configuration file for setting keybindings

[arbiter0xf]

Read keybindings from a .toml file.

Motivation was to just provide vimlike keybinds, but using a configuration file does serve a broader range of users.

Issue currently in progress, so please assign ticket to me if appropriate.

Noticed that a logfile may be handy. It seems to me that when ncurses clears terminal content in endwin(), this also gets rid of any prints.

Could make another issue for this.

I thought that support for reading .toml files would be builtin somehow. It is not. toml crate has a dependency to serde_derive::Deserialize, so not liking this approach as much anymore. Will implement anyways, and see how it looks when done.

@arbiter0xf IMHO, this needs refactoring. All actions inside getch handling should have it's own names in order to refer to them. Looks like some sort of an API required.

BTW, it feels like @rexim follows suckless approach and simply injecting "config" source code into match body seams fine enough (via std::include!)

srs/main.rs

let nav_up = || match panel {
    Status::Todo => list_up(&mut todo_curr),
    Status::Done => list_up(&mut done_curr),
};
// other API lambda functions
// ...
let key = getch();
match key as u8 as char {
    include!("keys-config.rs")
}

src/keys-config.rs

'k' => nav_up(),
// handling other input
