This is Info file ../info/supercite.info, produced by Makeinfo-1.55 from the input file supercite.texinfo. This document describes the Supercite Version 3.1 package for citing and attributing the replies for various GNU Emacs mail and news reading subsystems. Copyright (C) 1993 Barry A. Warsaw Permission is granted to make and distribute verbatim copies of this manual provided the copyright notice and this permission notice are preserved on all copies. File: supercite.info, Node: Attribution Preferences, Next: Anonymous Attributions, Prev: Selecting an Attribution, Up: Selecting an Attribution Attribution Preferences ======================= When you cite an original message, you can tell Supercite which part of the author's name you would prefer it to use as the attribution. The variable `sc-preferred-attribution-list' controls this; it contains keys which are matched against the attribution alist in the given order. The first value of a key that produces a non-`nil', non-empty string match is used as the attribution string, and if no keys match, a secondary mechanism is used to generate the attribution. *Note Anonymous Attributions::. The following preferences are always available in the attribution alist (barring error): `"emailname"' the author's email terminus. `"initials"' the author's initials. `"firstname"' the author's first name. `"lastname"' the author's last name. `"middlename-1"' the author's first middle name. `"sc-lastchoice"' the last attribution string you have selected. This is useful when you recite paragraphs in the reply. `"sc-consult"' consults the customizable list `sc-attrib-selection-list' which can be used to select special attributions based on the value of any info key. See below for details. `"x-attribution"' the original author's suggestion for attribution string choice. See below for details. Middle name indexes can be any positive integer greater than zero, though it is unlikely that many authors will have more than one middle name, if that many. At this point, let me digress into a discussion of etiquette. It is my belief that while the style of the citations is a reflection of the personal tastes of the replier (i.e., you), the attribution selection is ultimately the personal choice of the original author. In a sense it is his or her "net nickname", and therefore the author should have some say in the selection of attribution string. Imagine how you would feel if someone gave you a nickname that you didn't like? For this reason, Supercite recognizes a special mail header, `X-Attribution:', which if present, tells Supercite the attribution string preferred by the original author. It is the value of this header that is associated with the `"x-attribution"' key in the attribution alist. Currently, you can override the preference of this key by changing `sc-preferred-attribution-list', but that isn't polite, and in the future Supercite may hard-code this. For now, it is suggested that if you change the order of the keys in this list, that `"x-attribution"' always be first, or possible second behind only `"sc-lastchoice"'. This latter is the default. The value `"sc-consult"' in `sc-preferred-attribution-list' has a special meaning during attribution selection. When Supercite encounters this preference, it begins processing a customizable list of attributions, contained in the variable `sc-attrib-selection-list'. Each element in this list contains lists of the following form: (INFOKEY ((REGEXP . ATTRIBUTION) (REGEXP . ATTRIBUTION) (...))) where INFOKEY is a key for `sc-mail-field' and REGEXP is a regular expression to match against the INFOKEY's value. If REGEXP matches the INFOKEY's value, the ATTRIBUTION is used as the attribution string. Actually, ATTRIBUTION can be a string or a list; if it is a list, it is `eval'uated and the return value (which must be a string), is used as the attribution. This can be very useful for when you are replying to net acquaintances who do not use the `X-Attribution:' mail header. You may know what nickname they would prefer to use, and you can set up this list to match against a specific mail field, e.g., `From:', allowing you to cite your friend's message with the appropriate attribution. File: supercite.info, Node: Anonymous Attributions, Next: Author Names, Prev: Attribution Preferences, Up: Selecting an Attribution Anonymous Attributions ====================== When the author's name cannot be found in the `From:' mail header, a fallback author name and attribution string must be supplied. The fallback author name is contained in the variable `sc-default-author-name' and the fallback attribution string is contained in the variable `sc-default-attribution'. Default values for these variables are `"Anonymous"' and `"Anon"', respectively. Note that in most circumstances, getting the default author name or attribution is a sign that something is set up incorrectly. Also, if the preferred attribution, which you specified in your `sc-preferred-attribution-alist' variable cannot be found, a secondary method can be employed to find a valid attribution string. The variable `sc-use-only-preference-p' controls what happens in this case. If the variable's value is non-`nil', then `sc-default-author-name' and `sc-default-attribution' are used, otherwise, the following steps are taken to find a valid attribution string, and the first step to return a non-`nil', non-empty string becomes the attribution: 1. Use the last selected attribution, if there is one. 2. Use the value of the `"x-attribution"' key. 3. Use the author's first name. 4. Use the author's last name. 5. Use the author's initials. 