A way to print simple lint messages.

The output is similar to rustc's.

lib.rs:

A library for pretty-printing lint errors with a given source text.

The API is fairly minimal, and the output closely resembles rustc's.

Example usage:

let src = "highlight me";

let lint = PrettyLint::success(src)
            .at(Span::range((1, 1), (1, src.len())))
            .with_message("you have been highlighted")
            .with_inline_message("look at this")
            .with_file_path(file!());

println!("{}", lint);
