[Idea] replace fzf support with skim library

[Th3Whit3Wolf]

The skim binary is as far as I could tell a direct drop-in replacement for fzf built with rust. I have never used their library but their example on their README

# Cargo.toml
[dependencies]
skim = "0.7.0"

extern crate skim;
use skim::prelude::*;
use std::io::Cursor;

pub fn main() {
    let options = SkimOptionsBuilder::default()
        .height(Some("50%"))
        .multi(true)
        .build()
        .unwrap();

    let input = "aaaaa\nbbbb\nccc".to_string();

    // `SkimItemReader` is a helper to turn any `BufRead` into a stream of `SkimItem`
    // `SkimItem` was implemented for `AsRef<str>` by default
    let item_reader = SkimItemReader::default();
    let items = item_reader.of_bufread(Cursor::new(input));

    // `run_with` would read and show items from the stream
    let selected_items = Skim::run_with(&options, Some(items))
        .map(|out| out.selected_items)
        .unwrap_or_else(|| Vec::new());

    for item in selected_items.iter() {
        print!("{}: {}{}", item.get_index(), item.get_output_text(), "\n");
    }
}

seems simple enough.

This definitely looks interesting, I will give this a try!

The only issue with this is that currently, zoxide is cross-platform. However, tui-rs (made by the @lotabout, the creator of skim to dogfood FOR skim) is *nix-only, and the author has preferred not to take the time to make sure it works with Windows.

[ajeetdsouza]

While zoxide currently only supports *nix, I do intend to eventually add Windows support. If skim worsens the gap, it must be counted out.

Thanks!

skim is also much slower than fzf.

Yes, but it's not noticible unless you have lots and lots of files.
