2020-09-21Add built-in citation support using new citeproc library.John MacFarlane1-21/+58
This deprecates the use of the external pandoc-citeproc filter; citation processing is now built in to pandoc. * Add dependency on citeproc library. * Add Text.Pandoc.Citeproc module (and some associated unexported modules under Text.Pandoc.Citeproc). Exports `processCitations`. [API change] * Add data files needed for Text.Pandoc.Citeproc: default.csl in the data directory, and a citeproc directory that is just used at compile-time. Note that we've added file-embed as a mandatory rather than a conditional depedency, because of the biblatex localization files. We might eventually want to use readDataFile for this, but it would take some code reorganization. * Text.Pandoc.Loging: Add `CiteprocWarning` to `LogMessage` and use it in `processCitations`. [API change] * Add tests from the pandoc-citeproc package as command tests (including some tests pandoc-citeproc did not pass). * Remove instructions for building pandoc-citeproc from CI and release binary build instructions. We will no longer distribute pandoc-citeproc. * Markdown reader: tweak abbreviation support. Don't insert a nonbreaking space after a potential abbreviation if it comes right before a note or citation. This messes up several things, including citeproc's moving of note citations. * Add `csljson` as and input and output format. This allows pandoc to convert between `csljson` and other bibliography formats, and to generate formatted versions of CSL JSON bibliographies. * Add module Text.Pandoc.Writers.CslJson, exporting `writeCslJson`. [API change] * Add module Text.Pandoc.Readers.CslJson, exporting `readCslJson`. [API change] * Added `bibtex`, `biblatex` as input formats. This allows pandoc to convert between BibLaTeX and BibTeX and other bibliography formats, and to generated formatted versions of BibTeX/BibLaTeX bibliographies. * Add module Text.Pandoc.Readers.BibTeX, exporting `readBibTeX` and `readBibLaTeX`. [API change] * Make "standalone" implicit if output format is a bibliography format. This is needed because pandoc readers for bibliography formats put the bibliographic information in the `references` field of metadata; and unless standalone is specified, metadata gets ignored. (TODO: This needs improvement. We should trigger standalone for the reader when the input format is bibliographic, and for the writer when the output format is markdown.) * Carry over `citationNoteNum` to `citationNoteNumber`. This was just ignored in pandoc-citeproc. * Text.Pandoc.Filter: Add `CiteprocFilter` constructor to Filter. [API change] This runs the processCitations transformation. We need to treat it like a filter so it can be placed in the sequence of filter runs (after some, before others). In FromYAML, this is parsed from `citeproc` or `{type: citeproc}`, so this special filter may be specified either way in a defaults file (or by `citeproc: true`, though this gives no control of positioning relative to other filters). TODO: we need to add something to the manual section on defaults files for this. * Add deprecation warning if `upandoc-citeproc` filter is used. * Add `--citeproc/-C` option to trigger citation processing. This behaves like a filter and will be positioned relative to filters as they appear on the command line. * Rewrote the manual on citatations, adding a dedicated Citations section which also includes some information formerly found in the pandoc-citeproc man page. * Look for CSL styles in the `csl` subdirectory of the pandoc user data directory. This changes the old pandoc-citeproc behavior, which looked in `~/.csl`. Users can simply symlink `~/.csl` to the `csl` subdirectory of their pandoc user data directory if they want the old behavior. * Add support for CSL bibliography entry formatting to LaTeX, HTML, Ms writers. Added CSL-related CSS to styles.html.

2020-09-13HTML writer: support intermediate table headersAlbert Krewinkel1-4/+10
Closes: #6314
2020-09-13HTML writer: support attributes on all table elementsAlbert Krewinkel1-6/+10
Add attributes to tbody and tr elements.
2020-09-13Fix hlint suggestions, update hlint.yaml (#6680)Christian Despres1-2/+1
* 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.
2020-09-12HTML writer: render table footers if presentAlbert Krewinkel1-23/+50
Part of: #6314
2020-09-12[API change] Rename Writers.Tables and its contents (#6679)Christian Despres1-20/+20
Writers.Tables is now Writers.AnnotatedTable. All of the types and functions in it have had the "Ann" removed from them. Now it is expected that the module be imported qualified.
2020-09-10Support colspans and rowspans in HTML tables (#6644)Albert Krewinkel1-65/+187
* HTML writer: add support for row headers, colspans, rowspans * Add planet table tests See #6312
2020-08-21HTML writer: Fix addition of doc-biblioentry role.John MacFarlane1-1/+1
2020-07-01HTML writer: improve alt-text/caption handling for HTML5Albert Krewinkel1-2/+10
Screen readers read an image's `alt` attribute and the figure caption, both of which come from the same source in pandoc. The figure caption is hidden from screen readers with the `aria-hidden` attribute. This improves accessibility. For HTML4, where `aria-hidden` is not allowed, pandoc still uses an empty `alt` attribute to avoid duplicate contents. Closes: #6491
2020-05-30Change default revealjs-url to use CDN version of revealjs v4.John MacFarlane1-1/+1
See #6408.
2020-05-28Fixed Katex standalone script (#6399)Lucas Escot1-0/+2
Global macros are now persistent when using the HTML Writer with the --katex option.
2020-05-18Use CSS in favor of <br> for display math (#6372)Lila1-13/+10
Some CSS to ensure that display math is displayed centered and on a new line is now included in the default HTML-based templates; this may be overridden if the user wants a different behavior.
2020-04-28Support new Underline element in readers and writers (#6277)Vaibhav Sagar1-0/+1
Deprecate `underlineSpan` in Shared in favor of `Text.Pandoc.Builder.underline`.
2020-04-18Fix round-trip bug with HTML tables....John MacFarlane1-9/+13
introduced by parsing of table attributes. (The writer always added a style with width, and we would get multiple such styles through successive round trips.)
2020-04-15Adapt to the newest Table type, fix some previous adaptation issuesdespresc1-1/+1
- 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.

