NAME

Log::Dispatch::ArrayWithLimits - Log to array, with some limits applied

VERSION

This document describes version 0.050 of Log::Dispatch::ArrayWithLimits (from Perl distribution Log-Dispatch-ArrayWithLimits), released on 2019-01-09.

SYNOPSIS

 use Log::Dispatch::ArrayWithLimits;

 my $file = Log::Dispatch::ArrayWithLimits(
     min_level     => 'info',
     array         => $ary,    # default: [], you can always refer by name e.g. 'My::array' to refer to @My::array
     max_elems     => 100,     # defaults unlimited
 );

 $file->log(level => 'info', message => "Your comment\n");

DESCRIPTION

This module functions similarly to Log::Dispatch::Array, with a few differences:

only the messages (strings) are stored
allow specifying array variable name (e.g. "My::array" instead of \@My:array)
This makes it possible to use in Log::Log4perl configuration, which is a text file.
can apply some limits
Currently only max_elems (the maximum number of elements in the array) is available. Future limits will be added.

Logging to an in-process array can be useful when debugging/testing, or when you want to let users of your program connect to your program to request viewing the ogs being produced.

METHODS

new(%args)

Constructor. This method takes a hash of parameters. The following options are valid: "min_level" and "max_level" (see Log::Dispatch documentation); "array" (a reference to an array, or if value is string, will be taken as name of array variable; this is so this module can be used/configured e.g. by Log::Log4perl because configuration is specified via a text file), "max_elems".

log_message(message => STR)

Send a message to the appropriate output. Generally this shouldn't be called directly but should be called through the "log()" method (in LLog::Dispatch::Output>).
