Well, all roads lead to Rome. - -```go -type Child struct { - Age string -} - -type Parent struct { - Name string - Child `ini:"Parent"` -} +To use with latest changes: -type Config struct { - City string - Parent -} +```sh +$ go get github.com/go-ini/ini ``` -Example configuration: - -```ini -City = Boston - -[Parent] -Name = Unknwon -Age = 21 -``` +Please add `-u` flag to update in the future. ## Getting Help +- [Getting Started](https://ini.unknwon.io/docs/intro/getting_started) - [API Documentation](https://gowalker.org/gopkg.in/ini.v1) -- [File An Issue](https://github.com/go-ini/ini/issues/new) - -## FAQs - -### What does `BlockMode` field do? - -By default, library lets you read and write values so we need a locker to make sure your data is safe. But in cases that you are very sure about only reading data through the library, you can set `cfg.BlockMode = false` to speed up read operations about **50-70%** faster. - -### Why another INI library? - -Many people are using my another INI library [goconfig](https://github.com/Unknwon/goconfig), so the reason for this one is I would like to make more Go style code. Also when you set `cfg.BlockMode = false`, this one is about **10-30%** faster. - -To make those changes I have to confirm API broken, so it's safer to keep it in another place and start using `gopkg.in` to version my package at this time.(PS: shorter import path) ## License diff --git a/vendor/github.com/go-ini/ini/README_ZH.md b/vendor/github.com/go-ini/ini/README_ZH.md deleted file mode 100644 index 69aefef..0000000 --- a/vendor/github.com/go-ini/ini/README_ZH.md +++ /dev/null @@ -1,750 +0,0 @@ -本包提供了 Go 语言中读写 INI 文件的功能。 -

-这些键的值永远为 `true`，且在保存到文件时也只会输出键名。 - -如果您想要通过程序来生成此类键，则可以使用 `NewBooleanKey`： - -```go -key, err := sec.NewBooleanKey("skip-host-cache") -``` - -#### 关于注释 - -下述几种情况的内容将被视为注释： - -1. 所有以 `#` 或 `;` 开头的行 -2. 所有在 `#` 或 `;` 之后的内容 -3. 分区标签后的文字 (即 `[分区名]` 之后的内容) - -如果你希望使用包含 `#` 或 `;` 的值，请使用 ``` ` ``` 或 ``` """ ``` 进行包覆。 - -除此之外，您还可以通过 `LoadOptions` 完全忽略行内注释： - -```go -cfg, err := ini.LoadSources(ini.LoadOptions{IgnoreInlineComment: true}, "app.ini")) -``` - -### 操作分区（Section） - -获取指定分区： - -```go -section, err := cfg.GetSection("section name") -``` - -如果您想要获取默认分区，则可以用空字符串代替分区名： - -```go -section, err := cfg.GetSection("") -``` - -当您非常确定某个分区是存在的，可以使用以下简便方法： - -```go -section := cfg.Section("section name") -``` - -如果不小心判断错了，要获取的分区其实是不存在的，那会发生什么呢？没事的，它会自动创建并返回一个对应的分区对象给您。 - -创建一个分区： - -```go -err := cfg.NewSection("new section") -``` - -获取所有分区对象或名称： - -```go -sections := cfg.Sections() -names := cfg.SectionStrings() -``` - -### 操作键（Key） - -获取某个分区下的键： - -```go -key, err := cfg.Section("").GetKey("key name") -``` - -和分区一样，您也可以直接获取键而忽略错误处理： - -```go -key := cfg.Section("").Key("key name") -``` - -判断某个键是否存在： - -```go -yes := cfg.Section("").HasKey("key name") -``` - -创建一个新的键： - -```go -err := cfg.Section("").NewKey("name", "value") -``` - -获取分区下的所有键或键名： - -```go -keys := cfg.Section("").Keys() -names := cfg.Section("").KeyStrings() -``` - -获取分区下的所有键值对的克隆： - -```go -hash := cfg.Section("").KeysHash() -``` - -### 操作键值（Value） - -获取一个类型为字符串（string）的值： - -```go -val := cfg.Section("").Key("key name").String() -``` - -获取值的同时通过自定义函数进行处理验证： - -```go -val := cfg.Section("").Key("key name").Validate(func(in string) string { - if len(in) == 0 { - return "default" - } - return in -}) -``` - -如果您不需要任何对值的自动转变功能（例如递归读取），可以直接获取原值（这种方式性能最佳）： - -```go -val := cfg.Section("").Key("key name").Value() -``` - -判断某个原值是否存在： - -```go -yes := cfg.Section("").HasValue("test value") -``` - -获取其它类型的值： - -```go -// 布尔值的规则： -// true 当值为：1, t, T, TRUE, true, True, YES, yes, Yes, y, ON, on, On -// false 当值为：0, f, F, FALSE, false, False, NO, no, No, n, OFF, off, Off -v, err = cfg.Section("").Key("BOOL").Bool() -v, err = cfg.Section("").Key("FLOAT64").Float64() -v, err = cfg.Section("").Key("INT").Int() -v, err = cfg.Section("").Key("INT64").Int64() -v, err = cfg.Section("").Key("UINT").Uint() -v, err = cfg.Section("").Key("UINT64").Uint64() -v, err = cfg.Section("").Key("TIME").TimeFormat(time.RFC3339) -v, err = cfg.Section("").Key("TIME").Time() // RFC3339 -

-// 由 Must 开头的方法名允许接收一个相同类型的参数来作为默认值， -// 当键不存在或者转换失败时，则会直接返回该默认值。 -// 但是，MustString 方法必须传递一个默认值。 - -v = cfg.Seciont("").Key("String").MustString("default") -v = cfg.Section("").Key("BOOL").MustBool(true) -v = cfg.Section("").Key("FLOAT64").MustFloat64(1.25) -v = cfg.Section("").Key("INT").MustInt(10) -v = cfg.Section("").Key("INT64").MustInt64(99) -v = cfg.Section("").Key("UINT").MustUint(3) -v = cfg.Section("").Key("UINT64").MustUint64(6) -v = cfg.Section("").Key("TIME").MustTimeFormat(time.RFC3339, time.Now()) -v = cfg.Section("").Key("TIME").MustTime(time.Now()) // RFC3339 -``` - -如果我的值有好多行怎么办？ - -```ini -[advance] -ADDRESS = """404 road, -NotFound, State, 5000 -Earth""" -``` - -嗯哼？小 case！ - -```go -cfg.Section("advance").Key("ADDRESS").String() - -/* --- start --- -404 road, -NotFound, State, 5000 -Earth ------- end --- */ -``` - -赞爆了！那要是我属于一行的内容写不下想要写到第二行怎么办？ - -```ini -[advance] -two_lines = how about \ - continuation lines? -lots_of_lines = 1 \ - 2 \ - 3 \ - 4 -``` - -简直是小菜一碟！ - -```go -cfg.Section("advance").Key("two_lines").String() // how about continuation lines? -cfg.Section("advance").Key("lots_of_lines").String() // 1 2 3 4 -``` - -可是我有时候觉得两行连在一起特别没劲，怎么才能不自动连接两行呢？ - -```go -cfg, err := ini.LoadSources(ini.LoadOptions{ - IgnoreContinuation: true, -}, "filename") -``` - -哇靠给力啊！ - -需要注意的是，值两侧的单引号会被自动剔除： - -```ini -foo = "some value" // foo: some value -bar = 'some value' // bar: some value -``` - -有时您会获得像从 [Crowdin](https://crowdin.com/) 网站下载的文件那样具有特殊格式的值（值使用双引号括起来，内部的双引号被转义）： - -```ini -create_repo="创建了仓库 %s" -``` - -那么，怎么自动地将这类值进行处理呢？ - -```go -cfg, err := ini.LoadSources(ini.LoadOptions{UnescapeValueDoubleQuotes: true}, "en-US.ini")) -cfg.Section("").Key("create_repo").String() -// You got: 创建了仓库 %s -``` - -这就是全部了？