6 ** Function `mime-play-entity'
8 Function `mime-play-entity' was renamed from `mime-raw-play-entity'
13 mime-play-entity (entity &optional situation ignored-method)
15 Please use `situation' if you would like to specify `mode' and
19 ** Now acting-method must not expect to run in raw-buffer
21 Function `mime-play-entity' was changed to permit to run in any buffer
22 (may be called in preview-buffer). So each acting-method is called in
26 ** Text property `mime-view-entity-{header|body}'
28 Now mime-view put text property `mime-view-entity-header' and
29 `mime-view-entity-body' in header and body of each entity.
32 ** Behavior change about `mime-display-header-hook'
34 Function `mime-display-entity' runs `mime-display-header-hook' before
37 In addition, now it is cleared that current point means beginning of
38 header when `mime-display-entity' runs `mime-display-header-hook'.
39 Therefore header-presentation-method must not change current point.
42 * Changes in SEMI 1.12
44 There are no user-visible changes.
46 ** New function `eliminate-top-spaces'
51 * Changes in SEMI 1.11
53 ** New function `mime-edit-decode-message-in-buffer'
55 Add new function `mime-edit-decode-message-in-buffer'. Function
56 `mime-edit-decode-buffer' was abolished.
59 ** Requires FLIM 1.12 API
62 * Changes in SEMI 1.10
64 ** Abolish variable `mime-temp-directory'
66 FLIM 1.11 and SEMI 1.10 use variable `temporary-file-directory'
67 instead of `mime-temp-directory'. So environment variable
68 "MIME_TMP_DIR" and "TM_TMP_DIR" are not effective to specify temporary
69 directory of FLIM and SEMI.
72 ** Abolish function `mime-text-insert-decoded-body'
74 SEMI 1.10 uses function `mime-insert-text-content' of FLIM 1.11 API
75 instead of `mime-text-insert-decoded-body'.
77 Now `mime-view-caesar' does not run `mime-text-decode-hook'.
82 ** User option `mime-encoding-list'
84 SEMI 1.9 requires FLIM 1.10 API. In FLIM 1.10 API, variable
85 `mime-file-encoding-method-alist' was abolished. If you want to use
86 non-standard Content-Transfer-Encoding to insert a file into sending
87 message, please edit new user option `mime-encoding-list' instead of
88 `mime-file-encoding-method-alist'.
91 ** Constant `mime-user-interface-product'
93 Constant `mime-user-interface-version' was renamed to
94 `mime-user-interface-product'. Notice that data format is changed
97 FLIM 1.10 API provides following macros to access a slot of the new
100 mime-product-name (product)
102 mime-product-version (product)
104 mime-product-code-name (product)
106 Please use them to get elements of the constant
107 `mime-user-interface-product'.
110 * Changes in SEMI 1.8
112 ** Don't use "file" command to detect content of entity
114 Acting-method to detect content of entity was modified not to use
117 Variable `mime-file-content-type-alist' was abolished. Instead of
118 it, new variable `mime-magic-type-alist' is available to customize.
119 It is an alist of regexp about magic-number vs. corresponding
120 media-types. Each element looks like (REGEXP TYPE SUBTYPE). REGEXP
121 is a regular expression to match against the beginning of the content
122 of entity. TYPE is symbol to indicate primary type of media-type.
123 SUBTYPE is symbol to indicate subtype of media-type.
126 ** Abolish external X-Face viewer
129 ** Abolish obsolete utility for *-field-list and *-field-regexp
131 Abolish function `tm:set-fields', `tm:add-fields' and
135 ** Change MUA interface of automatic message/partial combining
137 Abolish variable `mime-view-partial-message-method-alist'.
139 Instead of it, `request-partial-message-method' in acting-situation
140 is available to specify MUA depended implementation.
142 Each element of `mime-view-partial-message-method-alist' were
143 required to display message at current summary line, and its return
144 value were ignored. On the other hand,
145 `request-partial-message-method' is required to return structure of
146 message at current summary line. Format of it is mime-entity.
151 MIME-Edit inserts User-Agent field instaed of X-Emacs field if
152 `mime-edit-insert-user-agent-field' is not nil. Contents of
153 User-Agent is specified by mime-edit-user-agent-value'.
155 X-Emacs field related features were abolished.
158 * Changes in SEMI 1.7
160 ** Header-presentation-method
162 Now MIME-View uses header-presentation-method instead of
165 - abolish variable `mime-view-content-header-filter-alist'
167 - abolish function `mime-view-cut-header'
169 - Rename `mime-view-content-header-filter-hook' to
170 `mime-display-header-hook'
173 ** Abolish `mime-view-ignored-field-regexp'
175 Now mime-view uses `mime-view-ignored-field-list' directly in
176 default header-presentation-method.
