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.
We had previously defaulted to slideLevel 2. Now we use the correct
behavior of defaulting to the highest level header followed by
content. We change an expected test result to match this behavior.
Previous version replaced *each* element from the template with the
new elements -- leading to multiple overlapping frames. This only
replaces the first instance, and throws out the rest.
Previously (a) the code size wasn't set when we force size, and (b)
the properties was set from the default, instead of inheriting. Both
of those problems were fixed.
A lot of work in the powerpoint writer is replacing XML from within
slidelayouts from templates. This function does a good deal of that
work, and this makes it preserve element order, as well as making it a
bit easier to understand.
This uses the columns/column div format described in the pandoc
manual. At the moment, only two columns (half the screen each) are
allowed. Custom widths are not supported.
Word 2016 seems to use a default value of "1" for table headers, if there is no firstRow definition (although a default value of 0 is documented), so all tables get the first Row formatted as header.
Setting the parameter to 0 if the table has no header row fixes this for Word 2016
instead of relying on CSS. Closes#4162. HTML-based templates have had
the custom CSS for div.line-block removed. Those maintaining custom
templates will want to remove this too.
We still enclose line blocks in a div with class line-block.
We don't yet produce incremental lists in PowerPoint, but we should at
least treat lists inside BlockQuotes as lists, for compatibility with
other slide formats.
