linux下方便的使用有道词典

这里写图片描述
直接上图，觉得合适就用，想查单词时，复制单词粘贴到终端，非常方便。不要骗自己说你想知道音标，想知道详细的例句，大多时候我们是只需要快速知道这个单词的意思。实现方法是大牛实现的，使用python调用有道的接口，但我忘记出处了，抱歉！
我也折腾过有道词典的安装，后来安装好了，但体验非常差，之前是占用资源巨多，后来换了个高配的笔记本，还是感觉不好用。奉劝在折腾的同学一句，不要在折腾有道词典的安装。ubuntu上安装还挺方便的，centos上安装这词典真心不容易。我现在直接使用终端查单词，浏览器直接使用有道的翻译插件。挺方便的！
youdao终端查单词其实很简单，就几行python代码，我直接贴上来吧，复制代码并在/usr/local/bin下建个可执行文件就可以使用了。

sudo gedit  /usr/local/bin/dict.py

粘贴代码：

    #! /usr/bin/python  import re;  import urllib;  import urllib2;  import sys;  def debug():      xml = open("word.xml").read();      print get_text(xml);      print get_elements_by_path(xml, "custom-translation/content");      #print_translations(xml, False, False);  def get_elements_by_path(xml, elem):      if type(xml) == type(''):          xml = [xml];      if type(elem) == type(''):          elem = elem.split('/');      if (len(xml) == 0):          return [];      elif (len(elem) == 0):          return xml;      elif (len(elem) == 1):          result = [];          for item in xml:              result += get_elements(item, elem[0]);          return result;      else:          subitems = [];          for item in xml:              subitems += get_elements(item, elem[0]);          return get_elements_by_path(subitems, elem[1:]);  textre = re.compile("<\!\[CDATA\[(.*?)\]\]", re.DOTALL);  def get_text(xml):      #print 10*"..."+"\n"    match = re.search(textre, xml);      if not match:          return xml;      #print 40*"..."    #print match    #print 40*"..."    return match.group(1);  def get_elements(xml, elem):      p = re.compile("<" + elem + ">" + "(.*?)</" + elem + ">", re.DOTALL);      it = p.finditer(xml);      result = [];      for m in it:          result.append(m.group(1));      return result;  GREEN = "\033[1;32m";  DEFAULT = "\033[0;49m";  BOLD = "\033[1m";  UNDERLINE = "\033[4m";  NORMAL = "\033[m";  RED = "\033[1;31m"  def crawl_xml(queryword):      return urllib2.urlopen("http://dict.yodao.com/search?keyfrom=dict.python&q=" + urllib.quote_plus(queryword) + "&xmlDetail=true&doctype=xml").read();  def print_translations(xml, with_color, detailed):      #print xml;      original_query = get_elements(xml, "original-query");      queryword = get_text(original_query[0]);      custom_translations = get_elements(xml, "custom-translation");      print BOLD + UNDERLINE + queryword + NORMAL;      translated = False;      for cus in custom_translations:          source = get_elements_by_path(cus, "source/name");          print RED + "Translations from " + source[0] + DEFAULT;          contents = get_elements_by_path(cus, "translation/content");          if with_color:              for content in contents[0:5]:                  print GREEN + get_text(content) + DEFAULT;          else:              for content in contents[0:5]:                  print get_text(content);          translated = True;      yodao_translations = get_elements(xml, "yodao-web-dict");      printed = False;      for trans in yodao_translations:          webtrans = get_elements(trans, "web-translation");          for web in webtrans[0:5]:              if not printed:                  print RED + "Translations from yodao:" + DEFAULT;                  printed = True;                  keys = get_elements(web, "key");              values = get_elements_by_path(web, "trans/value");              summaries = get_elements_by_path(web, "trans/summary");              key = keys[0].strip();              value = values[0].strip();              #summary = summaries[0].strip();                  #lines = get_elements(summary, "line");              if with_color:                  print BOLD +  get_text(key) + ":\t" +DEFAULT + GREEN + get_text(value) + NORMAL;                  #for line in lines:                  #    print GREEN + get_text(line) + DEFAULT;                  #print get_text(summary) + DEFAULT;              else:                  print get_text(value);                  #print get_text(summary);                      #translated = True;                      #if not detailed:                      #        break  def usage():      print "usage: dict.py word_to_translate";  def main(argv):      if len(argv) <= 0:          usage();          #debug();          sys.exit(1);      xml = crawl_xml("".join(argv));      print_translations(xml, True, False);      #print_translations(xml, True, True);      #print_translations(xml, False, False);  if __name__ == "__main__":      main(sys.argv[1:]);

gedit /usr/local/bin/youdao
粘贴如下代码：

#!/bin/bashpython /usr/local/bin/dict.py $1;echo -n "input:";while read input;do    python /usr/local/bin/dict.py ${input};    echo -n "input:";done

最后一步，给文件添加可执行权限：

 sudo chmod + x /usr/local/bin/dict.py sudo chmod + x /usr/local/bin/youdao

随便打开一个终端做个测试,输入:

youdao  english

看是不是可以正常查词啦！
祝好运！！
