Sending keys

Pane.SendTextAsync sends text; Pane.EnterAsync submits the line. Pass a cancellation token to both operations. The complete program performs these steps separately and waits for its output before treating the task as done.

Run the complete program¶

Capture pane output supplies the full C# program, imports, project setup and run command. It starts a private server, sends a command, checks a complete output line and cleans up.

Literal text, key names, and whether Enter follows¶

Choose the method and options for the input you mean to send. Literal text still goes to an application: a shell interprets its quoting, expansions and commands. Key-name handling and shell interpretation are separate concerns.

The race you can’t see from the call site¶

A successful send means tmux accepted input. The pane’s program may still be starting or processing that input. Wait for the state the next operation needs. Terminal echo alone does not prove command completion.

Pane.CaptureAsync reads visible pane lines. The complete program passes a cancellation token, compares whole lines and bounds its waits with a CancellationTokenSource. Its OwnedServerScope owns the private server and is disposed with await using.

Where to go next¶

Capturing output covers the output side. Attaching to tmux connects to a server you already own.
