|
||||
* of POSIX {@code getopt()} and GNU {@code getopt_long()}.</p>
|
||||
*
|
||||
* <p>This parser supports short options and long options.</p>
|
||||
*
|
||||
* <ul>
|
||||
* <li><dfn>Short options</dfn> begin with a single hyphen ("<kbd>-</kbd>") followed
|
||||
* by a single letter or digit, or question mark ("<kbd>?</kbd>"), or dot
|
||||
* ("<kbd>.</kbd>").</li>
|
||||
*
|
||||
* <li>Short options can accept single arguments. The argument can be made required or
|
||||
* optional. The option's argument can occur:
|
||||
* <ul>
|
||||
* <li>in the slot after the option, as in <kbd>-d /tmp</kbd></li>
|
||||
* <li>right up against the option, as in <kbd>-d/tmp</kbd></li>
|
||||
* <li>right up against the option separated by an equals sign (<kbd>"="</kbd>),
|
||||
* as in <kbd>-d=/tmp</kbd></li>
|
||||
* </ul>
|
||||
* To specify <var>n</var> arguments for an option, specify the option <var>n</var>
|
||||
* times, once for each argument, as in <kbd>-d /tmp -d /var -d /opt</kbd>; or, when
|
||||
* using the {@linkplain ArgumentAcceptingOptionSpec#withValuesSeparatedBy(char)
|
||||
* "separated values"} clause of the "fluent interface" (see below), give multiple
|
||||
* values separated by a given character as a single argument to the option.</li>
|
||||
*
|
||||
* <li>Short options can be clustered, so that <kbd>-abc</kbd> is treated as
|
||||
* <kbd>-a -b -c</kbd>, if none of those options can accept arguments.</li>
|
||||
*
|
||||
* <li>An argument consisting only of two hyphens (<kbd>"--"</kbd>) signals that the
|
||||
* remaining arguments are to be treated as non-options.</li>
|
||||
*
|
||||
* <li>An argument consisting only of a single hyphen is considered a non-option
|
||||
* argument (though it can be an argument of an option). Many Unix programs treat
|
||||
* single hyphens as stand-ins for the standard input or standard output streams.</li>
|
||||
*
|
||||
* <li><dfn>Long options</dfn> begin with two hyphens (<kbd>"--"</kbd>), followed
|
||||
* by multiple letters, digits, hyphens, question marks, or dots. A hyphen cannot be
|
||||
* the first character of a long option specification when configuring the parser.</li>
|
||||
*
|
||||
* <li>You can abbreviate long options, so long as the abbreviation is unique.</li>
|
||||
*
|
||||
* <li>Long options can accept single arguments. The argument can be made required or
|
||||
* optional. The option's argument can occur:
|
||||
* <ul>
|
||||
* <li>in the slot after the option, as in <kbd>--directory /tmp</kbd></li>
|
||||
* <li>right up against the option separated by an equals sign (<kbd>"="</kbd>),
|
||||
* as in <kbd>--directory=/tmp</kbd>
|
||||
* </ul>
|
||||
* Specify multiple arguments for a long option in the same manner as for short options
|
||||
* (see above).</li>
|
||||
*
|
||||
* <li>You can use a single hyphen (<kbd>"-"</kbd>) instead of a double hyphen
|
||||
* (<kbd>"--"</kbd>) for a long option.</li>
|
||||
*
|
||||
* <li>The option <kbd>-W</kbd> is reserved. If you tell the parser to {@linkplain
|
||||
* #recognizeAlternativeLongOptions(boolean) recognize alternative long options}, then
|
||||
* it will treat, for example, <kbd>-W foo=bar</kbd> as the long option
|
||||
* <kbd>foo</kbd> with argument <kbd>bar</kbd>, as though you had written
|
||||
* <kbd>--foo=bar</kbd>.</li>
|
||||
*
|
||||
* <li>You can specify <kbd>-W</kbd> as a valid short option, or use it as an
|
||||
* abbreviation for a long option, but {@linkplain
|
||||
* #recognizeAlternativeLongOptions(boolean) recognizing alternative long options} will
|
||||
* always supersede this behavior.</li>
|
||||
*
|
||||
* <li>You can specify a given short or long option multiple times on a single command
|
||||
* line. The parser collects any arguments specified for those options as a list.</li>
|
||||
*
|
||||
* <li>If the parser detects an option whose argument is optional, and the next argument
|
||||
* "looks like" an option, that argument is not treated as the argument to the option,
|
||||
* but as a potentially valid option. If, on the other hand, the optional argument is
|
||||
* typed as a derivative of {@link Number}, then that argument is treated as the
|
||||
* negative number argument of the option, even if the parser recognizes the
|
||||
* corresponding numeric option. For example:
