+
+Package ini provides INI file read and write functionality in Go.
+
+[简体中文](README_ZH.md)
+
+## Feature
+

+- Read with recursion values.
+- Read with parent-child sections.
+- Read with auto-increment key names.
+- Read with multiple-line values.
+- Read with tons of helper methods.
+- Read and convert values to Go types.
+- Read and **WRITE** comments of sections and keys.
+- Manipulate sections, keys and comments with ease.
+- Keep sections and keys in order as you parse and save.
+
+## Installation
+
+To use a tagged revision:
+
+	go get gopkg.in/ini.v1
+
+To use with latest changes:
+
+	go get github.com/go-ini/ini
+
+Please add `-u` flag to update in the future.
+
+### Testing
+
+If you want to test on your machine, please apply `-t` flag:
+
+	go get -t gopkg.in/ini.v1
+
+Please add `-u` flag to update in the future.
+
+## Getting Started
+
+### Loading from data sources
+
+A **Data Source** is either raw data in type `[]byte`, a file name with type `string` or `io.ReadCloser`. You can load **as many data sources as you want**. Passing other types will simply return an error.
+
+```go
+cfg, err := ini.Load([]byte("raw data"), "filename", ioutil.NopCloser(bytes.NewReader([]byte("some other data"))))
+```
+
+Or start with an empty object:
+
+```go
+cfg := ini.Empty()
+```
+
+When you cannot decide how many data sources to load at the beginning, you will still be able to **Append()** them later.
+
+```go
+err := cfg.Append("other file", []byte("other raw data"))
+```
+
+If you have a list of files with possibilities that some of them may not available at the time, and you don't know exactly which ones, you can use `LooseLoad` to ignore nonexistent files without returning error.
+
+```go
+cfg, err := ini.LooseLoad("filename", "filename_404")
+```
+
+The cool thing is, whenever the file is available to load while you're calling `Reload` method, it will be counted as usual.
+
+#### Ignore cases of key name
+
+When you do not care about cases of section and key names, you can use `InsensitiveLoad` to force all names to be lowercased while parsing.
+
+```go
+cfg, err := ini.InsensitiveLoad("filename")
+//...
+
+// sec1 and sec2 are the exactly same section object
+sec1, err := cfg.GetSection("Section")
+sec2, err := cfg.GetSection("SecTIOn")
+
+// key1 and key2 are the exactly same key object
+key1, err := sec1.GetKey("Key")
+key2, err := sec2.GetKey("KeY")
+```
+
+#### MySQL-like boolean key 
+
+MySQL's configuration allows a key without value as follows:
+
+```ini
+[mysqld]
+...
+skip-host-cache
+skip-name-resolve
+```
+
+By default, this is considered as missing value. But if you know you're going to deal with those cases, you can assign advanced load options:
+
+```go
+cfg, err := ini.LoadSources(ini.LoadOptions{AllowBooleanKeys: true}, "my.cnf"))
+```
+
+The value of those keys are always `true`, and when you save to a file, it will keep in the same foramt as you read.
+
+To generate such keys in your program, you could use `NewBooleanKey`:
+
+```go
+key, err := sec.NewBooleanKey("skip-host-cache")
+```
+
+#### Comment
+
+Take care that following format will be treated as comment:
+
+1. Line begins with `#` or `;`
+2. Words after `#` or `;`
+3. Words after section name (i.e words after `[some section name]`)
+
+If you want to save a value with `#` or `;`, please quote them with ``` ` ``` or ``` """ ```.
+
+Alternatively, you can use following `LoadOptions` to completely ignore inline comments:
+
+```go
+cfg, err := ini.LoadSources(ini.LoadOptions{IgnoreInlineComment: true}, "app.ini"))
+```
+
+### Working with sections
+
+To get a section, you would need to:
+
+```go
+section, err := cfg.GetSection("section name")
+```
+
+For a shortcut for default section, just give an empty string as name:
+
+```go
+section, err := cfg.GetSection("")
+```
+
+When you're pretty sure the section exists, following code could make your life easier:
+
+```go
+section := cfg.Section("section name")
+```
+
+What happens when the section somehow does not exist? Don't panic, it automatically creates and returns a new section to you.
