It is now possible to return a single filter from a filter file, e.g.
``` lua
-- Switch single- and double quotes
return {
Quoted = function (q)
elem.quotetype = elem.quotetype == 'SingleQuote'
and 'DoubleQuote' or 'SingleQuote'
return elem
end
}
The filter must not contain numerical indexes, or it might be treated as
a list of filters.
Pandoc already depends on `crypton-conntection`, and thus transitively
on `crypton`. The latter provides a vast variety of hashing algorithms
and makes the dependency on SHA unnecessary.
Two new command-line options are added:
`--lof[=true|false]`, `--list-of-figures[=true|false]`
`--lot[=true|false]`, `--list-of-tables[=true|false]`
Only docx, latex, and context are supported at this point.
Setting the `lof` and `lot` variables will also work for the formats that are
currently supported.
[API changes]
+ Lua: `list_of_figures` and `list_of_tables` can now be used in writer options.
+ Text.Pandoc.Options: add `writerListOfFigures` and `writerListOfTables` fields
to `WriterOptions`.
+ Text.Pandoc.App.Opt: add `optListOfFigures` and `optListOfTables` to `Opt`.
Closes#8245.

The `Doc` values produced and handled by the `pandoc.layout` module can
now be styled using `bold`, `italic`, `underlined`, or `strikeout`. The
style is ignored in normal rendering, but becomes visible when rendering
to ANSI output. The `pandoc.layout.render` function now takes a third
parameter that defines the output style, either *plain* or *ansi*.
The module now comes with a method `:at(index[, def])` that allows to access
indices, accepts negative indices to count from the end, and will return the
`def` value as a default if the list has no item at the given position.
Furthermore, the list constructor `pandoc.List` now accepts iterators. E.g.,
`pandoc.List(text:gmatch '%S+')` returns the list of words in `text`.
Closes: #9835
- Document in defaults file section of MANUAL.
- Add to pandoc-lua-engine writer option marshalling.
- Add to pandoc-server initialization of writer options.
The modules `lpeg` and `re` are now treated as if they had been
loaded with `require`. Previously the modules were only assigned
to global values, but could be loaded again via `require`,
thereby allowing to use a system-wide installation. However, this
proved to be confusing.
The old behavior can be restored by adding the following lines to
the top of Lua scripts, or to the `init.lua` in the data dir.
debug.registry()['_LOADED'].lpeg = nil
debug.registry()['_LOADED'].re = nil
The function allows to specify a template with the same argument value
that would be used with the `--template` command line parameter.

The state is an internal value and should be treated as such. The
`PANDOC_STATE` global is merely a copy; unsetting the global no longer
breaks the Lua engine.
The default is now to use a *copy* of the global environment when running a
filter; this ensures better separation when `run_lua_filter` is used multiple
times. A custom environment can be specified via the optional third parameter.
Lists created by `pandoc.json.decode` now behave like lists generated
via `pandoc.List`. This also ensures that `pandoc.List` tables are
encoded as JSON arrays when passed to `pandoc.json.encode`.
Fixes: #9834
This fixes counterintuitive behavior of the `content` property on
BulletList and OrderedList items. Unmarshalling of that field now
matches the behavior of the constructor.
Fixes: #8916
Invalid input bytes in error messages caused pandoc to crash with an
encoding exception. Instead, the invalid bytes are now replaced with the
Unicode replacement character U+FFFD.
+ When the optional base level parameter is provided, we no
longer ensure that the sequence of heading levels is gapless
[behavior change]. Instead, we set the lowest heading level to
the specified base level, and adjust the others accordingly. If
an author wants to skip a level, e.g. from level 1 to level 3,
they can do that. In general, the heading levels specified
in the source document are preserved; `makeSections` only
puts them into a hierarchical structure. Closes#9398.
+ Section numbers are now assigned so that the top level
gets `1`, no matter what heading level is used. So, even
if the top heading level is 2, numbers will be `1`, `2`, etc.
rather than `0.1`, `0.2`, as in the past. Closes#5071.
+ We revert to the old behavior when the `--number-offset` option
is used. So, for example, if a document begins with a level-3
heading, and `--number-offset=1,2` is used, the top-level section
numbers will be `1.2.1`, `1.2.2`, etc. This is mainly for
backwards-compatibility.
The CommonState (`PANDOC_STATE` in Lua) may change between the time that
a custom writer script is first loaded and when the writer is run.
However, the writer was always using the initial state, which led to
problems, e.g. when the mediabag was updated in a filter, as those
updates where not visible to the writer.
The state is now updated right before the writer function runs.
