The JSON5 Data Interchange FormatThe JSON5 数据交换格式
Abstract 摘要
The JSON5 Data Interchange Format is a proposed extension to JSON that aims to make it easier for humans to write and maintain by hand. It does this by adding some minimal syntax features directly from ECMAScript 5.1.JSON5 数据交换格式是一个提议的 JSON 扩展，旨在通过直接添加一些来自 ECMAScript 5.1 的最小语法特性，使人类更容易手动编写和维护。
1Introduction 1 介绍
The JSON5 Data Interchange Format (JSON5) is a superset of JSON that aims to alleviate some of the limitations of JSON by expanding its syntax to include some productions from ECMAScript 5.1.JSON5 数据交换格式（JSON5）是 JSON 的超集，旨在通过扩展其语法以包括一些来自 ECMAScript 5.1 的生产来缓解 JSON 的一些限制。
Similar to JSON, JSON5 can represent four primitive types (strings, numbers, Booleans, and null) and two structured types (objects and arrays).与 JSON 类似，JSON5 可以表示四种原始类型（字符串、数字、布尔值和 null）以及两种结构化类型（对象和数组）。
A string is a sequence of zero or more Unicode characters. Note that this citation references the latest version of Unicode rather than a specific release. It is not expected that future changes in the Unicode specification will impact the syntax of JSON5.字符串是由零个或多个 Unicode 字符组成的序列。请注意，此引用引用的是 Unicode 的最新版本，而不是特定版本。预计 Unicode 规范的未来变化不会影响 JSON5 的语法。
An object is an unordered collection of zero or more name/value pairs, where a name is a string or identifier and a value is a string, number, Boolean, null, object, or array.对象是一个无序集合，包含零个或多个键值对，其中键是一个字符串或标识符，值是字符串、数字、布尔值、null、对象或数组。
An array is an ordered sequence of zero or more values.数组是一个有序的值序列。
1.1Summary of Features 1.1 功能概述
The following ECMAScript 5.1 features, which are not supported in JSON, have been extended to JSON5.以下 ECMAScript 5.1 特性，这些特性在 JSON 中不受支持，已经被扩展到 JSON5 中。
Objects 对象
- Object keys may be an ECMAScript 5.1 IdentifierName.对象的键可以是 ECMAScript 5.1 的标识符名称。
- Objects may have a single trailing comma.对象可以有单个尾随逗号。
Arrays 数组
- Arrays may have a single trailing comma.数组可以有单个尾随逗号。
Strings 字符串
- Strings may be single quoted.字符串可以使用单引号。
- Strings may span multiple lines by escaping new line characters.字符串可以通过转义换行符跨越多行。
- Strings may include character escapes.字符串可以包含字符转义。

2Values 2 值
A JSON5 value must be an object, array, string, or number, or one of the three literal names true, false, or null.JSON5 值必须是一个对象、数组、字符串、数字，或者是三个字面量名称之一： true 、 false 或 null 。
JSON5Value: JSON5 值：JSON5Null JSON5 空值JSON5Boolean JSON5 布尔值JSON5String JSON5 字符串JSON5Number JSON5 数字JSON5Object JSON5 对象JSON5Array JSON5 数组# 3Objects 3 个对象
An object structure is represented as a pair of curly brackets surrounding zero or more name/value pairs (or members). A name is a string or identifier. A single colon comes after each name, separating the name from the value. A single comma separates a value from a following name. A single comma may follow the name/value pair. The names within an object should be unique.对象结构用一对花括号表示，其中包含零个或多个名称/值对（或成员）。名称是一个字符串或标识符。每个名称之后跟一个单冒号，将名称与值分开。一个值之后跟一个单逗号，与后面的名称分开。名称/值对之后可以跟一个单逗号。对象内的名称应该是唯一的。
JSON5Object: JSON5 对象：{}{JSON5MemberList,opt} { JSON5 成员列表, 选择}JSON5MemberList: JSON5 成员列表:JSON5Member JSON5 成员JSON5MemberList,JSON5MemberJSON5 成员列表, JSON5 成员JSON5Member: JSON5 成员:JSON5MemberName:JSON5ValueJSON5 成员名称: JSON5 值JSON5MemberName: JSON5 成员名称:JSON5Identifier JSON5 标识符JSON5String JSON5 字符串An object whose names are all unique is interoperable in the sense that all software implementations receiving that object will agree on the name-value mappings. When the names within an object are not unique, the behavior of software that receives such an object is unpredictable. Implementations may report the last name/value pair only, report an error or fail to parse the object, or report all of the name/value pairs, including duplicates.一个名称全部唯一的对象在互操作性方面是可行的，即所有接收该对象的软件实现都将同意名称-值映射。当对象内的名称不唯一时，接收此类对象的软件的行为是不可预测的。实现可能只报告最后一个名称/值对，报告错误或无法解析对象，或者报告所有名称/值对，包括重复项。
Implementations may make the ordering of object members visible to calling software. Implementations whose behavior does not depend on member ordering will be interoperable in the sense that they will not be affected by this.实现可能将对象成员的顺序对调用软件可见。那些行为不依赖于成员顺序的实现将在互操作性方面是可行的，即它们将不会受到影响。

