92 | These chapters introduce another interface to MH that is accessible | |
93 | through the GNU Emacs editor, namely, @emph{mh-e}. mh-e is easy to use. | |
94 | I don't assume that you know GNU Emacs or even MH at this point, since I | |
95 | didn't know either of them when I discovered mh-e. However, mh-e was | |
96 | the tip of the iceberg, and I discovered more and more niceties about | |
97 | GNU Emacs and MH@. Now I'm fully hooked on both of them. | |
98 | ||
99 | @cindex history | |

8878f198 BW |
101 | The mh-e package is distributed with GNU Emacs, @footnote{Note that |
102 | mh-e is supported with MH 6 and @w{Emacs 18} through @w{Emacs 21}. | |
6bf7aab6 | 103 | Reportedly, large parts of it work with @w{MH 5} and also with |
8878f198 BW |
104 | Lucid/XEmacs and Epoch, but there are no guarantees. It is also |
105 | distributed with Lucid/XEmacs, as well as with MH itself.} so you | |
106 | shouldn't have to do anything special to use it. But it's important to | |
107 | note a brief history of mh-e. @w{Version 3} was prevalent through the | |
108 | @w{Emacs 18} and early @w{Emacs 19} years. Then @w{Version 4} came out | |
109 | (@w{Emacs 19.23}), which introduced several new and changed commands. | |
110 | Finally, @w{Version 5.0} was released, which fixed some bugs and | |
111 | incompatibilities, and was incorporated into @w{Emacs 19.29}. This is | |
112 | the version covered by this manual. @ref{Getting Started} will help | |
113 | you decide which version you have. | |
6bf7aab6 DL |
114 | |
115 | If you don't already use GNU Emacs but want to learn more, you can read | |
116 | an online tutorial by starting GNU Emacs and typing @kbd{C-h t} | |
117 | (@code{help-with-tutorial}). (This notation is described in | |
118 | @ref{Conventions}.) If you want to take the plunge, consult the | |
119 | @iftex | |

126 | ||
127 | If more information is needed, you can go to the Unix manual pages of | |
128 | the individual MH commands. When the name is not obvious, I'll guide | |
129 | you to a relevant MH manual page that describes the action more fully. | |

139 | @chapter Tour Through mh-e | |
140 | ||
141 | This chapter introduces some of the terms you'll need to know and then | |
142 | takes you on a tour of mh-e. @footnote{The keys mentioned in these | |
143 | chapters refer to the default key bindings. If you've changed the | |
144 | bindings, refer to the command summaries at the beginning of each major | |
145 | section in @ref{Using mh-e}, for a mapping between default key bindings | |
146 | and function names.} When you're done, you'll be able to send, read, | |
147 | and file mail, which is all that a lot of people ever do. But if you're | |
148 | the curious type, you'll read @ref{Using mh-e} to be able to use all | |
149 | the features of mh-e. If you're the adventurous type, you'll read | |
150 | @ref{Customizing mh-e} to make mh-e do what you want. I suggest you | |
151 | read this chapter first to get the big picture, and then you can read | |
152 | the other two as you wish. | |

172 | If you're an experienced Emacs user, you can skip the following | |
173 | conventions and definition of terms and go directly to @ref{Getting | |
174 | Started} below. The conventions are as follows: | |
175 | ||
176 | @table @kbd | |
177 | @item C-x | |
178 | Hold down the @key{CTRL} (Control) key and press the @kbd{x} key. | |
179 | @item M-x | |
180 | Hold down the @key{META} or @key{ALT} key and press the @kbd{x} key. | |
181 | ||
182 | Since some keyboards don't have a @key{META} key, you can generate | |
183 | @kbd{M-x}, for example, by pressing @key{ESC} (Escape), @emph{releasing | |
184 | it}, @footnote{This is emphasized because pressing ESC twice or holding | |
185 | it down a second too long so that it repeats gives you an error message.} | |
186 | and then pressing the @kbd{x} key. | |
187 | @item RET | |
188 | Press the @key{RETURN} or @key{ENTER} key. This is normally used to | |
189 | complete a command. | |
190 | @item SPC | |
191 | Press the space bar. | |
192 | @item TAB | |
193 | Press the @key{TAB} key. | |
194 | @item DEL | |
8878f198 BW |
195 | Press the @key{DELETE} key. |
196 | @item BS | |
197 | Press the @key{BACKSPACE} key. @footnote{If you are using Version 20 | |
198 | or earlier of Emacs, you will need to use the @key{DEL} key.} | |

202 | @cindex prefix argument | |
203 | ||
204 | A @dfn{prefix argument} allows you to pass an argument to any Emacs | |
205 | function. To pass an argument, type @kbd{C-u} before the Emacs command | |
206 | or keystroke. Numeric arguments can be passed as well. For example, to | |
207 | insert five f's, use @kbd{C-u 5 f}. There is a default of four when | |
208 | using @kbd{C-u}, and you can use multiple prefix arguments to provide | |
209 | arguments of powers of four. To continue our example, you could insert | |
210 | four f's with @kbd{C-u f}, 16 f's with @kbd{C-u C-u f}, 64 f's with | |
211 | @kbd{C-u C-u C-u f}, and so on. Numeric and valueless negative | |
212 | arguments can also be inserted with the @key{META} key. Examples | |
213 | include @kbd{M-5} to specify an argument of 5, or @kbd{M--} which | |
214 | specifies a negative argument with no particular value. | |

221 | The prefix @kbd{C-u} or @kbd{M-} is not necessary in mh-e's MH-Folder | |
222 | modes (@pxref{Reading Mail Tour}). In these modes, simply enter the | |
223 | numerical argument before entering the command. | |

231 | @cindex Emacs, region | |
232 | ||
233 | There are several other terms that are used in Emacs that you should | |
234 | know. The @dfn{point} is where the cursor currently is. You can save | |
235 | your current place in the file by setting a @dfn{mark}. This operation | |
236 | is useful in several ways. The mark can be later used when defining a | |
237 | @dfn{region}, which is the text between the point and mark. Many | |
238 | commands operate on regions, such as those for deleting text or filling | |
239 | paragraphs. A mark can be set with @kbd{C-@@} (or @kbd{C-SPC}). | |