6. Find the first non-`nil', non-empty attribution string in the attribution alist. 7. `sc-default-attribution' is used. Once the attribution string has been automatically selected, a number of things can happen. If the variable `sc-confirm-always-p' is non-`nil', you are queried for confirmation of the chosen attribution string. The possible values for completion are those strings in the attribution alist, however you are not limited to these choices. You can type any arbitrary string at the confirmation prompt. The string you enter becomes the value associated with the `"sc-lastchoice"' key in the attribution alist. Once an attribution string has been selected, Supercite will force the string to lower case if the variable `sc-downcase-p' is non-`nil'. Two hook variables provide even greater control of the attribution selection process. The hook `sc-attribs-preselect-hook' is run before any attribution is selected. Likewise, the hook `sc-attribs-postselect-hook' is run after the attribution is selected (and the corresponding citation string is built), but before these values are committed for use by Supercite. During the post-selection hook, the local variables `attribution' and `citation' are bound to the appropriate strings. By changing these variables in your hook functions, you change the attribution and citation strings used by Supercite. One possible use of this would be to override any automatically derived attribution string when it is only one character long; e.g. you prefer to use `"initials"' but the author only has one name. File: supercite.info, Node: Author Names, Next: Configuring the Citation Engine, Prev: Anonymous Attributions, Up: Selecting an Attribution Author Names ============ Supercite employs a number of heuristics to decipher the author's name based on value of the `From:' mail field of the original message. Supercite can recognize almost all of the common `From:' field formats in use. If you encounter a `From:' field that Supercite cannot parse, please report this bug. *Note The Supercite Mailing List::. There are a number of Supercite variables that control how author names are extracted from the `From:' header. Some headers may contain a descriptive title as in: From: computer!speedy!doe (John Xavier-Doe -- Decent Hacker) Supercite knows which part of the `From:' header is email address and which part is author name, but in this case the string `"Decent Hacker"' is not part of the author's name. You can tell Supercite to ignore the title, while still recognizing hyphenated names through the use of a regular expression in the variable `sc-titlecue-regexp'. This variable has the default value of `"\\\\s +-+\\\\s +"'. Any text after this regexp is encountered is ignored as noise. Some `From:' headers may contain extra titles in the name fields not separated by a title cue, but which are nonetheless not part of the author's name proper. Examples include the titles "Dr.", "Mr.", "Ms.", "Jr.", "Sr.", and "III" (e.g., Thurston Howe, the Third). Also, some companies prepend or append the name of the division, organization, or project on the author's name. All of these titles are noise which should be ignored. The variable `sc-name-filter-alist' is used for this purpose. As implied by its name, this variable is an association list, where each element is a cons cell of the form: (REGEXP . POSITION) where REGEXP is a regular expression that is matched (using `string-match') against each element of the `From:' field's author name. POSITION is a position indicator, starting at zero. Thus to strip out all titles of "Dr.", "Mr.", etc. from the name, `sc-name-filter-alist' would have an entry such as: ("^\$Mr\\|Mrs\\|Ms\\|Dr\$[.]?$" . 0) which only removes them if they appear as the first word in the name. The position indicator is an integer, or one of the two special symbols `last' or `any'. `last' always matches against the last word in the name field, while `any' matches against every word in the name field. File: supercite.info, Node: Configuring the Citation Engine, Next: Using Regi, Prev: Author Names, Up: Top Configuring the Citation Engine ******************************* At the heart of Supercite is a regular expression interpreting engine called "Regi". Regi operates by interpreting a data structure called a Regi-frame (or just "frame"), which is a list of Regi-entries (or just "entry"). Each entry contains a predicate, typically a regular expression, which is matched against a line of text in the current buffer. If the predicate matches true, an