dazzlecmd-lib 0.8.55

Engine library for dazzlecmd-pattern tool aggregators

dazzlecmd-lib

The aggregator/dispatch engine behind the dazzlecmd pattern: tool discovery, kit/FQCN dispatch, the runtime registry, and the DazzleEntity continuum object model. It is a standalone framework — it does not require dazzlecmd to be installed; dazzlecmd is just its first consumer.

Build your own dz-pattern CLI in ~10 lines

from dazzlecmd_lib import AggregatorEngine

def main():
    engine = AggregatorEngine(
        name="my-tools",
        command="mt",
        tools_dir="tools",
        manifest=".mt.json",
        version_info=("1.0", "1.0.0_main_1"),
    )
    return engine.run()

That gives you mt list, mt info <tool>, mt kit, mt version, mt tree, and mt setup for free. Customize via the meta-command registry:

engine.meta_registry.register("mycmd", parser_factory, handler)
engine.meta_registry.override("list", handler=my_custom_list)
engine.meta_registry.unregister("tree")

What's inside

• AggregatorEngine — a configurable CLI tool aggregator (discovery + dispatch).
• FQCNIndex — dual-index lookup for Fully-Qualified Collection Names (kit:tool, aggregator:kit:tool).
• RunnerRegistry — extensible runtime dispatch (Python, PowerShell, passthrough, …).
• MetaCommandRegistry — per-engine meta-command registry (override/extend the stock commands).
• default_meta_commands — stock list / info / kit / version / tree / setup.
• ConfigManager — per-aggregator config reading/writing.
• The mode subsystem — embedded / submodule / symlink tool-source detection and the dev↔publish toggle.
• The DazzleEntity object model and the kit/continuum machinery (built on the dazzle-lib bedrock).

The DazzleLib stack

dazzlecmd-lib is an upper-layer member of the DazzleLib library stack. It builds on the bedrock and file-ops layers:

• dazzle-lib — Protocols, TypedDict schemas, the continuum/state primitives.
• dazzle-filekit — cross-platform file operations + metadata preservation.
• unctools — UNC / drive-type path tools (Windows volume routing).

Consumers built on dazzlecmd-lib include dazzlecmd, amdead, and wtf-windows.

Install

pip install dazzlecmd-lib

Developing alongside a consumer (editable, shadow-proof)

When a consumer (e.g. dazzlecmd) is installed from PyPI, its dazzlecmd-lib dependency comes from PyPI too. To develop against a local checkout, install it editable with --no-deps so the local copy wins over any PyPI copy:

pip install -e C:/code/dazzlecmd-lib --no-deps

Versioning

Pre-1.0: the library reserves the right to make breaking changes during MINOR bumps until 1.0. Consumers should pin dazzlecmd-lib>=0.X.Y,<1.0.

History through 0.8.55 lives in the dazzlecmd monorepo git log (under packages/dazzlecmd-lib/), from which this repository was extracted on 2026-06-24. See CHANGELOG.md.
