3. Information about the perl-Data-Dump package on openSUSE Leap

Information for package perl-Data-Dump:
---------------------------------------
Repository : Main Repository
Name : perl-Data-Dump
Version : 1.23-1.24
Arch : noarch
Vendor : SUSE LLC
Installed Size : 49.7 KiB
Installed : No
Status : not installed
Source package : perl-Data-Dump-1.23-1.24.src
Upstream URL : http://search.cpan.org/dist/Data-Dump/
Summary : Pretty printing of data structures
Description :
This module provide a few functions that traverse their argument and
produces a string as its result. The string contains Perl code that, when
'eval'ed, produces a deep copy of the original arguments.
The main feature of the module is that it strives to produce output that is
easy to read. Example:
@a = (1, [2, 3], {4 => 5});
dump(@a);
Produces:
"(1, [2, 3], { 4 => 5 })"
If you dump just a little data, it is output on a single line. If you dump
data that is more complex or there is a lot of it, line breaks are
automatically added to keep it easy to read.
The following functions are provided (only the dd* functions are exported
by default):
* dump( ... )
* pp( ... )
Returns a string containing a Perl expression. If you pass this string to
Perl's built-in eval() function it should return a copy of the arguments
you passed to dump().
If you call the function with multiple arguments then the output will be
wrapped in parenthesis "( ..., ... )". If you call the function with a
single argument the output will not have the wrapping. If you call the
function with a single scalar (non-reference) argument it will just
return the scalar quoted if needed, but never break it into multiple
lines. If you pass multiple arguments or references to arrays of hashes
then the return value might contain line breaks to format it for easier
reading. The returned string will never be "\n" terminated, even if
contains multiple lines. This allows code like this to place the
semicolon in the expected place:
print '$obj = ', dump($obj), ";\n";
If dump() is called in void context, then the dump is printed on STDERR
and then "\n" terminated. You might find this useful for quick debug
printouts, but the dd*() functions might be better alternatives for this.
There is no difference between dump() and pp(), except that dump() shares
its name with a not-so-useful perl builtin. Because of this some might
want to avoid using that name.
* quote( $string )
Returns a quoted version of the provided string.
It differs from 'dump($string)' in that it will quote even numbers and
not try to come up with clever expressions that might shorten the output.
If a non-scalar argument is provided then it's just stringified instead
of traversed.
* dd( ... )
* ddx( ... )
These functions will call dump() on their argument and print the result
to STDOUT (actually, it's the currently selected output handle, but
STDOUT is the default for that).
The difference between them is only that ddx() will prefix the lines it
prints with "# " and mark the first line with the file and line number
where it was called. This is meant to be useful for debug printouts of
state within programs.
* dumpf( ..., \&filter )
Short hand for calling the dump_filtered() function of the
Data::Dump::Filtered manpage. This works like dump(), but the last
argument should be a filter callback function. As objects are visited the
filter callback is invoked and it can modify how the objects are dumped.