245 | ||
246 | The @dfn{minibuffer} is the bottom line of the Emacs window, where all | |
247 | prompting and multiple-character input is directed. If you are prompted | |
248 | for information in the minibuffer, such as a filename, Emacs can help | |
249 | you complete your answer if you type @key{SPC} or @key{TAB}. A second | |
250 | @key{SPC} or @key{TAB} will list all possibilities at that point. The | |
251 | minibuffer is also where you enter Emacs function names after typing | |
252 | @kbd{M-x}. For example, in the first paragraph, I mentioned that you | |
253 | could obtain help with @kbd{C-h t} (@code{help-with-tutorial}). What | |
254 | this means is that you can get a tutorial by typing either @kbd{C-h t} | |
255 | or @kbd{M-x help-with-tutorial}. In the latter case, you are prompted | |
256 | for @samp{help-with-tutorial} in the minibuffer after typing @kbd{M-x}. | |

261 | @cindex Emacs, quitting | |
262 | ||
263 | @i{In case of trouble:} Emacs can be interrupted at any time with | |
264 | @kbd{C-g}. For example, if you've started a command that requests that | |
265 | you enter something in the minibuffer, but then you change your mind, | |
266 | type @kbd{C-g} and you'll be back where you started. If you want to | |
267 | exit Emacs entirely, use @kbd{C-x C-c}. | |
268 | ||
269 | @node Getting Started, Sending Mail Tour, Conventions, Tour Through mh-e | |
270 | @section Getting Started | |
271 | ||
272 | Because there are many old versions of mh-e out there, it is important to | |
273 | know which version you have. I'll be talking about @w{Version 5} which | |
274 | is similar to @w{Version 4} and vastly different from @w{Version 3}. | |
275 | ||
276 | First, enter @kbd{M-x load-library @key{RET} mh-e | |
277 | @key{RET}}. @footnote{You wouldn't ordinarily do this.} The message, | |
278 | @samp{Loading mh-e...done}, should be displayed in the minibuffer. If | |
279 | you get @samp{Cannot open load file: mh-e}, then your Emacs is very | |
280 | badly configured, or mh-e is missing. You may wish to have your system | |
281 | administrator install a new Emacs or at least the latest mh-e files. | |
282 | ||
283 | Having loaded mh-e successfully, enter @kbd{M-x mh-version @key{RET}}. | |
284 | The version of mh-e should be displayed. Hopefully it says that you're | |
285 | running @w{Version @value{VERSION}} which is the latest version as of | |
286 | this printing. If instead Emacs beeps and says @samp{[No match]}, then | |
287 | you're running an old version of mh-e. | |
288 | ||
289 | If these tests reveal a non-existent or old version of mh-e, please | |
290 | consider obtaining a new version. You can have your system | |
291 | administrator upgrade the system-wide version, or you can install your | |
292 | own personal version. It's really quite easy; instructions for getting | |
8878f198 | 293 | and installing mh-e are in @ref{Getting mh-e}. |
6bf7aab6 DL |
294 | |
295 | @cindex @code{install-mh} | |
296 | @cindex MH commands, @code{install-mh} | |
297 | ||
298 | Also, older versions of mh-e assumed that you had already set up your MH | |
299 | environment. Newer versions set up a new MH environment for you by | |
300 | running @code{install-mh} and notifying you of this fact with the | |
301 | message in a temporary buffer: | |
302 | ||
303 | @example | |
304 | I'm going to create the standard MH path for you. | |
305 | @end example | |
306 | ||
307 | Therefore, if you've never run MH before and you're using an old version | |
308 | of mh-e, you need to run @code{install-mh} from the shell before you | |
309 | continue the tour. If you don't, you'll be greeted with the error | |
310 | message: @samp{Can't find MH profile}. | |
311 | ||
312 | @cindex @file{.emacs} | |
313 | @cindex files, @file{.emacs} | |
314 | ||
315 | If, during the tour described in this chapter, you see a message like: | |
316 | @samp{Searching for program: no such file or directory, | |
317 | /usr/local/bin/mhpath}, it means that the MH programs and files are kept | |
318 | in a nonstandard directory. In this case, simply add the following to | |
319 | @file{~/.emacs} and restart @code{emacs}. | |

329 | @end group | |
330 | @end example | |
331 | ||
332 | @cindex ~ | |
333 | ||
334 | The @samp{~} notation used by @file{~/.emacs} above represents your home | |
335 | directory. This is used by the @code{bash} and @code{csh} shells. If | |
336 | your shell does not support this feature, you could use the environment | |
337 | variable @samp{$HOME} (such as @file{$HOME/.emacs}) or the absolute path | |
338 | (as in @file{/home/wohler/.emacs}) instead. | |
339 | ||
340 | At this point, you should see something like the screen in the | |

350 | read and process. Enter @kbd{M-x mh-smail} to invoke the mh-e program | |
351 | to send messages. You will be prompted in the minibuffer by @samp{To:}. | |
352 | Enter your login name. The next prompt is @samp{cc:}. Hit @key{RET} to | |

469 | The first thing we want to do is reply to the message that we sent | |
470 | ourselves. Ensure that the cursor is still on the same line as your | |
471 | test message and type @kbd{r}. You are prompted in the minibuffer with | |
472 | @samp{Reply to whom:}. Here mh-e is asking whether you'd like to reply | |
473 | to the original sender only, to the sender and primary recipients, or to | |
474 | the sender and all recipients. If you simply hit @key{RET}, you'll | |
475 | reply only to the sender. Hit @key{RET} now. | |

520 | With your cursor in the MH-Folder buffer and positioned on the message | |
521 | you sent to yourself, type @kbd{o} to output (@code{refile} in MH | |
522 | parlance) that message to a folder. Enter @kbd{test} at the | |
523 | @samp{Destination:} prompt and type @kbd{y} (or @key{SPC}) when mh-e | |
524 | asks to create the folder @samp{+test}. Note that a @samp{^} (caret) | |
525 | appears next to the message number, which means that the message has | |

535 | use @kbd{n} or @kbd{p} to move the cursor to the new message, and read | |
536 | it with @key{RET}. Let's delete this message by typing @kbd{d}. Note | |
537 | that a @samp{D} appears next to the message number. This means that the | |
538 | message is marked for deletion but is not yet deleted. To perform the | |

