SYNOPSIS
DESCRIPTION
THIS MODULE IS UNDER CONSTRUCTION. However, a lot of things already work. Best take a look at the examples directory.
Extends "DESCRIPTION" in HTML::FromMail::Page.
METHODS
Extends "METHODS" in HTML::FromMail::Page.
- $obj->createAttachment(MESSAGE, PART, ARGS)
-
Create an attachment file, and return a hash with information about that file. Returns
undef
if creation fails.This method is used by htmlAttach() and htmlPreview() to create an actual attachment file. It defines
url
,size
andtype
tags for the template.-Option--Default outdir <required>
- $obj->disposition(MESSAGE, PART, ARGS)
-
Returns a string, which is either
inline
,attach
, orpreview
, which indicates how the part of the message should be formatted. This can be changed with settingdisposition
. - $obj->fields()
-
Returns the field text producing object.
- $obj->header()
-
Returns the header text producting object.
- $obj->htmlAddresses(MESSAGE, ARGS)
-
Produce data about addresses which are in the field. This method uses HTML::FromMail::Field::htmlAddresses() for that.
- $obj->htmlAttach()
-
The
attach
container definesurl
,size
andtype
tags for the template.example: using HTML::FromMail::Format::Magic
<!--{message}--> <!--{attach}--> <!--{/attach}--> <!--{/message}-->
- $obj->htmlBody(MESSAGE, ARGS)
-
Produce the body of a field. This tag can only be used inside a field container. See HTML::FromMail::Field::htmlBody() for the use and options.
- $obj->htmlField(MESSAGE, ARGS)
-
Returns the field definition for the currently active message part. When the formatter sees this is a final token, then only the body of the field is returned (and the options of HTML::FromMail::Field::htmlBody() are accepted as well). Otherwise, the information about the field is captured to be used later.
-Option--Default decode <true> if possible from PART name <required>
- decode => BOOLEAN
- from => PART|PARENT|MESSAGE
-
The source of this field: the currently active PART (which may be the main message), the PARENT of the active part (defaults to the message), or the main MESSAGE itself.
- name => STRING
example: using HTML::FromMail::Format::Magic
<!--{field name => To, content => REFOLD, wrap => 20}--> <!--{field name => To}--> <!--{name capitals => WELLFORMED}--> <!--{body wrap => 30}--> <!--{/field}-->
- $obj->htmlForeachPart(MESSAGE, ARGS)
-
Produces html for the parts of a multipart mesasge body. Each part may be a multipart too. For each part, the
message
container code is applied recursively.This container defines a
part_number
, and enables the use of thepart
tag.example: using HTML::FromMail::Format::Magic
<!--{message}--> <!--{multipart}--> <ul> <!--{foreachPart}--> <li>This is part <!--{part_number}--> <!--{part}--> </li> <!--{/foreachPart}--> </ul> <!--{/multipart}--> <!--{message}-->
- $obj->htmlHead(MESSAGE, ARGS)
-
Defines the fields of a header. The options are provided by HTML::FromMail::Head::fields().
example: using HTML::FromMail::Format::Magic
# simple <pre><!--{head}--></pre> # complex <table> <!--{head remove_spam_groups => 0}--> <tr><td><!--{name}--></td> <td><!--{body}--></td></tr> <!--{/head}--> </table>
- $obj->htmlInline()
-
-Option--Default type ''
- type => MIME-TYPE
-
Selects the MIME types which are handled by this singlepart block. You can specify the types as defined by MIME::Type subroutine equal.
example: using HTML::FromMail::Format::Magic
<!--{message}--> <!--{inline type => text/html}--> <!--{html}--> <!--{/inline}--> <!--{/message}-->
- $obj->htmlMessage(MESSAGE, ARGS)
-
Encapsulated code which is producing the message, which may be a multipart. You have to defined the message block when you use the part (see htmlPart()) tag. If you do not use that, you do not need this.
example: using HTML::FromMail::Format::Magic
<!--{message}--> <!--{inline}-->This is an inlined singlepart<!--{/inline}--> <!--{attach}-->This is an attachment<!--{/attach}--> <!--{preview}-->An attachment with preview<!--{/preview}--> <!--{multipart}-->This is a multipart<!--{/multipart}--> <!--{nested}-->message/rfc822 encapsulated<!--{/nested}--> <!--{/message}-->
- $obj->htmlMultipart(MESSAGE, ARGS)
-
Encapsulates text to be produced when the message(-part) is a multipart.
- $obj->htmlName(MESSAGE, ARGS)
-
Produce the name of a field. This tag can only be used inside a field container. See HTML::FromMail::Field::htmlName() for the use and options.
- $obj->htmlNested(MESSAGE, ARGS)
-
Contains text to be produced when the message(-part) is a nested message; encapsulated in a message/rfc822.
