545 "A function to save articles in your favorite format.
546 The function will be called by way of the `gnus-summary-save-article'
547 command, and friends such as `gnus-summary-save-article-rmail'.
549 Gnus provides the following functions:
551 * gnus-summary-save-in-rmail (Rmail format)
552 * gnus-summary-save-in-mail (Unix mail format)
553 * gnus-summary-save-in-folder (MH folder)
554 * gnus-summary-save-in-file (article format)
555 * gnus-summary-save-body-in-file (article body)
556 * gnus-summary-save-in-vm (use VM's folder format)
557 * gnus-summary-write-to-file (article format -- overwrite)
558 * gnus-summary-write-body-to-file (article body -- overwrite)
559 * gnus-summary-save-in-pipe (article format)
561 The symbol of each function may have the following properties:
563 * :decode
564 The value non-nil means save decoded articles. This is meaningful
565 only with `gnus-summary-save-in-file', `gnus-summary-save-body-in-file',
566 `gnus-summary-write-to-file', `gnus-summary-write-body-to-file', and
567 `gnus-summary-save-in-pipe'.
569 * :function
570 The value specifies an alternative function which appends, not
571 overwrites, articles to a file. This implies that when saving many
572 articles at a time, `gnus-prompt-before-saving' is bound to t and all
573 articles are saved in a single file. This is meaningful only with
574 `gnus-summary-write-to-file' and `gnus-summary-write-body-to-file'.
576 * :headers
577 The value specifies the symbol of a variable of which the value
578 specifies headers to be saved. If it is omitted,
579 `gnus-save-all-headers' and `gnus-saved-headers' control what
580 headers should be saved."
598 "Coding system used to save decoded articles to a file.
600 The recommended coding systems are `utf-8', `iso-2022-7bit' and so on,
601 which can safely encode any characters in text. This is used by the
602 commands including:
604 * gnus-summary-save-article-file
605 * gnus-summary-save-article-body-file
606 * gnus-summary-write-article-file
607 * gnus-summary-write-article-body-file
609 and the functions to which you may set `gnus-default-article-saver':
611 * gnus-summary-save-in-file
612 * gnus-summary-save-body-in-file
613 * gnus-summary-write-to-file
614 * gnus-summary-write-body-to-file
616 Those commands and functions save just text displayed in the article
617 buffer to a file if the value of this variable is non-nil. Note that
618 buttonized MIME parts will be lost in a saved file in that case.
619 Otherwise, raw articles will be saved."

635 The function is called with NEWSGROUP, HEADERS, and optional LAST-FILE."

662 For instance, if you would like to save articles related to Gnus in
664 you could set this variable to something like:
669 This variable is an alist where the key is the match and the
670 value is a list of possible files to save in if the match is
671 non-nil.
673 If the match is a string, it is used as a regexp match on the
674 article. If the match is a symbol, that symbol will be funcalled
675 from the buffer of the article to be saved with the newsgroup as the
676 parameter. If it is a list, it will be evalled in the same buffer.
678 If this form or function returns a string, this string will be used as a
679 possible file name; and if it returns a non-nil list, that list will be