associated expression is `eval'uated. In this way, an entire region of text can be transformed in an *awk*-like manner. Regi is used throughout Supercite, from mail header information extraction, to header nuking, to citing text. * Menu: * Using Regi:: * Frames You Can Customize:: While the details of Regi are discussed below (*note Using Regi::.), only those who wish to customize certain aspects of Supercite need concern themselves with it. It is important to understand though, that any conceivable citation style that can be described by a regular expression can be recognized by Supercite. This leads to some interesting applications. For example, if you regularly recieve email from a co-worker that uses an uncommon citation style (say one that employs a `|' or `}' character at the front of the line), it is possible for Supercite to recognize this and *coerce* the citation to your preferred style, for consistency. In theory, it is possible for Supercite to recognize such things as uuencoded messages or C code and cite or fill those differently than normal text. None of this is currently part of Supercite, but contributions are welcome! File: supercite.info, Node: Using Regi, Next: Frames You Can Customize, Prev: Configuring the Citation Engine, Up: Configuring the Citation Engine Using Regi ========== Regi works by interpreting frames with the function `regi-interpret'. A frame is a list of arbitrary size where each element is a entry of the following form: (PRED FUNC [NEGATE-P [CASE-FOLD-SEARCH]]) Regi starts with the first entry in a frame, evaluating the PRED of that entry against the beginning of the line that `point' is on. If the PRED evaluates to true (or false if the optional NEGATE-P is non-`nil'), then the FUNC for that entry is `eval'uated. How processing continues is determined by the return value for FUNC, and is described below. If PRED was false the next entry in the frame is checked until all entries have been matched against the current line. If no entry matches, `point' is moved forward one line and the frame is reset to the first entry. PRED can be a string, a variable, a list or one of the following symbols: `t', `begin', `end', or `every'. If PRED is a string, or a variable or list that `eval'uates to a string, it is interpreted as a regular expression. This regexp is matched against the current line, from the beginning, using `looking-at'. This match folds case if the optional CASE-FOLD-SEARCH is non-`nil'. If PRED is not a string, or does not `eval'uate to a string, it is interpreted as a binary value (`nil' or non-`nil'). The four special symbol values for PRED are recognized: `t' Always produces a true outcome. `begin' Always executed before the frame is interpreted. This can be used to initialize some global variables for example. `end' Always executed after frame interpreting is completed. This can be used to perform any necessary post-processing. `every' Executes whenever the frame is reset, usually after the entire frame has been matched against the current line. Note that NEGATE-P and CASE-FOLD-SEARCH are ignored if PRED is one of these special symbols. Only the first occurance of each symbol in a frame is used; any duplicates are ignored. Also note that for performance reasons, the entries associated with these symbols are removed from the frame during the main interpreting loop. Your FUNC can return certain values which control continued Regi processing. By default, if your FUNC returns `nil' (as it should be careful to do explicitly), Regi will reset the frame to the first entry, and advance `point' to the beginning of the next line. If a list is returned from your function, it can contain any combination of the following elements: the symbol `continue' This tells Regi to continue processing entries after a match, instead of reseting the frame and moving `point'. In this way, lines of text can have multiple matches, but you have to be careful to avoid entering infinite loops. the symbol `abort' This tells Regi to terminate frame processing. However, any `end' entry is still processed. the list `(frame . NEWFRAME)' This tells Regi to substitute NEWFRAME as the frame it is interpreting. In other words, your FUNC can modify the Regi frame on the fly. NEWFRAME can be a variable containing a frame, or it can be the frame in-lined. the list `(step . STEP)' Tells Regi to move STEP number of lines forward as it continues processing. By default, Regi moves forward one line. STEP can be zero or negative of course, but watch out for infinite loops. During execution of your FUNC, the following variables will be temporarily bound to some useful information: `curline' The current line in the buffer that Regi is `looking-at', as a string. `curframe' The current frame being interpreted. `curentry' The current frame entry being interpreted. File: supercite.info, Node: Frames You Can Customize, Next: Post-yank Formatting Commands, Prev: Using Regi, Up: Configuring the Citation Engine Frames You Can Customize ======================== As mentioned earlier, Supercite uses various frames to