The GNU Translation Project is a way to +get maintainers, translators, and users all together, so that GNU will +gradually become able to speak many languages. A few packages already +provide translations for their messages. + + If you found this `ABOUT-NLS' file inside a GNU distribution, you +may assume that the distributed package does use GNU `gettext' +internally, itself available at your nearest GNU archive site. But you +do *not* need to install GNU `gettext' prior to configuring, installing +or using this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work at translations should contact the appropriate team. + + When reporting bugs in the `intl/' directory or bugs which may be +related to internationalization, you should tell about the version of +`gettext' which is used. The information can be found in the +`intl/VERSION' file, in internationalized packages. + +One advise in advance +===================== + + If you want to exploit the full power of internationalization, you +should configure it using + + ./configure --with-included-gettext + +to force usage of internationalizing routines provided within this +package, despite the existence of internationalizing capabilities in +the operating system where this package is being installed. So far, no +prior implementation provides as many useful features (such as locale +alias or message inheritance). It is also not possible to offer this +additional functionality on top of a `catgets' implementation. Future +versions of GNU `gettext' will very likely convey even more +functionality. So it might be a good idea to change to GNU `gettext' +as soon as possible. + +INSTALL Matters +=============== + + Some GNU packages are "localizable" when properly installed; the +programs they contain can be made to speak your own native language. +Most such packages use GNU `gettext'. Other packages have their own +ways to internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system provides +usable `catgets' (if using this is selected by the installer) or +`gettext' functions. If neither is available, the GNU `gettext' own +library will be used. This library is wholly contained within this +package, usually in the `intl/' subdirectory, so prior installation of +the GNU `gettext' package is *not* required. Installers may use +special options at configuration time for changing the default +behaviour. The commands: + + ./configure --with-included-gettext + ./configure --with-catgets + ./configure --disable-nls + +will respectively bypass any pre-existing `catgets' or `gettext' to use +the internationalizing routines provided within this package, enable +the use of the `catgets' functions (if found on the locale system), or +else, *totally* disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl.a' file and +will decide to use this. This might be not what is desirable. You +should use the more recent version of the GNU `gettext' library. I.e. +if the file `intl/VERSION' shows that the library which comes with this +package is more recent, you should use + + ./configure --with-included-gettext + +to prevent auto-detection. + + By default the configuration process will not test for the `catgets' +function and therefore they will not be used. The reasons are already +given above: the emulation on top of `catgets' cannot provide all the +extensions provided by the GNU `gettext' library. If you nevertheless +want to use the `catgets' functions use + + ./configure --with-catgets + +to enable the test for `catgets' (this causes no harm if `catgets' is +not available on your system). If you really select this option we +would like to hear about the reasons because we cannot think of any +good one ourself. + + Internationalized packages have usually many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +Using This Package +================== + + As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +ISO 639 `LL' two-letter code prior to using the programs in the +package. For example, let's suppose that you speak German. At the +shell prompt, merely execute `setenv LANG de' (in `csh'), +`export LANG; LANG=de' (in `sh') or `export LANG=de' (in `bash'). This +can be done from your `.login' or `.profile' file, once and for all. + + An operating system might already offer message localization for +many of its programs, while other programs (whether GNU or not) have +been installed locally with the full capabilities of GNU `gettext'. +Just using `gettext' extended syntax for `LANG' would break proper +localization of already available operating system programs. In this +case, users should set both `LANGUAGE' and `LANG' variables in their +environment, as programs using GNU `gettext' give preference to +`LANGUAGE'. For example, some Swedish users would rather read +translations in German than English for when Swedish is not available. +This is easily accomplished by setting `LANGUAGE' to `sv:de' while +leaving `LANG' to `sv'. + +Translating Teams +================= + + For the GNU Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list, courtesy of Linux +International. You may reach your translation team at the address +`LL@li.org', replacing LL by the two-letter ISO 639 code for your +language. Language codes are *not* the same as the country codes given +in ISO 3166. The following translation teams exist, as of February +1997: + + Arabic `ar', Chinese `zh', Czech `cs', Danish `da', Dutch `nl', + English `en', Esperanto `eo', Finnish `fi', French `fr', German + `de', Greek `el', Hebrew `he', Hungarian `hu', Irish `ga', Italian + `it', Indonesian `id', Japanese `ja', Korean `ko', Latin `la', + Norwegian `no', Persian `fa', Polish `pl', Portuguese `pt', + Russian `ru', Slovenian `sl', Spanish `es', Swedish `sv', Telugu + `te', Turkish `tr' and Ukrainian `uk'. + +For example, you may reach the Chinese translation team by writing to +`zh@li.org'. + + If you'd like to volunteer to *work* at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is *not* the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +*actively* in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `gnu-translation@gnu.ai.mit.edu' to reach +the GNU coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology used in GNU. Proven linguistic skill are praised more +than programming skill, here. For the time being, please avoid +subscribing to the English team unless explicitly invited to do so. + +Available Packages +================== + + Languages are not equally supported in all GNU packages.

This means that the menu item: + +* Info:: The Info documentation reader. + +in (dir) refers to the info node "(info)Top". + +Please see the ChangeLog and documentation for details on other +changes. + +Version 2.7 beta, Wed Dec 30 02:02:38 1992 +Version 2.6 beta, Tue Dec 22 03:58:07 1992 +Version 2.5 beta, Tue Dec 8 14:50:35 1992 +Version 2.4 beta, Sat Nov 28 14:34:02 1992 +Version 2.3 beta, Fri Nov 27 01:04:13 1992 +Version 2.2 beta, Tue Nov 24 09:36:08 1992 +Version 2.1 beta, Tue Nov 17 23:29:36 1992 + +Changes since 2.5 beta: + +Note that versions 2.6 and 2.7 Beta were only released to a select group. + +* "info-" removed from the front of M-x commands. + +* Automatic footnote display. When you enter a node which contains + footnotes, and the variable "automatic-footnotes" is "On", Info pops + up a window containing the footnotes. Likewise, when you leave that + node, the window containing the footnotes goes away. + +* Cleaner built in documentation, and documentation functions. + + Use: + o `M-x describe-variable' to read a variable's documenation + o `M-x describe-key' to find out what a particular keystroke does. + o `M-x describe-function' to read a function's documentation. + o `M-x where-is' to find out what keys invoke a particular function. + +* Info can "tile" the displayed windows (via "M-x tile-windows"). If + the variable "automatic-tiling" is "On", then splitting a window or + deleting a window causes the remaining windows to be retiled. + +* You can save every keystroke you type in a "dribble file" by using the + `--dribble FILENAME' option. You can initially read keystrokes from an + alternate input stream with `--restore FILENAME', or by redirecting + input on the command line `info < old-dribble'. + +* New behaviour of menu items. If the label is the same as the + target node name, and the node couldn't be found in the current file, + treat the label as a file name. For example, a menu entry in "DIR" + might contain: + + * Emacs:: Cool text-editor. + + Info would not find the node "(dir)Emacs", so just plain "(emacs)" + would be tried. + +* New variable "ISO-Latin" allows you to use European machines with + 8-bit character sets. + +* Cleanups in echo area reading, and redisplay. Cleanups in handling the + window which shows possible completions. + +* Info can now read files that have been compressed. An array in filesys.c + maps extensions to programs that can decompress stdin, and write the results + to stdout. Currently, ".Z"/uncompress, ".z"/gunzip, and ".Y"/unyabba are + supported. The modeline for a compressed file shows "zz" in it. + +* There is a new variable "gc-compressed-files" which, if non-zero, says + it is okay to reclaim the file buffer space allocated to a file which + was compressed, if, and only if, that file's contents do not appear in + any history node. + +* New file `nodemenu.c' implements a few functions for manipulating + previously visited nodes. `C-x C-b' (list-visited-nodes) produces a + menu of the nodes that could be reached by info-history-node in some + window. `C-x b' (select-visited-node) is similar, but reads one of + the node names with completion. + +* Keystroke `M-r' (move_to_screen_line) allows the user to place the cursor at + the start of a specific screen line. Without a numeric argument, place the + cursor on the center line; with an arg, place the cursor on that line. + +* Interruptible display implemented. Basic display speedups and hacks. +* The message "*** Tags Out of Date ***" now means what it says. +* Index searching with `,' (info-index-next) has been improved. +* When scrolling with C-v, C-M-v, or M-v, only "Page Only" scrolling + will happen. + +* Continous scrolling (along with `]' (info-global-next) and `[' + (info-global-prev) works better. `]' and `[' accept numeric + arguments, moving that many nodes in that case. + +* `C-x w' (info-toggle-wrap) controls how lines wider than the width + of the screen are displayed. If a line is too long, a `$' is + displayed in the rightmost column of the window. + +* There are some new variables for controlling the behaviour of Info + interactively. The current list of variables is as follows: + + Variable Name Default Value Description + ------------- ------------- ----------- + `automatic-footnotes' On When "On", footnotes appear and + disappear automatically. + + `automatic-tiling' Off When "On", creating of deleting a + window resizes other windows. + + `visible-bell' Off If non-zero, try to use a visible bell. + + `errors-ring-bell' On If non-zero, errors cause a ring. + + `show-index-match' On If non-zero, the portion of the string + matched is highlighted by changing its + case. + + `scroll-behaviour' Continuous One of "Continuous", "Next Only", or + "Page Only". "Page Only" prevents you from + scrolling past the bottom or top of a node. + "Next Only" causes the Next or Prev node to + be selected when you scroll past the bottom + or top of a node. "Continous" moves + linearly through the files hierchichal + structure. + + `scroll-step' 0 Controls how scrolling is done for you when + the cursor moves out of the current window. + Non-zero means it is the number of lines + you would like the screen to shift. A + value of 0 means to center the line + containing the cursor in the window. + + `gc-compressed-files' Off If non-zero means it is okay to reclaim the + file buffer space allocated to a file which + was compressed, if, and only if, that + file's contents do not appear in the node + list of any window. + + `ISO-Latin' Off Non-zero means that you are using an ISO + Latin character set. By default, standard + ASCII characters are assumed. +________________________________________ +This release of Info is version 2.5 beta. + +Changes since 2.4 beta: + +* Index (i) and (,) commands fully implemented. +* "configure" script now shipped with Info. +* New function "set-variable" allows users to set various variables. +* User-settable behaviour on end or beginning of node scrolling.

