# 文档约定参考
|
||||
|
||||
## 参数和配置
|
||||
|
||||
> **建议**:记录容易出错或非显而易见的参数,而非所有参数。
|
||||
|
||||
```go
|
||||
// 不好:重复了显而易见的信息
|
||||
// Sprintf formats according to a format specifier and returns the resulting string.
|
||||
//
|
||||
// format is the format, and data is the interpolation data.
|
||||
func Sprintf(format string, data ...any) string
|
||||
|
||||
// 好:记录了非显而易见的行为
|
||||
// Sprintf formats according to a format specifier and returns the resulting string.
|
||||
//
|
||||
// The provided data is used to interpolate the format string. If the data does
|
||||
// not match the expected format verbs or the amount of data does not satisfy
|
||||
// the format specification, the function will inline warnings about formatting
|
||||
// errors into the output string.
|
||||
func Sprintf(format string, data ...any) string
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 上下文
|
||||
|
||||
> **建议**:不要重复隐含的上下文行为;记录例外情况。
|
||||
|
||||
上下文取消被隐含地认为会中断函数并返回 `ctx.Err()`。不要记录这一点。
|
||||
|
||||
```go
|
||||
// 不好:重复了隐含的行为
|
||||
// Run executes the worker's run loop.
|
||||
//
|
||||
// The method will process work until the context is cancelled.
|
||||
func (Worker) Run(ctx context.Context) error
|
||||
|
||||
// 好:只记录关键信息
|
||||
// Run executes the worker's run loop.
|
||||
func (Worker) Run(ctx context.Context) error
|
||||
```
|
||||
|
||||
**当行为不同时记录:**
|
||||
|
||||
```go
|
||||
// 好:非标准的取消行为
|
||||
// Run executes the worker's run loop.
|
||||
//
|
||||
// If the context is cancelled, Run returns a nil error.
|
||||
func (Worker) Run(ctx context.Context) error
|
||||
|
||||
// 好:特殊的上下文要求
|
||||
// NewReceiver starts receiving messages sent to the specified queue.
|
||||
// The context should not have a deadline.
|
||||
func NewReceiver(ctx context.Context) *Receiver
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 并发
|
||||
|
||||
> **建议**:记录非显而易见的线程安全特性。
|
||||
|
||||
只读操作被认为是安全的;修改操作被认为是不安全的。不要重复说明这一点。
|
||||
|
||||
**何时记录:**
|
||||
|
||||
```go
|
||||
// 不明确的操作(看似只读但内部有修改)
|
||||
// Lookup returns the data associated with the key from the cache.
|
||||
//
|
||||
// This operation is not safe for concurrent use.
|
||||
func (*Cache) Lookup(key string) (data []byte, ok bool)
|
||||
|
||||
// API 提供同步机制
|
||||
// NewFortuneTellerClient returns an *rpc.Client for the FortuneTeller service.
|
||||
// It is safe for simultaneous use by multiple goroutines.
|
||||
func NewFortuneTellerClient(cc *rpc.ClientConn) *FortuneTellerClient
|
||||
|
||||
// 接口有并发要求
|
||||
// A Watcher reports the health of some entity (usually a backend service).
|
||||
//
|
||||
// Watcher methods are safe for simultaneous use by multiple goroutines.
|
||||
type Watcher interface {
|
||||
Watch(changed chan<- bool) (unwatch func())
|
||||
Health() error
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 清理
|
||||
|
||||
> **建议**:始终记录显式清理要求。
|
||||
|
||||
```go
|
||||
// 好:
|
||||
// NewTicker returns a new Ticker containing a channel that will send the
|
||||
// current time on the channel after each tick.
|
||||
//
|
||||
// Call Stop to release the Ticker's associated resources when done.
|
||||
func NewTicker(d Duration) *Ticker
|
||||
|
||||
// 好:展示如何清理
|
||||
// Get issues a GET to the specified URL.
|
||||
//
|
||||
// When err is nil, resp always contains a non-nil resp.Body.
|
||||
// Caller should close resp.Body when done reading from it.
|
||||
//
|
||||
// resp, err := http.Get("http://example.com/")
|
||||
// if err != nil {
|
||||
// // handle error
|
||||
// }
|
||||
// defer resp.Body.Close()
|
||||
// body, err := io.ReadAll(resp.Body)
|
||||
func (c *Client) Get(url string) (resp *Response, err error)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 错误
|
||||
|
||||
> **建议**:记录重要的错误哨兵值和类型。
|
||||
|
||||
```go
|
||||
// 好:记录哨兵值
|
||||
// Read reads up to len(b) bytes from the File and stores them in b.
|
||||
//
|
||||
// At end of file, Read returns 0, io.EOF.
|
||||
func (*File) Read(b []byte) (n int, err error)
|
||||
|
||||
// 好:记录错误类型(包含指针接收者)
|
||||
// Chdir changes the current working directory to the named directory.
|
||||
//
|
||||
// If there is an error, it will be of type *PathError.
