// Package redis is a client for the Redis database.
//
// The Redigo FAQ (https://github.com/garyburd/redigo/wiki/FAQ) contains more
// documentation about this package.
//
// Connections
//
// The Conn interface is the primary interface for working with Redis.
// Applications create connections by calling the Dial, DialWithTimeout or
// NewConn functions. In the future, functions will be added for creating
// sharded and other types of connections.
//
// The application must call the connection Close method when the application
// is done with the connection.
//
// Executing Commands
//
// The Conn interface has a generic method for executing Redis commands:
//
// Do(commandName string, args ...interface{}) (reply interface{}, err error)
//
// The Redis command reference (http://redis.io/commands) lists the available
// commands. An example of using the Redis APPEND command is:
//
// n, err := conn.Do("APPEND", "key", "value")
//
// The Do method converts command arguments to bulk strings for transmission
// to the server as follows:
//
// Go Type Conversion
// []byte Sent as is
// string Sent as is
// int, int64 strconv.FormatInt(v)
// float64 strconv.FormatFloat(v, 'g', -1, 64)
// bool true -> "1", false -> "0"
// nil ""
// all other types fmt.Fprint(w, v)
//
// Redis command reply types are represented using the following Go types:
//
// Redis type Go type
// error redis.Error
// integer int64
// simple string string
// bulk string []byte or nil if value not present.
// array []interface{} or nil if value not present.
//
// Use type assertions or the reply helper functions to convert from
// interface{} to the specific Go type for the command result.
//
// Pipelining
//
// Connections support pipelining using the Send, Flush and Receive methods.
//
// Send(commandName string, args ...interface{}) error
// Flush() error
// Receive() (reply interface{}, err error)
//
// Send writes the command to the connection's output buffer. Flush flushes the
// connection's output buffer to the server. Receive reads a single reply from
// the server. The following example shows a simple pipeline.
//
// c.Send("SET", "foo", "bar")
// c.Send("GET", "foo")
// c.Flush()
// c.Receive() // reply from SET
// v, err = c.Receive() // reply from GET
//
// The Do method combines the functionality of the Send, Flush and Receive
// methods. The Do method starts by writing the command and flushing the output
// buffer. Next, the Do method receives all pending replies including the reply
// for the command just sent by Do. If any of the received replies is an error,
// then Do returns the error. If there are no errors, then Do returns the last
// reply. If the command argument to the Do method is "", then the Do method
// will flush the output buffer and receive pending replies without sending a
// command.
//
// Use the Send and Do methods to implement pipelined transactions.
//
// c.Send("MULTI")
// c.Send("INCR", "foo")
// c.Send("INCR", "bar")
// r, err := c.Do("EXEC")
// fmt.Println(r) // prints [1, 1]
//
// Concurrency
//
// Connections support one concurrent caller to the Receive method and one
// concurrent caller to the Send and Flush methods. No other concurrency is
// supported including concurrent calls to the Do method.
//
// For full concurrent access to Redis, use the thread-safe Pool to get, use
// and release a connection from within a goroutine. Connections returned from
// a Pool have the concurrency restrictions described in the previous
// paragraph.
//
// Publish and Subscribe
//
// Use the Send, Flush and Receive methods to implement Pub/Sub subscribers.
//
// c.Send("SUBSCRIBE", "example")
// c.Flush()
// for {
// reply, err := c.Receive()
// if err != nil {
// return err
// }
// // process pushed message
// }
//
// The PubSubConn type wraps a Conn with convenience methods for implementing
// subscribers. The Subscribe, PSubscribe, Unsubscribe and PUnsubscribe methods
// send and flush a subscription management command. The receive method
// converts a pushed message to convenient types for use in a type switch.
