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. -; -; If you do a @definfoenclose{} on the name of a pre-defined macro (such -; as @emph{}, @strong{}, @tt{}, or @i{}) the enclosure definition will -; override the built-in definition. -; -; 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'. - -(put 'definfoenclose 'texinfo-format 'texinfo-define-info-enclosure) -(defun texinfo-define-info-enclosure () - (let* ((args (texinfo-format-parse-line-args)) - (command-name (nth 0 args)) - (beginning-delimiter (or (nth 1 args) "")) - (end-delimiter (or (nth 2 args) ""))) - (texinfo-discard-command) - (setq texinfo-enclosure-list - (cons - (list command-name - (list - beginning-delimiter - end-delimiter)) - texinfo-enclosure-list)))) - - -;;; @var, @code and the like - -(put 'var 'texinfo-format 'texinfo-format-var) -; @sc a small caps font for TeX; formatted as `var' in Info -(put 'sc 'texinfo-format 'texinfo-format-var) -(defun texinfo-format-var () - (insert (upcase (texinfo-parse-arg-discard))) - (goto-char texinfo-command-start)) - -; various noops - -(put 'b 'texinfo-format 'texinfo-format-noop) -(put 'i 'texinfo-format 'texinfo-format-noop) -(put 'r 'texinfo-format 'texinfo-format-noop) -(put 't 'texinfo-format 'texinfo-format-noop) -(put 'w 'texinfo-format 'texinfo-format-noop) -(put 'asis 'texinfo-format 'texinfo-format-noop) -(put 'dmn 'texinfo-format 'texinfo-format-noop) -(put 'key 'texinfo-format 'texinfo-format-noop) -(put 'math 'texinfo-format 'texinfo-format-noop) -(put 'titlefont 'texinfo-format 'texinfo-format-noop) -(defun texinfo-format-noop () - (insert (texinfo-parse-arg-discard)) - (goto-char texinfo-command-start)) - -(put 'cite 'texinfo-format 'texinfo-format-code) -(put 'code 'texinfo-format 'texinfo-format-code) -(put 'file 'texinfo-format 'texinfo-format-code) -(put 'kbd 'texinfo-format 'texinfo-format-code) -(put 'samp 'texinfo-format 'texinfo-format-code) -(defun texinfo-format-code () - (insert "`" (texinfo-parse-arg-discard) "'") - (goto-char texinfo-command-start)) - -(put 'emph 'texinfo-format 'texinfo-format-emph) -(put 'strong 'texinfo-format 'texinfo-format-emph) -(defun texinfo-format-emph () - (insert "*" (texinfo-parse-arg-discard) "*") - (goto-char texinfo-command-start)) - -(put 'dfn 'texinfo-format 'texinfo-format-defn) -(put 'defn 'texinfo-format 'texinfo-format-defn) -(defun texinfo-format-defn () - (insert "\"" (texinfo-parse-arg-discard) "\"") - (goto-char texinfo-command-start)) - -(put 'bullet 'texinfo-format 'texinfo-format-bullet) -(defun texinfo-format-bullet () - "Insert an asterisk. -If used within a line, follow `@bullet' with braces." - (texinfo-optional-braces-discard) - (insert "*")) - - -;;; @example, @lisp, @quotation, @display, @smalllisp, @smallexample - -(put 'display 'texinfo-format 'texinfo-format-example) -(put 'example 'texinfo-format 'texinfo-format-example) -(put 'lisp 'texinfo-format 'texinfo-format-example) -(put 'quotation 'texinfo-format 'texinfo-format-example) -(put 'smallexample 'texinfo-format 'texinfo-format-example) -(put 'smalllisp 'texinfo-format 'texinfo-format-example) -(defun texinfo-format-example () - (texinfo-push-stack 'example nil) - (setq fill-column (- fill-column 5)) - (texinfo-discard-line)) - -(put 'example 'texinfo-end 'texinfo-end-example) -(put 'display 'texinfo-end 'texinfo-end-example) -(put 'lisp 'texinfo-end 'texinfo-end-example) -(put 'quotation 'texinfo-end 'texinfo-end-example) -(put 'smallexample 'texinfo-end 'texinfo-end-example) -(put 'smalllisp 'texinfo-end 'texinfo-end-example) -(defun texinfo-end-example () - (setq fill-column (+ fill-column 5)) - (texinfo-discard-command) - (let ((stacktop - (texinfo-pop-stack 'example))) - (texinfo-do-itemize (nth 1 stacktop)))) - -(put 'exdent 'texinfo-format 'texinfo-format-exdent) -(defun texinfo-format-exdent () - (texinfo-discard-command) - (delete-region (point) - (progn - (skip-chars-forward " ") - (point))) - (insert ?\b) - ;; Cancel out the deletion that texinfo-do-itemize - ;; is going to do at the end of this line. - (save-excursion - (end-of-line) - (insert "\n "))) - - -;;; @cartouche - -; The @cartouche command is a noop in Info; in a printed manual, -; it makes a box with rounded corners. - -(put 'cartouche 'texinfo-format 'texinfo-discard-line) -(put 'cartouche 'texinfo-end 'texinfo-discard-command) - - -;;; @flushleft and @format - -; The @flushleft command left justifies every line but leaves the -; right end ragged.
