multiplatform artifacts.
2019-06-21
-
New: Experimental multiplatform runtime.
Starting with this version,
wire-runtime
is published as a multiplatform Kotlin artifact. While the JVM artifact is binary- and behavior-compatible with 3.0.0-alpha01, artifacts for other platforms may not work correctly at this point. The artifact name for the JVM artifact has been changed towire-runtime-jvm
: now, in order to depend on the multiplatform runtime, use the following Gradle dependency declaration:api "com.squareup.wire:wire-runtime:3.0.0-alpha02"
and if you want to depend on the JVM artifact only, use the following declaration:
api "com.squareup.wire:wire-runtime-jvm:3.0.0-alpha02"

New: Kotlin Generator
Wire 3 can generate Kotlin data classes. To enable this feature via the command line API, pass in the
--kotlin_out
parameter that should specify the output directory for the generated*.kt
files.Given the following simple proto:
message Person { required string name = 1; required int32 id = 2; optional string email = 3; }
the generated Kotlin code will look like the following:
data class Person( @field:WireField(tag = 1, adapter = "com.squareup.wire.ProtoAdapter#STRING") val name: String, @field:WireField(tag = 2, adapter = "com.squareup.wire.ProtoAdapter#INT32") val id: Int, @field:WireField(tag = 3, adapter = "com.squareup.wire.ProtoAdapter#STRING") val email: String? = null, val unknownFields: ByteString = ByteString.EMPTY ) : Message<Person, Person.Builder>(ADAPTER, unknownFields) { companion object { @JvmField val ADAPTER: ProtoAdapter<Person> = ... // code omitted for brevity
The
copy()
method of a data class replaces most usages of the builder. If your code relies on theBuilder
, you can enable fullBuilder
generation by passing the--java_interop
parameter to the compiler. -
New: gRPC support
In addition to generating Kotlin code from proto messages, Wire can now generate code for gRPC endpoints. Here's an example schema:
service RouteGuide { // A simple RPC. // // Obtains the feature at a given position. // // A feature with an empty name is returned if there's no feature at the given // position. rpc GetFeature(Point) returns (Feature) {} }
The generated code will look like the following (message protos, referenced by the schema, are omitted):
interface RouteGuide : Service { @WireRpc( path = "/routeguide.RouteGuide/GetFeature", requestAdapter = "routeguide.Point#ADAPTER", responseAdapter = "routeguide.Feature#ADAPTER" ) suspend fun GetFeature(request: Point): Feature }
All four gRPC modes are supported: the generated code uses suspendable functions to implement non-blocking asynchronous execution. In streaming modes,
ReceiveChannel
andSendChannel
are used to listen to asynchronous data in a non-blocking fashion.This feature works out of the box in Wire 3 compiler as long as the input file contains a gRPC schema.
-
New: Gradle plugin
Here's an example Gradle configuration:
apply plugin: 'com.squareup.wire' wire { // Keeps only 'Dinosaur#name' as the root of the object graph roots 'squareup.dinosaurs.Dinosaur#name' // Keeps all fields, except 'name', in 'Dinosaur' prunes 'squareup.dinosaurs.Dinosaur#name' // Both roots and prunes in an external file rules 'rules.txt' kotlin { javaInterop true out "${buildDir}/generated/custom" } }
The
wire
extension introduces the concept of compilation targets, such askotlin
andjava
, where each target has its own configuration properties. Multiple targets can be supplied, which benefits use cases such as migrating Java protos to Kotlin. -
New: Decouple the option of using Android annotations for nullability from the option of having messages implement Parcelable.
-
New: Wire Moshi adapter for serializing proto JSON representation using the Moshi library.
-
New: Implement support for custom enum types.