|
||||
func Chdir(dir string) error
|
||||
```
|
||||
|
||||
注意使用 `*PathError`(而非 `PathError`)可以确保 `errors.Is` 和 `errors.As` 的正确使用。
|
||||
|
||||
对于包级别的错误约定,在包注释中记录。
|
||||
|
||||

|
||||
|
||||
## 命名返回参数
|
||||
|
||||
> **建议**:在类型本身不够清晰时用于文档说明。
|
||||
|
||||
```go
|
||||
// 好:多个同类型参数
|
||||
func (n *Node) Children() (left, right *Node, err error)
|
||||
|
||||
// 好:面向操作的名称阐明了用法
|
||||
// The caller must arrange for the returned cancel function to be called.
|
||||
func WithTimeout(parent Context, d time.Duration) (ctx Context, cancel func())
|
||||
|
||||
// 不好:类型已经很清晰,命名没有增加信息
|
||||
func (n *Node) Parent1() (node *Node)
|
||||
func (n *Node) Parent2() (node *Node, err error)
|
||||
|
||||
// 好:类型已足够
|
||||
func (n *Node) Parent1() *Node
|
||||
func (n *Node) Parent2() (*Node, error)
|
||||
```
|
||||
|
||||
不要仅为启用裸返回而命名返回值。清晰性 > 简洁性。
|
||||

|
||||
|
||||
## 弃用通知
|
||||
|
||||
> **建议**:使用 `// Deprecated:` 注释标记符号为已弃用。
|
||||
|
||||
`Deprecated:` 段落必须出现在文档注释中紧接在符号之前。应说明使用什么替代。
|
||||
|
||||
**标准格式:**
|
||||
|
||||
```
|
||||
// Deprecated: Use NewThing instead.
|
||||
```
|
||||
|
||||
Godoc 会以特殊的视觉样式渲染 `Deprecated:` 注释,使其容易被发现。
|
||||
|
||||
**函数弃用:**
|
||||
|
||||
```go
|
||||
// EstimateSize returns an approximate byte count.
|
||||
//
|
||||
// Deprecated: Use [Size] instead, which returns an exact count.
|
||||
func EstimateSize(r io.Reader) (int64, error)
|
||||
```
|
||||
|
||||
**类型弃用:**
|
||||
|
||||
```go
|
||||
// LegacyClient talks to the v1 API.
|
||||
//
|
||||
// Deprecated: Use [Client] instead, which supports v2.
|
||||
type LegacyClient struct{ /* ... */ }
|
||||
```
|
||||
|
||||
**包弃用** — 在包文档注释中添加 `Deprecated:`:
|
||||
|
||||
```go
|
||||
// Package old provides the original implementation.
|
||||
//
|
||||
// Deprecated: Use package example/new instead.
|
||||
package old
|
||||
```
|
||||
|
||||
始终建议具体的替代方案,让调用者知道迁移目标。
|
||||

|
||||
## 注释语句 — 详细说明
|
||||
|
||||
> **规范**:文档注释必须是完整的句子。
|
||||
|
||||
- 首字母大写,以标点符号结尾
|
||||
- 例外:如果含义清晰,可以以小写标识符开头
|
||||
- 结构体字段的行尾注释可以是短语:
|
||||
|
||||
```go
|
||||
// 好:
|
||||
// A Server handles serving quotes from Shakespeare.
|
||||
type Server struct {
|
||||
// BaseDir points to the base directory for Shakespeare's works.
|
||||
//
|
||||
// Expected structure:
|
||||
// {BaseDir}/manifest.json
|
||||
// {BaseDir}/{name}/{name}-part{number}.txt
|
||||
BaseDir string
|
||||
|
||||
WelcomeMessage string // 用户登录时显示
|
||||
ProtocolVersion string // 与传入请求进行校验
|
||||
PageLength int // 每页行数(可选;默认值:20)
|
||||
}

# 包注释和示例参考
|
||||
|
||||
## 包注释
|
||||
|
||||
> **规范**:每个包必须有且仅有一个包注释。
|
||||
|
||||
```go
|
||||
// 好:
|
||||
// Package math provides basic constants and mathematical functions.
|
||||
//
|
||||
// This package does not guarantee bit-identical results across architectures.
|
||||
package math
|
||||
```
|
||||
|
||||
### Main 包
|
||||
|
||||
使用二进制名称(与 BUILD 文件匹配):
|
||||
|
||||
```go
|
||||
// 好:
|
||||
// The seed_generator command is a utility that generates a Finch seed file
|
||||
// from a set of JSON study configs.
|
||||
package main
|
||||
```
|
||||
|
||||
有效格式:`Binary seed_generator`、`Command seed_generator`、`The seed_generator command`、`Seed_generator ...`
|
||||
|
||||
### doc.go
|
||||
|
||||
- 对于较长的包注释,使用仅包含包注释和 `package` 声明的 `doc.go` 文件
|
||||
- 放在 import 之后的维护者注释不会出现在 Godoc 中
|
||||
- 保持 doc.go 文件专注于面向用户的文档
|
||||
|
||||
```go
|
||||
// Package complex provides advanced mathematical operations for
|
||||
// complex number arithmetic, including polar form conversion,
|
||||
// matrix operations, and numerical integration.