//
// psc := redis.PubSubConn{Conn: c}
// psc.Subscribe("example")
// for {
// switch v := psc.Receive().(type) {
// case redis.Message:
// fmt.Printf("%s: message: %s\n", v.Channel, v.Data)
// case redis.Subscription:
// fmt.Printf("%s: %s %d\n", v.Channel, v.Kind, v.Count)
// case error:
// return v
// }
// }
//
// Reply Helpers
//
// The Bool, Int, Bytes, String, Strings and Values functions convert a reply
// to a value of a specific type. To allow convenient wrapping of calls to the
// connection Do and Receive methods, the functions take a second argument of
// type error. If the error is non-nil, then the helper function returns the
// error. If the error is nil, the function converts the reply to the specified
// type:
//
// exists, err := redis.Bool(c.Do("EXISTS", "foo"))
// if err != nil {
// // handle error return from c.Do or type conversion error.
// }
//
// The Scan function converts elements of a array reply to Go types:
//
// var value1 int
// var value2 string
// reply, err := redis.Values(c.Do("MGET", "key1", "key2"))
// if err != nil {
// // handle error
// }
// if _, err := redis.Scan(reply, &value1, &value2); err != nil {
// // handle error
// }
//
// Errors
//
// Connection methods return error replies from the server as type redis.Error.
//
// Call the connection Err() method to determine if the connection encountered
// non-recoverable error such as a network error or protocol parsing error. If
// Err() returns a non-nil value, then the connection is not usable and should
// be closed.

To use a tagged revision:
go get gopkg.in/ini.v1
```sh
$ go get gopkg.in/ini.v1
```
To use with latest changes:
go get github.com/go-ini/ini
```sh
$ 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 := LoadSources(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 := LoadSources(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
```
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 := LoadSources(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:"|"`
Places []string `ini:"places,omitempty"`
None []int `ini:",omitempty"`
}
type Author struct {
Name string `ini:"NAME"`
Male bool
Age int
GPA float64
NeverMind string `ini:"-"`
*Embeded
}
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
Age = 21
GPA = 2.8
[Embeded]
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 := LoadSources(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 := LoadSources(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
```
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(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:"|"`
Places []string `ini:"places,omitempty"`
None []int `ini:",omitempty"`
}
type Author struct {
Name string `ini:"NAME"`
Male bool
Age int
GPA float64
NeverMind string `ini:"-"`
*Embeded
}
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
Age = 21
GPA = 2.8
[Embeded]
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）

Package context stores values shared during a request lifetime.
Note: gorilla/context, having been born well before `context.Context` existed,
does not play well > with the shallow copying of the request that
[`http.Request.WithContext`](https://golang.org/pkg/net/http/#Request.WithContext)
(added to net/http Go 1.7 onwards) performs. You should either use *just*
gorilla/context, or moving forward, the new `http.Request.Context()`.
For example, a router can set variables extracted from the URL and later
application handlers can access those values, or it can be used to store
sessions values to be saved at the end of a request. There are several
others common uses.
The idea was posted by Brad Fitzpatrick to the go-nuts mailing list:
http://groups.google.com/group/golang-nuts/msg/e2d679d303aa5d53
Here's the basic usage: first define the keys that you will need. The key
type is interface{} so a key can be of any type that supports equality.
Here we define a key using a custom int type to avoid name collisions:
package foo
import (
"github.com/gorilla/context"
)
type key int
const MyKey key = 0
Then set a variable. Variables are bound to an http.Request object, so you
need a request instance to set a value:
context.Set(r, MyKey, "bar")
The application can later access the variable using the same key you provided:
func MyHandler(w http.ResponseWriter, r *http.Request) {
// val is "bar".
val := context.Get(r, foo.MyKey)
// returns ("bar", true)
val, ok := context.GetOk(r, foo.MyKey)
// ...
}
And that's all about the basic usage. We discuss some other ideas below.