哈哈，当然不是。 - -#### 操作键值的辅助方法 - -获取键值时设定候选值： - -```go -v = cfg.Section("").Key("STRING").In("default", []string{"str", "arr", "types"}) -v = cfg.Section("").Key("FLOAT64").InFloat64(1.1, []float64{1.25, 2.5, 3.75}) -v = cfg.Section("").Key("INT").InInt(5, []int{10, 20, 30}) -v = cfg.Section("").Key("INT64").InInt64(10, []int64{10, 20, 30}) -v = cfg.Section("").Key("UINT").InUint(4, []int{3, 6, 9}) -v = cfg.Section("").Key("UINT64").InUint64(8, []int64{3, 6, 9}) -v = cfg.Section("").Key("TIME").InTimeFormat(time.RFC3339, time.Now(), []time.Time{time1, time2, time3}) -v = cfg.Section("").Key("TIME").InTime(time.Now(), []time.Time{time1, time2, time3}) // RFC3339 -``` - -如果获取到的值不是候选值的任意一个，则会返回默认值，而默认值不需要是候选值中的一员。 - -验证获取的值是否在指定范围内： - -```go -vals = cfg.Section("").Key("FLOAT64").RangeFloat64(0.0, 1.1, 2.2) -vals = cfg.Section("").Key("INT").RangeInt(0, 10, 20) -vals = cfg.Section("").Key("INT64").RangeInt64(0, 10, 20) -vals = cfg.Section("").Key("UINT").RangeUint(0, 3, 9) -vals = cfg.Section("").Key("UINT64").RangeUint64(0, 3, 9) -vals = cfg.Section("").Key("TIME").RangeTimeFormat(time.RFC3339, time.Now(), minTime, maxTime) -vals = cfg.Section("").Key("TIME").RangeTime(time.Now(), minTime, maxTime) // RFC3339 -``` - -##### 自动分割键值到切片（slice） - -当存在无效输入时，使用零值代替： - -```go -// Input: 1.1, 2.2, 3.3, 4.4 -> [1.1 2.2 3.3 4.4] -// Input: how, 2.2, are, you -> [0.0 2.2 0.0 0.0] -vals = cfg.Section("").Key("STRINGS").Strings(",") -vals = cfg.Section("").Key("FLOAT64S").Float64s(",") -vals = cfg.Section("").Key("INTS").Ints(",") -vals = cfg.Section("").Key("INT64S").Int64s(",") -vals = cfg.Section("").Key("UINTS").Uints(",") -vals = cfg.Section("").Key("UINT64S").Uint64s(",") -vals = cfg.Section("").Key("TIMES").Times(",") -``` - -从结果切片中剔除无效输入： - -```go -// Input: 1.1, 2.2, 3.3, 4.4 -> [1.1 2.2 3.3 4.4] -// Input: how, 2.2, are, you -> [2.2] -vals = cfg.Section("").Key("FLOAT64S").ValidFloat64s(",") -vals = cfg.Section("").Key("INTS").ValidInts(",") -vals = cfg.Section("").Key("INT64S").ValidInt64s(",") -vals = cfg.Section("").Key("UINTS").ValidUints(",") -vals = cfg.Section("").Key("UINT64S").ValidUint64s(",") -vals = cfg.Section("").Key("TIMES").ValidTimes(",") -``` - -当存在无效输入时，直接返回错误： - -```go -// Input: 1.1, 2.2, 3.3, 4.4 -> [1.1 2.2 3.3 4.4] -// Input: how, 2.2, are, you -> error -vals = cfg.Section("").Key("FLOAT64S").StrictFloat64s(",") -vals = cfg.Section("").Key("INTS").StrictInts(",") -vals = cfg.Section("").Key("INT64S").StrictInt64s(",") -vals = cfg.Section("").Key("UINTS").StrictUints(",") -vals = cfg.Section("").Key("UINT64S").StrictUint64s(",") -vals = cfg.Section("").Key("TIMES").StrictTimes(",") -``` - -### 保存配置 - -终于到了这个时刻，是时候保存一下配置了。 - -比较原始的做法是输出配置到某个文件： - -```go -// ... -err = cfg.SaveTo("my.ini") -err = cfg.SaveToIndent("my.ini", "\t") -``` - -另一个比较高级的做法是写入到任何实现 `io.Writer` 接口的对象中： - -```go -// ... -cfg.WriteTo(writer) -cfg.WriteToIndent(writer, "\t") -``` - -默认情况下，空格将被用于对齐键值之间的等号以美化输出结果，以下代码可以禁用该功能： - -```go -ini.PrettyFormat = false -``` - -## 高级用法 - -### 递归读取键值 - -在获取所有键值的过程中，特殊语法 `%()s` 会被应用，其中 `` 可以是相同分区或者默认分区下的键名。