  28
  29 ;; All gnus-uu commands start with `C-c C-v'.
  30 ;;
  31 ;; Short user manual for this package:
  32 ;;
  33 ;; Type `C-c C-v C-v' to decode and view all articles of the current
  34 ;; series. The defaults should be reasonable for most systems.
  35 ;;
  36 ;; Type `C-c C-v C-i' to toggle interactive mode. When using
  37 ;; interactive mode, gnus-uu will which display a buffer that will let
  38 ;; you see the suggested commands to be executed.
  39 ;;
  40 ;; To post an uuencoded file, type `C-c C-v p', which will enter you
  41 ;; into a buffer analogous to the one you will get when typing `a'. Do
  42 ;; an `M-x describe-mode' in this buffer to get a description of what
  43 ;; this buffer lets you do.
  44 ;;
  45 ;; Read the documentation of the `gnus-uu' dummy function for a more
  46 ;; complete description of what this package does and how you can
  47 ;; customize it to fit your needs.

  51 ;; History
  52 ;;
  53 ;; v1.0: First version released Oct 2 1992.
  54 ;;
  55 ;; v1.1: Changed `C-c C-r' to `C-c C-e' and `C-c C-p' to `C-c C-k'.
  56 ;; Changed (setq gnus-exit-group-hook) to (add-hook).  Removed
  57 ;; checking for "Re:" for finding parts.
  58 ;;
  59 ;; v2.2: Fixed handling of currupted archives. Changed uudecoding to
  60 ;; an asynchronous process to avoid loading tons of data into emacs
  61 ;; buffers. No longer reads articles emacs already have aboard.  Fixed
  62 ;; a firmer support for shar files. Made regexp searches for files
  63 ;; more convenient. Added `C-c C-l' for editing uucode begin
  64 ;; lines. Added multi-system decoder entry point. Added interactive
  65 ;; view mode. Added function for decoding and saving all uuencoded
  66 ;; articles in the current newsgroup.
  67 ;;
  68 ;; v2.3: After suggestions I have changed all the gnus-uu key bindings
  69 ;; to avoid hogging all the user keys (C-c LETTER). Also added
  70 ;; (provide) and fixed some saving stuff. First posted version to
  71 ;; gnu.emacs.sources.
  72 ;;
  73 ;; v2.4: Fixed some more in the save-all category. Automatic fixing of
  74 ;; uucode "begin" lines: names on the form of "dir/file" are
  75 ;; translated into "dir-file". Added a function for fixing stripped
  76 ;; uucode articles. Added binhex save.
  77 ;;
  78 ;; v2.5: First version copyrighted by FSF. Changed lots of
  79 ;; documentation strings.
  80 ;;
  81 ;; v2.5.1: Added uuencode/posting code to post binary files.
  82 ;;
  83 ;; v2.6: Thread support. gnus-uu is now able to decode uuencoded files
  84 ;; posted in threads. gnus-uu can also post in threads. I don't know
  85 ;; if this ability is of much use - I've never seen anyone post
  86 ;; uuencoded files in threads.
  87 ;;
  88 ;; v2.7: gnus-uu is now able to decode (and view/save) multiple
  89 ;; encoded files in one big gulp. Also added pseudo-mime support
  90 ;; (users can use metamail to view files), posting uuencoded/mime
  91 ;; files and various other bits and pieces.
  92 ;;
  93 ;; v2.7.1: New functions for decoding/saving threads bound to `C-c
  94 ;; C-v C-j'. Handy to save entire threads, not very useful for
  95 ;; decoding, as nobody posts encoded files in threads...
  96 ;;
  97 ;; v2.7.2: New functions for digesting and forwarding articles added
  98 ;; on the suggestion of Per Abrahamsen. Also added a function for
  99 ;; marking threads.
