其代码直接采用了剑桥大学Graham Hutton教授所著的Programming in Haskell一书中的 Parser组合子,这些组合子很容易在网上搜到。在 Google上搜Monadic Parser Combinator,排在最顶上的文章就是Graham Hutton教授关于Haskell Parser组合子的论文,发表得很早了,但是,这种原理性的东西,是不会过时的。 -- Functional parsing ...
Parser labels The address parser can technically use any string labels that are defined in the training data, but these are the ones currently defined, based on the fields defined inOpenCage's address-formatting library, as well as a few added by libpostal to handle specific patterns: ...

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...

Some changes may require us to change provided interfaces. While we try to implement functions in a generic way so that no future changes are required, we cannot promise a completely stable API. As we have to keep up with changes in behavior made upstream, we may lag behind in some areas...
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...
The parser program will be compiled using the file parser.cpp and the translator program will be compiled using the file translator.cpp file. In both cases any .cpp files with names starting with my will be also included together with the ...
code transformation), or a composition of widgets for visualising the text processed by the Parser. An important aspect of the Builder pattern that differentiates it from other creational patterns is that it supports the creation of complex objects in a step-by-step process, rather than all-at-...
