Mail::Cap(3pm) User Contributed Perl Documentation Mail::Cap(3pm)
NAME
Mail::Cap - understand mailcap files
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');
DESCRIPTION
Parse mailcap files as specified in "RFC 1524 --A User Agent
Configuration Mechanism For Multimedia Mail Format Information>. In the
description below $type refers to the MIME type as specified in the
"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.
METHODS
Constructors
Mail::Cap->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'
filename => FILENAME
Add the specified file to the list to standard locations. This
file is tried first.
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.
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');
Run commands
These methods invoke a suitable program presenting or manipulating the
media object in the specified file. They all return 1 if a command was
found, and 0 otherwise. You might test $? for the outcome of the
command.
$obj->compose($type, $file)
$obj->edit($type, $file)
$obj->print($type, $file)
$obj->view($type, $file)
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 "undef" if no
suitable specification exists.
$obj->composeCmd($type, $file)
$obj->editCmd($type, $file)
$obj->printCmd($type, $file)
$obj->viewCmd($type, $file)
Look-up definitions
Methods return the corresponding mailcap field for the type.
$obj->description($type)
$obj->field($type, $field)
Returns the specified field for the type. Returns undef if no
specification exists.
$obj->nametemplate($type)
$obj->textualnewlines($type)
$obj->x11_bitmap($type)
