|
||||
- 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.
|
||||

|
||||
|
||||
## 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
|
||||
```

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）
