LiteyukiBot v7

LiteyukiBot v7 is a protocol-neutral chatbot kernel for CPython 3.14. Native plugins run in the core process; separately distributed framework hosts and LiteyukiBot v6 plugins run in supervised child runtimes.

The v7 branch is a clean rewrite. The main branch remains the maintenance line for v6 and is not merged wholesale into v7.

The current pre-release is liteyukibot-v7==7.0.0a5. Kernel stabilization, the first bounded compatibility phase, and the first-party plugin foundation are complete. Runtime protocol v3 remains an alpha contract and may change under ADR 0011 before the first stable release.

Current Foundation

• immutable TOML/JSON configuration with ordered includes, environment overrides, and CLI overrides;
• Yukilog 1.x facade backed by Loguru, including structured child logs;
• native plugin entry points, async lifecycle hooks, private storage, managed tasks, and versioned services;
• bounded protocol-neutral event/action dispatch with per-conversation order;
• authenticated framed JSON IPC and supervised subprocess runtimes;
• runtime-host discovery plus a deliberately bounded v6 compatibility shim;
• local authenticated CLI control and an optional loopback-only HTTP status API.
• read-only kernel status plus separately distributable capability, command, resource-management, profile, help, and protected-status plugins.

Requirements

• CPython 3.14+
• uv
• network access for uv to resolve PyPI dependencies

Yukilog 1.x is installed from PyPI; no sibling checkout is required. The v7 kernel distribution on PyPI is named liteyukibot-v7 and provides the liteyukibot namespace. The separately installed v6 runtime provides the liteyuki compatibility namespace.

Tool Installation

Install the v7 CLI into uv's isolated tool environment:

uv tool install --python 3.14 liteyukibot-v7
liteyuki init
liteyuki run

The commands operate on the current directory by default. Use liteyuki --workspace PATH ... to select another project. liteyukibot and ly are equivalent executable aliases. Upgrade only the v7 tool with:

uv tool upgrade --python 3.14 liteyukibot-v7

This does not replace a separately installed v6 liteyukibot distribution.

uv sync --locked
uv run liteyuki check
uv run liteyuki run

Optional kernel integrations are installed explicitly:

uv sync --extra yaml
uv sync --extra http

Framework hosts are independent packages. Install NoneBot2 with an adapter:

uv add "liteyukibot-v7-runtime-nonebot[onebot]"
# or: uv add "liteyukibot-v7-runtime-nonebot[satori]"

Install bounded v6 compatibility when legacy plugins are required:

uv add "liteyukibot-v7-runtime-v6"

Install the Essentials command layer with:

uv add "liteyukibot-v7-essentials==0.2.0a2"

This resolves liteyukibot-v7-commands and liteyukibot-v7-permissions; enable all three plugin IDs in configuration.

The optional profile layer adds persistent per-bot user nickname and language preferences. Install liteyukibot-v7-profile to resolve resources, then enable liteyukibot.resources and liteyukibot.profile before Essentials. Profile is a business plugin: its SQLite database is private to the plugin, and resources only supplies the declaration, command, and authorization boundary.

Create a project-local configuration with uv run liteyuki init; use liteyuki.example.toml as a configuration reference. CLI overrides must precede the subcommand, for example:

uv run liteyuki --config local.toml --set logging.level=DEBUG check

Initialization, encrypted runtime secrets, upgrade recovery, and configuration provenance are documented in docs/configuration.md.

Docker

The v7 image can be built locally with the optional YAML, HTTP, NoneBot, OneBot, Satori, and v6 compatibility runtime packages. It runs as a non-root user. GHCR publication is currently paused; the Docker workflow validates builds without pushing.

docker build -t liteyukibot:v7-local .
docker run --rm liteyukibot:v7-local version

When /app/liteyuki.toml is absent, the container creates the versioned default template once. Mount a configuration at that path to control a deployment, and persist /app/data, /app/cache, and /app/plugins.

Development

uv sync --locked --all-packages
uv run ruff check src tests scripts examples packages
uv run mypy
uv run pytest
uv build
uv build --all-packages --out-dir dist/workspace --clear
uv build --project examples/native-plugin --out-dir dist/examples

The architecture overview is documented in docs/architecture/v7.md; accepted architecture contracts are indexed in docs/adr/README.md; the v6 compatibility boundary is documented in docs/migration-v6.md.

Release maintainers should follow docs/development/releasing.md.

Plugin and runtime authors should start with the installable examples and their focused guides:

• examples/native-plugin and docs/development/native-plugins.md;
• examples/custom-runtime and docs/development/custom-runtimes.md.
