# go-i18n ![Build status](https://github.com/nicksnyder/go-i18n/workflows/Build/badge.svg) [![Report card](https://goreportcard.com/badge/github.com/nicksnyder/go-i18n)](https://goreportcard.com/report/github.com/nicksnyder/go-i18n) [![codecov](https://codecov.io/gh/nicksnyder/go-i18n/branch/master/graph/badge.svg)](https://codecov.io/gh/nicksnyder/go-i18n) [![Sourcegraph](https://sourcegraph.com/github.com/nicksnyder/go-i18n/-/badge.svg)](https://sourcegraph.com/github.com/nicksnyder/go-i18n?badge) | ||

||
go-i18n 是一个帮助您将 Go 程序翻译成多种语言的 Go [包](#package-i18n) 和 [命令](#command-goi18n)。 | ||
|
||
- 支持 [Unicode Common Locale Data Repository (CLDR)](https://www.unicode.org/cldr/charts/28/supplemental/language_plural_rules.html) 中所有 200 多种语言的 [复数字符](https://cldr.unicode.org/index/cldr-spec/plural-rules)。 | ||
- 代码和测试是从 [CLDR 数据](https://cldr.unicode.org/index/downloads) 中 [自动生成](https://github.com/nicksnyder/go-i18n/tree/main/v2/internal/plural/codegen) 的。 | ||
- 使用 [text/template](https://golang.org/pkg/text/template/) 语法支持带有命名变量的字符串。 | ||
- 支持任何格式的消息文件(例如:JSON、TOML、YAML)。 | ||

## Package i18n | ||
|
||
[![GoDoc](https://godoc.org/github.com/nicksnyder/go-i18n?status.svg)](https://godoc.org/github.com/nicksnyder/go-i18n/v2/i18n) | ||
|
||
i18n 包支持根据一组语言环境首选项查找消息。 | ||
|
||
```go | ||
import "github.com/nicksnyder/go-i18n/v2/i18n" | ||
``` | ||
|
||
创建一个 Bundle 以在应用程序的整个生命周期中使用。 | ||
|
||
```go | ||
bundle := i18n.NewBundle(language.English) | ||
``` | ||
|
||
在初始化期间将翻译加载到您的 bundle 中。 | ||
|
||
```go | ||
bundle.RegisterUnmarshalFunc("toml", toml.Unmarshal) | ||
bundle.LoadMessageFile("es.toml") | ||
``` | ||
|
||
```go | ||
// 如果使用 go:embed | ||
//go:embed locale.*.toml | ||
var LocaleFS embed.FS | ||
|
||
bundle.RegisterUnmarshalFunc("toml", toml.Unmarshal) | ||
bundle.LoadMessageFileFS(LocaleFS, "locale.es.toml") | ||
``` | ||
|
||
创建一个 Localizer 以用于一组语言首选项。 | ||
|
||
```go | ||
func(w http.ResponseWriter, r *http.Request) { | ||
lang := r.FormValue("lang") | ||
accept := r.Header.Get("Accept-Language") | ||
localizer := i18n.NewLocalizer(bundle, lang, accept) | ||
} | ||
``` | ||
|
||
使用 Localizer 查找消息。 | ||
|
||
```go | ||
localizer.Localize(&i18n.LocalizeConfig{ | ||
DefaultMessage: &i18n.Message{ | ||
ID: "PersonCats", | ||
One: "{{.Name}} has {{.Count}} cat.", | ||
Other: "{{.Name}} has {{.Count}} cats.", | ||
}, | ||
TemplateData: map[string]interface{}{ | ||
"Name": "Nick", | ||
"Count": 2, | ||
}, | ||
PluralCount: 2, | ||
}) // Nick has 2 cats. | ||
``` | ||
|
||
## goi18n 命令 | ||
|
||
[![GoDoc](https://godoc.org/github.com/nicksnyder/go-i18n?status.svg)](https://godoc.org/github.com/nicksnyder/go-i18n/v2/goi18n) | ||
|
||
goi18n 命令管理 i18n 包使用的消息文件。 | ||
|
||
``` | ||
go get -u github.com/nicksnyder/go-i18n/v2/goi18n | ||
goi18n -help | ||
``` | ||
|
||
### 提取消息 | ||
|
||
使用 `goi18n extract` 将 Go 源文件中的所有 i18n.Message 结构文字提取到消息文件中以进行翻译。 | ||
|
||
```toml | ||
# active.en.toml | ||
[PersonCats] | ||
description = "The number of cats a person has" | ||
one = "{{.Name}} has {{.Count}} cat." | ||
other = "{{.Name}} has {{.Count}} cats." | ||
``` | ||
|
||
### 翻译一种新语言 | ||
|
||
1. 为您要添加的语言创建一个空消息文件(例如:`translate.es.toml`)。 | ||
2. 运行 `goi18n merge active.en.toml translate.es.toml` 以填充 `translate.es.toml` 要翻译的消息。 | ||
|
||
```toml | ||
# translate.es.toml | ||
[HelloPerson] | ||
hash = "sha1-5b49bfdad81fedaeefb224b0ffc2acc58b09cff5" | ||
other = "Hello {{.Name}}" | ||
``` | ||
|
||
3. 翻译完成 `translate.es.toml` 后,将其重命名为 `active.es.toml``。 | ||
|
||
```toml | ||
# active.es.toml | ||
[HelloPerson] | ||
hash = "sha1-5b49bfdad81fedaeefb224b0ffc2acc58b09cff5" | ||
other = "Hola {{.Name}}" | ||
``` | ||
|
||
4. 加载 `active.es.toml` 到您的 bundle 中。 | ||
|
||
```go | ||
bundle.RegisterUnmarshalFunc("toml", toml.Unmarshal) | ||
bundle.LoadMessageFile("active.es.toml") | ||
``` | ||
|
||
### 翻译新消息 | ||
|
||
如果您在程序中添加了新消息: | ||
|
||
1. 运行 `goi18n extract` 以使用新消息更新 `active.en.toml`。 | ||
2. 运行 `goi18n merge active.*.toml` 以生成更新的 `translate.*.toml` 文件。 | ||
3. 翻译 `translate.*.toml` 文件中的所有消息。 | ||
4. 运行 `goi18n merge active.*.toml translate.*.toml` 将翻译后的消息合并到 active 消息文件中。 | ||
|