- $obj->htmlPart(MESSAGE, ARGS)
-
Apply the
message
container of the current part on its data. See example in htmlForeachPart(). - $obj->htmlPreview()
-
-Option--Default type ''
- type => MIME-TYPE
-
Selects the MIME types which are handled by this singlepart block. You can specify the types as defined by MIME::Type subroutine equal.
The
preview
container definesurl
,size
andtype
tags for the template, which describe the attachment file. Besides, it preview defines a tag which tells whether the preview is made ashtml
or asimage
. Within anhtml
block, you will get an extratext
which includes the actual html preview text.The
image
container provides more tags:smallurl
,smallwidth
,smallheight
,width
, andheight
.
example: using HTML::FromMail::Format::Magic
<!--{message}--> <!--{preview}--> <!--{html}--> <!--{text}--> <!--{/html}--> <!--{image}--> <img src="<!--{smallurl}-->" width="<!--{smallwidth}-->" height="<!--{smallheight}-->"><br /> (real is <!--{width}--> x <!--{height}-->) <!--{/image}--> <a href="<!--{url}-->">Attachment of <!--{type}--> (<!--{size}--> bytes)</a> <!--{/preview}--> <!--{/message}-->
- $obj->htmlRawText(MESSAGE, ARGS)
-
Returns the plain text of the body.
- $obj->htmlSubject(MESSAGE, ARGS)
-
Get the subject field from the message's header, just a short-cut for specifying htmlField(name) with
subject
.example: using HTML::FromMail::Format::Magic
<!--{subject}--> # message subject <!--{field name => subject}--> # part's subject <!--{field name => subject, from => MESSAGE}--> # message subject
- $obj->htmlifier(MIME-TYPE)
-
Returns the code reference for a routine which can create html for the objects of the specified MIME-TYPE. The TYPE may be a (smartly overloaded) MIME::Type object. The behaviour can be changed with the
htmlifiers
setting. - $obj->lookup(LABEL, ARGS)
-
Inherited, see "METHODS" in HTML::FromMail::Page
- HTML::FromMail::Message->new(OPTIONS)
-
-Option --Defined in --Default settings HTML::FromMail::Object {} topic HTML::FromMail::Object 'message'
- $obj->previewer(MIME-TYPE)
-
Returns the code reference for a routine which can create a preview for the objects of the specified MIME-TYPE. The TYPE may be a (smartly overloaded) MIME::Type object. The behaviour can be changed with the
previewers
setting.
DETAILS
Settings
You can specify the following settings in HTML::FromMail::new(settings) for topic message
:
disposition CODE
Message parts have to be displayed. There are a few ways to do that: by inline
, attach
, and preview
. In the first case, the text of the part is inserted in the main page, in the other two as link to an external file. The latter is creating a small preview of the attachement.
The message may provide an indication of the way the part should be displayed in the Content-Disposition
field. For many reasons, an exception will be made... for instance, binary messages will never be inlined. You can create your own code reference to change the behavior of the default algorithm.
. Example: of own disposition rules
my $f = HTML::FromMail->new
( settings =>
{ message => { disposition => \&my_disposer }
}
);
sub my_disposer($$$$$)
{ my ($obj, $message, $part, $suggestion, $args) = @_;
return 'attach'
if $suggestion eq 'inline' && $part->size > 10_000;
$suggestion;
}
previewers ARRAY-OF-PAIRS
For some kinds of message parts, previews can be produced. This ordered list of PAIRS contains mime type with code reference combinations, each describing such a production. The specified items are added before the default list of preview generators. An undef
as code reference will cause the default preview producer to be disabled.
Method previewer() is called when a previewer for a certain content type has to be looked-up. The default previewers are defined (and implemented) in HTML::FromMail::Default::Previewers.
htmlifiers ARRAY-OF-PAIRS
Some kinds of information can be translated into HTML. When a data type defines such a translation, it may be inlined (see htmlInline()), where in other cases it will get attached. The usage is the same as for the previewers
option.
Method htmlifier() is called when a htmlifier for a certain content type has to be looked-up. The default htmlifiers are defined (and implemented) in HTML::FromMail::Default::HTMLifiers.
. Example: use own converters
my @prevs = ( 'text/postscript' => \&prepost
, 'image' => \&imagemagick
);
my @html = ( 'text/html' => \&strip_html
, 'text/plain' => \&plain2html
);
my $f = HTML::FromMail->new
( settings =>
{ message => { previewers => \@prevs
, htmlifiers => \@html
, disposition => \&my_disposer
}
}
);
sub prepost($$$$$)
{ my ($page, $message, $part, $attach, $args) = @_;
# args contains extra info from template
# returns a hash of info which is used in a
# preview block (see htmlPreview())
}