When a node is selected, a +window containing the footnotes which appear in that node is created, +and the footnotes are displayed within the new window. The window that +Info creates to contain the footnotes is called @samp{*Footnotes*}. If +a node is selected which contains no footnotes, and a @samp{*Footnotes*} +window is on the screen, the @samp{*Footnotes*} window is deleted. +Footnote windows created in this fashion are not automatically tiled so +that they can use as little of the display as is possible. + +@item automatic-tiling +@vindex automatic-tiling +When set to @code{On}, creating or deleting a window resizes other +windows. This variable is @code{Off} by default. Normally, typing +@samp{C-x 2} divides the current window into two equal parts. When +@code{automatic-tiling} is set to @code{On}, all of the windows are +resized automatically, keeping an equal number of lines visible in each +window. There are exceptions to the automatic tiling; specifically, the +windows @samp{*Completions*} and @samp{*Footnotes*} are @emph{not} +resized through automatic tiling; they remain their original size. + +@item visible-bell +@vindex visible-bell +When set to @code{On}, GNU Info attempts to flash the screen instead of +ringing the bell. This variable is @code{Off} by default. Of course, +Info can only flash the screen if the terminal allows it; in the case +that the terminal does not allow it, the setting of this variable has no +effect. However, you can make Info perform quietly by setting the +@code{errors-ring-bell} variable to @code{Off}. + +@item errors-ring-bell +@vindex errors-ring-bell +When set to @code{On}, errors cause the bell to ring. The default +setting of this variable is @code{On}. + +@item gc-compressed-files +@vindex gc-compressed-files +When set to @code{On}, Info garbage collects files which had to be +uncompressed. The default value of this variable is @code{Off}. +Whenever a node is visited in Info, the Info file containing that node +is read into core, and Info reads information about the tags and nodes +contained in that file. Once the tags information is read by Info, it +is never forgotten. However, the actual text of the nodes does not need +to remain in core unless a particular Info window needs it. For +non-compressed files, the text of the nodes does not remain in core when +it is no longer in use. But de-compressing a file can be a time +consuming operation, and so Info tries hard not to do it twice. +@code{gc-compressed-files} tells Info it is okay to garbage collect the +text of the nodes of a file which was compressed on disk. + +@item show-index-match +@vindex show-index-match +When set to @code{On}, the portion of the matched search string is +highlighted in the message which explains where the matched search +string was found. The default value of this variable is @code{On}. +When Info displays the location where an index match was found, +(@pxref{Searching Commands, , @code{next-index-match}}), the portion of the +string that you had typed is highlighted by displaying it in the inverse +case from its surrounding characters. + +@item scroll-behavior +@vindex scroll-behavior +Control what happens when forward scrolling is requested at the end of +a node, or when backward scrolling is requested at the beginning of a +node. The default value for this variable is @code{Continuous}. There +are three possible values for this variable: + +@table @code +@item Continuous +Try to get the first item in this node's menu, or failing that, the +@samp{Next} node, or failing that, the @samp{Next} of the @samp{Up}. +This behavior is identical to using the @samp{]} +(@code{global-next-node}) and @samp{[} (@code{global-prev-node}) +commands. + +@item Next Only +Only try to get the @samp{Next} node. + +@item Page Only +Simply give up, changing nothing. If @code{scroll-behavior} is +@code{Page Only}, no scrolling command can change the node that is being +viewed. +@end table + +@item scroll-step +@vindex scroll-step +The number of lines to scroll when the cursor moves out of the window. +Scrolling happens automatically if the cursor has moved out of the +visible portion of the node text when it is time to display. Usually +the scrolling is done so as to put the cursor on the center line of the +current window. However, if the variable @code{scroll-step} has a +nonzero value, Info attempts to scroll the node text by that many lines; +if that is enough to bring the cursor back into the window, that is what +is done. The default value of this variable is 0, thus placing the +cursor (and the text it is attached to) in the center of the window. +Setting this variable to 1 causes a kind of "smooth scrolling" which +some people prefer. + +@item ISO-Latin +@cindex ISO Latin characters +@vindex ISO-Latin +When set to @code{On}, Info accepts and displays ISO Latin characters. +By default, Info assumes an ASCII character set. @code{ISO-Latin} tells +Info that it is running in an environment where the European standard +character set is in use, and allows you to input such characters to +Info, as well as display them. +@end table + + + +@c the following is incomplete +@ignore +@c node Info for Sys Admins +@c chapter Info for System Administrators + +This text describes some common ways of setting up an Info hierarchy +from scratch, and details the various options that are available when +installing Info.

