'SIGINT' 事件
每当 input
流接收到 Ctrl+C 输入(通常称为 SIGINT
)时,则会触发 'SIGINT'
事件。
如果在 input
流接收到 SIGINT
时没有注册 'SIGINT'
事件监听器,则将触发 'pause'
事件。
调用监听器函数时不传入任何参数。
rl.on('SIGINT', () => {
rl.question('Are you sure you want to exit? ', (answer) => {
if (answer.match(/^y(es)?$/i)) rl.pause();
});
});
The 'SIGINT'
event is emitted whenever the input
stream receives a
Ctrl+C input, known typically as SIGINT
. If there are no 'SIGINT'
event listeners registered when the input
stream receives a SIGINT
, the
'pause'
event will be emitted.
The listener function is invoked without passing any arguments.
rl.on('SIGINT', () => {
rl.question('Are you sure you want to exit? ', (answer) => {
if (answer.match(/^y(es)?$/i)) rl.pause();
});
});
