=encoding utf8 =head1 NAME Mail::Cap - understand mailcap files =head1 SYNOPSIS my $mc = Mail::Cap->new; my $desc = $mc->description('image/gif'); print "GIF desc: $desc\n"; my $cmd = $mc->viewCmd('text/plain; charset=iso-8859-1', 'file.txt'); =head1 DESCRIPTION Parse mailcap files as specified in "RFC 1524 --A User Agent Configuration Mechanism For Multimedia Mail Format Information>. In the description below C<$type> refers to the MIME type as specified in the C<Content-Type> header of mail or HTTP messages. Examples of types are: image/gif text/html text/plain; charset=iso-8859-1 You could also take a look at the File::MimeInfo distribution, which are accessing tables which are used by many applications on a system, and therefore have succeeded the mail-cap specifications on modern (UNIX) systems. =head1 METHODS =head2 Constructors =over 4 =item Mail::Cap-E<gt>B<new>(%options) Create and initialize a new Mail::Cap object. If you give it an argument it will try to parse the specified file. Without any arguments it will search for the mailcap file using the standard mailcap path, or the MAILCAPS environment variable if it is defined. -Option --Default filename undef take 'FIRST' =over 2 =item filename => FILENAME Add the specified file to the list to standard locations. This file is tried first. =item take => 'ALL'|'FIRST' Include all mailcap files you can find. By default, only the first file is parsed, however the RFC tells us to include ALL. To maintain backwards compatibility, the default only takes the FIRST. =back example: $mcap = new Mail::Cap; $mcap = new Mail::Cap "/mydir/mailcap"; $mcap = new Mail::Cap filename => "/mydir/mailcap"; $mcap = new Mail::Cap take => 'ALL'; $mcap = Mail::Cap->new(take => 'ALL'); =back =head2 Run commands These methods invoke a suitable program presenting or manipulating the media object in the specified file. They all return C<1> if a command was found, and C<0> otherwise. You might test C<$?> for the outcome of the command. =over 4 =item $obj-E<gt>B<compose>($type, $file) =item $obj-E<gt>B<edit>($type, $file) =item $obj-E<gt>B<print>($type, $file) =item $obj-E<gt>B<view>($type, $file) =back =head2 Command creator These methods return a string that is suitable for feeding to system() in order to invoke a suitable program presenting or manipulating the media object in the specified file. It will return C<undef> if no suitable specification exists. =over 4 =item $obj-E<gt>B<composeCmd>($type, $file) =item $obj-E<gt>B<editCmd>($type, $file) =item $obj-E<gt>B<printCmd>($type, $file) =item $obj-E<gt>B<viewCmd>($type, $file) =back =head2 Look-up definitions Methods return the corresponding mailcap field for the type. =over 4 =item $obj-E<gt>B<description>($type) =item $obj-E<gt>B<field>($type, $field) Returns the specified field for the type. Returns undef if no specification exists. =item $obj-E<gt>B<nametemplate>($type) =item $obj-E<gt>B<textualnewlines>($type) =item $obj-E<gt>B<x11_bitmap>($type) =back =head1 SEE ALSO This module is part of the MailTools distribution, F<http://perl.overmeer.net/mailtools/>. =head1 AUTHORS The MailTools bundle was developed by Graham Barr.
