不用学习一门新的语言,如知名的parser generator: ANTLR,pegjs,nearley等,开发者首先要会BNF,然后还要学习各自的语法。而使用parser combinator,开发者可以使用他们最熟悉的主语言 因为parser generator是通过一门语言生成代码(即生成parser),所以不易debugger和类型检查。 更强大的表达能力,parser combinator拥有宿主语言...
语法分析组合子(Parser Combinator)可以支持定义小型解析器(parser),然后可以组合这些解析器(parser),来解析任何东西,比如从字符串到编程语言。因为在某些语言中存在像monadic LL(infinity)这样的短语,和一些看起来很复杂的语法,语法分析组合子(Parser Combinator)猛一看会很复杂,但实际上它非常简单,而且用起来很有趣。
Bennu is a Javascript parser combinator library based onParsec. Parser combinators allow complex parsers to be created from a set of simple building blocks. Compared to other parsing techniques, combinatorial parsers can be written more quickly and integrate better with the host language. ...
什么是Parser Combinator? Parser Combinator在函数式编程中如何应用? 如何使用Parser Combinator解析复杂的语法结构? 词法分析和语法分析 词法分析(lexical analysis)1 和语法分析(syntactic analysis,又称为 parsing)2,同属于编译器的前端部分。词法分析器(lexer)将输入拆分为一个个的 token,然后语法分析器根据特定的语法...

Json literal: (expected: string) => Parser<string> map: <A, B>(a: Parser<A>, f: (_: A) => B) => Parser<B> maybe: <A>(a: Parser<A>) => Parser<A> pair: <A, B>(a: Parser<A>, b: Parser<B>) => Parser<[A, B]> ...
jsx parser by parser combinators.. Latest version: 0.1.2, last published: 3 years ago. Start using @saber2pr/jsx-ast-parser in your project by running `npm i @saber2pr/jsx-ast-parser`. There are no other projects in the npm registry using @saber2pr/jsx-a
Parsec CoffeeScriptCS based on parser combinators. The project's aim is to add static metaprogramming (i.e. macros + syntax extensibility) to Coffee Script (CS), similar to how Metalua adds such features to Lua. The resulting compiler, once merged with the official compiler, should be usable...
