ObjectBox Generator

Current version: 4.0.0-beta

ObjectBox is a superfast cross-platform object-oriented database. ObjectBox Generator produces code for ObjectBox C, C++ and Go APIs (more languages to be supported in the future). This greatly simplifies using ObjectBox in your favourite language.

Download

Install the objectbox-generator by downloading the latest binary for your OS from releases. If you want, add it to $PATH for convenience.

Alternatively, CMake users can fetch ObjectBox and the Generator for C++ using FetchContent (link).

Build

If you prefer to build the generator yourself (vs. downloading), clone this repo and simply run make. This will produce an "objectbox-generator" binary in the main project directory.

Build notes:

  • To build yourself, you need Go, Make, CMake and a C++11 tool chain.
  • To run test suite, run make test-depend test.
  • test-depend needs to run only once to download objectbox core library and to build flatcc.
  • A full test cycle can be triggered by make clean all test-depend test.

Getting started

To get started, have a look at the specific language bindings (the approaches differ):

  • C and C++ repository and docs. In summary, you define a FlatBuffers schema file, and the ObjectBox Generator will create plain C++ data classes and helper classes that "glue" the data classes to the ObjectBox runtime library. CMake users can also use the convenient add_obx_schema() task instead of using the generator executable directly.
  • Go repository and docs. Here, you start with Go data structs, for which the Generator generates the glue code directly.

Development Notes

  • Clean test cache: go clean -testcache
  • Run test suite test/comparison with flag -update to update expected files.
  • Run test suite test/integration with flag -insource to generate code in source may be helpful (e.g. cd test/integration && go test ./... -insource)
