在文本模式控制台 Emacs 会话中运行 Flymake 模式，我如何告诉 Flymake在文本控制台中显示其消息而不是尝试与 X 通信？
Emacs 23 在各种环境中运行，包括 Debian 和 Ubuntu。
我已经flymake-gui-warnings-enabled设置为nil，但是当我flymake-display-err-menu-for-current-line抱怨时：
X windows are not in use or not initialized
对我知道那个; Emacs 在没有 X 的情况下通过 SSH 连接运行。这就是我禁用 Flymake 使用 GUI 的原因。我如何告诉 Flymake不要尝试使用 GUI，而是在 Emacs 窗口中说出它必须说的话？
无论如何，我发现“工具提示”错误消息很烦人，所以我有这个在迷你缓冲区.emacs中显示flymake错误消息。这是我在某处从网上得到的东西。它被称为flymake-cursor.el。信用属于第一个写它的小伙子。您不需要特定于我用作 flymake 助手的 Python 工具的 pyflake 位。主要功能是show-fly-err-at-point允许您使用常规光标将鼠标悬停在突出显示的消息行上。

对早期解决方案的改进。使错误消息的行为更像 eldoc 消息。消息不会在消息缓冲区中结束，消息不会闪烁，并且消息不会阻塞其他输出。使用词法范围的变量而不是全局变量。
需要 emacs 24。我相信词法绑定注释必须放在文件的顶部。
我没有独立的存储库，但可以从我在 github 上的 emacs 配置中获得最新版本。

这里基本上是 Noufal Ibrahim 的答案，但 pyflakes 部分已被删除。更具体地说，我直接使用 flymake-ler-text 来提取错误的文本部分。我只尝试过epylint。奇迹般有效。

它有一些优化，以确保它不会在您高速光标时向您的迷你缓冲区发送垃圾邮件。