perform certain jobs such as mail header information extraction and mail header nuking. However, these frames are not available for you to customize, except through abstract interfaces such as `sc-nuke-mail-header', et al. However, the citation frames Supercite uses provide a lot of customizing power and are thus available to you to change to suit your needs. The workhorse of citation is the frame contained in the variable `sc-default-cite-frame'. This frame recognizes many situations, such as blank lines, which it interprets as paragraph separators. It also recognizes previously cited nested and non-nested citations in the original message. By default it will coerce non-nested citations into your preferred citation style, and it will add a level of citation to nested citations. It will also simply cite uncited lines in your preferred style. In a similar vein, there are default frames for "unciting" and "reciting", contained in the variables `sc-default-uncite-frame' and `sc-default-recite-frame' respectively. As mentioned earlier (*note Recognizing Citations::.), citations are recognized through the values of the regular expressions `sc-citation-root-regexp', et al. To recognize odd styles, you could modify these variables, or you could modify the default citing frame. Alternatively, you could set up association lists of frames for recognizing specific alternative forms. For each of the actions - citing, unciting, and reciting - an alist is consulted to find the frame to use (`sc-cite-frame-alist', `sc-uncite-frame-alist', and `sc-recite-frame-alist' respectively). These frames can contain alists of the form: ((INFOKEY (REGEXP . FRAME) (REGEXP . FRAME) ...) (INFOKEY (REGEXP . FRAME) (REGEXP . FRAME) ...) (...)) Where INFOKEY is a key suitable for `sc-mail-field', REGEXP is a regular expression which is `string-match''d against the value of the `sc-mail-field' key, and FRAME is the frame to use if a match occurred. FRAME can be a variable containing a frame or a frame in-lined. When Supercite is about to cite, uncite, or recite a region, it consults the appropriate alist and attempts to find a frame to use. If one is not found from the alist, then the appropriate default frame is used. File: supercite.info, Node: Post-yank Formatting Commands, Next: Citing Commands, Prev: Frames You Can Customize, Up: Top Post-yank Formatting Commands ***************************** Once the original message has been yanked into the reply buffer, and `sc-cite-original' has had a chance to do its thing, a number of useful Supercite commands will be available to you. Since there is wide variety in the keymaps that MUAs set up in their reply buffers, it is next to impossible for Supercite to properly sprinkle its commands into the existing keymap. For this reason Supercite places its commands on a separate keymap, putting this keymap onto a prefix key in the reply buffer. You can customize the prefix key Supercite uses by changing the variable `sc-mode-map-prefix'. By default, the `sc-mode-map-prefix' is `C-c C-p'; granted, not a great choice, but unfortunately the best general solution so far. In the rest of this chapter, we'll assume you've installed Supercite's keymap on the default prefix. * Menu: * Citing Commands:: * Insertion Commands:: * Variable Toggling Shortcuts:: * Mail Field Commands:: * Miscellaneous Commands:: File: supercite.info, Node: Citing Commands, Next: Insertion Commands, Prev: Post-yank Formatting Commands, Up: Post-yank Formatting Commands Commands to Manually Cite, Recite, and Uncite ============================================= Probably the three most common post-yank formatting operations that you will perform will be the manual citing, reciting, and unciting of regions of text in the reply buffer. Often you may want to recite a paragraph to use a nickname, or manually cite a message when setting `sc-cite-region-limit' to `nil'. The following commands perform these functions on the region of text between `point' and `mark'. Each of them sets the "undo boundary" before modifying the region so that the command can be undone in the standard Emacs way. A quick note about Emacs 19. Unlike in Emacs 18, the region delimited by `point' and `mark' can have two states. It can be "active" or "inactive". Although the FSF Emacs 19 and Lucid Emacs 19 use different terminology and functions, both employ the same convention such that when the region is inactive, commands that modify the region should generate an error. The user needs to explicitly activate the region before successfully executing the command. All Supercite commands conform to this convention. Here is the list of Supercite citing commands: `sc-cite-region' (`C-c C-p c') This command cites each line in the region of text by interpreting the selected frame from `sc-cite-frame-alist', or the default citing frame `sc-default-cite-frame'. It runs the hook `sc-pre-cite-hook' before interpreting the frame. With an optional universal argument (`C-u'), it temporarily sets `sc-confirm-always-p' to `t' so you can confirm the attribution string for a single manual