Any type can be stored in the context. To enforce a given type, make the key
private and wrap Get() and Set() to accept and return values of a specific
type:
type key int
const mykey key = 0
// GetMyKey returns a value for this package from the request values.
func GetMyKey(r *http.Request) SomeType {
if rv := context.Get(r, mykey); rv != nil {
return rv.(SomeType)
}
return nil
}
// SetMyKey sets a value for this package in the request values.
func SetMyKey(r *http.Request, val SomeType) {
context.Set(r, mykey, val)
}
Variables must be cleared at the end of a request, to remove all values
that were stored. This can be done in an http.Handler, after a request was
served. Just call Clear() passing the request:
context.Clear(r)
...or use ClearHandler(), which conveniently wraps an http.Handler to clear
variables at the end of a request lifetime.
The Routers from the packages gorilla/mux and gorilla/pat call Clear()
so if you are using either of them you don't need to clear the context manually.

securecookie
============
[![GoDoc](https://godoc.org/github.com/gorilla/securecookie?status.svg)](https://godoc.org/github.com/gorilla/securecookie) [![Build Status](https://travis-ci.org/gorilla/securecookie.png?branch=master)](https://travis-ci.org/gorilla/securecookie)
[![Sourcegraph](https://sourcegraph.com/github.com/gorilla/securecookie/-/badge.svg)](https://sourcegraph.com/github.com/gorilla/securecookie?badge)
securecookie encodes and decodes authenticated and optionally encrypted
cookie values.
Secure cookies can't be forged, because their values are validated using HMAC.
When encrypted, the content is also inaccessible to malicious eyes. It is still
recommended that sensitive data not be stored in cookies, and that HTTPS be used
to prevent cookie [replay attacks](https://en.wikipedia.org/wiki/Replay_attack).
## Examples
To use it, first create a new SecureCookie instance:
```go
// Hash keys should be at least 32 bytes long
var hashKey = []byte("very-secret")
// Block keys should be 16 bytes (AES-128) or 32 bytes (AES-256) long.
// Shorter keys may weaken the encryption used.
var blockKey = []byte("a-lot-secret")
var s = securecookie.New(hashKey, blockKey)
```
The hashKey is required, used to authenticate the cookie value using HMAC.
It is recommended to use a key with 32 or 64 bytes.
The blockKey is optional, used to encrypt the cookie value -- set it to nil
to not use encryption. If set, the length must correspond to the block size
of the encryption algorithm. For AES, used by default, valid lengths are
16, 24, or 32 bytes to select AES-128, AES-192, or AES-256.
Strong keys can be created using the convenience function GenerateRandomKey().
Once a SecureCookie instance is set, use it to encode a cookie value:
```go
func SetCookieHandler(w http.ResponseWriter, r *http.Request) {
value := map[string]string{
"foo": "bar",
}
if encoded, err := s.Encode("cookie-name", value); err == nil {
cookie := &http.Cookie{
Name: "cookie-name",
Value: encoded,
Path: "/",
Secure: true,
HttpOnly: true,
}
http.SetCookie(w, cookie)
}
}
```
Later, use the same SecureCookie instance to decode and validate a cookie
value:
```go
func ReadCookieHandler(w http.ResponseWriter, r *http.Request) {
if cookie, err := r.Cookie("cookie-name"); err == nil {
value := make(map[string]string)
if err = s2.Decode("cookie-name", cookie.Value, &value); err == nil {
fmt.Fprintf(w, "The value of foo is %q", value["foo"])
}
}
}
```
We stored a map[string]string, but secure cookies can hold any value that
can be encoded using `encoding/gob`. To store custom types, they must be
registered first using gob.Register(). For basic types this is not needed;
it works out of the box. An optional JSON encoder that uses `encoding/json` is
available for types compatible with JSON.

Package securecookie encodes and decodes authenticated and optionally
encrypted cookie values.
Secure cookies can't be forged, because their values are validated using HMAC.
When encrypted, the content is also inaccessible to malicious eyes.
To use it, first create a new SecureCookie instance:
var hashKey = []byte("very-secret")
var blockKey = []byte("a-lot-secret")
var s = securecookie.New(hashKey, blockKey)
The hashKey is required, used to authenticate the cookie value using HMAC.
It is recommended to use a key with 32 or 64 bytes.
