=head1 NAME
String::Flogger - string munging for loggers
=head1 VERSION
version 1.101241
=head1 SYNOPSIS
use String::Flogger qw(flog);
my @inputs = (
'simple!',
[ 'slightly %s complex', 'more' ],
[ 'and inline some data: %s', { look => 'data!' } ],
[ 'and we can defer evaluation of %s if we want', sub { 'stuff' } ],
sub { 'while avoiding sprintfiness, if needed' },
);
say flog($_) for @inputs;
The above will output:
simple!
slightly more complex
and inline some data: {{{ "look": "data!" }}}
and we can defer evaluation of stuff if we want
while avoiding sprintfiness, if needed
=head1 METHODS
=head2 flag
This method is described in the synopsis.
=head2 format_string
$flogger->format_string($fmt, \@input);
This method is used to take the formatted arguments for a format string (when
C<flog> is passed an arrayref) and turn it into a string. By default, it just
uses C<L<perlfunc/sprintf>>.