|
||||
//
|
||||
// Basic usage
|
||||
//
|
||||
// Create a complex number and perform operations:
|
||||
//
|
||||
// z := complex.New(3, 4)
|
||||
// magnitude := z.Abs() // 5.0
|
||||
// conjugate := z.Conj() // (3, -4)
|
||||
//
|
||||
// Matrix operations
|
||||
//
|
||||
// The package supports complex-valued matrices:
|
||||
//
|
||||
// m := complex.NewMatrix(2, 2)
|
||||
// m.Set(0, 0, complex.New(1, 0))
|
||||
// det := m.Det()
|
||||
package complex
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 可运行示例
|
||||
|
||||
> **建议**:提供可运行示例来展示包的用法。
|
||||
|
||||
将示例放在测试文件(`*_test.go`)中:
|
||||
|
||||
```go
|
||||
// 好:
|
||||
func ExampleConfig_WriteTo() {
|
||||
cfg := &Config{
|
||||
Name: "example",
|
||||
}
|
||||
if err := cfg.WriteTo(os.Stdout); err != nil {
|
||||
log.Exitf("Failed to write config: %s", err)
|
||||
}
|
||||
// Output:
|
||||
// {
|
||||
// "name": "example"
|
||||
// }
|
||||
}
|
||||
```
|
||||
|
||||
示例会出现在 Godoc 中,附加到对应的文档元素上。
|
||||
|
||||
### 命名约定
|
||||
|
||||
| 函数名称 | 文档对象 |
|
||||
|----------|---------|
|
||||
| `Example()` | 包级别示例 |
|
||||
| `ExampleFoo()` | 函数 `Foo` |
|
||||
| `ExampleBar_Baz()` | 方法 `Bar.Baz` |
|
||||
| `ExampleFoo_suffix()` | `Foo` 示例的命名变体 |
|
||||
|
||||
### 技巧
|
||||
|
||||
- 使用 `// Output:` 注释使示例可通过 `go test` 进行测试和验证
|
||||
- 保持示例专注于展示一个概念
|
||||
- 使用真实但精简的数据
|
||||
- 对于复杂的设置,使用 `testMain` 或辅助函数保持示例主体简洁
|
||||
- 同一符号的多个示例使用小写 `_suffix`:
|
||||
|
||||
```go
|
||||
func ExampleNewClient_withTimeout() {
|
||||
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
|
||||
defer cancel()
|
||||
client := NewClient(ctx)
|
||||
// ...

# Godoc 格式化参考
|
||||
|
||||
## Godoc 格式化
|
||||
|
||||
> **建议**:使用 godoc 语法编写格式良好的文档。
|
||||
|
||||
**段落** - 用空行分隔:
|
||||
|
||||
```go
|
||||
// 好:
|
||||
// LoadConfig reads a configuration out of the named file.
|
||||
//
|
||||
// See some/shortlink for config file format details.
|
||||
```
|
||||
|
||||
**逐字/代码块** - 额外缩进两个空格:
|
||||
|
||||
```go
|
||||
// 好:
|
||||
// Update runs the function in an atomic transaction.
|
||||
//
|
||||
// This is typically used with an anonymous TransactionFunc:
|
||||
//
|
||||
// if err := db.Update(func(state *State) { state.Foo = bar }); err != nil {
|
||||
// //...
|
||||
// }
|
||||
```
|
||||
|
||||
**列表和表格** - 使用逐字格式:
|
||||
|
||||
```go
|
||||
// 好:
|
||||
// LoadConfig treats the following keys in special ways:
|
||||
// "import" will make this configuration inherit from the named file.
|
||||
// "env" if present will be populated with the system environment.
|
||||
```
|
||||
|
||||
**标题** - 单行,首字母大写,无标点(括号/逗号除外),后跟段落:
|
||||
|
||||
```go
|
||||
// 好:
|
||||
// Using headings
|
||||
//
|
||||
// Headings come with autogenerated anchor tags for easy linking.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 信号增强
|
||||
|
||||
> **建议**:添加注释以突出不寻常或容易被忽略的模式。
|
||||
|
||||
以下两种情况很难区分:
|
||||
|
||||
```go
|
||||
if err := doSomething(); err != nil { // 常见
|
||||
// ...
|
||||
}
|
||||
|
||||
if err := doSomething(); err == nil { // 不寻常!
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
添加注释来增强信号:
|
||||
|
||||
```go
|
||||
// 好:
|
||||
if err := doSomething(); err == nil { // 如果没有错误
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 文档预览
|
||||
|
||||
> **建议**:在代码审查之前和期间预览文档。
|
||||
|
||||
```bash
|
||||
go install golang.org/x/pkgsite/cmd/pkgsite@latest
|
||||
pkgsite
|
||||
```
|
||||
|
||||
这可以验证 godoc 格式化是否正确渲染。