The blockKey is optional, used to encrypt the cookie value -- set it to nil
to not use encryption. If set, the length must correspond to the block size
of the encryption algorithm. For AES, used by default, valid lengths are
16, 24, or 32 bytes to select AES-128, AES-192, or AES-256.
Strong keys can be created using the convenience function GenerateRandomKey().
Once a SecureCookie instance is set, use it to encode a cookie value:
func SetCookieHandler(w http.ResponseWriter, r *http.Request) {
value := map[string]string{
"foo": "bar",
}
if encoded, err := s.Encode("cookie-name", value); err == nil {
cookie := &http.Cookie{
Name: "cookie-name",
Value: encoded,
Path: "/",
}
http.SetCookie(w, cookie)
}
}
Later, use the same SecureCookie instance to decode and validate a cookie
value:
func ReadCookieHandler(w http.ResponseWriter, r *http.Request) {
if cookie, err := r.Cookie("cookie-name"); err == nil {
value := make(map[string]string)
if err = s2.Decode("cookie-name", cookie.Value, &value); err == nil {
fmt.Fprintf(w, "The value of foo is %q", value["foo"])
}
}
}
We stored a map[string]string, but secure cookies can hold any value that
can be encoded using encoding/gob. To store custom types, they must be
registered first using gob.Register(). For basic types this is not needed;
it works out of the box.

sessions
========
[![GoDoc](https://godoc.org/github.com/gorilla/sessions?status.svg)](https://godoc.org/github.com/gorilla/sessions) [![Build Status](https://travis-ci.org/gorilla/sessions.png?branch=master)](https://travis-ci.org/gorilla/sessions)
[![Sourcegraph](https://sourcegraph.com/github.com/gorilla/sessions/-/badge.svg)](https://sourcegraph.com/github.com/gorilla/sessions?badge)
gorilla/sessions provides cookie and filesystem sessions and infrastructure for
custom session backends.
The key features are:
* Simple API: use it as an easy way to set signed (and optionally
encrypted) cookies.
* Built-in backends to store sessions in cookies or the filesystem.
* Flash messages: session values that last until read.
* Convenient way to switch session persistency (aka "remember me") and set
other attributes.
* Mechanism to rotate authentication and encryption keys.
* Multiple sessions per request, even using different backends.
* Interfaces and infrastructure for custom session backends: sessions from
different stores can be retrieved and batch-saved using a common API.
Let's start with an example that shows the sessions API in a nutshell:
```go
import (
"net/http"
"github.com/gorilla/sessions"
)
var store = sessions.NewCookieStore([]byte("something-very-secret"))
func MyHandler(w http.ResponseWriter, r *http.Request) {
// Get a session. We're ignoring the error resulted from decoding an
// existing session: Get() always returns a session, even if empty.
session, _ := store.Get(r, "session-name")
// Set some session values.
session.Values["foo"] = "bar"
session.Values[42] = 43
// Save it before we write to the response/return from the handler.
session.Save(r, w)
}
```
First we initialize a session store calling `NewCookieStore()` and passing a
secret key used to authenticate the session. Inside the handler, we call
`store.Get()` to retrieve an existing session or create a new one. Then we set
some session values in session.Values, which is a `map[interface{}]interface{}`.
And finally we call `session.Save()` to save the session in the response.
Important Note: If you aren't using gorilla/mux, you need to wrap your handlers
with
[`context.ClearHandler`](http://www.gorillatoolkit.org/pkg/context#ClearHandler)
or else you will leak memory! An easy way to do this is to wrap the top-level
mux when calling http.ListenAndServe:
```go
http.ListenAndServe(":8080", context.ClearHandler(http.DefaultServeMux))
```
The ClearHandler function is provided by the gorilla/context package.
More examples are available [on the Gorilla
website](http://www.gorillatoolkit.org/pkg/sessions).

Package sessions provides cookie and filesystem sessions and
infrastructure for custom session backends.
The key features are:
* Simple API: use it as an easy way to set signed (and optionally
encrypted) cookies.
