[Feature]: Feature request: SSH connection status indicator in terminal tab

[robindiy]

Feature description

功能建议：SSH 连接状态指示

当前使用场景：

• 在 Wave 中打开本地终端，通过 ssh user@host 连接远程服务器。
• Wave 右侧终端面板会显示“running command 'ssh ...'”。
• 现在要判断连接是否还活跃，只能通过：
  • 看提示符是不是远程的 user@host:~#，
  • 或者按回车，看有没有响应，
  • 或自己写一个循环 echo 的“心跳”命令。

问题：

• 对于长时间挂着的 SSH 会话，很难一眼判断“这条 SSH 连接现在到底还在不在”。
• SSH 进程有时会因为网络问题卡死，看上去还在“running”，但实际上连接已经不可用，需要用户自己再去测试。
• 对新用户来说，不太直观。

Current usage:

• Using a local terminal in Wave and connecting to a remote server via ssh user@host.
• The terminal widget shows running command "ssh ..." on the header.
• To check whether the SSH connection is still alive, I currently have to:
  • Look at the prompt (user@host:~# vs local prompt),
  • Press Enter and see if there is a response, or
  • Run a custom “heartbeat” loop that periodically echos something.

Problems:

• For long‑running SSH sessions, it’s not obvious at a glance whether the SSH connection is still active.
• Sometimes the ssh process can hang due to network issues: the process is still “running”, but the connection is effectively dead, which requires manual testing by the user.
• This is not very intuitive, especially for less experienced users.

Implementation Suggestion

我现在没法直接把反馈“发”给 Wave 团队，但可以帮你写一份比较完整的需求描述，你可以复制后：

• 发到你拿到 Wave 的渠道（Slack、Github issues、邮件等），或者
• 以后如果 Wave 内置反馈入口，也可以直接贴进去。

你可以用下面这段（中英文都给你）：

功能建议：SSH 连接状态指示

当前使用场景：

• 在 Wave 中打开本地终端，通过 ssh user@host 连接远程服务器。
• Wave 右侧终端面板会显示“running command 'ssh ...'”。
• 现在要判断连接是否还活跃，只能通过：
  • 看提示符是不是远程的 user@host:~#，

• SSH 进程有时会因为网络问题卡死，看上去还在“running”，但实际上连接已经不可用，需要用户自己再去测试。
• 对新用户来说，不太直观。

期望的功能：

1. 在终端 tab 或终端 header 显示更直观的 SSH 状态，比如：
   • “SSH: connected” / “SSH: disconnected”
   • 或在 tab 名上加一个小图标（绿色/灰色）表示连接状态。
2. 当检测到 SSH 进程退出或连接断开时：
   • 有一个非打扰式提示（例如在终端顶部显示一行 “SSH connection to host closed”）。
     3.（可选）如果可能的话，对常见 ssh 命令做轻量识别（如 ssh user@host），自动给这个 tab 打上“SSH to host”标签，方便区分不同服务器的会话。

这样可以提升：

• 长时间运维、调试远程服务时的可视性；
• 初级用户判断“我现在是在本机还是远程机上”的清晰度；
• 快速定位连接何时断开，而不需要靠手动尝试命令。

当前环境：

• Local Machine: macOS 15.7.3 (arm64), User: robin
• Open Widget: local CLI terminal (zsh 5.9), running command ssh root@163.7.2.196, in /Users/robin.

Feature request: SSH connection status indicator

Current usage:

• Using a local terminal in Wave and connecting to a remote server via ssh user@host.
• The terminal widget shows running command "ssh ..." on the header.
• To check whether the SSH connection is still alive, I currently have to:
  • Look at the prompt (user@host:~# vs local prompt),
  • Press Enter and see if there is a response, or
  • Run a custom “heartbeat” loop that periodically echos something.

Problems:

• For long‑running SSH sessions, it’s not obvious at a glance whether the SSH connection is still active.
• Sometimes the ssh process can hang due to network issues: the process is still “running”, but the connection is effectively dead, which requires manual testing by the user.
• This is not very intuitive, especially for less experienced users.

Requested behavior:

1. Show a more explicit SSH status on the terminal tab or header, e.g.:
   • “SSH: connected” / “SSH: disconnected”, or
   • a small colored icon (green/gray) to indicate connection state.
2. When the SSH process exits or the connection is closed:
   • display a non-intrusive notice like “SSH connection to host closed” in the terminal header.
3. (Optional) If feasible, lightly detect common ssh commands (like ssh user@host) and automatically tag that tab as “SSH to host” to distinguish different remote sessions.

Benefits:

• Better visibility for long‑running remote debugging / operations sessions.
• Clearer indication for whether I’m on the local machine or a remote host.
• Easier to see when/if a connection has dropped without having to run extra commands.

Current environment:

• Local Machine: macOS 15.7.3 (arm64), User: robin
• Widget: local CLI terminal (zsh 5.9), running ssh root@163.7.2.196 in /Users/robin.

你可以根据自己习惯稍微改两句，然后直接发给你那边的 Wave 渠道就行。需要我帮你缩短成一两句话版的，也可以说。

Anything else?

You should use Wave's built-in SSH connection switcher. That will manage your SSH connections, show when disconnected, and detect network stalls. You can also run durable sessions through them (that will reconnect seamlessly if your network drops).

Wave's SSH system also allows for running "wsh" commands, file previews, file transfers, and file editing.

Given all those features are built in if you use Wave's ssh system, we won't be making any fixes in the manual ssh flow. In fact, when running "ssh" manually, the terminal doesn't have any special knowledge of the connection (other than the "ssh" command is still running -- what you see in the header). The internals of the connection state are all managed by the "ssh" program itself. This is one of the reasons why we built Wave's connection feature in the first place, to expose more of that state and allow the terminal to manage the connection.
