Peek at input

[coz-eduardo-hernandez]

Would it be possible to have a function similar to notcurses_get* that peeks at the input, but doesn't remove the input from the event list? So i you call notcurses_get* you'd get the same input.

Maybe also function that removes the next event without getting it (if that allows a function that does less work), since you might have handled the event when peaked at.

The purpose is being able to pass events in a manner similar to many UI systems; the top layer widget receives the input, then passes it down until a widget that can handle the input is reached. However if the last widget is reached and the event hasn't been handled yet, a default handler could do whatever it needs to, maybe handle it or just discard the event from the queue. The default handler should be able to be in a module that's separated from the widgets.

This might be done portably by calling ungetc() on stdin.
