Log::Fine::Formatter - Log message formatting and sanitization

NAME

Log::Fine::Formatter - Log message formatting and sanitization

SYNOPSIS

Provides a formatting facility for log messages

    use Log::Fine::Handle;
    use Log::Fine::Formatter;

    my $handle    = Log::Fine::Handle::Console->new();
    my $formatter = Log::Fine::Formatter::Detailed->new(
      timestamp_format => "%Y-%m-%d %H:%M:%S"
    );

    # by default, the handle will set its formatter to
    # Log::Fine::Formatter::Basic.  If that's not what you want, set
    # it to preference.
    $handle->formatter($formatter);

    # set the time-stamp to "YYYY-MM-DD HH:MM:SS"
    $formatter->timeStamp("%Y-%m-%d %H:%M:%S");

    # high resolution timestamps with milliseconds are
    # supported thus:
    my $hires_formatter =
      Log::Fine::Formatter::Basic->new(
        hires => 1,
        timestamp_format => "%H:%M:%S.%%millis%%",
      );

DESCRIPTION

Base ancestral class for all formatters. All customized formatters must inherit from this class. The formatter class allows developers to adjust the time-stamp in a log message to a customizable strftime-compatible string without the tedious mucking about writing a formatter sub-class. By default, the time-stamp format is "%c". See timeStamp and the strftime(3) man page on your system for further details.

High Resolution Timestamps

High Resolution time stamps are generated using the the Time::HiRes manpage module. Depending on your distribution of perl, this may or may not be installed. Add the string "%%millis%%" (without the quotes) where you would like milliseconds displayed within your format. For example:

    $formatter->timeStamp("%H:%M:%S.%%millis%%");

Note you must enable high resolution mode during Formatter construction as so:

    my $formatter = Log::Fine::Formatter::Basic->new( hires => 1 );

By default, the time-stamp format for high resolution mode is "%H:%M:%S.%%millis%%". This can be changed via the timeStamp method or set during formatter construction. "%%millis%%" is a case insensitive value, thus "%%MILLIS%%" will work as well as "%%Millis%%".

METHODS

format

Returns the formatted message. Must be sub-classed!

Returns

The formatted string

testFormat

Special method used for unit tests only. Not for use in production environments!

Parameters

Returns

The formatted string

timeStamp

Getter/Setter for a strftime(3)-compatible format string. If passed with an argument, sets the objects strftime compatible string. Otherwise, returns the object's format string.

Parameters

Returns

strftime(3) compatible string
