487 | =head1 DESCRIPTION |
488 | |
489 | =head2 Creation |
490 | |
491 | A new dumper is created by a call |
492 | |
493 | $d = new Dumpvalue(option1 => value1, option2 => value2) |
494 | |
495 | Recognized options: |
496 | |
497 | =over |
498 | |
499 | =item C<arrayDepth>, C<hashDepth> |
500 | |
501 | Print only first N elements of arrays and hashes. If false, prints all the |
502 | elements. |
503 | |
504 | =item C<compactDump>, C<veryCompact> |
505 | |
506 | Change style of array and hash dump. If true, short array |
507 | may be printed on one line. |
508 | |
509 | =item C<globPrint> |
510 | |
511 | Whether to print contents of globs. |
512 | |
513 | =item C<DumpDBFiles> |
514 | |
515 | Dump arrays holding contents of debugged files. |
516 | |
517 | =item C<DumpPackages> |
518 | |
519 | Dump symbol tables of packages. |
520 | |
521 | =item C<DumpReused> |
522 | |
523 | Dump contents of "reused" addresses. |
524 | |
525 | =item C<tick>, C<HighBit>, C<printUndef> |
526 | |
527 | Change style of string dump. Default value of C<tick> is C<auto>, one |
528 | can enable either double-quotish dump, or single-quotish by setting it |
529 | to C<"> or C<'>. By default, characters with high bit set are printed |
530 | I<as is>. |
531 | |
532 | =item C<UsageOnly> |
533 | |
534 | I<very> rudimentally per-package memory usage dump. If set, |
535 | C<dumpvars> calculates total size of strings in variables in the package. |
536 | |
537 | =item unctrl |
538 | |
539 | Changes the style of printout of strings. Possible values are |
540 | C<unctrl> and C<quote>. |
541 | |
542 | =item subdump |
543 | |
544 | Whether to try to find the subroutine name given the reference. |
545 | |
546 | =item bareStringify |
547 | |
548 | Whether to write the non-overloaded form of the stringify-overloaded objects. |
549 | |
550 | =item quoteHighBit |
551 | |
552 | Whether to print chars with high bit set in binary or "as is". |
553 | |
554 | =item stopDbSignal |
555 | |
556 | Whether to abort printing if debugger signal flag is raised. |
557 | |
558 | =back |
559 | |
560 | Later in the life of the object the methods may be queries with get() |
561 | method and set() method (which accept multiple arguments). |
562 | |
563 | =head2 Methods |
564 | |
565 | =over |
566 | |
567 | =item dumpValue |
568 | |
569 | $dumper->dumpValue($value); |
570 | $dumper->dumpValue([$value1, $value2]); |
571 | |
572 | =item dumpValues |
573 | |
574 | $dumper->dumpValues($value1, $value2); |
575 | |
576 | =item dumpvars |
577 | |
578 | $dumper->dumpvars('my_package'); |
579 | $dumper->dumpvars('my_package', 'foo', '~bar$', '!......'); |
580 | |
581 | The optional arguments are considered as literal strings unless they |
582 | start with C<~> or C<!>, in which case they are interpreted as regular |
583 | expressions (possibly negated). |
584 | |
585 | The second example prints entries with names C<foo>, and also entries |
586 | with names which ends on C<bar>, or are shorter than 5 chars. |
587 | |

589 | |
590 | $d->set_quote('"'); |
591 | |
592 | Sets C<tick> and C<unctrl> options to suitable values for printout with the |
593 | given quote char. Possible values are C<auto>, C<'> and C<">. |
594 | |
595 | =item set_unctrl |
596 | |
597 | $d->set_unctrl('"'); |
598 | |
599 | Sets C<unctrl> option with checking for an invalid argument. |
600 | Possible values are C<unctrl> and C<quote>. |
601 | |
602 | =item compactDump |
603 | |
604 | $d->compactDump(1); |
605 | |
