README
Introduction
Generate PHP protobuf code using PHP
./protoc-gen.php -o build tests/test3.proto
The generated message code is meant to work with Google protobuf's official PHP implementation: https://github.com/google/protobuf/tree/master/php
The generated service client code is meant to work with gRpc https://grpc.io/docs/quickstart/php.html#prerequisites
Requirements
- Unix/Linux system
- PHP >= 7.0 and composer installed
- Only support proto3 syntax proto file
- protoc installed, version >= 3.5
Usage
-
composer require liues1992/php-protobuf-generator
-
./vendor/bin/protoc-gen.php --out=build --grpc_out=build tests/*.proto
or use directly as plugin:protoc --php-custom_out=build --plugin=protoc-gen-php-custom=./vendor/bin/protoc-gen-plugin.php \ --grpc-php_out=build --plugin=protoc-gen-grpc-php=./vendor/bin/protoc-gen-grpc-plugin.php tests/*.proto
-
See the example folder for the generated code
Run test
composer test
TODO
- More test case
- Pack to phar
- Support proto2
- Custom generator support (write your own code generators by require this package)
Why do I need this instead of Google's default implementation?
- Sometimes you wish to customize the generated code,
which is complicated to do if you modify google/protobuf source code(c++) and recompile the protoc binary.
Think about above situations:
- Add convenience methods in message class..
- Support proto2
- Generate custom rpc code (if you are not using gRpc or you want it to use in PHP server side)
- Some bug in Google's generated code.
public function setEnum($var)
{
// GPBUtil::checkEnum accepts only on param
GPBUtil::checkEnum($var, \Gary\Test\Foo_Enum::class);
$this->enum = $var;
return $this;
}
- Cool to generate PHP code using PHP (easy for PHP developers to join).
How does it work
That's a secret. Find out yourself.
