Crate appcore_args 

appcore-args

Português | Français

Dependency-free, cross-platform command-line parsing, help, validation and shell completion primitives for AppCore executables.

appcore-args provides nested commands, inherited options, typed and bounded arguments, deterministic errors, generated help, completion candidates and dynamic completion scripts for Bash, Zsh, Fish and PowerShell. It executes no Runtime behavior and uses no unsafe code.

use appcore_args::{ArgumentSpec, CliParser, CliSpec, CommandSpec, OptionSpec, RawArgs};

let spec = CliSpec::new("demo")
    .option(OptionSpec::flag("verbose").short('v'))
    .command(CommandSpec::new("run").argument(
        ArgumentSpec::new("mode").required(true).possible_value("safe"),
    ));
let parsed = CliParser::new(&spec)
    .parse(&RawArgs::parse(["run", "safe", "-v"])? )?;

assert_eq!(parsed.command_path(), &["run"]);
assert!(parsed.has_flag("verbose"));
