VERSION

       This document describes Data::Show version 0.002003

SYNOPSIS

           use Data::Show;

           show %foo;
           show @bar;
           show (
               @bar,
               $baz,
           );
           show $baz;
           show $ref;
           show @bar[do{1..2;}];
           show 2*3;
           show 'a+b';
           show 100 * sqrt length $baz;
           show $foo{q[;{{{]};

DESCRIPTION

       This module provides a simple wrapper around the Data::Dump module.

       A call to "show" data-dumps its arguments, prefaced by a divider line that reports the
       arguments and the file and line from which "show()" was called.

       For example, the code in the SYNOPSIS would produce something like:

           ======(  %foo  )========================[ 'demo.pl', line 11 ]======

               { foo => 1, food => 'b', foon => [3, 4, 5, 6, 7, 8, 9, 10] }

           ======(  @bar  )========================[ 'demo.pl', line 12 ]======

               ["b", "a", "r"]

           ======(  @bar, $baz,  )=================[ 'demo.pl', line 13 ]======

               ("b", "a", "r", "baz")

           ======(  $baz  )========================[ 'demo.pl', line 17 ]======

               "baz"

           ======(  $ref  )========================[ 'demo.pl', line 18 ]======

               ["b", "a", "r"]

           ======(  @bar[do{1..2;}]  )=============[ 'demo.pl', line 19 ]======

               ("a", "r")

           ======(  2*3  )=========================[ 'demo.pl', line 20 ]======

               6

           ======(  'a+b'  )=======================[ 'demo.pl', line 21 ]======

               "a+b"

           ======(  100 * sqrt length $baz  )======[ 'demo.pl', line 22 ]======

               "173.205080756888"

           ======(  $foo{q[;{{{]}  )===============[ 'demo.pl', line 23 ]======

               undef

           ======(  'foo' ~~ m/;{\/{/  )===========[ 'demo.pl', line 25 ]======

               ""

INTERFACE

       "show()"
           This is the only subroutine provided by the module.  It is always exported.

           "show()" can be called with any number of arguments and data-dumps them all with a
           suitable header indicating the arguments' names, and the file and line from which
           "show()" was called.

           "show()" does not return a useful value.

DIAGNOSTICS

       None, apart from those provided by Data::Dump;

CONFIGURATION AND ENVIRONMENT

       Data::Show requires no configuration files or environment variables.

DEPENDENCIES

       Only works under Perl 5.10 and later.

       Requires the Data::Dump module.

INCOMPATIBILITIES

       None reported.

BUGS AND LIMITATIONS

       Uses sophisticated regexes to parse out the argument list from the source. Hence subject
       to the usual limitations of this technique (namely, that it may get the argument list
       wrong occasionally).

       No bugs have been reported.

       Please report any bugs or feature requests to "bug-data-show@rt.cpan.org", or through the
       web interface at <http://rt.cpan.org>.
