|---|
| 2 | The following are the differences between nmh and MH-6.8.3. UCI has |
|---|
| 3 | since released MH-6.8.4. Most of the new features it adds have |
|---|
| 4 | also been added to nmh, but those differences are not listed here. |
|---|
| 5 | There are a few new features in MH-6.8.4 that are missing from nmh, |
|---|
| 6 | but they are primarily undocumented in MH-6.8.4 (and no one has |
|---|
| 7 | ever asked me for them). |
|---|
| 8 | |
|---|
| 9 | GENERAL |
|---|
| 10 | ------- |
|---|
| 11 | *) nmh has been converted to autoconf (configure) and should be |
|---|
| 12 | more portable and easier to install than MH. In particular, nmh |
|---|
| 13 | will now compile on Linux. |
|---|
| 14 | *) All of MH's Makefiles have been rewritten for nmh. You can now |
|---|
| 15 | use GNU make without any problems. Also, if your make supports |
|---|
| 16 | the VPATH variable (such as GNU make), you can now compile in a |
|---|
| 17 | different directory from the one containing the source code. |
|---|
| 18 | *) The source code for nmh has been substantially cleaned up. |
|---|
| 19 | It now requires an ANSI C compiler (gcc is fine) to compile. |
|---|
| 20 | *) A new option `-version' has been added to all the commands. |
|---|
| 21 | *) The POP server (popd) has been removed from the distribution. |
|---|
| 22 | But the client-side support for POP and KPOP is still present. |
|---|
| 23 | Also nmh doesn't currently support some of the alternate forms of |
|---|
| 24 | POP such as APOP or RPOP that are contained in MH (although they |
|---|
| 25 | could easily be resurrected, if necessary). |
|---|
| 26 | *) The support for MH-style bulletin boards has been removed |
|---|
| 27 | (NNTP makes this obsolete anyway). |
|---|
| 28 | *) Currently nmh doesn't support using shared libraries for libmh. |
|---|
| 29 | This may return in the future, but is not a high priority, since |
|---|
| 30 | the nmh commands are not that large, and disk space gets cheaper |
|---|
| 31 | every day. |
|---|
| 32 | *) Almost all of the commands in nmh have been modified to accept |
|---|
| 33 | an arbitrary number of command line arguments (most MH commands |
|---|
| 34 | will not accept more than 1000 arguments on the command line). |
|---|
| 35 | *) nmh should be more secure than MH. Hundreds of buffer overflow |
|---|
| 36 | problems have been fixed in the source code. Of course, I still |
|---|
| 37 | don't make any guarantees. |
|---|
| 38 | |
|---|
| 39 | DOCUMENTATION |
|---|
| 40 | ------------- |
|---|
| 41 | *) Many of the man pages have been cleaned up or clarified. |
|---|
| 42 | *) The mhook man page has been split into separate man pages for |
|---|
| 43 | rcvtty, rcvdist, and rcvpack. |
|---|
| 44 | *) Added new man page `mh-draft' which discusses the nmh draft |
|---|
| 45 | folder facility. |
|---|
| 46 | *) The various `procs' (rmmproc, moreproc, showmimeproc, etc...) |
|---|
| 47 | are now documented in the "mh-profile" man page. Many of these |
|---|
| 48 | were previously undocumented. |
|---|
| 49 | |
|---|
| 50 | FORMATTING |
|---|
| 51 | ---------- |
|---|
| 52 | *) Added a new formatting string escape %(decode) to decode and |
|---|
| 53 | display RFC-2047 encoded header fields. |
|---|
| 54 | |
|---|
| 55 | SEQUENCES |
|---|
| 56 | --------- |
|---|
| 57 | *) The is no longer a limitation on the length of lines in the file |
|---|
| 58 | containing your public sequences (.mh_sequences). That should be |
|---|
| 59 | the end of the error message ".mh_sequences is poorly formatted". |
|---|
| 60 | |
|---|
| 61 | ANNO |
|---|
| 62 | ---- |
|---|
| 63 | *) The switch -inplace is now on by default. |
|---|
| 64 | |
|---|
