1 This file lists the most important differences between mmh and nmh.
2 This list is not complete and will never be; it shall give just a
3 quick overview on what kind of changes have been made.
5 Version mmh-0.1 and nmh-1.3-dev (as of 2011-04-13) are compared.
7 References are made to docs/schnalke-mmh.pdf. Explanations are to be
8 found there. For a detailed list of changes see the VCS changelog.
9 To find out how to use the mmh tools, have a look at the man pages.
14 *) All network transfer facilities have been removed. There is no MTS
15 (SMTP client) anymore and no POP client. An MSA/MTA is required to
16 send mail. An MRA is required to retrieve mail via POP/IMAP. (Sec.
18 *) ~/.mh_profile was moved to ~/.mmh/profile. All configuration files
19 in the mail storage location (~/Mail) were moved to ~/.mmh. The
20 environment variables to change these locations were renamed.
22 *) Many configure options were removed. (Sec. 2.1.4)
23 *) A bunch of recent changes in nmh were pulled into mmh.
24 *) The man page mmh-intro(7) was added.
28 *) Jon Steinhart's attachment system is made the default and is
29 combined smoothly with automatic MIMEification, as needed. The
30 `mime' command at the WhatNow prompt is therefore no longer needed
31 and thus removed. Use of Mime-Type-Query command (usually file(1))
32 to determine the MIME type of an attachment. No more writing of
33 mhbuild directives, although it is still possible to do so. (Sec.
35 *) The draft folder facility is always used. All support for a single
36 draft message is removed. The commands, especially comp(1), were
37 adjusted to this change. (Sec. 2.2.4)
38 *) A trash folder facility is added. Backup prefixes are no longer
40 *) By default, messages are always displayed serially in a single
41 pager session without pausing. Foreign charsets are transcoded
42 automatically (with iconv(1)). (Sec. 2.2.2)
43 *) Attachments are stored under their filename, instead of the message
44 number and MIME part number, by default. Tar files are no longer
45 extracted automatically. (Sec. 2.2.2)
46 *) scan(1) listings do no longer show body contents.
47 *) MMDF maildrop format support is removed. (Sec. 2.2.1) Support for
48 UUCP bang paths is gone, too.
49 *) There is no more support for automatic message/external-body
50 retrieval. The internal FTP client was dropped as well.
51 *) Removed the internal pager.
52 *) There is no more hardcopy terminal support. (Sec. 2.2.1)
56 *) The old show(1) was dropped and mhshow(1) was renamed to show(1).
58 *) Digital typography is added by including Neil Rickert's scripts:
59 mhsign(1) is invoked automatically by send(1) if the draft message
60 contains `Enc:' or `Sign:' header fields. Up to now, the user needs
61 to run mhpgp(1) manually, still. (Sec. 2.2.3)
62 *) conflict, rcvtty, viamail, msgchk, and msh were removed. (Sec. 2.1.2)
63 *) Replaced install-mh(1) with the shell script mmh(1).
64 *) slocal(1) lost its suppress duplicates feature and mmh thus lost the
66 *) packf(1) prints to stdout.
68 *) whom(1) is rewritten from scratch.
69 *) Many command line switches were removed. (Sec. 2.1.5)
70 *) anno(1)'s command line switches were structurally reworked. Check
71 the man page for details. (Sec. 2.3.2)
72 *) Replaced the command line option `-format foo' with `-form =foo'.
74 *) Path notations (with +, @, /, .) can now be used more interchangeable.
76 *) All tools read the profile now. (Sec. 2.3.3)
77 *) Renamed the -version switch to -Version.
81 *) The standard sequences `first', `prev', `cur', `next', `last',
82 `all', `new' were renamed to `f', `p', `c', `n', `l', `a', `b',
84 *) The unseen sequence and the sequence negation are set by default.
85 repl(1) quotes the original message by default and forw(1) uses
86 MIME encapsulation by default. (Sec. 2.2.5)
90 *) The indent style was changed -- sorry for that. (Sec. 2.3.1)
91 *) Standard library functions have replaced local replacements, when
92 possible. (Sec. 2.3.4)
93 *) The programs are more separated now. Instead of sharing source code,
94 the programs invoke each other. (Sec. 2.3.6)
95 *) Mmh comprises only about half as much code as nmh-1.3.