179 ** Abolish body filter support
181 Please use body-presentation-method.
186 - Rename `mime-view-following-method-alist' to
187 `mime-preview-following-method-alist'
189 - Rename `mime-method-to-combine-message/partial-pieces' to
190 `mime-combine-message/partial-pieces-automatically'
193 * Changes in SEMI 1.6
195 ** Abolish tm-compatible external method support
197 Abolish tm-compatible external method support. Please use mailcap
198 method instead of it.
201 ** Abolish `mime-edit-signing-type' and `mime-edit-encrypting-type'
203 C-c C-m C-s encloses as "pgp-signed" which means PGP/MIME signature.
205 C-c C-m C-e encloses as "pgp-encrypted" which means PGP/MIME
209 ** New method to detect content of entity
211 Now MIME-View can detect content of entity for
212 application/octet-stream in default setting.
214 It uses "file" command to detect. User can customize
215 `mime-file-content-type-alist' to specify media-type for output of
216 "file" command. It is an alist of "file" output patterns
217 vs. corresponding media-types. Each element looks like (REGEXP TYPE
218 SUBTYPE). REGEXP is pattern for "file" command output. TYPE is
219 symbol to indicate primary type of media-type. SUBTYPE is symbol to
220 indicate subtype of media-type.
223 ** New interface to display message
225 - Function `mime-view-buffer'
226 - Function `mime-view-display-message'
229 ** Change interface of internal playback method
231 Interface of internal playback method was changed to
235 It is as same as interface of body-presentation-method.
238 ** Change interface of `mime-view-entity-button-visible-p'
240 ** Change interface of `mime-view-insert-entity-button'
243 ** `mime-preview-original-major-mode'
245 Abolish variable `mime-preview-original-major-mode'.
247 Please use function `mime-preview-original-major-mode' instead of
251 ** mime-preview-over-to-{previous|next}-method-alist
253 `mime-preview-over-to-{previous|next}-method-alist' were renamed
254 from `mime-view-over-to-{previous|next}-method-alist'.
257 * Changes in SEMI 1.5
261 Add inline text/html preview feature using w3. If
262 `mime-setup-enable-inline-html' is not nil, semi-setup.el sets up it.
265 ** `pgp-elkins' -> `pgp-mime'
267 Rename `pgp-elkins' -> `pgp-mime'. Variable
268 `mime-edit-signing-type' and `mime-edit-encrypting-type' does not
272 ** type-subtype-score
274 Now MIME-View chooses one entity to display body in
275 multipart/alternative. In this mechanism,
276 `mime-view-type-subtype-score-alist' is used to specify priority of
279 Variable `mime-view-type-subtype-score-alist' is alist of
280 TYPE-SUBTYPE vs. SCORE. TYPE-SUBTYPE is cons pair (TYPE . SUBTYPE),
281 symbol TYPE or t. TYPE and SUBTYPE are symbol. `t' means default.
282 SCORE is integer. Larger number is larger priority.
287 Change text presentation mechanism. In anything older than SEMI
288 1.4, text presentation mechanism is based on filter model. However it
289 has design problem about conversion between byte representation and
290 text presentation. So SEMI was changed to use
291 body-presentation-method to display text entity. In this purpose, old
292 text decoding features were abolished and introduces news features
296 ** mime-raw-representation-type and mime-raw-representation-type-alist
298 Abolish `mime-text-decoder' and `mime-text-decoder-alist' because of
299 text presentation mechanism change (cf. previous section). Instead of
300 it, SEMI introduces variable about representation-type of
301 mime-raw-buffer. If it is `binary', mime-raw-buffer is as same as
302 network representation. If it is `cooked', mime-raw-buffer is
305 `mime-raw-representation-type-alist' is an alist of major-mode
306 vs. representation-type. Each element looks like
308 (SYMBOL . REPRESENTATION-TYPE).
310 SYMBOL is major-mode or t. t means default.
312 `mime-raw-representation-type' is a buffer local variable of
313 mime-raw-buffer. If it is non-nil, it overrides
314 `mime-raw-representation-type-alist'.
316 In addition, `mime-raw-buffer-coding-system-alist' was abolished.
317 Because representation-type has enough information.
320 * Changes in SEMI 1.4
324 mailcap was supported to set up 'mime-acting-condition.
326 tm-external-method scripts written by born shell were abolished.
329 ** mime-add-condition
331 New function to set up 'mime-preview-condition and/or
332 'mime-acting-condition.
335 ** signature setting in semi-setup.el
337 Abolish MUA depended signature setting.
339 Setting for mail-mode were moved to mail-mime-setup.el.
342 * Changes in SEMI 1.3
344 ** mime-acting-condition
346 Format of variable 'mime-acting-condition was changed from `atype'
347 to `condition tree'. Its format is as same as
348 'mime-preview-condition.