737 | A digest is a message that contains other messages. Special mh-e | |

754 | Another handy command is @kbd{M-b} (@code{mh-burst-digest}). This | |
755 | command uses the MH command @code{burst} to break out each message in | |
756 | the digest into its own message. Using this command, you can quickly | |
757 | delete unwanted messages, like this: Once the digest is split up, toggle | |
758 | out of MH-Folder Show mode with @kbd{t} (@pxref{Moving Around}) so that | |
759 | the scan lines fill the screen and messages aren't displayed. Then use | |
760 | @kbd{d} (@pxref{Deleting}) to quickly delete messages that you don't | |
761 | want to read (based on the @samp{Subject:} header field). You can also | |
762 | burst the digest to reply directly to the people who posted the messages | |
763 | in the digest. One problem you may encounter is that the @samp{From:} | |
764 | header fields are preceded with a @samp{>} so that your reply can't | |
765 | create the @samp{To:} field correctly. In this case, you must correct | |
766 | the @samp{To:} field yourself. This is described later in @ref{Editing | |

838 | mh-smail} directly, or from the command line like this: | |
839 | ||
840 | @cindex starting from command line | |
841 | ||
842 | @example | |
843 | % @kbd{emacs -f mh-smail} | |
844 | @end example | |
845 | ||
846 | From within mh-e's MH-Folder mode, other methods of sending mail | |
847 | are available as well: | |
848 | ||
849 | @table @kbd | |
850 | @item m | |
851 | Compose a message (@code{mh-send}). | |
852 | ||

861 | ||

873 | @findex @code{mh-send} | |
874 | ||
875 | From within a MH-Folder buffer, you can simply use the command @kbd{m} | |
876 | (@code{mh-send}). However you invoke @code{mh-send}, you are prompted | |
877 | for the @samp{To:}, @samp{cc:}, and @samp{Subject:} header fields. Once | |
878 | you've specified the recipients and subject, your message appears in an | |
879 | Emacs buffer whose mode is MH-Letter (see the Figure in @ref{Sending | |
880 | Mail} to see what the buffer looks like). MH-Letter mode allows you to | |
881 | edit your message, to check the validity of the recipients, to insert | |
882 | other messages into your message, and to send the message. We'll go | |
883 | more into depth about editing a @dfn{draft} @footnote{I highly recommend | |
884 | that you use a @dfn{draft folder} so that you can edit several drafts in | |
885 | parallel. To do so, create a folder (e.g., @file{+drafts}), and add a | |
886 | profile component called @samp{Draft-Folder:} which contains | |
887 | @file{+drafts} (see @code{mh-profile}(5)).} (a message you're composing) | |
888 | in just a moment. | |
889 | ||
890 | @findex @code{mh-smail} | |
891 | @findex @code{mh-smail-other-window} | |
892 | ||
893 | @code{mh-smail} always creates a two-window layout with the current | |
894 | buffer on top and the draft on the bottom. If you would rather preserve | |
895 | the window layout, use @kbd{M-x mh-smail-other-window}. | |

1124 | ||
1125 | It is often useful to insert a snippet of text from a letter that | |
1126 | someone mailed to provide some context for your reply. The command | |
1127 | @kbd{C-c C-y} (@code{mh-yank-cur-msg}) does this by yanking a portion of | |
1128 | text from the message to which you're replying and inserting @samp{> } | |
1129 | before each line. | |
1130 | ||
1131 | @cindex mark | |

1134 | @cindex Emacs, point | |
1135 | @cindex region | |
1136 | @cindex Emacs, region | |
1137 | ||
1138 | You can control how much text is included when you run this command. If | |
1139 | you run this command right away, without entering the buffer containing | |
1140 | the message to you, this command will yank the entire message, as is, | |
1141 | into your reply. @footnote{If you'd rather have the header cleaned up, | |
1142 | use @kbd{C-u r} instead of @kbd{r} when replying (see @ref{Replying}).} | |
1143 | If you enter the buffer containing the message sent to you and move the | |
1144 | cursor to a certain point and return to your reply and run @kbd{C-c | |
1145 | C-y}, then the text yanked will range from that point to the end of the | |
1146 | message. Finally, the most common action you'll perform is to enter the | |
1147 | message sent to you, move the cursor to the beginning of a paragraph or | |
1148 | phrase, set the @dfn{mark} with @kbd{C-SPC} or @kbd{C-@@}, and move the | |
1149 | cursor to the end of the paragraph or phrase. The cursor position is | |
1150 | called the @dfn{point}, and the space between the mark and point is | |
1151 | called the @dfn{region}. Having done that, @kbd{C-c C-y} will insert | |
1152 | the region you selected. | |

1161 | This command prompts you for the folder and message number and inserts | |
1162 | the message, indented by @samp{> }. Certain undesirable header fields | |
1163 | are removed before insertion. If given a prefix argument (like @kbd{C-u | |
1164 | C-c C-i}), the header is left intact, the message is not indented, and | |
1165 | @samp{> } is not inserted before each line. | |

1173 | Because the header is part of the message, you can edit the header | |
1174 | fields as you wish. However, several convenience functions exist to | |
1175 | help you create and edit them. For example, the command @kbd{C-c C-f | |
1176 | C-t} (@code{mh-to-field}; alternatively, @kbd{C-c C-f t}) moves the | |
1177 | cursor to the @samp{To:} header field, creating it if necessary. The | |
1178 | functions to move to the @samp{cc:}, @samp{Subject:}, @samp{From:}, | |
1179 | @samp{Bcc:}, and @samp{Dcc:} header fields are similar. | |
1180 | ||
1181 | @findex @code{mh-to-fcc} | |

1183 | One function behaves differently from the others, namely, @kbd{C-c C-f | |
1184 | C-f} (@code{mh-to-fcc}; alternatively, @kbd{C-c C-f f}). This function | |
1185 | will prompt you for the folder name in which to file a copy of the draft. | |

1662 | filename. If the file already exists, the message is appended to it. | |
1663 | You can also write the message to the file without the header by | |
1664 | specifying a prefix argument (such as @kbd{C-u C-o /tmp/foobar RET}). | |

