qu - has opinions on CLI programs so you don't have to!

Example

```rust use qu::ick_use::*; use std::path::PathBuf;

// This struct must not contain fields called verbose or quiet as these are used by qu.

[derive(Debug, StructOpt)]

struct Opt { #[structopt(parse(fromosstr))] file_name: PathBuf, }

// This function must contain exactly one argument that implements StructOpt, and should return // qu::ick_use::Result (although in reality your selected return type is ignored and // qu::ick_use::Result is always used). The body of th method is copied verbatim.

[qu::ick]

fn main(opt: Opt) -> Result { log::warn!("you'll see this unless you do -q"); log::info!( "(use -v to get info) selected file: {}", opt.file_name.display() ); Ok(()) } ```

Description

This crate contains the macro qu::ick that sets up argument parsing, logging and error handling with minimal boilerplate. It can do this because it decides for you what your configuration should be. If you need a different configuration I'd recommend copying out the generated code from the derive macro and tweaking it according to your needs.

Acknowledgements

This crate is based on quicli and most of the ideas are directly copied from that crate. quicli may be an alternative if you don't like the opinions this crate has.