|
||||
* <pre><code>
|
||||
* OptionParser parser = new OptionParser();
|
||||
* parser.accepts( "a" ).withOptionalArg().ofType( Integer.class );
|
||||
* parser.accepts( "2" );
|
||||
* OptionSet options = parser.parse( "-a", "-2" );
|
||||
* </code></pre>
|
||||
* In this case, the option set contains <kbd>"a"</kbd> with argument <kbd>-2</kbd>,
|
||||
* not both <kbd>"a"</kbd> and <kbd>"2"</kbd>. Swapping the elements in the
|
||||
* <var>args</var> array gives the latter.</li>
|
||||
* </ul>
|
||||
*
|
||||
* <p>There are two ways to tell the parser what options to recognize:</p>
|
||||
*
|
||||
* <ol>
|
||||
* <li>A "fluent interface"-style API for specifying options, available since
|
||||
* version 2. Sentences in this fluent interface language begin with a call to
|
||||
* {@link #accepts(String) accepts} or {@link #acceptsAll(Collection) acceptsAll}
|
||||
* methods; calls on the ensuing chain of objects describe whether the options can take
|
||||
* an argument, whether the argument is required or optional, to what type arguments of
|
||||
* the options should be converted if any, etc. Since version 3, these calls return
|
||||
* an instance of {@link OptionSpec}, which can subsequently be used to retrieve the
|
||||
* arguments of the associated option in a type-safe manner.</li>
|
||||
*
|
||||
* <li>Since version 1, a more concise way of specifying short options has been to use
|
||||
* the special {@linkplain #OptionParser(String) constructor}. Arguments of options
|
||||
* specified in this manner will be of type {@link String}. Here are the rules for the
|
||||
* format of the specification strings this constructor accepts:
|
||||
*
|
||||
* <ul>
|
||||
* <li>Any letter or digit is treated as an option character.</li>
|
||||
*
|
||||
* <li>If an option character is followed by a single colon (<kbd>":"</kbd>),
|
||||
* then the option requires an argument.</li>
|
||||
*
|
||||
* <li>If an option character is followed by two colons (<kbd>"::"</kbd>), then
|
||||
* the option accepts an optional argument.</li>
|
||||
*
|
||||
* <li>Otherwise, the option character accepts no argument.</li>
|
||||
*
|
||||
* <li>If the option specification string begins with a plus sign (<kbd>"+"</kbd>),
|
||||
* the parser will behave "POSIX-ly correct".</li>
|
||||
*
|
||||
* <li>If the option specification string contains the sequence <kbd>"W;"</kbd>
|
||||
* (capital W followed by a semicolon), the parser will recognize the alternative
|
||||
* form of long options.</li>
|
||||
* </ul>
|
||||
* </li>
|
||||
* </ol>
|
||||
*
|
||||
* <p>Each of the options in a list of options given to {@link #acceptsAll(Collection)
|
||||
* acceptsAll} is treated as a synonym of the others. For example:
|
||||
* <pre>
|
||||
* <code>
|
||||
* OptionParser parser = new OptionParser();
|
||||
* parser.acceptsAll( asList( "w", "interactive", "confirmation" ) );
|
||||
* OptionSet options = parser.parse( "-w" );
|
||||
* </code>
|
||||
* </pre>
|
||||
* In this case, <code>options.{@link OptionSet#has(String) has}</code> would answer
|
||||
* {@code true} when given arguments <kbd>"w"</kbd>, <kbd>"interactive"</kbd>, and
|
||||
* <kbd>"confirmation"</kbd>. The {@link OptionSet} would give the same responses to
|
||||
* these arguments for its other methods as well.</p>
|
||||
*
|
||||
* <p>By default, as with GNU {@code getopt()}, the parser allows intermixing of options
|
||||
* and non-options. If, however, the parser has been created to be "POSIX-ly correct",
|
||||
* then the first argument that does not look lexically like an option, and is not a
|
||||
* required argument of a preceding option, signals the end of options. You can still
|
||||
* bind optional arguments to their options using the abutting (for short options) or
|
||||
* <kbd>=</kbd> syntax.</p>
|
||||
*
|
||||
* <p>Unlike GNU {@code getopt()}, this parser does not honor the environment variable
|
||||
* {@code POSIXLY_CORRECT}. "POSIX-ly correct" parsers are configured by either:</p>
|
||||
*
|
||||
* <ol>
|
||||
* <li>using the method {@link #posixlyCorrect(boolean)}, or</li>
|
||||
*
|
||||
* <li>using the {@linkplain #OptionParser(String) constructor} with an argument whose
|
||||
* first character is a plus sign (<kbd>"+"</kbd>)</li>
|
||||
* </ol>