Menus allow a branching +structure. A menu is a list of other nodes you can move to. It is +actually just part of the text of the node formatted specially so that +Info can interpret it. The beginning of a menu is always identified +by a line which starts with @samp{* Menu:}. A node contains a menu if and +only if it has a line in it which starts that way. The only menu you +can use at any moment is the one in the node you are in. To use a +menu in any other node, you must move to that node first. + + After the start of the menu, each line that starts with a @samp{*} +identifies one subtopic. The line usually contains a brief name +for the subtopic (followed by a @samp{:}), the name of the node that talks +about that subtopic, and optionally some further description of the +subtopic. Lines in the menu that do not start with a @samp{*} have no +special meaning---they are only for the human reader's benefit and do +not define additional subtopics. Here is an example: + +@example +* Foo: FOO's Node This tells about FOO +@end example + +The subtopic name is Foo, and the node describing it is @samp{FOO's Node}. +The rest of the line is just for the reader's Information. +[[ But this line is not a real menu item, simply because there is +no line above it which starts with @samp{* Menu:}.]] + + When you use a menu to go to another node (in a way that will be +described soon), what you specify is the subtopic name, the first +thing in the menu line. Info uses it to find the menu line, extracts +the node name from it, and goes to that node. The reason that there +is both a subtopic name and a node name is that the node name must be +meaningful to the computer and may therefore have to be ugly looking. +The subtopic name can be chosen just to be convenient for the user to +specify. Often the node name is convenient for the user to specify +and so both it and the subtopic name are the same. There is an +abbreviation for this: + +@example +* Foo:: This tells about FOO +@end example + +@noindent +This means that the subtopic name and node name are the same; they are +both @samp{Foo}. + +>> Now use Spaces to find the menu in this node, then come back to + the front with a @kbd{b} and some Spaces. As you see, a menu is + actually visible in its node. If you cannot find a menu in a node + by looking at it, then the node does not have a menu and the + @kbd{m} command is not available. + + The command to go to one of the subnodes is @kbd{m}---but @emph{do +not do it yet!} Before you use @kbd{m}, you must understand the +difference between commands and arguments. So far, you have learned +several commands that do not need arguments. When you type one, Info +processes it and is instantly ready for another command. The @kbd{m} +command is different: it is incomplete without the @dfn{name of the +subtopic}. Once you have typed @kbd{m}, Info tries to read the +subtopic name. + + Now look for the line containing many dashes near the bottom of the +screen. There is one more line beneath that one, but usually it is +blank. If it is empty, Info is ready for a command, such as @kbd{n} +or @kbd{b} or Space or @kbd{m}. If that line contains text ending +in a colon, it mean Info is trying to read the @dfn{argument} to a +command. At such times, commands do not work, because Info tries to +use them as the argument. You must either type the argument and +finish the command you started, or type @kbd{Control-g} to cancel the +command. When you have done one of those things, the line becomes +blank again. + + The command to go to a subnode via a menu is @kbd{m}. After you type +the @kbd{m}, the line at the bottom of the screen says @samp{Menu item: }. +You must then type the name of the subtopic you want, and end it with +a @key{RET}. + + You can abbreviate the subtopic name. If the abbreviation is not +unique, the first matching subtopic is chosen. Some menus put +the shortest possible abbreviation for each subtopic name in capital +letters, so you can see how much you need to type. It does not +matter whether you use upper case or lower case when you type the +subtopic. You should not put any spaces at the end, or inside of the +item name, except for one space where a space appears in the item in +the menu. + + You can also use the @dfn{completion} feature to help enter the subtopic +name. If you type the Tab key after entering part of a name, it will +magically fill in more of the name---as much as follows uniquely from +what you have entered. + + If you move the cursor to one of the menu subtopic lines, then you do +not need to type the argument: you just type a Return, and it stands for +the subtopic of the line you are on. + +Here is a menu to give you a chance to practice. + +* Menu: The menu starts here. + +This menu gives you three ways of going to one place, Help-FOO. + +* Foo: Help-FOO.

Thus, @kbd{gTop@key{RET}} would go to the node +called @samp{Top} in this file (its directory node). +@kbd{gExpert@key{RET}} would come back here. + +Unlike @kbd{m}, @kbd{g} does not allow the use of abbreviations. + +To go to a node in another file, you can include the filename in the +node name by putting it at the front, in parentheses. Thus, +@kbd{g(dir)Top@key{RET}} would go to the Info Directory node, which is +node @samp{Top} in the file @file{dir}. + +The node name @samp{*} specifies the whole file. So you can look at +all of the current file by typing @kbd{g*@key{RET}} or all of any +other file with @kbd{g(FILENAME)@key{RET}}. + +The @kbd{s} command allows you to search a whole file for a string. +It switches to the next node if and when that is necessary. You +type @kbd{s} followed by the string to search for, terminated by +@key{RET}. To search for the same string again, just @kbd{s} followed +by @key{RET} will do. The file's nodes are scanned in the order +they are in in the file, which has no necessary relationship to the +order that they may be in in the tree structure of menus and @samp{next} pointers. +But normally the two orders are not very different. In any case, +you can always do a @kbd{b} to find out what node you have reached, if +the header is not visible (this can happen, because @kbd{s} puts your +cursor at the occurrence of the string, not at the beginning of the +node). + +If you grudge the system each character of type-in it requires, you +might like to use the commands @kbd{1}, @kbd{2}, @kbd{3}, @kbd{4}, ... +@kbd{9}. They are short for the @kbd{m} command together with an +argument. @kbd{1} goes through the first item in the current node's +menu; @kbd{2} goes through the second item, etc. + +If you display supports multiple fonts, and you are using Emacs' Info +mode to read Info files, the @samp{*} for the fifth menu item is +underlines, and so is the @samp{*} for the ninth item; these underlines +make it easy to see at a glance which number to use for an item. + +On ordinary terminals, you won't have underlining. If you need to +actually count items, it is better to use @kbd{m} instead, and specify +the name. + +The Info command @kbd{e} changes from Info mode to an ordinary +Emacs editing mode, so that you can edit the text of the current node. +Type @kbd{C-c C-c} to switch back to Info. The @kbd{e} command is allowed +only if the variable @code{Info-enable-edit} is non-@code{nil}. + +@node Add, Menus, Expert, Advanced Info +@comment node-name, next, previous, up +@section Adding a new node to Info + +To add a new topic to the list in the Info directory, you must: +@enumerate +@item +Create some nodes, in some file, to document that topic. +@item +Put that topic in the menu in the directory. @xref{Menus, Menu}. +@end enumerate + +Usually, the way to create the nodes is with Texinfo @pxref{Top,, Overview of +Texinfo, texinfo, Texinfo: The GNU Documentation Format}); this has the +advantage that you can also make a printed manual from them. However, +if hyou want to edit an Info file, here is how. + + The new node can live in an existing documentation file, or in a new +one. It must have a @key{^_} character before it (invisible to the +user; this node has one but you cannot see it), and it ends with either +a @key{^_}, a @key{^L}, or the end of file. Note: If you put in a +@key{^L} to end a new node, be sure that there is a @key{^_} after it +to start the next one, since @key{^L} cannot @emph{start} a node. +Also, a nicer way to make a node boundary be a page boundary as well +is to put a @key{^L} @emph{right after} the @key{^_}. + + The @key{^_} starting a node must be followed by a newline or a +@key{^L} newline, after which comes the node's header line. The +header line must give the node's name (by which Info finds it), +and state the names of the @samp{Next}, @samp{Previous}, and @samp{Up} nodes (if +there are any). As you can see, this node's @samp{Up} node is the node +@samp{Top}, which points at all the documentation for Info. The @samp{Next} +node is @samp{Menus}. + + The keywords @dfn{Node}, @dfn{Previous}, @dfn{Up}, and @dfn{Next}, +may appear in any order, anywhere in the header line, but the +recommended order is the one in this sentence. Each keyword must be +followed by a colon, spaces and tabs, and then the appropriate name. +The name may be terminated with a tab, a comma, or a newline. A space +does not end it; node names may contain spaces. The case of letters +in the names is insignificant. + + A node name has two forms. A node in the current file is named by +what appears after the @samp{Node: } in that node's first line. For +example, this node's name is @samp{Add}. A node in another file is +named by @samp{(@var{filename})@var{node-within-file}}, as in +@samp{(info)Add} for this node. If the file name starts with ``./'', +then it is relative to the current directory; otherwise, it is relative +starting from the standard Info file directory of your site. +The name @samp{(@var{filename})Top} can be abbreviated to just +@samp{(@var{filename})}. By convention, the name @samp{Top} is used for +the ``highest'' node in any single file---the node whose @samp{Up} points +out of the file. The Directory node is @file{(dir)}. The @samp{Top} node +of a document file listed in the Directory should have an @samp{Up: +(dir)} in it. + + The node name @kbd{*} is special: it refers to the entire file. +Thus, @kbd{g*} shows you the whole current file. The use of the +node @kbd{*} is to make it possible to make old-fashioned, +unstructured files into nodes of the tree. + + The @samp{Node:} name, in which a node states its own name, must not +contain a filename, since Info when searching for a node does not +expect one to be there. The @samp{Next}, @samp{Previous} and @samp{Up} names may +contain them. In this node, since the @samp{Up} node is in the same file, +it was not necessary to use one. + + Note that the nodes in this file have a file name in the header +line. The file names are ignored by Info, but they serve as comments +to help identify the node for the user. + +@node Menus, Cross-refs, Add, Advanced Info +@comment node-name, next, previous, up +@section How to Create Menus + + Any node in the Info hierarchy may have a @dfn{menu}---a list of subnodes. +The @kbd{m} command searches the current node's menu for the topic which it +reads from the terminal. + + A menu begins with a line starting with @samp{* Menu:}. The rest of the +line is a comment. After the starting line, every line that begins +with a @samp{* } lists a single topic. The name of the topic--the +argument that the user must give to the @kbd{m} command to select this +topic---comes right after the star and space, and is followed by a +colon, spaces and tabs, and the name of the node which discusses that +topic. The node name, like node names following @samp{Next}, @samp{Previous} +and @samp{Up}, may be terminated with a tab, comma, or newline; it may also +be terminated with a period. + + If the node name and topic name are the same, then rather than +giving the name twice, the abbreviation @samp{* NAME::} may be used +(and should be used, whenever possible, as it reduces the visual +clutter in the menu). + + It is considerate to choose the topic names so that they differ +from each other very near the beginning---this allows the user to type +short abbreviations. In a long menu, it is a good idea to capitalize +the beginning of each item name which is the minimum acceptable +abbreviation for it (a long menu is more than 5 or so entries). + + The nodes listed in a node's menu are called its ``subnodes'', and +it is their ``superior''. They should each have an @samp{Up:} pointing at +the superior. It is often useful to arrange all or most of the +subnodes in a sequence of @samp{Next} and @samp{Previous} pointers so that someone who +wants to see them all need not keep revisiting the Menu. + + The Info Directory is simply the menu of the node @samp{(dir)Top}---that +is, node @samp{Top} in file @file{.../info/dir}. You can put new entries +in that menu just like any other menu. The Info Directory is @emph{not} the +same as the file directory called @file{info}. It happens that many of +Info's files live on that file directory, but they do not have to; and +files on that directory are not automatically listed in the Info +Directory node. + + Also, although the Info node graph is claimed to be a ``hierarchy'', +in fact it can be @emph{any} directed graph. Shared structures and +pointer cycles are perfectly possible, and can be used if they are +appropriate to the meaning to be expressed. There is no need for all +the nodes in a file to form a connected structure. In fact, this file +has two connected components. You are in one of them, which is under +the node @samp{Top}; the other contains the node @samp{Help} which the +@kbd{h} command goes to. In fact, since there is no garbage +collector, nothing terrible happens if a substructure is not pointed +to, but such a substructure is rather useless since nobody can +ever find out that it exists. + +@node Cross-refs, Tags, Menus, Advanced Info +@comment node-name, next, previous, up +@section Creating Cross References + + A cross reference can be placed anywhere in the text, unlike a menu +item which must go at the front of a line. A cross reference looks +like a menu item except that it has @samp{*note} instead of @kbd{*}. +It @emph{cannot} be terminated by a @samp{)}, because @samp{)}'s are +so often part of node names.

