NAME

File::Rotate::Simple - no-frills file rotation

VERSION

version v0.3.0

SYNOPSIS

  use File::Rotate::Simple qw/ rotate_files /;

  rotate_files(
      file => '/foo/bar/backup.tar.gz',
      age  => 7,
      max  => 30,
  );

  rotate_files(
      files => [ qw{ /var/log/foo.log /var/log/bar.log } ],
      max   => 7,
  );

or the legacy interface:

  File::Rotate::Simple->rotate(
      file => '/foo/bar/backup.tar.gz',
      age  => 7,
      max  => 30,
  );

or the object-oriented interface:

  my $r = File::Rotate::Simple->new(
      file => '/foo/bar/backup.tar.gz',
      age  => 7,
      max  => 30,
  );

  $r->rotate;

DESCRIPTION

This module implements simple file rotation.

Files are renamed to have a numeric suffix, e.g. backup.tar.gz is renamed to backup.tar.gz.1. Existing file numbers are incremented.

If "max" is specified, then any files with a larger numeric suffix are deleted.

If "age" is specified, then any files older than that number of days are deleted.

Note that files with the extension 0 are ignored.

ATTRIBUTES

age

The maximum age of files (in days), relative to the "time" attribute. Older files will be deleted.

A value 0 (default) means there is no maximum age.

max

The maximum number of files to keep. Numbered files larger than this will be deleted.

A value of 0 (default) means that there is no maximum number.

Note that it does not track whether intermediate files are missing.

file

The file to rotate. This can be a string or Path::Tiny object.

files

When "rotate" is called as a constructor, you can specify an array reference of files to rotate:

  File::Rotate::Simple->rotate(
     files => \@files,
     ...
  );

start_num

The starting number to use when rotating files. Defaults to 1.

Added in v0.2.0.

extension_format

The extension to add when rotating. This is a string that is passed to "strftime" in Time::Piece with the following addition of the %# code, which corresponds to the rotation number of the file.

Added in v0.2.0.

replace_extension

If defined, it replaces the extension with the one specified by "extension_format" rather than appending it. Use this when you want to preserve the existing extension in a rotated backup, e.g.

    my $r = File::Rotate::Simple->new(
        file              => 'myapp.log',
        extension_format  => '.%#.log',
        replace_extension => '.log',
    );

will rotate the log as myapp.1.log.

Added in v0.2.0.

if_missing

When true, rotate the files even when "file" is missing. True by default, for backwards compatability.

Added in v0.2.0.

touch

Touch "file" after rotating.

time

A time object corresponding to the time used for generating timestamped extensions in "extension_format". It defaults to a Time::Piece object with the current local time.

You can specify an alternative time (including time zone) in the constructor, e.g.

    use Time::Piece;

    my $r = File::Rotate::Simple->new(
        file              => 'myapp.log',
        time              => gmtime(),
        extension_format  => '.%Y%m%d',
    );

Time::Moment and DateTime objects can also be given.

Unlike other attributes, "time" is read-write, so that it can be updated between calls to "rotate":

    use Time::Piece;

    $r->time( localtime );
    $r->rotate;

Added in v0.2.0.

METHODS

rotate

Rotates the files.

This can be called as a constructor.

EXPORTS

None by default. All exports must be made manually.

rotate_files

This is an optionally exported function for rotating files.

  use File::Rotate::Simple qw/ rotate_files /;

  rotate_files(
      file => '/foo/bar/backup.tar.gz',
      age  => 7,
      max  => 30,
  );

Added in v0.2.0.

SUPPORT FOR OLDER PERL VERSIONS

Since v0.3.0, the this module requires Perl v5.14 or later.

Future releases may only support Perl versions released in the last ten years.

If you need this module on Perl v5.8, please use one of the v0.2.x versions of this module. Significant bug or security fixes may be backported to those versions.

SEE ALSO

The following modules have similar functionality:

• File::Rotate::Backup

• File::Write::Rotate

There are also several logging modueles that support log rotation.
