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 `pgg-default-scheme' or `pgg-scheme'. The former is for encrypting and
10 signing, the latter could be bound for controlling which command is
11 used to process the incoming PGP armors. Note that Mailcrypt is not
12 needed anymore. A user interface for editing or viewing has never
13 changed. Note also that `pgp-function' and `pgp-functions-alist' are
14 abolished in this version.
16 ** Requires FLIM 1.13 API
19 ** Don't expect raw-buffer
21 In FLIM 1.13 API, existence of a raw-buffer corresponding to each
22 entity is not guaranteed.
24 *** Now acting-method must not expect to run in raw-buffer
26 Function `mime-play-entity' was changed to permit to run in any buffer
27 (may be called in preview-buffer). So each acting-method is called in
30 *** Don't refer variable `mime-raw-buffer'
32 Preview-buffer's local variable `mime-raw-buffer' is deleted. So
35 *** Don't refer variable `mime-preview-buffer'
37 There are no guarantee about existence of a raw-buffer corresponding
38 to each entity, so don't refer buffer local variables of the
39 raw-buffer, e.g. `mime-preview-buffer'.
42 ** Function `mime-play-entity'
44 Function `mime-play-entity' was renamed from `mime-raw-play-entity'
45 and changed interface.
49 mime-play-entity (entity &optional situation ignored-method)
51 Please use `situation' if you would like to specify `mode' and
55 ** Text property `mime-view-entity-{header|body}'
57 Now mime-view put text property `mime-view-entity-header' and
58 `mime-view-entity-body' in header and body of each entity.
61 ** Behavior change about `mime-display-header-hook'
63 Function `mime-display-entity' runs `mime-display-header-hook' before
66 In addition, now it is cleared that current point means beginning of
67 header when `mime-display-entity' runs `mime-display-header-hook'.
68 Therefore header-presentation-method must not change current point.
71 ** New variable `mime-preview-move-scroll'
73 This variables decides how to scroll in the MIME-View-mode
74 when mime-preview-move-upper, mime-preview-move-previous,
75 mime-preview-move-next is called. Those are bound to `u', `p', `n',
79 * Changes in SEMI 1.12
81 There are no user-visible changes.
83 ** New function `eliminate-top-spaces'
88 * Changes in SEMI 1.11
90 ** New function `mime-edit-decode-message-in-buffer'
92 Add new function `mime-edit-decode-message-in-buffer'. Function
93 `mime-edit-decode-buffer' was abolished.
96 ** Requires FLIM 1.12 API
99 * Changes in SEMI 1.10
101 ** Abolish variable `mime-temp-directory'
103 FLIM 1.11 and SEMI 1.10 use variable `temporary-file-directory'
104 instead of `mime-temp-directory'. So environment variable
105 "MIME_TMP_DIR" and "TM_TMP_DIR" are not effective to specify temporary
106 directory of FLIM and SEMI.
109 ** Abolish function `mime-text-insert-decoded-body'
111 SEMI 1.10 uses function `mime-insert-text-content' of FLIM 1.11 API
112 instead of `mime-text-insert-decoded-body'.
114 Now `mime-view-caesar' does not run `mime-text-decode-hook'.
117 * Changes in SEMI 1.9
119 ** User option `mime-encoding-list'
121 SEMI 1.9 requires FLIM 1.10 API. In FLIM 1.10 API, variable
122 `mime-file-encoding-method-alist' was abolished. If you want to use
123 non-standard Content-Transfer-Encoding to insert a file into sending
124 message, please edit new user option `mime-encoding-list' instead of
125 `mime-file-encoding-method-alist'.
128 ** Constant `mime-user-interface-product'
130 Constant `mime-user-interface-version' was renamed to
131 `mime-user-interface-product'. Notice that data format is changed
134 FLIM 1.10 API provides following macros to access a slot of the new
137 mime-product-name (product)
139 mime-product-version (product)
141 mime-product-code-name (product)
143 Please use them to get elements of the constant
144 `mime-user-interface-product'.
