Usage

Here's a quick rundown of how to use this library. For specifics, see the generated RDoc.

Examples

Print the list address for all lists in a directory:

Ezmlm.each_list( '/lists' ) do |list|
	puts list.address
end

Check if I'm subscribed to a list, and if so, unsubscribe:

(You don't really have to check first, subscribe and unsubscribe are idempotent.)

list = Ezmlm::List.new( '/lists/waffle-lovers' )

if list.include?( 'mahlon@martini.nu' )
	list.unsubscribe( 'mahlon@martini.nu' )
end

puts "The list now has %d subscribers!" % [ list.subscribers.size ]

Iterate over the subscriber list:

list.subscribers.each do |subscriber|
	# ...
end

Make the list moderated, and add a moderator:

list.moderated = true
list.add_moderator( 'mahlon@martini.nu' )
list.moderated? #=> true

All other list behavior tunables operate in a similar fashion, see RDoc for details.

Archiving!

All of the archival pieces take advantage of Ezmlm-IDX extensions. If you want to use these features, you'll want to enable archiving and indexing for your lists, using the -a and -i flags to ezmlm-make. (Enabling archiving with this library also enables indexing and thread indexes, I assume that since you're using ezmlm-idx, you want these enhancements!)

list.archived? #=> false
list.archived = true
list.archived? #=> true

If your list(s) already had archiving enabled (the default to ezmlm-make) but not indexing, you can manually run ezmlm-archive to rebuild the necessary files - afterwards, they are kept up to date automatically.

How many messages are in the archive?:

list.message_count #=> 123

Fetch message number 100 from the archive:

message = list.message( 100 ) or abort "No such message."

puts message.subject
puts message.body.to_s # Print just the body of the message.
puts message.to_s      # Print the entire, unparsed message.

thread = message.thread # Returns an Ezmlm::List::Thread object
author = message.author # Returns an Ezmlm::List::Author object

As a general rule, methods called on the Ezmlm::List object return nil if they are unable to perform the requested task. Instantiating the underlying objects directly raise with a specific error. The following are equivalent, but behave differently:

message = list.message( 10000 ) # nonexistent message, returns nil
message = Ezmlm::List::Message.new( list, 10000 ) # Raises a RuntimeError 

Message objects act as "Mail" objects from the excellent library from Mikel Lindsaar (https://github.com/mikel/mail). See its documentation for specifics.

Iterate over messages in a specific thread:

Messages know what thread they belong to. Once you have a thread object from a message, it is an enumerable. Iterate or sort on it using standard Ruby methods.

thread.each do |message|
	# ...
end

Threads are also aware of who participated in the conversation, via the 'authors' and 'each_author' methods.

Iterate over messages from a specific author:

Messages know who authored them. Once you have an author object from a message, it is an enumerable. Iterate or sort on it using standard Ruby methods.

author.each do |message|
	# ...
end

An Author object is also aware of all threads the author participated in, via the 'threads' and 'each_thread' methods.
