ark-fbs 0.1.2

FlatBuffers schema parsing + JSON<->binary helpers (pybind11)

Ark FBS

This is a standalone PyPI package that provides a thin pybind11 wrapper around flatbuffers::Parser and GenerateText:

• load .fbs / .bfbs
• JSON -> FlatBuffer binary
• FlatBuffer binary -> JSON

Repo layout

• cpp/: C++ binding source (pybind11)
• src/ark_fbs/: Python package wrapper + typing stubs
• third_party/flatbuffers/: your fork of FlatBuffers as a git submodule (recommended)

Local build (editable)

uv sync --group dev
uv pip install -e .

Usage

import ark_fbs

s = ark_fbs.Schema.from_fbs_text(
    "namespace t; table A { x:int; } root_type A;"
)
b = s.json_to_binary('{"x":1}')
print(s.binary_to_json(b))

Wheels / PyPI

CI uses cibuildwheel to produce wheels for multiple CPython versions and architectures. See .github/workflows/wheels.yml.
