Subject: 27.2; make-manuals fails
Date: Sat, 24 Jul 2021 13:32:05 +0300

With the current emacs-27 branch of the Emacs repository, the
'make-manuals' script fails:

  eliz <at> fencepost:~/git/emacs/pretest$ ./admin/make-manuals
  Making manuals (slow)...
  Search failed: "<ul>"
  make-manuals: error running make-manuals

The error message doesn't help to understand in which file did the
search fail.

This could be due to using Texinfo 6.8: maybe the format of the
produced HTML have changed?

Let me know what other information I can provide to help resolve
this.  TIA.

It seems to work fine on Debian/bullseye:

[larsi <at> stories ~/src/emacs/emacs-27]$ ./admin/make-manuals 
Making manuals (slow)...
Adding compressed html files...
Making manual tarfiles...
Doing emacs...
...created emacs-manual-27.2.50.tar

Doing lispintro...
...created emacs-lispintro-27.2.50.tar
Doing misc...
...created emacs-misc-27.2.50.tar
Making refcards...

But this is with an older makeinfo:

[larsi <at> stories ~/src/emacs/emacs-27]$ makeinfo --version

Yes, with that version it worked for me as well, back when I updated
the manuals for the v27.2 release.

Nine months later, the script (admin/make-manuals) still doesn't work
with the latest Texinfo.  The end result is that right now, I'm unable
to update the Emacs on-line docs to the version that was released with
Emacs 28.1.  (And no, I don't want to downgrade my Texinfo just to do
that.)

I looked at the code in admin.el, and it seems to be trying to make
the produced HTML more pretty than what Texinfo produces.  While I'm
not objected to having prettier HTML manuals, this is not really our
job, and playing catch-up with the ever-changing HTML that comes from
Texinfo is a maintenance burden.  Moreover, the documentation of the
various "fixes" is minimal at best, and in many places nonexistent (in
the sense that there's no description of the original HTML, the
"improved" one, and the rationale for each "fix"); reverse-engineering
that from code which runs in batch mode is a non-trivial job,
especially since some "fixes" need old versions of Texinfo to be used
to even understand what they are doing.

So I don't think we should continue making these "fixes", unless
Someone™ steps forward and volunteers to keep maintaining this script,
keeping it up-to-date with the latest Texinfo developments, and
generally making sure the script is usable at all times.

I will wait for a day or two for someone to volunteer; failing that I
will remove most or all of the "fixes" from the script, so that it
works with the latest Texinfo, and so I could again refresh our
on-line documentation when needed.

TIA

I agree that Emacs should use the output that Texinfo generates.
If we have ideas for how the HTML output could be better,
let's suggest them to the Texinfo developers.

Removing the "fixes" is fine by me.

I eventually went with the minimal change: the function that fails due
to changes in how Texinfo 6.8 produces HTML was modified to skip the
problematic step of rewriting the TOC menu as a table (something that
wasn't possible to keep, because some of the information used for the
table is no longer there in the new HTML).  The rest of the "fixes" I
kept.

With that, I'm closing this bug.