1766 | Edit this template by entering your search criteria in an appropriate | |
1767 | header field that is already there, or create a new field yourself. If | |
1768 | the string you're looking for could be anywhere in a message, then place | |
1769 | the string underneath the row of dashes. The @kbd{M-s} command uses the | |
1770 | MH command @code{pick} to do the real work, so read @code{pick}(1) to | |
1771 | find out more about how to enter the criteria. | |
1772 | ||
1773 | There are no semantics associated with the search criteria---they are | |
1774 | simply treated as strings. Case is ignored when all lowercase is used, | |
1775 | and regular expressions (a la @code{ed}) are available. It is all right | |
1776 | to specify several search criteria. What happens then is that a logical | |
1777 | @emph{and} of the various fields is performed. If you prefer a logical | |
1778 | @emph{or} operation, run @kbd{M-s} multiple times. | |

1853 | For the whole scoop on MH sequences, refer to @code{mh-sequence}(5). As | |
1854 | you've read, several of the mh-e commands can operate on a sequence, | |
1855 | which is a shorthand for a range or group of messages. For example, you | |
1856 | might want to forward several messages to a friend or colleague. Here's | |

1889 | To place a message in a sequence, use @kbd{%} (@code{mh-put-msg-in-seq}) | |
1890 | to do it manually, or use the MH command @code{pick} or the mh-e version | |
1891 | of @code{pick} (@ref{Searching}) which create a sequence automatically. | |
1892 | Give @kbd{%} a prefix argument and you can add all the messages in one | |
1893 | sequence to another sequence (for example, @kbd{C-u % SourceSequence | |
1894 | RET}). | |

1901 | Once you've placed some messages in a sequence, you may wish to narrow | |
1902 | the field of view to just those messages in the sequence you've created. | |
1903 | To do this, use @kbd{C-x n} (@code{mh-narrow-to-seq}). You are prompted | |
1904 | for the name of the sequence. What this does is show only those | |
1905 | messages that are in the selected sequence in the MH-Folder buffer. In | |
1906 | addition, it limits further mh-e searches to just those messages. When | |
1907 | you want to widen the view to all your messages again, use @kbd{C-x w} | |
1908 | (@code{mh-widen}). | |
1909 | ||
1910 | @findex @code{mh-msg-is-in-seq} | |

1915 | @c Doesn't work: | |
1916 | @c use a prefix argument to query a | |
8878f198 | 1917 | @c message other than the current one (as in @kbd{C-u ? 42 RET}). XXX |
6bf7aab6 DL |
1918 | Or, you can list all sequences in a selected folder (default is current |
1919 | folder) with @kbd{M-q} (@code{mh-list-sequences}). | |

1921 | @findex @code{mh-delete-msg-from-seq} | |
1922 | @findex @code{mh-delete-seq} | |
1923 | ||
1924 | If you want to remove a message from a sequence, use @kbd{M-%} | |
1925 | (@code{mh-delete-msg-from-seq}), and if you want to delete an entire | |
1926 | sequence, use @kbd{M-#} (@code{mh-delete-seq}). In the latter case you | |
1927 | are prompted for the sequence to delete. Note that this deletes only | |
1928 | the sequence, not the messages in the sequence. If you want to delete | |
1929 | the messages, use @kbd{C-u d} (see @ref{Deleting} above). | |

1936 | Two sequences are maintained internally by mh-e and pushed out to MH | |

1938 | sequence specified by your @samp{Unseen-Sequence:} profile entry and | |
1939 | @i{cur}. However, you can also just update MH's state with the command | |
1940 | @kbd{M-x mh-update-sequences}. See @ref{Customizing Viewing} for an | |
1941 | example of how this command might be used. | |
1942 | ||
1943 | With the exceptions of @kbd{C-x n} and @kbd{C-x w}, the underlying MH | |

1958 | ||
1959 | Until now, we've talked about the mh-e commands as they work ``out of the | |
177c0ea7 | 1960 | box.'' Of course, it is also possible to reconfigure mh-e |
8878f198 BW |
1961 | to fit the needs of even the most demanding user. |
1962 | The following sections describe all of the | |
6bf7aab6 DL |
1963 | customization variables, show the defaults, and make recommendations for |
1964 | customization. The outline of this chapter is identical to that of | |
1965 | @ref{Using mh-e}, to make it easier to find the variables you'd need to | |
1966 | modify to affect a particular command. | |
1967 | ||
1968 | However, when customizing your mail environment, first try to change | |
1969 | what you want in MH, and only change mh-e if changing MH is not | |
1970 | possible. That way you will get the same behavior inside and outside | |
1971 | GNU Emacs. Note that mh-e does not provide hooks for customizations | |
1972 | that can be done in MH; this omission is intentional. | |

1977 | Many string or integer variables are easy enough to modify using Emacs | |
1978 | Lisp. Any such modifications should be placed in a file called | |
1979 | @file{.emacs} in your home directory (that is, @file{~/.emacs}). For | |
1980 | example, to modify the variable that controls printing, you could add: | |
1981 | ||
1982 | @vindex @code{mh-lpr-command-format}, example | |
1983 | ||
1984 | @lisp | |
1985 | (setq mh-lpr-command-format "nenscript -G -r -2 -i'%s'") | |
1986 | @end lisp | |

1990 | @cindex setting variables | |
1991 | @cindex Emacs, setting variables | |
1992 | ||
1993 | Variables can also hold Boolean values. In Emacs Lisp, the Boolean | |
1994 | values are @code{nil}, which means false, and @code{t}, which means true. | |
1995 | Usually, variables are turned off by setting their value to @code{nil}, as | |
1996 | in | |
1997 | ||
1998 | @vindex @code{mh-bury-show-buffer}, example | |
1999 | ||

2001 | (setq mh-bury-show-buffer nil) | |
2002 | @end lisp | |
2003 | ||
2004 | which keeps the MH-Show buffer at the top of the buffer stack. | |
2005 | To turn a variable on, you use | |
2006 | ||
2007 | @lisp | |
2008 | (setq mh-bury-show-buffer t) | |
2009 | @end lisp | |
2010 | ||
2011 | which places the MH-Show buffer at the bottom of the buffer | |
2012 | stack. However, the text says to turn on a variable by setting it to a | |
2013 | @emph{non-@code{nil}} value, because sometimes values other than @code{t} are | |
2014 | meaningful (for example, see @code{mhl-formfile}, described in | |
2015 | @ref{Customizing Viewing}). Other variables, such as hooks, involve a | |
2016 | little more Emacs Lisp programming expertise. | |
2017 | ||
2018 | You can also ``preview'' the effects of changing variables before | |
2019 | committing the changes to @file{~/.emacs}. Variables can be changed in | |

