Sending keys
Pass a tmux.SendKeysRequest to Pane.SendKeys and check the returned error.
Set Literal to send characters and SkipEnter to type without submitting.
Pane.Enter sends Enter separately. Use a context deadline for operations that
must finish within a fixed budget.
Run the complete program¶
Capture pane output supplies the full Go 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.Capture takes a tmux.CapturePaneRequest. Use Start and End to choose
a range; tmux.CaptureBoundary reaches the corresponding history or screen
boundary. The complete program reads the visible screen, compares full lines
and stops when its context expires.
Where to go next¶
Capturing output covers the output side. Attaching to tmux connects to a server you already own.