+
+To create a new section:
+
+```go
+err := cfg.NewSection("new section")
+```
+
+To get a list of sections or section names:
+
+```go
+sections := cfg.Sections()
+names := cfg.SectionStrings()
+```
+
+### Working with keys
+
+To get a key under a section:
+
+```go
+key, err := cfg.Section("").GetKey("key name")
+```
+
+Same rule applies to key operations:
+
+```go
+key := cfg.Section("").Key("key name")
+```
+
+To check if a key exists:
+
+```go
+yes := cfg.Section("").HasKey("key name")
+```
+
+To create a new key:
+
+```go
+err := cfg.Section("").NewKey("name", "value")
+```
+
+To get a list of keys or key names:
+
+```go
+keys := cfg.Section("").Keys()
+names := cfg.Section("").KeyStrings()
+```
+
+To get a clone hash of keys and corresponding values:
+
+```go
+hash := cfg.Section("").KeysHash()
+```
+
+### Working with values
+
+To get a string value:
+
+```go
+val := cfg.Section("").Key("key name").String()
+```
+
+To validate key value on the fly:
+
+```go
+val := cfg.Section("").Key("key name").Validate(func(in string) string {
+	if len(in) == 0 {
+		return "default"
+	}
+	return in
+})
+```
+
+If you do not want any auto-transformation (such as recursive read) for the values, you can get raw value directly (this way you get much better performance):
+
+```go
+val := cfg.Section("").Key("key name").Value()
+```
+
+To check if raw value exists:
+
+```go
+yes := cfg.Section("").HasValue("test value")
+```
+
+To get value with types:
+
+```go
+// For boolean values:
+// true when value is: 1, t, T, TRUE, true, True, YES, yes, Yes, y, ON, on, On
+// false when value is: 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
+
+v = cfg.Section("").Key("BOOL").MustBool()
+v = cfg.Section("").Key("FLOAT64").MustFloat64()
+v = cfg.Section("").Key("INT").MustInt()
+v = cfg.Section("").Key("INT64").MustInt64()
+v = cfg.Section("").Key("UINT").MustUint()
+v = cfg.Section("").Key("UINT64").MustUint64()
+v = cfg.Section("").Key("TIME").MustTimeFormat(time.RFC3339)
+v = cfg.Section("").Key("TIME").MustTime() // RFC3339
+
+// Methods start with Must also accept one argument for default value
+// when key not found or fail to parse value to given type.
+// Except method MustString, which you have to pass a default value.
+
+v = cfg.Section("").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
+```
+
+What if my value is three-line long?
+
+```ini
+[advance]
+ADDRESS = """404 road,
+NotFound, State, 5000
+Earth"""
+```
+
+Not a problem!
+
+```go
+cfg.Section("advance").Key("ADDRESS").String()
+
+/* --- start ---
+404 road,
+NotFound, State, 5000
+Earth
+------  end  --- */
+```
+
+That's cool, how about continuation lines?
+
+```ini
+[advance]
+two_lines = how about \
+	continuation lines?
+lots_of_lines = 1 \
+	2 \
+	3 \
+	4
+```
+
+Piece of cake!
+
+```go
+cfg.Section("advance").Key("two_lines").String() // how about continuation lines?
+cfg.Section("advance").Key("lots_of_lines").String() // 1 2 3 4
+```
+
+Well, I hate continuation lines, how do I disable that?
+
+```go
+cfg, err := ini.LoadSources(ini.LoadOptions{
+	IgnoreContinuation: true,
+}, "filename")
+```
+
+Holy crap! 
+
+Note that single quotes around values will be stripped:
+
+```ini
+foo = "some value" // foo: some value
+bar = 'some value' // bar: some value
+```
+
+Sometimes you downloaded file from [Crowdin](https://crowdin.com/) has values like the following (value is surrounded by double quotes and quotes in the value are escaped):
+
+```ini
+create_repo="created repository <a href=\"%s\">%s</a>"
+```
+
+How do you transform this to regular format automatically?