* Built-in backends to store sessions in cookies or the filesystem.
* Flash messages: session values that last until read.
* Convenient way to switch session persistency (aka "remember me") and set
other attributes.
* Mechanism to rotate authentication and encryption keys.
* Multiple sessions per request, even using different backends.
* Interfaces and infrastructure for custom session backends: sessions from
different stores can be retrieved and batch-saved using a common API.
Let's start with an example that shows the sessions API in a nutshell:
import (
"net/http"
"github.com/gorilla/sessions"
)
var store = sessions.NewCookieStore([]byte("something-very-secret"))
func MyHandler(w http.ResponseWriter, r *http.Request) {
// Get a session. Get() always returns a session, even if empty.
session, err := store.Get(r, "session-name")
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
// Set some session values.
session.Values["foo"] = "bar"
session.Values[42] = 43
// Save it before we write to the response/return from the handler.
session.Save(r, w)
}
First we initialize a session store calling NewCookieStore() and passing a
secret key used to authenticate the session. Inside the handler, we call
store.Get() to retrieve an existing session or a new one. Then we set some
session values in session.Values, which is a map[interface{}]interface{}.
And finally we call session.Save() to save the session in the response.
Note that in production code, we should check for errors when calling
session.Save(r, w), and either display an error message or otherwise handle it.
Save must be called before writing to the response, otherwise the session
cookie will not be sent to the client.
Important Note: If you aren't using gorilla/mux, you need to wrap your handlers
with context.ClearHandler as or else you will leak memory! An easy way to do this
is to wrap the top-level mux when calling http.ListenAndServe:
http.ListenAndServe(":8080", context.ClearHandler(http.DefaultServeMux))
The ClearHandler function is provided by the gorilla/context package.
That's all you need to know for the basic usage. Let's take a look at other
options, starting with flash messages.
Flash messages are session values that last until read. The term appeared with
Ruby On Rails a few years back. When we request a flash message, it is removed
from the session. To add a flash, call session.AddFlash(), and to get all
flashes, call session.Flashes(). Here is an example:
func MyHandler(w http.ResponseWriter, r *http.Request) {
// Get a session.
session, err := store.Get(r, "session-name")
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
// Get the previously flashes, if any.
if flashes := session.Flashes(); len(flashes) > 0 {
// Use the flash values.
} else {
// Set a new flash.
session.AddFlash("Hello, flash messages world!")
}
session.Save(r, w)
}
Flash messages are useful to set information to be read after a redirection,
like after form submissions.
There may also be cases where you want to store a complex datatype within a
session, such as a struct. Sessions are serialised using the encoding/gob package,
so it is easy to register new datatypes for storage in sessions:
import(
"encoding/gob"
"github.com/gorilla/sessions"
)
type Person struct {
FirstName string
LastName string
Email string
Age int
}
type M map[string]interface{}
func init() {
gob.Register(&Person{})
gob.Register(&M{})
}
As it's not possible to pass a raw type as a parameter to a function, gob.Register()
relies on us passing it a value of the desired type. In the example above we've passed
it a pointer to a struct and a pointer to a custom type representing a
map[string]interface. (We could have passed non-pointer values if we wished.) This will
then allow us to serialise/deserialise values of those types to and from our sessions.
Note that because session values are stored in a map[string]interface{}, there's
a need to type-assert data when retrieving it. We'll use the Person struct we registered above:
func MyHandler(w http.ResponseWriter, r *http.Request) {
session, err := store.Get(r, "session-name")
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
// Retrieve our struct and type-assert it
val := session.Values["person"]
var person = &Person{}
if person, ok := val.(*Person); !ok {
// Handle the case that it's not an expected type
}
// Now we can use our person object
}
By default, session cookies last for a month. This is probably too long for
some cases, but it is easy to change this and other attributes during
runtime. Sessions can be configured individually or the store can be
configured and then all sessions saved using it will use that configuration.
