# NAME
File::Rotate::Simple - no-frills file rotation
# VERSION
version v0.3.0
# SYNOPSIS
```perl
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:
```perl
File::Rotate::Simple->rotate(
file => '/foo/bar/backup.tar.gz',
age => 7,
max => 30,
);
```
or the object-oriented interface:
```perl
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"](#max) is specified, then any files with a larger numeric suffix
are deleted.
If ["age"](#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"](#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](https://metacpan.org/pod/Path%3A%3ATiny) object.
## `files`
When ["rotate"](#rotate) is called as a constructor, you can specify an array
reference of files to rotate:
```perl
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](https://metacpan.org/pod/Time%3A%3APiece#strftime) 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"](#extension_format) rather than appending it. Use this when you want
to preserve the existing extension in a rotated backup, e.g.
```perl
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"](#file) is missing. True by
default, for backwards compatability.
Added in v0.2.0.
## `touch`
Touch ["file"](#file) after rotating.
## `time`
A time object corresponding to the time used for generating
timestamped extensions in ["extension\_format"](#extension_format). It defaults to a
[Time::Piece](https://metacpan.org/pod/Time%3A%3APiece) object with the current local time.
You can specify an alternative time (including time zone) in the
constructor, e.g.
```perl
use Time::Piece;
my $r = File::Rotate::Simple->new(
file => 'myapp.log',
time => gmtime(),
extension_format => '.%Y%m%d',
);
```
[Time::Moment](https://metacpan.org/pod/Time%3A%3AMoment) and [DateTime](https://metacpan.org/pod/DateTime) objects can also be given.
Unlike other attributes, ["time"](#time) is read-write, so that it can be
updated between calls to ["rotate"](#rotate):
```perl
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.
```perl
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](https://metacpan.org/pod/File%3A%3ARotate%3A%3ABackup)
- [File::Write::Rotate](https://metacpan.org/pod/File%3A%3AWrite%3A%3ARotate)
There are also several logging modueles that support log rotation.
