IO::Maildir provides functions for safely dealing with maildir directories.


use IO::Maildir;
my $inbox = maildir "~/mail/INBOX";
my $msg = $inbox.receive($somemail);


IO::Maildir tries to implement the maildir spec. It can serve as a basis for mail delivery agents or mail user agents (or a mixture of both). The named agent parameter can be used to set the behaviour for some methods. Default behaviour can be changed by setting $maildir-agent.

sub maildir

sub maildir($path --> IO::Maildir)

Returns a maildir object from $path. $path will be coerced to IO.


our Agent $maildir-agent = IO::Maildir::DELIVERY

Set this to either IO::Maildir::DELIVERY or IO::Maildir::USER. Affects behaviour of following methods:

class IO::Maildir

Class for maildir directories.

my $maildir = IO::Maildir.new "~/Mail/INBOX";
my $maildir = maildir "~/Mail/INBOX" # Same

method create

method create( --> IO::Maildir) { ... }

Creates a new maildir directory including its cur, new and tmp subdirectories.

method receive

multi method receive($mail --> IO::Maildir::File) { ... }

Adds a new file to the maildir. receive will always deliver to new and write the file to tmp first if neccessary. $mail may be of any type which is accepted by IO::Path.spurt, which are any Cool or Blob types.

Up to version 0.0.2 receiving an IO object would delete the original file. This behaviour was fixed and the original file now remains after receiving.

method walk

method walk(:$all, :$agent = $maildir-agent --> Seq) { ... }

Returns the new mails in the maildir (or all if you set it). Newest mails will be returned first.

If called with $agent = IO::Maildir::USER it will also do the following actions:

class IO::Maildir::Files

Handle for files inside a maildir.

#Create from IO::Path
my $file = IO::Maildir::File.new( path => "~/Mail/INBOX/cur/uniquefilename:2,".IO );
#Create from maildir
my $file = IO::Maildir::File.new( dir => $maildir, name => "uniquefilename:2," );

Usually you don't need to do anything of the above, since you will receive your IO::Maildir::File objects from IO::Maildirs methods.

attribute dir

has IO::Maildir $.dir

Points to the maildir containing this file.

attribute name

has $.name

Complete file name including flags and stuff.

method IO

method IO( --> IO ) { ... }

Returns the IO::Path object pointing to the file.

method flags

method flags( --> Set ) { ... }

Returns the Set of flags set for this file.

method flag

multi method flag(:$agent = $maildir-agent, *%flags)
multi method flag(
    %flags where *.keys.Set ⊆ <P R S T D>.Set,
    :$agent = $maildir-agent)

Use this to set flags. Fails if $agent is set to IO::Maildir::DELIVERY. This will also move the file to cur, because it has been seen by the MUA.

method move

multi method move(IO::Maildir $maildir, Agent :$agent = $maildir-agent --> IO::Maildir::File) { ... }
multi method move (IO $iodir, Agent :$agent = $maildir-agent --> IO::Maildir::File) { ... }

Moves the file to a different maildir and returns the updated file-handle. If called in IO::Maildir::DELIVERY mode, the file will be moved to new and old flags will be removed. If called in IO::Maildir::USER mode, it will be moved to cur and flags will be preserved.