We access session.Options or store.Options to set a new configuration. The
fields are basically a subset of http.Cookie fields. Let's change the
maximum age of a session to one week:
session.Options = &sessions.Options{
Path: "/",
MaxAge: 86400 * 7,
HttpOnly: true,
}
Sometimes we may want to change authentication and/or encryption keys without
breaking existing sessions. The CookieStore supports key rotation, and to use
it you just need to set multiple authentication and encryption keys, in pairs,
to be tested in order:
var store = sessions.NewCookieStore(
[]byte("new-authentication-key"),
[]byte("new-encryption-key"),
[]byte("old-authentication-key"),
[]byte("old-encryption-key"),
)
New sessions will be saved using the first pair. Old sessions can still be
read because the first pair will fail, and the second will be tested. This
makes it easy to "rotate" secret keys and still be able to validate existing
sessions. Note: for all pairs the encryption key is optional; set it to nil
or omit it and and encryption won't be used.
Multiple sessions can be used in the same request, even with different
session backends. When this happens, calling Save() on each session
individually would be cumbersome, so we have a way to save all sessions
at once: it's sessions.Save(). Here's an example:
var store = sessions.NewCookieStore([]byte("something-very-secret"))
func MyHandler(w http.ResponseWriter, r *http.Request) {
// Get a session and set a value.
session1, _ := store.Get(r, "session-one")
session1.Values["foo"] = "bar"
// Get another session and set another value.
session2, _ := store.Get(r, "session-two")
session2.Values[42] = 43
// Save all sessions.
sessions.Save(r, w)
}
This is possible because when we call Get() from a session store, it adds the
session to a common registry. Save() uses it to save all registered sessions.

# Connection String
* Want to build go-sqlite3 with libsqlite3 on my linux.
When creating a new SQLite database or connection to an existing one, with the file name additional options can be given.
This is also known as a DSN string. (Data Source Name).
Use `go build --tags "libsqlite3 linux"`
Options are append after the filename of the SQLite database.
The database filename and options are seperated by an `?` (Question Mark).
* Want to build go-sqlite3 with libsqlite3 on OS X.
This also applies when using an in-memory database instead of a file.
Install sqlite3 from homebrew: `brew install sqlite3`
Options can be given using the following format: `KEYWORD=VALUE` and multiple options can be combined with the `&` ampersand.
Use `go build --tags "libsqlite3 darwin"`
This library supports dsn options of SQLite itself and provides additional options.
* Want to build go-sqlite3 with icu extension.
Boolean values can be one of:
* `0` `no` `false` `off`
* `1` `yes` `true` `on`
Use `go build --tags "icu"`

# Features
This package allows additional configuration of features available within SQLite3 to be enabled or disabled by golang build constraints also known as build `tags`.
[Click here for more information about build tags / constraints.](https://golang.org/pkg/go/build/#hdr-Build_Constraints)
### Usage
If you wish to build this library with additional extensions / features.
Use the following command.
```bash
go build --tags "<FEATURE>"
```
For available features see the extension list.
When using multiple build tags, all the different tags should be space delimted.
