Previously, when multiple file arguments were provided, pandoc
simply concatenated them and passed the contents to the readers,
which took a Text argument.
As a result, the readers had no way of knowing which file
was the source of any particular bit of text. This meant that
we couldn't report accurate source positions on errors or
include accurate source positions as attributes in the AST.
More seriously, it meant that we couldn't resolve resource
paths relative to the files containing them
(see e.g. #5501, #6632, #6384, #3752).
Add Text.Pandoc.Sources (exported module), with a `Sources` type
and a `ToSources` class. A `Sources` wraps a list of `(SourcePos,
Text)` pairs. [API change] A parsec `Stream` instance is provided for
`Sources`. The module also exports versions of parsec's `satisfy` and
other Char parsers that track source positions accurately from a
`Sources` stream (or any instance of the new `UpdateSourcePos` class).
Text.Pandoc.Parsing now exports these modified Char parsers instead of
the ones parsec provides. Modified parsers to use a `Sources` as stream
[API change].
The readers that previously took a `Text` argument have been
modified to take any instance of `ToSources`. So, they may still
be used with a `Text`, but they can also be used with a `Sources`
object.
In Text.Pandoc.Error, modified the constructor PandocParsecError
to take a `Sources` rather than a `Text` as first argument,
so parse error locations can be accurately reported.
T.P.Error: showPos, do not print "-" as source name.
..and add new definitions isomorphic to xml-light's, but with
Text instead of String. This allows us to keep most of the code in
existing readers that use xml-light, but avoid lots of unnecessary
allocation.
We also add versions of the functions from xml-light's
Text.XML.Light.Output and Text.XML.Light.Proc that operate
on our modified XML types, and functions that convert
xml-light types to our types (since some of our dependencies,
like texmath, use xml-light).
Update golden tests for docx and pptx.
OOXML test: Use `showContent` instead of `ppContent` in `displayDiff`.
Docx: Do a manual traversal to unwrap sdt and smartTag.
This is faster, and needed to pass the tests.

Using `--color`, which is equivalent to `--color=always`, causes
problems when used in situations where colors are not supported, e.g.,
in combination with Emacs. Detection of color-supporting environments
seems reliable, so no adverse effects are expected from this change.
A new type `SimpleTable` is made available to Lua filters. It is
similar to the `Table` type in pandoc versions before 2.10;
conversion functions from and to the new Table type are provided.
Old filters using tables now require minimal changes and can use,
e.g.,
if PANDOC_VERSION > {2,10,1} then
pandoc.Table = pandoc.SimpleTable
end
and
function Table (tbl)
tbl = pandoc.utils.to_simple_table(tbl)
…
return pandoc.utils.from_simple_table(tbl)
end
to work with the current pandoc version.
* Fix hlint suggestions, update hlint.yaml
Most suggestions were redundant brackets. Some required
LambdaCase.
The .hlint.yaml file had a small typo, and didn't ignore camelCase
suggestions in certain modules.
In modern hlint, the spurious parse errors are gone now that it no
longer uses HSE, and it's also smart enough to avoid the bad "Use =="
suggestions itself.