2194 | common places and in the user's @samp{PATH} environment variable, but if | |
2195 | it cannot find the directories, or finds the wrong ones, you should set | |
2196 | these variables. The name of the directory should be placed in double | |

2205 | disable confirmation for unrecoverable commands such as @kbd{M-k} | |
2206 | (@code{mh-kill-folder}) and @kbd{M-u} (@code{mh-undo-folder}). Here's | |

2219 | The variable @code{mh-summary-height} controls the number of scan lines | |
2220 | displayed in the MH-Folder window, including the mode line. The | |
2221 | default value of 4 means that 3 scan lines are displayed. Here's how | |
2222 | you set numerical values: | |
2223 | ||
2224 | @lisp | |

2232 | Normally the buffer for displaying messages is buried at the bottom at | |
2233 | the buffer stack. You may wish to disable this feature by setting | |
2234 | @code{mh-bury-show-buffer} to @code{nil}. One advantage of not burying the | |
2235 | show buffer is that one can delete the show buffer more easily in an | |
2236 | electric buffer list because of its proximity to its associated | |

2292 | Several variables control what displayed messages look like. Normally | |
2293 | messages are delivered with a handful of uninteresting header fields. | |
2294 | You can make them go away by setting @code{mh-clean-message-header} to a | |
2295 | non-@code{nil} value. The header can then be cleaned up in two ways. By | |
2296 | default, the header fields in @code{mh-invisible-headers} are removed. | |
2297 | On the other hand, you could set @code{mh-visible-headers} to the fields | |
2298 | that you would like to see. If this variable is set, | |
2299 | @code{mh-invisible-headers} is ignored. I suggest that you not set | |
2300 | @code{mh-visible-headers} since if you use this variable, you might miss | |
2301 | a lot of header fields that you'd rather not miss. As an example of how | |
2302 | to set a string variable, @code{mh-visible-headers} can be set to show a | |
2303 | minimum set of header fields (see (@ref{Regexps, , Syntax of Regular | |
2304 | Expressions, emacs, The GNU Emacs Manual}, for a description of the | |
2305 | special characters in this string): | |

2315 | Normally mh-e takes care of displaying messages itself (rather than | |
2316 | calling an MH program to do the work). If you'd rather have @code{mhl} | |
2317 | display the message (within mh-e), set the variable @code{mhl-formfile} | |
2318 | to a non-@code{nil} value. You can set this variable either to @code{t} | |
2319 | to use the default format file or to a filename if you have your own | |
2320 | format file (@code{mhl}(1) tells you how to write one). When writing | |
2321 | your own format file, use a nonzero value for @code{overflowoffset} to | |
2322 | ensure the header is RFC 822 compliant and parsable by mh-e. | |
2323 | @code{mhl} is always used for printing and forwarding; in this case, the | |
2324 | value of @code{mhl-formfile} is consulted if it is a filename. | |
2325 | ||

2328 | Two hooks can be used to control how messages are displayed. The first | |
2329 | hook, @code{mh-show-mode-hook}, is called early on in the process of | |
2330 | displaying of messages. It is used to perform some actions on the | |
2331 | contents of messages, such as highlighting the header fields. If you're | |
2332 | running Emacs 19 under the X Window System, the following example will | |
2333 | highlight the @samp{From:} and @samp{Subject:} header fields. This is a | |
2334 | very nice feature indeed. | |

2357 | The second hook, @code{mh-show-hook}, is the last thing called after | |
2358 | messages are displayed. It's used to affect the behavior of mh-e in | |
2359 | general or when @code{mh-show-mode-hook} is too early. For example, if | |
2360 | you wanted to keep mh-e in sync with MH, you could use | |
2361 | @code{mh-show-hook} as follows: | |
2362 | ||
2363 | @vindex @code{mh-show-hook}, example | |

2373 | The function @code{mh-update-sequences} is documented in @ref{Finishing | |
2374 | Up}. For those who like to modify their mode lines, use | |
2375 | @code{mh-show-buffer-mode-line-buffer-id} to modify the mode line in the | |
2376 | MH-Show buffers. Place the two escape strings @samp{%s} and @samp{%d}, | |
2377 | which will display the folder name and the message number, respectively, | |
2378 | somewhere in the string in that order. The default value of | |
2379 | @samp{"@{show-%s@} %d"} yields a mode line of | |
2380 | ||
2381 | @example | |

2462 | if it isn't @file{components}. This is the name of the file that | |
2463 | contains the form for composing messages. If it does not contain an | |
2464 | absolute pathname, mh-e searches for the file first in your MH directory | |
2465 | and then in the system MH library directory (such as | |
2466 | @file{/usr/local/lib/mh}). Replies, on the other hand, are built using | |

2932 | hook @code{mh-inc-folder-hook}, which is called after new mail is | |
2933 | incorporated by the @kbd{i} (@code{mh-inc-folder}) command. A good use | |

2964 | The hook @code{mh-delete-msg-hook} is called after you mark a message | |
2965 | for deletion. For example, the current maintainer of mh-e used this | |

2974 | ||
2975 | By default, operations on folders work only one level at a time. Set | |
2976 | @code{mh-recursive-folders} to non-@code{nil} to operate on all folders. | |
2977 | This mostly means that you'll be able to see all your folders when you | |
2978 | press @key{TAB} when prompted for a folder name. The variable | |
2979 | @code{mh-auto-folder-collect} is normally turned on to generate a list | |
2980 | of folder names in the background as soon as mh-e is loaded. Otherwise, | |
2981 | the list is generated when you need a folder name the first time (as | |
2982 | with @kbd{o} (@code{mh-refile-msg})). If you have a lot of folders and | |
2983 | you have @code{mh-recursive-folders} set, this could take a while, which | |
2984 | is why it's nice to do the folder collection in the background. | |

