cli-parser

Introduction

This library provides a very light-weight API, for a singular purpose: Collect the command line arguments in 3 std structures based on the number of dashes prefixed.

• Vector $\leftarrow$ 0 dashes $\leftarrow$ Positional arguments (values only).

• HashSet $\leftarrow$ 1 dash $\leftarrow$ Flags (keys only).

• HashMap $\leftarrow$ 2 dashes $\leftarrow$ Key - value pairs.

Syntax example:

./my_program --debug_level=2 -verb path/to/file 

These arguments are classified as:

• Positional:
  1. ./my_program
  2. path/to/file
• Flags:
  1. verb
• Pairs:
  1. debug_level with value 2

Usage

Just initialize the CLIParser struct and you are good to go.

use cliparser::CLIParser;


fn main() {

	// Initialize parser
	let parser = CLIParser::new().init().unwrap();
	
	// Extract parsed data structures
	let posit_arguments = parser.posits.clone(); // Vector
	let flags = parser.flags.clone(); // HashSet
	let pairs = parser.pairs.clone(); // HashMap
}