Example:
```bash
go build --tags "icu json1 fts5 secure_delete"
```
### Feature / Extension List
| Extension | Build Tag | Description |
|-----------|-----------|-------------|
| Additional Statistics | sqlite_stat4 | This option adds additional logic to the ANALYZE command and to the query planner that can help SQLite to chose a better query plan under certain situations. The ANALYZE command is enhanced to collect histogram data from all columns of every index and store that data in the sqlite_stat4 table.<br><br>The query planner will then use the histogram data to help it make better index choices. The downside of this compile-time option is that it violates the query planner stability guarantee making it more difficult to ensure consistent performance in mass-produced applications.<br><br>SQLITE_ENABLE_STAT4 is an enhancement of SQLITE_ENABLE_STAT3. STAT3 only recorded histogram data for the left-most column of each index whereas the STAT4 enhancement records histogram data from all columns of each index.<br><br>The SQLITE_ENABLE_STAT3 compile-time option is a no-op and is ignored if the SQLITE_ENABLE_STAT4 compile-time option is used |
| Allow URI Authority | sqlite_allow_uri_authority | URI filenames normally throws an error if the authority section is not either empty or "localhost".<br><br>However, if SQLite is compiled with the SQLITE_ALLOW_URI_AUTHORITY compile-time option, then the URI is converted into a Uniform Naming Convention (UNC) filename and passed down to the underlying operating system that way |
| App Armor | sqlite_app_armor | When defined, this C-preprocessor macro activates extra code that attempts to detect misuse of the SQLite API, such as passing in NULL pointers to required parameters or using objects after they have been destroyed. <br><br>App Armor is not available under `Windows`. |
| Disable Load Extensions | sqlite_omit_load_extension | Loading of external extensions is enabled by default.<br><br>To disable extension loading add the build tag `sqlite_omit_load_extension`. |
| Foreign Keys | sqlite_foreign_keys | This macro determines whether enforcement of foreign key constraints is enabled or disabled by default for new database connections.<br><br>Each database connection can always turn enforcement of foreign key constraints on and off and run-time using the foreign_keys pragma.<br><br>Enforcement of foreign key constraints is normally off by default, but if this compile-time parameter is set to 1, enforcement of foreign key constraints will be on by default |
| Full Auto Vacuum | sqlite_vacuum_full | Set the default auto vacuum to full |
| Incremental Auto Vacuum | sqlite_vacuum_incr | Set the default auto vacuum to incremental |
| Full Text Search Engine | sqlite_fts5 | When this option is defined in the amalgamation, versions 5 of the full-text search engine (fts5) is added to the build automatically |
| International Components for Unicode | sqlite_icu | This option causes the International Components for Unicode or "ICU" extension to SQLite to be added to the build |
| Introspect PRAGMAS | sqlite_introspect | This option adds some extra PRAGMA statements. <ul><li>PRAGMA function_list</li><li>PRAGMA module_list</li><li>PRAGMA pragma_list</li></ul> |
| JSON SQL Functions | sqlite_json | When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically |
| Secure Delete | sqlite_secure_delete | This compile-time option changes the default setting of the secure_delete pragma.<br><br>When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on.<br><br>The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur.<br><br>On the other hand, secure_delete can prevent fragments of sensitive information from lingering in unused parts of the database file after it has been deleted. See the documentation on the secure_delete pragma for additional information |
| Secure Delete (FAST) | sqlite_secure_delete_fast | For more information see [PRAGMA secure_delete](https://www.sqlite.org/pragma.html#pragma_secure_delete) |
| Tracing / Debug | sqlite_trace | Activate trace functions |
| User Authentication | sqlite_userauth | SQLite User Authentication see [User Authentication](#user-authentication) for more information. |

# User Authentication
This package supports the SQLite User Authentication module.
## Compile
To use the User authentication module the package has to be compiled with the tag `sqlite_userauth`. See [Features](#features).
## Usage
### Create protected database
To create a database protected by user authentication provide the following argument to the connection string `_auth`.
This will enable user authentication within the database. This option however requires two additional arguments:
- `_auth_user`
- `_auth_pass`
When `_auth` is present on the connection string user authentication will be enabled and the provided user will be created
as an `admin` user. After initial creation, the parameter `_auth` has no effect anymore and can be omitted from the connection string.
Example connection string:
Create an user authentication database with user `admin` and password `admin`.
`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin`
Create an user authentication database with user `admin` and password `admin` and use `SHA1` for the password encoding.
`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin&_auth_crypt=sha1`
### Password Encoding
The passwords within the user authentication module of SQLite are encoded with the SQLite function `sqlite_cryp`.
This function uses a ceasar-cypher which is quite insecure.
This library provides several additional password encoders which can be configured through the connection string.
The password cypher can be configured with the key `_auth_crypt`. And if the configured password encoder also requires an
salt this can be configured with `_auth_salt`.