2991 | ||
2992 | The function @code{mh-default-folder-for-message-function} is used by | |
2993 | @kbd{o} (@code{mh-refile-msg}) and @kbd{C-c C-f C-f} (@code{mh-to-fcc}) | |
2994 | to generate a default folder. The generated folder name should be a | |
2995 | string with a @samp{+} before it. For each of my correspondents, I use the | |
2996 | same name for both an alias and a folder. So, I wrote a function that | |
2997 | takes the address in the @samp{From:} header field, finds it in my alias | |
2998 | file, and returns the alias, which is used as a default folder name. | |
2999 | This is the most complicated example given here, and it demonstrates | |
3000 | several features of Emacs Lisp programming. You should be able to drop | |
3001 | this into @file{~/.emacs}, however. If you use this to store messages | |
3002 | in a subfolder of your Mail directory, you can modify the line that | |
3003 | starts @samp{(format +%s...} and insert your subfolder after the folder | |
3004 | symbol @samp{+}. | |
3005 | @c Note for me: if I insert a new version, don't forget to remove the | |
3006 | @c "a/" from the folder name. | |

3284 | The string | |
3285 | @code{mh-partial-folder-mode-line-annotation} is used to annotate the | |
3286 | mode line when only a portion of the folder is shown. For example, this | |

3407 | mh-e was originally written by Brian Reid in 1983 and has changed |
3408 | hands several times since then. Jim Larus wanted to do something | |
3409 | similar for GNU Emacs, and ended up completely rewriting it that same | |
3410 | year. In 1989, Stephen Gildea picked it up and added many improvements. | |
3411 | Bill Wohler then took over in 2000 and moved its development to | |

3424 | ||
3425 | One day in 1983 I got the flu and had to stay home from work for three | |
3426 | days with nothing to do. I used that time to write MHE@. The | |
3427 | fundamental idea behind MHE was that it was a ``puppeteer'' driving the MH | |
3428 | programs underneath it. MH had a model that the editor was supposed to | |
3429 | run as a subprocess of the mailer, which seemed to me at the time to be | |
3430 | the tail wagging the dog. So I turned it around and made the editor | |
3431 | drive the MH programs. I made sure that the UCI people (who were | |
3432 | maintaining MH at the time) took in my changes and made them stick. | |
3433 | ||
3434 | Today, I still use my own version of MHE because I don't at all like the | |
3435 | way that GNU mh-e works and I've never gotten to be good enough at | |
3436 | hacking Emacs Lisp to make GNU mh-e do what I want. The Gosling-emacs | |
3437 | version of MHE and the GNU Emacs version of mh-e have almost nothing in | |
3438 | common except similar names. They work differently, have different | |
3439 | conceptual models, and have different key bindings. @footnote{After | |
3440 | reading this article, I questioned Brian about his version of MHE, and | |
3441 | received some great ideas for improving mh-e such as a dired-like method | |
3442 | of selecting folders; and removing the prompting when sending mail, | |
3443 | filling in the blanks in the draft buffer instead. I passed them on to | |
3444 | Stephen Gildea, the current maintainer, and he was excited about the | |
3445 | ideas as well. Perhaps one day, mh-e will again resemble MHE, although | |
3446 | none of these ideas are manifest in Version 5.0.} | |

3453 | @cindex Larus, Jim | |
3454 | ||
3455 | Brian Reid, while at CMU or shortly after going to Stanford wrote a mail | |
3456 | reading program called MHE for Gosling Emacs. It had much the same | |
3457 | structure as mh-e (i.e., invoked MH programs), though it was simpler and | |
3458 | the commands were slightly different. Unfortunately, I no longer have a | |
3459 | copy so the differences are lost in the mists of time. | |
3460 | ||
3461 | In '82-83, I was working at BBN and wrote a lot of mlisp code in Gosling | |
3462 | Emacs to make it look more like Tennex Emacs. One of the packages that | |
3463 | I picked up and improved was Reid's mail system. In '83, I went back to | |
3464 | Berkeley. About that time, Stallman's first version of GNU Emacs came | |
3465 | out and people started to move to it from Gosling Emacs (as I recall, | |
3466 | the transition took a year or two). I decided to port Reid's MHE and | |
3467 | used the mlisp to Emacs Lisp translator that came with GNU Emacs. It | |
3468 | did a lousy job and the resulting code didn't work, so I bit the bullet | |
3469 | and rewrote the code by hand (it was a lot smaller and simpler then, so | |
3470 | it took only a day or two). | |
3471 | ||
3472 | Soon after that, mh-e became part of the standard Emacs distribution and | |
3473 | suggestions kept dribbling in for improvements. mh-e soon reached | |
3474 | sufficient functionality to keep me happy, but I kept on improving it | |
3475 | because I was a graduate student with plenty of time on my hands and it | |
3476 | was more fun than my dissertation. In retrospect, the one thing that I | |
3477 | regret is not writing any documentation, which seriously limited the use | |
3478 | and appeal of the package. | |

3481 | ||
3482 | In '89, I came to Wisconsin as a professor and decided not to work on | |
3483 | mh-e. It was stable, except for minor bugs, and had enough | |
3484 | functionality, so I let it be for a few years. Stephen Gildea of BBN | |
3485 | began to pester me about the bugs, but I ignored them. In 1990, he went | |
3486 | off to the X Consortium, said good bye, and said that he would now be | |
3487 | using @code{xmh}. A few months later, he came back and said that he | |
3488 | couldn't stand @code{xmh} and could I put a few more bug fixes into | |
3489 | mh-e. At that point, I had no interest in fixing mh-e, so I gave the | |
3490 | responsibility of maintenance to him and he has done a fine job since | |
3491 | then. | |

