它所parse的文法是p (op p)*,这与我们的定义的Expr: ExprT (Op ExprT)*等同,因此Expr的parser可以用chainl1实现。 第一个参数p不难理解,但是第二个参数op就比较迷惑,为什么它的类型是Parser<('a -> 'a -> 'a)>?下边将演示工它的作过程来解释它的意义: 我们定义let pExpr: Parser<int> = chainl1...

In Haskell this is handled by the Garbage Collector, but in C these combinators will need to take destructor functions as input, which say how clean up any partial data that has been collected. Here are the main combinators and how to use then. mpc_parser_t *mpc_expect(mpc_parser_t ...
Parsley is a fast and modern parser combinator library for Scala based loosely on a Haskell-style parsec API. How do I use it? Parsley is distributed on Maven Central, and can be added to your project via: // SBT libraryDependencies += "com.github.j-mie6" %% "parsley" % "4.6.0"...

(stlc-in-a-week; day-1) 写在前面 这一系列 tutorials 的起因还要追溯到这学期选的 PL 课, 一条贯穿课程始终的暗线就是用 Haskell 来实现一门完备的 (函数式) 语言 (包括相应的解释器), 也就是著名的simply-typed lambda calculus, 需要从零开始定义语法、语义、实现两种不同的evaluation strategy(i.e....
The Cat syntactic parser is written using the Myna TypeScript/JavaScript library, and has the following grammar: export var catGrammar = new function() { var _this = this; this.identifier = m.identifier.ast; this.integer = m.integer.ast; this.true = m.keyword("true").ast; this.false...
还有各种零散的关于Parsing的书和论文,像Paring Techniques A Practical Guide这本,以及好几篇Parser Combinator相关的论文。懒得去翻论文名了,有人对这个有兴趣我再发论文名图形学:我是图形学弱鸡,目前书库里只收藏了一本Real Time Rendering还没看计算理论:形式语言、自动机:跟着课学的,感觉国内教材也还可以。。。
