[PATCH 0/8] Documentation: XSLT/asciidoc.conf cleanup; tty literals

[PATCH 0/8] Documentation: XSLT/asciidoc.conf cleanup; tty literals

[Chris Johnsen]

I had a go at wrangling with the documentation generation tools
to fix a couple of issues that I had noticed.

First, I could never get reasonable output for generated
manpages.  I have asciidoc 8.3.1 and docbook-xsl 1.74.0 on my
system. They chew through the documentation OK, but I was never
sure which flags I should use with them.

ASCIIDOC8 never seemed to do much (I was probably not looking in
the right places), but I decided to leave it enabled since it is
entirely outside the scope of the git code/configuration.

The other variable was DOCBOOK_XSL_172, and no matter which way I
turned it, I always got flawed output. If I set it, I would get
funky characters in the callout sections. If I unset it, I would
get ".ft C" and ".ft" bracketing literal blocks.

Second, the inline literal text of both the official and my
generated manpages was indistinguishable from the surrounding
text when viewing manpages in a terminal. It turns out the
official manpages end up with no markup for inline literal
text. The ones I generated did have some markup, but it was
flagged as monospace text, which is not all that distinguishable
from the normal, roman text when viewing through a terminal.

So I set about trying to solve these problems along with the
meta-problem of code duplication between callouts.xsl and
manpage-1.72.xsl.

The following series is my attempt to

  eliminate the XSLT code duplication,

  tease apart the uses of the "1.72" label that apply only to
    docbook-xsl 1.72 and those that also apply to some other
    versions of docbook-xsl,

  unify some of the items that look like they were applied to
    only one side of various "1.72" configurations but still
    seemed applicable to the other,

  fix a mostly unrelated, small, latent bug in asciidoc.conf,

  and provide an option to differentiate inline literal text when
    viewed on a terminal.

[PATCH 1/8] Documentation: move callouts.xsl to manpage-{base,normal}.xsl

[Chris Johnsen]

Each of manpage-base.xsl and manpage-normal.xsl gets a copy of
the contents of callouts.xsl and the original is removed. The
Makefile is adjusted to refer to manpage-normal.xsl instead of
callouts.xsl. manpage-base.xsl will be later made into a common
base for -normal and -1.72.

Testing done with asciidoc 8.3.1 and docbook-xsl 1.74.0.

This duplication is in preparation for refactoring. It should
make it easier to keep track of the source of the various XSL
constructs while reviewing.

[PATCH 2/8] Documentation: use parametrized manpage-base.xsl with manpage-{1.72,normal}.xsl

[Chris Johnsen]

Parametrize the backslash and dot characters that are used to
generate roff control sequences in manpage-base.xsl.

The code reuse is achieved through the Makefile's invocation of
xmlto, where the -base and either -normal or -1.72 "modules" are
combined to render the manpages. xmlto's module system works by
constructing a temporary XSLT stylesheet that <xsl:import>s the
main docbook-xsl file and then <xsl:includes> all the modules
specified on the command line. Because of a technical detail of
XSLT (<http://www.w3.org/TR/xslt#top-level-variables>), we need
to be sure that each param is bound only once across all the
modules that will be used in a single xmlto invocation.

The initial implementation used an explicit <xsl:import> to
achieve a layering effect that allowed default param values and
override param values. That worked fine until one of the final
features of this series needed to supply override param values
via  the --stringparam option of xmlto. It turns out that
--stringparam is broken in all but the pre-release version of
xmlto. Since xmlto is a shell script the patch to fix it is
simple enough, but I instead opted to use xmlto's "module"
functionality to achieve the XSLT stylesheet reuse.

Testing done with asciidoc 8.3.1 and docbook-xsl 1.74.0.

[PATCH 3/8] Documentation: rename docbook-xsl-172 attribute to git-asciidoc-no-roff

[Chris Johnsen]

It seems that the ability to use raw roff codes in asciidoc.conf
was eliminated by docbook-xsl 1.72.0 _and later_. Unlike the
1.72.0-specific XSLT problem, this behavior was not reverted in
later releases.

