_deps" ]) - - if (defined(invoker.component_macro_prefix)) { - assert(defined(invoker.component_output_prefix)) - } - - group("${target_name}__is_mojom") { - } - - # Explicitly ensure that all dependencies (invoker.deps and - # invoker.public_deps) are mojom targets. - group("${target_name}__check_deps_are_all_mojom") { - deps = [] - foreach(d, all_deps) { - name = get_label_info(d, "label_no_toolchain") - toolchain = get_label_info(d, "toolchain") - deps += [ "${name}__is_mojom(${toolchain})" ] - } - } - - sources_list = [] - if (defined(invoker.sources)) { - sources_list = invoker.sources - } - - # Listed sources may be relative to the current target dir, or they may be - # absolute paths, including paths to generated mojom files.
