The best README is probably the test cases:

#[test]
fn it_works() {
    assert_eq!(tico("~"), "~");
    assert_eq!(tico("/"), "/");
    assert_eq!(tico("/home/hugopeixoto/work/personal/tico"), "/h/h/w/p/tico");
    assert_eq!(tico("~/work/personal/tico"), "~/w/p/tico");
    assert_eq!(tico("~/work/personal/tico/"), "~/w/p/t/");
    assert_eq!(tico("~/work/ééé/tico"), "~/w/é/tico");
}

Install

$ cargo install --git [email protected]:portocodes/tico.git

Use

Here's how I'm using it in fish_prompt.fish to replace prompt_pwd:

set -l cwd $cyan(tico (echo $PWD | sed -e "s|^$HOME|~|"))
