- Header-Suppress: and Header-Display:
-
You control what header fields are displayed in a message with a
combination of the Header-Suppress:
and Header-Display: profile entries. Hidden fields are
just scrolled off the top of the message display window. Each
profile entry is a list of regular expression patterns
that are matched against the field. Case is not
significant in the patterns.
exmh takes three steps to decide whether or not to show a
header field.
-
By default, show all header fields.
-
If a field is in the Header-Suppress list, don't show it.
-
If a field is in the Header-Display list, show it.
Note that a pattern in Header-Display: has priority
over a pattern in Header-Suppress:. The default values
for these profile entries are:
Header-Suppress: .*
Header-Display: subject to from date cc
If you are a mail junky, you may want to use Header-Suppress to
explicitly suppress the boring header fields you already know
about. New, interesting fields inserted by random mailers will
be displayed for you to check out. In contrast, the default for
Header-Suppress hides everything; you explicitly choose fields
you want to see by setting Header-Display.
So, the effect of the default rules is to show five fields:
Subject:, To:, From:, Date:,
and cc:.
- Folder-Order:
-
The Folder-Order: entry tells exmh how to order
your folder labels in the folder display area. Each item in the
order can be either:
-
the name of a folder, or
-
a glob pattern to match on the folder names.
All folder names that match the same pattern are sorted
alphabetically. Longer pattern matches have priority over
shorter patterns.
The glob patterns use the syntax of Tcl's string match function.
It's similar to the string matching used in many shells:
* matches a sequence of any characters.
? matches any character.
The default Folder-Order: puts your inbox first:
Folder-Order: inbox *
My Folder-Order looks like:
Folder-Order: personal exmh mxedit * mail* sun m3 mach background
Folder-Order: also tells exmh the order in which
to visit folders that have unread mail. When you use Next at the
end of a folder, exmh automatically changes to the next
folder in
Folder-Order: that has unseen messages, if any. When no
more folders have unseen mail, you're changed to the first
folder in your Folder-Order: -- unless you disable this
by turning off the Cycle back to first preference setting
under the Scan Listing section.
- Folder-Unseen:
-
The Folder-Unseen: entry lets you tell exmh the
names of folders to search for unseen messages. Its value is a
set of "glob" patterns that are matched against folder names.
Note that glob has filename smarts, so you'll have to take into
account subfolders in your glob patterns. (The Chapter
Key Parts of the UNIX
Filesystem explains how MH stores folders and subfolders in
the UNIX filesystem.) For example,
-
Use inbox* to match all folders whose names begin
with inbox, but not subfolders of inbox;
-
use inbox/* to match the first level of subfolders
under inbox;
-
use inbox/*/* to match the second level; and so on.
- Folder-Ignore:
-
The Folder-Ignore: entry is a set
of patterns for folder names you want to ignore. The default
pattern is .*, which causes exmh to ignore all
directories whose names begin with a dot (.).
Your glob patterns for Folder-Ignore: must take
subfolders into account -- in the same way
as Folder-Unseen:.
- Draft-Folder:
-
The Draft-Folder: entry is the
name of a folder for messages being composed. If you don't have
a Draft-Folder: entry,
exmh asks if it may create one. The
Section Draft Folder has
more information.
- ExmhShowProc:
-
The ExmhShowProc: entry lets you
define a program that pre-filters a message before displaying
it. If ExmhShowProc: is defined, exmh runs that
program with the current message as the standard
input; exmh displays the program's standard output. Note
that the Header-Suppress: and Header-Display:
mechanisms are used even if you have a special showproc.
- Scan-Proc:
-
The Scan-Proc: entry can be used
to define an alternative
scan program. (For more information, see the
Section MH Format Strings.)
If you change the scan format, be sure that the message number
is first on each scan line and that there is at least one space
after the message number.
exmh depends on this.
- MailDrop:
-
The MailDrop: entry is required
if you don't have your system mailbox in the "standard"
location, which is typically
/usr/spool/mail/username. If you don't
define MailDrop: correctly then Inc won't do
anything because it won't find your new messages in the system
mailbox.
- Path:
-
The Path: entry is used to find
your mail folders.
exmh aborts if this entry is missing; it presumes that
you haven't set up MH properly. The
Section Changing MH Directory
Name has more information.
