When we use an existing i18n library for internationalization/localization, We will write the following documents: {"En": {"name": "Enter Name"}, "zh-CN": {"name": "Enter name "}} ExceptenAndzh-CNAre there other keys? What are their composition rules? Let's take a closer look at these Language tags! Syntax Rules Note that the following uses the ABNF language description (for the

ArticleDirectory Extended bacos paradigm BNF is a language used to represent context-independent grammar. It describes a type of formal language. Although the bacos paradigm can also represent the syntax of some natural languages, it is still more widely usedProgramThe syntax representation of the design language, instruction set, and communication protocol. Most textbooks in programming language or formal semantics use the bacos paradigm. There are also some variants of the baco

. The h.248 protocol is a text-based protocol based on the ABNF (extended BNF) grammar, which defines the components and specific contents of the h.248 message. The specifics of the h.248 protocol are not discussed in this article, and interested readers can get more from the reference resources. We only focus on the NAME syntax definition, as follows:NAME = Alpha *63 (Alpha/digit/"_") Alpha =%x41-5a/%x61-7a ; A-Z, a-zdigit =%x30-39 ; di

URL encoding is a troublesome task. RFC 3986 is a standard for uri. Section 2nd defines how characters are represented in Uris, section 3rd classifies a URI as scheme, hier-part, query, and fragment components. According to this RFC, a URI is composed from a limited set of characters consisting of digits, letters, and a few graphic symbols. Appendix A defines ABNF. Such as URL, http://www.qingbo.org /?

Backus paradigm (EBNF) and the expanded Basque paradigm (ABNF).A BNF specification is a set of rules written in the following form:The left side of the equation is usually a non-terminating character, followed by a ::= Symbol, which stands for "can be swapped". Right of the formula Expression Consists of one or more symbol sequences, which are used to derive the meaning of the left symbol. The BNF specification fundamentally says, "whatever the left