5Strings 5 字符串
A string begins and ends with single or double quotation marks. The same quotation mark that begins a string must also end the string. All Unicode characters may be placed within the quotation marks, except for the characters that must be escaped: the quotation mark used to begin and end the string, reverse solidus, and line terminators.字符串以单引号或双引号开始和结束。开始字符串的相同引号也必须结束字符串。所有 Unicode 字符都可以放在引号内，除了必须转义的字符：用于开始和结束字符串的引号、反斜杠和换行符。

Any character may be escaped. If the character is in the Basic Latin or Latin-1 Supplement Unicode character ranges (U+0000 through U+00FF), then it may be represented as a four-character sequence: a reverse solidus, followed by the lower case letter x, followed by two hexadecimal digits that encode the character’s code point. A reverse solidus followed by the lower case letter x must be followed by two hexadecimal digits.任何字符都可以进行转义。如果字符在基本拉丁或拉丁-1 补充 Unicode 字符范围内（U+0000 至 U+00FF），则可以表示为四个字符的序列：一个反斜杠，后跟小写字母 x ，然后是两个表示字符代码点的十六进制数字。一个反斜杠后跟小写字母 x 必须后跟两个十六进制数字。
If the character is in the Basic Multilingual Plane (U+0000 through U+FFFF), then it may be represented as a six-character sequence: a reverse solidus, followed by the lower case letter u, followed by four hexadecimal digits that encode the character’s code point. A reverse solidus followed by the lower case letter u must be followed by four hexadecimal digits. The hexadecimal letters A though F can be upper or lower case.如果字符位于基本多语言平面（U+0000 至 U+FFFF），则它可以表示为一个六字符序列：一个反斜杠，后跟小写字母 u ，然后是四个十六进制数字，这些数字编码了字符的代码点。一个反斜杠后跟小写字母 u 必须后跟四个十六进制数字。十六进制字母 A 到 F 可以是大写或小写。
Example 1 (Informative) 示例 1（信息性）
A string containing only a single reverse solidus character may be represented as '\x5C' or '\u005C'.仅包含单个反斜杠字符的字符串可以表示为 ‘\x5C’ 或 ‘\u005C’ 。
To escape an extended character that is not in the Basic Multilingual Plane, the character is represented as a 12-character sequence, encoding the UTF-16 surrogate pair.要转义不在基本多语言平面的扩展字符，该字符表示为一个 12 字符序列，编码 UTF-16 代理对。
Example 2 (Informative) 示例 2（信息性）
A string containing only the musical score character 🎼 (U+1F3BC) may be represented as '\uD83C\uDFBC'.仅包含音乐符号字符🎼（U+1F3BC）的字符串可以表示为 ‘\uD83C\uDFBC’ 。
Alternatively, there are two-character sequence escape representations of some popular characters. A decimal digit must not follow a reverse solidus followed by a zero.或者，还有一些流行字符的两种字符序列转义表示。一个十进制数字不能跟在反斜杠后跟零之后。

