It's inspired +by python's ``argparse`` module. + +Features: + +* Supports standard (GNU) option conventions +* Properly typed values +* Automatically generated help and usage messages + +Importing +========= +Edit your Cargo.toml to add ``rust-argparse`` to your project. + +.. code-block:: rust + + [dependencies] + argparse = "0.2.2" + + +Example +======= + +The following code is a simple Rust program with command-line arguments: + +.. code-block:: rust + + extern crate argparse; + + use argparse::{ArgumentParser, StoreTrue, Store}; + + fn main() { + let mut verbose = false; + let mut name = "World".to_string(); + { // this block limits scope of borrows by ap.refer() method + let mut ap = ArgumentParser::new(); + ap.set_description("Greet somebody."); + ap.refer(&mut verbose) + .add_option(&["-v", "--verbose"], StoreTrue, + "Be verbose"); + ap.refer(&mut name) + .add_option(&["--name"], Store, + "Name for the greeting"); + ap.parse_args_or_exit(); + } + + if verbose { + println!("name is {}", name); + } + println!("Hello {}!", name); + } + +Assuming the Rust code above is saved into a file ``greeting.rs``, let's see +what we have now:: + + $ rustc greeting.rs + $ ./greeting -h + Usage: + ./greeting [OPTIONS] + + Greet somebody. + + Optional arguments: + -h, --help Show this help message and exit + -v, --verbose + Be verbose + --name NAME Name for the greeting + $ ./greeting + Hello World! + $ ./greeting --name Bob + Hello Bob! + $ ./greeting -v --name Alice + name is Alice + Hello Alice! + + +Basic Workflow +============== + + +Create ArgumentParser +--------------------- + +The argument parser is created empty and is built incrementally. So we create +a mutable variable:: + + extern crate argparse; + use argparse::ArgumentParser; + + let mut parser = ArgumentParser::new(); + + +Customize +--------- + +There are optional customization methods. The most important one is:: + + parser.set_description("My command-line utility") + +The descripion is rewrapped to fit 80 column string nicely. Just like option +descriptions. + +Add Options +----------- + +The ``refer`` method creates a cell variable, which the result will be written +to:: + + let mut verbose = false; + parser.refer(&mut verbose); + +Next we add an options which control the variable: +For example:: + + parser.refer(&mut verbose) + .add_option(&["-v", "--verbose"], StoreTrue, + "Be verbose"); + +You may add multiple options for the same variable:: + + parser.refer(&mut verbose) + .add_option(&["-v", "--verbose"], StoreTrue, + "Be verbose") + .add_option(&["-q", "--quiet"], StoreFalse, + "Be verbose"); + +Similarly positional arguments are added:: + + let mut command = String; + parser.refer(&mut command) + .add_argument("command", Store, + "Command to run"); + + + +Organizing Options +------------------ + +It's often useful to organize options into some kind of structure. You can +easily borrow variables from the structure into option parser. For example:: + + struct Options { + verbose: bool, + } + ... + let mut options = Options { verbose: false }; + parser.refer(&mut options.verbose) + .add_option(&["-v"], StoreTrue, + "Be verbose"); + + +Parsing Arguments +----------------- + +All the complex work is done in ``parser.parse_args()``. But there is +a simpler option:: + + parser.parse_args_or_exit() + +In case you don't want argparse to exit itself, you might use the +``parse_args`` function directly:: + + use std::process::exit; + + match parser.parse_args() { + Ok(()) => {} + Err(x) => { + std::process::exit(x); + } + } + + +ArgumentParser Methods +====================== + +``parser.refer<T>(var: &mut T) -> Ref`` + Attach the variable to argument parser. The options are added to the + returned ``Ref`` object and modify a variable passed to the method. + +``parser.add_option(names: &[&str], action: TypedAction, help: &str)`` + Add a single option which has no parameters. Most options must be added + by ``refer(..)`` and methods on ``Ref`` object (see below). + + Example:: + + ap.add_option(&["-V", "--version"], + Print(env!