Mail::Webmail::Gmail(3)

NAME
Mail::Webmail::Gmail - An interface to Google's webmail service

SYNOPSIS
    # Perl script that logs in to Gmail, retrieves the user defined labels
    # Then prints out all new messages under the first label

    use Mail::Webmail::Gmail;

    my $gmail = Mail::Webmail::Gmail->new(
                username => 'username', password => 'password',
            );

    my @labels = $gmail->get_labels();

    my $messages = $gmail->get_messages( label => $labels[0] );

    foreach ( @{ $messages } ) {
        if ( $_->{ 'new' } ) {
            print "Subject: " . $_->{ 'subject' } . " / Blurb: " . $_->{ 'blurb' } . "\n";
        }
    }

ABSTRACT
This perl module uses objects to make it easy to interface with Gmail. I eventually hope to implement all of the functionality of the Gmail website, plus additional features.

DESCRIPTION
Because Gmail is currently in Beta testing, expect this module to break as they make updates to thier interface. I will attempt to keep this module in line with the changes they make, but, if after updating to the newest version of this module, the feature that you require still doesn't work, please contact me with the issue.

  STARTING A NEW GMAIL SESSION
The standard call for starting a new Gmail session is simply

    my $gmail = Mail::Webmail::Gmail->new( username => 'username', password => 'password', );

This module does support the use of a proxy server

    my $gmail = Mail::Webmail::Gmail->new( username => 'username', password => 'password',
                proxy_username => 'proxy_username',
                proxy_password => 'proxy_password',
                proxy_name => 'proxy_server' );

By default, this module only encrypts the logon process. To encrypt the entire session, use the argument encrypt_session

    my $gmail = Mail::Webmail::Gmail->new( username => 'username', password => 'password', encrypt_session => 1 );

After that, you are free to start making requests for data.

  RETRIEVING LABELS
Returns an array of all user defined labels.

    my @labels = $gmail->get_labels();

  EDITING LABELS
There are five actions that can currently be preformed on labels. As a note, this module enforces Gmail's limits on label creation. A label cannot be over 40 characters, and a label cannot contain the character '^'. On failure, error and error_msg are set.

    #creating new labels.
    $gmail->edit_labels( label => 'label_name', action => 'create' );

    #renaming existing labels.
    $gmail->edit_labels( label => 'label_name', action => 'rename', new_name => 'renamed_label' );

    #deleting labels.
    $gmail->edit_labels( label => 'label_name', action => 'delete' );

    #adding a label to a message.
    $gmail->edit_labels( label => 'label_name', action => 'add', msgid => $message_id );

    #removing a label from a message.
    $gmail->edit_labels( label => 'label_name', action => 'remove', msgid => $message_id );

  UPDATING PREFERENCES
The following are the seven preferences and the allowed values that can currently be changed through Mail::Webmail::Gmail

    keyboard_shortcuts = ( 0, 1 )
    indicators         = ( 0, 1 )
    snippets           = ( 0, 1 )
    max_page_size      = ( 25, 50, 100 )
    display_name       = ( '', string value up to 96 Characters )
    reply_to           = ( '', string value up to 320 Characters )
    signature          = ( '', string value up to 1000 Characters )

Changing preferences can be accomplished by simply sending the preference(s) that you want to change, and the new value.

    $gmail->update_prefs( indicators => 0, reply_to => 'test@test.com' );

To delete display_name, reply_to, or signature simply send a blank string as in the following example.

    $gmail->update_prefs( signature => '' );

  STARRING A MESSAGE
To star or unstar a message use these examples

    #star
    $gmail->edit_star( action => 'add', 'msgid' => $msgid );

    #unstar
    $gmail->edit_star( action => 'remove', 'msgid' => $msgid );

  ARCHIVING
To archive or unarchive a message use these examples

    #archive
    $gmail->edit_archive( action => 'archive', 'msgid' => $msgid );

    #unarchive
    $gmail->edit_archive( action => 'unarchive', 'msgid' => $msgid );

  RETRIEVING MESSAGE LISTS
By default, get_messages returns a reference to an AoH with the messages from the 'all' folder. To change this behavior you can either send a label

    my $messages = $gmail->get_messages( label => 'work' );

Or request a Gmail provided folder using one of the provided variables

    'INBOX'
    'STARRED'
    'SPAM'
    'TRASH'

    Ex.

    my $messages = $gmail->get_messages( label => $Mail::Webmail::Gmail::FOLDERS{ 'INBOX' } );

The Array of hashes is in the following format

    $indv_email{ 'id' }
    $indv_email{ 'new' }
    $indv_email{ 'starred' }
    $indv_email{ 'date_received' }
    $indv_email{ 'sender_email' }
    $indv_email{ 'subject' }
    $indv_email{ 'blurb' }
    @{ $indv_email{ 'labels' } }
    @{ $indv_email{ 'attachments' } }

  SPACE REMAINING
Returns a scalar with the amount of MB remaining in you account.

