= CLI Arg Parser

:source-highlighter: pygments

:icons: font

A clumsy and inconvenient CLI argument parser written in D.

== Features

* Short flags `-f`

** With optional values `-f [value]`

** With mandatory values `-f `

** That can be specified multiple times `-f -f -fff`

* Long flags `--foo`

** With optional values `--foo[=value]`

** With mandatory values `--foo=`

** That can be specified multiple times `--foo --foo -ff --foo`

* Positional parameters

import std.stdio;

import eph.args;

void main(const string[] args)

{

  Argument  count = new Argument().shortFlag('c');

  Argument  flag  = new Argument().longFlag("flag").shortFlag('f').requireParam();

  Parameter param = new Parameter();

  ArgParser parse = new ArgParser().register(count, flag).register(param);

  parse.parse(args);

  writefln("count: %d", count.uses());

  writefln("flag: %s", flag.values());

  writefln("param: %s", param.value());

  writefln("extra (unknown values): %s", parse.remainder());

  writefln("passthrough: %s", parse.passthrough());
