Mail::Ezmlm::Archive - Object Methods for Ezmlm-Idx Archives

SYNOPSIS

 use Mail::Ezmlm::Archive;
 $archive = Mail::Ezmlm::Archive->new('/path/to/list/folder');
 
 $message_count = $archive->getcount;
 @available_months = $archive->getmonths;
 $threads = $archive->getthreads('200304');

ABSTRACT

Mail::Ezmlm::Archive is designed to provide an object interface to the message archives maintained by the ezmlm-idx software. See the ezmlm web page for a complete description of that software: <http://www.ezmlm.org>.

This version is designed to work with ezmlm 0.53 and ezmlm-idx 0.40.

DESCRIPTION

Setting up a new Archive object

        use Mail::Ezmlm::Archive;
        $archive = Mail::Ezmlm::Archive->new('/path/to/list/folder');

Changing which list the Archive object points at

        $archive->setlist('/full/path/to/other/list');

Getting count of archived messages

        $message_count = $archive->getcount;

Actually the getcount methods reads message count from DIR/num file, so we'd better consider the result as count of distributed messages instead of archived.

Getting a list of months

        @available_months = $archive->getmonths;

This returns an array of strings in the 'YYYYMM' format, such as '200304', which represent months for which we have archived messages.

Getting a list of threads in a given month

        $threads = $archive->getthreads('200304');

This method returns a reference to an array, whose elements are hashes with these keys:

subject

The subject of the thread, as archived in DIR/archived/threads/$month

count

Count of messages in the thread

offset

Id of first message in the thread

id

Thread Id.

date

The date of last message in the thread, as archived in DIR/archived/threads/$month

Getting list of messages in a given thread

        $messages = $archive->getthread('nknmgklhcgijmbonmbkk');

This method returns a reference to a hash, which has two keys: 'subject' and 'messages'. The former contains the subject of the first message in the thread. The latter is a reference to an array, whose elements are hashes with these keys:

id

Message Id for retrieving.

month

Month of the message, in 'YYYYMM' format

authorid

Author Id

author

Full value of the 'From:' line

Retrieving a message

        $message = $archive->getmessage('52');

This method returns a reference to a hash with two keys: text and month. The first contains the full raw message, and the message contains the month in YYYYMM format. It returns undef if the message doesn't exist.

CACHING

All opened files are cached by default, so that we do not need to overload the filesystem for doing normal listing and browsing operations. However, caching can be disabled to reduce memory usage:

        $archive->nocache;

Then, to enable it again:

        $archive->cache;

BUGS AND LIMITATIONS

• No methods for author-based browsing.
• Not enough object oriented, maybe? :-)
