        user => 'foo',
        password => 'bar',
 );

 my $lj = LiveJournal->new(\%info);

This module is implements the LiveJournal protocol. See http://www.livejournal.com/developer/protocol.bml for details. Data is requested from the server through mode lines. Many methods return a hash reference containing key/value pairs returned by the server. Descriptions of possible responses can be found at http://www.livejournal.com/developer/modelist.bml

new (INFO)

This is the constructor for a new LiveJournal object. CWINFO is a hash containing at least username and password (plaintext) or hpassword (MD5 hash) key/value pairs. You may also include a URL, for which the default is http://www.livejournal.com/cgi-bin/log.cgi. To use a proxy, add a proxy key and value.

LiveJournal::livejournal->new([ FILES ])

If you want to use a file in the livejournalrc format to store your data, you can use this method instead. CWFILES is an array reference to the file(s) you want to load. If you don't specify any, it will use the first one found of ~/.livejournalrc, ~/.livejournal.rc, or /etc/livejournalrc. This will return an object in the LiveJournal class.

login ([ INFO ])

Log in to the LiveJournal server. Returns a hash reference. The server returns whether the password is good or not, the user's name, an optional message to be displayed to the user, and the list of the user's friend groups. CWINFO is an optional hash reference containing the optional keys getmoods, getmenus, and getpickws. getmoods should exist and be the number of the highest mood ID you have cached/stored on the user's computer. For example, if you logged in last time with and got mood IDs 1, 2, 4, and 5, then send 5 as the value of getmoods. The server will return every new mood that has an internal MoodID greater than 5. If you've never downloaded moods before, send 0. getmenus should exist if you want to get a list/tree of web jump menus to show in your client. getpickws should exist if you want to receive that list of picture keywords.

user ()

Returns the username

password ()

Returns the password or hpassword, whichever is set.

version ([VERSION])

Returns the version string. You may alter the version string by passing a CWVERSION.

access ([ INFO ])

Sets/returns the journals that the user has the ability to post to. This method is called automatically by CWparse_login(). It returns a list reference containing each journal.

friend_group ([ INFO ])

Sets/returns the friend group information. This method is called automatically by CWparse_login(). It returns a hash of hashes containing name and sortorder key/value pairs. We use a hash instead of an array here because the group numbers start from 1 and it seemed more appropriate than having an undef 0 element or requiring adding 1 all the time.

friend_group_max ([ MAX ])

Sets/returns the maximum friend_group number. This method is called automatically by CWparse_login().

menu ([ INFO ])

Sets/returns the menu text and URL information. This method is called automatically by CWparse_login(). You can use the list of lists of hashes it returns as data for menus.

mood ([ INFO ])

Sets/returns the mood information. This method is called automatically by CWparse_login(). Returns a list of hashes containing the keys id and name for each mood.

mood_count ([ COUNT ])

Sets/returns the number of moods. This method is called automatically by CWparse_login().

name ([ NAME ])

Sets/returns the name of the the logged in user. This method is called automatically by CWparse_login().

pic_keyword ([ KEYWORDS ])

Sets/returns the picture keywords. This method is called automatically by CWparse_login(). Returns a reference to a list of the keywords.

escape (STRING)

Use this method to escape strings. CWSTRING is any string. All non-alphanumeric characters and non-whitespace are converted to their CW%hex values. Spaces are converted to +s.

check ()

Poll the server to see if the friends list has been updated. This request is extremely quick, and is the preferred way for users to see when their friends list is updated. Returns a hash reference.

get ([ [ FRIENDOF ] [, GROUPS ] ])

Takes two optional arguements. If CWFRIENDOF is set to 1, you will also get back the info from the friendof mode. If CWGROUPS is set to 1, you will get the info from the getfriendgroups mode. This method returns a hash reference which should be passed to BIparse() to be more useful. YOU SHOULD ALWAYS USE THIS METHOD BEFORE VIEWING AND AFTER MODIFYING YOUR FRIENDS LIST TO AVOID INCONSISTENCIES.

