# 贡献指南
感谢你为 Claw Code 做出贡献。
## 开发设置
- 安装稳定的 Rust 工具链。
- 在此 Rust 工作区的仓库根目录下进行开发。如果你从父仓库根目录开始，请先执行 `cd rust/`。
## 构建
```bash
cargo build
cargo build --release
```
## 测试与验证
在开启 Pull Request 之前，请运行完整的 Rust 验证集：
```bash
cargo fmt --all --check
cargo clippy --workspace --all-targets -- -D warnings
cargo check --workspace
cargo test --workspace
```
如果你更改了行为，请在同一个 Pull Request 中添加或更新相关的测试。
## 代码风格
- 遵循所修改 crate 中的现有模式，而不是引入新的风格。
- 使用 `rustfmt` 格式化代码。
- 确保你修改的工作区目标的 `clippy` 检查通过。
- 优先采用针对性的 diff，而不是顺便进行的重构。
## Pull Request
- 从 `main` 分支拉取新分支。
- 确保每个 Pull Request 的范围仅限于一个明确的更改。
- 说明更改动机、实现摘要以及你运行的验证。
- 在请求审查之前，确保本地检查已通过。
- 如果审查反馈导致行为更改，请重新运行相关的验证命令。

# Claw Code
Claw Code 是一个使用安全 Rust 实现的本地编程代理（coding-agent）命令行工具。它的设计灵感来自 **Claude Code**，并作为一个**净室实现（clean-room implementation）**开发：旨在提供强大的本地代理体验，但它**不是** Claude Code 的直接移植或复制。
本项目为不同实现语言和任务目标进行了重构版本，并分布在不同的分支中。
Rust 工作区是当前主要的产品界面。`claw` 二进制文件在单个工作区内提供交互式会话、单次提示、工作区感知工具、本地代理工作流以及支持插件的操作。
## 🚀 分支信息
- **[源分支](https://git.asfmq.cn/fmq/claudecode/src/branch/nodejs)**: 原始的nodejs版本
- **[Python 分支](https://git.asfmq.cn/fmq/claudecode/src/branch/python)**: 包含原始的 Python 净室重写版本及配套编排工具。
- **[Rust 分支](https://git.asfmq.cn/fmq/claudecode/src/branch/rust)**: 包含高性能的 Rust 实现版，包括 `claw` 命令行工具和会话运行时。
## 当前状态
## 🛠 项目布局
- **版本：** `0.1.0`
- **发布阶段：** 初始公开发布，源码编译分发
- **主要实现：** 本仓库中的 Rust 工作区
- **平台焦点：** macOS 和 Linux 开发工作站
- `main`: 当前主入口，仅包含项目结构说明。
- `nodejs`: 原始的nodejs版本
- `python`: Python 源代码、测试及任务定义。
- `rust`: Rust 工作区，包含 API、Runtime、CLI 等所有核心 crate。
## 安装、构建与运行
### 准备工作
- Rust 稳定版工具链
- Cargo
- 你想使用的模型的提供商凭据
### 身份验证
兼容 Anthropic 的模型：
```bash
export ANTHROPIC_API_KEY="..."
# 使用兼容的端点时可选
export ANTHROPIC_BASE_URL="https://api.anthropic.com"
```
Grok 模型：
```bash
export XAI_API_KEY="..."