+
+```go
+cfg, err := ini.LoadSources(ini.LoadOptions{UnescapeValueDoubleQuotes: true}, "en-US.ini"))
+cfg.Section("<name of your section>").Key("create_repo").String() 
+// You got: created repository <a href="%s">%s</a>
+```
+
+That's all? Hmm, no.
+
+#### Helper methods of working with values
+
+To get value with given candidates:
+
+```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
+```
+
+Default value will be presented if value of key is not in candidates you given, and default value does not need be one of candidates.
+
+To validate value in a given range:
+
+```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
+```
+
+##### Auto-split values into a slice
+
+To use zero value of type for invalid inputs:
+
+```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(",")
+```
+
+To exclude invalid values out of result slice:
+
+```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(",")
+```
+
+Or to return nothing but error when have invalid inputs:
+
+```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(",")
+```
+
+### Save your configuration
+
+Finally, it's time to save your configuration to somewhere.
+
+A typical way to save configuration is writing it to a file:
+
+```go
+// ...
+err = cfg.SaveTo("my.ini")
+err = cfg.SaveToIndent("my.ini", "\t")
+```
+
+Another way to save is writing to a `io.Writer` interface:
+
+```go
+// ...
+cfg.WriteTo(writer)
+cfg.WriteToIndent(writer, "\t")
+```
+
+By default, spaces are used to align "=" sign between key and values, to disable that:
+
+```go
+ini.PrettyFormat = false
+``` 
+
+## Advanced Usage
+
+### Recursive Values
+
+For all value of keys, there is a special syntax `%(<name>)s`, where `<name>` is the key name in same section or default section, and `%(<name>)s` will be replaced by corresponding value(empty string if key not found). You can use this syntax at most 99 level of recursions.
+
+```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
+```
+
+### Parent-child Sections
+
+You can use `.` in section name to indicate parent-child relationship between two or more sections. If the key not found in the child section, library will try again on its parent section until there is no parent section.
+
+```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
+```
+
+#### Retrieve parent keys available to a child section
+
+```go
+cfg.Section("package.sub").ParentKeys() // ["CLONE_URL"]
+```
+
+### Unparseable Sections
+
+Sometimes, you have sections that do not contain key-value pairs but raw content, to handle such case, you can use `LoadOptions.UnparsableSections`:
+
+```go
+cfg, err := ini.LoadSources(ini.LoadOptions{UnparseableSections: []string{"COMMENTS"}}, `[COMMENTS]
+<1><L.Slide#2> This slide has the fuel listed in the wrong units <e.1>`))
+
+body := cfg.Section("COMMENTS").Body()
+
+/* --- start ---
+<1><L.Slide#2> This slide has the fuel listed in the wrong units <e.1>
+------  end  --- */
+```
+
+### Auto-increment Key Names
+
+If key name is `-` in data source, then it would be seen as special syntax for auto-increment key name start from 1, and every section is independent on counter.
+
+```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"}
+```
+
+### Map To Struct
+
+Want more objective way to play with INI? Cool.
+
+```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)
+	// ...
+
+	// Things can be simpler.
+	err = ini.MapTo(p, "path/to/ini")
+	// ...
+
+	// Just map a section? Fine.
+	n := new(Note)
+	err = cfg.Section("Note").MapTo(n)
+	// ...
+}
+```
+
+Can I have default value for field? Absolutely.
+
+Assign it before you map to struct. It will keep the value as it is if the key is not presented or got wrong type.
+
+```go
+// ...
+p := &Person{
+	Name: "Joe",
+}
+// ...
+```
+
+It's really cool, but what's the point if you can't give me my file back from struct?
+
+### Reflect From Struct
+
+Why not?
+
+```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)
+	// ...
+}
+```
+
+So, what do I get?
+
+```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
+```
+
+#### Name Mapper
+
+To save your time and make your code cleaner, this library supports [`NameMapper`](https://gowalker.org/gopkg.in/ini.v1#NameMapper) between struct field and actual section and key name.
+
+There are 2 built-in name mappers:
+
+- `AllCapsUnderscore`: it converts to format `ALL_CAPS_UNDERSCORE` then match section or key.