citing. *Note Configuring the Citation Engine::. `sc-uncite-region' (`C-c C-p u') This command removes any citation strings from the beginning of each cited line in the region by interpreting the selected frame from `sc-uncite-frame-alist', or the default unciting frame `sc-default-uncite-frame'. It runs the hook `sc-pre-uncite-hook' before interpreting the frame. *Note Configuring the Citation Engine::. `sc-recite-region' (`C-c C-p r') This command recites each line the region by interpreting the selected frame from `sc-recite-frame-alist', or the default reciting frame `sc-default-recite-frame'. It runs the hook `sc-pre-recite-hook' before interpreting the frame. *Note Configuring the Citation Engine::. Supercite will always ask you to confirm the attribution when reciting a region, regardless of the value of `sc-confirm-always-p'. File: supercite.info, Node: Insertion Commands, Next: Variable Toggling Shortcuts, Prev: Citing Commands, Up: Post-yank Formatting Commands Insertion Commands ================== These two functions insert various strings into the reply buffer. `sc-insert-reference' (`C-c C-p w') Inserts a reference header into the reply buffer at `point'. With no arguments, the header indexed by `sc-preferred-header-style' is inserted. An optional numeric argument is the index into `sc-rewrite-header-list' indicating which reference header to write. With just the universal argument (`C-u'), electric reference mode is entered, regardless of the value of `sc-electric-references-p'. `sc-insert-citation' (`C-c C-p i') Inserts the current citation string at the beginning of the line that `point' is on. If the line is already cited, Supercite will issue an error and will not cite the line. File: supercite.info, Node: Variable Toggling Shortcuts, Next: Mail Field Commands, Prev: Insertion Commands, Up: Post-yank Formatting Commands Variable Toggling Shortcuts =========================== Supercite defines a number of commands that make it easier for you to toggle and set various Supercite variables as you are editing the reply buffer. For example, you may want to turn off filling or whitespace cleanup, but only temporarily. These toggling shortcut commands make this easy to do. Like Supercite commands in general, the toggling commands are placed on a keymap prefix within the greater Supercite keymap. For the default value of `sc-mode-map-prefix', this will be `C-c C-p C-t'. The following commands toggle the value of certain Supercite variables which take only a binary value: `C-c C-p C-t b' Toggles the variable `sc-mail-nuke-blank-lines-p'. `C-c C-p C-t c' Toggles the variable `sc-confirm-always-p'. `C-c C-p C-t d' Toggles the variable `sc-downcase-p'. `C-c C-p C-t e' Toggles the variable `sc-electric-references-p'. `C-c C-p C-t f' Toggles the variable `sc-auto-fill-region-p'. `C-c C-p C-t o' Toggles the variable `sc-electric-circular-p'. `C-c C-p C-t s' Toggles the variable `sc-nested-citation-p'. `C-c C-p C-t u' Toggles the variable `sc-use-only-preferences-p'. `C-c C-p C-t w' Toggles the variable `sc-fixup-whitespace-p'. The following commands let you set the value of multi-value variables, in the same way that Emacs' `set-variable' does: `C-c C-p C-t a' Sets the value of the variable `sc-preferred-attribution-list'. `C-c C-p C-t l' Sets the value of the variable `sc-cite-region-limit'. `C-c C-p C-t n' Sets the value of the variable `sc-mail-nuke-mail-headers'. `C-c C-p C-t N' Sets the value of the variable `sc-mail-header-nuke-list'. `C-c C-p C-t p' Sets the value of the variable `sc-preferred-header-style'. One special command is provided to toggle both `sc-auto-fill-region-p' and `sc-fixup-whitespace-p' together. This is because you typically want to run Supercite with either variable as `nil' or non-`nil'. The command to toggle these variables together is bound on `C-c C-p C-p'. Finally, the command `C-c C-p C-t h' (also `C-c C-p C-t ?') brings up a Help message on the toggling keymap. File: supercite.info, Node: Mail Field Commands, Next: Miscellaneous Commands, Prev: Variable Toggling Shortcuts, Up: Post-yank Formatting Commands Mail Field Commands =================== These commands allow you to view, modify, add, and delete various bits of information from the info alist. *Note Information Keys and the Info Alist::. `sc-mail-field-query' (`C-c C-p f') Allows you to interactively view, modify, add, and delete info alist key-value pairs. With no argument, you are prompted (with completion) for a info key. The value associated with that key is displayed in the minibuffer. With an argument, this command will first ask if you want to view, modify, add, or delete an info key. Viewing is identical to running the command with no arguments. If you want to modify the value of a key, Supercite will first prompt you (with completion) for the key of the value you want to change. It will then put you in the minibuffer with the key's current value so you can edit the value as you wish. When you hit RET, the key's value is changed. For those of you running Emacs 19, minibuffer history is kept for the