Struct TerminalPresenter 

pub struct TerminalPresenter { /* private fields */ }

Terminal presenter adapter

Renders command output to the terminal. In text mode, all output goes to stdout. In JSON mode, messages go to stderr and artifacts are serialized as JSON to stdout. This follows the convention used by gh, kubectl, and jq.

The presenter also asks the user the questions of the command. It writes a question to stderr in both modes, and the user answers with one line on stdin. Verbosity and output mode do not suppress a question. A presenter that is not built as interactive drops every question.

TerminalPresenter is constructed once via its builder, consumed by a single call to present, and dropped when the command completes. The presenter holds the EventReceiver alive during command execution so that EventSenders do not receive errors when sending. After the command completes, the presenter and its receiver are dropped.

Examples

use clawless_core::event::event_channel;
use clawless_cli::presenter::TerminalPresenter;

let (_sender, receiver) = event_channel();
let presenter = TerminalPresenter::builder().receiver(receiver).build();
