We introduce a new module, Text.Pandoc.Readers.Docx.Fields which
contains a simple parsec parser. At the moment, only simple hyperlink
fields are accepted, but that can be extended in the future.
Rather than take user input, and place a "0." in front, actually
calculate the percentage to catch cases where small column sizes
(e.g. `2%`) are needed.
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.
rst2latex.py uses an align* environment for math in
`.. math::` blocks, so this math may contain line breaks.
If it does, we put the math in an `aligned` environment
to simulate rst2latex.py's behavior.
Closes#4254.
The change both improves performance and fixes a
regression whereby normal citations inside inline notes
were not parsed correctly.
Closesjgm/pandoc-citeproc#315.
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.
even if the `latex_macros` extension is set.
This reverts to earlier behavior and is probably safer
on the whole, since some macros only modify things in
included packages, which pandoc's macro expansion can't
modify.
Closes#4246.
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.
Above the slidelevel, subheaders will be printed in bold and given a
bit of extra space before them. Note that at the moment, no
distinction is made between levels of headers above the slide header,
though that can be changed. (It has to be changed in pandoc, since
PowerPoint has no concept of paragraph or character classes.)
This allows us to clean up the code as well: the code in
`blockToParagraphs` since it will only touch content blocks, and
therefore will not deal with headers at or below the slidelevel.
Since we now import from reference/dist file by glob, we need to make
sure that we're getting the files we need to make a non-corrupt
Powerpoint. This performs that check.
(In the process, this change also cleaned up a lot of commented-out
code left from the switch to the new reference-doc method.)
Templating should work much more reliably now. There is still some
problem with image placement when we change sizes. A further commit
will address this.
This is triggered by the `--toc` flag. Note that in a long slide deck
this risks overrunning the text box. The user can address this by
setting `--toc-depth=1`.
If the user entered an internal link without a corresponding anchor,
it would produce a corrupted file. Now we check the anchor map, and
make sure the target is in the file. If it isn't, we ignore it.
For anchor-type links (`[foo](#bar)`) we produce an anchor link. In
powerpoint these are links to slides, so we keep track of a map
relating anchors to the slides they occur on.
If you use a custom syntax definition that refers to a syntax
you haven't loaded, pandoc will now complain when it is highlighting
the text, rather than at the start.
This saves a huge performance hit from the `missingIncludes` check.
Closes#4226.