values. If you choose to delete a key-value pair, Supercite will prompt you (with completion) for the key to delete. If you choose to add a new key-value pair, Supercite firsts prompts you for the key to add. Note that completion is turned on for this prompt, but you can type any key name here, even one that does not yet exist. After entering the key, Supercite prompts you for the key's value. It is not an error to enter a key that already exists, but the new value will override any old value. It will not replace it though; if you subsequently delete the key-value pair, the old value will reappear. `sc-mail-process-headers' (`C-c C-p g') This command lets you re-initialize Supercite's info alist from any set of mail headers in the region between `point' and `mark'. This function is especially useful for replying to digest messages where Supercite will initially set up its information for the digest originator, but you want to cite each component article with the real message author. Note that unless an error during processing occurs, any old information is lost. File: supercite.info, Node: Miscellaneous Commands, Next: Information Keys and the Info Alist, Prev: Mail Field Commands, Up: Post-yank Formatting Commands Miscellaneous Commands ====================== `sc-open-line' (`C-c C-p o') Similar to Emacs' standard `open-line' commands, but inserts the citation string in front of the new line. As with `open-line', an optional numeric argument inserts that many new lines. `sc-describe' (`C-c C-p h' and `C-c C-p ?') This function has been obsoleted by the TeXinfo manual you are now reading. It is still provided for compatibility, but it will eventually go away. `sc-version' (`C-c C-p v') Echos the version of Supercite you are using. With the optional universal argument (`C-u'), this command inserts the version information into the current buffer. `sc-submit-bug-report' (`C-c C-p C-b') If you encounter a bug, or wish to suggest an enhancement, use this command to set up an outgoing mail buffer, with the proper address to the Supercite maintainer automatically inserted in the `To:' field. This command also inserts information that the Supercite maintainer can use to recreate your exact setup, making it easier to verify your bug. File: supercite.info, Node: Hints to MUA Authors, Next: Version 3 Changes, Prev: Electric References, Up: Top Hints to MUA Authors ******************** In June of 1989, some discussion was held between the various MUA authors, the Supercite author, and other Supercite users. These discussions centered around the need for a standard interface between MUAs and Supercite (or any future Supercite-like packages). This interface was formally proposed by Martin Neitzel on Fri, 23 Jun 89, in a mail message to the Supercite mailing list: Martin> Each news/mail-reader should provide a form of Martin> mail-yank-original that Martin> 1: inserts the original message incl. header into the Martin> reply buffer; no indentation/prefixing is done, the header Martin> tends to be a "full blown" version rather than to be Martin> stripped down. Martin> 2: `point' is at the start of the header, `mark' at the Martin> end of the message body. Martin> 3: (run-hooks 'mail-yank-hooks) Martin> [Supercite] should be run as such a hook and merely Martin> rewrite the message. This way it isn't anymore Martin> [Supercite]'s job to gather the original from obscure Martin> sources. [...] This specification was adopted, but with the recent release of FSF GNU Emacs 19, it has undergone a slight modification. Instead of the variable `mail-yank-hooks', the new preferred hook variable that the MUA should provide is `mail-citation-hook'. `mail-yank-hooks' can be provided for backward compatibility, but `mail-citation-hook' should always take precedence. Richard Stallman (of the FSF) suggests that the MUAs should `defvar' `mail-citation-hook' to `nil' and perform some default citing when that is the case. Take a look at Emacs 19's `sendmail.el' file, specifically the `mail-yank-original' defun for details. If you are writing a new MUA package, or maintaining an existing MUA package, you should make it conform to this interface so that your users will be able to link Supercite easily and seamlessly. To do this, when setting up a reply or forward buffer, your MUA should follow these steps: 1. Insert the original message, including the mail headers into the reply buffer. At this point you should not modify the raw text in any way, and you should place all the original headers into the body of the reply. This means that many of the mail headers will be duplicated, one copy above the `mail-header-separator' line and one copy below, however there will probably be more headers below this line. 2. Set `point' to the beginning of the line containing the first mail header in the body of the reply. Set `mark' at the end of the message text. It is very important that the region be set around the text Supercite is to modify and that the mail headers are within this region. Supercite will not venture outside the region for any reason, and anything within the region is fair game, so don't put anything that *must* remain unchanged inside the region. Further note that for Emacs 19, the region need not be set active. Supercite will work properly when the region is inactive, as should any other like-minded package. 