Sending keys
Pane.sendKeys sends Enter by default. Use enter: false to type without
submitting and literal: true when characters could be interpreted as key
names. Pass an abort signal to bound the operation.
Run the complete program¶
Capture pane output supplies the full TypeScript 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 returns captured lines. The complete program uses
AbortSignal.timeout for a deadline and matches a whole output line.
Its cleanup checks whether the private socket exists, including when startup
fails, and reports shutdown errors.
Where to go next¶
Capturing output covers the output side. Attaching to tmux connects to a server you already own.