After +that, the macro command is available as a normal @texinfo{} command. +Here is what a definition looks like: + +@example +@@macro @var{name}@{@var{arg1}, @var{@dots{}} @var{argn}@} +@var{@texinfo{} commands@dots{}} +@@end macro +@end example + +The arguments that you specify that the macro takes are expanded with +the actual parameters used when calling the macro if they are seen +surrounded by backslashes. For example, here is a definition of +@code{@@codeitem}, a macro which can be used wherever @code{@@item} can +be used, but which surrounds its argument with @code{@@code@{@dots{}@}}. + +@example +@@macro codeitem@{item@} +@@item @@code@{\item\@} +@@end macro +@end example + +When the macro is expanded, all of the text between the @code{@@macro} +and @code{@@end macro} is inserted into the document at the expansion +point, with the actual parameters substituted for the named parameters. +So, a call to the above macro might look like: + +@example +@@codeitem@{Foo@} +@end example + +and @makeinfo{} would execute the following code: + +@example +@@item @@code@{Foo@} +@end example + +A special case is made for macros which only take a single argument, and +which are invoked without any brace characters (i.e., +@samp{@{}@dots{}@samp{@}}) surrounding an argument; the rest of the line +is supplied as is as the sole argument to the macro. This special case +allows one to redefine some standard @texinfo{} commands without +modifying the input file. Along with the non-recursive action of macro +invocation, one can easily redefine the sectioning commands to also +provide index entries: + +@example +@@macro chapter@{name@} +@@chapter \name\ +@@findex \name\ +@@end macro +@end example + +Thus, the text: + +@example +@@chapter strlen +@end example + +will expand to: + +@example +@@chapter strlen +@@findex strlen +@end example + +@section Using Macros Recursively + +Normally, while a particular macro is executing, any call to that macro +will be seen as a call to a builtin @texinfo{} command. This allows one +to redefine a builtin @texinfo{} command as a macro, and then use that +command within the definition of the macro itself. For example, one +might wish to make sure that whereever a term was defined with +@code{@@dfn@{@dots{}@}}, the location of the definition would appear +in the concept index for the manual. Here is a macro which redefines +@code{@@dfn} to do just that: + +@example +@@macro dfn@{text@} +@@dfn@{\text\@} +@@cpindex \text\ +@@end macro +@end example + +Note that we used the builtin @texinfo{} command @code{@@dfn} within our +overriding macro definition. + +This behaviour itself can be overridden for macro execution by writing a +special @dfn{macro control command} in the definition of the macro. The +command is considered special because it doesn't affect the output text +directly, rather, it affects the way in which the macro is defined. One +such special command is @code{@@allow-recursion}. + +@example +@@macro silly@{arg@} +@@allow-recursion +\arg\ +@@end macro +@end example + +Now @code{@@silly} is a macro that can be used within a call to itself: + +@example +This text @@silly@{@@silly@{some text@}@} is ``some text''. +@end example + +@section Using @texinfo{} Macros As Arguments + +@printindex cp +How to use @texinfo{} macros as arguments to other @texinfo{} macros. + +@bye + + diff --git a/gnu/usr.bin/texinfo/doc/texinfo.tex b/gnu/usr.bin/texinfo/doc/texinfo.tex new file mode 100644 index 00000000000..ec9b7029432 --- /dev/null +++ b/gnu/usr.bin/texinfo/doc/texinfo.tex @@ -0,0 +1,4935 @@ +%% TeX macros to handle Texinfo files. +%% $Id: texinfo.tex,v 1.1 1997/08/01 22:01:12 kstailey Exp $ + +% Copyright (C) 1985, 86, 88, 90, 91, 92, 93, +% 94, 95, 96, 97 Free Software Foundation, Inc. + +%This texinfo.tex file is free software; you can redistribute it and/or +%modify it under the terms of the GNU General Public License as +%published by the Free Software Foundation; either version 2, or (at +%your option) any later version. + +%This texinfo.tex file is distributed in the hope that it will be +%useful, but WITHOUT ANY WARRANTY; without even the implied warranty +%of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Empty columns may be produced by supplying @tab's +% with nothing between them for as many times as empty columns are needed, +% ie, @tab@tab@tab will produce two empty columns. + +% @item, @tab, @multitable or @end multitable do not need to be on their +% own lines, but it will not hurt if they are. + +% Sample multitable: + +% @multitable {Column 1 template} {Column 2 template} {Column 3 template} +% @item first col stuff @tab second col stuff @tab third col +% @item +% first col stuff +% @tab +% second col stuff +% @tab +% third col +% @item first col stuff @tab second col stuff +% @tab Many paragraphs of text may be used in any column. +% +% They will wrap at the width determined by the template. +% @item@tab@tab This will be in third column. +% @end multitable + +% Default dimensions may be reset by user. +% @multitableparskip is vertical space between paragraphs in table. +% @multitableparindent is paragraph indent in table. +% @multitablecolmargin is horizontal space to be left between columns. +% @multitablelinespace is space to leave between table items, baseline +% to baseline. +% 0pt means it depends on current normal line spacing. + +%%%% +% Dimensions + +\newskip\multitableparskip +\newskip\multitableparindent +\newdimen\multitablecolspace +\newskip\multitablelinespace +\multitableparskip=0pt +\multitableparindent=6pt +\multitablecolspace=12pt +\multitablelinespace=0pt + +%%%% +% Macros used to set up halign preamble: +\let\endsetuptable\relax +\def\xendsetuptable{\endsetuptable} +\let\columnfractions\relax +\def\xcolumnfractions{\columnfractions} +\newif\ifsetpercent + +%% 2/1/96, to allow fractions to be given with more than one digit. +\def\pickupwholefraction#1 {\global\advance\colcount by1 % +\expandafter\xdef\csname col\the\colcount\endcsname{.#1\hsize}% +\setuptable} + +\newcount\colcount +\def\setuptable#1{\def\firstarg{#1}% +\ifx\firstarg\xendsetuptable\let\go\relax% +\else + \ifx\firstarg\xcolumnfractions\global\setpercenttrue% + \else + \ifsetpercent + \let\go\pickupwholefraction % In this case arg of setuptable + % is the decimal point before the + % number given in percent of hsize. + % We don't need this so we don't use it. + \else + \global\advance\colcount by1 + \setbox0=\hbox{#1 }% Add a normal word space as a separator; + % typically that is always in the input, anyway. + \expandafter\xdef\csname col\the\colcount\endcsname{\the\wd0}% + \fi% + \fi% +\ifx\go\pickupwholefraction\else\let\go\setuptable\fi% +\fi\go} + +%%%% +% multitable syntax +\def\tab{&\hskip1sp\relax} % 2/2/96 + % tiny skip here makes sure this column space is + % maintained, even if it is never used. + + +%%%% +% @multitable ... @end multitable definitions: + +\def\multitable{\parsearg\dotable} + +\def\dotable#1{\bgroup +\let\item\cr +\tolerance=9500 +\hbadness=9500 +\setmultitablespacing +\parskip=\multitableparskip +\parindent=\multitableparindent +\overfullrule=0pt +\global\colcount=0\relax% +\def\Emultitable{\global\setpercentfalse\global\everycr{}\cr\egroup\egroup}% + % To parse everything between @multitable and @item : +\setuptable#1 \endsetuptable + % Need to reset this to 0 after \setuptable. +\global\colcount=0\relax% + % + % This preamble sets up a generic column definition, which will + % be used as many times as user calls for columns. + % \vtop will set a single line and will also let text wrap and + % continue for many paragraphs if desired. +\halign\bgroup&\global\advance\colcount by 1\relax% +\multistrut\vtop{\hsize=\expandafter\csname col\the\colcount\endcsname + % In order to keep entries from bumping into each other + % we will add a \leftskip of \multitablecolspace to all columns after + % the first one. + % If a template has been used, we will add \multitablecolspace + % to the width of each template entry. + % If user has set preamble in terms of percent of \hsize + % we will use that dimension as the width of the column, and + % the \leftskip will keep entries from bumping into each other. + % Table will start at left margin and final column will justify at + % right margin. +\ifnum\colcount=1 +\else + \ifsetpercent + \else + % If user has <not> set preamble in terms of percent of \hsize + % we will advance \hsize by \multitablecolspace + \advance\hsize by \multitablecolspace + \fi + % In either case we will make \leftskip=\multitablecolspace: +\leftskip=\multitablecolspace +\fi + % Ignoring space at the beginning and end avoids an occasional spurious + % blank line, when TeX decides to break the line at the space before the + % box from the multistrut, so the strut ends up on a line by itself. + % For example: + % @multitable @columnfractions .11 .89 + % @item @code{#} + % @tab Legal holiday which is valid in major parts of the whole country. + % Is automatically provided with highlighting sequences respectively marking + % characters. + \noindent\ignorespaces##\unskip\multistrut}\cr + % \everycr will reset column counter, \colcount, at the end of + % each line.