This patch aims to make it clear that the affected asciidoc
attribute (flag) can be reasonably used with docbook-xsl versions
other than 1.72.0.

Also, document which make variables should be set for various
versions of asciidoc and docbook-xsl.

Testing done with asciidoc 8.3.1 and docbook-xsl 1.74.0.

This has no behavior changes for existing uses (make
DOCBOOK_XSL_172=Yes), but it enables new functionality
(ASCIIDOC_NO_ROFF=Yes) by divorcing the roff-avoiding parts of
asciidoc.conf from the label docbook-xsl-172.

I like the idea of including "tested with asciidoc/docbook-xsl
version info" in the commit message. It would have been very
helpful if all the previous commits to the core documentation
generation infrastructure carried such information.

[PATCH 4/8] Documentation: move quieting params into manpage-base.xsl

[Chris Johnsen]

Move a couple of XSL parameters that act to silence
informational/warning messages generated when running xmlto from
manpage-1.72.xsl to manpage-base.xsl.

Since unused parameters are silently ignored, there is no problem
if some version of docbook-xsl does not know about these
parameters. The only problem might be if a version of docbook-xsl
uses the parameters for alternate functionality. Since both
parameters have fairly specific names such a situation is
unlikely.

Testing done with asciidoc 8.3.1 and docbook-xsl 1.74.0.

I am not sure why these were only in the -1.72 variant. They
should probably be in -base (done by this patch) or in neither
variant. If there is a good reason for having it only in -1.72,
this patch can be dropped entirely, the rest do not depend on it.

versions.

I do not know why this was only in the non-1.72 variant. Maybe
docbook-xsl 1.72.0 did not need it. But it does not seem like it
would hurt to push it into the shared XSLT. As before, if there
is a good reason to keep it out of the -1.72 processing, then
just drop this patch, none of the rest depend on it.

[PATCH 6/8] Documentation: asciidoc.conf: always use <literallayout> for [blocktext]

[Chris Johnsen]

Make the docbook-xsl-no-raw-roff variant match the
no-docbook-xsl-no-raw-roff variant in terms of which XML tag is
used to wrap listing block text (delimited with lines of dashes).

e920b56 (Tweak asciidoc output to work with broken docbook-xsl,
2006-03-05) says docbook-xsl 1.68 needs <literallayout>. This
<screen> usages was in the old, 1.72-only section. But since it
is now the "roff-less" section, it probably makes sense to make it
symmetric with the "roff-ful" section.

Testing done with asciidoc 8.3.1 and docbook-xsl 1.74.0.

Signed-off-by: Chris Johnsen <chris_johnsen@pobox.com>

This is another cleanup to make the two conditional sections more
symmetric.

The only large, remaining asymmetry in the asciidoc.conf
roff/non-roff parts is the [verseblock] in the non-roff
section. Should [verseblock] be pulled out of the
roff-conditional parts?  Should a [verseblock] section be added
to the roff-using part?

[PATCH 8/8] Documentation: option to render literal text as bold for manpages

[Chris Johnsen]

This allows manpages viewed on a tty to render inline literal
text in a manner that is distinct from the surrounding text.

Testing done with asciidoc 8.3.1 and docbook-xsl 1.74.0.

Signed-off-by: Chris Johnsen <chris_johnsen@pobox.com>

---

Since dobcook-xsl 1.74.0 seems to introduce using a monospace
font for literal text (asciidoc backticks), this patch may not be
so important for end users that can install their own
docbook-xsl.

But this patch, or something like it, might be useful for
introducing some kind of typesetting for literal text in the
official manpages (since it would not require upgrading
docbook-xsl). It could probably even be changed/extended to
provide monospacing without using a new docbook-xsl.

The functionality is optional and defaults to "off", so there
probably is not too much harm in including it, even if it is not
used for the official manpages.

This is definitely a good change, though it would also be fine to
actually munge the contents in the same patch rather than duplicate them
(i.e., actually _split_ callouts.xsl instead of copying it to two
places).

