.TH Data::Dump 3 "2003-12-18" "perl v5.8.0" "User Contributed Perl Documentation"
Data::Dump \- Pretty printing of data structures
\& use Data::Dump qw(dump);
\& @copy_of_list = eval $str;
This module provides a single function called \fIdump()\fR that takes a list
of values as its argument and produces a string as its result. The string
contains Perl code that, when \f(CW\*(C`eval\*(C'\fRed, produces a deep copy of the
original arguments. The string is formatted for easy reading.
If \fIdump()\fR is called in a void context, then the dump is printed on
\&\s-1STDERR\s0 instead of being returned.
If you don't like importing a function that overrides Perl's
not-so-useful builtin, then you can also import the same function as
\&\fIpp()\fR, mnemonic for \*(L"pretty\-print\*(R".
The \f(CW\*(C`Data::Dump\*(C'\fR module grew out of frustration with Sarathy's
in-most-cases-excellent \f(CW\*(C`Data::Dumper\*(C'\fR. Basic ideas and some code are shared
The \f(CW\*(C`Data::Dump\*(C'\fR module provides a much simpler interface than
\&\f(CW\*(C`Data::Dumper\*(C'\fR. No \s-1OO\s0 interface is available and there are no
configuration options to worry about (yet :\-). The other benefit is
that the dump produced does not try to set any variables. It only
returns what is needed to produce a copy of the arguments. This means
that \f(CW\*(C`dump("foo")\*(C'\fR simply returns \f(CW"foo"\fR, and \f(CW\*(C`dump(1..5)\*(C'\fR simply
returns \f(CW\*(C`(1, 2, 3, 4, 5)\*(C'\fR.
The \f(CW\*(C`Data::Dump\*(C'\fR module is written by Gisle Aas <gisle@aas.no>, based
on \f(CW\*(C`Data::Dumper\*(C'\fR by Gurusamy Sarathy <gsar@umich.edu>.