147 * Changes in SEMI 1.8
149 ** Don't use "file" command to detect content of entity
151 Acting-method to detect content of entity was modified not to use
154 Variable `mime-file-content-type-alist' was abolished. Instead of
155 it, new variable `mime-magic-type-alist' is available to customize.
156 It is an alist of regexp about magic-number vs. corresponding
157 media-types. Each element looks like (REGEXP TYPE SUBTYPE). REGEXP
158 is a regular expression to match against the beginning of the content
159 of entity. TYPE is symbol to indicate primary type of media-type.
160 SUBTYPE is symbol to indicate subtype of media-type.
163 ** Abolish external X-Face viewer
166 ** Abolish obsolete utility for *-field-list and *-field-regexp
168 Abolish function `tm:set-fields', `tm:add-fields' and
172 ** Change MUA interface of automatic message/partial combining
174 Abolish variable `mime-view-partial-message-method-alist'.
176 Instead of it, `request-partial-message-method' in acting-situation
177 is available to specify MUA depended implementation.
179 Each element of `mime-view-partial-message-method-alist' were
180 required to display message at current summary line, and its return
181 value were ignored. On the other hand,
182 `request-partial-message-method' is required to return structure of
183 message at current summary line. Format of it is mime-entity.
188 MIME-Edit inserts User-Agent field instaed of X-Emacs field if
189 `mime-edit-insert-user-agent-field' is not nil. Contents of
190 User-Agent is specified by mime-edit-user-agent-value'.
192 X-Emacs field related features were abolished.
195 * Changes in SEMI 1.7
197 ** Header-presentation-method
199 Now MIME-View uses header-presentation-method instead of
202 - abolish variable `mime-view-content-header-filter-alist'
204 - abolish function `mime-view-cut-header'
206 - Rename `mime-view-content-header-filter-hook' to
207 `mime-display-header-hook'
210 ** Abolish `mime-view-ignored-field-regexp'
212 Now mime-view uses `mime-view-ignored-field-list' directly in
213 default header-presentation-method.
216 ** Abolish body filter support
218 Please use body-presentation-method.
223 - Rename `mime-view-following-method-alist' to
224 `mime-preview-following-method-alist'
226 - Rename `mime-method-to-combine-message/partial-pieces' to
227 `mime-combine-message/partial-pieces-automatically'
230 * Changes in SEMI 1.6
232 ** Abolish tm-compatible external method support
234 Abolish tm-compatible external method support. Please use mailcap
235 method instead of it.
238 ** Abolish `mime-edit-signing-type' and `mime-edit-encrypting-type'
240 C-c C-m C-s encloses as "pgp-signed" which means PGP/MIME signature.
242 C-c C-m C-e encloses as "pgp-encrypted" which means PGP/MIME
246 ** New method to detect content of entity
248 Now MIME-View can detect content of entity for
249 application/octet-stream in default setting.
251 It uses "file" command to detect. User can customize
252 `mime-file-content-type-alist' to specify media-type for output of
253 "file" command. It is an alist of "file" output patterns
254 vs. corresponding media-types. Each element looks like (REGEXP TYPE
255 SUBTYPE). REGEXP is pattern for "file" command output. TYPE is
256 symbol to indicate primary type of media-type. SUBTYPE is symbol to
257 indicate subtype of media-type.
260 ** New interface to display message
262 - Function `mime-view-buffer'
263 - Function `mime-view-display-message'
266 ** Change interface of internal playback method
268 Interface of internal playback method was changed to
272 It is as same as interface of body-presentation-method.
275 ** Change interface of `mime-view-entity-button-visible-p'
277 ** Change interface of `mime-view-insert-entity-button'
280 ** `mime-preview-original-major-mode'
282 Abolish variable `mime-preview-original-major-mode'.
284 Please use function `mime-preview-original-major-mode' instead of
288 ** mime-preview-over-to-{previous|next}-method-alist
290 `mime-preview-over-to-{previous|next}-method-alist' were renamed
291 from `mime-view-over-to-{previous|next}-method-alist'.
