NAME File::Stamped - time stamped log file SYNOPSIS use File::Stamped; my $fh = File::Stamped->new(pattern => '/var/log/myapp.log.%Y%m%d.txt'); $fh->print("OK\n"); # with Log::Minimal use Log::Minimal; my $fh = File::Stamped->new(pattern => '/var/log/myapp.log.%Y%m%d.txt'); local $Log::Minimal::PRINT = sub { my ( $time, $type, $message, $trace) = @_; print {$fh} "$time [$type] $message at $trace\n"; }; DESCRIPTION File::Stamped is utility library for logging. File::Stamped object mimic file handle. You can use "myapp.log.%Y%m%d.log" style log file. METHODS my $fh = File::Stamped->new(%args); This method creates new instance of File::Stamped. The arguments are followings. You need to specify one of pattern or callback. pattern : Str This is file name pattern. It is the pattern for filename. The format is POSIX::strftime(), see also POSIX. callback : CodeRef You can use a CodeRef to generate file name. File::Stamped pass only one arguments to callback function. Here is a example code: my $pattern = '/path/to/myapp.log.%Y%m%d.log'; my $f = File::Stamped->new(callback => sub { my $file_stamped = shift; local $_ = $pattern; s/!!/$$/ge; $_ = POSIX::strftime($_, localtime()); return $_; }); close_after_write : Bool Default value is 1. iomode: Str This is IO mode for opening file. Default value is '>>:utf8'. autoflush: Bool This attribute changes $|. rotationtime: Int The time between log file generates in seconds. Default value is 1. $fh->print($str: Str) This method prints the $str to the file.
