装逼神句———有道词典命令行查询工具

2018-01-29

1、装逼说明

不喜欢安装有道词典的应用程序，因为太耗资源还一堆广告，但是用浏览器打开dict.youdao.com也挺麻烦的，不是吗？快来试试有道词典命令行工具吧！

2、看图装逼

example

3、自已装逼

3.1 安装

1	npm install yddict -g

3.2 使用说明

1	yd <要查询的单词>

在/usr/local/lib/node_modules/yddict/目录下，可以进行一些自定义，或者更改查询的来源，
主要源码 index.js：

#!/usr/bin/env node
const request = require('request');
const cheerio = require('cheerio');
const chalk = require('chalk');
const fs = require('fs');
const Spinner = require('cli-spinner').Spinner;
const isChinese = require('is-chinese')
const urlencode = require('urlencode');
const spinner = new Spinner('努力查询中... %s');
const home = process.env[(process.platform == 'win32') ? 'USERPROFILE' : 'HOME'];
const configFile = home + "/config.json";
let color = 'gray';//更改查询结果的文字颜色

spinner.setSpinnerString('|/-\\');
spinner.start();

const readFile = (filename, encoding) => {

    try {
        return fs.readFileSync(filename).toString(encoding);
    }
    catch (e) {
        return null;
    }
};

const config = JSON.parse(readFile(configFile,"utf8"));

const input = process.argv.slice(2)
const word = input.join(' ')
const isCn = isChinese(word);
const URL = isCn ? `http://dict.youdao.com/w/eng/${urlencode(word)}`:`http://dict.youdao.com/w/${urlencode(word)}`

const options = {
  'url':URL
};

if(config){
  if(config.proxy){
    options.proxy = config.proxy;
  }
  if(config.color){
    color = config.color;
  }
}

const color_output = chalk.keyword(color);
request(options,(error, response, body)=>{
  const $ = cheerio.load(body, {
    ignoreWhitespace: true,
    xmlMode: true
  });
  let result = '';

  spinner.stop(true);
  if(isCn){
    $('div.trans-container > ul').find('p.wordGroup').each(function(i,elm){
      result = $(this).text().replace(/\s+/g," ");
    });
  }else{
    result = $('div#phrsListTab > div.trans-container > ul').text();
  }
  // phrase
  if (result === '') {
    result = $('div#webPhrase > p.wordGroup').text();
  }
  // sentence
  if (result === '') {
    result = $('div#fanyiToggle > div.trans-container > p:nth-child(2)').text();
  }
  console.log(color_output(result));

});
