1 User-visible changes to mh-e in version 5.0 from 4.1.
|
|
|
2
|
|
|
3 Note: This being a major release, there are many internal changes.
|
|
|
4 This document lists only changes to the external interfaces of mh-e.
|
|
|
5
|
|
|
6 When upgrading, you must either explicitly reload the new versions of
|
|
|
7 all mh-e files that are already loaded or restart your Emacs.
|
|
|
8
|
|
|
9 mh-e 5.0.1 contains minor changes from mh-e 5.0 to integrate it with
|
|
|
10 Emacs 19.29.
|
|
|
11
|
|
|
12 mh-e 5.0.2 contains additional minor changes to integrate it with
|
|
|
13 reporter.el (requires reporter.el version 3.1c or later) and Emacs
|
|
|
14 19.30. The mh-goto-msg function is much faster, which also speeds up
|
|
|
15 several other operations.

17 Major Changes and New Features in mh-e
|
|
|
18 ======================================
|
|
|
19
|
|
|
20 The emphasis for this release has been on consistency and
|
|
|
21 documentation. Many documentation strings were enhanced.
|
|
|
22 Documentation strings were changed to comments for internal functions
|
|
|
23 and variables.
|
|
|
24
|
|
|
25 There is now proper documentation in the form of a 75-page users
|
|
|
26 manual. The Texinfo source is mh-e.texi; the formatted Info document
|
|
|
27 is mh-e.info.
|
|
|
28
|
|
|
29 There is a new command `mh-update-sequences', which updates MH's
|
|
|
30 idea of what messages are in the Unseen sequence and what is the current
|
|
|
31 folder and message. `mh-quit' calls it. While `mh-execute-commands'
|
|
|
32 has always done this updating as a side effect, the new function is
|
|
|
33 faster.
|
|
|
34
|
|
|
35 The MH profile entry "Inbox:" is supported.
|
|
|
36
|
|
|
37 If the show-buffer is modified, the user is queried before mh-e
|
|
|
38 reuses the buffer to show a different message. This buffer is also
|
|
|
39 auto-saved and backed up correctly.
|
|
|
40
|
|
|
41 `mh-store-buffer' is significantly more robust. It now handles
|
|
|
42 messages created by a wide variety of packaging software. The status
|
|
|
43 message for `uudecode' includes the name of the file created. An error
|
|
|
44 is signaled if the subprocess exits with a non-zero status.
|
|
|
45
|
|
|
46 `mh-search-folder' behaves predictably, adding messages found to the
|
|
|
47 `search' sequence. It correctly handles the case of no messages found.
|
|
|
48
|
|
|
49 `mh-burst-digest' (`M-b') now only rescans the part of the folder
|
|
|
50 affected by the burst. It is now much faster in a large folder.
|
|
|
51
|
|
|
52 New mh-e Hooks and Customization Variables
|
|
|
53 ==========================================
|
|
|
54
|
|
|
55 `mh-default-folder-for-message-function': new name for the old
|
|
|
56 `mh-msg-folder-hook', which wasn't a hook. The old name was confusing,
|
|
|
57 leading people to think they could use `add-hook' with it, when
|
|
|
58 actually `setq' is the correct way.
|
|
|
59
|
|
|
60 `mh-sortm-args': When this variable is used has changed. Now
|
|
|
61 `mh-sortm-args' is passed if there IS a prefix argument to
|
|
|
62 `mh-sort-folder'. The assumption is that for arguments you normally
|
|
|
63 want, you would specify them in an MH profile entry.
|
|
|
64
|
|
|
65 `mh-mhn-args': new hook, a list of additional arguments to pass to
|
|
|
66 the `mhn' program if `mh-edit-mhn' is given a prefix argument.
|
|
|
67
|
|
|
68 `mh-edit-mhn-hook': new hook called by `mh-edit-mhn', the function
|
|
|
69 that formats MIME messages.