+- `TitleUnderscore`: it converts to format `title_underscore` then match section or key.
+
+To use them:
+
+```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)
+	// ...
+}
+```
+
+Same rules of name mapper apply to `ini.ReflectFromWithMapper` function.
+
+#### Value Mapper
+
+To expand values (e.g. from environment variables), you can use the `ValueMapper` to transform values:
+
+```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)
+}
+```
+
+This would set the value of `env.Foo` to the value of the environment variable `MY_VAR`.
+
+#### Other Notes On Map/Reflect
+
+Any embedded struct is treated as a section by default, and there is no automatic parent-child relations in map/reflect feature:
+
+```go
+type Child struct {
+	Age string
+}
+
+type Parent struct {
+	Name string
+	Child
+}
+
+type Config struct {
+	City string
+	Parent
+}
+```
+
+Example configuration:
+
+```ini
+City = Boston
+
+[Parent]
+Name = Unknwon
+
+[Child]
+Age = 21
+```
+
+What if, yes, I'm paranoid, I want embedded struct to be in the same section. Well, all roads lead to Rome.
+
+```go
+type Child struct {
+	Age string
+}
+
+type Parent struct {
+	Name string
+	Child `ini:"Parent"`
+}
+
+type Config struct {
+	City string
+	Parent
+}
+```
+
+Example configuration:
+
+```ini
+City = Boston
+
+[Parent]
+Name = Unknwon
+Age = 21
+```

+
+## 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)

+## 下载安装
+
+使用一个特定版本：
+
+    go get gopkg.in/ini.v1
+
+使用最新版：
+
+	go get github.com/go-ini/ini
+
+如需更新请添加 `-u` 选项。
+
+### 测试安装
+
+如果您想要在自己的机器上运行测试，请使用 `-t` 标记：
+
+	go get -t gopkg.in/ini.v1
+
+如需更新请添加 `-u` 选项。
+
+## 开始使用
+
+### 从数据源加载
+
+一个 **数据源** 可以是 `[]byte` 类型的原始数据，`string` 类型的文件路径或 `io.ReadCloser`。您可以加载 **任意多个** 数据源。如果您传递其它类型的数据源，则会直接返回错误。
+
+```go
+cfg, err := ini.Load([]byte("raw data"), "filename", ioutil.NopCloser(bytes.NewReader([]byte("some other data"))))
+```
+
+或者从一个空白的文件开始：
+
+```go
+cfg := ini.Empty()
+```
+
+当您在一开始无法决定需要加载哪些数据源时，仍可以使用 **Append()** 在需要的时候加载它们。
+
+```go
+err := cfg.Append("other file", []byte("other raw data"))
+```
+
+当您想要加载一系列文件，但是不能够确定其中哪些文件是不存在的，可以通过调用函数 `LooseLoad` 来忽略它们（`Load` 会因为文件不存在而返回错误）：
+
+```go
+cfg, err := ini.LooseLoad("filename", "filename_404")
+```
+
+更牛逼的是，当那些之前不存在的文件在重新调用 `Reload` 方法的时候突然出现了，那么它们会被正常加载。
+
+#### 忽略键名的大小写
+
+有时候分区和键的名称大小写混合非常烦人，这个时候就可以通过 `InsensitiveLoad` 将所有分区和键名在读取里强制转换为小写：
+
+```go
+cfg, err := ini.InsensitiveLoad("filename")
+//...
+
+// sec1 和 sec2 指向同一个分区对象
+sec1, err := cfg.GetSection("Section")
+sec2, err := cfg.GetSection("SecTIOn")
+
+// key1 和 key2 指向同一个键对象
+key1, err := sec1.GetKey("Key")
+key2, err := sec2.GetKey("KeY")
+```
+
+#### 类似 MySQL 配置中的布尔值键
+
+MySQL 的配置文件中会出现没有具体值的布尔类型的键：
+
+```ini
+[mysqld]
+...
