parse_arguments_rs

Easy way to deal with parsing commandline arguments

Can be used with any type that implements FromStr (for parsing). Use parse_argument() function to find a value for a specified key (flag). Look at the examples for an idea of how to use it. It works for arguments that look like this: 

./rust_code --setting=foo --num=42 --hello="world"

And to retrieve those values you would write:

let _ = parse_argument::<Setting>("option").unwrap().unwrap();
let _ = parse_argument::<i32>("num").unwrap().unwrap();
let _ = parse_argument::<String>("hello").unwrap().unwrap();

Run cargo doc --open to see the documentation.

TODO

  • the key nor the value can have any spaces because of the nature of std::env::args. I will try to fix it at some point.
  • Make a function that returns a hashmap of all the arguments with their key and value

Enums

Functions

  • parse_argument
    Takes an argument flag, and a type (generally with turbofish syntax). Will look for any arguments in std::env::args that contains --{flag}=. Then it will split it and try to parse it.
