erdantic - pypi Package Compare versions

Comparing version 1.2.0 to 1.2.1

AGENTS.md

+# AGENTS.md
+
+## Interaction Contract
+
+- For questions, planning, tradeoff analysis, or brainstorming: do not edit files and do not run modifying commands. Read-only commands are allowed.
+- In those cases, respond with analysis, options, or a plan only.
+- Implement only when the user gives an explicit execution instruction (`implement`, `apply`, `proceed`, or equivalent).
+- If intent is ambiguous, ask one short clarification question.
+- Never infer implementation intent from context alone.
+- Silence is not consent to edit code.
+
+## Working Style
+
+- Make minimal, focused diffs.
+- Do not modify unrelated files.
+- Avoid broad refactors unless requested.
+
+## Project Map
+
+- Library code: `erdantic/`
+- Plugins: `erdantic/plugins/`
+- CLI: `erdantic/cli.py`
+- Tests: `tests/`
+- Static test assets: `tests/assets/`
+- Asset generators: `tests/scripts/generate_static_assets.py`, `tests/scripts/generate_pydantic_with_defaults_assets.py`
+
+## Commands
+
+- Use `pixi run` or `just` for project commands; avoid direct `python`/`python3`/`pytest`/`ruff`/`mypy` unless explicitly requested.
+- Setup/sync: `just sync`
+- Lint: `just lint`
+- Format: `just format`
+- Typecheck: `just typecheck`
+- Tests (default py3.13): `just test`
+- Tests (specific Python): `just python=3.12 test`
+- Full matrix: `just test-all`
+- Test commands accept pytest args, e.g.:
+  - `just test tests/test_against_assets.py -k pydantic`
+  - `just test-all tests/test_against_assets.py`
+
+## Testing Expectations
+
+- Behavior changes must include or update tests.
+- If expected rendered outputs change, ask for user permission before running `just generate-static-assets`.
+- Review `tests/assets/` diffs carefully.
+- Prefer targeted test runs while iterating, then run the relevant broader suite.
+
+## Notes
+
+- Graphviz/PyGraphviz is required. Pixi activation automatically runs `scripts/fix_graphviz.sh`.
+- Python-version differences matter (`3.9` through `3.14`).
+- Some tests validate generated artifacts, not just runtime behavior.

CHANGELOG.md

 # erdantic Changelog
 
+## v1.2.1 (2026-02-15)
+
+- Added official support for Python 3.14. ([PR #164](https://github.com/drivendataorg/erdantic/pull/164))
+    - _Note_: The `pydantic_v1` plugin is disabled when running on Python 3.14+, as Pydantic has dropped support for its V1 legacy module.
+    - _Note_: Python 3.14's internal representation of `typing.Union` and `typing.Optional` have changed, such that they will always render using the `|` operator.
