Here is a copy of the diagram shown earlier that illustrates a Texinfo file with three chapters, each of which contains two sections.
Note that the "root" is at the top of the diagram and the "leaves" are at the bottom. This is how such a diagram is drawn conventionally; it illustrates an upside-down tree. For this reason, the root node is called the `Top' node, and `Up' node pointers carry you closer to the root.
Top | ------------------------------------- | | | Chapter 1 Chapter 2 Chapter 3 | | | -------- -------- -------- | | | | | | Section Section Section Section Section Section 1.1 1.2 2.1 2.2 3.1 3.2
Write the beginning of the node for Chapter 2 like this:
@node Chapter 2, Chapter 3, Chapter 1, top @comment node-name, next, previous, up
@node line says that the name of this node is "Chapter 2", the
name of the `Next' node is "Chapter 3", the name of the `Previous'
node is "Chapter 1", and the name of the `Up' node is "Top".
Please Note: `Next' refers to the next node at the same hierarchical level in the manual, not necessarily to the next node within the Texinfo file. In the Texinfo file, the subsequent node may be at a lower level--a section-level node may follow a chapter-level node, and a subsection-level node may follow a section-level node. `Next' and `Previous' refer to nodes at the same hierarchical level. (The `Top' node contains the exception to this rule. Since the `Top' node is the only node at that level, `Next' refers to the first following node, which is almost always a chapter or chapter-level node.)
To go to Sections 2.1 and 2.2 using Info, you need a menu inside Chapter 2. (See section Menus.) You would write the menu just before the beginning of Section 2.1, like this:
@menu * Sect. 2.1:: Description of this section. * Sect. 2.2:: @end menu
Write the node for Sect. 2.1 like this:
@node Sect. 2.1, Sect. 2.2, Chapter 2, Chapter 2 @comment node-name, next, previous, up
In Info format, the `Next' and `Previous' pointers of a node usually lead to other nodes at the same level--from chapter to chapter or from section to section (sometimes, as shown, the `Previous' pointer points up); an `Up' pointer usually leads to a node at the level above (closer to the `Top' node); and a `Menu' leads to nodes at a level below (closer to `leaves'). (A cross reference can point to a node at any level; see section Cross References.)
@node command and a chapter structuring command are
used in sequence, along with indexing commands. (You may follow the
@node line with a comment line that reminds you which pointer is
Here is the beginning of the chapter in this manual called "Ending a
Texinfo File". This shows an
@node line followed by a comment
@chapter line, and then by indexing lines.
@node Ending a File, Structuring, Beginning a File, Top @comment node-name, next, previous, up @chapter Ending a Texinfo File @cindex Ending a Texinfo file @cindex Texinfo file ending @cindex File ending
