You can do the basic formatting of a Texinfo file with the shell
tex followed by the name of the Texinfo file. For
TeX will produce a DVI file as well as several auxiliary files containing information for indices, cross-references, etc. The DVI file (for DeVice Independent file) can be printed on virtually any device, perhaps after a further conversion (see the previous section).
tex formatting command itself does not sort the indices; it
writes an output file of unsorted index data. To generate a printed
index after running the
tex command, you first need a sorted
index to work from. The
texindex command sorts indices.
texi2dvi, described in the previous section, runs
texindex as necessary.)
tex outputs unsorted index files under names following a
standard convention: the name of your main input file with any
‘.texi’ or similar extension replaced by the two letter index
name. For example, the raw index output files for the input file
foo.texi would be, by default, foo.cp, foo.vr,
foo.fn, foo.tp, foo.pg and foo.ky. Those
are exactly the arguments to give to
Instead of specifying all the unsorted index file names explicitly, it’s typical to use ‘??’ as shell wildcards and give the command in this form:
This command will run
texindex on all the unsorted index files,
including any two letter indices that you have defined yourself using
@defcodeindex. You can safely run
‘texindex foo.??’ even if there are files with two letter
extensions that are not index files, such as ‘foo.el’. The
texindex command reports but otherwise ignores such files.
For each file specified,
texindex generates a sorted index file
whose name is made by appending ‘s’ to the input file name; for
example, foo.cps is made from foo.cp. The
@printindex command looks for a file with that name
(see Printing Indices & Menus). TeX does not read the raw
index output file, and
texindex does not alter it.
After you have sorted the indices, you need to rerun
tex on the
Texinfo file. This regenerates the output file, this time with
up-to-date index entries.
Finally, you may need to run
tex one more time, to get the page
numbers in the cross-references correct.
To summarize, this is a five step process. (Alternatively, it’s a
one-step process: run
texi2dvi; see the previous section.)
texon your Texinfo file. This generates a DVI file (with undefined cross-references and no indices), and the raw index files (with two letter extensions).
texindexon the raw index files. This creates the corresponding sorted index files (with three letter extensions).
texagain on your Texinfo file. This regenerates the DVI file, this time with indices and defined cross-references, but with page numbers for the cross-references from the previous run, generally incorrect.
texone last time. This time the correct page numbers are written for the cross-references.
