在 tkinter 中编辑后在两个文件之间同步数据

Question

我目前正在使用以下代码： https://github.com/yebrahim/pydiff 。 如果我们运行 pydiff.py，我们可以看到两个平面。 一个是左文件，其他代表右文件。 我们可以比较两个文件，它分别用红色和绿色突出显示差异。 如果我们相对于其他文件修改一个文件，它不会突出显示新的修改，即，如果我们修改任何文件，则不会定期进行同步。 样本：样本输入

完整代码可以在上面提到的 git 链接中找到。

    try:
        rightFileContents = open(self.rightFile).read()
    except:
        rightFileContents = ''

    diff = DifflibParser(leftFileContents.splitlines(), rightFileContents.splitlines())

            self.diff_files_into_text_areas()
    else:
        return None

在我们修改任何文本文件后，不知道如何进行同步。 我们可以将其作为默认检查是否有任何文件被修改。 有什么想法吗？
