JSON Parser 100% From Scratch in Haskell (only 111 lines)

推荐理由

this guy writes a json parser live, giving his intuition along the way. It's helped me immensely.

说明

这是2019年由Tsoding发布的一部教程，主题归在Functional programming。它讲的是haskell parser combinators这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：Tsoding live-codes a JSON parser from scratch in Haskell in about 111 lines, using only the standard library. It is an edited Twitch stream that explains the intuition behind parser combinators, functors, applicatives and monads.这些读者给出的理由，核心是：HN recommends it as a hands-on way to understand Haskell and parser combinators by watching a parser get built live.讲法不绑某一条新闻，过几年仍然可以当材料看。从2020年到2022年，有3位不同的读者在3个不同月份把它推荐出来，其中明确叫别人去看的有0次。适合打开电脑跟着做的人。如果只听不练，这集的价值会少一半。如果已经会了基本定义，就把注意力放在它怎么把haskell parser combinators变成能跟着复述的例子。
