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
|
|
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.
|
|
The image title (i.e. ``) was previously
ignored when writing to pptx. This commit includes it in PowerPoint's
description of the image, along with the link (which was already
included).
Fixes 7352.
|
|
Linkification of URLs in the bibliography is now done in
the citeproc library, depending on the setting of an option.
We set that option depending on the value of the metadata
field `link-bibliography` (defaulting to true, for consistency
with earlier behavior, though the new behavior includes the
CSL draft recommendation of hyperlinking the title or the whole
entry if a DOI, PMID, PMCID, or URL field is present but not
explicitly rendered).
These changes implement the following recommendations from the
draft CSL v1.0.2 spec (Appendix VI):
> The CSL syntax does not have support for configuration of links.
> However, processors should include links on bibliographic references,
> using the following rules:
> If the bibliography entry for an item renders any of the following
> identifiers, the identifier should be anchored as a link, with the
> target of the link as follows:
> - url: output as is
> - doi: prepend with "`https://doi.org/`"
> - pmid: prepend with "`https://www.ncbi.nlm.nih.gov/pubmed/`"
> - pmcid: prepend with "`https://www.ncbi.nlm.nih.gov/pmc/articles/`"
> If the identifier is rendered as a URI, include rendered URI components
> (e.g. "`https://doi.org/`") in the link anchor. Do not include any other
> affix text in the link anchor (e.g. "Available from: ", "doi: ", "PMID: ").
> If the bibliography entry for an item does not render any of
> the above identifiers, then set the anchor of the link as the item
> title. If title is not rendered, then set the anchor of the link as the
> full bibliography entry for the item. Set the target of the link as one
> of the following, in order of priority:
>
> - doi: prepend with "`https://doi.org/`"
> - pmcid: prepend with "`https://www.ncbi.nlm.nih.gov/pmc/articles/`"
> - pmid: prepend with "`https://www.ncbi.nlm.nih.gov/pubmed/`"
> - url: output as is
>
> If the item data does not include any of the above identifiers, do not
> include a link.
>
> Citation processors should include an option flag for calling
> applications to disable bibliography linking behavior.
Thanks to Benjamin Bray for getting this all working.

@undergroundquizscene - I think TemplateWarning
is apt to be confusing, since this actually doesn't have
anything to do with what we call 'templates' in pandoc.
Hence the change to a powerpoint-specific name.
|
|
Until now, users had to make sure that their reference doc contains
layouts in a specific order: the first four layouts in the file had to
have a specific structure, or else pandoc would error (or sometimes
successfully produce a pptx file, which PowerPoint would then fail to
open).
This commit changes the layout selection to use the layout names rather
than order: users must make sure their reference doc contains four
layouts with specific names, and if a layout with the right name isn’t
found pandoc will output a warning and use the corresponding layout from
the default reference doc as a fallback.
I believe the use of names rather than order will be clearer to users,
and the clearer errors will help them troubleshoot when things go wrong.
- Add tests for moved layouts
- Add tests for deleted layouts
- Add newly included layouts to slideMaster1.xml to fix tests
|
|
[Minor API change]
This allows pandoc to get size information from tiff images.
Closes #7405.
|
|
...not just using `--variable` on the command line (as in
other writers). Closes #7187.

..and add new definitions isomorphic to xml-light's, but with
Text instead of String. This allows us to keep most of the code in
existing readers that use xml-light, but avoid lots of unnecessary
allocation.
We also add versions of the functions from xml-light's
Text.XML.Light.Output and Text.XML.Light.Proc that operate
on our modified XML types, and functions that convert
xml-light types to our types (since some of our dependencies,
like texmath, use xml-light).
Update golden tests for docx and pptx.
OOXML test: Use `showContent` instead of `ppContent` in `displayDiff`.
Docx: Do a manual traversal to unwrap sdt and smartTag.
This is faster, and needed to pass the tests.

Setting SOURCE_DATE_EPOCH will allow reproducible builds.
Partially addresses #7093. This does not suffice to fully enable
reproducible in EPUB, since a unique id is being generated for each
build.