From the same Texinfo source file, you can create a +menu-driven, on-line Info file with nodes, menus, cross references, +and indices. You can, if you wish, make the chapters and sections of +the printed document correspond to the nodes of the on-line +information; and you use the same cross references and indices for +both the Info file and the printed work. @cite{The GNU +Emacs Manual} is a good example of a Texinfo file, as is this manual.@refill + +To make a printed document, you process a Texinfo source file with the +@TeX{} typesetting program. This creates a DVI file that you can +typeset and print as a book or report. (Note that the Texinfo language +is completely different from @TeX{}'s usual language, plain @TeX{}.) If +you do not have @TeX{}, but do have @code{troff} or @code{nroff}, you +can use the @code{texi2roff} program instead.@refill + +To make an Info file, you process a Texinfo source file with the +@code{makeinfo} utility or Emacs's @code{texinfo-format-buffer} command; +this creates an Info file that you can install on-line.@refill + +@TeX{} and @code{texi2roff} work with many types of printers; similarly, +Info works with almost every type of computer terminal. This power +makes Texinfo a general purpose system, but brings with it a constraint, +which is that a Texinfo file may contain only the customary +``typewriter'' characters (letters, numbers, spaces, and punctuation +marks) but no special graphics.@refill + +A Texinfo file is a plain @sc{ascii} file containing text and +@dfn{@@-commands} (words preceded by an @samp{@@}) that tell the +typesetting and formatting programs what to do. You may edit a +Texinfo file with any text editor; but it is especially convenient to +use GNU Emacs since that editor has a special mode, called Texinfo +mode, that provides various Texinfo-related features. (@xref{Texinfo +Mode}.)@refill + +Before writing a Texinfo source file, you should become familiar with +the Info documentation reading program and learn about nodes, +menus, cross references, and the rest. (@inforef{Top, info, info}, +for more information.)@refill + +You can use Texinfo to create both on-line help and printed manuals; +moreover, Texinfo is freely redistributable. For these reasons, Texinfo +is the format in which documentation for GNU utilities and libraries is +written.@refill + +@node Info Files, Printed Books, Using Texinfo, Overview +@comment node-name, next, previous, up +@section Info files +@cindex Info files + +An Info file is a Texinfo file formatted so that the Info documentation +reading program can operate on it. (@code{makeinfo} +and @code{texinfo-format-buffer} are two commands that convert a Texinfo file +into an Info file.)@refill + +Info files are divided into pieces called @dfn{nodes}, each of which +contains the discussion of one topic. Each node has a name, and +contains both text for the user to read and pointers to other nodes, +which are identified by their names. The Info program displays one node +at a time, and provides commands with which the user can move to other +related nodes.@refill + +@ifinfo +@inforef{Top, info, info}, for more information about using Info.@refill +@end ifinfo + +Each node of an Info file may have any number of child nodes that +describe subtopics of the node's topic. The names of child +nodes are listed in a @dfn{menu} within the parent node; this +allows you to use certain Info commands to move to one of the child +nodes. Generally, an Info file is organized like a book. If a node +is at the logical level of a chapter, its child nodes are at the level +of sections; likewise, the child nodes of sections are at the level +of subsections.@refill + +All the children of any one parent are linked together in a +bidirectional chain of `Next' and `Previous' pointers. The `Next' +pointer provides a link to the next section, and the `Previous' pointer +provides a link to the previous section. This means that all the nodes +that are at the level of sections within a chapter are linked together. +Normally the order in this chain is the same as the order of the +children in the parent's menu. Each child node records the parent node +name as its `Up' pointer. The last child has no `Next' pointer, and the +first child has the parent both as its `Previous' and as its `Up' +pointer.@footnote{In some documents, the first child has no `Previous' +pointer. Occasionally, the last child has the node name of the next +following higher level node as its `Next' pointer.}@refill + +The book-like structuring of an Info file into nodes that correspond +to chapters, sections, and the like is a matter of convention, not a +requirement. The `Up', `Previous', and `Next' pointers of a node can +point to any other nodes, and a menu can contain any other nodes. +Thus, the node structure can be any directed graph. But it is usually +more comprehensible to follow a structure that corresponds to the +structure of chapters and sections in a printed book or report.@refill + +In addition to menus and to `Next', `Previous', and `Up' pointers, Info +provides pointers of another kind, called references, that can be +sprinkled throughout the text. This is usually the best way to +represent links that do not fit a hierarchical structure.@refill + +Usually, you will design a document so that its nodes match the +structure of chapters and sections in the printed output. But +occasionally there are times when this is not right for the material +being discussed. Therefore, Texinfo uses separate commands to specify +the node structure for the Info file and the section structure for the +printed output.@refill + +Generally, you enter an Info file through a node that by convention is +named `Top'. This node normally contains just a brief summary of the +file's purpose, and a large menu through which the rest of the file is +reached. From this node, you can either traverse the file +systematically by going from node to node, or you can go to a specific +node listed in the main menu, or you can search the index menus and then +go directly to the node that has the information you want. Alternatively, +with the standalone Info program, you can specify specific menu items on +the command line (@pxref{Top,,, info, Info}). + +If you want to read through an Info file in sequence, as if it were a +printed manual, you can hit @key{SPC} repeatedly, or you get the whole +file with the advanced Info command @kbd{g *}.

