6 ** PGP 5.0i and GnuPG are now supported for PGP/MIME
8 You can select the various PGP or GnuPG commands by the user option
9 `pgp-version' or the command `mime-mc-setversion'. Note that Mailcrypt
10 3.5.3 or later is needed for PGP 5.0i or GnuPG. A user interface for
11 editing or viewing has never changed.
14 ** Requires FLIM 1.13 API
17 ** Don't expect raw-buffer
19 In FLIM 1.13 API, existence of a raw-buffer corresponding to each
20 entity is not guaranteed.
22 *** Now acting-method must not expect to run in raw-buffer
24 Function `mime-play-entity' was changed to permit to run in any buffer
25 (may be called in preview-buffer). So each acting-method is called in
28 *** Don't refer variable `mime-raw-buffer'
30 Preview-buffer's local variable `mime-raw-buffer' is deleted. So
33 *** Don't refer variable `mime-preview-buffer'
35 There are no guarantee about existence of a raw-buffer corresponding
36 to each entity, so don't refer buffer local variables of the
37 raw-buffer, e.g. `mime-preview-buffer'.
40 ** Function `mime-play-entity'
42 Function `mime-play-entity' was renamed from `mime-raw-play-entity'
43 and changed interface.
47 mime-play-entity (entity &optional situation ignored-method)
49 Please use `situation' if you would like to specify `mode' and
53 ** Text property `mime-view-entity-{header|body}'
55 Now mime-view put text property `mime-view-entity-header' and
56 `mime-view-entity-body' in header and body of each entity.
59 ** Behavior change about `mime-display-header-hook'
61 Function `mime-display-entity' runs `mime-display-header-hook' before
64 In addition, now it is cleared that current point means beginning of
65 header when `mime-display-entity' runs `mime-display-header-hook'.
66 Therefore header-presentation-method must not change current point.
69 ** New variable `mime-preview-move-scroll'
71 This variables decides how to scroll in the MIME-View-mode
72 when mime-preview-move-upper, mime-preview-move-previous,
73 mime-preview-move-next is called. Those are bound to `u', `p', `n',
77 * Changes in SEMI 1.12
79 There are no user-visible changes.
81 ** New function `eliminate-top-spaces'
86 * Changes in SEMI 1.11
88 ** New function `mime-edit-decode-message-in-buffer'
90 Add new function `mime-edit-decode-message-in-buffer'. Function
91 `mime-edit-decode-buffer' was abolished.
94 ** Requires FLIM 1.12 API
97 * Changes in SEMI 1.10
99 ** Abolish variable `mime-temp-directory'
101 FLIM 1.11 and SEMI 1.10 use variable `temporary-file-directory'
102 instead of `mime-temp-directory'. So environment variable
103 "MIME_TMP_DIR" and "TM_TMP_DIR" are not effective to specify temporary
104 directory of FLIM and SEMI.
107 ** Abolish function `mime-text-insert-decoded-body'
109 SEMI 1.10 uses function `mime-insert-text-content' of FLIM 1.11 API
110 instead of `mime-text-insert-decoded-body'.
112 Now `mime-view-caesar' does not run `mime-text-decode-hook'.
115 * Changes in SEMI 1.9
117 ** User option `mime-encoding-list'
119 SEMI 1.9 requires FLIM 1.10 API. In FLIM 1.10 API, variable
120 `mime-file-encoding-method-alist' was abolished. If you want to use
121 non-standard Content-Transfer-Encoding to insert a file into sending
122 message, please edit new user option `mime-encoding-list' instead of
123 `mime-file-encoding-method-alist'.
126 ** Constant `mime-user-interface-product'
128 Constant `mime-user-interface-version' was renamed to
129 `mime-user-interface-product'. Notice that data format is changed
132 FLIM 1.10 API provides following macros to access a slot of the new
135 mime-product-name (product)
137 mime-product-version (product)
139 mime-product-code-name (product)
141 Please use them to get elements of the constant
142 `mime-user-interface-product'.