This exports functions that uses xml-conduit's parser to
produce an xml-light Element or [Content]. This allows
existing pandoc code to use a better parser without
much modification.
The new parser is used in all places where xml-light's
parser was previously used. Benchmarks show a significant
performance improvement in parsing XML-based formats
(especially ODT and FB2).
Note that the xml-light types use String, so the
conversion from xml-conduit types involves a lot
of extra allocation. It would be desirable to
avoid that in the future by gradually switching
to using xml-conduit directly. This can be done
module by module.
The new parser also reports errors, which we report
when possible.
A new constructor PandocXMLError has been added to
PandocError in T.P.Error [API change].
Closes #7091, which was the main stimulus.
These changes revealed the need for some changes
in the tests. The docbook-reader.docbook test
lacked definitions for the entities it used; these
have been added. And the docx golden tests have been
updated, because the new parser does not preserve
the order of attributes.
Add entity defs to docbook-reader.docbook.
Update golden tests for docx.

The raw text is now included verbatim in the output. Previously is was parsed
into XML elements, which prevented the inclusion of partial XML snippets.
|
|
* Fix hlint suggestions, update hlint.yaml
Most suggestions were redundant brackets. Some required
LambdaCase.
The .hlint.yaml file had a small typo, and didn't ignore camelCase
suggestions in certain modules.

(Instead of old Span with underline class.
Spans with `underline` will no longer be rendered
as underlined text.)
|
|
OMML in speaker notes would lead to corrupt PowerPoint output. We now
output the OMML verbatim as LaTeX in the speaker notes.
Closes #6301.
|
|
Deprecate `underlineSpan` in Shared in favor of `Text.Pandoc.Builder.underline`.
|
|
- Writers.Native is now adapted to the new Table type.
- Inline captions should now be conditionally wrapped in a Plain, not
a Para block.
- The toLegacyTable function now lives in Writers.Shared.
|
|
|
|
This should speed-up recompilation after changes in `Text.Pandoc.Class`,
as the number of modules affected by a change will be smaller in
general. It also offers faster insights into the parts of `T.P.Class`
used within a module.

* Use implicit Prelude
The previous behavior was introduced as a fix for #4464. It seems that
this change alone did not fix the issue, and `stack ghci` and `cabal
repl` only work with GHC 8.4.1 or newer, as no custom Prelude is loaded
for these versions. Given this, it seems cleaner to revert to the
implicit Prelude.
* PandocMonad: remove outdated check for base version
Only base versions 4.9 and later are supported, the check for
`MIN_VERSION_base(4,8,0)` is therefore unnecessary.
* Always use custom prelude
Previously, the custom prelude was used only with older GHC versions, as
a workaround for problems with ghci. The ghci problems are resolved by
replacing package `base` with `base-noprelude`, allowing for consistent
use of the custom prelude across all GHC versions.

PR #5884.
+ Use pandoc-types 1.20 and texmath 0.12.
+ Text is now used instead of String, with a few exceptions.
+ In the MediaBag module, some of the types using Strings
were switched to use FilePath instead (not Text).
+ In the Parsing module, new parsers `manyChar`, `many1Char`,
`manyTillChar`, `many1TillChar`, `many1Till`, `manyUntil`,
`mantyUntilChar` have been added: these are like their
unsuffixed counterparts but pack some or all of their output.
+ `glob` in Text.Pandoc.Class still takes String since it seems
to be intended as an interface to Glob, which uses strings.
It seems to be used only once in the package, in the EPUB writer,
so that is not hard to change.

This will allow structured values.

Starting numbers for ordered lists were previously ignored. Now we
specify the number if it is something other than 1.

This commit alters the way in which the Powerpoint writer treats
inline code and code blocks.
- Inline code is now formatted at the same size as the surrounding
text.
- Code blocks are now given a margin and font size according to their
level.
- Furthermore this commit allows changing the font with which code is
formatted via the `monofont` option.
Tested in
- PowerPoint 365 for Windows - 1808 (Build 10730.20344 Click-to-Run)
- PowerPoint 365 for Mac - 16.26 (19060901)

I had been using record syntax in an ADT, is bad style, since it means
that each record produces a partial function. Fortunately we weren't
using the partial functions anywhere, so this changes it to positional
syntax.
|
|
When editing a template/reference-doc, the user might be in Master
view, but when producing a slide show, it is assumed that slide view
will be desired. This removes the "lastView" attr from the
viewProps.xml slide so that the presentation will always open up in
slide view.
Note this requires creating a new "ppt/viewProps.xml" instead of just
moving over the old one from the viewProps file. Since this produces a
slightly different order of xml files in the content manifest, the
golden files will have to be rebuilt.