| 65 | CONFLICT |
|---|
| 66 | -------- |
|---|
| 67 | *) Conflict now works on systems that define more |
|---|
| 68 | than 100 groups. |
|---|
| 69 | |
|---|
| 70 | DIST |
|---|
| 71 | ---- |
|---|
| 72 | *) The switch -inplace is now on by default. |
|---|
| 73 | |
|---|
| 74 | FLIST |
|---|
| 75 | ----- |
|---|
| 76 | *) A new command `flist' has been added to nmh, that will list the |
|---|
| 77 | folders that contain messages in a given sequence (such as the |
|---|
| 78 | unseen sequence). This was a much needed command in the MH suite |
|---|
| 79 | of programs. |
|---|
| 80 | |
|---|
| 81 | FOLDER |
|---|
| 82 | ------ |
|---|
| 83 | *) `folder -all' now dynamically allocates space for folder names and can |
|---|
| 84 | handle more than 300 folders. |
|---|
| 85 | *) `folder' now uses the standard Unix trick of looking at the number of |
|---|
| 86 | links to a directory entry, in order to avoid doing a stat(2) call |
|---|
| 87 | on messages in folders with no subfolders. This greatly increases |
|---|
| 88 | the speed of `folder -all -recurse' on large mail setups. |
|---|
| 89 | *) The switches `-header' and `-total' are more orthogonal. The command |
|---|
| 90 | `folder -all -noheader -nototal' now does the right thing. |
|---|
| 91 | |
|---|
| 92 | FORW |
|---|
| 93 | ---- |
|---|
| 94 | *) The switch -inplace is now on by default. |
|---|
| 95 | *) Added switches `-dashstuffing' and `-nodashstuffing', to determine |
|---|
| 96 | whether forwarded messages are RFC934 quotes (dashstuffed). |
|---|
| 97 | (This corresponds to the undocumented switch "nodashmunging" |
|---|
| 98 | in MH). |
|---|
| 99 | |
|---|
| 100 | INC |
|---|
| 101 | --- |
|---|
| 102 | *) If compiled with RPATHS, a Delivery-Date header is now added to all |
|---|
| 103 | messages incorporated with `inc'. |
|---|
| 104 | *) Using the new format string escape %(decode), the scan lines for `inc' |
|---|
| 105 | will correctly decode RFC-2047 encoded headers. |
|---|
| 106 | |
|---|
| 107 | MARK |
|---|
| 108 | ---- |
|---|
| 109 | *) If neither of the switches -public/-nopublic are specified, then |
|---|
| 110 | existing sequences will retain their current public/private status, |
|---|
| 111 | instead of being changed to public. |
|---|
| 112 | *) The command "mark -list -sequence foo" will now indicate if the |
|---|
| 113 | sequence "foo" is a private sequence. |
|---|
| 114 | |
|---|
| 115 | MHBUILD |
|---|
| 116 | ------- |
|---|
| 117 | *) The functionality in `mhn' to create MIME messages, has been cleaned |
|---|
| 118 | up substantially, and moved to separate command `mhbuild'. |
|---|
| 119 | *) If given a file argument of "-", mhbuild will now accept the MIME |
|---|
| 120 | composition file on the standard input, and output the new MIME |
|---|
| 121 | message to the standard output. This makes it much easier to use |
|---|
| 122 | this functionality in shell scripts. |
|---|
| 123 | *) The switch -norfc934mode is now the default. |
|---|
| 124 | |
|---|
| 125 | MHL |
|---|
| 126 | --- |
|---|
| 127 | *) There is a new variable "decode" which instructs `mhl' to decode |
|---|
| 128 | a component as a RFC-2047 encoded header field. |
|---|
| 129 | |
|---|
| 130 | MHLIST |
|---|
| 131 | ------ |
|---|
| 132 | *) The functionality of `mhn -list' has been moved to the new |
|---|
| 133 | command `mhlist'. |
|---|
| 134 | |
|---|
| 135 | MHN |
|---|
| 136 | --- |
|---|
| 137 | *) mhn is now obsolete. It has been split into the commands mhbuild, |
|---|
| 138 | mhlist, mhshow, mhstore, and viamail. mhn still exists for |
|---|
| 139 | backward compatibility, but the new commands should be preferred. |
|---|
