Two Volume Cross References
|
||
===========================
|
||
|
||
18 March 1992
|
||
|
||
This enables you to create manuals in *two* volumes, with tables of
|
||
contents, cross references, and indices in each volume referring to
|
||
*both* volumes.
|
||
|
||
The procedure is tedious. However, the resulting two volumes are
|
||
conveniently organized. Each has an index of the whole two volumes.
|
||
Each volume starts with page 1. (I don't like multi-volume works
|
||
where each volume starts with a higher page number since I find it
|
||
harder to go to the right place in the volume.)
|
||
|
||
References to the same volume are just the page number; references to
|
||
the other volume are a volumne number (in Roman numerals) preceding
|
||
the page number.
|
||
|
||
For example, in Volume I:
|
||
|
||
list length ......... 90
|
||
list motion ......II:117
|
||
|
||
and in Volume II:
|
||
|
||
list length ....... I:90
|
||
list motion .........117
|
||
|
||
All other references and the table of contents work the same way. I
|
||
find this *very* helpful.
|
||
|
||
|
||
In brief: you run tex on a .texi file with
|
||
|
||
a. redefined @contents and @summarycontents inputting elisp-toc-2vol.toc file
|
||
b. redone .aux file
|
||
c. redone .fns file
|
||
|
||
|
||
Here are the steps in detail:
|
||
|
||
% tex vol1.texi
|
||
% texindex vol1.??
|
||
% tex vol1.texi
|
||
|
||
% tex vol2.texi
|
||
% texindex vol2.??
|
||
% tex vol2.texi
|
||
|
||
### Create .aux files with volume numbers for other volume.
|
||
|
||
% cp vol1.aux elisp1-aux
|
||
% cp vol2.aux elisp2-aux
|
||
|
||
% cp vol1.aux elisp1-aux-vol-number-added
|
||
% cp vol2.aux elisp2-aux-vol-number-added
|
||
|
||
on elisp1-aux-vol-number-added
|
||
(volume-aux-markup 1) see defun for volum-aux-markup below.
|
||
to create elisp1-aux-vol-number-added
|
||
|
||
on elisp2-aux-vol-number-added
|
||
(volume-aux-markup 2)
|
||
to create elisp2-aux-vol-number-added
|
||
|
||
insert elisp2-aux-vol-number-added into vol1.aux (append)
|
||
insert elisp1-aux-vol-number-added into vol2.aux (prepend)
|
||
|
||
(so you dont have to do it again)
|
||
% cp vol1.aux elisp1-aux-2vol-ready
|
||
% cp vol2.aux elisp2-aux-2vol-ready
|
||
|
||
|
||
### Create .fn files with volume numbers for other volume.
|
||
|
||
% cp vol1.fn elisp1-fn
|
||
% cp vol2.fn elisp2-fn
|
||
|
||
% cp vol1.fn elisp1-fn-vol-number-added
|
||
% cp vol2.fn elisp2-fn-vol-number-added
|
||
|
||
on elisp1-fn-vol-number-added
|
||
(volume-index-markup "I")
|
||
to create elisp1-fn-vol-number-added
|
||
|
||
on elisp2-fn-vol-number-added
|
||
(volume-index-markup "II")
|
||
to create elisp2-fn-vol-number-added
|
||
|
||
insert elisp2-fn-vol-number-added into vol1.fn: do following `cat'
|
||
insert elisp1-fn-vol-number-added into vol2.fn: do following `cat'
|
||
|
||
% cat elisp2-fn-vol-number-added >> vol1.fn
|
||
% cat elisp1-fn-vol-number-added >> vol2.fn
|
||
|
||
Be sure to handle special case entries by hand.
|
||
Be sure that .fn file has no blank lines.
|
||
|
||
% texindex vol1.fn
|
||
% texindex vol2.fn
|
||
|
||
(so you dont have to do it again)
|
||
% cp vol1.fns elisp1-fns-2vol-ready
|
||
% cp vol2.fns elisp2-fns-2vol-ready
|
||
|
||
### Create merged .toc file with volume number headings.
|
||
|
||
append vol2.toc to vol1.toc with following `cat'
|
||
|
||
% cat vol1.toc vol2.toc > elisp-toc-2vol.toc
|
||
|
||
and edit in Volume titles
|
||
|
||
\unnumbchapentry {Volume 1}{}
|
||
\unnumbchapentry {}{}
|
||
|
||
\unnumbchapentry {Index}{295}
|
||
\unnumbchapentry {}{}
|
||
\unnumbchapentry {Volume 2}{}
|
||
\unnumbchapentry {}{}
|
||
|
||
If you want to put in volume numbers for TOC, then do this:
|
||
Create volume specific .toc files with volume numbers in them.
|
||
|
||
% cp elisp-toc-2vol.toc elisp1-toc.toc
|
||
% cp elisp-toc-2vol.toc elisp2-toc.toc
|
||
|
||
Use keyboard macro to put I: in first half of elisp1-toc.toc and
|
||
II: in first half of elisp2-toc.toc
|
||
|
||
Copy the tocs to something you can remember more easily
|
||
|
||
% cp elisp2-toc.toc elisp1-toc-ready.toc
|
||
% cp elisp1-toc.toc elisp2-toc-ready.toc
|
||
|
||
Then, edit vol1.texi to input elisp1-toc-ready.toc
|
||
and vol2.texi to input elisp2-toc-ready.toc
|
||
|
||
|
||
### Now format the two volumes:
|
||
|
||
% cp elisp1-aux-2vol-ready vol1.aux
|
||
% cp elisp2-aux-2vol-ready vol2.aux
|
||
|
||
% tex vol1.texi
|
||
% tex vol2.texi
|
||
|
||
|
||
|
||
For every additional run:
|
||
|
||
### recopy aux files so the correct ones are read:
|
||
% cp elisp1-aux-2vol-ready vol1.aux
|
||
% cp elisp2-aux-2vol-ready vol2.aux
|
||
|
||
Do not run texindex. Then proper sorted index will stay.
|
||
else do: % cp elisp2-fns-2vol-ready vol2.fns
|
||
|
||
Do not change the .texi files; they will call the elisp-toc-2vol.toc file.
|
||
|
||
% tex vol1.texi
|
||
% tex vol2.texi

