hgraph

A clean-slate, C++-first implementation of the hgraph functional-reactive time-series runtime. The C++ runtime is the source of truth. Python provides wiring compatibility and supports Python-authored nodes running inside that runtime.

Python package

The C++-backed runtime is published under the hgraph distribution name:

python -m pip install hgraph

The distribution exposes the hgraph import package and the native _hgraph extension. Version 0.8.0 replaces the Python-first runtime maintained on the release/0.5 branch. One wheel per supported platform covers CPython 3.12 and later through the CPython stable ABI. The supported Python and platform policy is recorded in docs/source/developer_guide/release_readiness.rst.

Build & test

cmake -S . -B build                 # configure (fmt + Catch2 fetched if absent)
cmake --build build -j              # build hgraph_core + tests
ctest --test-dir build --output-on-failure

Requires a C++23 compiler and CMake >= 3.25. Python/nanobind are not needed for the default build (bindings are opt-in via -DHGRAPH_BUILD_PYTHON_BINDINGS=ON).

First-party extensions

First-party extensions are co-developed in extensions/ but remain separate native and Python distributions. Kafka is built in-tree for development with -DHGRAPH_BUILD_KAFKA_EXTENSION=ON, or independently from extensions/kafka/ against an installed hgraph SDK. Its wheel is selected from the uv workspace after making that matching SDK discoverable:

CMAKE_PREFIX_PATH=/path/to/hgraph/sdk \
  uv build --wheel --package hgraph-kafka --python 3.12

The core build does not enable the extension by default and does not acquire a Kafka or librdkafka dependency.

Documentation

Sphinx docs live under docs/source (uv sync --extra docs, then uv run sphinx-build -W -b html docs/source docs/_build/html):

  • User guide — start at docs/source/user_guide/quick_start.rst, then the authoring/testing guides for nodes, graphs, and the eval_node harness.
  • Developer guide — the authoritative design records (docs/source/developer_guide/): architecture, data structures, wiring, nested graphs, mesh, services, error handling, operators, roadmap.

Contributing / AI sessions

  • AGENTS.md — canonical project direction: goals, build philosophy, source layout, dependency policy, git hygiene.
  • CLAUDE.md — the operational working guide: the enforced design-first workflow (docs change in the same commit as code), guardrails, architecture map, and current state.
