Page Layout

The section describes the layout of the pages created by MHonArc. Each page's layout is controled by resources (see Section Resources). Layout resources can be changed as you see fit to achieve the appearence you desire for your mail archives.

Notation

To simplify the description of the various pages created by MHonArc, the following notation is used:

( ): Parentheses denote a group of resources.
|: The vertical bar is use within a group to denote a boolean OR. For example, "(X | Y | Z)" states that either X, Y, or Z may apply.
?: Denotes that preceding resource, or group, is optional.
*: Denotes that preceding resource, or group, can occur zero or more times.
+: Denotes that preceding resource, or group, can occur one or more times.

Main Index Page

The main index is normally the default index of an archive. The main index list messages by date, subject, author, or message number. Since date listing is the default, the main index is commonly referred to as the date index.

Thread Index Page

The thread index list messages by thread. Threads are based upon In-Reply-To and References fields of messages and by same Subjects.

The layout of a thread index page is more complicated than the main index layout since threading is more complex. Also, MHonArc tries to provide the greatest flexibility for customizing thread listing layout.

If the previous is not confusing enough, there are four other resources for controlling the thread index page layout: TCONTBEGIN, TCONTEND, TINDENTBEGIN, TINDENTEND. If the multiple page resource is set, it is possible that a thread can span more than one page. These resources are used to restart a thread that has been clipped due to a page boundary.

Message Page

The message page contains a single message converted to HTML and archive navigational links.

NOTE

If the SINGLE resource is set, TOPLINKS and BOTLINKS are are not applicable. If the FOLREFS is off, FOLUPBEGIN, FOLUPLITXT, FOLUPEND, REFSBEGIN, REFSLITXT, and REFSEND resources are not applicable.

Message pages also contain comment declarations. Some of the comment declarations are vital markers to allow MHonArc to properly edit the message when needed during updates.

Converted message header

The format of converted message headers are determined by the following resource layout:

FIELDSBEG
    (LABELBEG
     label text
     LABELEND
     FLDBEG
     field text
     FLDEND)*
FIELDSEND

NOTE

The line breaks above are used to show the sequence order of the resources and do not indicate any actual line breaks in the final markup generated.

Converted message body

The formatting of message body data is controled by filter routines. See the MIMEFILTERS resource page for more information.

Thread slices

MHonArc supports the ability to include thread listings on messages pages via the $TSLICE$ resource variable. The formatting of the $TSLICE$ resource variable is controled by the following resources: TSLICEBEG, TSLICECONTBEG, TSLICECONTEND, TSLICEEND, TSLICEINDENTBEG, TSLICEINDENTEND, TSLICELIEND, TSLICELIENDCUR, TSLICELINONE, TSLICELINONEEND, TSLICELITXT, TSLICELITXTCUR, TSLICESINGLETXT, TSLICESINGLETXTCUR, TSLICESUBJECTBEG, TSLICESUBJECTEND, TSLICESUBLISTBEG, TSLICESUBLISTEND, TSLICETOPBEG, TSLICETOPBEGCUR, TSLICETOPEND, and TSLICETOPENDCUR

The structure of the resources parallels the thread resource layout structure described for the thread index page, and the above thread slice resources will default to the corresponding non-tslice resources, allowing you to provide a consistent look to all thread listings without having to define two sets of resources.

One key difference to the TSLICE* resources is the ability to customize the look for current message item in the the slice listing. I.e. You can actually highlight, grey-out, etc, the current message to give the reader a visual cue of where they are in the thread. See TSLICETOPBEGCUR for an example.
