2021-08-28Add more potential threats to security section of manual.John MacFarlane1-3/+11
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.
2021-08-28Remove 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.
2021-08-27Image: Generalize svgToPng to MonadIO.John MacFarlane1-4/+5
2021-08-27Add haddock for dpi parameter.John MacFarlane1-1/+1
2021-08-27T.P.Image: svgToPng, change first parameter from WriterOptions to Int.John MacFarlane1-4/+4
The information we need is just a DPI, so why require more?
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.
2021-08-27Ensure we have unique ids for wp:docPr and pic:cNvPr elements.John MacFarlane3-9/+11
This will, I hope, fix #7527 and #7503.

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.
2021-08-24Text.Pandoc.Class: add readStdinStrict method to PandocMonad.John MacFarlane5-0/+17
[API change]
2021-08-24Class: Generalize type of extractMedia.John MacFarlane1-1/+1
It was uselessly restricted to PandocIO, instead of any instance of PandocMonad and MonadIO. [API change]
2021-08-24T.P.App.OutputSettings: Generalize some types...John MacFarlane2-7/+6
so we can run this with any instance of PandocMonad and MonadIO, not just PandocIO.
2021-08-24Text.Pandoc.Filter: Generalize type of applyFilters...John MacFarlane3-9/+91
from PandocIO to any instance of MonadIO and PandocMonad. [API change]
2021-08-24PDF: generalize type of makePDF...John MacFarlane1-40/+55
instead of PandocIO, it can be used in any instance of PandocMonad, MonadIO, and MonadMask. [API change]
2021-08-24Lua subsystem and custom writers: generalize types from PandocIO...John MacFarlane3-8/+8
to any instance of PandocMonad and MonadIO. This involves an API change, since the type of runLua is now (PandocMonad m, MonadIO m) => Lua a -> m (Either PandocError a)
2021-08-24Fix test for #7521.John MacFarlane1-2/+2
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.
2021-08-22PandocIO: derive MonadCatch, MonadThrow, MonadMask.John MacFarlane1-0/+4
This will allow us to use withTempDir.

2021-08-20RST reader: Fix `:literal:` includes.John MacFarlane2-6/+3
These should create code blocks, not insert raw RST. Closes #7513.

2021-08-19Improve docx reader's robustness in extracting images.John MacFarlane1-5/+6
The docx reader made a couple assumptions about how docx containers were laid out that were not always true, with the result that some images in documents did not get found/extracted. Closes #7511.
2021-08-19Clarify that each YAML block is a separate YAML documentWilliam Lupton1-0/+4
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.
2021-08-17Document new link-bibliography metadata field.John MacFarlane1-3/+10
This affects whether hyperlinks are added to the bibliography by citeproc.
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.
2021-08-17Use released citeproc 0.5.John MacFarlane3-8/+2
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.
2021-08-17Provide more detailed XML diff in testsEmily Bourke1-21/+51
I had some failing tests and couldn’t tell what was different in the XML. Updating the comparison to return what’s different made it easier to figure out what was wrong, and I think will be helpful for others in future.
2021-08-17Add TemplateWarning log message type [API change]Emily Bourke1-0/+6
This is a general warning to use for messages about templates.
2021-08-17Escape backslashes in haddock comments (#7505)Emily Bourke1-4/+4
Any literal backslash needs to be escaped: these are currently showing up as “‘r’” instead of “‘\r’”. Co-authored-by: Emily Bourke <undergroundquizscene@protonmail.com>
2021-08-16Fix bug in last commit due to removal of take1WhileP.John MacFarlane1-2/+2
2021-08-15Multimarkdown sub- and superscripts (#5512) (#7188)OCzarnecki4-15/+80
Added an extension `short_subsuperscripts` which modifies the behavior of `subscript` and `superscript`, allowing subscripts or superscripts containing only alphanumerics to end with a space character (eg. `x^2 = 4` or `H~2 is combustible`). This improves support for multimarkdown. Closes #5512. Add `Ext_short_subsuperscripts` constructor to `Extension` [API change]. This is enabled by default for `markdown_mmd`.
