PPIx::Regexp::Dumper(3User Contributed Perl DocumentatiPPIx::Regexp::Dumper(3) 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 THIS ARGUMENT IS DEPRECATED. See DEPRECATION NOTICE in PPIx::QuoteLike for the details. If true, postfix dereferences are recognized in code and interpolations. See the tokenizer's new() for details. ppi Boolean If true, any Perl code contained in the object will be dumped. short Boolean If true, leading 'PPIx::Regexp::' will be removed from the class names in the output. 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.
