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 ================================================================ @c ================================================================ @tex % Special @contents command % This inputs fixed up table of contents file rather than create new one. \global\def\contents{% \startcontents{Table of Contents}% \input elisp-toc-2vol.toc \endgroup \vfill \eject } % Special @summarycontents command % This inputs fixed up table of contents file rather than create new one. \outer\def\summarycontents{% \startcontents{Short Contents}% % \let\chapentry = \shortchapentry \let\unnumbchapentry = \shortunnumberedentry % We want a true roman here for the page numbers. \secfonts \let\rm=\shortcontrm \let\bf=\shortcontbf \let\sl=\shortcontsl \rm \advance\baselineskip by 1pt % Open it up a little. \def\secentry ##1##2##3##4{} \def\unnumbsecentry ##1##2{} \def\subsecentry ##1##2##3##4##5{} \def\unnumbsubsecentry ##1##2{} \def\subsubsecentry ##1##2##3##4##5##6{} \def\unnumbsubsubsecentry ##1##2{} \input elisp-toc-2vol.toc \endgroup \vfill \eject } @end tex @c ================================================================ ================================================================ (defun volume-aux-markup (arg) "Append vol.

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! `
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