145 * Changes in SEMI 1.8
147 ** Don't use "file" command to detect content of entity
149 Acting-method to detect content of entity was modified not to use
152 Variable `mime-file-content-type-alist' was abolished. Instead of
153 it, new variable `mime-magic-type-alist' is available to customize.
154 It is an alist of regexp about magic-number vs. corresponding
155 media-types. Each element looks like (REGEXP TYPE SUBTYPE). REGEXP
156 is a regular expression to match against the beginning of the content
157 of entity. TYPE is symbol to indicate primary type of media-type.
158 SUBTYPE is symbol to indicate subtype of media-type.
161 ** Abolish external X-Face viewer
164 ** Abolish obsolete utility for *-field-list and *-field-regexp
166 Abolish function `tm:set-fields', `tm:add-fields' and
170 ** Change MUA interface of automatic message/partial combining
172 Abolish variable `mime-view-partial-message-method-alist'.
174 Instead of it, `request-partial-message-method' in acting-situation
175 is available to specify MUA depended implementation.
177 Each element of `mime-view-partial-message-method-alist' were
178 required to display message at current summary line, and its return
179 value were ignored. On the other hand,
180 `request-partial-message-method' is required to return structure of
181 message at current summary line. Format of it is mime-entity.
186 MIME-Edit inserts User-Agent field instaed of X-Emacs field if
187 `mime-edit-insert-user-agent-field' is not nil. Contents of
188 User-Agent is specified by mime-edit-user-agent-value'.
190 X-Emacs field related features were abolished.
193 * Changes in SEMI 1.7
195 ** Header-presentation-method
197 Now MIME-View uses header-presentation-method instead of
200 - abolish variable `mime-view-content-header-filter-alist'
202 - abolish function `mime-view-cut-header'
204 - Rename `mime-view-content-header-filter-hook' to
205 `mime-display-header-hook'
208 ** Abolish `mime-view-ignored-field-regexp'
210 Now mime-view uses `mime-view-ignored-field-list' directly in
211 default header-presentation-method.
214 ** Abolish body filter support
216 Please use body-presentation-method.
221 - Rename `mime-view-following-method-alist' to
222 `mime-preview-following-method-alist'
224 - Rename `mime-method-to-combine-message/partial-pieces' to
225 `mime-combine-message/partial-pieces-automatically'
228 * Changes in SEMI 1.6
230 ** Abolish tm-compatible external method support
232 Abolish tm-compatible external method support. Please use mailcap
233 method instead of it.
236 ** Abolish `mime-edit-signing-type' and `mime-edit-encrypting-type'
238 C-c C-m C-s encloses as "pgp-signed" which means PGP/MIME signature.
240 C-c C-m C-e encloses as "pgp-encrypted" which means PGP/MIME
244 ** New method to detect content of entity
246 Now MIME-View can detect content of entity for
247 application/octet-stream in default setting.
249 It uses "file" command to detect. User can customize
250 `mime-file-content-type-alist' to specify media-type for output of
251 "file" command. It is an alist of "file" output patterns
252 vs. corresponding media-types. Each element looks like (REGEXP TYPE
253 SUBTYPE). REGEXP is pattern for "file" command output. TYPE is
254 symbol to indicate primary type of media-type. SUBTYPE is symbol to
255 indicate subtype of media-type.
258 ** New interface to display message
260 - Function `mime-view-buffer'
261 - Function `mime-view-display-message'
264 ** Change interface of internal playback method
266 Interface of internal playback method was changed to
270 It is as same as interface of body-presentation-method.
273 ** Change interface of `mime-view-entity-button-visible-p'
275 ** Change interface of `mime-view-insert-entity-button'
278 ** `mime-preview-original-major-mode'
280 Abolish variable `mime-preview-original-major-mode'.
282 Please use function `mime-preview-original-major-mode' instead of
286 ** mime-preview-over-to-{previous|next}-method-alist
288 `mime-preview-over-to-{previous|next}-method-alist' were renamed
289 from `mime-view-over-to-{previous|next}-method-alist'.
