<p>Command Line Argument Parser written in Rust</p>
<p>A simply library for parsing command line arguments and subcommands when writing command line and console applications.</p>
<p>You can use <code>clap</code> to lay out a list of possible valid command line arguments and subcommands, then let <code>clap</code> parse the string given by the user at runtime.</p>
<p>When using <code>clap</code> you define a set of parameters and rules for your arguments and subcommands, then at runtime <code>clap</code> will determine their validity.</p>
<p><code>clap</code> also provides the traditional version and help switches &#39;for free&#39; by parsing the list of possible valid arguments lazily at runtime, and if not already defined by the developer <code>clap</code> will autogenerate all applicable &quot;help&quot; and &quot;version&quot; switches (as well as a &quot;help&quot; subcommand if other subcommands are defined as well).</p>
<p>After defining a list of possible valid arguments and subcommands, <code>clap</code> gives you a list of valid matches that the user supplied at runtime, or informs the user of their error and exits gracefully. You can use this list to determine the functioning of your program.</p>

<h2 id="installation-1" class='section-header'><a
href="#installation-1">Installation</a></h2>
<p>Add <code>clap</code> as a dependecy in your <code>Cargo.toml</code> file to use from crates.io:</p>
<pre id='rust-example-rendered' class='rust '>
[<span class='ident'>dependencies</span>]
<span class='ident'>clap</span> <span class='op'>=</span> <span class='string'>&quot;*&quot;</span>

<span class='ident'>git</span> <span class='op'>=</span> <span class='string'>&quot;https://github.com/kbknapp/clap-rs.git&quot;</span>
</pre>
<p>Then run <code>cargo build</code> or <code>cargo update</code> for your project.</p>
<h2 id="usage-1" class='section-header'><a

//!
//! ![Travis-CI](https://travis-ci.org/kbknapp/clap-rs.svg?branch=master)
//!
//! Command Line Argument Parser written in Rust
//!
//! A simply library for parsing command line arguments and subcommands when writing command line and console applications.
//!
//! You can use `clap` to lay out a list of possible valid command line arguments and subcommands, then let `clap` parse the string given by the user at runtime.
//!
//! When using `clap` you define a set of parameters and rules for your arguments and subcommands, then at runtime `clap` will determine their validity.
//!
//! `clap` also provides the traditional version and help switches 'for free' by parsing the list of possible valid arguments lazily at runtime, and if not already defined by the developer `clap` will autogenerate all applicable "help" and "version" switches (as well as a "help" subcommand if other subcommands are defined as well).
//!
//! After defining a list of possible valid arguments and subcommands, `clap` gives you a list of valid matches that the user supplied at runtime, or informs the user of their error and exits gracefully. You can use this list to determine the functioning of your program.
//!
//! ## Quick Example
//!
//! ```rust
//! // (Full example with comments in examples/01_QuickExample.rs)
//! extern crate clap;
//! use clap::{Arg, App, SubCommand};
//!
//! fn main() {
//! let matches = App::new("MyApp")
//! .version("1.0")
//! .author("Kevin K. <kbknapp@gmail.com>")
//! .about("Does awesome things")
//! .arg(Arg::new("config")
//! .short("c")
//! .long("config")
//! .help("Sets a custom config file")
//! .takes_value(true))
//! .arg(Arg::new("output")
//! .help("Sets an optional output file")
//! .index(1))
//! .arg(Arg::new("debug")
//! .short("d")
//! .multiple(true)
//! .help("Turn debugging information on"))
//! .subcommand(SubCommand::new("test")
//! .about("controls testing features")
//! .arg(Arg::new("verbose")
//! .short("v")
//! .help("print test information verbosely")))
//! .get_matches();
//!
//! if let Some(o) = matches.value_of("output") {
//! println!("Value for output: {}", o);
//! }
//!
//! if let Some(c) = matches.value_of("config") {
//! println!("Value for config: {}", c);
//! }
//!
//! match matches.occurrences_of("debug") {
//! 0 => println!("Debug mode is off"),
//! 1 => println!("Debug mode is kind of on"),
//! 2 => println!("Debug mode is on"),
//! 3 | _ => println!("Don't be crazy"),
//! }
//!
//! if let Some(ref matches) = matches.subcommand_matches("test") {
//! if matches.is_present("verbose") {
//! println!("Printing verbosely...");
//! } else {
//! println!("Printing normally...");
//! }
//! }
//!
//! // more porgram logic goes here...
//! }
//! ```
//!
//! If you were to compile the above program and run it with the flag `--help` or `-h` (or `help` subcommand, since we defined `test` as a subcommand) the following output woud be presented
//!
//! ```sh
//! $ myprog --help
//! MyApp 1.0
//! Kevin K. <kbknapp@gmail.com>
//! Does awesome things
//!
//! USAGE:
//! MyApp [FLAGS] [OPTIONS] [POSITIONAL] [SUBCOMMANDS]
//!
//! FLAGS:
//! -d Turn debugging information on
//! -h,--help Prints this message
//! -v,--version Prints version information
//!
//! OPTIONS:
//! -c,--config <config> Sets a custom config file
//!
//! POSITIONAL ARGUMENTS:
//! output Sets an optional output file
//!
//! SUBCOMMANDS:
//! help Prints this message
//! test Controls testing features
//! ```
//!
//! ## Installation
//! Add `clap` as a dependecy in your `Cargo.toml` file to use from crates.io:
//!
//! ```
//! [dependencies]
//! clap = "*"
//! ```
//! Or track the latest on the master branch at github:
//!
//! ```
//! [dependencies.clap]
//! git = "https://github.com/kbknapp/clap-rs.git"
//! ```
//!
//! Then run `cargo build` or `cargo update` for your project.
//!
//! ## Usage
//!
//! Add `extern crate clap;` to your crate root.
//!
//! ## More Information
//!
//! You can find complete documentation on the [github-pages site](http://kbknapp.github.io/clap-rs/docs/clap/index.html) for this project.
//!
//! You can also find full usage examples in the examples/ directory of this repo.
//!
//! ## How to build
//!
//! ### Running the tests
//!
//! ```
//! cargo test
//! ```
//!
//! ### Building the documentation
//!
//! Run this instead of `cargo doc` to generate the proper module docstring:
//!
//! ```
//! make doc
//! ```
