Signal channel¶

`signal_channel`¶

signal_channel

signal_channel

Signal a tmux wait-for channel, waking blocked waiters.

Returns:: str

Use when you need to wake a blocked wait_for_channel caller from a different MCP context (e.g. when a long-running task in one pane completes and another pane should proceed). With no current waiter, tmux records one pending signal for the next waiter. A second signal before that wait clears the channel.

Side effects: Wakes clients blocked on the named channel or records one pending signal for the next waiter to consume. A waiter resumes whatever work follows its wait.