# 使用兼容的端点时可选
export XAI_BASE_URL="https://api.x.ai"
```
也可以使用 OAuth 登录：
```bash
cargo run --bin claw -- login
```
### 本地安装
```bash
cargo install --path crates/claw-cli --locked
```
### 从源码构建
```bash
cargo build --release -p claw-cli
```
### 运行
在工作区内运行：
```bash
cargo run --bin claw -- --help
cargo run --bin claw --
cargo run --bin claw -- prompt "总结此工作区"
cargo run --bin claw -- --model sonnet "审查最新更改"
```
运行发布版本：
```bash
./target/release/claw
./target/release/claw prompt "解释 crates/runtime"
```
## 支持的功能
- 交互式 REPL 和单次提示执行
- 已保存会话的检查和恢复流程
- 内置工作区工具：shell、文件读/写/编辑、搜索、网页获取/搜索、待办事项和笔记本更新
- 斜杠命令：状态、压缩、配置检查、差异（diff）、导出、会话管理和版本报告
- 本地代理和技能发现：通过 `claw agents` 和 `claw skills`
- 通过命令行和斜杠命令界面发现并管理插件
- OAuth 登录/注销，以及从命令行选择模型/提供商
- 工作区感知的指令/配置加载（`CLAW.md`、配置文件、权限、插件设置）
## 当前限制
- 目前公开发布**仅限源码构建**；此工作区尚未设置 crates.io 发布
- GitHub CI 验证 `cargo check`、`cargo test` 和发布构建，但尚未提供自动化的发布打包
- 当前 CI 目标为 Ubuntu 和 macOS；Windows 的发布就绪性仍待建立
- 一些实时提供商集成覆盖是可选的，因为它们需要外部凭据 and 网络访问
- 命令界面可能会在 `0.x` 系列期间继续演进
## 实现现状
Rust 工作区是当前的产品实现。目前包含以下 crate：
- `claw-cli` — 面向用户的二进制文件
- `api` — 提供商客户端和流式处理
- `runtime` — 会话、配置、权限、提示词和运行时循环
- `tools` — 内置工具实现
- `commands` — 斜杠命令注册和处理程序
- `plugins` — 插件发现、注册和生命周期支持
- `lsp` — 语言服务器协议支持类型和进程助手
- `server` 和 `compat-harness` — 支持服务和兼容性工具
## 路线图
- 发布打包好的构件，用于公共安装
- 添加可重复的发布工作流和长期维护的变更日志（changelog）规范
- 将平台验证扩展到当前 CI 矩阵之外
- 添加更多以任务为中心的示例和操作员文档
- 继续加强 Rust 实现的功能覆盖并磨炼用户体验（UX）
## 发行版本说明
- 0.1.0 发行说明草案：[`docs/releases/0.1.0.md`](docs/releases/0.1.0.md)
## 许可
有关许可详情，请参阅仓库根目录。

# Claw Code 0.1.0 发行说明（草案）
## 摘要
Claw Code `0.1.0` 是当前 Rust 实现的第一个公开发布准备里程碑。Claw Code 的灵感来自 Claude Code，并作为一个净室（clean-room）Rust 实现构建；它不是直接的移植或复制。此版本专注于可用的本地 CLI 体验：交互式会话、非交互式提示词、工作区工具、配置加载、会话、插件以及本地代理/技能发现。
## 亮点
- Claw Code 的首个公开 `0.1.0` 发行候选版本
- 作为当前主要产品界面的安全 Rust 实现
- 用于交互式和单次编码代理工作流的 `claw` CLI
- 内置工作区工具：用于 shell、文件操作、搜索、网页获取/搜索、待办事项跟踪和笔记本更新
- 斜杠命令界面：用于状态、压缩、配置检查、会话、差异/导出以及版本信息
- 本地插件、代理和技能的发现/管理界面
- OAuth 登录/注销以及模型/提供商选择
## 安装与运行
此版本目前旨在通过源码构建：
```bash
cargo install --path crates/claw-cli --locked
# 或者
cargo build --release -p claw-cli
```
运行：
```bash
claw
claw prompt "总结此仓库"
```
## 已知限制
- 仅限源码构建分发；尚未发布打包好的发行构件
- CI 目前覆盖 Ubuntu 和 macOS 的发布构建、检查和测试
- Windows 的发布就绪性尚未建立
- 部分集成覆盖是可选的，因为需要实时提供商凭据和网络访问
- 公开接口可能会在 `0.x` 版本系列期间继续演进
## 推荐的发行定位
将 `0.1.0` 定位为 Claw Code 当前 Rust 实现的首个公开发布版本，面向习惯于从源码构建的早期采用者。功能表面已足够广泛以支持实际使用，而打包和发布自动化可以在后续版本中继续改进。
## 用于此草案的验证
- 通过 `Cargo.toml` 验证了工作区版本
- 通过 `cargo metadata` 验证了 `claw` 二进制文件/包路径
- 通过 `cargo run --quiet --bin claw -- --help` 验证了 CLI 命令表面
- 通过 `.github/workflows/ci.yml` 验证了 CI 覆盖范围