3500 | In 1987 I went to work for Bolt Beranek and Newman, as Jim had before | |
3501 | me. In my previous job, I had been using RMAIL, but as my folders tend | |
3502 | to run large, I was frustrated with the speed of RMAIL@. However, I | |
3503 | stuck with it because I wanted the GNU Emacs interface. I am very | |
3504 | familiar and comfortable with the Emacs interface (with just a few | |
3505 | modifications of my own) and dislike having to use applications with | |
3506 | embedded editors; they never live up to Emacs. | |
3507 | ||
3508 | MH is the mail reader of choice at BBN, so I converted to it. Since I | |
3509 | didn't want to give up using an Emacs interface, I started using mh-e. | |
3510 | As is my wont, I started hacking on it almost immediately. I first used | |
3511 | version 3.4m. One of the first features I added was to treat the folder | |
3512 | buffer as a file-visiting buffer: you could lock it, save it, and be | |
3513 | warned of unsaved changes when killing it. I also worked to bring its | |
3514 | functionality a little closer to RMAIL@. Jim Larus was very cooperative | |
3515 | about merging in my changes, and my efforts first appeared in version | |
3516 | 3.6, distributed with Emacs 18.52 in 1988. Next I decided mh-e was too | |
3517 | slow and optimized it a lot. Version, 3.7, distributed with Emacs 18.56 | |
3518 | in 1990, was noticeably faster. | |
3519 | ||
3520 | When I moved to the X Consortium I became the first person there to not | |
3521 | use xmh. (There is now one other engineer there using mh-e.) About | |
3522 | this point I took over maintenance of mh-e from Jim and was finally able | |
3523 | to add some features Jim hadn't accepted, such as the backward searching | |
3524 | undo. My first release was 3.8 (Emacs 18.58) in 1992. | |
3525 | ||
3526 | Now, in 1994, we see a flurry of releases, with both 4.0 and 5.0. | |
3527 | Version 4.0 added many new features, including background folder | |
3528 | collection and support for composing @sc{mime} messages. (Reading | |
3529 | @sc{mime} messages remains to be done, alas.) While writing this book, | |
3530 | Bill Wohler gave mh-e its closest examination ever, uncovering bugs and | |
3531 | inconsistencies that required a new major version to fix, and so version | |
3532 | 5 was released. | |

3550 | ||
3551 | The licenses for most software are designed to take away your | |

3553 | License is intended to guarantee your freedom to share and change free | |
3554 | software---to make sure the software is free for all its users. This | |
3555 | General Public License applies to most of the Free Software | |
3556 | Foundation's software and to any other program whose authors commit to | |
3557 | using it. (Some other Free Software Foundation software is covered by | |
3558 | the GNU Library General Public License instead.) You can apply it to | |
3559 | your programs, too. | |
3560 | ||
3561 | When we speak of free software, we are referring to freedom, not | |
3562 | price. Our General Public Licenses are designed to make sure that you | |
3563 | have the freedom to distribute copies of free software (and charge for | |
3564 | this service if you wish), that you receive source code or can get it | |
3565 | if you want it, that you can change the software or use pieces of it | |
3566 | in new free programs; and that you know you can do these things. | |
3567 | ||
3568 | To protect your rights, we need to make restrictions that forbid | |
3569 | anyone to deny you these rights or to ask you to surrender the rights. | |
3570 | These restrictions translate to certain responsibilities for you if you | |
3571 | distribute copies of the software, or if you modify it. | |
3572 | ||
3573 | For example, if you distribute copies of such a program, whether | |
3574 | gratis or for a fee, you must give the recipients all the rights that | |
3575 | you have. You must make sure that they, too, receive or can get the | |
3576 | source code. And you must show them these terms so they know their | |
3577 | rights. | |
3578 | ||
3579 | We protect your rights with two steps: (1) copyright the software, and | |
3580 | (2) offer you this license which gives you legal permission to copy, | |
3581 | distribute and/or modify the software. | |
3582 | ||
3583 | Also, for each author's protection and ours, we want to make certain | |
3584 | that everyone understands that there is no warranty for this free | |
3585 | software. If the software is modified by someone else and passed on, we | |
3586 | want its recipients to know that what they have is not the original, so | |
3587 | that any problems introduced by others will not reflect on the original | |
3588 | authors' reputations. | |
3589 | ||
3590 | Finally, any free program is threatened constantly by software | |
3591 | patents. We wish to avoid the danger that redistributors of a free | |
3592 | program will individually obtain patent licenses, in effect making the | |
3593 | program proprietary. To prevent this, we have made it clear that any | |
3594 | patent must be licensed for everyone's free use or not licensed at all. | |
3595 | ||

