一、简介

TOML，全称为Tom's Obvious, Minimal Language，是一种易读的配置文件格式，旨在成为一个极简的数据序列化语言。TOML的设计原则之一是保持简洁性，易读性，同时提供足够的灵活性以满足各种应用场景。

TOML文件由多个表（table）组成，每个表包含一组键值对。键值对由键名、等号（或冒号），以及对应的值组成。TOML支持嵌套表，可以构建层次结构，使得配置文件更加结构化。

二、用法

github官方地址
GitHub - BurntSushi/toml: TOML parser for Golang with reflection.

# 一个包含各种数据类型的 TOML 示例StringValue = "Hello, World!"MultilineString = """
This is a
multi-line
string.
"""IntegerValue = 42FloatValue = 3.14BooleanValue = trueArrayValues = [1, 2, 3][[Table]]
NestedString = "Nested String 1"
NestedInteger = 123[[Table]]
NestedString = "Nested String 2"
NestedInteger = 456
[[Table.NnTables]]
NnString = "NnTable String 2"
NnInteger = 456
[[Table.NnTables]]
NnString = "NnTable String 2"
NnInteger = 456[[Table]]
NestedString = "Nested String 3"
NestedInteger = 789
[[Table.NnTables]]
NnString = "NnTable String 1"
NnInteger = 789[Maps]
[Maps.Map1]
NestedString = "Map Nested String 1"
NestedInteger = 111[Maps.Map2]
NestedString = "Map Nested String 2"
NestedInteger = 222DatetimeValue = 2022-01-11T12:34:56Z

对应的go文件：注意命名大写且要和toml文件一致

type Config struct {StringValue     stringMultilineString stringIntegerValue    intFloatValue      float64BooleanValue    boolArrayValues     []intTable           []NestedTableMaps            map[string]NestedTableDatetimeValue   time.Time
}type NestedTable struct {NestedString  stringNestedInteger intNnTables      []NnTable
}
type NnTable struct {NnString  stringNnInteger int
}
