NAME

Zoidberg::Utils::Output - Zoidberg output routines

SYNOPSIS

         use Zoidberg::Utils qw/:output/;
 
 

         # use this instead of perlfunc print
         output "get some string outputted";
         output { string => 'or some data struct dumped' };
 
 

DESCRIPTION

This module provides some routines used by various Zoidberg modules to output data.

Although when working within the Zoidberg framework this module should be used through the Zoidberg::Utils interface, it also can be used on it's own.

EXPORT

By default all of the below except "typed_output".

METHODS

"output(@_)"

Output a list of possibly mixed data structs as nice as possible.

A reference to an array of plain scalars may be outputted as a multicolumn list, more complex data will be dumped using Data::Dumper.

"message(@_)"

Like "output()" but tags data as a message, in non-interactive mode these may not be printed at all.

"debug(@_)"

Like "output()" tags the data as debug output, will only be printed when in debug mode. Debug ouput will be printed to STDERR if printed at all.

"complain(@_)"

Like "output" but intended for error messages, data will be printed to STDERR. Has some glue for error objects created by Zoidberg::Utils::Error. Prints $@ when no argument is given.

"typed_output($type, @_)"

Method that can be used to define output types that don't fit in the above group. $type must be a plain string that is used as output 'tag'.

"output_is_captured($type, @_)"

Method that returns a boolean that tells whether output is captured or not. This can be used to make terminal output different from data struct output.