parse (FRIENDS)

Takes one arguement: the hash reference returned from BIget(). Returns a hash of lists of hashes containing the info (user, name, fg, bg, etc) for each friend such as: 'friend' => [ { 'fg' => '#000000', 'bg' => '#FFFFFF', 'groupmask' => '3', 'user' => 'SomeUser', 'name' => 'Some X. Name' } ] You should call BIparse() anytime you call BIget() to keep your friend count up to date.

edit (FRIENDS)

This method is used to add and edit friends to your friends list. It takes a hash of hash references structure which has the username as the first level of keys. The second level contains optional fg and bg colors in #RRGGBB format. 'newfriend' => { 'fg' => '#000000', 'bg' => '#FFFFFF', } newfriend is the name of the new user. number should be the sum of CWnumfriends() + n where n is incremented for each friend you are adding.

add (FRIEND, [ FG [, BG ] ])

Use this method to add a user from your friends list. CWFRIEND is a username. CWFG and CWBG are foreground and background values in #RRGGBB format.

remove (USERS)

Use this method to remove users from your friends list. Pass it an array reference containing usernames. Returns a hash reference.

friendof ()

This method returns a hash reference of the users that list you as a friend. This hash reference can be passed to BIparse().

lastupdate ([ LAST ])

Returns or sets the last time check was used. BIcheck() sets this value so you don't have to.

numfriends ([ NUMBER ])

This method sets and returns the number of friends you have. It is automatically called from BIparse() so you shouldn't have to worry about setting it manually.

friends ()

Sets and returns your friends list. This method is called by CWparse() automatically to propagate the hash.

getgroups ()

This method returns a hash reference containing information about your friend groups

editgroups (INFO)

Use this method to create or edit a friend group. You can modify the name, sort order, and public attributes of the group by passing a hashref containing the keys called name, sort, or public and respective new values. You can also add a friend to a group or groups by passing their username as a key and the new groupmask as a value.

deletegroups (NUMBERS)

This method deletes a friend group. Pass it an array reference containing the numbers of the groups to delete.

friends_by_group ()

Returns a hash of list references containing users and the groups they are members of.

add_friend_to_group (USER, GROUP)

Use this method to add a friend to a user group. CWUSER is the username of the person and CWGROUP is the group number.

remove_friend_from_group (USER, GROUP)

Use this method to remove a friend from a user group. CWUSER is the username of the person and CWGROUP is the group number.

get (INFO)

Use this method to download parts of a user's journal. CWINFO is a hash reference containing at least a key called selecttype and a value of either syncitems, day, lastn, or one. syncitems will use the CWlastcync() method by default, otherwise pass it a date in the yyyy-mm-dd hh::mm::ss format. If you use day, you may provide year, month, and day keys to specify which day. Default is today. The lastn value requires a howmany key which says how many of the most recent items to download. Maximum is 50. Default is 20. If you want a particular entry, you should use the one value and a complimentary itemid key containing the id of the item you want to grab. For further detail, see http://www.livejournal.com/developer/modeinfo.bml?getevents

post (INFO)

This method is used to post a journal entry. CWINFO is a hash reference containing at least an event key with a value of the post content. The date keys are created for you. For further detail, see http://www.livejournal.com/developer/modeinfo.bml?postevent

edit (INFO)

Used to edit user's past journal entry. CWINFO is a a hash reference containing at least the itemid and event being submitted. Other optional values are documented at http://www.livejournal.com/developer/modeinfo.bml?editevent

remove (ITEMID)

Used to delete a past journal entry. CWITEMID is a scalar containing the unique item id to delete.

syncitems ()

Returns a hash reference containing items (journal entries, to-do items, comments) that have been created or updated on LiveJournal since you last downloaded them.

lastsync ([ LAST ])

Returns or sets the last time BIsyncitems() was used. BIsyncitems() sets this value so you don't have to.

getdaycounts ()

This mode retrieves the number of journal entries per day. Useful for populating calendar widgets in GUI clients.
