mh-e - Customizing Scan Line Formats
Go to the first, previous, next, last section, table of contents.
The name of the program that generates a listing of one line per message
is held in mh-scan-prog (default: `"scan"'). Unless this
variable contains an absolute pathname, it is assumed to be in the
mh-progs directory. You may link another program to scan
(see mh-profile(5)) to produce a different type of listing.
If you change the format of the scan lines you'll need to tell mh-e how
to parse the new format. As you see, quite a lot of variables are
involved to do that. The first variable has to do with pruning out
garbage.
mh-valid-scan-line
-
This regular expression describes a valid scan line. This is used to
eliminate error messages that are occasionally produced by
inc or
scan (default: `"^ *[0-9]"').
Next, two variables control how the message numbers are parsed.
mh-msg-number-regexp
-
This regular expression is used to extract the message number from a
scan line. Note that the message number must be placed in quoted
parentheses, (\\(...\\)), as in the default of `"^
*\\([0-9]+\\)"'.
mh-msg-search-regexp
-
Given a message number (which is inserted in `%d'), this regular
expression will match the scan line that it represents (default:
`"^[^0-9]*%d[^0-9]"').
Finally, there are a slew of variables that control how mh-e marks up
the scan lines.
mh-cmd-note
-
Number of characters to skip over before inserting notation (default:
4). Note how it relates to the following regular expressions.
mh-deleted-msg-regexp
-
This regular expression describes deleted messages (default:
`"^....D"'). See also
mh-note-deleted.
mh-refiled-msg-regexp
-
This regular expression describes refiled messages (default:
`"^....\\^"'). See also
mh-note-refiled.
mh-cur-scan-msg-regexp
-
This regular expression matches the current message (default:
`"^....\\+"'). See also
mh-note-cur.
mh-good-msg-regexp
-
This regular expression describes which messages should be shown when
mh-e goes to the next or previous message. Normally, deleted or refiled
messages are skipped over (default: `"^....[^D^]"').
mh-note-deleted
-
Messages that have been deleted to are marked by this string (default:
`"D"'). See also
mh-deleted-msg-regexp.
mh-note-refiled
-
Messages that have been refiled are marked by this string (default:
`"^"'). See also
mh-refiled-msg-regexp.
mh-note-copied
-
Messages that have been copied are marked by this string (default:
`"C"').
mh-note-cur
-
The current message (in MH, not in mh-e) is marked by this string
(default: `"+"'). See also
mh-cur-scan-msg-regexp.
mh-note-repl
-
Messages that have been replied to are marked by this string (default:
`"-"').
mh-note-forw
-
Messages that have been forwarded are marked by this string (default:
`"F"').
mh-note-dist
-
Messages that have been redistributed are marked by this string
(default: `"R"').
mh-note-printed
-
Messages that have been printed are marked by this string (default:
`"P"').
mh-note-seq
-
Messages in a sequence are marked by this string (default: `"%"').
