clio

clio is a rust library for parsing CLI file names.

It implements the standard unix conventions of when the file name is - then sending the data to stdin/stdout

// a cat replacement
fn main() -> clio::Result<()> {
    let args: Vec<_> = std::env::args_os().collect();
    let mut input = clio::Input::new(&args[1])?;
    std::io::copy(&mut input, &mut std::io::stdout())?;
    Ok(())
}
