28 | ;; Known bug: update commands fail to ignore @ignore. |
29 | ||
30 | ;; Summary: how to use the updating commands | |
31 | ||
32 | ;; The node and menu updating functions automatically | |
33 | ||
34 | ;; * insert missing `@node' lines, | |
35 | ;; * insert the `Next', `Previous' and `Up' pointers of a node, | |
d1f9f441 | 36 | ;; * insert or update the menu for a section, |
b578f267 EN |
37 | ;; * create a master menu for a Texinfo source file. |
38 | ;; | |
78897d3d | 39 | ;; With a prefix argument, the `texinfo-update-node' and |
b578f267 EN |
40 | ;; `texinfo-make-menu' functions do their jobs in the region. |
41 | ;; | |
42 | ;; In brief, the functions for creating or updating nodes and menus, are: | |
d1f9f441 RS |
43 | ;; |
44 | ;; texinfo-update-node (&optional beginning end) | |
45 | ;; texinfo-every-node-update () | |

b578f267 EN |
58 | |
59 | ;; Texinfo file structure | |
60 | ;; ---------------------- | |
61 | ||
62 | ;; To use the updating commands, you must structure your Texinfo file | |
63 | ;; hierarchically. Each `@node' line, with the exception of the top | |
64 | ;; node, must be accompanied by some kind of section line, such as an | |
65 | ;; `@chapter' or `@section' line. Each node-line/section-line | |
66 | ;; combination must look like this: | |
67 | ||
68 | ;; @node Lists and Tables, Cross References, Structuring, Top | |
69 | ;; @comment node-name, next, previous, up | |
70 | ;; @chapter Making Lists and Tables | |
71 | ||
72 | ;; or like this (without the `@comment' line): | |
73 | ||
74 | ;; @node Lists and Tables, Cross References, Structuring, Top | |
75 | ;; @chapter Making Lists and Tables | |
76 | ||
77 | ;; If the file has a `top' node, it must be called `top' or `Top' and | |
78 | ;; be the first node in the file. | |

104 | ;;; The menu making functions described in detail | |
7e1335cf | 105 | |
b578f267 EN |
106 | ;; The `texinfo-make-menu' function without an argument creates or |
107 | ;; updates a menu for the section encompassing the node that follows | |
108 | ;; point. With an argument, it makes or updates menus for the nodes | |
109 | ;; within or part of the marked region. | |
110 | ||
111 | ;; Whenever an existing menu is updated, the descriptions from | |
112 | ;; that menu are incorporated into the new menu. This is done by copying | |
113 | ;; descriptions from the existing menu to the entries in the new menu | |
114 | ;; that have the same node names. If the node names are different, the | |
115 | ;; descriptions are not copied to the new menu. | |
116 | ||
117 | ;; Menu entries that refer to other Info files are removed since they | |
118 | ;; are not a node within current buffer. This is a deficiency. | |
119 | ||
120 | ;; The `texinfo-all-menus-update' function runs `texinfo-make-menu' | |
121 | ;; on the whole buffer. | |
122 | ||
123 | ;; The `texinfo-master-menu' function creates an extended menu located | |
124 | ;; after the top node. (The file must have a top node.) The function | |
125 | ;; first updates all the regular menus in the buffer (incorporating the | |
126 | ;; descriptions from pre-existing menus), and then constructs a master | |
127 | ;; menu that includes every entry from every other menu. (However, the | |
128 | ;; function cannot update an already existing master menu; if one | |
129 | ;; exists, it must be removed before calling the function.) | |
130 | ||
131 | ;; The `texinfo-indent-menu-description' function indents every | |
132 | ;; description in the menu following point, to the specified column. | |
133 | ;; Non-nil argument (prefix, if interactive) means indent every | |
134 | ;; description in every menu in the region. This function does not | |
135 | ;; indent second and subsequent lines of a multi-line description. | |
136 | ||
137 | ;; The `texinfo-insert-node-lines' function inserts `@node' before the | |
138 | ;; `@chapter', `@section', and such like lines of a region in a Texinfo | |
139 | ;; file where the `@node' lines are missing. | |
d1f9f441 | 140 | ;; |
b578f267 EN |
141 | ;; With a non-nil argument (prefix, if interactive), the function not |
142 | ;; only inserts `@node' lines but also inserts the chapter or section | |
143 | ;; titles as the names of the corresponding nodes; and inserts titles | |
144 | ;; as node names in pre-existing `@node' lines that lack names. | |
d1f9f441 | 145 | ;; |
b578f267 EN |
146 | ;; Since node names should be more concise than section or chapter |
147 | ;; titles, node names so inserted will need to be edited manually. | |

1942 | With optional MAKE-MASTER-MENU argument (prefix arg, if interactive), | |

1943 | insert a master menu in OUTER-FILE in addition to creating or updating |
1944 | pointers in the first @node line in each included file and creating or | |
1945 | updating the `Top' level node pointers of the outer file. This does | |
1946 | not create or update other menus and pointers within the included | |
1947 | files. | |
7e1335cf RC |
1948 | |
1949 | With optional UPDATE-EVERYTHING argument (numeric prefix arg, if | |
1950 | interactive), update all the menus and all the `Next', `Previous', and | |
1951 | `Up' pointers of all the files included in OUTER-FILE before inserting | |
daa6abb8 RS |
1952 | a master menu in OUTER-FILE. Also, update the `Top' level node |
1953 | pointers of OUTER-FILE. | |

d1f9f441 | 1955 | Notes: |
7e1335cf RC |
1956 | |
1957 | * this command does NOT save any files--you must save the | |
1958 | outer file and any modified, included files. | |
1959 | ||
1960 | * except for the `Top' node, this command does NOT handle any | |
1961 | pre-existing nodes in the outer file; hence, indices must be | |
1962 | enclosed in an included file. | |
1963 | ||
1964 | Requirements: | |
1965 | ||
1966 | * each of the included files must contain exactly one highest | |
d1f9f441 | 1967 | hierarchical level node, |
7e1335cf RC |
1968 | * this highest node must be the first node in the included file, |
1969 | * each highest hierarchical level node must be of the same type. | |
1970 | ||
1971 | Thus, normally, each included file contains one, and only one, | |
1972 | chapter." | |