#### Available Encoders
- SHA1
- SSHA1 (Salted SHA1)
- SHA256
- SSHA256 (salted SHA256)
- SHA384
- SSHA384 (salted SHA384)
- SHA512
- SSHA512 (salted SHA512)
### Restrictions
Operations on the database regarding to user management can only be preformed by an administrator user.
### Support
The user authentication supports two kinds of users
- administrators
- regular users
### User Management
User management can be done by directly using the `*SQLiteConn` or by SQL.
#### SQL
The following sql functions are available for user management.
| Function | Arguments | Description |
|----------|-----------|-------------|
| `authenticate` | username `string`, password `string` | Will authenticate an user, this is done by the connection; and should not be used manually. |
| `auth_user_add` | username `string`, password `string`, admin `int` | This function will add an user to the database.<br>if the database is not protected by user authentication it will enable it. Argument `admin` is an integer identifying if the added user should be an administrator. Only Administrators can add administrators. |
| `auth_user_change` | username `string`, password `string`, admin `int` | Function to modify an user. Users can change their own password, but only an administrator can change the administrator flag. |
| `authUserDelete` | username `string` | Delete an user from the database. Can only be used by an administrator. The current logged in administrator cannot be deleted. This is to make sure their is always an administrator remaining. |
These functions will return an integer.
- 0 (SQLITE_OK)
- 23 (SQLITE_AUTH) Failed to perform due to authentication or insufficient privileges
##### Examples
```sql
// Autheticate user
// Create Admin User
SELECT auth_user_add('admin2', 'admin2', 1);
// Change password for user
SELECT auth_user_change('user', 'userpassword', 0);
// Delete user
SELECT user_delete('user');
```
#### *SQLiteConn
The following functions are available for User authentication from the `*SQLiteConn`.
| Function | Description |
|----------|-------------|
| `Authenticate(username, password string) error` | Authenticate user |
| `AuthUserAdd(username, password string, admin bool) error` | Add user |
| `AuthUserChange(username, password string, admin bool) error` | Modify user |
| `AuthUserDelete(username string) error` | Delete user |
### Attached database
When using attached databases. SQLite will use the authentication from the `main` database for the attached database(s).

- Why I'm getting `no such table` error?
Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?
Each connection to :memory: opens a brand new in-memory sql database, so if
the stdlib's sql engine happens to open another connection and you've only
specified ":memory:", that connection will see a brand new database. A
workaround is to use "file::memory:?mode=memory&cache=shared". Every
connection to this string will point to the same in-memory database. See
[#204](https://github.com/mattn/go-sqlite3/issues/204) for more info.

// The immutable parameter is a boolean query parameter that indicates
// that the database file is stored on read-only media. When immutable is set,
// SQLite assumes that the database file cannot be changed,
// even by a process with higher privilege,
// and so the database is opened read-only and all locking and change detection is disabled.
// Caution: Setting the immutable property on a database file that
// does in fact change can result in incorrect query results and/or SQLITE_CORRUPT errors.
//
// go-sqlite3 adds the following query parameters to those used by SQLite:
// _loc=XXX
// Specify location of time format. It's possible to specify "auto".
// _busy_timeout=XXX
// Specify value for sqlite3_busy_timeout.
//
// _mutex=XXX
// Specify mutex mode. XXX can be "no", "full".
//
// _txlock=XXX
// Specify locking behavior for transactions. XXX can be "immediate",
// "deferred", "exclusive".
// _foreign_keys=X
// Enable or disable enforcement of foreign keys. X can be 1 or 0.
// _recursive_triggers=X
// Enable or disable recursive triggers. X can be 1 or 0.

// parameter, typically named ctx:

## Changes in v2
A context was created to allow cache of some SQL statements. See in the
documentation above how to use it.
The helpers were renamed to have a smaller name:
```go
PostgreSQLHelper{} -> PostgreSQL{}
MySQLHelper{} -> MySQL{}
SQLiteHelper{} -> SQLite{}
SQLServerHelper{} -> SQLServer{}

The old functions and helpers are still available for backward compatibility.