("CARGO_PKG_VERSION").to_string()), "Show version"); + +``parser.set_description(descr: &str)`` + Set description that is at the top of help message. + +``parser.stop_on_first_argument(val: bool)`` + If called with ``true``, parser will stop searching for options when first + non-option (the one doesn't start with ``-``) argument is encountered. This + is useful if you want to parse following options with another argparser or + external program. + +``parser.silence_double_dash(val: bool)`` + If called with ``true`` (default), parser will not treat *first* double + dash ``--`` as positional argument. Use ``false`` if you need to add some + meaning to the ``--`` marker. + +``parser.print_usage(name: &str, writer: &mut Write)`` + Prints usage string to stderr. + +``parser.print_help(name: &str, writer: &mut Write)`` + Writes help to ``writer``, used by ``--help`` option internally. + +``parser.parse_args()`` + Method that does all the dirty work. And returns ``Result`` + +``parser.parse_args_or_exit()`` + Method that does all the dirty work. And in case of failure just ``exit()`` + + +Variable Reference Methods +========================== + +The ``argparse::Ref`` object is returned from ``parser.refer()``. +The following methods are used to add and customize arguments: + +``option.add_option(names: &[&str], action: TypedAction, help: &str)`` + Add an option. All items in names should be either in format ``-X`` or + ``--long-option`` (i.e. one dash and one char or two dashes and long name). + How this option will be interpreted and whether it will have an argument + dependes on the action. See below list of actions. + +``option.add_argument(name: &str, action: TypedAction, help: &str)`` + Add a positional argument + +``option.metavar(var: &str)`` + A name of the argument in usage messages (for options having argument). + +``option.envvar(var: &str)`` + A name of the environment variable to get option value from. The value + would be parsed with ``FromStr::from_str``, just like an option having + ``Store`` action. + +``option.required()`` + The option or argument is required (it's optional by default). If multiple + options or multiple arguments are defined for this reference at least one + of them is required. + + +Actions +======= + +The following actions are available out of the box. They may be used in either +``add_option`` or ``add_argument``: + +``Store`` + An option has single argument. Stores a value from command-line in a + variable. Any type that has the ``FromStr`` and ``Clone`` traits implemented + may be used. + +``StoreOption`` + As ``Store``, but wrap value with ``Some`` for use with ``Option``. For + example: + + let mut x: Option<i32> = None; + ap.refer(&mut x).add_option(&["-x"], StoreOption, "Set var x"); + +``StoreConst(value)`` + An option has no arguments. Store a hard-coded ``value`` into variable, + when specified. Any type with the ``Clone`` trait implemented may be used. + +``PushConst(value)`` + An option has no arguments. Push a hard-coded ``value`` into variable, + when specified. Any type which has the ``Clone`` type implemented may be + used. Option might used for a list of operations to perform, when ``required`` + is set for this variable, at least one operation is required. + +``StoreTrue`` + Stores boolean ``true`` value in a variable. + (shortcut for ``StoreConst(true)``) + +``StoreFalse`` + Stores boolean ``false`` value in a variable. + (shortcut for ``StoreConst(false)``) + + +``IncrBy(num)`` + An option has no arguments. Increments the value stored in a variable by a + value ``num``. Any type which has the ``Add`` and ``Clone`` traits may be used. + +``DecrBy(nym)`` + Decrements the value stored in a variable by a value ``num``. Any type + which has the ``Add`` and ``Clone`` traits may be used. + +``Collect`` + When used for an ``--option``, requires single argument. When used for a + positional argument consumes all remaining arguments. Parsed options are + added to the list. I.e. a ``Collect`` action requires a + ``Vec<int>`` variable. Parses arguments using ``FromStr`` trait. + +``List`` + When used for positional argument, works the same as ``List``. When used + as an option, consumes all remaining arguments. + + Note the usage of ``List`` is strongly discouraged, because of complex + rules below. Use ``Collect`` and positional options if possible. But usage + of ``List`` action may be useful if you need shell expansion of anything + other than last positional argument. + + Let's learn rules by example. For the next options:: + + ap.refer(&mut lst1).add_option(&["-X", "--xx"], List, "List1"); + ap.refer(&mut lst2).add_argument("yy", List, "List2"); + + The following command line:: + + ./run 1 2 3 -X 4 5 6 + + Will return ``[1, 2, 3]`` in the ``lst1`` and the ``[4,5,6]`` in the + ``lst2``. + + Note that using when using ``=`` or equivalent short option mode, the + 'consume all' mode is not enabled. I.e. in the following command-line:: + + ./run 1 2 -X3 4 --xx=5 6 + + The ``lst1`` has ``[3, 5]`` and ``lst2`` has ``[1, 2, 4, 6]``. + The argument consuming also stops on ``--`` or the next option:: + + ./run: -X 1 2 3 -- 4 5 6 + ./run: -X 1 2 --xx=3 4 5 6 + + Both of the above parse ``[4, 5, 6]`` as ``lst1`` and + the ``[1, 2, 3]`` as the ``lst2``. + +``Print(value)`` + Print the text and exit (with status ``0``).
