e4f9d4f62c nixos/manual: fix cross-compilation
Remove absolute reference to xsltproc. This reference breaks cross-compilation: instead of host version builder tries to execute binary for target and fails.

3dc0323bae nixos/manual: apply options preprocessing to full manual
the conversion to the markdown-based workflow missed that generating the
manual as docbook also generates the option docs with nixos-specific
wrapper elements that require postprocessing before the document is
real, valid docbook. restore this processing to the full manual.

it's not the prettiest thing, done like this, but we only need it for
one release so it doesn't have to be.

54f4992e80 nixos/manual: render html with nixos-render-doc if !allowDocBook
this reproduces the docbook-generated html manual exactly enough to
appease the compare workflows while we still support both toolchains.
it's also a lot faster than the docbook toolchain, rendering the entire
html manual in about two seconds on this machine (while docbook needs
about 20).

81cf173256 nixos-render-docs: use multiprocessing for options
options processing is pretty slow right now, mostly because the
markdown-it-py parser is pure python (and with performance
pessimizations at that). options parsing *is* embarassingly parallel
though, so we can just fork out all the work to worker processes and
collect the results.

multiprocessing probably has a greater benefit on linux than on darwin
since the worker spawning method darwin uses is less efficient than
fork() on linux. this hasn't been tested on darwin, only on linux, but
if anything darwin will be faster with its preferred method.

1229e735ac nixos-render-docs: add structural includes, use for manual
this adds support for structural includes to nixos-render-docs.
structural includes provide a way to denote the (sub)structure of the
nixos manual in the markdown source files, very similar to how we used
literal docbook blocks before, and are processed by nixos-render-docs
without involvement of xml tooling. this will ultimately allow us to
emit the nixos manual in other formats as well, e.g. html, without going
through docbook at all.

alternatives to this source layout were also considered:

a parallel structure using e.g. toml files that describe the document
tree and links to each part is possible, but much more complicated to
implement than the solution chosen here and makes it harder to follow
which files have what substructure. it also makes it much harder to
include a substructure in the middle of a file.

much the same goes for command-line arguments to the converter, only
that command-lined arguments are even harder to specify correctly and
cannot be reasonably pulled together from many places without involving
another layer of tooling. cli arguments would also mean that the manual
structure would be fixed in default.nix, which is also not ideal.

ef413e3eac nixos/manual: split manpages-combined from manual-combined
once we generate the entire manual-combined.xml with a single
nixos-render-docs invocation we will no longer need any options xml
files. likewise we do not need the test options xml in the manpage
build. splitting manpages-combined from manual-combined also allows
these two to run in parallel, slightly improving build times.

652a283e51 nixos-render-docs: render manual chapters during manual build

is built. nixos-render-docs is quick enough at this to not worry about

10a4f0daca nixos-render-docs: add options manpage converter
mdoc is just too slow to render on groff, and semantic markup doesn't
help us any for generated pages.

this produces a lot of changes to configuration.nix.5, but only few
rendering changes. most of those seem to be place losing a space where
docbook emitted roff code that did not faithfully represent the input
text, though a few places also gained space where docbook dropped them.
notably we also don't need the compatibility code docbook-xsl emitted
because that problem was fixed over a decade ago.

this will handle block quotes, which the docbook stylesheets turned into
a mess of roff requests that ended up showing up in the output instead
of being processed.

0c601b12bf nixos/manual: translate manpages to mdoc
since we want to move away from docbook and having docbook manpages
around is going to block further progress we have to translate the
current nixos manpages from docbook it *something* else. mdoc seems the
most appropriate choice since markdown can't represent all the things
manpages can differentiate with even more extensions. if we ever need
html manpages we can render them using troff, like many of the online
manpage viewers, or rewrite them again. since we haven't had html
manpages for any of these in many years that seems unlikely to happen.

unlike most of the recent markdown conversions this comes with a lot of
minor rendering changes, mostly in spacing. docbook-xslt creates manual
pages in a very different dialect than mdoc (which is used here).

0a6e6cf7e6 nixos/manual: render module chapters with nixos-render-docs
this converts meta.doc into an md pointer, not an xml pointer. since we
no longer need xml for manual chapters we can also remove support for
manual chapters from md-to-db.sh

since pandoc converts smart quotes to docbook quote elements and our
nixos-render-docs does not we lose this distinction in the rendered
output. that's probably not that bad, our stylesheet didn't make use of
this anyway (and pre-23.05 versions of the chapters didn't use quote
elements either).

also updates the nixpkgs manual to clarify that option docs support all
extensions (although it doesn't support headings at all, so heading
anchors don't work by extension).

617822c95b nixos/manual: remove olinkdb
as far as we can tell nixos has only ever had a total of one olink, and
currently has no olinks at all. we can't currently represent olinks in
markdown docs, and if we re-add support for cross-document links they
will take a different form (and not use docbook, which will have to be
phased out before we re-add anything).

the olinkdb is thus unused and takes 10 seconds on our machine to build,
holding up the rest of the manual for no benefit.

49237015d6 nixos/doc: Make nixos-manual-combined fail easy to inspect
By writing the unchecked outputs before checking them, they will
be written to a store path, which appears in the log, and which
sticks around even if the build fails. Eventually it is GCed, but
until then, you can open the file.

If you run it in a terminal+editor combination like VSCode, the
failure location is just one Ctrl+click away.

84d6565d52 nixos/man: prevent duplication of options
libxslt 1.1.35 fixed conflict resolution for templates to match the specification.
This uncovered a bug in docbook-xsl (https://github.com/docbook/xslt10-stylesheets/issues/240),
which causes option names to be duplicated into the option descriptions.

Let’s resolve the conflict by patching the stylesheets.

fc614c37c6 nixos/documentation: split options doc build
most modules can be evaluated for their documentation in a very
restricted environment that doesn't include all of nixpkgs. this
evaluation can then be cached and reused for subsequent builds, merging
only documentation that has changed into the cached set. since nixos
ships with a large number of modules of which only a few are used in any
given config this can save evaluation a huge percentage of nixos
options available in any given config.

in tests of this caching, despite having to copy most of nixos/, saves
about 80% of the time needed to build the system manual, or about two
second on the machine used for testing. build time for a full system
config shrank from 9.4s to 7.4s, while turning documentation off
entirely shortened the build to 7.1s.

nixos: Split paras by \n\n in option descriptions
What annoyed me for a long time was the fact, that in order to break
into a new paragraph, you need to insert </para><para> in the
description attribute of an option.

Now we will automatically create <para/> elements for every block that
is separated by two consecutive newlines.

I first tried to do this within options-to-docbook.xsl, but it turns
out[1] that this isn't directly possible with XSLT 1.0, so I added
another XSLT file that postprocesses the option descriptions that are
now enclosed in <nixos:option-description/> by options-to-docbook.xsl.

The splitting itself is a bit more involved, because we can't simply
split on every \n\n because we'd also split text nodes of elements, for
example:

  <screen><![CDATA[

    one line

    another one

  ]]></screen>

This would create one <para/> element for "one line" and another for
"another line", which we obviously don't want because <screen/> is used
to display verbatim contents of what a user is seeing on the screen.

So what we do instead is splitting *only* the top-level text nodes
within the outermost <para/> and leave all elements as-is. If there are
more than one <para/> elements at the top-level, we simply don't process
it at all, because the description then already contains </para><para>.
