We already copy the relationships and elements in presentation.xml for
embedded fonts, so at the moment using a reference doc with embedded
fonts is broken, producing a pptx that PowerPoint says needs repairing.
This commit copies the fonts over, which I believe is all that’s needed
to work correctly with reference docs with embedded fonts.
Before now, the numbering of rIds was inconsistent when making the
presentation XML and when making the presentation relationships XML.
For the relationships, the slides were inserted into the rId order after
the first master, and everything else was moved up out of the way.
However, this change was then missed in the presentation XML, I think
because `envSlideOffset` was never set. The result was that any slide
masters after the first would have the wrong rIds in the presentation
XML, clashing with the slides, which would lead PowerPoint to view
produced files as corrupt. As well, other relationships (like embedded
fonts) would have their rId changed in the relationships XML but not in
the presentation XML.
This commit:
- Removes `envSlideOffset` in favour of directly passed function
arguments
- Inserts the slides into the rId order after all masters rather than
after the first
- Updates any other rIds in presentation.xml that need to be changed
- Accept test changes: they’re adding the second theme (for all tests
not containing speaker notes), or changing its position in the
XML (for the ones containing speaker notes).
Before now, for any layouts added to the output from the default
reference doc, the relationships were unconditionally added to the
output. However, if there was already a layout in slideMaster1 at the
same index then that results in duplicate relationships.
This commit checks first, and only adds the relationship if it doesn’t
already exist.
The HTML writer now supports `EndOfBlock`, `EndOfSection`, and
`EndOfDocument` for reference locations. EPUB and HTML slide
show formats are also affected by this change.
This works similarly to the markdown writer, but with special care
taken to skipping section divs with what regards to the block level.
The change also takes care to not modify the output if `EndOfDocument`
is used.
We now ensure that groups starting with `\*` never cause
text to be added to the document.
In addition, bookmarks now create a span between the start
and end of the bookmark, rather than an empty span.
Until now, the pptx writer only supported four slide layouts: “Title
Slide” (used for the automatically generated metadata slide), “Section
Header” (used for headings above the slide level), “Two Column” (used
when there’s a columns div containing at least two column divs), and
“Title and Content” (used for all other slides).
This commit adds support for three more layouts: Comparison, Content
with Caption, and Blank.
- Support “Comparison” slide layout
This layout is used when a slide contains at least two columns, at
least one of which contains some text followed by some non-text (e.g.
an image or table). The text in each column is inserted into the
“body” placeholder for that column, and the non-text is inserted into
the ObjType placeholder. Any extra content after the non-text is
overlaid on top of the preceding content, rather than dropping it
completely (as currently happens for the two-column layout).
+ Accept straightforward test changes
Adding the new layout means the “-deleted-layouts” tests have an
additional layout added to the master and master rels.
+ Add new tests for the comparison layout
+ Add new tests to pandoc.cabal
- Support “Content with Caption” slide layout
This layout is used when a slide’s body contains some text, followed by
non-text (e.g. and image or a table). Before now, in this case the image
or table would break onto a new slide: to get that output again, users
can add a horizontal rule before the image or table.
+ Accept straightforward tests
The “-deleted-layouts” tests all have an extra layout and relationship
in the master for the Content with Caption layout.
+ Accept remove-empty-slides test
Empty slides are still removed, but the Content with Caption layout is
now used.
+ Change slide-level-0/h1-h2-with-text description
This test now triggers the content with caption layout, giving a
different (but still correct) result.
+ Add new tests for the new layout
+ Add new tests to the cabal file
- Support “Blank” slide layout
This layout is used when a slide contains only blank content (e.g.
non-breaking spaces). No content is inserted into any placeholders in
the layout.
Fixes#5097.
+ Accept straightforward test changes
Blank layout now copied over from reference doc as well, when
layouts have been deleted.
+ Add some new tests
A slide should use the blank layout if:
- It contains only speaker notes
- It contains only an empty heading with a body of nbsps
- It contains only a heading containing only nbsps
- Change ContentType -> Placeholder
This type was starting to have a constructor for each placeholder on
each slide (e.g. `ComparisonUpperLeftContent`). I’ve changed it
instead to identify a placeholder by type and index, as I think that’s
clearer and less redundant.
- Describe layout-choosing logic in manual
- Use dashes consistently rather than underscores
- Make a folder for each set of tests
- List test files explicitly (Cabal doesn’t support ** until version
2.4)
+ Add sandbox feature for readers. When this option is used,
readers and writers only have access to input files (and
other files specified directly on command line). This restriction
is enforced in the type system.
+ Filters, PDF production, custom writers are unaffected. This
feature only insulates the actual readers and writers, not
the pipeline around them in Text.Pandoc.App.
+ Note that when `--sandboxed` is specified, readers won't have
access to the resource path, nor will anything have access to
the user data directory.
+ Add module Text.Pandoc.Class.Sandbox, defining
`sandbox`. Exported via Text.Pandoc.Class. [API change]
Closes#5045.
This change has several parts:
- In Text.Pandoc.App, if the writer is docx, we fill the media
bag and attempt to convert any SVG images to PNG, adding these
to the media bag. The PNG backups have the same filenames as
the SVG images, but with an added .png extension. If the conversion
cannot be done (e.g. because rsvg-convert is not present),
a warning is omitted.
- In Text.Pandoc.Writers.Docx, we now use Word 2016's syntax for
including SVG images. If a PNG fallback is present in the media bag,
we include a link to that too.
It would be helpful if someone with an old Word version could test
to see that the documents we produce can be opened and viewed with
the PNG fallbacks. If not, then perhaps we can eliminate the
slightly complex code for producing these fallbacks.
Closes#4058.
Before this commit, the pptx writer adds a slide break before any table,
“columns” div, or paragraph starting with an image, unless the only
thing before it on the same slide is a heading at the slide level. In
that case, the item and heading are kept on the same slide, and the
heading is used as the slide title (inserted into the layout’s “title”
placeholder).
However, if the slide level is set to 0 (as was recently enabled) this
makes it impossible to have a slide with a title which contains any of
those items in its body.
This commit changes this behaviour: now if the slide level is 0, then
items will be kept with a heading of any level, if the heading’s the
only thing before the item on the same slide.
Previously we used liftIO fairly liberally. The code has
been restructured to avoid this.
A small behavior change is that pandoc will now fall back
to latin1 encoding for inputs that can't be read as UTF-8.
This is what it did previously for content fetched from
the web and not marked as to content type. It makes sense
to do the same for local files.
