Table of contents in `xetex.pdf` unable to paginate

ToC unable to paginate	ToC paginates

Funny that you bring this up. Just today I made notes to compare the tables-of-contents of

• TeX: Tending to overflow on one page of ToC
• Metafont: Fits snuggly on one page of ToC, without \title{\MF}
• pdfTeX: Note generic “WEB output” on second page of ToC (see above)
• XeTeX: Overflow on one page (see above)
• HiTeX: CWEB, 3 pages of ToC at the end; indentations; short lines flush left; should be centered to match WEB conventions
• MetaPost: CWEB, added \title{\MP} at top of one page of ToC; full \pagewidth wide

in conjunction with pdfwebtocfront.tex in knuth-pdf.

It started only yesterday: https://tug.org/pipermail/metapost/2024-May/003564.html ;o)

The aim is to have a uniform layout for these ToCs including the \title{PROGRAM} on top.

After makeall -f "tex mf pdftex xetex hitex mp" -npt pdftex you can replace xetex.toc with pdftex.toc and rerun xetex xetex to get a two-page ToC. I have no clue what's different in the various preambles.

See also issue #25 for a broader picture.

makeall -f "tex mf pdftex xetex hitex mp" -npt pdftex only compiled tex.tex for me. I use a non-full TeX Live installation. Would that matter?

It seems the ToC in tex.pdf has a similar problem (maybe that's intentional behavior since there's no "Overfull \vbox" in loading CONTENTS.tex):

xetex.pdf has more chapters so the problem is more visually obvious, as the last ToC entry "55. Index" is missing.

Since xewebmac.tex loads webmac.tex (if \botofcontents is undefined), the difference may come from the differences between pdfwebmac.tex and webmac.tex.

In order to use the makeall script you need the source tree for TeX Live. (If you want to commit code, submit patches to tex-k@tug.org.)

Yes, TeX's ToC is tight. It runs to two pages for the TeX Live version.

Since xewebmac.tex loads webmac.tex (if \botofcontents is undefined), the difference may come from the differences between pdfwebmac.tex and webmac.tex.

If you run makeall -f tex -npt pdftex, the outdated macros xewebmac.tex and pdfwebmac.tex are not used, but the modern pwebmac.tex(and that's the only version of "PDF macros for WEB" I use).

Another facet of this issue is that tex-changes.pdf has a two-page ToC and the main code starts on page 4 instead of 3. Will have to adapt pdfwebtocfront.tex.

[ascherer]

The most recent pdfwebtocfront.tex addresses this issue: \pdfpageheight is increased by half an inch for the long programs (TeX, Metafont, pdfTeX, and XeTeX). Also the default header title “WEB output” is replaced with “Table of Contents” on the second page of the ToC.

Samples for the upcoming knuth-pdf package can be studied in this release.