294 * Changes in SEMI 1.5
298 Add inline text/html preview feature using w3. If
299 `mime-setup-enable-inline-html' is not nil, semi-setup.el sets up it.
302 ** `pgp-elkins' -> `pgp-mime'
304 Rename `pgp-elkins' -> `pgp-mime'. Variable
305 `mime-edit-signing-type' and `mime-edit-encrypting-type' does not
309 ** type-subtype-score
311 Now MIME-View chooses one entity to display body in
312 multipart/alternative. In this mechanism,
313 `mime-view-type-subtype-score-alist' is used to specify priority of
316 Variable `mime-view-type-subtype-score-alist' is alist of
317 TYPE-SUBTYPE vs. SCORE. TYPE-SUBTYPE is cons pair (TYPE . SUBTYPE),
318 symbol TYPE or t. TYPE and SUBTYPE are symbol. `t' means default.
319 SCORE is integer. Larger number is larger priority.
324 Change text presentation mechanism. In anything older than SEMI
325 1.4, text presentation mechanism is based on filter model. However it
326 has design problem about conversion between byte representation and
327 text presentation. So SEMI was changed to use
328 body-presentation-method to display text entity. In this purpose, old
329 text decoding features were abolished and introduces news features
333 ** mime-raw-representation-type and mime-raw-representation-type-alist
335 Abolish `mime-text-decoder' and `mime-text-decoder-alist' because of
336 text presentation mechanism change (cf. previous section). Instead of
337 it, SEMI introduces variable about representation-type of
338 mime-raw-buffer. If it is `binary', mime-raw-buffer is as same as
339 network representation. If it is `cooked', mime-raw-buffer is
342 `mime-raw-representation-type-alist' is an alist of major-mode
343 vs. representation-type. Each element looks like
345 (SYMBOL . REPRESENTATION-TYPE).
347 SYMBOL is major-mode or t. t means default.
349 `mime-raw-representation-type' is a buffer local variable of
350 mime-raw-buffer. If it is non-nil, it overrides
351 `mime-raw-representation-type-alist'.
353 In addition, `mime-raw-buffer-coding-system-alist' was abolished.
354 Because representation-type has enough information.
357 * Changes in SEMI 1.4
361 mailcap was supported to set up 'mime-acting-condition.
363 tm-external-method scripts written by born shell were abolished.
366 ** mime-add-condition
368 New function to set up 'mime-preview-condition and/or
369 'mime-acting-condition.
372 ** signature setting in semi-setup.el
374 Abolish MUA depended signature setting.
376 Setting for mail-mode were moved to mail-mime-setup.el.
379 * Changes in SEMI 1.3
381 ** mime-acting-condition
383 Format of variable 'mime-acting-condition was changed from `atype'
384 to `condition tree'. Its format is as same as
385 'mime-preview-condition.
387 If there are two or more conditions are found when matching, menu
388 pops up to select method to run. Selected situation will be added to
389 example database. (cf. mime-acting-situation-examples-file)
393 *** mime-view-find-every-acting-situation
395 Find every available acting-situation if non-nil.
397 *** mime-acting-situation-examples-file
399 File name of example about acting-situation demonstrated by
403 * Changes in SEMI 1.2
409 'mime-view-plain-text-preview-hook was renamed to
410 'mime-preview-text/plain-hook.
414 Variable 'mime-view-childrens-header-showing-Content-Type-list was
415 abolished. Please use 'mime-preview-condition instead.