 100 ;;
 101 ;; v2.8: Fixed saving original files in interactive mode. Fixed ask
 102 ;; before/save after view. Fixed setting up interactive buffers. Added
 103 ;; scanning and rescanning from interactive mode. Added the
 104 ;; `gnus-uu-ignore-file-by-name' and `...-by-type' variables to allow
 105 ;; users to sift files they don't want to view. At the suggestion of
 106 ;; boris@cs.rochester.edu, `C-c C-v C-h' has been undefined to allow
 107 ;; users to view list of binding beginning with `C-c C-v'. Fixed
 108 ;; viewing with `gnus-uu-asynchronous' set. The
 109 ;; "decode-and-save/view-all-articles" functions now accepts the
 110 ;; numeric prefix to delimit the maximum number of files to be
 111 ;; decoded.

 225 Function description:
 226
 227 `gnus-uu-decode-and-view' will try to find all articles in the same
 228 series, uudecode them and view the resulting file(s).
 229
 230 gnus-uu guesses what articles are in the series according to the
 231 following simplish rule: The subjects must be (nearly) identical,
 232 except for the last two numbers of the line. (Spaces are largely
 233 ignored, however.)
 234
 235 For example: If you choose a subject called
 236   \"cat.gif (2/3)\"
 237 gnus-uu will find all the articles that matches
 238   \"^cat.gif ([0-9]+/[0-9]+).*$\".
 239
 240 Subjects that are nonstandard, like
 241   \"cat.gif (2/3) Part 6 of a series\",
 242 will not be properly recognized by any of the automatic viewing
 243 commands, and you have to mark the articles manually with '#'.
 244
 245 `gnus-uu-decode-and-save' will do the same as
 246 `gnus-uu-decode-and-view', except that it will not display the
 247 resulting file, but save it instead.
 248
 249 `gnus-uu-shar-and-view' and `gnus-uu-shar-and-save' are the \"shar\"
 250 equivalents to the uudecode functions. Instead of feeding the articles
 251 to uudecode, they are run through /bin/sh. Most shar files can be
 252 viewed and/or saved with the normal uudecode commands, which is much
 253 safer, as no foreign code is run.
 254
 255 Instead of having windows popping up automatically, it can be handy to
 256 view files interactivly, especially when viewing archives. Use
 257 `gnus-uu-toggle-interactive-mode' to toggle interactive mode.
 258
 259 `gnus-uu-mark-article' marks an article for later
 260 decoding/unsharing/saving/viewing. The files will be decoded in the
 261 sequence they were marked. To decode the files after you've marked the
 262 articles you are interested in, type the corresponding key strokes as
 263 the normal decoding commands, but put a `M-' in the last
 264 keystroke. For instance, to perform a standard uudecode and view, you
 265 would type `C-c C-v C-v'. To perform a marked uudecode and view, say
 266 `C-v C-v M-C-v'. All the other view and save commands are handled the
 267 same way; marked uudecode and save is then `C-c C-v M-v'.
 268
 269 `gnus-uu-unmark-article' will remove the mark from a previosly marked
 270 article.
 271
 272 `gnus-uu-unmark-all-articles' will remove the mark from all marked
 273 articles.
 274
 275 `gnus-uu-mark-by-regexp' will prompt for a regular expression and mark
 276 all articles matching that regular expression.
 277
 278 `gnus-uu-mark-thread' will mark all articles downward in the current
 279 thread.
 280
 281 There's an additional way to reach the decoding functions to make
 282 future expansions easier: `gnus-uu-multi-decode-and-view' and the
 283 corresponding save, marked view and marked save functions. You will be
 284 prompted for a decoding method, like uudecode, shar, binhex or plain
 285 save. Note that methods like binhex and save doesn't have view modes;
 286 even if you issue a view command (`C-c C-v C-m' and \"binhex\"),
 287 gnus-uu will just save the resulting binhex file.
 288
 289 `gnus-uu-decode-and-show-in-buffer' will decode the current article
 290 and display the results in an emacs buffer. This might be useful if
 291 there's jsut some text in the current article that has been uuencoded
 292 by some perverse poster.