If you are reading this +manual straight through from the beginning, you may want to skim through +this chapter briefly and come back to it after reading succeeding +chapters which describe the Texinfo formatting language in +detail.@refill + +@menu +* Texinfo Mode Overview:: How Texinfo mode can help you. +* Emacs Editing:: Texinfo mode adds to GNU Emacs' general + purpose editing features. +* Inserting:: How to insert frequently used @@-commands. +* Showing the Structure:: How to show the structure of a file. +* Updating Nodes and Menus:: How to update or create new nodes and menus. +* Info Formatting:: How to format for Info. +* Printing:: How to format and print part or all of a file. +* Texinfo Mode Summary:: Summary of all the Texinfo mode commands. +@end menu + +@node Texinfo Mode Overview, Emacs Editing, Texinfo Mode, Texinfo Mode +@ifinfo +@heading Texinfo Mode Overview +@end ifinfo + +Texinfo mode provides special features for working with Texinfo +files:@refill + +@itemize @bullet +@item +Insert frequently used @@-commands. @refill + +@item +Automatically create @code{@@node} lines. + +@item +Show the structure of a Texinfo source file.@refill + +@item +Automatically create or update the `Next', +`Previous', and `Up' pointers of a node. + +@item +Automatically create or update menus.@refill + +@item +Automatically create a master menu.@refill + +@item +Format a part or all of a file for Info.@refill + +@item +Typeset and print part or all of a file.@refill +@end itemize + +Perhaps the two most helpful features are those for inserting frequently +used @@-commands and for creating node pointers and menus.@refill + +@node Emacs Editing, Inserting, Texinfo Mode Overview, Texinfo Mode +@section The Usual GNU Emacs Editing Commands + +In most cases, the usual Text mode commands work the same in Texinfo +mode as they do in Text mode. Texinfo mode adds new editing commands +and tools to GNU Emacs' general purpose editing features. The major +difference concerns filling. In Texinfo mode, the paragraph +separation variable and syntax table are redefined so that Texinfo +commands that should be on lines of their own are not inadvertently +included in paragraphs. Thus, the @kbd{M-q} (@code{fill-paragraph}) +command will refill a paragraph but not mix an indexing command on a +line adjacent to it into the paragraph.@refill + +In addition, Texinfo mode sets the @code{page-delimiter} variable to +the value of @code{texinfo-chapter-level-regexp}; by default, this is +a regular expression matching the commands for chapters and their +equivalents, such as appendices. With this value for the page +delimiter, you can jump from chapter title to chapter title with the +@kbd{C-x ]} (@code{forward-page}) and @kbd{C-x [} +(@code{backward-page}) commands and narrow to a chapter with the +@kbd{C-x p} (@code{narrow-to-page}) command. (@xref{Pages, , ,emacs, +The GNU Emacs Manual}, for details about the page commands.)@refill + +You may name a Texinfo file however you wish, but the convention is to +end a Texinfo file name with one of the three extensions +@file{.texinfo}, @file{.texi}, or @file{.tex}. A longer extension is +preferred, since it is explicit, but a shorter extension may be +necessary for operating systems that limit the length of file names. +GNU Emacs automatically enters Texinfo mode when you visit a file with +a @file{.texinfo} or @file{.texi} +extension. Also, Emacs switches to Texinfo mode +when you visit a +file that has @samp{-*-texinfo-*-} in its first line. If ever you are +in another mode and wish to switch to Texinfo mode, type @code{M-x +texinfo-mode}.@refill + +Like all other Emacs features, you can customize or enhance Texinfo +mode as you wish. In particular, the keybindings are very easy to +change.

Use a negative argument to enclose the previous +word or words. If you do not specify a prefix argument, Emacs inserts +the @@-command string and positions the cursor between the braces. This +feature works only for those @@-commands that operate on a word or words +within one line, such as @code{@@kbd} and @code{@@var}.@refill + +This set of insert commands was created after analyzing the frequency +with which different @@-commands are used in the @cite{GNU Emacs +Manual} and the @cite{GDB Manual}.

Only the node name is +required, but a description helps explain what the node is about. +@xref{Menu Parts, , The Parts of a Menu}.)@refill + +To use @code{texinfo-start-menu-description}, position point in a menu +entry line and type @kbd{C-c C-c C-d}.

The function does not insert the title if the menu entry +line already contains a description.@refill + +This command is only an aid to writing descriptions; it does not do the +whole job.

(This is how the +@code{texinfo-show-structure} command worked without an argument in +the first version of Texinfo.

You can use @code{texinfo-show-structure} with a prefix +argument to check whether the `Next', `Previous', and `Up' pointers of +an @code{@@node} line are correct.@refill + +Often, when you are working on a manual, you will be interested only +in the structure of the current chapter.

You cannot interpose more than one line between +the @code{@@node} line and the structuring command line; and you may +interpose only an @code{@@comment} line or an @code{@@ifinfo} line. + +Commands which work on a whole buffer require that the `Top' node be +followed by a node with an @code{@@chapter} or equivalent-level command. +Note that the menu updating commands will not create a main or master +menu for a Texinfo file that has only @code{@@chapter}-level nodes! The +menu updating commands only create menus @emph{within} nodes for lower level +nodes. To create a menu of chapters, you must provide a `Top' +node.@refill + +The menu updating commands remove menu entries that refer to other Info +files since they do not refer to nodes within the current buffer. This +is a deficiency. Rather than use menu entries, you can use cross +references to refer to other Info files. None of the updating commands +affect cross references.@refill + +Texinfo mode has five updating commands that are used most often: two +are for updating the node pointers or menu of a single node (or a +region); two are for updating every node pointer and menu in a file; +and one, the @code{texinfo-master-menu} command, is for creating a +master menu for a complete file, and optionally, for updating every +node and menu in the whole Texinfo file.@refill + +The @code{texinfo-master-menu} command is the primary command:@refill + +@table @kbd +@item C-c C-u m +@itemx M-x texinfo-master-menu +@findex texinfo-master-menu +Create or update a master menu that includes all the other menus +(incorporating the descriptions from pre-existing menus, if +any).@refill + +With an argument (prefix argument, @kbd{C-u,} if interactive), first create or +update all the nodes and all the regular menus in the buffer before +constructing the master menu.

This +way, an index entry points to the first page of a paragraph that is +split across pages. + +Here are more hints we have found valuable: + +@itemize @bullet +@item +Write each index entry differently, so each entry refers to a different +place in the document. + +@item +Write index entries only where a topic is discussed significantly. For +example, it is not useful to index ``debugging information'' in a +chapter on reporting bugs. Someone who wants to know about debugging +information will certainly not find it in that chapter. + +@item +Consistently capitalize the first word of every concept index entry, +or else consistently use lower case. Terse entries often call for +lower case; longer entries for capitalization. Whichever case +convention you use, please use one or the other consistently! Mixing +the two styles looks bad. + +@item +Always capitalize or use upper case for those words in an index for +which this is proper, such as names of countries or acronyms. Always +use the appropriate case for case-sensitive names, such as those in C or +Lisp. + +@item +Write the indexing commands that refer to a whole section immediately +after the section command, and write the indexing commands that refer to +the paragraph before the paragraph. + +@need 1000 +In the example that follows, a blank line comes after the index +entry for ``Leaping'': + +@example +@group +@@section The Dog and the Fox +@@cindex Jumping, in general +@@cindex Leaping + +@@cindex Dog, lazy, jumped over +@@cindex Lazy dog jumped over +@@cindex Fox, jumps over dog +@@cindex Quick fox jumps over dog +The quick brown fox jumps over the lazy dog. +@end group +@end example + +@noindent +(Note that the example shows entries for the same concept that are +written in different ways---@samp{Lazy dog}, and @samp{Dog, lazy}---so +readers can look up the concept in different ways.) +@end itemize + +@subsubheading Blank Lines + +@itemize @bullet +@item +Insert a blank line between a sectioning command and the first following +sentence or paragraph, or between the indexing commands associated with +the sectioning command and the first following sentence or paragraph, as +shown in the tip on indexing.

