Flesch-Kincaid计算器Jekyll插件所属类别及展示方案咨询

我打算开发我的第一个Jekyll插件，目标是利用Flesch-Kincaid阅读难度算法，给页面中每个<p>标签或带有[data-read-level]标记的元素添加数据属性。

Flesch阅读难度得分公式：

Flesch Reading Ease Score = 206.835 − 1.015 × ( Total Words / Total Sentences ) − 84.6 × ( Total Syllables / Total Words )

我有两个疑问：

• 这个插件属于Jekyll插件的哪一类别？我个人认为是generator类。
• 有没有比添加数据属性更好的结果展示方式？

我已经写了一个初步可用的JavaScript版本，目前仅支持英文，还需要进一步完善：

// Flesch Reading Ease Score = 206.835 − 1.015 × ( Total Words / Total Sentences ) − 84.6 × ( Total Syllables / Total Words )

let fkExamine = function() {
    window.addEventListener('DOMContentLoaded', init);

    const fkConstA = 206.835;
    const fkConstB = 1.015;
    const fkConstC = 84.6;

    function init() {
      console.log('--      fkExamine.js initiated');
      let parseArray = [].slice.call(document.querySelectorAll('p, [data-read-level]'));
      parseArray.map(function(parseItem) {
        let txtContent = parseItem.textContent;
        let totalWords = getTotalWords(txtContent);
        let totalSentences = getTotalSentences(txtContent);
        let totalSyllables = getTotalSyllables(txtContent);

        let fkScore = fkConstA - fkConstB * (totalWords / totalSentences) - fkConstC * (totalSyllables / totalWords);
        parseItem.setAttribute('fk-score', fkScore);
      });
    }

    function getTotalWords(input) {
      const words = input.split(' ');
      return words.filter(word => word !== '').length;
    }

    function getTotalSentences(input) {
      return input.match(/[\w|\)][.?!](\s|$)/g).length;
    }

    function getTotalSyllables(input) {
      let syllables = 0;
      let words = input.split(' ');
      words = words.filter(word => word !== '');

      for(let i = 0; i < words.length; i++) {
        words[i].toLowerCase();
        words[i].replace(/(?:[^laeiouy]es|ed|[^laeiouy]e)$/, '');
        words[i].replace(/^y/, '');
        syllables += words[i].match(/[aeiouy]{1,2}/g).length;
      }
      return syllables;
    }
}();
