#!python3 #运行 py mcb.pyw save spam ，剪贴板内容就关键字spam保存 #py mcb.pyw spam 加载spam 对应内容到剪贴板 #py mcb.pyw list 关键字列表到剪贴板 #扩展多重剪贴板： #增加delete <keyword>，从shelf中删除相应键值 #delete all 清空 import sys,pyperclip,shelve mcbShelf=shelve.open(r'I:\mcb') #save clipboasr content: if len(sys.argv) == 3: if sys.argv[1].lower()=='save' and sys.argv[2].lower() != 'all': mcbShelf[sys.argv[2]] = pyperclip.paste() elif sys.argv[1].lower()=='delete' and sys.argv[2].lower()=='all': mcbShelf.clear() elif sys.argv[1].lower()=='delete' and sys.argv[2] in mcbShelf: del mcbShelf[sys.argv[2]] elif len(sys.argv) == 2: #List keywords and load content. if sys.argv[1]=='list': pyperclip.copy(str(list(mcbShelf.keys()))) elif sys.argv[1] in mcbShelf: pyperclip.copy(mcbShelf[sys.argv[1]]) else: print("参数错误") else: print('wrong') mcbShelf.close()