+skip-host-cache
+skip-name-resolve
+```
+
+默认情况下这被认为是缺失值而无法完成解析，但可以通过高级的加载选项对它们进行处理：
+
+```go
+cfg, err := ini.LoadSources(ini.LoadOptions{AllowBooleanKeys: true}, "my.cnf"))
+```
+
+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
+
+v = cfg.Section("").Key("BOOL").MustBool()
+v = cfg.Section("").Key("FLOAT64").MustFloat64()
+v = cfg.Section("").Key("INT").MustInt()
+v = cfg.Section("").Key("INT64").MustInt64()
+v = cfg.Section("").Key("UINT").MustUint()
+v = cfg.Section("").Key("UINT64").MustUint64()
+v = cfg.Section("").Key("TIME").MustTimeFormat(time.RFC3339)
+v = cfg.Section("").Key("TIME").MustTime() // 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 <a href=\"%s\">%s</a>"
+```
+
+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("<name of your section>").Key("create_repo").String() 
+// You got: 创建了仓库 <a href="%s">%s</a>
+```
+
+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 `%(<name>)s` 会被应用，其中 `<name>` 可以是相同分区或者默认分区下的键名。字符串 `%(<name>)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><L.Slide#2> This slide has the fuel listed in the wrong units <e.1>`))
+
+body := cfg.Section("COMMENTS").Body()
+
+/* --- start ---
+<1><L.Slide#2> This slide has the fuel listed in the wrong units <e.1>
+------  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
+```

+## 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）

+Go CSV
+=====
+
+The GoCSV package aims to provide easy serialization and deserialization functions to use CSV in Golang
+
+API and techniques inspired from https://godoc.org/gopkg.in/mgo.v2
+
+[![GoDoc](https://godoc.org/github.com/gocarina/gocsv?status.png)](https://godoc.org/github.com/gocarina/gocsv)
+[![Build Status](https://travis-ci.org/gocarina/gocsv.svg?branch=master)](https://travis-ci.org/gocarina/gocsv)
+
+Installation
+=====
+
+```go get -u github.com/gocarina/gocsv```
+
+Full example
+=====
+
+Consider the following CSV file
+
+```csv
+
+client_id,client_name,client_age
+1,Jose,42
+2,Daniel,26
+3,Vincent,32
+
+```
+
+Easy binding in Go!
+---
+
+```go
+
+package main
+
+import (
+	"fmt"
+	"gocsv"
+	"os"
+)
+
+type Client struct { // Our example struct, you can use "-" to ignore a field
+	Id      string `csv:"client_id"`
+	Name    string `csv:"client_name"`
+	Age     string `csv:"client_age"`
+	NotUsed string `csv:"-"`
+}
+
+func main() {
+	clientsFile, err := os.OpenFile("clients.csv", os.O_RDWR|os.O_CREATE, os.ModePerm)
+	if err != nil {
+		panic(err)
+	}
+	defer clientsFile.Close()
+
+	clients := []*Client{}
+
+	if err := gocsv.UnmarshalFile(clientsFile, &clients); err != nil { // Load clients from file
+		panic(err)
+	}
+	for _, client := range clients {
+		fmt.Println("Hello", client.Name)
+	}
+
+	if _, err := clientsFile.Seek(0, 0); err != nil { // Go to the start of the file
+		panic(err)
+	}
+
+	clients = append(clients, &Client{Id: "12", Name: "John", Age: "21"}) // Add clients
+	clients = append(clients, &Client{Id: "13", Name: "Fred"})
+	clients = append(clients, &Client{Id: "14", Name: "James", Age: "32"})
+	clients = append(clients, &Client{Id: "15", Name: "Danny"})
+	csvContent, err := gocsv.MarshalString(&clients) // Get all clients as CSV string
+	//err = gocsv.MarshalFile(&clients, clientsFile) // Use this to save the CSV back to the file
+	if err != nil {
+		panic(err)
+	}
+	fmt.Println(csvContent) // Display all clients as CSV string
+
+}
+
+```
+
+Customizable Converters
+---
+
+```go
+
+type DateTime struct {
+	time.Time
+}
+
+// Convert the internal date as CSV string
+func (date *DateTime) MarshalCSV() (string, error) {
+	return date.Time.Format("20060201"), nil
+}
+
+// You could also use the standard Stringer interface 
+func (date *DateTime) String() (string) {
+	return date.String() // Redundant, just for example
+}
+
+// Convert the CSV string as internal date
+func (date *DateTime) UnmarshalCSV(csv string) (err error) {
+	date.Time, err = time.Parse("20060201", csv)
+	if err != nil {
+		return err
+	}
+	return nil
+}
+
+type Client struct { // Our example struct with a custom type (DateTime)
+	Id       string   `csv:"id"`
+	Name     string   `csv:"name"`
+	Employed DateTime `csv:"employed"`
+}
+
+```
+
+Customizable CSV Reader / Writer
+---
+
+```go
+
+func main() {
+        ...