ProtoFile
to its schema. -

-
New: Allow custom types to be constrained with a 'with' clause.
-
New: Generate a constructor which takes in a
Message.Builder
instead of all fields separately. -
New: Add location to the error message about unsupported group elements.
-
New: Permit single files to be used on the proto path.
-
Fix: Emit '=' for syntax declaration.
-
Fix: Don't crash when a comment has a dollar sign.
-
Fix: Return subclass type instead of abstract parameterized type for newBuilder.
-
Fix: Validate enum namespace in file context are unique.
2016-06-17
- New: Support for
map
type in the schema, compiler, and runtime! - New:
AndroidMessage
base class consolidates everything required for supporting Android and will now be used for generating code with--android
. - New:
stream
keyword in RPC definitions is now parsed and exposed in the schema. - Fix: Nested types which are retained no longer cause their enclosing type to be retained. Instead, non-instantiable empty types will be generated for pruned enclosing types.
- Fix: Remove per-type
Parcelable.Creator
classes and instead use a single type which delegates to the message'sProtoAdapter
. - Fix: Retain information on redacted fields even when options were pruned.
- Fix: Do not generate code for handling
null
from list types (and now map types) which are guaranteed to never benull
.
2016-04-15
- Fix: Gson type adapter now deserializes JSON null literals to empty list for repeated fields.
2016-02-01
- New:
reserved
keyword is now supported and enforced. - Fix: Defer reflection-based lookup of enum method until first use to avoid class loading race conditions.
- Fix: Support single-quoted string literals.
- Fix: Adjacent string literals are not correctly concatenated.
2016-01-18
- Empty lists of packed values were being encoded incorrectly. In Wire 2.0.x our message
adapters incorrectly included empty lists for
[packed=true]
rather than omitting them. This is now fixed. - New:
Message.encode()
to concisely encode a message. - New:
MessageAdapter.decode(ByteString)
to decode a message from a byte string without an intermediate byte array. - New: Wire now includes a sample code generation for service interfaces.
2016-01-04
- New:
ProtoAdapter.get
overload which returns an adapter given an instance of a message. - New:
@Nullable
annotations are emitted foroptional
fields when using--android
. - Fix: Remove the need for
javac
to generate synthetic accessor methods in the generated code. This results in smaller code size and less method references (for Android users).
2015-12-14
- Fix: Exclude unknown fields when encoding JSON and drop unknown fields when parsing JSON.
- Fix: Ensure JSON encoding and decoding works in the default generation mode (not just
--compact
) by always adding@WireField
metadata to message fields. - Fix: Update to JavaPoet 1.4 for more accurate generation of valid Java code.
2015-11-12
- Fix: Do not emit
case
statements for aliased enum constant values. The first constant for a value will be returned when deserializing. - Fix: Emit
@Deprecated
annotation on deprecated enum constants. - Fix: Correctly prune dependencies of excluded message, enum, or service members. Previously the dependencies of an excluded member were retained despite the member itself being omitted.

Wire 2 is a backwards-incompatible release. It makes breaking changes to the compiler, runtime, extensions, and generated code. These changes aren’t made lightly as we’ve endured the upgrade in our own projects! We believe the cost of migration is worth the benefits.
We’ve created the wire-schema
library that models .proto
schema definitions. This is a
capable library that packs several neat features. You can load a Schema
from .proto
files
located on the local file system, a ZIP or JAR file, or any java.nio.FileSystem
like
Jimfs. You can prune this schema with includes or excludes, allowing you to reuse .proto
definitions with minimal code. And you can decode data directly from a schema: no code generation
is necessary!
We’ve flattened extensions. Wire 2.0 combines the fields defined directly on messages with fields defined far away in extensions. In the generated code, extension fields look just like every other field! One limitation of this approach is that it’s no longer possible to compile extensions separately from the messages they extend. For this reason we now recommend always generating all Wire code in a single step.
We’ve rearranged the runtime. Types related to the protocol buffers format are now prefixed
Proto
and types related to our implementation are prefixed Wire
. To encode and decode messages
you must first get an adapter either from the ADAPTER
constant or from ProtoAdapter.get()
. You
no longer need a Wire
instance!
- New
ADAPTER
constant on most messages gives access to encode & decode values. This replaces the encoding and decoding methods onWire
. - Guard against null lists. Code that passes
null
to builder methods expecting aList
used to accept that; now Wire throws aNullPointerException
. Similarly list elements must also be non-null. - New
Message.newBuilder()
API. This replaces the previous copy constructor onBuilder
. - New:
Message.withoutUnknownFields()
strips unknown fields. - Fix: Always throw
ProtocolException
when there are decoding problems. - Fix: Stricter checking for oneof fields. Previously it was possible to create instances with multiple values set!
- Fix: Improve redacting of repeated fields.
- Fix:
ProtoReader
now silently unpacks packed values. - Fix:
ProtoReader
doesn’t return groups to callers.
- The Java generator is now standalone. Use these APIs programmatically to build plugins without delegating to the command line interface.
- New: Prune schemas using includes and excludes. The
IdentifierSet
can be used to configure which types and members are retained and which are pruned. - New: Encode and decode values directly from the schema.
- New: Improved error messages for validation.
- Fix: Strict imports.
- Fix: Detect and forbid conflicts on extension tags.
- New: Always use Wire’s bundled
descriptor.proto
. Previously to define custom options you needed to import a potentially-inconsistent descriptor. - New: Emit all types when no
.proto
files are explicitly specified. - New: Generate code for encoding and decoding messages. The previous, reflection-based
encoder and decoder are accessible with
--compact
. - New:
ServiceFactory
has been removed. To generate code for your services, load a schema withwire-schema
and then use a library like JavaPoet to generate your own code. TheJavaGenerator
class can be used to look up Java names of message types. - New: Compiler will load all
.proto
files if none are explicitly specified. - New: Load
.proto
files from ZIP and JAR files. - New: The
--android
flag causes Wire messages to implementParcelable
. - New: Support multiple
--proto_path
arguments - New: The
--named_files_only
flag limits which.proto
files yield.java
files. This was the default in Wire 1.x. - New: The
--no_options
flag has been deleted. Use--excludes=google.protobuf.*
instead.
- Extensions have been flattened.
- Fix: Better field resolution for options.
- Fix: Extension fields must not be
required
.
2015-06-27
- New:
oneof
support! - Fix: Correct serialization of repeated unknown fields.
- Fix: Removed superfluous
private
modifier on enum constructor. - Warning: The 'protoparser' library was updated to version 4.0. This changes the type passed to
any
ServiceWriter
implementations.
2015-03-05
- New: Messages implement
Serializable
. The serialized form follows protobuf encoding, so renaming fields is safe as long as tags are consistent. (Renaming classes is unsafe, however). Note that extension fields are deserialized as unknown fields.
2015-01-16
- New:
--quiet
and--dry-run
command-line arguments. - Fix: Handle an extension registry with zero or only one item.
- Okio dependency bumped to 1.2.0.