字符串 `%()s` 会被相应的键值所替代，如果指定的键不存在，则会用空字符串替代。您可以最多使用 99 层的递归嵌套。 - -```ini -NAME = ini - -[author] -NAME = Unknwon -GITHUB = https://github.com/%(NAME)s - -[package] -FULL_NAME = github.com/go-ini/%(NAME)s -``` - -```go -cfg.Section("author").Key("GITHUB").String() // https://github.com/Unknwon -cfg.Section("package").Key("FULL_NAME").String() // github.com/go-ini/ini -``` - -### 读取父子分区 - -您可以在分区名称中使用 `.` 来表示两个或多个分区之间的父子关系。如果某个键在子分区中不存在，则会去它的父分区中再次寻找，直到没有父分区为止。 - -```ini -NAME = ini -VERSION = v1 -IMPORT_PATH = gopkg.in/%(NAME)s.%(VERSION)s - -[package] -CLONE_URL = https://%(IMPORT_PATH)s - -[package.sub] -``` - -```go -cfg.Section("package.sub").Key("CLONE_URL").String() // https://gopkg.in/ini.v1 -``` - -#### 获取上级父分区下的所有键名 - -```go -cfg.Section("package.sub").ParentKeys() // ["CLONE_URL"] -``` - -### 无法解析的分区 - -如果遇到一些比较特殊的分区，它们不包含常见的键值对，而是没有固定格式的纯文本，则可以使用 `LoadOptions.UnparsableSections` 进行处理： - -```go -cfg, err := LoadSources(ini.LoadOptions{UnparseableSections: []string{"COMMENTS"}}, `[COMMENTS] -<1> This slide has the fuel listed in the wrong units `)) - -body := cfg.Section("COMMENTS").Body() - -/* --- start --- -<1> This slide has the fuel listed in the wrong units ------- end --- */ -``` - -### 读取自增键名 - -如果数据源中的键名为 `-`，则认为该键使用了自增键名的特殊语法。计数器从 1 开始，并且分区之间是相互独立的。 - -```ini -[features] --: Support read/write comments of keys and sections --: Support auto-increment of key names --: Support load multiple files to overwrite key values -``` - -```go -cfg.Section("features").KeyStrings() // []{"#1", "#2", "#3"} -``` - -### 映射到结构 - -想要使用更加面向对象的方式玩转 INI 吗？好主意。 - -```ini -Name = Unknwon -age = 21 -Male = true -Born = 1993-01-01T20:17:05Z - -[Note] -Content = Hi is a good man! -Cities = HangZhou, Boston -``` - -```go -type Note struct { - Content string - Cities []string -} - -type Person struct { - Name string - Age int `ini:"age"` - Male bool - Born time.Time - Note - Created time.Time `ini:"-"` -} - -func main() { - cfg, err := ini.Load("path/to/ini") - // ... - p := new(Person) - err = cfg.MapTo(p) - // ... - - // 一切竟可以如此的简单。 - err = ini.MapTo(p, "path/to/ini") - // ... - - // 嗯哼？只需要映射一个分区吗？ - n := new(Note) - err = cfg.Section("Note").MapTo(n) - // ... -} -``` - -结构的字段怎么设置默认值呢？很简单，只要在映射之前对指定字段进行赋值就可以了。如果键未找到或者类型错误，该值不会发生改变。 - -```go -// ... -p := &Person{ - Name: "Joe", -} -// ... -``` - -这样玩 INI 真的好酷啊！然而，如果不能还给我原来的配置文件，有什么卵用？ - -### 从结构反射 - -可是，我有说不能吗？ - -```go -type Embeded struct { - Dates []time.Time `delim:"|" comment:"Time data"` - Places []string `ini:"places,omitempty"` - None []int `ini:",omitempty"` -} - -type Author struct { - Name string `ini:"NAME"` - Male bool - Age int `comment:"Author's age"` - GPA float64 - NeverMind string `ini:"-"` - *Embeded `comment:"Embeded section"` -} - -func main() { - a := &Author{"Unknwon", true, 21, 2.8, "", - &Embeded{ - []time.Time{time.Now(), time.Now()}, - []string{"HangZhou", "Boston"}, - []int{}, - }} - cfg := ini.Empty() - err = ini.ReflectFrom(cfg, a) - // ... -} -``` - -瞧瞧，奇迹发生了。 - -```ini -NAME = Unknwon -Male = true -; Author's age -Age = 21 -GPA = 2.8 - -; Embeded section -[Embeded] -; Time data -Dates = 2015-08-07T22:14:22+08:00|2015-08-07T22:14:22+08:00 -places = HangZhou,Boston -``` - -#### 名称映射器（Name Mapper） - -为了节省您的时间并简化代码，本库支持类型为 [`NameMapper`](https://gowalker.org/gopkg.in/ini.v1#NameMapper) 的名称映射器，该映射器负责结构字段名与分区名和键名之间的映射。 - -目前有 2 款内置的映射器： - -- `AllCapsUnderscore`：该映射器将字段名转换至格式 `ALL_CAPS_UNDERSCORE` 后再去匹配分区名和键名。 -- `TitleUnderscore`：该映射器将字段名转换至格式 `title_underscore` 后再去匹配分区名和键名。 - -使用方法： - -```go -type Info struct{ - PackageName string -} - -func main() { - err = ini.MapToWithMapper(&Info{}, ini.TitleUnderscore, []byte("package_name=ini")) - // ... - - cfg, err := ini.Load([]byte("PACKAGE_NAME=ini")) - // ... - info := new(Info) - cfg.NameMapper = ini.AllCapsUnderscore - err = cfg.MapTo(info) - // ... -} -``` - -使用函数 `ini.ReflectFromWithMapper` 时也可应用相同的规则。 - -#### 值映射器（Value Mapper） - -值映射器允许使用一个自定义函数自动展开值的具体内容，例如：运行时获取环境变量： - -```go -type Env struct { - Foo string `ini:"foo"` -} - -func main() { - cfg, err := ini.Load([]byte("[env]\nfoo = ${MY_VAR}\n") - cfg.ValueMapper = os.ExpandEnv - // ... - env := &Env{} - err = cfg.Section("env").MapTo(env) -} -``` - -本例中，`env.Foo` 将会是运行时所获取到环境变量 `MY_VAR` 的值。 - -#### 映射/反射的其它说明 - -任何嵌入的结构都会被默认认作一个不同的分区，并且不会自动产生所谓的父子分区关联： - -```go -type Child struct { - Age string -} - -type Parent struct { - Name string - Child -} - -type Config struct { - City string - Parent -} -``` - -示例配置文件： - -```ini -City = Boston - -[Parent] -Name = Unknwon - -[Child] -Age = 21 -``` - -很好，但是，我就是要嵌入结构也在同一个分区。好吧，你爹是李刚！ - -```go -type Child struct { - Age string -} - -type Parent struct { - Name string - Child `ini:"Parent"` -} - -type Config struct { - City string - Parent -} -``` - -示例配置文件： - -```ini -City = Boston - -[Parent] -Name = Unknwon -Age = 21 -``` - -## 获取帮助 - -- [API 文档](https://gowalker.org/gopkg.in/ini.v1) -- [创建工单](https://github.com/go-ini/ini/issues/new) - -## 常见问题 - -### 字段 `BlockMode` 是什么？ - -默认情况下，本库会在您进行读写操作时采用锁机制来确保数据时间。但在某些情况下，您非常确定只进行读操作。此时，您可以通过设置 `cfg.BlockMode = false` 来将读操作提升大约 **50-70%** 的性能。 - -### 为什么要写另一个 INI 解析库？ - -许多人都在使用我的 [goconfig](https://github.com/Unknwon/goconfig) 来完成对 INI 文件的操作，但我希望使用更加 Go 风格的代码。并且当您设置 `cfg.BlockMode = false` 时，会有大约 **10-30%** 的性能提升。 - -为了做出这些改变，我必须对 API 进行破坏，所以新开一个仓库是最安全的做法。除此之外，本库直接使用 `gopkg.in` 来进行版本化发布。（其实真相是导入路径更短了） diff --git a/vendor/github.com/go-ini/ini/file.go b/vendor/github.com/go-ini/ini/file.go new file mode 100644 index 0000000..d7982c3 --- /dev/null +++ b/vendor/github.com/go-ini/ini/file.go @@ -0,0 +1,407 @@ +// Copyright 2017 Unknwon +// +// Licensed under the Apache License, Version 2.0 (the "License"): you may +// not use this file except in compliance with the License.
