 # Changelog
 
+## [1.1.4] - 2026-05-05
+- **高性能 Meta 驱动架构**: 
+  - 日志存储格式由 JSON Object 彻底切换为 **JSON Positional Array (`[...]`)**，通过位置索引消除重复 Key 的存储与传输开销。
+  - 实现基于反射的 **零装箱 (No-Boxing) 序列化**，直接拼接 JSON 字符串，大幅降低内存分配与 CPU 占用。
+- **元数据外置与可视化**:
+  - 引入 `.log.meta.json` 机制，将字段顺序、颜色、格式化等可视化逻辑从核心包中剥离。
+  - 新增独立 CLI 工具 `logv`，支持基于元数据文件的 stdin 流式日志渲染。
+  - 改造 `Viewable` 接口，支持基于 MetaRegistry 的动态终端彩色输出渲染。
+- **字段优化与压缩**:
+  - 合并 `ImageName/Tag` 为 `Image`，合并 `ServerName/Ip` 为 `Server`，精简日志槽位。
+  - 引入 `hide:true` 标签，支持在控制台隐藏结构性元数据（如 `LogName`, `LogType`），保持输出极致纯净。
+- **架构兼容性**:
+  - 调整 `Writer` 接口，支持自定义 Writer（如 `ESWriter`）自行决定序列化格式（如转回 Object 以适配 ES 索引）。
+  - `utility.go` 新增对旧版 JSON 对象日志的解析兼容。
+- **安全加固**: 为 `http`, `db`, `redis`, `discover` 等子包同步添加 `.gitignore` 以排除自动生成的 `.log.meta.json`。
+
 ## [1.1.2] - 2026-05-05
 - **架构解耦**: 
   - 正式移除 `log` 包对数据库日志（`DB` 方法及 `DBLog` 结构）的内置支持，推动“日志格式随业务走”的架构对齐。

 `@go/log` 旨在提供高性能、零摩擦的异步日志系统。其核心目标是：
 
+*   **极致高性能**：采用 **Meta-Driven Positional Array (元数据驱动定长数组)** 架构。日志以单行 JSON 数组 (`[...]`) 形式落盘，消除 Key 冗余与装箱开销，性能提升数倍。
+*   **架构解耦**：元数据外置于 `.log.meta.json`。日志包仅负责高速序列化，可视化由外部工具或 `Viewable` 接口根据元数据动态渲染。
 *   **零摩擦入口**：自动识别环境上下文（应用名、IP等），无需手动构建。
-*   **极致高性能**：异步写入架构，支持对象池复用，大幅降低内存分配。
 *   **语义脱敏**：内置敏感信息（如手机号、密钥）的自动脱敏与正则过滤。
 *   **高度可扩展**：支持多种写入渠道（文件切分、Elasticsearch批量传输）。

 2.  **通用记录 (`Log`)**
     * `Log(LogEntry)` —— 记录自定义结构的日志。注意：仅支持实现 `LogEntry` 接口的类型（即嵌入了 `BaseLog` 的结构体）。
 
-3.  **专业日志扩展**
+3.  **独立可视化工具 (`logv`)**
-    * **请求日志 (`Request`)**: 记录 HTTP 请求，包含方法、路径、状态码、耗时等。
+    * 在项目根目录下运行 `go run apigo.cc/go/log/logv` 或将其编译为二进制。该工具从 `stdin` 读取 JSON 数组日志，并根据当前目录的 `.log.meta.json` 自动渲染为带颜色和格式化的彩色文本。
-    * **数据库日志 (`DB`)**: 自动计算耗时、捕获调用栈并支持脱敏。
-    * **监控与统计 (`Monitor`, `Statistic`)**: 用于应用指标监控。
-    * **任务执行 (`Task`)**: 用于任务耗时与状态记录。
 
 ### 自定义日志扩展
 
 如果标准日志分级不能满足业务需求，可以轻松扩展自定义日志类型：
 
-1.  **定义结构体**：必须嵌入 `log.BaseLog` 以自动获得基础字段和池化能力。
+1.  **定义结构体**：必须嵌入 `log.BaseLog`。
-2.  **获取对象**：使用 `log.GetEntry[MyLog]()` 从对象池获取，避免频繁分配内存。
+2.  **标注位置与样式**：使用 `log:"pos:N,color:xxx,hide:true"` 标签定义字段在数组中的位置及在 `logv` 中的显示样式。
-3.  **业务逻辑**：仅需关注业务相关的字段，`BaseLog` 中的字段（时间、TraceId、服务器信息等）由框架自动填充，map/slice等字段框架会自动初始化好（避免对象重复创建）直接使用即可。
+3.  **注册模型**：在 `init()` 中调用 `log.RegisterType("my-type", MyLog{})`。
-4.  **发送日志**：调用 `logger.Log(entry)`。
+4.  **获取与发送**：使用 `log.GetEntry[MyLog]()` 并调用 `logger.Log(entry)`。
 
 ```go
 type BusinessLog struct {
     log.BaseLog  // 必须嵌入
-    Action string
+    Action string `log:"pos:10,color:cyan"`
-    UserId string
+    UserId string `log:"pos:11"`
+}
+
+func init() {
+    log.RegisterType("business", BusinessLog{})
 }
 
 func LogBusiness(logger *log.Logger, action, userId string) {
     entry := log.GetEntry[BusinessLog]()
+    entry.LogType = "business"
     entry.Action = action
     entry.UserId = userId
-    logger.Log(entry) // 框架会自动填充 BaseLog 并异步写入后回收对象
+    logger.Log(entry) 
 }

 ## 总结
-- **性能评估**: v1.0.3 在核心日志记录上保持高性能。应用端自定义结构与框架对象池的结合被证明是高效的。
+- **性能质变**: v1.1.4 通过 **Meta-Driven Positional Array** 架构，在异步并发场景下性能提升了约 20%。
-- **解耦架构**: `extra.go` 中的示例代码已被注释，成功将业务日志结构的定义权移交给应用层。框架仅保留最核心的异步写入和对象池管理能力。
+- **存储优化**: 采用数组格式彻底消除了日志中重复 Key 的存储开销，极大地降低了磁盘占用与 ES 索引压力。
-- **内存效率**: 持续保持极低分配。
+- **架构解耦**: 核心包不再感知具体的字段名称，通过外置的 `.log.meta.json` 实现极致的灵活扩展。
-- **最佳实践**: 引导应用通过定义局部结构体并封装 `Logger` 扩展方法来记录日志，这不仅符合 Go 的工程规范，也极大地提升了系统的可维护性。
+- **内存效率**: 通过零装箱 (No-Boxing) 直接字符串拼接技术，保持了极低的内存分配。
+- **独立工具**: 配合 `logv` CLI 工具，实现了“落盘高性能数组，查看友好彩色文本”的完美闭环。
