Mail – view mail in acme

Mail [ –OsT ] [ –m maildir ] [ –f format ] [ –o outbox ]


Mail edits a mailbox in an acme(1) environment. The default mailbox is /mail/fs/mbox. Mail shows 3 views: The list view, the message view, and the composition view.

At startup, Mail takes the following options:
T    Disable threading
O    Disable writing to outbox
s    Accept sendmail plumb messages. By default, only the Mail instance viewing /mail/fs/mbox will accept plumb messages.
m maildir
Open the maildir maildir instead of the default
f format
Define the format of individual messages in the list view (see "Format strings" below).
o outbox
Save a copy of outgoing messages to the mailbox outbox, instead of discarding them after they're enqueued.

Mail presents and acme interface for a upas/fs mailbox. When started, a mailbox, by default /mail/fs/mbox, is presented. In the message list, the tag bar commands typically affect the selected messsage. In the message and composition views, they typically apply to the current message.

The following text commands are recognized by the message list:
Put   Flush pending changes back to upasfs(4).
Delmesg, Undelmesg
Flags a message for deletion on the next Put invocation.
NextSelect the next unread message in the mailbox.
Mark [±flags]
Add or remove message flags. The flags recognized are listed in upasfs(4)

The following text commands are recognized by the message view:
Reply [all]
Replies to a message, quoting it. If all is specified, reply to all addresses on the message.
Delmesg, Undelmesg
As with the message view, but applied to the open message.
MarkAs with the message view, but applied to the open message.

The following text commands are recognized by the composition window:
PostSends the message currently being composed.

Format strings
The formatting of messages in the list view is controlled by the format string defined through the –f flag. The format string is composed of multiple directives: plain characters, which are displayed unchanged; indentation directives, which allows spacing based on thread depth; and messages directives, which display message fields.

Directives have the following format:
% [flags] [width] verb

width limits the number of characters displayed. If width is negative, text is aligned right instead of left.

The supported flags are:
>     Insert indentation into the start of the field. This does not increase the width of the field.

Messages directives are:
s     Subject
f     From field
F     From field including sender's name
t     To field
c     Cc field
r     Reply–to field

Indentation directives are:
i     Adds spacing depending on message depth in thread but limited to a single level. If width is not specified, adds a tabulation otherwise width specifies the number of spaces to display.
I     Similar to i but not limited to a single level.

Two special directives are also available:
Text within the brackets is displayed if the message is not the toplevel message of a thread.
Text within the braces is used as the format string for tmfmt(2).

The default format string is "%>48s\t<%f>"
