Installation

To use a tagged revision:

go get gopkg.in/ini.v1

To use with latest changes:

go get github.com/go-ini/ini
Testing

If you want to test on your machine, please apply -t flag:

go get -t gopkg.in/ini.v1

Getting Started

Loading from data sources

A Data Source is either raw data in type []byte or a file name with type string and you can load as many as data sources you want. Passing other types will simply return an error.

cfg, err := ini.Load([]byte("raw data"), "filename")

Or start with an empty object:

cfg := ini.Empty()

When you cannot decide how many data sources to load at the beginning, you still able to Append() them later.

err := cfg.Append("other file", []byte("other raw data"))
Working with sections

To get a section, you would need to:

section, err := cfg.GetSection("section name")

For a shortcut for default section, just give an empty string as name:

section, err := cfg.GetSection("")

When you're pretty sure the section exists, following code could make your life easier:

section := cfg.Section("")

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:

err := cfg.NewSection("new section")

To get a list of sections or section names:

sections := cfg.Sections()
names := cfg.SectionStrings()
Working with keys

To get a key under a section:

key, err := cfg.Section("").GetKey("key name")

Same rule applies to key operations:

key := cfg.Section("").Key("key name")

To check if a key exists:

yes := cfg.Section("").HasKey("key name")

To create a new key:

err := cfg.Section("").NewKey("name", "value")

To get a list of keys or key names:

keys := cfg.Section("").Keys()
names := cfg.Section("").KeyStrings()

To get a clone hash of keys and corresponding values:

hash := cfg.GetSection("").KeysHash()
Working with values

To get a string value:

val := cfg.Section("").Key("key name").String()

To validate key value on the fly:

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):

val := cfg.Section("").Key("key name").Value()

To check if raw value exists:

yes := cfg.Section("").HasValue("test value")

To get value with types:

// 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?

[advance]
ADDRESS = """404 road,
NotFound, State, 5000
Earth"""

Not a problem!

cfg.Section("advance").Key("ADDRESS").String()

/* --- start ---
404 road,
NotFound, State, 5000
Earth
------  end  --- */

That's cool, how about continuation lines?

[advance]
two_lines = how about \
	continuation lines?
lots_of_lines = 1 \
	2 \
	3 \
	4

Piece of cake!

cfg.Section("advance").Key("two_lines").String() // how about continuation lines?
cfg.Section("advance").Key("lots_of_lines").String() // 1 2 3 4

Note that single quotes around values will be stripped:

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:

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:

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

To auto-split value into slice:

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(",")
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:

// ...
err = cfg.SaveTo("my.ini")
err = cfg.SaveToIndent("my.ini", "\t")

Another way to save is writing to a io.Writer interface:

// ...
cfg.WriteTo(writer)
cfg.WriteToIndent(writer, "\t")

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.

NAME = ini

[author]
NAME = Unknwon
GITHUB = https://github.com/%(NAME)s

[package]
FULL_NAME = github.com/go-ini/%(NAME)s

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.

NAME = ini
VERSION = v1
IMPORT_PATH = gopkg.in/%(NAME)s.%(VERSION)s

[package]
CLONE_URL = https://%(IMPORT_PATH)s

[package.sub]

cfg.Section("package.sub").Key("CLONE_URL").String()	// https://gopkg.in/ini.v1
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.

[features]
-: Support read/write comments of keys and sections
-: Support auto-increment of key names
-: Support load multiple files to overwrite key values

cfg.Section("features").KeyStrings()	// []{"#1", "#2", "#3"}
Map To Struct

Want more objective way to play with INI? Cool.

Name = Unknwon
age = 21
Male = true
Born = 1993-01-01T20:17:05Z

[Note]
Content = Hi is a good man!
Cities = HangZhou, Boston

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.

// ...
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?

type Embeded struct {
	Dates  []time.Time `delim:"|"`
	Places []string
	None   []int
}

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?

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
None =
Name Mapper

To save your time and make your code cleaner, this library supports 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:

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.

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:

type Child struct {
	Age string
}

type Parent struct {
	Name string
	Child
}

type Config struct {
	City string
	Parent
}

Example configuration:

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.

type Child struct {
	Age string
}

type Parent struct {
	Name string
	Child `ini:"Parent"`
}

type Config struct {
	City string
	Parent
}

Example configuration:

City = Boston

[Parent]
Name = Unknwon
Age = 21

Getting Help

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, 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)
