python实现sublime3的less编译插件示例

yipeiwu_com6年前 (2020-03-06)Python基础

利用http://tool.oschina.net/less 提供的接口,发送请求进行远程编译.
再将编译好的less,保存为同名后缀为css的文件中.
第一次使用python,代码也是拼拼凑凑的.需要加上线程进行异步请求,但是不会...

import sublime, sublime_plugin
import urllib
import json

class exampleCommand(sublime_plugin.TextCommand):
def run(self, edit):
  file_name=self.view.file_name();
  if file_name.find('.less') == -1:
   print('only .less file can compile to css!!');
   return;

  file_object_from = open(file_name);
  all_the_text = file_object_from.read();
  url = "http://tool.oschina.net/action/less/less_compile";
  data = all_the_text.encode(encoding='UTF8');

  headers = {'User-Agent':'sublime_plugin'};
  req = urllib.request.Request(url,data,headers);
  response = urllib.request.urlopen(req);
  the_page = response.read();
  css=json.loads(the_page.decode("utf8"))['css'];
  file_object_to = open(self.view.file_name().replace('.less', '.css'), 'w')
  file_object_to.write(css);

file_object_from.close();
file_object_to.close();

print(css);