 293
 294 `gnus-uu-decode-and-save-all-articles' looks at all the articles in
 295 the current newsgroup and tries to uudecode everything it can
 296 find. The user will be prompted for a directory where the resulting
 297 files (if any) will be
 298 saved. `gnus-uu-decode-and-save-unread-articles' does only checks
 299 unread articles.
 300
 301 `gnus-uu-decode-and-view-all-articles' does the same as the function
 302 above, only viewing files instead of saving them.
 303
 304 `gnus-uu-edit-begin-line' lets you edit the begin line of an uuencoded
 305 file in the current article. Useful to change a corrupted begin line.
 306
 307
 308 When using the view commands, `gnus-uu-decode-and-view' for instance,
 309 gnus-uu will (normally, see below) try to view the file according to
 310 the rules given in `gnus-uu-default-view-rules' and
 311 `gnus-uu-user-view-rules'. If it recognizes the file, it will display
 312 it immediately. If the file is some sort of archive, gnus-uu will
 313 attempt to unpack the archive and see if any of the files in the
 314 archive can be viewed. For instance, if you have a gzipped tar file
 315 \"pics.tar.gz\" containing the files \"pic1.jpg\" and \"pic2.gif\",
 316 gnus-uu will uncompress and detar the main file, and then view the two
 317 pictures. This unpacking process is recursive, so if the archive
 318 contains archives of archives, it'll all be unpacked.
 319
 320 If the view command doesn't recognise the file type, or can't view it
 321 because you don't have the viewer, or can't view *any* of the files in
 322 the archive, the user will be asked if she wishes to have the file
 323 saved somewhere. Note that if the decoded file is an archive, and
 324 gnus-uu manages to view some of the files in the archive, it won't
 325 tell the user that there were some files that were unviewable. Try
 326 interactive view for a different approach.
 327
 328
 329 Note that gnus-uu adds a function to `gnus-exit-group-hook' to clear
 330 the list of marked articles and check for any generated files that
 331 might have escaped deletion if the user typed `C-g' during viewing.
 332
 333
 334 `gnus-uu-toggle-asynchronous' toggles the `gnus-uu-asynchronous'
 335 variable.
 336
 337 `gnus-uu-toggle-query' toggles the `gnus-uu-ask-before-view'
 338 variable.
 339
 340 `gnus-uu-toggle-always-ask' toggles the `gnus-uu-view-and-save'
 341 variable.
 342
 343 `gnus-uu-toggle-kill-carriage-return' toggles the
 344 `gnus-uu-kill-carriage-return' variable.
 345
 346 `gnus-uu-toggle-interactive-view' toggles interactive mode. If it is
 347 turned on, gnus-uu won't view files immediately, but will give you a
 348 buffer with the default commands and files and let you edit the
 349 commands and execute them at leisure.
 350
 351 `gnus-uu-toggle-correct-stripped-articles' toggles whether to check
 352 and correct uuencoded articles that may have had trailing spaces
 353 stripped by mailers.
 354
 355 `gnus-uu-toggle-view-with-metamail' toggles whether to skip the
 356 gnus-uu viewing methods and just guess at an content-type based on the
 357 file name suffix and feed it to metamail.
 358
 359 `gnus-uu-toggle-any-variable' is an interface to the toggle commands
 360 listed above.
 361
 362
 363 Customization
 364
 365    Rule Variables
 366
 367    gnus-uu uses \"rule\" variables to decide how to view a file. All
 368    these variables are of the form
 369
 370       (list '(regexp1 command2)
 371             '(regexp2 command2)
 372             ...)
 373
 374    `gnus-uu-user-view-rules'
 375      This variable is consulted first when viewing files. If you wish
 376      to use, for instance, sox to convert an .au sound file, you could
 377      say something like:
 378
 379        (setq gnus-uu-user-view-rules
 380          (list '(\"\\\\.au$\" \"sox %s -t .aiff > /dev/audio\")))
 381
 382    `gnus-uu-user-view-rules-end'
 383      This variable is consulted if gnus-uu couldn't make any matches
 384      from the user and default view rules.
