199 | specific information. | |

514 | |
515 | It has these extra commands: | |
516 | \\{texinfo-mode-map} | |
517 | ||
d5aa8b02 | 518 | These are files that are used as input for TeX to make printed manuals |
c6cc04e9 RS |
519 | and also to be turned into Info files with \\[makeinfo-buffer] or |
520 | the `makeinfo' program. These files must be written in a very restricted and | |
d5aa8b02 | 521 | modified version of TeX input format. |
952d72ff RC |
522 | |
523 | Editing commands are like text-mode except that the syntax table is | |
d5aa8b02 RC |
524 | set up so expression commands skip Texinfo bracket groups. To see |
525 | what the Info version of a region of the Texinfo file will look like, | |
c6cc04e9 | 526 | use \\[makeinfo-region], which runs `makeinfo' on the current region. |
952d72ff | 527 | |
d5aa8b02 RC |
528 | You can show the structure of a Texinfo file with \\[texinfo-show-structure]. |
529 | This command shows the structure of a Texinfo file by listing the | |
530 | lines with the @-sign commands for @chapter, @section, and the like. | |
531 | These lines are displayed in another window called the *Occur* window. | |
532 | In that window, you can position the cursor over one of the lines and | |
533 | use \\[occur-mode-goto-occurrence], to jump to the corresponding spot | |
534 | in the Texinfo file. | |
952d72ff | 535 | |
d5aa8b02 | 536 | In addition, Texinfo mode provides commands that insert various |
952d72ff RC |
537 | frequently used @-sign commands into the buffer. You can use these |
538 | commands to save keystrokes. And you can insert balanced braces with | |
539 | \\[texinfo-insert-braces] and later use the command \\[up-list] to | |
540 | move forward past the closing brace. | |
541 | ||
d5aa8b02 | 542 | Also, Texinfo mode provides functions for automatically creating or |
952d72ff RC |
543 | updating menus and node pointers. These functions |
544 | ||
545 | * insert the `Next', `Previous' and `Up' pointers of a node, | |
546 | * insert or update the menu for a section, and | |
d5aa8b02 | 547 | * create a master menu for a Texinfo source file. |
952d72ff RC |
548 | |
549 | Here are the functions: | |
550 | ||
551 | texinfo-update-node \\[texinfo-update-node] | |
552 | texinfo-every-node-update \\[texinfo-every-node-update] | |
5ccb13ff | 553 | texinfo-sequential-node-update |
952d72ff RC |
554 | |
555 | texinfo-make-menu \\[texinfo-make-menu] | |
556 | texinfo-all-menus-update \\[texinfo-all-menus-update] | |
557 | texinfo-master-menu | |
558 | ||
559 | texinfo-indent-menu-description (column &optional region-p) | |
560 | ||
561 | The `texinfo-column-for-description' variable specifies the column to | |
5ccb13ff | 562 | which menu descriptions are indented. |
952d72ff RC |
563 | |
564 | Passed an argument (a prefix argument, if interactive), the | |
565 | `texinfo-update-node' and `texinfo-make-menu' functions do their jobs | |
566 | in the region. | |
567 | ||
d5aa8b02 | 568 | To use the updating commands, you must structure your Texinfo file |
952d72ff | 569 | hierarchically, such that each `@node' line, with the exception of the |
d5aa8b02 | 570 | Top node, is accompanied by some kind of section line, such as an |
952d72ff RC |
571 | `@chapter' or `@section' line. |
572 | ||
573 | If the file has a `top' node, it must be called `top' or `Top' and | |
574 | be the first node in the file. | |
