zigarg is a very light argument parser written fully in Rust. It's composed only of a small number but very helpful lines and lacks a lot of features but suitable for many applications, especially personal or small projects. It's also good for educational purposes as it isn't very complex.
I decided to publish the library after using it on several private CLI applications I made. I may add additional features in the future if I find it useful for my own projects as well.
Add zigarg to Cargo.toml as a dependency
[dependencies]
zigarg = "0.1.0"
Capture user's arguments by adding the code below, after you have added zigarg to your dependencies:
ignore
let arguments = zigarg::new();
Use the struct returned from zigarg::new() to perform different actions like the examples below
ignore
//Check if there are arguments provided by the user other than your program's name
let has_arguments = arguments.has_args();
//Check if the arguments provided by the user has a certain flag
let exist = arguments.exist("-q");
//Measure the number of arguments provided the user
let arguments_number = arguments.len();
//Get an argument from the arguments provided by the user via index number
let argument = arguments.get(1);
