Preface

Kindle 的 Clippings.txt 里面有一大堆重复的(子集关系)标记, 并且还有很多无用的冗余信息!
所以写了一个简单的脚本去处理。

Content

  • 书籍分类

const cfg = {
  file: "clippings.txt",
  book: "重启咲良田"
}

import fs from "node:fs";

function trim(s: string) {
  return s.replace(/(^。*)|(^\s*)|(\s*$)/g, "");
}

let filename = cfg.file;
let content = fs.readFileSync(filename, "utf8");

let lines = content.split("==========\n")
  .filter(s=>s.startsWith(cfg.book))
  .map(s => trim(s.split("\n").slice(-2)[0]))
  .filter(s => s !== "");

// console.log(lines)

let result: string[] = [lines[0]];

// 取内容最全的一行
for (let i = 1; i < lines.length; ++i) {
  let l = result.length - 1;
  if (lines[i].includes(result[l]))
    result[l] = lines[i];
  else if (!result[l].includes(lines[i]))
    result.push(lines[i]);
}

// console.log(result);

fs.writeFileSync(filename + ".bak", result.join("\n"), "utf8");
