D.9.1 Tagifying a File

Texinfo processors create tag tables automatically. The only exception arise when texinfo-format-buffer is called with a prefix, as C-u M-x texinfo-format-buffer, to create an non split Info file without a tag table (which can be useful in some cases for Info file validation, see Creating an Unsplit File and Adding a Tag Table). Adding a tag table is therefore more generally useful for manually written Info files.

To create a tag table for an nonsplit file, visit the Info file you wish to tagify and type:

M-x Info-tagify

(Note the uppercase ‘I’ in Info-tagify.) This creates an Info file with a tag table. A tag table is part of a well formed Info file (see Tag Files and Split Files). A tag table is also needed to validate or split the Info file.