| 140 | *) Changed the profile entry automhnproc to automimeproc |
|---|
| 141 | (which has slightly different semantics). |
|---|
| 142 | |
|---|
| 143 | MHPATH |
|---|
| 144 | ------ |
|---|
| 145 | *) `mhpath all' will no longer abort if the folder has more than |
|---|
| 146 | 998 messages. |
|---|
| 147 | |
|---|
| 148 | MHSHOW |
|---|
| 149 | ------ |
|---|
| 150 | *) The functionality of `mhn -show' has been moved to the new |
|---|
| 151 | command `mhshow'. |
|---|
| 152 | *) mhshow now correctly treats unknown subtypes of text as |
|---|
| 153 | text/plain, as specified by RFC-2046. |
|---|
| 154 | *) mhshow now correctly treats unknown subtypes of multipart as |
|---|
| 155 | multipart/mixed, as specified by RFC-2046. |
|---|
| 156 | *) You can now override the default method by which mhshow handles |
|---|
| 157 | subtypes of multipart that are known internally (mixed, alternate, |
|---|
| 158 | etc...). Previously the behavior on these types could not be |
|---|
| 159 | changed. |
|---|
| 160 | |
|---|
| 161 | MHSTORE |
|---|
| 162 | ------- |
|---|
| 163 | *) The functionality of `mhn -store' has been moved to the new |
|---|
| 164 | command `mhstore'. |
|---|
| 165 | *) mhstore will now correctly identify a formatting string of "-" |
|---|
| 166 | and send the content to stdout. |
|---|
| 167 | |
|---|
| 168 | PACKF |
|---|
| 169 | ----- |
|---|
| 170 | *) When packing a folder, the default format is now `mbox' format, rather |
|---|
| 171 | than `mmdf' format. The options -mbox and -mmdf have been added to |
|---|
| 172 | `packf' so you can choose the desired format. |
|---|
| 173 | |
|---|
| 174 | PACKMBOX |
|---|
| 175 | -------- |
|---|
| 176 | *) The script packmbox has been removed from the nmh distribution, since |
|---|
| 177 | its functionality has been added to the command packf. |
|---|
| 178 | |
|---|
| 179 | PICK |
|---|
| 180 | ---- |
|---|
| 181 | *) If neither of the switches -public/-nopublic are specified, then |
|---|
| 182 | existing sequences will retain their current public/private status, |
|---|
| 183 | instead of being changed to public. |
|---|
| 184 | |
|---|
| 185 | RCVPACK |
|---|
| 186 | ------- |
|---|
| 187 | *) The default format for `rcvpack' is now `mbox' format, rather than |
|---|
| 188 | `mmdf' format. The options -mbox and -mmdf have been added to |
|---|
| 189 | `rcvpack' so you can choose the desired format. |
|---|
| 190 | *) Rcvpack no longer adds the field "Delivery-Date", as that is added |
|---|
| 191 | by `slocal'. |
|---|
| 192 | |
|---|
| 193 | RCVSTORE |
|---|
| 194 | -------- |
|---|
| 195 | *) Added new switches -unseen/-nounseen to control whether new messages |
|---|
| 196 | are added to the Unseen-Sequence. |
|---|
| 197 | |
|---|
| 198 | RCVTTY |
|---|
| 199 | ------ |
|---|
| 200 | *) The option `-width' has been added. |
|---|
| 201 | |
|---|
| 202 | REFILE |
|---|
| 203 | ------ |
|---|
| 204 | *) If an conflict occurs when using the `-preserve' switch, |
|---|
| 205 | then refile will search for and use the next available |
|---|
| 206 | message number above the one you wish to preserve, rather |
|---|
| 207 | than aborting with an error. |
|---|
| 208 | *) Added new options `-unlink' and `-nounlink' which specify |
|---|
| 209 | that that messages "removed" from the source folder should |
|---|
| 210 | just be unlinked, rather than moved to name with prefix. |
|---|
| 211 | |
|---|
| 212 | REPL |
|---|
| 213 | ---- |
|---|
| 214 | *) Added new options `-format' and `-noformat'. The switch `-format' |
|---|
| 215 | will filter the message to which you are replying with a standard |
|---|
| 216 | message filter "mhl.reply" which is included in the distribution. |