- Fix: Correctly throw
IOException
when parsing bad input fails. - Fix: Ensure emitted code references to
Arrays.asList
correctly compiles in some edge cases. - 'UNDEFINED' enum value has been removed.
2014-09-15
- New: 'UNDEFINED' enum value represents values that the generated code is unable to handle.
- New: Service writer implementation can now be specified on the command-line.
2014-06-18
- New: Generate interface definition for a
Service
with a partial list of methods. - Okio dependency bumped to 1.0.0.
2014-04-22
- New: Options on enums and enum values are now supported.
- New: Options ending with
.redacted
on fields will omit values fromtoString
. - New:
Redactor
creates copies of messages with redacted fields omitted. - Various internal serialization improvements and memory reduction.
- Okio dependency bumped to 0.9.0.
2014-04-22
-
Replace Wire's ByteString class with the one from Okio (https://github.com/square/okio). This is a breaking API change.
-
Add a new static method
Wire.parseFrom(okio.Source input, Class<M> messageClass)
. -
Reimplement Wire's input handling to use Okio internally.
-
Provide basic support for generating code from service declarations (see README.md).
-
Improve deserialization performance.
-
Fix a bug where no some extension dependencies were not detected.
2014-03-28
- New: Support service declarations as roots. The request and response types of their methods will be included.
2014-03-27
- Fix: Enum value duplicate check now correctly looks at names instead of values.
2014-03-25
- New: Automatically add Maven plugin's generated source as a compilation root.

- New: Emit field options. Use
--no_options
flag to disable. - New:
@Deprecated
is now added to fields and setters on the builder. - New: Maven plugin for running the compiler as part of a build.
- Fix: Treat empty and null repeated fields the same in
equals()
andhashCode()
.
Note: This version is not backwards compatible with code generated from previous versions.
2013-11-01
- New:
--registry_class
compiler argument emits a class with a list of extensions suitable for passing to theWire
constructor. - Fix: Ensure all trailing whitespace is trimmed on documentation.
2013-10-23
- Fix: Correct parsing and emission of multi-line documentation.
2013-10-22
- New: Support for message options.
- New: Check for duplicate field tag numbers.
- New: Emit Javadoc on messages, enum values, and builder methods.
- Fix: Emit imports for extension fields and classes outside of package.
- Fix: Correctly generate sources for protos with the same basename.
- Fix: Do not generate default constants for message types.
- Fix: Avoid shadowing fields named "result", "other", or "o".
2013-08-27
- New: Support reading directly from
InputStream
. - New: Add '
other == this
' shortcut in generatedequals()
methods.
2013-08-23
Initial version.