|
|
|
70
|
|
|
71 `mh-folder-list-change-hook': new hook, called whenever the cached
|
|
|
72 list of folders, `mh-folder-list', is changed.
|
|
|
73
|
|
|
74 `mh-find-path-hook': new hook, called when entering mh-e.
|
|
|
75
|
|
|
76 `mh-repl-formfile': new variable, used to change the format file
|
|
|
77 used by `mh-reply' from the default of "replcomps".
|
|
|
78
|
|
|
79 New variables to customize the scan format and notating:
|
|
|
80 `mh-note-deleted', `mh-note-refiled', `mh-note-seq', `mh-note-cur',
|
|
|
81 `mh-note-copied', `mh-note-printed'.
|
|
|
82
|
|
|
83 Key Binding Changes in mh-e
|
|
|
84 ===========================
|
|
|
85
|
|
|
86 `RET' runs `mh-show' for consistency with the Finder and Info. The
|
|
|
87 old binding `.' still works, but `RET' is now the standard binding.
|
|
|
88
|
|
|
89 `M-<' now runs `mh-first-msg' for consistency with `M->', which runs
|
|
|
90 `mh-last-msg'.
|
|
|
91
|
|
|
92 `C-c C-f C-d' in MH-Letter mode moves to a Dcc: header field.
|
|
|
93
|
|
|
94 `C-c C-f C-r' in MH-Letter mode moves to a From: header field.
|
|
|
95
|
|
|
96 `g' is now the standard binding for `mh-goto-msg'. The old binding
|
|
|
97 `j' still works.
|
|
|
98
|
|
|
99 Other Improvements and Changes to mh-e
|
|
|
100 ======================================
|
|
|
101
|
|
|
102 `mh-lpr-command-format' no longer passes the "-p" argument to `lpr'
|
|
|
103 by default. The mail header typically has the date anyway.
|
|
|
104
|
|
|
105 When prompting for a sequence name, if no sequences have been used
|
|
|
106 yet, mh-e will offer the first sequence the current message is in.
|
|
|
107
|
|
|
108 The patterns of more mailers are recognized by
|
|
|
109 `mh-extract-rejected-mail'.
|
|
|
110
|
|
|
111 `mh-insert-prefix-string' no longer wraps the call to the
|
|
|
112 `mail-citation-hook' function in a `save-excursion' so the hook writer
|
|
|
113 can choose whether to leave point at the beginning or the end of the
|
|
|
114 yanked text.
|
|
|
115
|
|
|
116 `mh-write-msg-to-file': The prompt now refers to "message" or
|
|
|
117 "message body" depending on which will be written. (This is controlled
|
|
|
118 by a prefix argument.) The file defaults to the last-used file instead
|
|
|
119 of supplying only the directory name.
|
|
|
120
|
|
|
121 mh-e uses message ranges when running MH commands. Thus "rmm 1 2 3
|
|
|
122 4 6" is now "rmm 1-4 6". This change makes it less likely to overflow
|
|
|
123 system argument list limits, and it might be faster, too.
|
|
|
124
|
|
|
125 Bug Fixes to mh-e
|
|
|
126 =================
|
|
|
127
|
|
|
128 mh-e's idea of the unseen sequence now stays in sync with MH's
|
|
|
129 better.
|
|
|
130
|
|
|
131 Functions that are supposed to find fields in the message header no
|
|
|
132 longer look in the message body.
|
|
|
133
|
|
|
134 mh-e would sometimes fail to remove the "%" from a scan line when the
|
|
|
135 message was removed from a sequence if the message was also in the
|
|
|
136 Previous sequence.
|
|
|
137
|
|
|
138 The variable `mh-inc-prog' is now correctly used in all places.
|
|
|
139
|
|
|
140 `mh-pipe-msg' runs the process in the correct directory.
|
|
|
141
|
|
|
142 A partially scanned folder will no longer lose the "/select"
|
|
|
143 annotation when you execute marked deletes and refiles with `x'.
|
|
|
144
