@ltd/j-toml v0.5

@ltd/j-toml v0.5 is an implementation of TOML v0.5 ("Tom's Obvious, Minimal Language") written by LongTengDao,
which is the best config format he had ever seen.
(Obviously for exhausted people who tried to design that.)

@ltd/j-toml v0.5 是龙腾道为 汤小明语 v0.5（“汤小明的小巧明晰语言”）写的实现。
——这 TM 可能是“我”见过最好的配置文件书写格式了。
——对于亲手折腾到爆炸的人而言。

Node.js

npm install @ltd/j-toml

[SubTable]

I_am_normal    = "..."
hasOwnProperty = "..."
constructor    = "..."
__proto__      = "..."

const TOML = require('@ltd/j-toml');

const rootTable = TOML.parse(src, 0.5, '\n');

rootTable.SubTable.I_am_normal    === "..." // true
rootTable.SubTable.hasOwnProperty === "..." // true
rootTable.SubTable.constructor    === "..." // true
rootTable.SubTable.__proto__      === "..." // true

TOML.parse

TOML.parse(source, version, multiLineJoiner[, useBigInt=true[, xOptions]]);

0. source required

   • type: string
   • desc:
     • Auto trim start BOM (if exists) of the UTF text.
     • 会自动剔除 UTF 文本开头的 BOM 标签（如果有的话）。

1. version required

   • type: 0.5
   • desc:
     • You must specify it explicitly (though it can't be other value for the time being).
     • 你必须显式地进行指定（尽管目前还不能使用别的值）。

2. multiLineJoiner required

   • type: string
   • desc:
     • For the multi-line strings, use what to join the lines for result.
       Note that TOML always use "\n" or "\r\n" split the source lines while parsing, which defined in TOML spec.
     • 对于多行字符串，用什么来拼接各行。
       注意在解析 TOML 源时，按照 TOML 规范的要求，行分隔符总是 "\n" 或 "\r\n"。

3. useBigInt

   • type: boolean / number
   • default: true
   • desc:
     • Specify whether you want or not to use BigInt for integer type value. number type value allows you to control it by a max limit (and the negative limit from -useBigInt, if useBigInt>=0; otherwise as a min limit, and the positive limit is ~useBigInt).
     • 指定你是否要用 BigInt 来实现整数类型的值。number 类型的值允许你精确控制超过多少才使用 BigInt（自动通过 -useBigInt 获取负向界限，如果 useBigInt>=0；否则通过 ~useBigInt 获取正向界限）。

4. xOptions

   • type: object
   • desc:
     • The extensional features not in the spec.
       Include keeping the key/value pairs order of tables, integers larger than long, comment information, null value, mixed-type array, multi-line inline table with trailing comma even no comma, interpolation string, custom constructor, etc.
       They are private experimental discouraged features.
       See https://GitHub.com/LongTengDao/j-toml/blob/master/docs/xOptions.md.
     • 标准中所没有的扩展功能。
       包括保持表中键值对的顺序、超出长整型的整数、保留注释信息、null 值、跨行行内表及尾逗号甚至省略逗号、混合类型的数组、插值字符串、自定义构造器等。
       私有实验期功能，不建议随意使用。
       详见 https://GitHub.com/LongTengDao/j-toml/blob/master/docs/xOptions.md。

• return

  • type: object
  • desc:
    • Return the root table (tables parsed by this implementation are objects without any extended properties).
    • 返回根表（本实现解析出的表，是没有任何继承属性的对象）。

• throw

  • desc:
    • If the arguments not meet the requirement, there will be an error; if there is any error with the source, the error object will has a number type property named lineIndex to help locating that.
    • 如果参数不符合要求，会抛出错误；如果源文本有错误，错误对象会有一个名为 lineIndex 的数值类型的属性来帮助定位。
