# Sing

Std
I/o
Negotiator
Generator

## What is sing meant to be?

- Provide stdio interface to traits
- not like serde because it's for traits instead of objects
- not like clap since it works at run time, not before
- similar ease of use as both of the above though

## How to get there

- Using lalrpop (in a feature flag)
- Maybe utilize serde
- Look at how clap handles states between macro calls
  - They operate on a singleton lol
  	 - We should, too
	 - Providing both a builder and derive interface makes sense
	 - Needs a list of traits and one for functions
	 - latter one should be created from the first with a macro
	 - should provide a method to match a call to these functions
	 - It should also own (locked) Stdin, Stdout and Stderr (or any one Read and two Write objects)