This practice goes +against publishing conventions in the United States, but enables the +reader to distinguish between the contents of the quotation and the +whole passage. + +For example, you should write the following sentence with the period +outside the end quotation marks: + +@example +Evidently, @samp{au} is an abbreviation for ``author''. +@end example + +@noindent +since @samp{au} does @emph{not} serve as an abbreviation for +@samp{author.} (with a period following the word). + +@subsubheading Introducing New Terms + +@itemize @bullet +@item +Introduce new terms so that a reader who does not know them can +understand them from context; or write a definition for the term. + +For example, in the following, the terms ``check in'', ``register'' and +``delta'' are all appearing for the first time; the example sentence should be +rewritten so they are understandable. + +@quotation +The major function assists you in checking in a file to your +version control system and registering successive sets of changes to +it as deltas. +@end quotation + +@item +Use the @code{@@dfn} command around a word being introduced, to indicate +that the reader should not expect to know the meaning already, and +should expect to learn the meaning from this passage. +@end itemize + +@subsubheading @@pxref + +@c !!! maybe include this in the tips on pxref +@ignore +By the way, it is okay to use pxref with something else in front of +it within the parens, as long as the pxref is followed by the close +paren, and the material inside the parens is not part of a larger +sentence. Also, you can use xref inside parens as part of a complete +sentence so long as you terminate the cross reference with punctuation. +@end ignore +Absolutely never use @code{@@pxref} except in the special context for +which it is designed: inside parentheses, with the closing parenthesis +following immediately after the closing brace. One formatter +automatically inserts closing punctuation and the other does not. This +means that the output looks right both in printed output and in an Info +file, but only when the command is used inside parentheses. + +@subsubheading Invoking from a Shell + +You can invoke programs such as Emacs, GCC, and @code{gawk} from a +shell. The documentation for each program should contain a section that +describes this. Unfortunately, if the node names and titles for these +sections are all different, readers find it hard to search for the +section.@refill + +Name such sections with a phrase beginning with the word +@w{`Invoking @dots{}'}, as in `Invoking Emacs'; this way +users can find the section easily. + +@subsubheading ANSI C Syntax + +When you use @code{@@example} to describe a C function's calling +conventions, use the ANSI C syntax, like this:@refill + +@example +void dld_init (char *@@var@{path@}); +@end example + +@noindent +And in the subsequent discussion, refer to the argument values by +writing the same argument names, again highlighted with +@code{@@var}.@refill + +@need 800 +Avoid the obsolete style that looks like this:@refill + +@example +#include <dld.h> + +dld_init (path) +char *path; +@end example + +Also, it is best to avoid writing @code{#include} above the +declaration just to indicate that the function is declared in a +header file. The practice may give the misimpression that the +@code{#include} belongs near the declaration of the function. Either +state explicitly which header file holds the declaration or, better +yet, name the header file used for a group of functions at the +beginning of the section that describes the functions.@refill + +@subsubheading Bad Examples + +Here are several examples of bad writing to avoid: + +In this example, say, `` @dots{} you must @code{@@dfn}@{check +in@} the new version.'' That flows better. + +@quotation +When you are done editing the file, you must perform a +@code{@@dfn}@{check in@}. +@end quotation + +In the following example, say, ``@dots{} makes a unified interface such as VC +mode possible.'' + +@quotation +SCCS, RCS and other version-control systems all perform similar +functions in broadly similar ways (it is this resemblance which makes +a unified control mode like this possible). +@end quotation + +And in this example, you should specify what `it' refers to: + +@quotation +If you are working with other people, it assists in coordinating +everyone's changes so they do not step on each other. +@end quotation + +@subsubheading And Finally @dots{} + +@itemize @bullet +@item +Pronounce @TeX{} as if the @samp{X} were a Greek `chi', as the last +sound in the name `Bach'.

Likewise, you should not end an included +file with an @code{@@bye} command; nothing after @code{@@bye} is +formatted.@refill + +In the past, you were required to write an @code{@@setfilename} line at the +beginning of an included file, but no longer. Now, it does not matter +whether you write such a line. If an @code{@@setfilename} line exists +in an included file, it is ignored.@refill + +Conventionally, an included file begins with an @code{@@node} line that +is followed by an @code{@@chapter} line.

However, the simple Emacs node and menu creating and +updating commands do not work with multiple Texinfo files. Thus you +cannot use these commands to fill in the `Next', `Previous', and `Up' +pointers of the @code{@@node} line that begins the included file. Also, +you cannot use the regular commands to create a master menu for the +whole file.

In a printed +manual, all the references were within the same document, so @TeX{} +could automatically determine the references' page numbers. The Info +formatting commands used include files only for creating joint +indices; each of the individual Texinfo files had to be formatted for +Info individually. (Each, therefore, required its own +@code{@@setfilename} line.)@refill + +However, because large Info files are now split automatically, it is +no longer necessary to keep them small.@refill + +Nowadays, multiple Texinfo files are used mostly for large documents, +such as @cite{The GNU Emacs Lisp Reference Manual}, and for projects +in which several different people write different sections of a +document simultaneously.@refill + +In addition, the Info formatting commands have been extended to work +with the @code{@@include} command so as to create a single large Info +file that is split into smaller files if necessary.

Non-alphabetic commands are +almost always part of the text within a paragraph, and never take any +argument.

Since this is the case, GNU Info (both the +Emacs and standalone versions) have several commands which allow you to +move the cursor about the screen. The notation used in this manual to +describe keystrokes is identical to the notation used within the Emacs +manual, and the GNU Readline manual. @xref{Characters, , Character +Conventions, emacs, the GNU Emacs Manual}, if you are unfamilar with the +notation. + +The following table lists the basic cursor movement commands in Info. +Each entry consists of the key sequence you should type to execute the +cursor movement, the @code{M-x}@footnote{@code{M-x} is also a command; it +invokes @code{execute-extended-command}. @xref{M-x, , Executing an +extended command, emacs, the GNU Emacs Manual}, for more detailed +information.} command name (displayed in parentheses), and a short +description of what the command does. All of the cursor motion commands +can take an @dfn{numeric} argument (@pxref{Miscellaneous Commands, +@code{universal-argument}}), to find out how to supply them. With a +numeric argument, the motion commands are simply executed that +many times; for example, a numeric argument of 4 given to +@code{next-line} causes the cursor to move down 4 lines. With a +negative numeric argument, the motion is reversed; an argument of -4 +given to the @code{next-line} command would cause the cursor to move +@emph{up} 4 lines. + +@table @asis +@item @code{C-n} (@code{next-line}) +@kindex C-n +@findex next-line +Moves the cursor down to the next line. + +@item @code{C-p} (@code{prev-line}) +@kindex C-p +@findex prev-line +Move the cursor up to the previous line. + +@item @code{C-a} (@code{beginning-of-line}) +@kindex C-a, in Info windows +@findex beginning-of-line +Move the cursor to the start of the current line. + +@item @code{C-e} (@code{end-of-line}) +@kindex C-e, in Info windows +@findex end-of-line +Moves the cursor to the end of the current line. + +@item @code{C-f} (@code{forward-char}) +@kindex C-f, in Info windows +@findex forward-char +Move the cursor forward a character. + +@item @code{C-b} (@code{backward-char}) +@kindex C-b, in Info windows +@findex backward-char +Move the cursor backward a character. + +@item @code{M-f} (@code{forward-word}) +@kindex M-f, in Info windows +@findex forward-word +Moves the cursor forward a word. + +@item @code{M-b} (@code{backward-word}) +@kindex M-b, in Info winows +@findex backward-word +Moves the cursor backward a word. + +@item @code{M-<} (@code{beginning-of-node}) +@itemx @code{b} +@kindex b, in Info winows +@kindex M-< +@findex beginning-of-node +Moves the cursor to the start of the current node. + +@item @code{M->} (@code{end-of-node}) +@kindex M-> +@findex end-of-node +Moves the cursor to the end of the current node. + +@item @code{M-r} (@code{move-to-window-line}) +@kindex M-r +@findex move-to-window-line +Moves the cursor to a specific line of the window.

