HTML::FromMail::Field - output a header field as HTML


   is a HTML::FromMail::Page
   is a HTML::FromMail::Object
   is a Mail::Reporter



Extends "DESCRIPTION" in HTML::FromMail::Page.


Extends "METHODS" in HTML::FromMail::Page.

$obj->addressField(FIELD, HOW, ARGS)

Produce text for a header field containing addresses. HOW this is done is defining the result. Possible values are 'ADDRESS', 'PHRASE', 'PLAIN', 'MAILTO', or 'LINK'. See "address HOW" for details.

$obj->fromHead(HEAD, NAME, ARGS)

Returns the fields from the header with NAME. Some fields appear more than once, some may not be present.

$obj->htmlAddresses(FIELD, ARGS)

Returns an array with address info.


Produce the body of the field: everything after the first colon on the header line.

 -Option --Default
  address  'MAILTO'
  content  <depends>
  wrap     78

See "address HOW"


How to included the body of the field. If a wrap is defined, then REFOLD is taken as default, otherwise DECODED is the default. See "content HOW"

wrap => INTEGER

In combination with content REFOLD, it specifies the maximum number of characters requested per line. See "wrap INTEGER".


Returns the name of the header field.

 -Option  --Default
  capitals  'UNCHANGED'

Overrules the default from new(settings) names. See "names HOW".

$obj->lookup(LABEL, ARGS)

Inherited, see "METHODS" in HTML::FromMail::Page

 -Option  --Defined in            --Default
  settings  HTML::FromMail::Object  {}
  topic     HTML::FromMail::Object  'field'
settings => HASH-OF-HASHES
topic => STRING



You can specify the following settings in HTML::FromMail::new(settings) for topic field:

address HOW

Some fields are pre-defined to contain e-mail addresses. In many web-based clients, you see that these addresses are bluntly linked to, but you here have a choice. As example, the header field contains the address "My Name" <>

The possible settings for this parameter are

  • 'PLAIN'

    Show the address as was specified in the message header, without smart processing. "My Name" < >

  • 'PHRASE'

    According to the standards, the phrase is ment to represent the user in an understandable way. Usually this is the full name of the user. No link is made. My Name


    Only show the address of the users.

  • 'MAILTO'

    Create a link behind the phrase. In case there is no phrase, the address itself is displayed. This is the most convenient link, if you decide to create a link. <a href="">My Name </a> <a href=""> </a>

  • 'LINK'

    Often seen, but more for simplicity of implementation is the link under the address. The 'MAILTO' is probably easier to understand. "My Name" <a href=""></a> <a href=""></a>

content HOW

Defined HOW field bodies are handled, by default UNFOLDED. Valid values are


Included the content FOLDED as found in the source message. This is the fastest choice, and usually in a preformatted html block, otherwise the folding will be lost again.


Do not accept the folding as found in the message headers, but force it into the wrap which is defined by wrap.


All line folding is removed from the field. This useful when the field body is displayed in a proportional font.


Fields may be character-set encoded. Decoding these fields is nicest, but consumes considerable time.

names HOW

Defines HOW field names are displayed: either 'WELLFORMED' or 'UNCHANGED'. Field names have a certain capitization (as defined by the message), but this may be different from the preferred use of capitals. The correct use of capitals is implemented by Mail::Message::Field subroutine wellformedName and will be used when WELLFORMED is selected. By default, the names are displayed UNCHANGED.

. Example: using HTML::FromMail::Format::Magic

  <!--{name capitals => WELLFORMED}-->


Used in combination with content REFOLD, to specify how many characters are requested per line.
