rparse

Description

Simple human-readable command-line argument parser.

Usage

rparse allows for users to build their own command-line arguments in the form of Argument structs in a vector array.

These are then passed alongside std::env::args() to a parsing module to check and fetch command-line arguments.

Example

``` use rparse::{parser, builder::Argument};

// Build arguments into a vector array fn build_arguments() -> Vec { let args: Vec = vec![ Argument::new("feeds", "--feed", "-f"), Argument::new("file", "--file", "-i"), ]; return args; }

fn main() {

// Build arguments
let args: Vec<Argument> = build_arguments();

// Fetch arguments passed to the program
let passed = std::env::args();

// Parse command-line arguments
let returned = parser::parse(args, passed).args;
println!("{:?}", returned["feeds"]);

} ```

Notes

parser::parse(args, passed) returns a ParsedArguments struct. This contains a HashMap of arguments found on the command line, referenced as args. To then access this, call the key from the HashMap: parser::parse(args, passed).args["key"].