'AC/DC'
5.2Paragraph and Line Separators5.2 段落和换行分隔符
Like JSON, JSON5 allows the Unicode code points U+2028 and U+2029 to appear unescaped in strings. Since ECMAScript 5.1 does not allow these code points in strings, authors should avoid including them in JSON5 documents. JSON5 parsers should produce a warning when they are found unescaped in strings. JSON5 generators should escape these code points in strings.与 JSON 一样，JSON5 允许 Unicode 码点 U+2028 和 U+2029 在字符串中未转义出现。由于 ECMAScript 5.1 不允许这些码点出现在字符串中，作者应避免在 JSON5 文档中包含它们。当 JSON5 解析器在字符串中找到未转义的这些码点时，应产生警告。JSON5 生成器应在字符串中转义这些码点。
6Numbers 6 个数字
The representation of numbers is similar to that used in most programming languages. A number may be represented in in base 10 using decimal digits, base 16 using hexadecimal digits, or the IEEE 754 values positive infinity, negative infinity, or NaN.数字表示与大多数编程语言中使用的表示类似。一个数字可以用十进制数字表示为十进制，用十六进制数字表示为十六进制，或者用 IEEE 754 值表示为正无穷、负无穷或 NaN。

9Grammar 9 语法
JSON5 is defined by a lexical grammar and a syntactic grammar. The lexical grammar defines productions that translate text into tokens, and the syntactic grammar defines productions that translate tokens into a JSON5 value.JSON5 由词法语法和句法语法定义。词法语法定义了将文本转换为标记的生产，句法语法定义了将标记转换为 JSON5 值的生成。
All productions that do not begin with the characters “JSON5” are defined by productions of the ECMAScript 5.1 Lexical Grammar.所有不以“JSON5”字符开头的生产由 ECMAScript 5.1 词法语法定义。
9.1Lexical Grammar 9.1 词汇语法
The lexical grammar for JSON5 has as its terminal symbols characters (Unicode code units) that conform to the rules for JSON5SourceCharacter. It defines a set of productions, starting from the goal symbol JSON5InputElement, that describe how sequences of such characters are translated into a sequence of input elements.JSON5 的词法语法以其终端符号为符合 JSON5SourceCharacter 规则的字符（Unicode 代码单元）。它定义了一组生产，从目标符号 JSON5InputElement 开始，描述了此类字符序列如何转换为输入元素序列。
Input elements other than white space and comments form the terminal symbols for the syntactic grammar for JSON5 and are called tokens. These tokens are the identifiers, literals, and punctuators of the JSON5 language. Simple white space and comments are discarded and do not appear in the stream of input elements for the syntactic grammar.输入元素（除了空白和注释）构成了 JSON5 语法中的终结符号，被称为标记。这些标记是 JSON5 语言的标识符、字面量和标点符号。简单的空白和注释将被丢弃，不会出现在输入元素的语法流中。
Productions of the lexical grammar are distinguished by having two colons “::” as separating punctuation.词法语法的产生式通过两个冒号“::”作为分隔标点来区分。

The syntactic grammar for JSON5 has tokens defined by the lexical grammar as its terminal symbols. It defines a set of productions, starting from the goal symbol JSON5Text, that describe how sequences of tokens can form syntactically correct JSON5 values.JSON5 的语法语法由词法语法定义的词素作为其终端符号。它定义了一组从目标符号 JSON5Text 开始的产生式，描述了如何将词素的序列形成语法正确的 JSON5 值。
When a stream of characters is to be parsed as a JSON5 value, it is first converted to a stream of input elements by repeated application of the lexical grammar; this stream of input elements is then parsed by a single application of the syntactic grammar. The program is syntactically in error if the tokens in the stream of input elements cannot be parsed as a single instance of the goal nonterminal JSON5Text, with no tokens left over.当一个字符流被解析为 JSON5 值时，它首先通过重复应用词法语法被转换为输入元素流；然后通过单次应用语法语法来解析这个输入元素流。如果输入元素流中的词素不能被解析为目标非终结符 JSON5Text 的单个实例，且没有剩余的词素，则程序在语法上是错误的。
Productions of the syntactic grammar are distinguished by having just one colon “:” as punctuation.语法句子的生产以只有一个冒号“:”作为标点符号为特征。

An implementation may set limits on the size of texts that it accepts, the maximum depth of nesting, the range and precision of numbers, and the length and character contents of strings.实现可以对其接受的文本大小、最大嵌套深度、数字的范围和精度以及字符串的长度和字符内容设置限制。
