<p dir="auto">This trace output is admittedly not “user-friendly” in appearance, but after all it comes from deep inside TeX‘s bowels where things have been reduced to numeric calculations. You can learn to read it with a little practice, but you won‘t need to do so very often unless you need to plunge into page-breaking for special applications. Here‘s what it means: The first line, which starts with ‘<code class="notranslate">%%</code>’, is written when the first box or insertion enters the current page list; it shows the “goal height” and the “max depth” that will be used for that page (namely, the current values of <code class="notranslate">\vsize</code> and <code class="notranslate">\maxdepth</code>). In the present manual [referring to <em>The TeXBook</em> —Kevin] we have <code class="notranslate">\vsize=44pc</code> and <code class="notranslate">\maxdepth=2.2pt</code>; dimensions in the log file are always displayed in points. The subsequent lines, which start with a single ‘<code class="notranslate">%</code>’, are written whenever a legal breakpoint is being moved from the list of recent contributions to the current page list. Every <code class="notranslate">%</code> line shows <em>t</em>, which is the total height so far if a page break were to occur, and <em>g</em>, which is the goal height; in this example <em>g</em> stays fixed at 528 pt, but <em>g</em> would have decreased if insertions such as footnotes had occurred on the page. The values of <em>t</em> are steadily increasing from 10 to 22 to 34, etc.; baselines are 12pt apart at the top of the page and 11pt apart at the bottom (where material is set in nine-point type). We are essentially seeing one <code class="notranslate">%</code> line per hbox of text being placed on the current page. However, the <code class="notranslate">%</code> lines are generated by the penalty or glue items that follow the hboxes, not by the boxes themselves. Each <code class="notranslate">%</code> line shows also the badness <em>b</em>, the penalty <em>p</em>, and the cost <em>c</em> associated with a breakpoint; if this cost is the best so far, it is marked with a ‘<code class="notranslate">#</code>’ sign, meaning that “this breakpoint will be used for the current page if nothing better comes along.” Notice that the first 40 or so breaks all have <em>b</em> = 10000, since they are so bad that TeX considers them indistinguishable; in such cases <em>c</em> = 100000, so TeX simply accumulates material until the page is full enough to have <em>b</em> &lt; 10000. A penalty of 150 reflects the <code class="notranslate">\clubpenalty</code> or the <code class="notranslate">\widowpenalty</code> that was inserted as described in Chapter 14. The three lines that say <code class="notranslate">p=-100</code> are the breakpoints between “dangerous bend” paragraphs; these came from <code class="notranslate">\medbreak</code> commands. The notation <code class="notranslate">b=*</code> and <code class="notranslate">c=*</code> on the final line means that <em>b</em> and <em>c</em> are infinite; the total height of 553 pt cannot be reduced to 528 pt by shrinking the available glue. Therefore the page is ejected at the best previous place, which turns out to be a pretty good break: <code class="notranslate">b=5</code> and <code class="notranslate">p=-100</code> yield a net cost of −95.</p>

<p dir="auto">It appears that a "listings" environment has a page break penalty of -50 before and after it, which is (in principle) a good idea: Breaking before a listing is certainly better than breaking in the middle of it. However, that somehow seems to override / cancel the general setting "do not break after a heading".</p>

<ul dir="auto">
<li>A section heading sets \if@nobreak to \iftrue and sets \everypar to something that indicates an infinite \clubpenalty. Also, \everypar is defined to reset itself to empty and to set \if@nobreak back to \iffalse. This prevents a lone line of text after a heading for sure, because \everypar is executed for each paragraph (due to the reset, extra stuff is only effective for the first paragraph after a heading).</li>
<li>A listing immediately after a section heading seems to reset \everypar, but does not reset \if@nobreak, leaving the setting from the heading turned on indefinitely, although it was supposed to be once-only for the next paragraph (i.e. the first line of the listing). And when the index machinery (via \indexlibrary) asks about the setting some time later, it yields a vertical \nobreak in the middle of plain text. Presumably, the index package wants to retain \nobreak after section headings if people use index commands between the section heading and the first text paragraph of a section.</li>
</ul>

Please see the large green diff in styles.tex for the specific changes vs. the stock package, each marked by a TeX comment.</p>
<p dir="auto">To summarize the issue with \everypar: The section heading sets \everypar to "something", but the listings package cavalierly ignores the previous value of \everypar and sets its own value. That's not good. (LaTeX doesn't seem to have infrastructure for an extensible and flexible mechanism for \everypar that could be used by several clients independently. Poster-child global variable problem, I'd say.)</p>

