Previously we tried to get the image size from the image even
if an explicit size was specified. Since we still can't get
image size for PDFs, this made it impossible to use PDF images
in docx.
Now we don't try to get the image size when a size is already
explicitly specified.
This contains a JSON version of all the metadata, in the
format selected for the writer.
So, for example, to get just the YAML metadata, you can
run pandoc with the following custom template:
$meta-json$
Closes#2019. The intent is to make it easier for static
site generators and other tools to get at the metadata.
Change 5527465c introduced a `DummyListItem` type in Docx/Parse.hs. In
retrospect, this seems like it mixes parsing and iterpretation
excessively. What's *really* going on is that we have a list item
without and associate level or numeric info. We can decide what to do
what that in Docx.hs (treat it like a list paragraph), but the parser
shouldn't make that decision.
This commit makes what is going on a bit more explicit. `LevelInfo` is
now a Maybe value in the `ListItem` type. If it's a Nothing, we treat
it as a ListParagraph. If it's a Just, it's a normal list item.
* Removed setting of `subject` in PDF metadata.
This used to be set to the subtitle, but really the subtitle
need not give the subject. Also, `subtitle` can contain formatting,
so we'd need, at least, a plain text version for this.
* Moved `header-includes` before setting of `\title`, `\author`,
etc. This allows these macros to be redefined.
* Use `\subtitle` command for `subtitle`, instead of tacking it
on to the title as before. We give a no-op fallback definition if it is
not defined. This change should produce much better results
in classes that support `\subtitle`. With the default article
class, which does not define `\subtitle`, subtitles will no
longer be printed unless the user defines `\subtitle` and
redefines `\maketitle`.
* Moved redefinitions of `\paragraph` and `\subparagraph` to
before header-includes.