417 *** API about visible-predicates were abolished
419 Following functions were abolished:
421 mime-view-header-visible-p (entity message-info)
423 mime-view-body-visible-p (entity message-info)
425 mime-view-entity-separator-visible-p (entity message-info)
427 Please use 'mime-preview-condition instead.
429 Function 'mime-view-entity-button-visible-p is not abolished, but it
432 *** mime-preview-condition
434 Following are added as pre-defined keys:
436 'childrens-situation default preview-situation for children
437 'message-button to specify to display message-button
438 nil: default (invisible)
440 'invisible: invisible
441 'entity-button to specify to display entity-button
442 nil: default (visible)
444 'invisible: invisible
445 'header to specify to display header
446 nil: default (invisible)
448 'invisible: invisible
452 *** Interface for body-filter
454 'mime-view-filter-for-* was renamed to 'mime-preview-filter-for-*.
457 *** mime-text-decode-body
459 Function 'mime-decode-text-body was renamed to
460 'mime-text-decode-body and changed interface. New interface is
463 mime-text-decode-body (SITUATION)
465 SITUATION is preview-situation. Content-Transfer-Encoding and
466 MIME-charset are specified in field of it.
469 * Changes in SEMI 1.1
473 *** Setting variable about visible body
475 'mime-view-visible-media-type-list and
476 'mime-view-content-filter-alist were abolished. Please use
477 'mime-preview-condition instead.
479 Notice that 'mime-preview-condition is not list of
480 media-type/subtype string nor association-list. It uses new
481 data-structure `ctree' (condition-tree; it is introduced to replace
482 `atype'). Function 'ctree-set-calist-strictly and
483 'ctree-set-calist-with-default may be useful to modify it (`calist'
484 (condition-alist) is as same as `atype').
487 *** API about visible-predicates
489 Interface of visible-predicates for entity elements were changed.
490 New interfaces are following:
492 mime-view-entity-button-visible-p (entity message-info)
494 mime-view-header-visible-p (entity message-info)
496 mime-view-body-visible-p (entity message-info)
498 mime-view-entity-separator-visible-p (entity message-info)
503 *** entity representation
505 Structure 'mime-entity-info was renamed to 'mime-entity. So various
506 functions were renamed too.
509 *** Interface for entity-button generators
511 Interface of entity-button generators was changed. New interfaces
514 mime-view-insert-entity-button (entity message-info subject)
517 *** mime-preview-condition and preview-situation
519 Conditions about preview generation are unified to
520 'mime-preview-condition. Namely other variables, such as
521 'mime-view-visible-media-type-list, 'mime-view-content-filter-alist,
522 'mime-view-image-converter-alist were abolished.
524 Preview-situation is generated from entity information, running
525 environment and 'mime-preview-condition. These elements are checked
526 to match with each other. (it is similar to acting-situation)
528 Format of preview-situation is association-list. Following key is
532 'subtype media-subtype
533 'encoding content-transfer-encoding
534 'major-mode major-mode of MUA
535 <STRING> attribute of Content-Type field.
536 'body-presentation-method body-presentation-method
538 If 'body-presentation-method is 'with-filter, 'body-filter is used to
539 specify body-filter function. If 'body-presentation-method is
540 function, it is called to generate presentation of entity body.
542 Body-filter function 'mime-view-filter-for-image refers 'image-format.
544 Setting for message/partial button is specified by
545 'mime-preview-condition instead of hard-coding.
548 *** Interface for body-filter
550 Interface of body-filter was changed. New interfaces is following:
552 <body-filter> (situation)
554 Current pre-defined filters are following:
556 mime-view-filter-for-text/plain (situation)
557 mime-view-filter-for-text/richtext (situation)
558 mime-view-filter-for-text/enriched (situation)
559 mime-view-filter-for-image (situation) ; if available
561 'mime-view-filter-for-application/postscript was abolished.
564 *** Format of mime-acting-condition (acting-situation)
566 Format of `mime-acting-condition' were changed. `type' and
567 `subtype' are separated and changed to symbol.
572 - mime-view-buffer -> mime-preview-buffer
