2021-09-23BibTeX parser: fix expansion of special strings in series...John MacFarlane1-7/+10
e.g. `newseries` or `library`. Expansion should not happen when these strings are protected in braces, or when they're capitalized. Closes #7591.
2021-09-23HTML reader: handle empty tbody element in table.John MacFarlane1-5/+8
Closes #7589.
2021-09-23HTML writer: render `\ref` and `\eqref` as inline math...John MacFarlane1-8/+11
not display. See #7589.
2021-09-22HTML writer: pass through `\ref` and `\eqref`...John MacFarlane1-2/+10
if MathJax is used. Closes #7587.
2021-09-22HTML writer: pass through inline math environments with KaTeX.John MacFarlane1-0/+1
2021-09-21Use pretty-simple to format native output.John MacFarlane1-73/+15
Previously we used our own homespun formatting. But this produces over-long lines that aren't ideal for diffs in tests. Easier to use something off-the-shelf and standard. Closes #7580. Performance is slower by about a factor of 10, but this isn't really a problem because native isn't suitable as a serialization format. (For serialization you should use json, because the reader is so much faster than native.)
2021-09-19LaTeX reader: Recognize that `\vadjust` sometimes takes "pre".John MacFarlane1-0/+7
Closes #7531.
2021-09-19Ignore (and gobble parameters of) CSLReferences environment.John MacFarlane1-0/+1
Otherwise we get the parameters as numbers in the output. Closes #7531.
2021-09-19Use babel, not polyglossia, with xelatex.John MacFarlane3-102/+13
Previously polyglossia worked better with xelatex, but that is no longer the case, so we simplify the code so that babel is used with all latex engines. This involves a change to the default LaTeX template.
2021-09-19Markdown writer: use `underline` class rather than `ul` for underline.John MacFarlane1-1/+1
This only affects output with bracketed_spans enabled. The markdown reader parses spans with either `.ul` or `.underline` as Underline elements, but we're moving towards preferring the latter.

2021-09-18pptx-footers: Replace fixed dates with yaml dateEmily Bourke2-8/+44
2021-09-18pptx: Support footers in the reference docEmily Bourke1-15/+88
In PowerPoint, it’s possible to specify footers across all slides, containing a date (optionally automatically updated to today’s date), the slide number (optionally starting from a higher number than 1), and static text. There’s also an option to hide the footer on the title slide. Before this commit, none of that footer content was pulled through from the reference doc: this commit supports all the functionality listed above. There is one behaviour which may not be immediately obvious: if the reference doc specifies a fixed date (i.e. not automatically updating), and there’s a date specified in the metadata for the document, the footer date is replaced by the metadata date. - Include date, slide number, and static footer content from reference doc - Respect “slide number starts from” option - Respect “Don’t show on title slide” option - Add tests
2021-09-17Fix linter warning.John MacFarlane1-4/+3
2021-09-17Org writer: don't indent contents of code blocks.John MacFarlane1-1/+1
We previously indented them by two spaces, following a common convention. Since the convention is fading, and the indentation is inconvenient for copy/paste, we are discontinuing this practice. Closes #5440.
2021-09-17Update list of supported source languages in org writer.John MacFarlane1-12/+44
See #5440.
2021-09-16Fix code blocks using `--preserve-tabs`.John MacFarlane1-1/+7
Previously they did not behave as the equivalent input with spaces would. Closes #7573.
2021-09-16pptx: Support specifying slide background imagesEmily Bourke2-36/+110
In the reveal-js output, it’s possible to use reveal’s `data-background-image` class on a slide’s title to specify a background image for the slide. With this commit, it’s possible to use `background-image` in the same way for pptx output. Only the “stretch” mode is supported, and the background image is centred around the slide in the image’s larger axis, matching the observed default behaviour of PowerPoint. - Support `background-image` per slide. - Add tests. - Update manual.
2021-09-16HTML writer: set "hash" to True by default (for reveal.js).John MacFarlane1-1/+1
Closes #7574. See #6968 where the motivation for setting "hash" to True is explained.
2021-09-15pptx: Add support for incremental listsEmily Bourke2-162/+455
- Support -i option - Support incremental/noincremental divs - Support older block quote syntax - Add tests One thing not clear from the manual is what should happen when the input uses a combination of these things. For example, what should the following produce? ```md ::: {.incremental .nonincremental} - are - these - incremental? ::: ::: incremental ::::: nonincremental - or - these? ::::: ::: ::: nonincremental > - how > - about > - these? ::: ``` In this commit I’ve taken the following approach, matching the observed behaviour for beamer and reveal.js output: - if a div with both classes, incremental wins - the innermost incremental/nonincremental div is the one which takes effect - a block quote containing a list as its first element inverts whether the list is incremental, whether or not the quote is inside an incremental/non-incremental div I’ve added some tests to verify this behaviour. This commit closes issue #5689 (https://github.com/jgm/pandoc/issues/5689).
2021-09-13RST reader: handle escaped colons in reference definitions.John MacFarlane1-1/+2
Cloess #7568.
