📚📚 Straw 📚📚

Straw 是一个在 macOS 系统下跨应用程序, 实现划词翻译的工作流(workflow).

Usage

1. 打开 Automator, 选择新建一个 服务
2. Service receives selectd 选 text, in any application
3. 拖进来一个 Run Shell Script, Pass input 选择 stdin
4. 把下面这段 shell 脚本粘进去

#! /bin/bash

# stdin
input=""
while read line ; do input+=$line ; done

# exit if no input
# if [ $input="" ]; then
# 	exit 2
# fi

# get total length of input
# input_length=${#input}

# urlencode input
input=$(echo -ne ${input} | xxd -plain | tr -d '\n' | sed 's/\(..\)/%\1/g')

# static params
static_params="client=gtx&ie=UTF-8&oe=UTF-8&otf=2&ssel=0&tsel=3&kc=1"

# dt array of params
dt_array=("at" "bd" "ex" "ld" "md" "qca" "rw" "rm" "ss" "t")
for item in ${dt_array[@]};
do
  static_params+="&dt=$item"
done

# TODO: auto selct `tl`, `hl` and `sl`
dynamic_params="sl=auto&tl=zh-CN&hl=zh-CN"

curl --request GET \
  --url "https://translate.google.cn/translate_a/single?${static_params}&${dynamic_params}&q=${input}" \
  --header 'cache-control: no-cache' \
  --header 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36' \
  --header 'referer: https://translate.google.cn/?source=osdd'

5. 拖进来一个 Run JavaScript, 把下面这段 js 脚本粘进去

/**
 * filter json from google translate api
 *
 * @param {Array} json 
 * @returns
 */
function filter(json) {
  json = json || []

  var baseTranslate = json[0];

  var _pronunciation = baseTranslate.pop()[3] || '';
  var _source = '', _result = '';
  baseTranslate.forEach(function(item) {
    _result += item[0]
    _source += item[1];
  });

  var partsOfSpeech = json[1] || []
  var _pos = partsOfSpeech.map(function(item) {
    return {
      name: item[0],
      values: item[1]
    }
  })

  var listOfSpeech = json[11] || []
  var sentenceSamples = json[12] || []

  var _los = listOfSpeech.map(function(item) {
    return {
      name: item[0],
      values: item[1][0][0]
    }
  })
  var _ss = sentenceSamples.map(function(item) {
    return {
      name: item[0],
      value: item[1][0][0] + ' ' + item[1][0][2]
    }
  })

  return {
    pronunciation: _pronunciation,
    result: _result,
    source: _source,
    pos: _pos, // ?
    los: _los,
    ss: _ss
  }
}

/**
 * main function
 *
 * @param {String} input from shell
 * @param {any} parameters
 * @returns
 */
function run(input, parameters) {
  var resultJson;
  var splitLine = '—————————————————————————————';
  try {
    resultJson = JSON.parse(input);
  } catch (e) {
    return;
  }

  var filterdJson = filter(resultJson);
  var dialogText = '';

  dialogText += filterdJson.source + '  ';
  if (filterdJson.pronunciation) {
    dialogText += filterdJson.pronunciation + '\n';
  }
  dialogText += '\n' + splitLine + '\n';
  dialogText += '\n' + filterdJson.result + '\n';
  if (filterdJson.los.length !== 0) {
    dialogText += '\n' + splitLine + '\n源同义词:\n';
    filterdJson.los.forEach(function(item) {
      dialogText += '  ' + item.name + ' => ' + item.values.join(' ') + '\n';
    });
  }
  if (filterdJson.pos.length !== 0) {
    dialogText += '\n结果同义词:\n';
    filterdJson.pos.forEach(function(item) {
      dialogText += '  ' + item.name + ' => ' + item.values.join(' ') + '\n';
    });
  }
  if (filterdJson.ss.length !== 0) {
    dialogText += '\n例句:\n';
    filterdJson.ss.forEach(function(item) {
      dialogText += '  ' + item.name + ' => ' + item.value + '\n';
    });
  }

  var app = Application.currentApplication();
  app.includeStandardAdditions = true;

  app.displayDialog(
    dialogText,
    {
      buttons: ["打开网页", "确定"],
      defaultButton: "确定"
    }
  );
  return;
}

6. 打开 System Preferences => Keyboard => Shotcuts => Service => Text => Straw, 给它设置一个快捷键

Todo

1. 根据选中文字, 自动判断 source language 和 target language.
2. 打开网页 功能
