NAME

Debug::Easy - A Handy Debugging Module

SYNOPSIS

use Debug::Easy;

my $debug = Debug::Easy->new( 'LogLevel' => 'DEBUG', 'Color' => 1 );

my $debug_level = 'NOTICE';

# $debug_level is the maximum level to report, and ignore the rest.
# It must be the first parameter passed to the object, when outputing
# a specific message.  This identifies to the module what type of
# message it is.
#
# The following is a list, in order of level, of the parameter to
# pass to the debug method:
#
#  ERR      = Error
#  WARN     = Warning
#  NOTICE   = Notice
#  INFO     = Information
#  VERBOSE  = Special version of INFO that does not output any
#             Logging headings and goes to STDOUT instead of STDERR.
#             Very useful for verbose modes in your scripts.
#  DEBUG    = Level 1 Debugging messages
#  DEBUGMAX = Level 2 Debugging messages

$debug->debug(__LINE__,$debug_level,"Message");

$debug->debug(__LINE__,'ERR',      ['Error message']);
$debug->debug(__LINE__,'WARN',     ['Warning message']);
$debug->debug(__LINE__,'NOTICE',   ['Notice message']);
$debug->debug(__LINE__,'INFO',     ['Information and VERBOSE mode message']);
$debug->debug(__LINE__,'DEBUG',    ['Level 1 Debug message']);
$debug->debug(__LINE__,'DEBUGMAX', ['Level 2 Debug message']);

my @messages = ('First Message','Second Message',"Third\nMessage");

$debug->debug(__LINE__,$debug_level,\@messages);

DESCRIPTION

This module makes it easy to add debugging features to your code, Without having to re-invent the wheel. It uses STDERR and ANSI color Formatted text output, as well as indented and multiline text formatting, to make things easy to read.

Benchmarking is automatic, to make it easy to spot bottlenecks in code. It automatically stamps from where it was called, and makes debug coding so much easier, without having to include the location of the debugging location in your debug message. This is all taken care of for you.

It also allows multiple output levels from errors only, to warnings, to notices, to verbose information, to full on debug output. All of this fully controllable by the coder.

It is essentially a smart wrapper on top of Log::Fast.

EXPORTED VARIABLES

@Levels

A simple list of all the acceptable debug levels to pass to the {debug} method,
and the {new} method.

METHODS

new

The parameter names are case insensitive as of Version 0.04.

LogLevel [level]

This adjusts the global log level of the Debug object. It requires a string.

ERR (default)

This level shows only error messages and all other messages are not shown.

WARN

This level shows error and warning messages. All other messages are not shown.

NOTICE

This level shows error, warning, and notice messages. All other messages are not shown.

INFO

This level shows error, warning, notice, and information messages. Only debug level messages are not shown.

VERBOSE

This level can be used as a way to do "Verbose" output for your scripts. It ouputs INFO level messages without logging headers and on STDOUT instead of STDERR.

DEBUG

This level shows error, warning, notice, information, and level 1 debugging messages. Level 2 Debug messages are not shown.

DEBUGMAX

This level shows all messages, including level 2 debugging messages.

Color [boolean] (Not case sensitive)
0, Off, or False (Off)
This turns off colored output.  Everything is plain text only.
1, On, or True (On - Default)
This turns on colored output.  This makes it easier to spot all of
the different types of messages throughout a sea of debug output.
You can pipe the output to Less, and see color, by using it's
switch "-r".
TimeStamp [pattern]

Make this an empty string to turn it off, otherwise:

%T
Formats the timestamp as HH:MM:SS.  This is the default for the
timestamp.
%S
Formats the timestamp as seconds.milliseconds.  Normally not needed,
as the benchmark is more helpful.
%T %S
Combines both of the above.  Normally this is just too much, but here
if you really want it.
DateStamp [pattern]

Make this an empty string to turn it off, otherwise:

%D
Formats the datestamp as YYYY-MM-DD.  It is the default, and the only
option.
Type
Output type. Possible values are: 'fh' (output to any already open
filehandle) and 'unix' (output to syslog using UNIX socket).
fh
When set to 'fh', you have to also set {FileHandle} to any open filehandle
(like "\*STDERR", which is the default).
unix
When set to 'unix', you have to also set {FileHandle} to a path pointing to an
existing unix socket (typically it's '/dev/log').
FileHandle
File handle to write log messages if {Type} set to 'fh' (which is the default).

Syslog's UNIX socket path to write log messages if {Type} set to 'unix'.

debug

The parameters must be passed in the order given

LINE
The line number with which the debug was called.  Typically '__LINE__'
LEVEL
The log level with which this message is to be triggered
MESSAGE(S)
A string or list of strings to output line by line.