2021-09-13pptx: Fix logic for choosing Comparison layoutEmily Bourke1-4/+5
There was a mistake in the logic used to choose between the Comparison and Two Content layouts: if one column contained only non-text (an image or a table) and the other contained only text, the Comparison layout was chosen instead of the desired Two Content layout. This commit fixes that logic: > If either column contains text followed by non-text, use Comparison. Otherwise, use Two Content. It also adds a test asserting this behaviour.
2021-09-12Docx writer: make id used in native_numbering predictable.John MacFarlane1-3/+6
If the image has the id IMAGEID, then we use the id ref_IMAGEID for the figure number. Closes #7551. This allows one to create a filter that adds a figure number with figure name, e.g. <w:fldSimple w:instr=" REF ref_superfig "><w:r><w:t>Figure X</w:t></w:r></w:fldSimple> For this to be possible it must be possible to predict the figure number id from the image id. If images lack an id, an id of the form `ref_fig1` is used.
2021-09-10fix!(ipynb writer): improve round trip identityKolen Cheung1-2/+2
for raw cell output BREAKING CHANGE: The Jupyter ecosystem, including nbconvert, lab and notebook, deviated from their own spec in nbformat, where they used the key `raw_mimetype` instead of `format`. Moreover, the mime-type of rst used in Jupyter deviated from that suggested by https://docutils.sourceforge.io/FAQ.html and is defined as `text/restructuredtext` when chosen from "Raw NBConvert Format" in Jupyter. So while this is backward-compatible, it should matches the real world usage better, hence improving the round-trip "identity" in raw-cell. See #229, jupyter/nbformat#229.
2021-09-10feat(ipynb writer): add more Jupyter's "Raw NBConvert Format"Kolen Cheung1-0/+7
Adds more formats that Jupyter's "Raw NBConvert Format" uses natively (asciidoc), and maps more formats to text/html whenever it makes sense.
2021-09-10feat(ipynb reader): get cell output mime from raw_mimetype tooKolen Cheung1-1/+2
While the spec defined format, in practice raw_mimetype is used. See jupyter/nbformat#229
2021-09-10feat(ipynb reader): add more Jupyter's "Raw NBConvert Format"Kolen Cheung1-6/+10
This adds most of the available formats selectable from Jupyter's interface "Raw NBConvert Format".
2021-09-10fix!: rst mime typeKolen Cheung1-1/+1
BREAKING CHANGE: fix rst mime type according to https://docutils.sourceforge.io/FAQ.html
2021-09-10pptx: Copy embedded fonts from reference docEmily Bourke1-0/+1
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.
2021-09-10pptx: Fix presentation rel numberingEmily Bourke1-63/+131
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
2021-09-10pptx: Include all themes in output archiveEmily Bourke1-4/+2
- 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).
2021-09-10pptx: Don’t add relationships unnecessarilyEmily Bourke1-5/+14
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.
2021-09-10pptx: Fix capitalisation of notesMasterIdEmily Bourke1-1/+1
I don’t think this has caused any problems, but before now it’s been "NotesMasterId", which is incorrect according to [ECMA-376]. [ECMA-376]: https://www.ecma-international.org/publications-and-standards/standards/ecma-376/
2021-09-10Remove redundant import.John MacFarlane1-1/+1
2021-09-10Org reader: don't parse a list as first item in a list item.John MacFarlane1-1/+4
Closes #7557.
2021-09-10Support `--reference-location` for HTML output (#7461)Francesco Mazzoli1-32/+89
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.
2021-09-10Ipynb reader handleData: support text/markdown (#7561)Kolen Cheung1-0/+3
`text/markdown` is now a supported mime type for raw output.
2021-09-08RTF reader: support `\binN` for binary image data.John MacFarlane1-11/+22
2021-09-08App: Issue NotUTF8Encoded warning when falling back to latin1.John MacFarlane1-2/+6

[API change]
2021-09-04RTF reader: better handling of `\*` and bookmarks.John MacFarlane1-8/+8
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.
2021-09-04Minor renaming to avoid shadowing.John MacFarlane1-2/+2
2021-09-04Extensions: put Ext_short_subsuperscripts in alphabetical order.John MacFarlane1-1/+1
2021-09-03RTF reader: if doc begins with {\rtf1 ... } only parse its contents.John MacFarlane1-1/+7
Some documents seem to have non-RTF (e.g. XML) material after the `{\rtf1 ... }` group.
2021-09-03RTF reader: Ignore `\pgdsc` group.John MacFarlane1-0/+1
Otherwise we get style names treated as test.
2021-09-01pptx: Add support for more layoutsEmily Bourke2-55/+313
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
2021-08-29Improve asciidoc escaping for `--` in URLs. Closes #7529.John MacFarlane1-3/+11
2021-08-28Add `--sandbox` option.John MacFarlane7-84/+107
+ 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.
2021-08-28Remove unneeded import.John MacFarlane1-1/+1
2021-08-28Docx writer: handle SVG images.John MacFarlane2-6/+56
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.
