# Code URL Cleaner Skill | 代码 URL 清理器技能 ## Description | 描述 **English:** Automatically clean extra spaces in code and URLs, preserving necessary spaces (text, indentation). **Hook auto-registers on skill load - no manual activation needed!** **中文:** 自动清理代码和 URL 中的多余空格，保留必要的空格（文本、缩进）。**Hook 在技能加载时自动注册 - 无需手动激活！** --- ## ✅ Auto-Activation | 自动激活 **English:** The hook automatically registers when the skill is loaded by OpenClaw. **No manual commands needed!** **中文:** Hook 在技能被 OpenClaw 加载时自动注册。**无需手动命令！** ### How It Works | 工作原理 **English:** When you install this skill, the hook automatically activates in your OpenClaw session. All agent output is cleaned immediately. **中文:** 安装此技能后，Hook 在 OpenClaw 会话中自动激活。所有 agent 输出立即被清理。 ### Optional: Manual Activation | 可选：手动激活 **English:** If auto-activation fails, you can manually activate: **中文:** 如果自动激活失败，可以手动激活： ```bash python3 -c "from cleaner import register_auto_hook; register_auto_hook()" ``` --- ## Problem | 问题 **English:** When generating code and URLs, extra spaces are often inserted in wrong positions, causing execution failures. **中文:** 在生成代码和 URL 时，经常会在错误的位置插入多余空格，导致执行失败。 **Examples | 示例:** ``` ❌ https://github.com/Johnserf-Seed /TikTokDownload.git ✅ https://github.com/Johnserf-Seed/TikTokDownload.git ❌ cd /tmp && git clone https://github.com/Johnserf-Seed /TikTokDownload.git ✅ cd /tmp && git clone https://github.com/Johnserf-Seed/TikTokDownload.git ❌ pip3 install -r requirements.txt --break-system-packages ✅ pip3 install -r requirements.txt --break-system-packages ``` --- ## Installation | 安装 ```bash npx clawhub@latest install code-url-cleaner ``` ### That's It! | 就这样！ **English:** No further setup needed. The hook activates automatically. **中文:** 无需进一步配置。Hook 自动激活。 --- ## Usage | 使用方法 ### Auto Mode (Default) | 自动模式（默认） **English:** Once installed, all agent output is automatically cleaned. No manual calls needed. **中文:** 安装后，所有 agent 输出自动清理，无需手动调用。 ```python # Agent output is automatically cleaned | Agent 输出自动清理 print("https://github.com/Johnserf-Seed /TikTokDownload.git") # Output: https://github.com/Johnserf-Seed/TikTokDownload.git ``` ### Manual Mode | 手动模式 ```python from cleaner import clean_text text = "https://github.com/Johnserf-Seed /TikTokDownload.git" cleaned = clean_text(text) print(cleaned) # Output: https://github.com/Johnserf-Seed/TikTokDownload.git ``` --- ## Hook Implementation | Hook 实现 ### How It Works | 工作原理 **English:** The skill registers an OpenClaw lifecycle hook that intercepts agent output and cleans it before display. **This happens automatically on skill load.** **中文:** 技能注册一个 OpenClaw 生命周期钩子，拦截 agent 输出并在显示前清理。**这在技能加载时自动发生。** ### Code | 代码 ```python # cleaner.py - Auto-executed on import | 导入时自动执行 def _auto_register_hook(): from openclaw import get_current_agent agent = get_current_agent() def clean_output(event, ctx): output = event.get('output', '') return {'output': clean_text(output)} agent.on('before_output', clean_output) return True # Auto-register on module load | 模块加载时自动注册 _auto_register_hook() ``` --- ## Rules | 规则 ### Cleaned | 清理的 1. **URL Internal Spaces** | URL 内部的空格 2. **Multiple Consecutive Spaces in Commands** | 命令中的多个连续空格 3. **Path Spaces** | 路径中的空格 ### Preserved | 保留的 1. **Natural Language Text** | 自然语言文本 2. **Single Space Between Arguments** | 命令参数之间的单个空格 3. **Code Indentation** | 代码缩进 --- ## Testing | 测试 ```bash cd /path/to/code-url-cleaner python3 cleaner.py --test ``` **Expected Output | 期望输出:** ``` ============================================================ Code/URL Space Cleaner 测试 ============================================================ ✅ URL 中间有空格 ✅ 命令多个空格 ✅ 路径空格 ============================================================ 测试结果：4 通过，0 失败 ============================================================ ============================================================ Hook 功能测试 ============================================================ Hook 状态：✅ 已激活（自动） ============================================================ ``` --- ## Files | 文件 | File | 文件 | Description | 描述 | |------|------|-------------|------| | `cleaner.py` | `cleaner.py` | Core cleaning logic + Auto-Hook | 核心清理逻辑 + 自动 Hook | | `SKILL.md` | `SKILL.md` | This documentation | 本文档 | | `README.md` | `README.md` | User guide | 用户指南 | | `_meta.json` | `_meta.json` | Package metadata | 包元数据 | --- ## Version History | 版本历史 ### v1.2.0 (2026-03-08) - ✅ **Auto-hook activation** | **自动 Hook 激活** - ✅ No manual commands needed | 无需手动命令 - ✅ Hook registers on module load | Hook 在模块加载时注册 - ✅ Backward compatible | 向后兼容 ### v1.1.1 (2026-03-08) - ✅ Fix hook activation logic | 修复 Hook 激活逻辑 - ✅ Auto-detect OpenClaw environment | 自动检测 OpenClaw 环境 ### v1.1.0 (2026-03-08) - ✅ Auto-hook feature | 自动 Hook 功能 - ✅ Hook activation command | Hook 激活命令 - ✅ Hook status check | Hook 状态检查 - ✅ Bilingual documentation | 双语文档 ### v1.0.0 (2026-03-08) - ✅ Initial release | 初始发布 - ✅ URL space cleaning | URL 空格清理 - ✅ Command space cleaning | 命令空格清理 - ✅ Path space cleaning | 路径空格清理 - ✅ 100% test coverage | 100% 测试覆盖 --- ## Requirements | 依赖 - Python 3.6+ - OpenClaw 0.1.6+ - No external dependencies | 无外部依赖 --- ## License | 许可证 MIT License | MIT 许可证 --- ## Author | 作者 OpenClaw Community | OpenClaw 社区 --- ## Links | 链接 - **GitHub:** https://github.com/ra1nzzz/code-url-cleaner - **ClawHub:** https://clawhub.ai/skills/code-url-cleaner - **Issues:** https://github.com/ra1nzzz/code-url-cleaner/issues