    my $remaining = $gmail->size_usage();

If called in list context, returns an array as follows. [ Used, Total, Percent Used ] [ "0 MB", "1000 MB", "0%" ]

  INDIVIDUAL MESSAGES
There are two ways to get an individual message:

    By sending a reference to a specific message returned by get_messages

    #prints out the message body for all messages in the starred folder
    my $messages = $gmail->get_messages( label => $Mail::Webmail::Gmail::FOLDERS{ 'STARRED' } );
    foreach ( @{ $messages } ) {
        my $message = $gmail->get_indv_email( msg => $_ );
        print "$message->{ $_->{ 'id' } }->{ 'body' }\n";
    }

    Or by sending a message ID and Label that the message resides in

    #retrieve specific email message for review
    my $msgid = 'F000000000';
    my $message = $gmail->get_indv_email( id => $msgid, label => 'label01' );
    print "$message->{ $msgid }->{ 'body' }\n";

returns a Hash of Hashes containing the data from an individual message in the following format:

Hash of messages in thread by ID

    $indv_email{ 'id' }
    $indv_email{ 'sender_email' }
    $indv_email{ 'sent' }
    $indv_email{ 'to' }
    $indv_email{ 'read' }
    $indv_email{ 'subject' }
    @{ $indv_email{ 'attachments' } }

    #If it is the main message in the thread
    $indv_email{ 'body' }
    %{ $indv_email{ 'ads' } } = (
        title       => '',
        body        => '',
        vendor_link => '',
        link        => '', );

  MIME MESSAGES
This will return an individual message in MIME format.

    The parameters to this function are the same as get_indv_email.

    #prints out the MIME format for all messages in the inbox
    my $messages = $gmail->get_messages( label => $Mail::Webmail::Gmail::FOLDERS{ 'INBOX' } );
    foreach ( @{ $messages } ) {
        my $message = $gmail->get_mime_email( msg => $_ );
        print $message
    }

    returns a string that contains the MIME formatted email.

  RETRIEVING CONTACTS
The get_contacts method returns a reference to an AoH with all of the Contacts. This can be limited to the 'Frequently Mailed' contacts with a flag:

    my $contacts = $gmail->get_contacts( frequent => 1 );

The Array of hashes is in the following format

    $indv_contact{ 'id' }
    $indv_contact{ 'name1' }
    $indv_contact{ 'name2' }
    $indv_contact{ 'email' }
    $indv_contact{ 'note' }

  SENDING MAIL
The basic format of sending a message is

    $gmail->send_message( to => 'user@domain.com', subject => 'Test Message', msgbody => 'This is a test.' );

To send to multiple users, send an arrayref containing all of the users

    my $email_addrs = [
        'user1@domain.com',
        'user2@domain.com',
        'user3@domain.com', ];
    $gmail->send_message( to => $email_addrs, subject => 'Test Message', msgbody => 'This is a test.' );

You may also send mail using cc and bcc.

To attach files to a message

    $gmail->send_message( to => 'user@domain.com', subject => 'Test Message', msgbody => 'This is a test.', file0 => ["/tmp/foo"], file1 => ["/tmp/bar"] );

  DELETE MESSAGES
Use the following to move a message to the trash bin

    $gmail->delete_message( msgid => $msgid, del_message => 0 );

To permanently delete a message, just send a msgid

    $gmail->delete_message( msgid => $msgid );

  ACTING ON MULTIPLE MESSAGES
To act on multiple messages at once send an array ref containing all of the message IDs you with to act on. This is useful because Gmail may temporarily ban you if you send too much traffic in a short amount of time (for instance deleting all of the messaging in your SPAM folder one at a time).

    ### Delete Many Messages at once ###
    $gmail->delete_message( msgid => \@msgids, search => 'spam', del_message => 1 );

    ### Applying a label to multiple messages at once ###
    $gmail->edit_labels( label => 'label_name', action => 'add', msgid => \@msgids );

  GETTING ATTACHMENTS
There are two ways to get an attachment:

    By sending a reference to a specific attachment returned by get_indv_email

    #creates an array of references to every attachment in your account
    my $messages = $gmail->get_messages();
    my @attachments;

    foreach ( @{ $messages } ) {
        my $email = $gmail->get_indv_email( msg => $_ );
        if ( defined( $email->{ $_->{ 'id' } }->{ 'attachments' } ) ) {
            foreach ( @{ $email->{ $_->{ 'id' } }->{ 'attachments' } } ) {
                push( @attachments, $gmail->get_attachment( attachment => $_ ) );
                if ( $gmail->error() ) {
                    print $gmail->error_msg();
                }
            }
        }
    }

    Or by sending the attachment ID and message ID

    #retrieve specific attachment
    my $msgid = 'F000000000';
    my $attachid = '0.1';
    my $attach_ref = $gmail->get_attachment( attid => $attachid, msgid => $msgid );

Returns a reference to a scalar that holds the data from the attachment.

SAMPLE GMAIL OUTPUT