We don't build it at the moment, so it was causing corruption.
|
|
We were previously carrying over too many elements from the layout,
which produced visual artifacts and some corruption. This empties the
sptree (except for properties) after building the shapes, and then
inserts them.
Together with 5e944bf5, fixes #5402
(Note that this addresses the issue and template in that particular
bug report. Other issues will arise no doubt arise with other
templates.)
|
|
Previously we had applied content shapes based on their index (which
was "1", "2" in MS Word 2013). It turns out that this was a
convention, and could not be relied on. Instead we use a default
type (ie, a ph tag with no "type"). This is more correct, and should
make the application of reference documents in PowerPoint much more
robust.
|
|
This is the first step toward making templating work better. It seems
that content shapes have a default ph type. In other words, shapes
with *NO PH TYPE* should be considered to have an "obj" ph type, and
used as content shapes.
see https://github.com/scanny/python-pptx/blob/master/docs/dev/analysis/placeholders/slide-placeholders/placeholders-in-new-slide.rst
|
|
If the slide deck has a metadata slide (with author, title, etc) and
has speaker notes before any body content, the speaker notes will be
applied to the metadata slide. If there is no metadata slide, pandoc
will behave as before.
|
|
Previously, if notes came after a section-title header (ie, a level-1
header in a slide-level=2 presentation), they would go on the next
slide. This keeps them on the slide with the header.
|
|
The haddock module header contains essentially the
same information, so the boilerplate is redundant and
just one more thing to get out of sync.
|
|
Use span with single class "underline" as in docx writer.
|
|
Quite a few modules were missing copyright notices.
This commit adds copyright notices everywhere via haddock module
headers. The old license boilerplate comment is redundant with this and has
been removed.
Update copyright years to 2019.
Closes #4592.

* docx writer: support custom properties. Solves the writer part of #3024.
Also supports additional core properties: `subject`, `lang`, `category`,
`description`.
* odt writer: improve standard properties, including the following core properties:
`generator` (Pandoc/VERSION), `description`, `subject`, `keywords`,
`initial-creator` (from authors), `creation-date` (actual creation date).
Also fix date.
* pptx writer: support custom properties. Also supports additional core
properties: `subject`, `category`, `description`.
* Includes golden tests.
* MANUAL: document metadata support for docx, odt, pptx writers

The parameter is Extensions. This allows these functions to
be sensitive to the settings of `Ext_gfm_auto_identifiers` and
`Ext_ascii_identifiers`.
This allows us to use `uniqueIdent` in the CommonMark reader,
replacing some custom code.
It also means that `gfm_auto_identifiers` can now be used
in all formats.
Semantically, `gfm_auto_identifiers` is now a modifier of
`auto_identifiers`; for identifiers to be set, `auto_identifiers`
must be turned on, and then the type of identifier produced
depends on `gfm_auto_identifiers` and `ascii_identifiers` are set.
Closes #5057.

This allows raw openxml blocks and inlines to be used in the pptx
writer.
A few caveats:
1. It's up to the user to write well-formed openxml. The chances for
corruption, especially with such a brittle format as pptx, is pretty
high.
2. Because of the tricky way that blocks map onto shapes, if you are
using a raw block, it should be the only block on a slide (otherwise
other text might end up overlapping it).
3. The pptx ooxml namespace abbreviations are different from the docx ooxml
namespaces. Again, it's up to the user to get it right. Unzipped
document and ooxml specification should be consulted.
Closes: #4976

Remove exported functions `metaValueToInlines`, `metaValueToString`.
Add new exported functions `lookupMetaBool`, `lookupMetaBlocks`,
`lookupMetaInlines`, `lookupMetaString`.
Use these whenever possible for uniformity in writers.

`metaValueToString` wasn't in any released version.)
