RE-Build：用自然语言去编写正则表达式

· 阅读需 1 分钟

Build regular expressions with natural language.

由来

你是否遇到过这么复杂的正则表达式呢？

var ipMatch = /(?:(?:1\d\d|2[0-4]\d|25[0-5]|[1-9]\d|\d)\.){3}(?:1\d\d|2[0-4]\d|25[0-5]|[1-9]\d|\d)\b/;

怎么办

使用re-build

var ipNumber = RE.group(
        RE  ("1").then.digit.then.digit
        .or ("2").then.oneOf.range("0", "4").then.digit
        .or ("25").then.oneOf.range("0", "5")
        .or .oneOf.range("1", "9").then.digit
        .or .digit
    ),

    ipMatch = RE.matching.exactly(3).group( ipNumber.then(".") )
                .then(ipNumber).then.wordBoundary.regex;

安装

通过npm ： `

npm install re-build

通过bower

bower install re-build
