This change introduces a reader for mdoc, a roff-derived semantic markup
language for manual pages. The two relevant contemporary implementations
of mdoc for manual pages are mandoc (https://mandoc.bsd.lv/), which
implements the language from scratch in C, and groff
(https://www.gnu.org/software/groff/), which implements it as roff macros.
mdoc has a lot of semantics specific to technical manuals that aren't
representable in Pandoc's AST. I've taken a cue from the mandoc HTML
output and many mdoc elements are encoded as Codes or Spans with classes
named for the mdoc macro that produced them.
Much like web browsers with HTML, mandoc attempts to produce best-effort
output given all kinds of weird and crappy mdoc input. Part of the
reason it's able to do this is it uses a very accommodating parse tree
and stateful output routines specialized to the output mode, and when it
encounters some macro it wasn't expecting, it can easily give up on
whatever it was outputting and output something else. I've encoded as
much flexibility as I reasonably could into the mdoc reader here, but I
don't know how to be as flexible as mandoc.
This branch has been developed almost exclusively against mandoc's
documentation and implementation of mdoc as a reference, and the
real-world manual pages tested against are those from the OpenBSD base
system. Of ~3500 manuals in mdoc format shipped with a fresh OpenBSD
install, 17 cause the mdoc reader to exit with a parse error. Any
further chasing of edge cases is deferred to future work.
Many of the tests in test/Tests/Readers/Mdoc.hs are derived directly
from mandoc's extensive regression tests.
[API change] Adds readMdoc to the public API

The existing lexRoff does some stuff I don't want to deal with in mdoc
just yet, like lexing tbl, and some stuff I won't do at all, like
handling macro and text string definitions and switching between modes.
Uses a typeclass with associated type families to reuse most of the
escaping code between Roff (i.e. man) and Mdoc.
Future work could improve on this so that more lexing code could be
shared between Man and Mdoc. Mdoc inherits Roff's surface syntax so
hypothetically it makes sense to lex it into tokens that make sense for
roff. But it happens that the Mdoc parser is much easier to build with
an Mdoc specific token stream. Some discussion in jgm/pandoc#10225 about
the rationale.
Adds a test for the roff \A escape, which I accidentally dropped support
for in an earlier iteration without anything complaining.

The plain writer behaved as a markdown variant with Ext_line_blocks
turned off, and so empty lines in a line block would get eliminated.
This is surprising, since if there's anything where the intent can be
preserved in plain text output it's empty lines.
It's still a bit surprising to have nbsps in plain text output, as in
the test, where the distinction doesn't really matter, but that'd be an
orthogonal change.

Remove unnecessary definition of `endnote`.
Incorporate the one remaining definition into `default.typst`.
|
|
This can be set to an empty string (or, in metadata, to false) for
no page numbers.
Addresses #10370.

Note: the new templates presuppose typst 0.12; if you try to
use an earlier version of typst, an error will be raised.

Divs are unwrapped if the only purpose of the div seems to be to control

Create MetaInlines when possible, just as with markdown input.
MetaBlocks is still used when there are multiple paragraphs or
non-paragraph content.
This change also affects field lists.

For example, ``Go to `g`_ `g <www.example.com>`_.``
should produce two links to www.example.com.
Closes #5081.

Instead of having an initial pass where we collect reference
definitions, we create links with target `##SUBST##something`
or `##REF##something` or `##NOTE##something`, and resolve these
in a pass over the parsed AST.
This allows us to handle link references that are not at the
top level. Closes #10281.

If `smart` is not enabled, a command in the default template will
disable smartquote substitutions.
When `smart` is enabled, render curly apostrophes as straight
and escape straight apostrophes.
When `smart` is disabled, render curly apostrophes as curly
and don't escape straight apostrophes.
And similarly for quotes, em and en dashes.
This should give more idiomatic typst output, with fewer unnecessary
escapes.

+ Remove section numbering code from common.latex
+ Add section numbering to default.latex
+ Add logic for numbering sections in default.beamer. I moved the template setting
code to where other beamer templates are set. This makes the section-titles and
numbersections variables independent.
This should make --number-sections work with beamer.
|
|
This accords with the style in the reference docs.
|
|
With this patch, we also reuse bullet list code for list tables,
which simplifies the code.
|
|
In these cases we emit an empty comment to fix the point from
which indentation is measured; otherwise the block quote is not
parsed as a block quote.
This affects list items and admonitions.
Cloess #10236.

In commit a26ec96d89ccf532f7bca7591c96ba30d8544e4a we added an
empty `\item[]` to the beginning of a list that occurs first
in a definition list, to avoid having one item on the line with
the label.
This gave bad results in some cases (#10241) and there is a more
idiomatic solution anyway: using `\hfill`.
Closes #10241.

+ Split out common parts of latex template into partials: common.latex,
fonts.latex, font-settings.latex, passoptions.latex, hypersetup.latex,
after-header-includes.latex.
+ Split out old latex template into default.latex and default.beamer.
+ Make default.beamer the default template for beamer.

- Fix alignment of list items corresponding to cells.
- Don't enclose the list table in a `.. table::`; this leads to
doubled captions.

Allow for quoted code blocks.

Closes #6461.
Blockquotes are not really block containers in DokuWiki;
the lines are interpreted literally (so, e.g., you can't
start a list), and line breaks are added at the ends.
|
|
The use of these tags is now strongly discouraged for security
reasons, and will be removed.
We previously used them as a fallback for lists that could not
be represented using DokuWiki syntax, e.g. ordered lists with
fancy numbers or lists with multiple blocks in their items.
We also used them for block quotes with multiple blocks as
their contents.
We now use the `<WRAP>` syntax (from the optional WRAP plugin)
to handle lists with multiple blocks as their contents.
A new method of handling block quotes with complex contents
has the side benefit of also handling nested block quotes,
which weren't supported before.
`<HTML>` and `<html>` tags are only for raw HTML blocks and
inlines, and only if the `raw_html` extension is enabled. (It is
now a valid extension for `dokuwiki`, though off by default.)
Closes #7413.

Add parsing of id (xml:id), class, and tabstyle XML attributes
for table and informaltable in the DocBook reader.
The tabstyle value is put in the 'custom-style' attribute.

The new commonmark-pandoc version automatically adds the
attribute `wrapper="1"` on all Divs and Spans that
are introduced just as containers for attributes that belong
properly to their contents. So we don't need to add the
attribute here.
This gives much better results in some cases. Previously the
wrapper attribute was being added even for explicit Divs and
Spans in djot, but it is not needed in these cases.

The ANSI Superscript writer was copy-pasted and incompletely modified to
create the Subscript output writer and I forgot to call the right
function, so subscripts were getting rendered with superscripted
numbers. Adds a line for this to the ANSI golden test.

Previously they were always parsed as divs. But actually they
can occur in some "inline" contexts. Now we first try to parse
them as inlines, and only as blocks if that fails. A surrounding
Div or Span element is added only if there is an identifier.