3. Run the hook `mail-citation-hook'. You will probably want to provide some kind of default citation functions in cases where the user does not have Supercite installed. By default, your MUA should `defvar' `mail-citation-hook' to `nil', and in your yanking function, check its value. If it finds `mail-citation-hook' to be `nil', it should perform some default citing behavior. User who want to connect to Supercite then need only add `sc-cite-original' to this list of hooks using `add-hook'. If you do all this, your users will not need to overload your routines to use Supercite, and your MUA will join the ranks of those that conform to this interface "out of the box." File: supercite.info, Node: Version 3 Changes, Next: Thanks and History, Prev: Hints to MUA Authors, Up: Top Version 3 Changes ***************** With version 3, Supercite has undergone an almost complete rewrite, and has hopefully benefitted in a number of ways, including vast improvements in the speed of performance, a big reduction in size of the code and in the use of Emacs resources, and a much cleaner and flexible internal architecture. The central construct of the info alist, and its role in Supercite has been expanded, and the other central concept, the general package Regi, was developed to provide a theoretically unlimited flexibility. But most of this work is internal and not of very great importance to the casual user. There have been some changes at the user-visible level, but for the most part, the Supercite configuration variables from version 2 should still be relevant to version 3. Below, I briefly outline those user-visible things that have changed since version 2. For details, look to other sections of this manual. 1. Supercite proper now comes in a single file, `supercite.el', which contains everything except the unsupported noodlings, overloading (which should be more or less obsolete with the release of Emacs 19), and the general lisp packages `reporter.el' and `regi.el'. Finally, the TeXinfo manual comes in its own file as well. In particular, the file `sc.el' from the version 2 distribution is obsolete, as is the file `sc-elec.el'. 2. `sc-spacify-name-chars' is gone in version 3. 3. `sc-nickname-alist' is gone in version 3. The `sc-attrib-selection-list' is a more general construct supporting the same basic feature. 4. The version 2 variable `sc-preferred-attribution' has been changed to `sc-preferred-attribution-list', and has been expanded upon to allow you to specify an ordered list of preferred attributions. 5. `sc-mail-fields-list' has been removed, and header nuking in general has been greatly improved, giving you wider flexibility in specifying which headers to keep and remove while presenting a simplified interface to commonly chosen defaults. 6. Post-yank paragraph filling has been completely removed from Supercite, other packages just do it better than Supercite ever would. Supercite will still fill newly cited paragraphs. 7. The variable `sc-all-but-cite-p' has been replaced by `sc-cite-region-limit'. 8. Keymap hacking in the reply buffer has been greatly simplified, with, I believe, little reduction in functionality. 9. Hacking of the reply buffer's docstring has been completely eliminated. File: supercite.info, Node: Thanks and History, Next: The Supercite Mailing List, Prev: Version 3 Changes, Up: Top Thanks and History ****************** The Supercite package was derived from its predecessor Superyank 1.11 which was inspired by various bits of code and ideas from Martin Neitzel and Ashwin Ram. They were the folks who came up with the idea of non-nested citations and implemented some rough code to provide this style. Superyank and Supercite version 2 evolved to the point where much of the attribution selection mechanism was automatic, and features have been continuously added through the comments and suggestions of the Supercite mailing list participants. Supercite version 3 represents a nearly complete rewrite with many of the algorithms and coding styles being vastly improved. Hopefully Supercite version 3 is faster, smaller, and much more flexible than its predecessors. In the version 2 manual I thanked some specific people for their help in developing Supercite 2. You folks know who you are and your continued support is greatly appreciated. I wish to thank everyone on the Supercite mailing list, especially the brave alpha testers, who helped considerably in testing out the concepts and implementation of Supercite version 3. Special thanks go out to the MUA and Emacs authors Kyle Jones, Stephen Gildea, Richard Stallman, and Jamie Zawinski for coming to a quick agreement on the new `mail-citation-hook' interface, and for adding the magic lisp to their code to support this. All who have helped and contributed have been greatly appreciated.