+	
+        gocsv.SetCSVReader(func(in io.Reader) gocsv.CSVReader {
+            r := csv.NewReader(in)

+            r.LazyQuotes = true
+            r.Comma = '.'
+            return r // Allows use dot as delimiter and use quotes in CSV
+        })
+	
+        ...
+	
+        gocsv.SetCSVReader(func(in io.Reader) gocsv.CSVReader {
+            //return csv.NewReader(in)

+[![Build Status](https://travis-ci.org/ogier/pflag.png?branch=master)](https://travis-ci.org/ogier/pflag)
+
+## Description
+
+pflag is a drop-in replacement for Go's flag package, implementing
+POSIX/GNU-style --flags.
+
+pflag is compatible with the [GNU extensions to the POSIX recommendations
+for command-line options][1]. For a more precise description, see the
+"Command-line flag syntax" section below.
+
+[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+pflag is available under the same style of BSD license as the Go language,
+which can be found in the LICENSE file.
+
+## Installation
+
+pflag is available using the standard `go get` command.
+
+Install by running:
+
+    go get github.com/ogier/pflag
+
+Run tests by running:
+
+    go test github.com/ogier/pflag
+
+## Usage
+
+pflag is a drop-in replacement of Go's native flag package. If you import
+pflag under the name "flag" then all code should continue to function
+with no changes.
+
+``` go
+import flag "github.com/ogier/pflag"
+```
+
+There is one exception to this: if you directly instantiate the Flag struct
+there is one more field "Shorthand" that you will need to set.
+Most code never instantiates this struct directly, and instead uses
+functions such as String(), BoolVar(), and Var(), and is therefore
+unaffected.
+
+Define flags using flag.String(), Bool(), Int(), etc.
+
+This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+
+``` go
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+```
+
+If you like, you can bind the flag to a variable using the Var() functions.
+
+``` go
+var flagvar int
+func init() {
+    flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+}
+```
+
+Or you can create custom flags that satisfy the Value interface (with
+pointer receivers) and couple them to flag parsing by
+
+``` go
+flag.Var(&flagVal, "name", "help message for flagname")
+```
+
+For such flags, the default value is just the initial value of the variable.
+
+After all flags are defined, call
+
+``` go
+flag.Parse()
+```
+
+to parse the command line into the defined flags.
+
+Flags may then be used directly. If you're using the flags themselves,
+they are all pointers; if you bind to variables, they're values.
+
+``` go
+fmt.Println("ip has value ", *ip)
+fmt.Println("flagvar has value ", flagvar)
+```
+
+After parsing, the arguments after the flag are available as the
+slice flag.Args() or individually as flag.Arg(i).
+The arguments are indexed from 0 through flag.NArg()-1.
+
+The pflag package also defines some new functions that are not in flag,
+that give one-letter shorthands for flags. You can use these by appending
+'P' to the name of any function that defines a flag.
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+var flagvar bool
+func init() {
+    flag.BoolVarP("boolname", "b", true, "help message")
+}
+flag.VarP(&flagVar, "varname", "v", 1234, "help message")
+```
+
+Shorthand letters can be used with single dashes on the command line.
+Boolean shorthand flags can be combined with other shorthand flags.
+
+The default set of command-line flags is controlled by
+top-level functions.  The FlagSet type allows one to define
+independent sets of flags, such as to implement subcommands
+in a command-line interface. The methods of FlagSet are
+analogous to the top-level functions for the command-line
+flag set.