350 If there are two or more conditions are found when matching, menu
351 pops up to select method to run. Selected situation will be added to
352 example database. (cf. mime-acting-situation-examples-file)
356 *** mime-view-find-every-acting-situation
358 Find every available acting-situation if non-nil.
360 *** mime-acting-situation-examples-file
362 File name of example about acting-situation demonstrated by
366 * Changes in SEMI 1.2
372 'mime-view-plain-text-preview-hook was renamed to
373 'mime-preview-text/plain-hook.
377 Variable 'mime-view-childrens-header-showing-Content-Type-list was
378 abolished. Please use 'mime-preview-condition instead.
380 *** API about visible-predicates were abolished
382 Following functions were abolished:
384 mime-view-header-visible-p (entity message-info)
386 mime-view-body-visible-p (entity message-info)
388 mime-view-entity-separator-visible-p (entity message-info)
390 Please use 'mime-preview-condition instead.
392 Function 'mime-view-entity-button-visible-p is not abolished, but it
395 *** mime-preview-condition
397 Following are added as pre-defined keys:
399 'childrens-situation default preview-situation for children
400 'message-button to specify to display message-button
401 nil: default (invisible)
403 'invisible: invisible
404 'entity-button to specify to display entity-button
405 nil: default (visible)
407 'invisible: invisible
408 'header to specify to display header
409 nil: default (invisible)
411 'invisible: invisible
415 *** Interface for body-filter
417 'mime-view-filter-for-* was renamed to 'mime-preview-filter-for-*.
420 *** mime-text-decode-body
422 Function 'mime-decode-text-body was renamed to
423 'mime-text-decode-body and changed interface. New interface is
426 mime-text-decode-body (SITUATION)
428 SITUATION is preview-situation. Content-Transfer-Encoding and
429 MIME-charset are specified in field of it.
432 * Changes in SEMI 1.1
436 *** Setting variable about visible body
438 'mime-view-visible-media-type-list and
439 'mime-view-content-filter-alist were abolished. Please use
440 'mime-preview-condition instead.
442 Notice that 'mime-preview-condition is not list of
443 media-type/subtype string nor association-list. It uses new
444 data-structure `ctree' (condition-tree; it is introduced to replace
445 `atype'). Function 'ctree-set-calist-strictly and
446 'ctree-set-calist-with-default may be useful to modify it (`calist'
447 (condition-alist) is as same as `atype').
450 *** API about visible-predicates
452 Interface of visible-predicates for entity elements were changed.
453 New interfaces are following:
455 mime-view-entity-button-visible-p (entity message-info)
457 mime-view-header-visible-p (entity message-info)
459 mime-view-body-visible-p (entity message-info)
461 mime-view-entity-separator-visible-p (entity message-info)
466 *** entity representation
468 Structure 'mime-entity-info was renamed to 'mime-entity. So various
469 functions were renamed too.
472 *** Interface for entity-button generators
474 Interface of entity-button generators was changed. New interfaces
477 mime-view-insert-entity-button (entity message-info subject)
480 *** mime-preview-condition and preview-situation
482 Conditions about preview generation are unified to
483 'mime-preview-condition. Namely other variables, such as
484 'mime-view-visible-media-type-list, 'mime-view-content-filter-alist,
485 'mime-view-image-converter-alist were abolished.
487 Preview-situation is generated from entity information, running
488 environment and 'mime-preview-condition. These elements are checked
489 to match with each other. (it is similar to acting-situation)
491 Format of preview-situation is association-list. Following key is
495 'subtype media-subtype
496 'encoding content-transfer-encoding
497 'major-mode major-mode of MUA
498 <STRING> attribute of Content-Type field.
499 'body-presentation-method body-presentation-method
501 If 'body-presentation-method is 'with-filter, 'body-filter is used to
502 specify body-filter function. If 'body-presentation-method is
503 function, it is called to generate presentation of entity body.
505 Body-filter function 'mime-view-filter-for-image refers 'image-format.
507 Setting for message/partial button is specified by
508 'mime-preview-condition instead of hard-coding.
511 *** Interface for body-filter
513 Interface of body-filter was changed. New interfaces is following:
515 <body-filter> (situation)
517 Current pre-defined filters are following:
519 mime-view-filter-for-text/plain (situation)
520 mime-view-filter-for-text/richtext (situation)
521 mime-view-filter-for-text/enriched (situation)
522 mime-view-filter-for-image (situation) ; if available
524 'mime-view-filter-for-application/postscript was abolished.
527 *** Format of mime-acting-condition (acting-situation)
529 Format of `mime-acting-condition' were changed. `type' and
530 `subtype' are separated and changed to symbol.
535 - mime-view-buffer -> mime-preview-buffer
540 paragraph-separate: "[