292 * Changes in SEMI 1.5
296 Add inline text/html preview feature using w3. If
297 `mime-setup-enable-inline-html' is not nil, semi-setup.el sets up it.
300 ** `pgp-elkins' -> `pgp-mime'
302 Rename `pgp-elkins' -> `pgp-mime'. Variable
303 `mime-edit-signing-type' and `mime-edit-encrypting-type' does not
307 ** type-subtype-score
309 Now MIME-View chooses one entity to display body in
310 multipart/alternative. In this mechanism,
311 `mime-view-type-subtype-score-alist' is used to specify priority of
314 Variable `mime-view-type-subtype-score-alist' is alist of
315 TYPE-SUBTYPE vs. SCORE. TYPE-SUBTYPE is cons pair (TYPE . SUBTYPE),
316 symbol TYPE or t. TYPE and SUBTYPE are symbol. `t' means default.
317 SCORE is integer. Larger number is larger priority.
322 Change text presentation mechanism. In anything older than SEMI
323 1.4, text presentation mechanism is based on filter model. However it
324 has design problem about conversion between byte representation and
325 text presentation. So SEMI was changed to use
326 body-presentation-method to display text entity. In this purpose, old
327 text decoding features were abolished and introduces news features
331 ** mime-raw-representation-type and mime-raw-representation-type-alist
333 Abolish `mime-text-decoder' and `mime-text-decoder-alist' because of
334 text presentation mechanism change (cf. previous section). Instead of
335 it, SEMI introduces variable about representation-type of
336 mime-raw-buffer. If it is `binary', mime-raw-buffer is as same as
337 network representation. If it is `cooked', mime-raw-buffer is
340 `mime-raw-representation-type-alist' is an alist of major-mode
341 vs. representation-type. Each element looks like
343 (SYMBOL . REPRESENTATION-TYPE).
345 SYMBOL is major-mode or t. t means default.
347 `mime-raw-representation-type' is a buffer local variable of
348 mime-raw-buffer. If it is non-nil, it overrides
349 `mime-raw-representation-type-alist'.
351 In addition, `mime-raw-buffer-coding-system-alist' was abolished.
352 Because representation-type has enough information.
355 * Changes in SEMI 1.4
359 mailcap was supported to set up 'mime-acting-condition.
361 tm-external-method scripts written by born shell were abolished.
364 ** mime-add-condition
366 New function to set up 'mime-preview-condition and/or
367 'mime-acting-condition.
370 ** signature setting in semi-setup.el
372 Abolish MUA depended signature setting.
374 Setting for mail-mode were moved to mail-mime-setup.el.
377 * Changes in SEMI 1.3
379 ** mime-acting-condition
381 Format of variable 'mime-acting-condition was changed from `atype'
382 to `condition tree'. Its format is as same as
383 'mime-preview-condition.
385 If there are two or more conditions are found when matching, menu
386 pops up to select method to run. Selected situation will be added to
387 example database. (cf. mime-acting-situation-examples-file)
391 *** mime-view-find-every-acting-situation
393 Find every available acting-situation if non-nil.
395 *** mime-acting-situation-examples-file
397 File name of example about acting-situation demonstrated by
401 * Changes in SEMI 1.2
407 'mime-view-plain-text-preview-hook was renamed to
408 'mime-preview-text/plain-hook.
412 Variable 'mime-view-childrens-header-showing-Content-Type-list was
413 abolished. Please use 'mime-preview-condition instead.
