472 | A new dumper is created by a call | |
473 | ||
474 | $d = new Dumpvalue(option1 => value1, option2 => value2) | |
475 | ||
476 | Recognized options: | |
477 | ||
478 | =over | |
479 | ||
480 | =item C<arrayDepth>, C<hashDepth> | |
481 | ||
482 | Print only first N elements of arrays and hashes. If false, prints all the | |
483 | elements. | |
484 | ||
485 | =item C<compactDump>, C<veryCompact> | |
486 | ||
487 | Change style of array and hash dump. If true, short array | |
488 | may be printed on one line. | |
489 | ||
490 | =item C<globPrint> | |
491 | ||
492 | Whether to print contents of globs. | |
493 | ||
494 | =item C<DumpDBFiles> | |
495 | ||
496 | Dump arrays holding contents of debugged files. | |
497 | ||
498 | =item C<DumpPackages> | |
499 | ||
500 | Dump symbol tables of packages. | |
501 | ||
502 | =item C<DumpReused> | |
503 | ||
504 | Dump contents of "reused" addresses. | |
505 | ||
506 | =item C<tick>, C<HighBit>, C<printUndef> | |
507 | ||
508 | Change style of string dump. Default value of C<tick> is C<auto>, one | |
509 | can enable either double-quotish dump, or single-quotish by setting it | |
510 | to C<"> or C<'>. By default, characters with high bit set are printed | |
511 | I<as is>. | |
512 | ||
513 | =item C<UsageOnly> | |
514 | ||
515 | I<very> rudimentally per-package memory usage dump. If set, | |
516 | C<dumpvars> calculates total size of strings in variables in the package. | |
517 | ||
518 | =item unctrl | |
519 | ||
520 | Changes the style of printout of strings. Possible values are | |
521 | C<unctrl> and C<quote>. | |
522 | ||
523 | =item subdump | |
524 | ||
525 | Whether to try to find the subroutine name given the reference. | |
526 | ||
527 | =item bareStringify | |
528 | ||
529 | Whether to write the non-overloaded form of the stringify-overloaded objects. | |
530 | ||
531 | =item quoteHighBit | |
532 | ||
533 | Whether to print chars with high bit set in binary or "as is". | |
534 | ||
535 | =item stopDbSignal | |
536 | ||
537 | Whether to abort printing if debugger signal flag is raised. | |
538 | ||
539 | =back | |
540 | ||
541 | Later in the life of the object the methods may be queries with get() | |
542 | method and set() method (which accept multiple arguments). | |
543 | ||
544 | =head2 Methods | |
545 | ||
546 | =over | |
547 | ||
548 | =item dumpValue | |
549 | ||
550 | $dumper->dumpValue($value); | |
551 | $dumper->dumpValue([$value1, $value2]); | |
552 | ||
553 | =item dumpValues | |
554 | ||
555 | $dumper->dumpValues($value1, $value2); | |
556 | ||
557 | =item dumpvars | |
558 | ||
559 | $dumper->dumpvars('my_package'); | |
560 | $dumper->dumpvars('my_package', 'foo', '~bar$', '!......'); | |
561 | ||
562 | The optional arguments are considered as literal strings unless they | |
563 | start with C<~> or C<!>, in which case they are interpreted as regular | |
564 | expressions (possibly negated). | |
565 | ||
566 | The second example prints entries with names C<foo>, and also entries | |
567 | with names which ends on C<bar>, or are shorter than 5 chars. | |
568 | ||
569 | =item set_quote | |
570 | ||
571 | $d->set_quote('"'); | |
572 | ||
573 | Sets C<tick> and C<unctrl> options to suitable values for printout with the | |
574 | given quote char. Possible values are C<auto>, C<'> and C<">. | |
575 | ||
576 | =item set_unctrl | |
577 | ||
578 | $d->set_unctrl('"'); | |
579 | ||
580 | Sets C<unctrl> option with checking for an invalid argument. | |
581 | Possible values are C<unctrl> and C<quote>. | |
582 | ||
583 | =item compactDump | |
584 | ||
585 | $d->compactDump(1); | |
586 | ||
587 | Sets C<compactDump> option. If the value is 1, sets to a reasonable | |
588 | big number. | |
589 | ||
590 | =item veryCompact | |
591 | ||
592 | $d->veryCompact(1); | |
593 | ||
594 | Sets C<compactDump> and C<veryCompact> options simultaneously. | |
595 | ||
596 | =item set | |
597 | ||
598 | $d->set(option1 => value1, option2 => value2); | |
599 | ||
600 | =item get | |
601 | ||
602 | @values = $d->get('option1', 'option2'); | |
