# AI Coding Context: @go/time
|
||||
|
||||
本索引供 AI 模型理解 `@go/time` 的设计逻辑与调用原则,以生成符合本项目“极简、无摩擦”哲学的代码。
|
||||
|
||||
## 🤖 AI 行为准则
|
||||
|
||||
1. **优先使用包级函数**:在处理时间转换时,直接使用 `time.Parse(v)`,不要手动编写复杂的 Layout 探测逻辑。
|
||||
2. **默认本地时间**:理解 `time.Parse` 总是返回 **`time.Local`**。如果需要生成展示代码,无需再手动调用 `.In(time.Local)`。
|
||||
3. **推荐直观 Layout**:在调用 `time.Format()` 时,优先推荐使用 `YYYY-MM-DD HH:mm:ss` 等直观占位符。
|
||||
4. **使用 Add DSL 替代手动计算**:在需要进行时间偏移(如“30天后”、“下个月”)时,推荐使用 `time.Add("+30D", v)` 或 `time.Add("+1M", v)`。
|
||||
|
||||
## 🛠 关键 API 逻辑约定
|
||||
|
||||
| 函数 | 逻辑特征 |
|
||||
| :--- | :--- |
|
||||
| `Parse(v any)` | **全能解析 & 归一化**。支持 timestamp (s/ms/us/ns), RFC3339, JS Date, 中文等。解析结果统一转为 `time.Local`。失败返回 `time.Now()`。 |
|
||||
| `Format(layout, v)` | **人性化 Layout**。将 `YYYY-MM-DD` 等自动转为 Go Layout。 |
|
||||
| `Add(expr, v)` | **DSL 计算**。支持 `Y, M, D, h, m, s, ms, us, ns`。 |
|
||||
| `Today() / Yesterday()` | 返回对应日期 **00:00:00** (Local) 的 `time.Time`。 |
|
||||
|
||||
## 🧩 支持的字符串模式 (Pattern Reference)
|
||||
|
||||
AI 在推荐代码时可以放心使用以下格式:
|
||||
- **ISO**: `"2024-01-01T15:00:00Z"`, `"2024-01-01T15:00:00+08:00"`
|
||||
- **Standard**: `"2024-01-01 15:00:00"`, `"2024/01/01 15:00"`, `"2024.01.01"`
|
||||
- **Chinese**: `"2024年1月1日"`, `"下午3点30分"`, `"15时30分"`
|
||||
- **Timestamp**: `1713753600`, `1713753600000`

> **Maintainer Statement:** 本项目完全由 AI 维护。任何改动均遵循代码质量与性能的最佳实践。
|
||||
`@go/time` 是一个致力于“零心智负担”的时间处理库。它通过极简的 API 屏蔽了 Go 原生 `time` 包中繁琐的 Layout 记忆与类型转换,让时间解析、格式化与加减操作变得直观且高效。
|
||||
|
||||
## 🎯 设计哲学
|
||||
|
||||
`@go/timer` 是一个高性能的时间流管控引擎,专为构建健壮的微服务基础设施而设计。它不仅仅是计时器,更是一套处理并发、超时和重试的工具集。
|
||||
* **直观 Layout**:不再需要记忆 `2006-01-02 15:04:05`。使用 `YYYY-MM-DD HH:mm:ss` 等符合直觉的占位符。
|
||||
* **强力解析**:`Parse(v)` 几乎能吞下任何你丢给它的时间数据(时间戳、ISO、RFC3339、中文、JS Date 字符串等),并自动归一化为本地时间。
|
||||
* **DSL 时间算术**:通过简洁的字符串表达式(如 `+1Y-2M`)进行复杂的时间偏移计算。
|
||||
* **零摩擦防御**:即使输入非法格式,也绝不 Panic,而是返回合理的默认值(如 `time.Now()`),确保服务高可用。
|
||||
|
||||
## 🚀 核心特性
|
||||
|
||||
### 1. 强力解析 `Parse(v any)`
|
||||
不再需要 layout,`Parse` 会自动探测以下格式并返回 `time.Time`。
|
||||
|
||||
**支持格式清单:**
|
||||
- **时间戳**: 10位(秒)、13位(毫秒)、16位(微秒)、19位(纳秒) 自动识别。
|
||||
- **标准日期**: `YYYY-MM-DD`, `YYYY/MM/DD`, `YYYY.01.02` (支持短年份如 `24-01-02`)。
|
||||
- **标准时间**: `YYYY-MM-DD HH:mm:ss`, `YYYY-MM-DDTHH:mm:ss.SSS` (支持空格或 `T` 分隔)。
|
||||
- **ISO/RFC3339**: `2024-01-01T00:00:00Z`, `2024-01-01T00:00:00+08:00`。
|
||||
- **紧凑格式**: `20240101153045`, `20240101`。