|

|

|
||
The steps:
|
||
|
||
1. Run TeX, texindex and TeX on file1.
|
||
2. Run TeX, texindex and TeX on file2.
|
||
|
||
3. Copy both .aux files into specially named files
|
||
|
||
4. In the case of the elisp ref manual,
|
||
|
||
copy the *unsorted* function index files into specially named files
|
||
(no other index used in elisp ref manual)
|
||
|
||
|
||
5. For aux files:
|
||
|
||
Run a function on the specially named .aux files to label each
|
||
entry according to volume. Save these files.
|
||
|
||
i.e., convert
|
||
'xrdef {Special-pg}{7} to 'xrdef {Special-pg}{7, vol.'tie1}
|
||
|
||
5a.Insert each specially named .aux file into the regular .aux file of
|
||
the other volume.
|
||
|
||
6. For index files:
|
||
|
||
Run a function on the specially named unsorted index files to label
|
||
each entry according to volume. Save these files.
|
||
|
||
6b.Insert each specially named marked unsorted index file into the
|
||
regular unsorted file of the other volume. Run texindex on this
|
||
|
||
7. Insert the other volumes .toc file into the .toc, edit, and rename to
|
||
elisp-toc-2vol.toc
|
||
|
||
7a. insert special @contents and @summarycontents defs into .texi files.
|
||
|
||
8. Run TeX on each .texi file.
|
||
|
||
================
|
||
|
||
|
||
|
||
Here is the discursive commentary:
|
||
|
||
I've been running some small test files, called test1.texi and
|
||
test2.texi. As far as I can see, if we run tex on the two test files,
|
||
tex creates a .aux for each that includes the names of all the nodes
|
||
in that file. The node names are used for cross references.
|
||
|
||
If you insert the .aux file for the second test file, test2.aux, into
|
||
the .aux file for the first test file, test1.aux, then when you next
|
||
run TeX on the first test file, test1.texi, the second volume cross
|
||
references are inserted.
|
||
|
||
You can edit the text of the cross reference in test2.aux to include
|
||
the volume number.
|
||
|
||
For example, you can take the following two lines from test1.texi and
|
||
insert them into test2.texi:
|
||
|
||
'xrdef {Special-pg}{7}
|
||
'xrdef {Special-snt}{Section'tie1.6}
|
||
|
||
You can re-edit this to show that the page is in volume 1:
|
||
|
||
'xrdef {Special-pg}{7, vol.'tie1}
|
||
'xrdef {Special-snt}{Section'tie1.6}
|
||
|
||
(The 'tie is a TeX special command to keep the number tied on one
|
||
line to the previous word. I don't know if it works after a period in
|
||
the "vol." but figure it is worth trying. {The ' is the @ of .aux files.}
|
||
Apparently 'tie is like the tilde in plain tex; in texinfo.tex, the
|
||
definition for 'tie is the following:
|
||
|
||
\def\tie{\penalty 10000\ } % Save plain tex definition of ~.
|
||
|
||
)
|
||
|
||
After running tex on the test2.texi file with the augmented test2.aux
|
||
file, you can see the following in the resulting DVI file:
|
||
|
||
See Section 1.6 [Special], page 7, vol. 1
|
||
|
||
Note that TeX rewrites the .aux file each time TeX is run, so after
|
||
running Tex using an .aux file augmented with the .aux file from the
|
||
other volume, the new .aux file will *lack* the other volumes cross
|
||
references. Save your augmented .aux file in some other name for
|
||
another run!