I think it would have been much easier to read, though, by turning on
rename detection in format-patch (i.e., "-M"). That yields:

Hmm. I'm not sure I understood all of the issues you ran into that you
mentioned in the commit message (but trust me, having tried to do
anything with docbook, I can sympathize with the frustration you
probably felt), so maybe I am missing something. But is it not possible

Great, this looks like a definite improvement. Should we be respecting
more DOCBOOK_XSL_* variables than just 172, then? I.e.,:

DOCBOOK_XSL_173, etc?

I don't know that we need to cover _every_ version, but if we can have
specific knobs for individual features (like ASCIIDOC_NO_ROFF), then
maybe it makes sense to aggregate the settings for those knobs for a few
common versions.

Digging through the archive, it is hard to say. The original patch
mentions DOCBOOK_XSL_172 as if callouts.xsl were already doing this, but
I don't see any evidence that it ever did.

Definitely an improvement, IMHO. I wonder if we also want to consider
making the "make" output a little nicer to Documentation/Makefile,
similar to how the main Makefiles just prints "CC".

Thank you for looking at these. I will incorporate your feedback and  
resend in a couple of days.

I used -C -M in some early diffs to make sure it would "compress"  
like that, but I failed to do so for the final send-email.

Right. I went overboard with reworking the XSLT into "modules" for

I am not opposed to providing more version-specific controls, but I  
am not sure which versions are important enough to justify their own  
variables. Are you indicating that 1.73 is important enough because  
it was a "return to sanity" after 1.72?

The versions I listed in the comments were just the ones that the  
tools' documentation described as needing one adjustment or another.  
I thought the comments would be an easy way to start tracking which  
versions were "interesting".

[PATCH 2/2] Documentation/Makefile: break up texi pipeline

[Chris Johnsen]

Most shells define the exit value of a pipeline as the exit value
of the last process. For each texi rule, run the DOCBOOK2X_TEXI
tool and the "fixup" script in their own non-pipeline commands so
that make will notice an error exit code.

This textually depends on my "quiet doc gen" patch as it modifies
a couple of the same lines.

What's going on here? The line you remove is part of the dependencies,
but you replace it with a line of build instructions (and make barfs, of
course).

Yes, I botched that one. The QUIET_GEN should have been on the
next line. Thanks for catching it. I fixed it along with error
propagation and initially-also-botched "&& chaining" for
gitman.texi. I also added QUIET_XSLTPROC for user-manual.html.

I tested the man, html, info, and git-add.texi targets
(previously I only ran man and info targets; git-add.texi
exercises a rule not otherwise used in the usual targets).

An interdiff from "v1" to what I have now follows (it include
parts that would be in 1/2 and 2/2 from "v1").

Thanks.  I noticed that between you and Jeff there were some more
improvements discussed, but I tried this round (queued in 'pu') and the
results lost those infamous ".ft", which is very good ;-)

I also noticed you have a two-patch series to quiet the documentation
building procedure, but didn't queue after seeing you had "oops".

I am looking forward to seeing v2 of both series.  Thanks.

And thanks, Jeff, for helping to get these series into shape.

Great, thanks.

FWIW, I just set diff.renames in my git repo so I don't have to remember
(the only reason not to generate renames for format-patch is if the
recipient is not using git to apply -- but it is a pretty safe
assumption that people here are using git).

No, mainly because it is what is shipped in the last version of Debian,
which means it is a major enough version that there will be a lot of
people using it.

But let's just start with adding the tweakable knobs (which your series
is already doing), and see in what ways they need to be tweaked for
popular platforms before going overboard.

When I was trying out the series yesterday, I was wondering if this is
something we can autodetect.

Output from "asciidoc --version" is easily machine parsable for giving
asciidoc7compatible aka ASCIIDOC8, but I couldn't come up with anything
simpler than probing a few hardcoded paths under /usr/share/sgml; that
approach is unacceptable because would not work if your stylesheets are in
somewhere we do not know about.  Ideally, we should be able to ask the
tools we invoke (e.g. xmlto) to get that information.

Maybe run asciidoc/xmlto on a minimal test file and check the output?
"autoconf lite", so to say.
