- ;;; Define the Info enclosure command: @definfoenclose
-
- ; A `@definfoenclose' command may be used to define a highlighting
- ; command for Info, but not for TeX. A command defined using
- ; `@definfoenclose' marks text by enclosing it in strings that precede
- ; and follow the text.
- ;
- ; Presumably, if you define a command with `@definfoenclose` for Info,
- ; you will also define the same command in the TeX definitions file,
- ; `texinfo.tex' in a manner appropriate for typesetting.
- ;
- ; Write a `@definfoenclose' command on a line and follow it with three
- ; arguments separated by commas (commas are used as separators in an
- ; `@node' line in the same way). The first argument to
- ; `@definfoenclose' is the @-command name \(without the `@'\); the
- ; second argument is the Info start delimiter string; and the third
- ; argument is the Info end delimiter string. The latter two arguments
- ; enclose the highlighted text in the Info file. A delimiter string
- ; may contain spaces. Neither the start nor end delimiter is
- ; required. However, if you do not provide a start delimiter, you
- ; must follow the command name with two commas in a row; otherwise,
- ; the Info formatting commands will misinterpret the end delimiter
- ; string as a start delimiter string.
- ;
- ; An enclosure command defined this way takes one argument in braces.
- ;
- ; For example, you can write:
- ;
- ; @ifinfo
- ; @definfoenclose phoo, //, \\
- ; @end ifinfo
- ;
- ; near the beginning of a Texinfo file at the beginning of the lines
- ; to define `@phoo' as an Info formatting command that inserts `//'
- ; before and `\\' after the argument to `@phoo'. You can then write
- ; `@phoo{bar}' wherever you want `//bar\\' highlighted in Info.
- ;
- ; Also, for TeX formatting, you could write
- ;
- ; @iftex
- ; @global@let@phoo=@i
- ; @end iftex
- ;
- ; to define `@phoo' as a command that causes TeX to typeset
- ; the argument to `@phoo' in italics.
- ;
- ; Note that each definition applies to its own formatter: one for TeX,
- ; the other for texinfo-format-buffer or texinfo-format-region.
- ;
- ; Here is another example: write
- ;
- ; @definfoenclose headword, , :
- ;
- ; near the beginning of the file, to define `@headword' as an Info
- ; formatting command that inserts nothing before and a colon after the
- ; argument to `@headword'.

- ;;; Process included files: `@include' command
-
- ;; Updated 19 October 1990
- ;; In the original version, include files were ignored by Info but
- ;; incorporated in to the printed manual. To make references to the
- ;; included file, the Texinfo source file has to refer to the included
- ;; files using the `(filename)nodename' format for refering to other
- ;; Info files. Also, the included files had to be formatted on their
- ;; own. It was just like they were another file.
-
- ;; Currently, include files are inserted into the buffer that is
- ;; formatted for Info. If large, the resulting info file is split and
- ;; tagified. For current include files to work, the master menu must
- ;; refer to all the nodes, and the highest level nodes in the include
- ;; files must have the correct next, prev, and up pointers.
-
- ;; The included file may have an @setfilename and even an @settitle,
- ;; but not an `\input texinfo' line.
-
- ;; Updated 24 March 1993
- ;; In order for @raisesections and @lowersections to work, included
- ;; files must be inserted into the buffer holding the outer file
- ;; before other Info formatting takes place. So @include is no longer
- ;; is treated like other @-commands.
