sargs

simple arg parsing in rust

sargs is a library that supplies a simple interface for building CLI applications.

Getting started

to get started with sargs just create a new Application:

use sargs::Application;
let app = Application::new("testapp", "this is a testapp");

An Application is the main wrapper around argument parsing. If you want your application to have an argument you can use .add_arg():

use sargs::Application;
use sargs::Argument;
use sargs::ArgumentKind;
let mut app = Application::new("testapp", "this is a testapp");
app.add_arg(Argument::new(ArgumentKind::Switch, "--version", "-v", "print the version", true));

Alternatively you can also create a new Application and supply the arguments as a vector with it:

use sargs::Application;
use sargs::Argument;
use sargs::ArgumentKind;
let mut app = Application::with_args("testapp", "a testapp", vec![Argument::new(ArgumentKind::Switch, "--help", "-h", "prints help", true), Argument::new(ArgumentKind::Switch, "--version", "-v", "prints the version", true), Argument::new(ArgumentKind::Value, "--url", "", "the url to request", false)]);

for the exact definition of the parameters for the functions see the documentation.