415 *** API about visible-predicates were abolished
417 Following functions were abolished:
419 mime-view-header-visible-p (entity message-info)
421 mime-view-body-visible-p (entity message-info)
423 mime-view-entity-separator-visible-p (entity message-info)
425 Please use 'mime-preview-condition instead.
427 Function 'mime-view-entity-button-visible-p is not abolished, but it
430 *** mime-preview-condition
432 Following are added as pre-defined keys:
434 'childrens-situation default preview-situation for children
435 'message-button to specify to display message-button
436 nil: default (invisible)
438 'invisible: invisible
439 'entity-button to specify to display entity-button
440 nil: default (visible)
442 'invisible: invisible
443 'header to specify to display header
444 nil: default (invisible)
446 'invisible: invisible
450 *** Interface for body-filter
452 'mime-view-filter-for-* was renamed to 'mime-preview-filter-for-*.
455 *** mime-text-decode-body
457 Function 'mime-decode-text-body was renamed to
458 'mime-text-decode-body and changed interface. New interface is
461 mime-text-decode-body (SITUATION)
463 SITUATION is preview-situation. Content-Transfer-Encoding and
464 MIME-charset are specified in field of it.
467 * Changes in SEMI 1.1
471 *** Setting variable about visible body
473 'mime-view-visible-media-type-list and
474 'mime-view-content-filter-alist were abolished. Please use
475 'mime-preview-condition instead.
477 Notice that 'mime-preview-condition is not list of
478 media-type/subtype string nor association-list. It uses new
479 data-structure `ctree' (condition-tree; it is introduced to replace
480 `atype'). Function 'ctree-set-calist-strictly and
481 'ctree-set-calist-with-default may be useful to modify it (`calist'
482 (condition-alist) is as same as `atype').
485 *** API about visible-predicates
487 Interface of visible-predicates for entity elements were changed.
488 New interfaces are following:
490 mime-view-entity-button-visible-p (entity message-info)
492 mime-view-header-visible-p (entity message-info)
494 mime-view-body-visible-p (entity message-info)
496 mime-view-entity-separator-visible-p (entity message-info)
501 *** entity representation
503 Structure 'mime-entity-info was renamed to 'mime-entity. So various
504 functions were renamed too.
507 *** Interface for entity-button generators
509 Interface of entity-button generators was changed. New interfaces
512 mime-view-insert-entity-button (entity message-info subject)
515 *** mime-preview-condition and preview-situation
517 Conditions about preview generation are unified to
518 'mime-preview-condition. Namely other variables, such as
519 'mime-view-visible-media-type-list, 'mime-view-content-filter-alist,
520 'mime-view-image-converter-alist were abolished.
522 Preview-situation is generated from entity information, running
523 environment and 'mime-preview-condition. These elements are checked
524 to match with each other. (it is similar to acting-situation)
526 Format of preview-situation is association-list. Following key is
530 'subtype media-subtype
531 'encoding content-transfer-encoding
532 'major-mode major-mode of MUA
533 <STRING> attribute of Content-Type field.
534 'body-presentation-method body-presentation-method
536 If 'body-presentation-method is 'with-filter, 'body-filter is used to
537 specify body-filter function. If 'body-presentation-method is
538 function, it is called to generate presentation of entity body.
540 Body-filter function 'mime-view-filter-for-image refers 'image-format.
542 Setting for message/partial button is specified by
543 'mime-preview-condition instead of hard-coding.
546 *** Interface for body-filter
548 Interface of body-filter was changed. New interfaces is following:
550 <body-filter> (situation)
552 Current pre-defined filters are following:
554 mime-view-filter-for-text/plain (situation)
555 mime-view-filter-for-text/richtext (situation)
556 mime-view-filter-for-text/enriched (situation)
557 mime-view-filter-for-image (situation) ; if available
559 'mime-view-filter-for-application/postscript was abolished.
562 *** Format of mime-acting-condition (acting-situation)
564 Format of `mime-acting-condition' were changed. `type' and
565 `subtype' are separated and changed to symbol.
570 - mime-view-buffer -> mime-preview-buffer
