如何在 libreoffice calc 中编写 python 宏来发送和接收数据

Question

前提：我在 libreoffice calc 中工作，需要通过宏向我知道正在侦听 TCP 端口的另一个程序发送指令。我期待监听程序的回复，并希望将回复数据插入到 libreoffice 电子表格中。

Answer 1

通过搜索 Whosebug 得到了多次帮助，我认为我会 post 解决一个需要很多努力才能解决的问题。该代码将数据拆分成行并插入到光标当前所在的单元格中，并且对于后续数据的每一行，都会增加下一次插入的行。

Configobj 是一个从平面文件中读取参数的包。在此示例中，我使用该文件来存储要使用的 TCP 端口。监听程序和这段代码都从同一个配置文件中读取端口号。它可能是硬编码的。

这是一个适合我的 python 宏，我相信它会为其他人指明正确的方向。
