6.1.2 Writing an @node Line

The easiest and preferred way to write an @node line is to write @node at the beginning of a line and then the name of the node, like this:

@node node-name

If you are using GNU Emacs, you can use the update node commands provided by Texinfo mode to insert the names of the pointers; or (recommended), you can leave the pointers out of the Texinfo file and let makeinfo insert node pointers into the Info file it creates. (See Texinfo Mode, and makeinfo Pointer Creation.)

Alternatively, you can insert the ‘Next’, ‘Previous’, and ‘Up’ pointers yourself. If you do this, you may find it helpful to use the Texinfo mode keyboard command C-c C-c n. This command inserts ‘@node’ and a comment line listing the names of the pointers in their proper order. The comment line helps you keep track of which arguments are for which pointers. This comment line is especially useful if you are not familiar with Texinfo.

The template for a fully-written-out node line with ‘Next’, ‘Previous’, and ‘Up’ pointers looks like this:

@node node-name, next, previous, up

The node-name argument must be present, but the others are optional. If you wish to specify some but not others, just insert commas as needed, as in: ‘@node mynode,,,uppernode’. However, we recommend leaving off all the pointers and letting makeinfo determine them, as described above.

It’s, you can ignore @node lines altogether in your first draft and then use the texinfo-insert-node-lines command to create @node lines for you. However, we do not recommend this practice. It is better to name the node itself at the same time that you write a segment so you can easily make cross references. Useful cross references are an especially important feature of a good Texinfo manual.

After you have inserted an @node line, you should immediately write an @-command for the chapter or section and insert its name. Next (and this is important!), put in several index entries. Usually, you will find at least two and often as many as four or five ways of referring to the node in the index. Use them all. This will make it much easier for people to find the node.

Even when you explicitly specify all pointers, you cannot write the nodes in the Texinfo source file in an arbitrary order! Because formatters must process the file sequentially, irrespective of node pointers, you must write the nodes in the order you wish them to appear in the output. For Info format one can imagine that the order may not matter, but it matters for the other formats.