+
+## Command line flag syntax
+
+```
+--flag    // boolean flags only
+--flag=x
+```
+
+Unlike the flag package, a single dash before an option means something
+different than a double dash. Single dashes signify a series of shorthand
+letters for flags. All but the last shorthand letter must be boolean flags.
+
+```
+// boolean flags
+-f
+-abc
+
+// non-boolean flags
+-n 1234
+-Ifile
+
+// mixed
+-abcs "hello"
+-abcn1234
+```
+
+Flag parsing stops after the terminator "--". Unlike the flag package,
+flags can be interspersed with arguments anywhere on the command line
+before this terminator.
+
+Integer flags accept 1234, 0664, 0x1234 and may be negative.
+Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+TRUE, FALSE, True, False.
+Duration flags accept any input valid for time.ParseDuration.
+
+## More info
+
+You can see the full reference documentation of the pflag package
+[at godoc.org][3], or through go's standard documentation system by
+running `godoc -http=:6060` and browsing to
+[http://localhost:6060/pkg/github.com/ogier/pflag][2] after
+installation.

+	pflag under the name "flag" then all code should continue to function
+	with no changes.
+
+		import flag "github.com/ogier/pflag"
+
+	There is one exception to this: if you directly instantiate the Flag struct
+	there is one more field "Shorthand" that you will need to set.
+	Most code never instantiates this struct directly, and instead uses
+	functions such as String(), BoolVar(), and Var(), and is therefore
+	unaffected.
+
+	Define flags using flag.String(), Bool(), Int(), etc.
+
+	This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+		var ip = flag.Int("flagname", 1234, "help message for flagname")
+	If you like, you can bind the flag to a variable using the Var() functions.
+		var flagvar int
+		func init() {
+			flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+		}
+	Or you can create custom flags that satisfy the Value interface (with
+	pointer receivers) and couple them to flag parsing by
+		flag.Var(&flagVal, "name", "help message for flagname")
+	For such flags, the default value is just the initial value of the variable.
+
+	After all flags are defined, call
+		flag.Parse()
+	to parse the command line into the defined flags.
+
+	Flags may then be used directly. If you're using the flags themselves,
+	they are all pointers; if you bind to variables, they're values.
+		fmt.Println("ip has value ", *ip)
+		fmt.Println("flagvar has value ", flagvar)
+
+	After parsing, the arguments after the flag are available as the
+	slice flag.Args() or individually as flag.Arg(i).
+	The arguments are indexed from 0 through flag.NArg()-1.
+
+	The pflag package also defines some new functions that are not in flag,
+	that give one-letter shorthands for flags. You can use these by appending
+	'P' to the name of any function that defines a flag.
+		var ip = flag.IntP("flagname", "f", 1234, "help message")
+		var flagvar bool
+		func init() {
+			flag.BoolVarP("boolname", "b", true, "help message")
+		}
+		flag.VarP(&flagVar, "varname", "v", 1234, "help message")
+	Shorthand letters can be used with single dashes on the command line.
+	Boolean shorthand flags can be combined with other shorthand flags.
+
+	Command line flag syntax:
+		--flag    // boolean flags only
+		--flag=x
+
+	Unlike the flag package, a single dash before an option means something
+	different than a double dash. Single dashes signify a series of shorthand
+	letters for flags. All but the last shorthand letter must be boolean flags.
+		// boolean flags
+		-f
+		-abc
+		// non-boolean flags
+		-n 1234
+		-Ifile
+		// mixed
+		-abcs "hello"
+		-abcn1234
+
+	Flag parsing stops after the terminator "--". Unlike the flag package,
+	flags can be interspersed with arguments anywhere on the command line
+	before this terminator.
+
+	Integer flags accept 1234, 0664, 0x1234 and may be negative.
+	Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+	TRUE, FALSE, True, False.
+	Duration flags accept any input valid for time.ParseDuration.
+
+	The default set of command-line flags is controlled by
+	top-level functions.  The FlagSet type allows one to define
+	independent sets of flags, such as to implement subcommands
+	in a command-line interface. The methods of FlagSet are
+	analogous to the top-level functions for the command-line
+	flag set.