The +@samp{s} command prompts you for a string in the echo area, and then +searches the remainder of the info file for an ocurrence of that string. +If the string is found, the node containing it is selected, and the +cursor is left positioned at the start of the found string. Subsequent +@samp{s} commands show you the default search string within @samp{[} and +@samp{]}; pressing @key{RET} instead of typing a new string will use the +default search string. + +@dfn{Incremental searching} is similar to basic searching, but the +string is looked up while you are typing it, instead of waiting until +the entire search string has been specified. + +@node Xref Commands +@chapter Selecting Cross References + +We have already discussed the @samp{Next}, @samp{Prev}, and @samp{Up} +pointers which appear at the top of a node. In addition to these +pointers, a node may contain other pointers which refer you to a +different node, perhaps in another info file. Such pointers are called +@dfn{cross references}, or @dfn{xrefs} for short. + +@menu +* Parts of an Xref:: What a cross reference is made of. +* Selecting Xrefs:: Commands for selecting menu or note items. +@end menu + +@node Parts of an Xref +@section Parts of an Xref + +Cross references have two major parts: the first part is called the +@dfn{label}; it is the name that you can use to refer to the cross +reference, and the second is the @dfn{target}; it is the full name of +the node that the cross reference points to. + +The target is separated from the label by a colon @samp{:}; first the +label appears, and then the target. For example, in the sample menu +cross reference below, the single colon separates the label from the +target. + +@example +* Foo Label: Foo Target. More information about Foo. +@end example + +Note the @samp{.} which ends the name of the target. The @samp{.} is +not part of the target; it serves only to let Info know where the target +name ends. + +A shorthand way of specifying references allows two adjacent colons to +stand for a target name which is the same as the label name: + +@example +* Foo Commands:: Commands pertaining to Foo. +@end example + +In the above example, the name of the target is the same as the name of +the label, in this case @code{Foo Commands}. + +You will normally see two types of cross references while viewing nodes: +@dfn{menu} references, and @dfn{note} references. Menu references +appear within a node's menu; they begin with a @samp{*} at the beginning +of a line, and continue with a label, a target, and a comment which +describes what the contents of the node pointed to contains. + +Note references appear within the body of the node text; they begin with +@code{*Note}, and continue with a label and a target. + +Like @samp{Next}, @samp{Prev} and @samp{Up} pointers, cross references +can point to any valid node. They are used to refer you to a place +where more detailed information can be found on a particular subject. +Here is a cross reference which points to a node within the Texinfo +documentation: @xref{xref, , Writing an Xref, texinfo, the Texinfo +Manual}, for more information on creating your own texinfo cross +references. + +@node Selecting Xrefs +@section Selecting Xrefs + +The following table lists the Info commands which operate on menu items. + +@table @asis +@item @code{1} (@code{menu-digit}) +@itemx @code{2} @dots{} @code{9} +@cindex 1 @dots{} 9, in Info windows +@kindex 1 @dots{} 9, in Info windows +@findex menu-digit +Within an Info window, pressing a single digit, (such as @samp{1}), +selects that menu item, and places its node in the current window. +For convenience, there is one exception; pressing @samp{0} selects the +@emph{last} item in the node's menu. + +@item @code{0} (@code{last-menu-item}) +@kindex 0, in Info windows +@findex last-menu-item +Select the last item in the current node's menu. + +@item @code{m} (@code{menu-item}) +@kindex m +@findex menu-item +Reads the name of a menu item in the echo area and selects its node. +Completion is available while reading the menu label. + +@item @code{M-x find-menu} +@findex find-menu +Moves the cursor to the start of this node's menu. +@end table + +This table lists the Info commands which operate on note cross references. + +@table @asis +@item @code{f} (@code{xref-item}) +@itemx @code{r} +@kindex f +@kindex r +@findex xref-item +Reads the name of a note cross reference in the echo area and selects +its node.

When a node is selected, a +window containing the footnotes which appear in that node is created, +and the footnotes are displayed within the new window. The window that +Info creates to contain the footnotes is called @samp{*Footnotes*}. If +a node is selected which contains no footnotes, and a @samp{*Footnotes*} +window is on the screen, the @samp{*Footnotes*} window is deleted. +Footnote windows created in this fashion are not automatically tiled so +that they can use as little of the display as is possible. + +@item automatic-tiling +@vindex automatic-tiling +When set to @code{On}, creating or deleting a window resizes other +windows. This variable is @code{Off} by default. Normally, typing +@samp{C-x 2} divides the current window into two equal parts. When +@code{automatic-tiling} is set to @code{On}, all of the windows are +resized automatically, keeping an equal number of lines visible in each +window. There are exceptions to the automatic tiling; specifically, the +windows @samp{*Completions*} and @samp{*Footnotes*} are @emph{not} +resized through automatic tiling; they remain their original size. + +@item visible-bell +@vindex visible-bell +When set to @code{On}, GNU Info attempts to flash the screen instead of +ringing the bell. This variable is @code{Off} by default. Of course, +Info can only flash the screen if the terminal allows it; in the case +that the terminal does not allow it, the setting of this variable has no +effect. However, you can make Info perform quietly by setting the +@code{errors-ring-bell} variable to @code{Off}. + +@item errors-ring-bell +@vindex errors-ring-bell +When set to @code{On}, errors cause the bell to ring. The default +setting of this variable is @code{On}. + +@item gc-compressed-files +@vindex gc-compressed-files +When set to @code{On}, Info garbage collects files which had to be +uncompressed. The default value of this variable is @code{Off}. +Whenever a node is visited in Info, the info file containing that node +is read into core, and Info reads information about the tags and nodes +contained in that file. Once the tags information is read by Info, it +is never forgotten. However, the actual text of the nodes does not need +to remain in core unless a particular info window needs it. For +non-compressed files, the text of the nodes does not remain in core when +it is no longer in use. But de-compressing a file can be a time +consuming operation, and so Info tries hard not to do it twice. +@code{gc-compressed-files} tells Info it is okay to garbage collect the +text of the nodes of a file which was compressed on disk. + +@item show-index-match +@vindex show-index-match +When set to @code{On}, the portion of the matched search string is +highlighted in the message which explains where the matched search +string was found. The default value of this variable is @code{On}. +When Info displays the location where an index match was found, +(@pxref{Searching Commands, , @code{next-index-match}}), the portion of the +string that you had typed is highlighted by displaying it in the inverse +case from its surrounding characters. + +@item scroll-behaviour +@vindex scroll-behaviour +Controls what happens when forward scrolling is requested at the end of +a node, or when backward scrolling is requested at the beginning of a +node. The default value for this variable is @code{Continuous}. There +are three possible values for this variable: + +@table @code +@item Continuous +Tries to get the first item in this node's menu, or failing that, the +@samp{Next} node, or failing that, the @samp{Next} of the @samp{Up}. +This behaviour is identical to using the @samp{]} +(@code{global-next-node}) and @samp{[} (@code{global-prev-node}) +commands. + +@item Next Only +Only tries to get the @samp{Next} node. + +@item Page Only +Simply gives up, changing nothing. If @code{scroll-behaviour} is +@code{Page Only}, no scrolling command can change the node that is being +viewed. +@end table + +@item scroll-step +@vindex scroll-step +The number of lines to scroll when the cursor moves out of the window. +Scrolling happens automatically if the cursor has moved out of the +visible portion of the node text when it is time to display. Usually +the scrolling is done so as to put the cursor on the center line of the +current window. However, if the variable @code{scroll-step} has a +nonzero value, Info attempts to scroll the node text by that many lines; +if that is enough to bring the cursor back into the window, that is what +is done. The default value of this variable is 0, thus placing the +cursor (and the text it is attached to) in the center of the window. +Setting this variable to 1 causes a kind of "smooth scrolling" which +some people prefer. + +@item ISO-Latin +@cindex ISO Latin characters +@vindex ISO-Latin +When set to @code{On}, Info accepts and displays ISO Latin characters. +By default, Info assumes an ASCII character set. @code{ISO-Latin} tells +Info that it is running in an environment where the European standard +character set is in use, and allows you to input such characters to +Info, as well as display them. +@end table + +@c The following node and its children are currently unfinished.