 385
 386    `gnus-uu-user-interactive-view-rules'
 387      This is the variable used instead of `gnus-uu-user-view-rules'
 388      when in interactive mode.
 389
 390    `gnus-uu-user-interactive-view-rules-end'
 391      This variable is used instead of `gnus-uu-user-view-rules-end'
 392      when in interactive mode.
 393
 394    `gnus-uu-user-archive-rules`
 395      This variable can be used to say what comamnds should be used to
 396      unpack archives.
 397
 398
 399    Other Variables
 400
 401    `gnus-uu-ignore-files-by-name'
 402      Files with name matching this regular expression won't be viewed.
 403
 404    `gnus-uu-ignore-files-by-type'
 405      Files with a MIME type matching this variable won't be viewed.
 406      Note that gnus-uu tries to guess what type the file is based on
 407      the name. gnus-uu is not a MIME package, so this is slightly
 408      kludgy.
 409
 410    `gnus-uu-tmp-dir'
 411      Where gnus-uu does its work.
 412
 413    `gnus-uu-do-not-unpack-archives'
 414      Non-nil means that gnus-uu won't peek inside archives looking for
 415      files to dispay.
 416
 417    `gnus-uu-view-and-save'
 418      Non-nil means that the user will always be asked to save a file
 419      after viewing it.
 420
 421    `gnus-uu-asynchronous'
 422      Non-nil means that files will be viewed asynchronously.  This can
 423      be useful if you're viewing long .mod files, for instance, which
 424      often takes several minutes. Note, however, that since gnus-uu
 425      doesn't ask, and if you are viewing an archive with lots of
 426      viewable files, you'll get them all up more or less at once,
 427      which can be confusing, to say the least. To get gnus-uu to ask
 428      you before viewing a file, set the `gnus-uu-ask-before-view'
 429      variable.
 430
 431    `gnus-uu-ask-before-view'
 432      Non-nil means that gnus-uu will ask you before viewing each file
 433
 434    `gnus-uu-ignore-default-view-rules'
 435      Non-nil means that gnus-uu will ignore the default viewing rules.
 436
 437    `gnus-uu-ignore-default-archive-rules'
 438      Non-nil means that gnus-uu will ignore the default archive
 439      unpacking commands.
 440
 441    `gnus-uu-kill-carriage-return'
 442      Non-nil means that gnus-uu will strip all carriage returns from
 443      articles.
 444
 445    `gnus-uu-unmark-articles-not-decoded'
 446      Non-nil means that gnus-uu will mark articles that were
 447      unsuccessfully decoded as unread.
 448
 449    `gnus-uu-output-window-height'
 450      This variable says how tall the output buffer window is to be
 451      when using interactive view mode.
 452
 453    `gnus-uu-correct-stripped-uucode'
 454      Non-nil means that gnus-uu will *try* to fix uuencoded files that
 455      have had traling spaces deleted.
 456
 457    `gnus-uu-use-interactive-view'
 458      Non-nil means that gnus-uu will use interactive viewing mode.
 459
 460    `gnus-uu-view-with-metamail'
 461      Non-nil means that gnus-uu will ignore the viewing commands
 462      defined by the rule variables and just fudge a MIME content type
 463      based on the file name. The result will be fed to metamail for
 464      viewing.
 465
 466    `gnus-uu-save-in-digest'
 467      Non-nil means that gnus-uu, when asked to save without decoding,
 468      will save in digests.  If this variable is nil, gnus-uu will just
 469      save everything in a file without any embellishments. The
 470      digesting almost conforms to RFC1153 - no easy way to specify any
 471      meaningful volume and issue numbers were found, so I simply
 472      dropped them.