Except that there's only "add-to-hook", not "remove-from-hook" to perform the \everypar reset. (Nothing an additional level of indirection can't fix.) However, that approach means copying some details of "memoir" into our code, which is probably as bad as copying some details of "listings" into our code. And we need to massage "listings" even more to detect empty lines and semicolons and introduce an attractive page break there.</p>

<ul dir="auto">
<li>In listings, detect semicolons and closing braces and prefer breaking after these. Don't break before a lone closing brace in a line (should make <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/users/zygoloid/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/zygoloid">@zygoloid</a> happy).<br>
This has some good overall effects, because it keeps "<code class="notranslate">struct X {</code>", "<code class="notranslate">namespace N {</code>", and "<code class="notranslate">private:</code>" together with the stuff that follows. Also, I haven't yet found a header synopsis where a single declaration would be torn across pages.</li>
</ul>
<p dir="auto">At this time, we still prefer breaking inside an itemdecl (even when not after a semicolon) vs. breaking between the itemdecl and the itemdescr. (See [alg.remove] for an example.) We can fine-tune this by increasing the "midpenalty" in itemdecl.</p>

<p dir="auto">At this time, we still prefer breaking inside an itemdecl (even when not after a semicolon) vs. breaking between the itemdecl and the itemdescr.</p>
</blockquote>
<p dir="auto">If this means that we prefer breaking between two declarations in an itemdecl over breaking between itemdecl and itemdescr, then I think that's the right thing, even if in bad cases we end up breaking between decl and descr.</p>
<p dir="auto">I don't expect this work to remove the need for manual vertical whitespace fixes for C++20, but it sounds like it should at least make them substantially easier, and make the working drafts more readable.</p>
<p dir="auto">How confident are you that this change doesn't introduce significant formatting regressions (very ugly pagebreaks, text outside the bounds of the textblock, etc)? Given that we only have a couple of days before the mailing deadline, I'm trying to determine whether we should merge this now, or merge it after we cut the pre-meeting working draft.</p>

I'm not happy with copy-pasting chunks of listings, but if only the alternative is copy-pasting chunks of memoir, I don't have a strong preference. (Ideally I'd like to minimize the amount of delta we introduce in this way, though.)</p>

<ul dir="auto">
<li>Orphaned headings before requirement tables in library section (pre-existing problem; maybe it pops up now because the pagination is different). Can be fixed using \needspace as a separate effort, if desired.</li>
<li>There's a noticeable amount of whitespace at the end of some pages, e.g. before [support.initlist.access], because we have a section heading, a one-line itemdecl, and a two-line itemdescr, which can't be broken anywhere (breaking after a heading ("orphaned heading") is never even considered; we seriously penalize breaking after an itemdecl; and breaking the two-line itemdescr would create a club and a widow). This seems "as expected", though.</li>
<li>The way we tend to break between an itemdescr and the following itemdecl is really nice and helps a lot in the library section.</li>
<li>I have not seen text running over the bottom or similar. We can certainly discuss about 10 individual page breaks where best to break if done manually, but that's better left to just before C++20 ships. Looking at the <code class="notranslate">\newpage</code> counts on the C++17 branch, we seem to get an order of magnitude better.</li>
</ul>

It's a known problem with LaTeX. Packages are always stomping on each other, redefining the same macros (sometimes politely, sometimes less so), and vying for control over what hooks are available.</p>
<p dir="auto">One thing I would recommend is to use <code class="notranslate">\CheckCommand</code> to alert us if the macro we copied has changed from when we copied it (e.g., was updated when the package or class was upgraded or when a new package has been loaded that also modifies the macro). That we don't end up perpetuating bugs or preventing newer features of the package/class from working indefinitely.</p>

<p dir="auto">In fact, I've only found one page break I don't like so far: in [util.sharedptr.shared.const]'s itemdecl between p8 and p9, we put the first three declarations on the bottom of one page (with a large section of empty whitespace below them), and put the fourth declaration and the itemdescr at the top of the next page. The net result looks pretty silly.</p>
<p dir="auto">I think it would be preferable to keep the itemdecl together here, and break the 3-line p9 across the page. (Leaving an orphaned single line is bad, but the current formatting is worse.) I wonder if we can increase the penalty for breaking within an itemdecl to cause that to happen.</p>
