Possibly because they were not nested properly. I would expect the following to be recognized by the DocBook Writer:

we had the same thought but nope, that didn't show up in the docbook output. the title just ended up being a paragraph with no further adornment. :(

I would like it if footnotes were used more often but I agree that it should not block this work.

we're open to adding support for footnotes if there's the wish to keep them. we'll definitely have to add them if we ever decide to render the nixpkgs manual with nixos-render-docs, but this single occurences that's mostly a quip didn't justify the effort just yet.

Shouldn't this go in generatedSources?

we could probably merge the two into just generatedSources at this point, but for this PR we wanted to not disturb too much. once we get a different document layout scheme working the whole thing will have to be rewritten from scratch anyway.

we like it too! after some discussion on matrix we tried to make the switch to python 3.11, but that would require giving up python3Minimal for the environment so we ultimately didn't do it. switching to !Minimal is a good jump in closure size (and if we include the tests of markdown-it it's a huge jump in build closure size) is it worth doing anyway? no idea. it would give us match statements and |

oh, indeed it is. and with our concerns about 3.9 needing support having been alleviated from those matrix discussion ... we'll change those to matches. tomorrow 😅 |

... or maybe not tomorrow. unfortunately mypy is not sophisticated enough to analyze match statements properly. in all instances we've tried it has failed to properly destructure match arguments and caused incorrect typecheck failures. guess we'll have to discount match again after all 🙁 |

it's not used. holdover from when manpages were written in docbook.
this should be placed before the appendices, not between them. might even have a good place in the development part, but that's a decision for another day.
userconfiguration.xml hasn't existed for a while, and this comment will interfere with processing we'll be doing shortly.
pandoc renders these to multiple docbook paragraphs in a single definition for the term, not multiple *actual* definitions for the same term. this is most likely not what is intended here, so let's use multiple paragraphs instead.
markdown-it parses deflists slitghtly differently than pandoc does. in these two cases pandoc would find a deflist item while markdown-it would not, instead it'd find a lone colon and the rest of the text.
the examples for mkPackageOption weren't terminated, leading to pretty odd nesting of docbook (and thus html) elements. close them properly. also turn the (likewise unclosed) fenced div containing just an anchor id and a class that will be silently dropped to an inline anchor while we're here. we'd have to convert it anyway later.
pandoc drops .title classes when rendering to docbook, so these are effectively just paragraphs anyway. without support for including them in a table of contents the complexity of parsing them in nixos-render-docs won't be warranted.
pandoc would drop these when converting to docbook, just like it dropped .title block classes.
nixos-render-docs supports inline anchors, but not ids for blocks. it seems wise to reserve blocks for special cases that don't have other syntax already, like admonitions.
there's one remaining instance of literal docbook tags in the manual. replace it with a literal (as has been done for package tags everywhere else).
this is a lot easier than adding footnote support for just the one instance. if a use case for footnotes appears in the future (e.g. if we wanted to render the nixpkgs manual with nixos-render-docs as well) this decision should be reevaluated.
since support for kbd elements was added with explicit intent in #175128 it seems like a good idea to support this in nixos-render-docs instead of just dropping it in favor of `*F12*` etc. since it's a very rare thing in the manual and purely presentational it makes sense to use bracketed spans instead of a new myst role. the html-elements.lua plugin is now somewhat misnamed, but it'll go away very soon so we don't want to bother renaming it.
this is pretty much what pandoc calls bracketed spans. since we only want to support ids and classes it doesn't seem fair to copy the name, so we'll call them "attributed span" for now. renderers are expected to know about *all* classes they could encounter and act appropriately, and since there are currently no classes with any defined behavior the most appropriate thing to do for now is to reject all classes.
this lets us parse the `[F12]{.keycap}` syntax we recently introduced to
the nixos manual markdown sources. the docbook renderer emits the keycap
element for this class, the manpage renderer will reject it because it's
not entirely clear what to do with it: while html has <kbd> mandoc has
nothing of the sort, and with no current occurences in options doc we
don't have to settle on a (potentially bad) way to render these.
this should've been a core rule from the beginning. not being a core rule made it always run after smartquotes and replacements, which could've wrecked the id.
this is used by release notes (and we don't want to break links to those), and is also technically allowed anyway. we will *not* extend the regex to allow more characters just yet due to a mozilla recommendation against it (cf https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/id)
rules are a better place for this. since _post_parse is now empty (and presumably will never grow) we'll remove that as well.
this is a subset of pandoc's fenced divs. currently we only use this for admonitions (which get a new name to differentiate them from other kinds of blocks), but more users will appear soon.
this is currently only supported by the docbook exporter, and even the docbook exporter doesn't do much with them. we mirror the conversion pandoc did for consistency with the previous manual chapter conversion, which is to add just an anchor with the given id. future exporters that go directly to html might want to do more.
we'll soon add another docbook converter that does not emit a section as a collection of chapters, but sections or chapters on their own. this should clarify naming a bit before there can be any confusion.
render all manual chapters to docbook from scratch every time the manual is built. nixos-render-docs is quick enough at this to not worry about the cost (needing only about a second), and it means we can remove md-to-db.sh in the next commit. no changes to the rendered html manual except for replacements and smartquotes.
with manual chapters no longer needing pandoc for their conversion to xml we can get rid of this source of confusion, and its huge cache of xml files.

another update for release notes conflicts. going to wait for CI and then merge since this has been approved twice and is liable to produce conflicts at a very regular pace. |
Description of changes
we already have a markdown renderer for module manual chapters to docbook. the remaining non-module manual chapters use a few more features that are not yet present in nixos-render-docs, so lets add those and make md-to-db.sh a thing of the past.
apart from actual bugfixes to the manual and smartquotes/replacements there are no rendering changes to the html manual. manpage is unaffected. unlike md-to-db.sh converting all chapters with nixos-render-docs is reasonably fast and doesn't need to be cached (nor can it be once we're done with the whole deal, so we didn't even try to add caching here).
this should not be considered the final form of manual rendering to docbook. for rendering to html we will need an external document structuring mechanism that we haven't fully worked out yet, but that mechanism should also be used for docbook once it's implemented to avoid duplication.
note: that the nixos manual check fails is expected since md-to-db.sh is gone. this pr includes removal of this workflow.