 473
 474    `gnus-uu-post-include-before-composing'
 475      Non-nil means that gnus-uu will ask for a file to encode before
 476      you compose the article.  If this variable is t, you can either
 477      include an encoded file with \\<gnus-uu-post-reply-mode-map>\\[gnus-uu-post-insert-binary-in-article] or have one included for you when you
 478      post the article.
 479
 480    `gnus-uu-post-length'
 481      Maximum length of an article.  The encoded file will be split
 482      into how many articles it takes to post the entire file.
 483
 484    `gnus-uu-post-threaded'
 485      Non-nil means that gnus-uu will post the encoded file in a
 486      thread.  This may not be smart, as no other decoder I have seen
 487      are able to follow threads when collecting uuencoded
 488      articles. (Well, I have seen one package that does that -
 489      gnus-uu, but somehow, I don't think that counts...) Default is
 490      nil.
 491
 492    `gnus-uu-post-separate-description'
 493      Non-nil means that the description will be posted in a separate
 494      article.  The first article will typically be numbered (0/x). If
 495      this variable is nil, the description the user enters will be
 496      included at the beginning of the first article, which will be
 497      numbered (1/x). Default is t.

 523 To change the behaviour, you can either edit this variable or set
 524 `gnus-uu-user-view-rules' to something useful.
 525
 526 For example:
 527
 528 To make gnus-uu use 'xli' to display JPEG and GIF files, put the
 529 following in your .emacs file
 530
 531   (setq gnus-uu-user-view-rules (list '(\"jpg$\\\\|gif$\" \"xli\")))
 532
 533 Both these variables are lists of lists with two string elements. The
 534 first string is a regular expression. If the file name matches this
 535 regular expression, the command in the second string is executed with
 536 the file as an argument.
 537
 538 If the command string contains \"%s\", the file name will be inserted
 539 at that point in the command string. If there's no \"%s\" in the
 540 command string, the file name will be appended to the command string
 541 before executing.
 542
 543 There are several user variables to tailor the behaviour of gnus-uu to
 544 your needs. First we have `gnus-uu-user-view-rules', which is the
 545 variable gnus-uu first consults when trying to decide how to view a
 546 file. If this variable contains no matches, gnus-uu examines the
 547 default rule vaiable provided in this package. If gnus-uu finds no
 548 match here, it uses `gnus-uu-user-view-rules-end' to try to make a
 549 match.
 550
 551 Unless, of course, you are using the interactive view mode. Then
 552 `gnus-uu-user-interactive-view-rules' and
 553 `gnus-uu-user-interactive-view-rules-end' will be used instead.")

2742
2743    `gnus-uu-post-encode-method'
2744    There are three functions supplied with gnus-uu for encoding files:
2745    `gnus-uu-post-encode-uuencode', which does straight uuencoding;
2746    `gnus-uu-post-encode-mime', which encodes with base64 and adds MIME
2747    headers; and `gnus-uu-post-encode-mime-uuencode', which encodes with
2748    uuencode and adds MIME headers.
2749
2750    `gnus-uu-post-include-before-composing'
2751    Non-nil means that gnus-uu will ask for a file to encode before you
2752    compose the article.  If this variable is t, you can either include
2753    an encoded file with `C-c C-i' or have one included for you when you
2754    post the article.
2755
2756    `gnus-uu-post-length'
2757    Maximum length of an article. The encoded file will be split into how
2758    many articles it takes to post the entire file.
2759
2760    `gnus-uu-post-separate-description'
2761    Non-nil means that the description will be posted in a separate
2762    article. The first article will typically be numbered (0/x). If
2763    this variable is nil, the description the user enters will be
2764    included at the beginning of the first article, which will be
2765    numbered (1/x). Default is t.
2766
2767    `gnus-uu-post-threaded'
2768    Non-nil means that gnus-uu will post the encoded file in a thread.
2769    This may not be smart, as no other decoder I have seen are able to
2770    follow threads when collecting uuencoded articles. (Well, I have seen
2771    one package that does that - gnus-uu, but somehow, I don't think that
2772    counts...) Default is nil.
