2021-09-01pptx: Add support for more layoutsEmily Bourke91-68/+580
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
2021-09-01pptx: Restructure testsEmily Bourke126-58/+111
- 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)

2021-08-28Add `--sandbox` option.John MacFarlane9-85/+120
+ 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.

2021-08-28Docx 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.

2021-08-27pptx: Make first heading title if slide level is 0Emily Bourke22-24/+85
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.

2021-08-24Reorganize App to make it easier to limit IO in main loop.John MacFarlane1-85/+100
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.

2021-08-24Lua subsystem and custom writers: generalize types from PandocIO...John MacFarlane3-8/+8

2021-08-23Markdown reader: fix interaction of --strip-comments and listJohn MacFarlane2-1/+12
parsing. Use of `--strip-comments` was causing tight lists to be rendered as loose (as if the comment were a blank line). Closes #7521.
2021-08-22Clean up PDF module.John MacFarlane1-59/+49
Previously we had to run runIOorExplode inside withTempDir. Now that PandocIO is an instance of MonadMask, this is no longer necessary.

2021-08-18pptx: Include image title in descriptionEmily Bourke10-12/+19
The image title (i.e. `![alt text](link "title")`) 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.
2021-08-17Revise citeproc code to fit new citeproc 0.5 API.John MacFarlane7-51/+21
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.

2021-08-17OOXML tests: silence warnings.John MacFarlane1-0/+1
These can make the test output confusing, making people think tests are failing when they're passing.
2021-08-17Rename TemplateWarning -> PowerpointTemplateWarning.John MacFarlane2-6/+7
@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.

2021-08-17pptx: Select layouts from reference doc by nameEmily Bourke47-33/+242
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
2021-08-17Don’t compare cdLine in OOXML golden testsEmily Bourke1-1/+0
The `cdLine` field gives the line of the file some CData was found on. I don’t think this is a difference that should fail these golden tests, as the XML should still be parsable if nothing else has changed.
