Sending keys
Server.run(_:in:) types a command line and presses Enter. Await it with
try await, then wait separately for the output your next operation needs.
The complete program uses an explicit socket and propagates failed operations.
Run the complete program¶
Capture pane output supplies the full Swift 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.
Server.capture reads pane lines. The complete program compares a whole line,
bounds the wait and reports cleanup errors. For repeated reads of changing
output, the streaming APIs can track output beyond one screen snapshot;
consult this version’s API reference for their lifetime and completion rules.
Where to go next¶
Capturing output covers the output side. Attaching to tmux connects to a server you already own.