|
||||
- **中文格式**: `2024年01月01日 15点30分`, `下午3点`, `15时30分` (缺失部分自动补全)。
|
||||
- **常见 Web 格式**: JS Date 字符串, HTTP Header (RFC1123)。
|
||||
|
||||
**时区处理规则:**
|
||||
- **归一化**: 所有带时区信息的输入(如 UTC 或 +08:00)在解析后都会自动转换为当前服务器的 **`time.Local`**。
|
||||
- **无时区输入**: 默认视为 `time.Local`。
|
||||
|
||||
### 2. 语义化格式化 `Format(layout, v)`
|
||||
支持直观占位符:`YYYY`, `MM`, `DD`, `HH`, `mm`, `ss`, `ms`, `ZZ` (时区偏移)。
|
||||
|
||||
### 3. 时间加减 DSL `Add(expr, v)`
|
||||
- **单位**: `Y`(年), `M`(月), `D`(天), `h`, `m`, `s`, `ms`, `us`, `ns`。
|
||||
- **示例**: `+1Y-2M` (加一年减两个月), `-1D` (昨天), `+1h30m` (90分钟后)。
|
||||
|
||||
## 📦 安装
|
||||
|
||||
```bash
|
||||
go get apigo.cc/go/timer
|
||||
go get apigo.cc/go/time
|
||||
```
|
||||
|
||||
## 💡 核心功能
|
||||
|
||||
### 1. 耗时打点追踪 (Tracker)
|
||||
用于精准测量复杂业务流程中各环节的耗时。
|
||||
## 💡 快速开始
|
||||
|
||||
```go
|
||||
tk := timer.Start()
|
||||
// ... 业务步骤 1
|
||||
tk.Record("step1")
|
||||
// ... 业务步骤 2
|
||||
tk.Record("step2")
|
||||
import "apigo.cc/go/time"
|
||||
|
||||
fmt.Println(tk.Describe()) // [step1] 10ms; [step2] 20ms; Total: 30ms
|
||||
// 自动探测并转为本地时间
|
||||
tm := time.Parse("2025-06-23T15:30:45Z")
|
||||
|
||||
// 直观格式化
|
||||
fmt.Println(time.Format("YYYY-MM-DD HH:mm", tm))
|
||||
|
||||
// 语义加减
|
||||
nextMonth := time.Add("+1M", tm)
|
||||
```
|
||||
|
||||
### 2. 指数退避重试 (Retry)
|
||||
提供优雅的重试管控,防止由于短时波动导致的系统雪崩。
|
||||
|
||||
```go
|
||||
err := timer.Retry(func() error {
|
||||
return fetchRemoteData()
|
||||
}, timer.WithMaxRetries(3), timer.WithBackoff(100*time.Millisecond, 2.0))
|
||||
```
|
||||
|
||||
### 3. 高性能时间轮 (Time Wheel)
|
||||
在大规模定时任务场景下,相比原生 `time.Timer` 具有极低的 CPU 和内存开销。
|
||||
|
||||
```go
|
||||
tw := timer.NewTimeWheel(10*time.Millisecond, 100)
|
||||
tw.Start()
|
||||
|
||||
tw.AfterFunc(5*time.Second, func() {
|
||||
// 异步执行
|
||||
})
|
||||
```
|
||||
|
||||
### 4. 防抖与节流 (Debouncer & Throttler)
|
||||
控制高频事件的触发频率。
|
||||
|
||||
```go
|
||||
// 防抖:静止 1s 后执行
|
||||
d := timer.NewDebouncer(1*time.Second, flush)
|
||||
d.Trigger()
|
||||
|
||||
// 节流:每 2s 最多执行一次
|
||||
t := timer.NewThrottler(2*time.Second, alert)
|
||||
t.Trigger()
|
||||
```
|
||||
|
||||
### 5. 上下文超时监控 (Timeout Executor)
|
||||
结合打点追踪的超时执行器。
|
||||
|
||||
```go
|
||||
res, err := timer.RunTimeout(3*time.Second, func(tk *timer.Tracker) (any, error) {
|
||||
tk.Record("init")
|
||||
// ...
|
||||
return data, nil
|
||||
})
|
||||
```
|
||||
