使vte终端与运行的python脚本通信

使vte终端与运行的python脚本通信,python,gtk,pygtk,vte,Python,Gtk,Pygtk,Vte,我正在努力实现以下目标。我构建了一些gtk应用程序,其中包含一些数据,比如a、b和c 我现在想要的是某种终端窗口,在其中我可以像在iPython中一样查询和更改数据: $ a [1 2 3] $ a= a+1 $ a [2 3 4] 让它在gtk应用程序中生效。这是否可行?您可以尝试按子流程启动xterm,并在file.py和term之间进行通信,复制环境变量中的变量,然后通过以下方式获取: os.environ[your_var] 看看这个。一旦输入“python”。关于与脚本通信,我发

我正在努力实现以下目标。我构建了一些gtk应用程序,其中包含一些数据,比如a、b和c

我现在想要的是某种终端窗口,在其中我可以像在iPython中一样查询和更改数据:

$ a
[1 2 3]
$ a= a+1
$ a

[2 3 4]

让它在gtk应用程序中生效。这是否可行?

您可以尝试按子流程启动xterm,并在file.py和term之间进行通信,复制环境变量中的变量,然后通过以下方式获取:

os.environ[your_var]

看看这个。一旦输入“python”。关于与脚本通信,我发现的唯一方法是使用外部文件。你想要的是可能的,但很复杂。您有一个我制作的示例,其中我将变量“tty”从VTE终端返回到python脚本

from gi.repository import Gtk, GObject, Vte
#GObject is not required. I just import it everywhere just in case.
#Gtk, Vte, and GLib are required.
from gi.repository import GLib
import os
#os.environ['HOME'] helps to keep from hard coding the home string.
#os is not required unless you want that functionality.

你有自己的vte吗?嗨。我不太明白这个问题。我应该如何构建它?但总的来说,我对这些话题的经验很少,所以你的问题的答案可能是“不”。