3669 | and can be reasonably considered independent and separate works in | |
3670 | themselves, then this License, and its terms, do not apply to those | |
3671 | sections when you distribute them as separate works. But when you | |
3672 | distribute the same sections as part of a whole which is a work based | |
3673 | on the Program, the distribution of the whole must be on the terms of | |
3674 | this License, whose permissions for other licensees extend to the | |
3675 | entire whole, and thus to each and every part regardless of who wrote it. | |
3676 | ||
3677 | Thus, it is not the intent of this section to claim rights or contest | |
3678 | your rights to work written entirely by you; rather, the intent is to | |
3679 | exercise the right to control the distribution of derivative or | |
3680 | collective works based on the Program. | |
3681 | ||
3682 | In addition, mere aggregation of another work not based on the Program | |
3683 | with the Program (or with a work based on the Program) on a volume of | |
3684 | a storage or distribution medium does not bring the other work under | |
3685 | the scope of this License. | |
3686 | ||
3687 | @item | |
3688 | You may copy and distribute the Program (or a work based on it, | |
3689 | under Section 2) in object code or executable form under the terms of | |
3690 | Sections 1 and 2 above provided that you also do one of the following: | |
3691 | ||
3692 | @enumerate a | |
3693 | @item | |
3694 | Accompany it with the complete corresponding machine-readable | |
3695 | source code, which must be distributed under the terms of Sections | |
3696 | 1 and 2 above on a medium customarily used for software interchange; or, | |
3697 | ||
3698 | @item | |
3699 | Accompany it with a written offer, valid for at least three | |
3700 | years, to give any third party, for a charge no more than your | |
3701 | cost of physically performing source distribution, a complete | |
3702 | machine-readable copy of the corresponding source code, to be | |
3703 | distributed under the terms of Sections 1 and 2 above on a medium | |
3704 | customarily used for software interchange; or, | |
3705 | ||
3706 | @item | |
3707 | Accompany it with the information you received as to the offer | |
3708 | to distribute corresponding source code. (This alternative is | |
3709 | allowed only for noncommercial distribution and only if you | |
3710 | received the program in object code or executable form with such | |
3711 | an offer, in accord with Subsection b above.) | |
3712 | @end enumerate | |
3713 | ||
3714 | The source code for a work means the preferred form of the work for | |
3715 | making modifications to it. For an executable work, complete source | |
3716 | code means all the source code for all modules it contains, plus any | |
3717 | associated interface definition files, plus the scripts used to | |
3718 | control compilation and installation of the executable. However, as a | |
3719 | special exception, the source code distributed need not include | |
3720 | anything that is normally distributed (in either source or binary | |
3721 | form) with the major components (compiler, kernel, and so on) of the | |
3722 | operating system on which the executable runs, unless that component | |
3723 | itself accompanies the executable. | |
3724 | ||
3725 | If distribution of executable or object code is made by offering | |
3726 | access to copy from a designated place, then offering equivalent | |
3727 | access to copy the source code from the same place counts as | |
3728 | distribution of the source code, even though third parties are not | |
3729 | compelled to copy the source along with the object code. | |
3730 | ||
3731 | @item | |
3732 | You may not copy, modify, sublicense, or distribute the Program | |
3733 | except as expressly provided under this License. Any attempt | |
3734 | otherwise to copy, modify, sublicense or distribute the Program is | |
3735 | void, and will automatically terminate your rights under this License. | |
3736 | However, parties who have received copies, or rights, from you under | |
3737 | this License will not have their licenses terminated so long as such | |
3738 | parties remain in full compliance. | |
3739 | ||
3740 | @item | |
3741 | You are not required to accept this License, since you have not | |
3742 | signed it. However, nothing else grants you permission to modify or | |
3743 | distribute the Program or its derivative works. These actions are | |
3744 | prohibited by law if you do not accept this License. Therefore, by | |
3745 | modifying or distributing the Program (or any work based on the | |
3746 | Program), you indicate your acceptance of this License to do so, and | |
3747 | all its terms and conditions for copying, distributing or modifying | |
3748 | the Program or works based on it. | |
3749 | ||
3750 | @item | |
3751 | Each time you redistribute the Program (or any work based on the | |
3752 | Program), the recipient automatically receives a license from the | |
3753 | original licensor to copy, distribute or modify the Program subject to | |
3754 | these terms and conditions. You may not impose any further | |
3755 | restrictions on the recipients' exercise of the rights granted herein. | |
3756 | You are not responsible for enforcing compliance by third parties to | |
3757 | this License. | |
3758 | ||
3759 | @item | |
3760 | If, as a consequence of a court judgment or allegation of patent | |
3761 | infringement or for any other reason (not limited to patent issues), | |
3762 | conditions are imposed on you (whether by court order, agreement or | |
3763 | otherwise) that contradict the conditions of this License, they do not | |
3764 | excuse you from the conditions of this License. If you cannot | |
3765 | distribute so as to satisfy simultaneously your obligations under this | |
3766 | License and any other pertinent obligations, then as a consequence you | |
3767 | may not distribute the Program at all. For example, if a patent | |
3768 | license would not permit royalty-free redistribution of the Program by | |
3769 | all those who receive copies directly or indirectly through you, then | |
3770 | the only way you could satisfy both it and this License would be to | |
3771 | refrain entirely from distribution of the Program. | |
3772 | ||
3773 | If any portion of this section is held invalid or unenforceable under | |
3774 | any particular circumstance, the balance of the section is intended to | |
3775 | apply and the section as a whole is intended to apply in other | |
3776 | circumstances. | |
3777 | ||
3778 | It is not the purpose of this section to induce you to infringe any | |
3779 | patents or other property right claims or to contest validity of any | |
3780 | such claims; this section has the sole purpose of protecting the | |
3781 | integrity of the free software distribution system, which is | |
3782 | implemented by public license practices. Many people have made | |
3783 | generous contributions to the wide range of software distributed | |
3784 | through that system in reliance on consistent application of that | |
3785 | system; it is up to the author/donor to decide if he or she is willing | |
3786 | to distribute software through any other system and a licensee cannot | |
3787 | impose that choice. | |
3788 | ||
3789 | This section is intended to make thoroughly clear what is believed to | |
3790 | be a consequence of the rest of this License. | |
3791 | ||
3792 | @item | |
3793 | If the distribution and/or use of the Program is restricted in | |
3794 | certain countries either by patents or by copyrighted interfaces, the | |
3795 | original copyright holder who places the Program under this License | |
3796 | may add an explicit geographical distribution limitation excluding | |
3797 | those countries, so that distribution is permitted only in or among | |
3798 | countries not thus excluded. In such case, this License incorporates | |
3799 | the limitation as if written in the body of this License. | |
3800 | ||
3801 | @item | |
3802 | The Free Software Foundation may publish revised and/or new versions | |
3803 | of the General Public License from time to time. Such new versions will | |
3804 | be similar in spirit to the present version, but may differ in detail to | |
3805 | address new problems or concerns. | |
3806 | ||
3807 | Each version is given a distinguishing version number. If the Program | |
3808 | specifies a version number of this License which applies to it and ``any | |
df9d7630 | 3809 | later version,'' you have the option of following the terms and conditions |
6bf7aab6 DL |
3810 | either of that version or of any later version published by the Free |
3811 | Software Foundation. If the Program does not specify a version number of | |
3812 | this License, you may choose any version ever published by the Free Software | |
3813 | Foundation. | |
3814 | ||
3815 | @item | |
3816 | If you wish to incorporate parts of the Program into other free | |
3817 | programs whose distribution conditions are different, write to the author | |
3818 | to ask for permission. For software which is copyrighted by the Free | |
3819 | Software Foundation, write to the Free Software Foundation; we sometimes | |
3820 | make exceptions for this. Our decision will be guided by the two goals | |
3821 | of preserving the free status of all derivatives of our free software and | |
3822 | of promoting the sharing and reuse of software generally. | |

3862 | @appendixsec How to Apply These Terms to Your New Programs | |
3863 | ||
3864 | If you develop a new program, and you want it to be of the greatest | |
3865 | possible use to the public, the best way to achieve this is to make it | |
3866 | free software which everyone can redistribute and change under these terms. | |
3867 | ||
3868 | To do so, attach the following notices to the program. It is safest | |
3869 | to attach them to the start of each source file to most effectively | |
3870 | convey the exclusion of warranty; and each file should have at least | |
3871 | the ``copyright'' line and a pointer to where the full notice is found. | |
