NAME

       PPIx::Regexp::Dumper - Dump the results of parsing regular expressions

SYNOPSIS

        use PPIx::Regexp::Dumper;
        PPIx::Regexp::Dumper->new( 'qr{foo}smx' )
            ->print();

INHERITANCE

       "PPIx::Regexp::Dumper" is a PPIx::Regexp::Support.

       "PPIx::Regexp::Dumper" has no descendants.

DESCRIPTION

       This class generates a formatted dump of a PPIx::Regexp::Element object (or any subclass
       thereof), a PPIx::Regexp::Tokenizer object, or a string that can be made into one of
       these.

METHODS

       This class provides the following public methods. Methods not documented here are private,
       and unsupported in the sense that the author reserves the right to change or remove them
       without notice.

   new
        my $dumper = PPIx::Regexp::Dumper->new(
            '/foo/', ordinal => 1,
        );

       This static method instantiates the dumper. It takes the string, PPI::Element,
       PPIx::Regexp::Element, or PPIx::Regexp::Tokenizer to be dumped as the first argument.
       Optional further arguments may be passed as name/value pairs.

       The following options are recognized:

       default_modifiers array_reference
           This argument is a reference to a list of default modifiers to be applied to the
           statement being parsed. See PPIx::Regexp new() for the details.

       encoding name
           This argument is the name of the encoding of the regular expression. If specified, it
           is passed through to PPIx::Regexp->new(). It also causes an "Encode::encode" to be
           done on any parse content dumped.

       explain boolean
           If true, this option causes the "explain()" output of each object to be dumped.

       indent number
           This argument is the number of additional spaces to indent each level of the parse
           hierarchy. This is ignored if either the "test" or "tokens" argument is true.

           The default is 2.

       margin number
           This is the number of spaces to indent the top level of the parse hierarchy. This is
           ignored if the "test" argument is true.

           The default is zero.

       ordinal boolean
           If true, this option causes the "ordinal" values of PPIx::Regexp::Token::Literal
           objects to be dumped.

       perl_version boolean
           If true, this option causes the "perl_version_introduced" and "perl_version_removed"
           values associated with each object dumped to be displayed.

       postderef boolean
           If true, postfix dereferences are recognized in code and interpolations.  See the
           tokenizer's new() for details.

       strict boolean
           This option is passed on to the parser, where it specifies whether the parse should
           assume "use re 'strict'" is in effect.

           The 'strict' pragma was introduced in Perl 5.22, and its documentation says that it is
           experimental, and that there is no commitment to backward compatibility. The same
           applies to the parse produced when this option is asserted.

           The default is false.

       significant boolean
           If true, this option causes only significant elements to be dumped.

           The default is false.

       test boolean
           If true, this option causes the output to be formatted as a regression test rather
           than as a straight dump. The output produced by asserting this option is explicitly
           undocumented, in the sense that the author reserves the right to change the generated
           output without notice of any kind.

           The default is false.

       tokens boolean
           If true, this option causes a dump of tokenizer output rather than of a full parse of
           the regular expression. This is forced true if the dump is of a
           PPIx::Regexp::Tokenizer.

           The default is false.

       trace number
           If greater than zero, this option causes a trace of the parse. This option is
           unsupported in the sense that the author reserves the right to change it without
           notice.

           The default is zero.

       verbose number
           If greater than zero, this option causes additional information to be given about the
           elements found. This option is unsupported in the sense that the author reserves the
           right to change it without notice.

           The default is zero.

       If the thing to be dumped was a string, unrecognized arguments are passed to
       "PPIx::Regexp::Tokenizer->new()". Otherwise they are ignored.

   list
        print map { "$_\n" } $dumper->list();

       This method produces an array containing the dump output, one line per element. The output
       has no left margin applied, and no newlines.

   print
        $dumper->print();

       This method simply prints the result of "string" to standard out.

   string
        print $dumper->string();

       This method adds left margin and newlines to the output of "list", concatenates the result
       into a single string, and returns that string.
