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,
|
|
36 ; * insert or update the menu for a section,
|
|
37 ; * create a master menu for a Texinfo source file.
|
|
38 ;
|
|
39 ; Passed an argument, the `texinfo-update-node' and
|
|
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:
|
|
43 ;
|
|
44 ; texinfo-update-node (&optional region-p)
|
|
45 ; texinfo-every-node-update ()
|
|
46 ; texinfo-sequential-node-update (&optional region-p)
|
|
47 ;
|
|
48 ; texinfo-make-menu (&optional region-p)
|
|
49 ; texinfo-all-menus-update ()
|
|
50 ; texinfo-master-menu ()
|
|
51 ;
|
|
52 ; texinfo-insert-node-lines (&optional title-p)
|
|
53 ;
|
|
54 ; texinfo-indent-menu-description (column &optional region-p)
|
|
55
|
|
56 ; The `texinfo-column-for-description' variable specifies the column to
|
|
57 ; which menu descriptions are indented.
|
|
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.
|
|
79
|
|
80
|
|
81 ;;; The update node functions described in detail
|
|
82
|
|
83 ; The `texinfo-update-node' function without an argument inserts
|
|
84 ; the correct next, previous and up pointers for the node in which
|
|
85 ; point is located (i.e., for the node preceding point).
|
|
86
|
|
87 ; With an argument, the `texinfo-update-node' function inserts the
|
|
88 ; correct next, previous and up pointers for the nodes inside the
|
|
89 ; region.
|
|
90
|
|
91 ; It does not matter whether the `@node' line has pre-existing
|
|
92 ; `Next', `Previous', or `Up' pointers in it. They are removed.
|
|
93
|
|
94 ; The `texinfo-every-node-update' function runs `texinfo-update-node'
|
|
95 ; on the whole buffer.
|
|
96
|
|
97 ; The `texinfo-sequential-node-update' function inserts the
|
|
98 ; immediately following and preceding node into the `Next' or
|
|
99 ; `Previous' pointers regardless of their hierarchical level. This is
|
|
100 ; only useful for certain kinds of text, like a novel, which you go
|
|
101 ; through sequentially.
|
|
102
|
|
103
|
|
104 ;;; The menu making functions described in detail
|
|
105
|
|
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.
|
|
140 ;
|
|
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.
|
|
145 ;
|
|
146 ; Since node names should be more concise than section or chapter
|
|
147 ; titles, node names so inserted will need to be edited manually.

|

765 lower level menus, in order. This way, an inquirer can go

766 directly to a particular node if he or she is searching for
|
|
767 specific information.

1939 Notes:
|
|
1940
|
|
1941 * this command does NOT save any files--you must save the
|
|
1942 outer file and any modified, included files.
|
|
1943
|
|
1944 * except for the `Top' node, this command does NOT handle any
|
|
1945 pre-existing nodes in the outer file; hence, indices must be
|
|
1946 enclosed in an included file.
|
|
1947
|
|
1948 Requirements:
|
|
1949
|
|
1950 * each of the included files must contain exactly one highest
|
|
1951 hierarchical level node,
|
|
1952 * this highest node must be the first node in the included file,
|
|
1953 * each highest hierarchical level node must be of the same type.
|
|
1954
|
|
1955 Thus, normally, each included file contains one, and only one,
