Expand description

Define custom keybindings

This trait can help define custom keybindings in case the downsteam applications aren’t satisfied with the defaults

Please do note that, in order to match the keybindings, you need to directly work with the underlying crossterm crate

Example

use minus::{input::{InputEvent, InputClassifier}, LineNumbers, Pager, PagerState};
use minus::SearchMode;
use crossterm::event::{Event, KeyEvent, KeyCode, KeyModifiers};

struct CustomInputClassifier;
impl InputClassifier for CustomInputClassifier {
    fn classify_input(
        &self,
        ev: Event,
        ps: &PagerState
    ) -> Option<InputEvent> {
            match ev {
                Event::Key(KeyEvent {
                    code: KeyCode::Up,
                    modifiers: KeyModifiers::NONE,
                })
                | Event::Key(KeyEvent {
                    code: KeyCode::Char('j'),
                    modifiers: KeyModifiers::NONE,
                }) => Some(InputEvent::UpdateUpperMark
                      (ps.upper_mark.saturating_sub(1))),
                _ => None
        }
    }
}

let mut pager = Pager::new();
pager.set_input_classifier(
                Box::new(CustomInputClassifier)
            );
