[PATCH 0/7] Documentation fixes for v2.27.0-rc0

[Martin Ågren]

I've gone through

  doc-diff v2.26.0 v2.27.0-rc0

and identified a few misrenderings. Here's my attempt to address them.

Working on this, I also got to look at the new features in the upcoming
release from another angle -- looking good!

  git-bugreport.txt: fix reference to strftime(3)

[PATCH 1/7] date-formats.txt: fix list continuation

[Martin Ågren]

The blank line before the lone "+" means it isn't detected as a list
continuation, but instead renders literally, at least with AsciiDoc.
Drop the empty line and, while at it, add a closing period to the
preceding paragraph.

[PATCH 4/7] git-commit-graph.txt: fix list rendering

[Martin Ågren]

The first list item follows immediately on the paragraph where we
introduce the list. This makes the "*" render literally as part of one
huge paragraph. (With AsciiDoc, everything is fine after that, but with
Asciidoctor, we get some minor follow-on errors.) Add an empty line --
with a list continuation ("+") -- to make the first list item render ok.

[PATCH 7/7] rev-list-options.txt

[Martin Ågren]

The explanation of the `--show-pulls` option added in commit 8d049e182e
("revision: --show-pulls adds helpful merges", 2020-04-10) consists of
several paragraphs and we use "+" throughout to tie them together in one
long chain of list continuations. Only thing is, we're not in any kind
of list, so these pluses end up being rendered literally.

The preceding few paragraphs describe `--ancestry-path` and there we
*do* have a list, since we've started one with `--ancestry-path::`. But
we don't have a similar list running here. We could tie all our
paragraphs from 8d049e182e to that list, but that doesn't make much
sense: We aim to describe another option entirely.

We could start a new list item:

 --show-pulls:
    Before discussing another option, `--show-pulls`, we need to
    create a new example history.
 +
    ...

That reads somewhat awkwardly to me. Not to mention that the chain of
paragraphs that follows is fairly long, introducing a new example
history and discussing it in quite some detail. Let's make this run
along without any kind of indentation. It effectively means that we're
treating "Before discussing..." as a paragraph on the same level as
"There is another simplification mode available:" which precedes the
`--ancestry-path::` list.

If we really want a `--show-pulls::` list somewhere, we could perhaps
let it begin around "The `--show-pulls` option helps with both of these
issues ..." further down. But for now, let's just focus on getting rid
of those literal pluses.

 A common problem users face when looking at simplified history is that a

 Here, the merge commits `O` and `P` contribute extra noise, as they did
 not actually contribute a change to `file.txt`. They only merged a topic

 When using the `--simplify-merges` option, the commits `O` and `P`
 disappear from the results. This is because the rewritten second parents
 of `O` and `P` are reachable from their first parents. Those edges are
 removed and then the commits look like single-parent commits that are
 TREESAME to their parent. This also happens to the commit `N`, resulting

Not even sure of that: strftime is not an internal manpage, so for html
target, we will end up with a hyperlink to an non-existing file
strftime.html. So I would keep it as simple text.

That's a good point. I don't use the HTML versions myself, so I haven't
thought about the *linking* nature much -- I just see the formatting.
But you're right. Grepping around, we only seem to use linkgit to refer
to our own docs. So this should probably just be "strftime(3)" as you
say.

I think the way you adjusted the preamble is good. It matches this prior
work before --ancestry-path:

	Finally, there is a fifth simplification mode available:

	--ancestry-path::
		(description)
	+
	(example)
	+
	...

And you're right, we do drop the "--show-pulls::" itemization. Will that
make it hard to link to that exact option? Probably.

What about the fixup below, to create this list item?

Hi Stolee,

(I realize now that the subject/oneliner of this patch is completely
broken. Hmpf.)

I considered creating the list item, but like you, I figured it required
more surgery to the text than I felt like pursuing. Thanks for making a
concrete suggestion.

    rev-list-options.txt: start a list for `show-pulls`

    The explanation of the `--show-pulls` option added in commit 8d049e182e
    ("revision: --show-pulls adds helpful merges", 2020-04-10) consists of
    several paragraphs and we use "+" throughout to tie them together in one
    long chain of list continuations. Only thing is, we're not in any kind
    of list, so these pluses end up being rendered literally.

    The preceding few paragraphs describe `--ancestry-path` and there we
    *do* have a list, since we've started one with `--ancestry-path::`. In
    fact, we have several such lists for all the various history-simplifying
    options we're discussing earlier in this file.

    Thus, we're missing a list both from a consistency point of view and
    from a practical rendering standpoint.

    Let's start a list for `--show-pulls` where we start actually discussing
    the option, and keep the paragraphs preceding it out of that list. That
    is, drop all those pluses before the new list we're adding here.

A long weekend offline passes and it's already a week later...

Here is my original patch 7/7 plus Stolee's fixup, with the rephrased
commit message from upthread. I've tried to test it from all angles I
can think of -- AsciiDoc/Asciidoctor, man/html, doc-diff, ... It should
be low-risk and does avoid beginning ~20 paragraphs with a literal "+"
in the rendered docs for this new option.

 A common problem users face when looking at simplified history is that a

 Here, the merge commits `O` and `P` contribute extra noise, as they did

 When using the `--simplify-merges` option, the commits `O` and `P`

 TREESAME to their parent. This also happens to the commit `N`, resulting

I like how you found a way to add the list item without needing to make a
huge shift in the surrounding prose. LGTM.

The way the "History Simplification" section is organized is
somewhat peculiar in that it begins with a short list of what's
available, followed by mixture of detailed explanation in prose.  I
agree with you two that the result of this patch fits very well to
the surrounding text.

But rewording it is another topic totally different from "we should
render this section correctly" fix we have here, and should be done
(if it needs to be done in the first place) separately after this
change lands.

Thanks, both.

I guess the 'as if it "pulled" the change from another branch' sentence
is literally talking about the "git pull" command, as opposed to the
"git merge" command, or creating the merge upon completion of a pull request
on a Git service (which is almost always using libgit2 to generate a merge
commit).

Perhaps there is no semantic difference between "pulling" and "merging"
and then this could be reworded to be less awkward.

Actually, I didn't see how to do it, but luckily, you did. [1] So I take
this to mean that even on re-reading your proposed text some time later,
you like it. ;-)

Agreed on the awkwardness as it stands (before or after this proposed
patch). I don't have any concrete thoughts to offer though.
