python-3.10-dredd 1.1.0

Python 3.10+ language plugin for semver-dredd

python-3.10-dredd

Python 3.10+ language plugin for semver-dredd.

Installation

# Install via the core package extra
pip install "semver-dredd[python]"

# Or install the plugin distribution directly
pip install python-3.10-dredd

Or install from local path (development):

pip install ./plugins/python-3.10-dredd

Usage

Once installed, the plugin is automatically discovered by semver-dredd:

# List plugins to verify installation
semver-dredd plugin list
semver-dredd plugin info python

# Generate a snapshot for an importable module/package
semver-dredd snapshot --plugin python --path mypackage --version 1.0.0

# Use with init/status/bake commands
semver-dredd init mypackage --plugin python --version 1.0.0
semver-dredd status mypackage --plugin python
semver-dredd bake mypackage --plugin python

For the Python plugin, --path/positional source values are importable module or package names (for example mypackage or mypackage.api), not filesystem globs.

If .semver.yaml already records plugin: python and source.path, follow-up commands can often omit the explicit path/plugin:

semver-dredd status --details
semver-dredd bake

How it works

This plugin uses Python's inspect module to introspect Python modules and extract:

• Public functions and their signatures
• Public classes, their methods, and fields
• Support for dataclasses, namedtuples, Pydantic models, and __slots__

Scope: include / exclude

include and exclude items are module/package dotted names (not filesystem globs), matched recursively (an item matches itself and any of its dotted-prefix descendants):

include: [mypackage.api]
exclude: [mypackage.api.internal]

• Empty include (or omitted) analyzes the whole configured module's API surface, exactly as without scope.
• A non-empty include switches to allow-list mode: only listed modules/submodules (and their descendants) are analyzed.
• exclude is applied after include.
• If the root module defines __all__, scope recursion is skipped entirely — only the names listed in __all__ are analyzed, matching plain Python visibility rules. include/exclude do not apply in this mode.
• If __all__ is absent, the plugin recursively discovers public (non _-prefixed) submodules and merges their public members into the snapshot. include matching nothing produces an empty snapshot API (logged as a warning) rather than falling back to no-scope behavior.

Requirements

• Python 3.10+
