Replace flatbuffers with json serialization library #222

Closed coder137 closed 1 year ago

coder137 commented 1 year ago

https://github.com/nlohmann/json

Why?

Has easier serialization APIs for C++ STL storage
Can add custom types (C++ structs -> json)
Can output in human readable (json) and binary format (ubjson, cbor, messagepack etc)

Problems with Flatbuffers

Harder to create a C++ to FBS interface
For JSON like output need to use flexbuffers instead of flatbuffers (no array like root_type allowed)
Schema -> C++ conversion is harder, since there is no explicit support for hashmaps/hashtables/maps/tables.

TODO

[x] Add nlohmann::json library as a submodule
[x] Migrate custom_generator.fbs
[x] Custom Generator Unit tests
[x] Migrate target.fbs
[x] Target Unit tests
[x] Migrate FileGenerator and TemplateGenerator from flexbuffer to json
[x] Remove flatbuffers dependency and delete third_party flatbuffers submodule
[x] Update documentation for flatbuffers -> json migration
