Sending keys
Pane.send_keys accepts literal text with literal=True. It sends Enter by
default; use enter=False to type without submitting, then call Pane.enter.
The complete example sets literal mode explicitly.
Run the complete program¶
Capture pane output supplies the full Python 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_pane returns a list of lines. The complete program compares
whole lines, uses a monotonic deadline and closes its private server in
finally. The echoed shell command cannot satisfy its output check.
Where to go next¶
Capturing output covers the output side. Attaching to tmux connects to a server you already own.