|---|
| 217 | The switch `-noformat' will negate `-format' and `-filter', so that |
|---|
| 218 | the message to which you are replying is not included in the draft. |
|---|
| 219 | *) Added new options `-group' and `-nogroup'. These switches direct |
|---|
| 220 | repl as to whether or not this is a group reply. A group reply uses |
|---|
| 221 | a different forms (components) file (default is replgroupcomps). |
|---|
| 222 | *) The standard forms files "replcomps" and "replgroupcomps" now have |
|---|
| 223 | support for the "Mail-Reply-To:" and "Mail-Followup-To:" header fields. |
|---|
| 224 | *) The switch -inplace is now on by default. |
|---|
| 225 | |
|---|
| 226 | RMM |
|---|
| 227 | --- |
|---|
| 228 | *) Added new options `-unlink' and `-nounlink' which specify |
|---|
| 229 | that that "removed" messages should just be unlinked, rather |
|---|
| 230 | than moved to name with prefix. |
|---|
| 231 | |
|---|
| 232 | SCAN |
|---|
| 233 | ---- |
|---|
| 234 | *) Using the new format string escape %(decode), the scan lines created |
|---|
| 235 | by `scan' will correctly decode RFC-2047 encoded headers. |
|---|
| 236 | |
|---|
| 237 | SHOW/NEXT/PREV |
|---|
| 238 | -------------- |
|---|
| 239 | *) Added new options `-checkmime' and `-nocheckmime' which allow you |
|---|
| 240 | to enable and disable the test for MIME messages. |
|---|
| 241 | *) The "mhnproc" profile entry has been changed to "showmimeproc". |
|---|
| 242 | *) Added `-showmimeproc' switch to specify the showmimeproc at the |
|---|
| 243 | command line. |
|---|
| 244 | *) The default "showproc" has been changed to `mhl'. |
|---|
| 245 | *) The default "showmimeproc" is now `mhshow'. |
|---|
| 246 | *) `show' is better at handling alternate character sets. It knows that |
|---|
| 247 | US-ASCII is a subset of any ISO-8859-X character set. |
|---|
| 248 | |
|---|
| 249 | SLOCAL |
|---|
| 250 | ------ |
|---|
| 251 | *) Added new action `folder' or `+' to slocal, which adds new message |
|---|
| 252 | to a nmh folder. Currently, this is handled by piping the new |
|---|
| 253 | message to rcvstore, although this may change in the future. |
|---|
| 254 | *) The action `mbox' now delivers to a file in mbox format. Previously |
|---|
| 255 | it delivered to a file in mmdf format. |
|---|
| 256 | *) Added new action `mmdf' to deliver to a file in mmdf format. |
|---|
| 257 | *) Added new options -[no]suppressdup to slocal to check for duplicate |
|---|
| 258 | messages. The code for suppression of duplicate messages (MH config |
|---|
| 259 | was MSGID) is now always built into slocal. |
|---|
| 260 | *) Improved the debugging of slocal ".maildelivery" files. It will now |
|---|
| 261 | warn when an entry in this file is skipped because there are not |
|---|
| 262 | enough fields. Also the debugging output of slocal has been cleaned up, |
|---|
| 263 | so that it is much easier to read. |
|---|
| 264 | *) Slocal now adds the Delivery-Date header to all delivered messages. |
|---|
| 265 | Previously it only added them to messages delivered to a file. |
|---|
| 266 | |
|---|
| 267 | VIAMAIL |
|---|
| 268 | ------- |
|---|
| 269 | *) The functionality of this new command, was formerly part of |
|---|
| 270 | `mhn' as the (undocumented) option `mhn -viamail'. |
|---|
| 271 | |
|---|
| 272 | WHATNOW |
|---|
| 273 | ------- |
|---|
| 274 | *) Added new action "mime" to whatnow, which causes whatnow to call |
|---|
| 275 | program specified by "buildmimeproc" profile entry, to process |
|---|
| 276 | MIME composition files (default is mhbuild). |
|---|
| 277 | *) Added new action "delete" to whatnow, which deletes draft file |
|---|
| 278 | and exits. |
|---|
