This will allow us to compare files directly in a golden test. Times
are still based on IO, but we will be able to safely skip those.
Changes:
- `getUniqueId` now calls to the state to get an incremented digit,
instead of calling to P.uniqueHash.
- we always start the PRNG in mkNumbering/mkAbstractNum with the same
seed (1848), so our randoms should be the same each time.
Comments from `--track-changes=all` were producing corrupt docx,
because the writer was trying to get id from the `(ID,_,_)` field of
the attributes, and ignoring the "id" entry in the key-value pairs. We
now check both.
There is a larger conversation to be had about the right way to treat
"id" and "class" entries in kvs, but this fix will correctly interpret
the output of the docx reader work.
Fixes#2609.
This PR introduces the new-style section headings: `\section[my-header]{My Header}` -> `\section[title={My Header},reference={my-header}]`.
On top of this, the ConTeXt writer now supports the `--section-divs` option to write sections in the fenced style, with `\startsection` and `\stopsection`.
This also necessitated implementing colors and underlining, though
there is currently no way to produce these from markdown. Note that
background colors can't be implemented in PowerPoint, so highlighting
styles that require these will be incomplete.
This picks up the necessary information from meta and carries it over
to the XML output, so Output.hs doesn't need access to the original
pandoc information.
This is an internal change to the Presentation type. The algebraic
datatype that used to be called `Slide` is now `Layout`, and Slide is
defined as `Slide SlideId Layout (Maybe Notes)`. Though there should
be no user-visible changes in this commit, it offers two benefits
moving forward:
1. Slides now carry their Id with them, instead of being assigned it
in deck order. This makes it easier to set up a link to, say, an
endnotes slide ahead of time.
2. This makes room for Notes slides, when we implement them.
Previously we could get ever-lengthening cell widths
when a table was run repeatedly through `pandoc -f markdown -t
markdown`. This patch stabilizes the relative cell
widths. Closes#4265.
The toplevel .rels file could have a thumbnail image if taken from the
template. Rather than removing it from the inherited file, it's easier
to just make our own.
There was a glob error that was leading to images from the
reference-doc pptx not being imported. We don't need a glob here --
just replace it with `isPrefixOf`.
We don't need it for anything but the log messages, and we can just
keep track of that in state and pass it along to the `writePowerpoint`
function. This will simplify the code.
We don't convert a '#target' ExternalTarget to an InternalTarget if
`target` is not in the AnchorMap. We just remove the link. This
prevents broken links in the Powerpoint output.
They were broken when I refactored (the Output module wanted to use
state left over from the construction of the Presentation type). This
change introduces a new type `LinkTarget = InternalTarget |
ExternalTarget`. Internal target points to a slide number, and these
will all be resolved before the Presentation is passed along to the
Output module.
There are two steps in the conversion: a conversion from pandoc to a
Presentation datatype modeling pptx, and a conversion from
Presentation to a pptx archive. The two steps were sharing the same
state and environment, and the code was getting a bit
spaghetti-ish. This separates the conversion into separate
modules (T.P.W.Powerpoint.Presentation, which defineds the
Presentation datatype and goes Pandoc->Presentation)
and (T.P.W.Pandoc.Output, which goes Presentation->Archive).
Text.Pandoc.Writers.Powerpoint a thin wrapper around the two modules.
Just as a slide can't have an image and text on the same slide because
of overlapping, we can't have both in a single column. We run
splitBlocks on the text in the column and discard the rest.
We put `getContentShape` and `getContentShapeSize` inside the P monad,
so that we can (in the future) make use of knowledge of what slide
environment we're in to get the correct shape. This will allow us, for
example, to get individual columns for a two-column layout, and place
images in them appropriately.
We now determine image and caption placement by getting the dimensions
of the content box in a given layout. This allows for images to be
correctly sized and positioned in a different template.
Note that iamges without captions and headers are no longer
full-screened. We can't do this dependably in different layouts,
because we don't know where the header is (it could be to the side of
the content, for example).
Our presentation size is now dependent on the reference/template file
we use. This will make it easier to set different output sizes by
supplying different reference files. The alternative (allowing a user
to explicitly set output size regardless of the template) will lead to
too many thorny issues, as explicitly set sizes at the various level
of powerpoint layout would have to be reset.