2020-03-22Finer grained imports of Text.Pandoc.Class submodules (#6203)Albert Krewinkel1-2/+2
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.
2020-03-15Use implicit Prelude (#6187)Albert Krewinkel1-2/+0
* 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.
2020-03-13Update copyright year (#6186)Albert Krewinkel1-1/+1
* Update copyright year * Copyright: add notes for Lua and Jira modules
2020-02-13A bit more cleanup (#6141)Joseph C. Sible1-1/+1
* Remove unnecessary fmaps and only do toMilliseconds once * Share the input tuple intead of making a new one * Lift return out of if * Simplify case statements * Lift DottedNum out of the case statements * Use st instead of mbs * Use setState instead of updateState now that we have the whole state around
2020-02-12Moved html5Attributes, html4Attributes, rdfaAttributes...John MacFarlane1-347/+2
from T.P.Writers.HTML (where they were unexported) to T.P.XML (where they are now exported). [API change: new exported functions] This allows these sets to be used elsewhere, e.g. in the HTML reader.
2020-02-08reveal.js: ensure that pauses work even in title slides.John MacFarlane1-4/+6
Closes #5819.
2020-02-07Apply linter suggestions. Add fix_spacing to lint target in Makefile.John MacFarlane1-4/+4
2020-02-05Fix --number-offset with HTML TOC.John MacFarlane1-10/+19
Eventually it would be worth adding a parameter to makeSections so this could be done at that level; then it would also affect other writers that construct TOC manually.
2020-01-12HTML writer: fix duplicate attributes on headings.John MacFarlane1-9/+10
Another regression from 2.7.x. Closes #6062.
2020-01-07Reveal.js writer: restore old behavior for 2D nesting.John MacFarlane1-11/+17
The fix to #6030 actually changed behavior, so that the 2D nesting occurred at slide level N-1 and N, instead of at the top-level section. This commit restores the 2.7.3 behavior. If there are more than 2 levels, the top level is horizontal and the rest are collapsed to vertical. Closes #6032.
2020-01-05Fix revealjs slide structure regression with certain slide levels.John MacFarlane1-6/+8
Partially addresses #6030.
2020-01-04HTML writer: Add newlines to make slide show output more readable.John MacFarlane1-6/+8

having to do with makeSections.
2019-12-21Fix regression with --number-sections.John MacFarlane1-2/+1
Starting with 2.8, `--number-sections` also had the effect of `--section-divs`, even if `--section-divs` was not specified.
2019-12-17Improved makeSections so we don't get doubled attributes.John MacFarlane1-1/+2
Closes #5986.
2019-12-05HTML writer: add task-list class to ul if all elements are task list items.John MacFarlane1-1/+10
This will allow styling unordered task lists in a way that omits the bullet.

2019-11-12Switch to new pandoc-types and use Text instead of String [API change].despresc1-139/+138
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.
2019-11-11Change the implementation of `htmlSpanLikeElements` and implement `<dfn>` ↵Florian Beeres1-2/+4
(#5882) * Add HTML Reader support for `<dfn>`, parsing this as a Span with class `dfn`. * Change `htmlSpanLikeElements` implementation to retain classes, attributes and inline content.
2019-11-07Fix list fields in Opt so they aren't reversed.John MacFarlane1-2/+6
Previously optIncludeInHeader, etc. were in reverse order. This has been changed to promote #5881. Note also that the `sourcefile` variable used to be sometimes a string, sometimes a list (when there was more than one). Now it is always a list.
2019-11-04HTML Reader/Writer - Add support for <var> and <samp> (#5861)Amogh Rathore1-6/+15
Closes #5799
2019-10-29Changes to build with new doctemplates/doclayout.John MacFarlane1-3/+4
The new version of doctemplates adds many features to pandoc's templating system, while remaining backwards-compatible. New features include partials and filters. Using template filters, one can lay out data in enumerated lists and tables. Templates are now layout-sensitive: so, for example, if a text with soft line breaks is interpolated near the end of a line, the text will break and wrap naturally. This makes the templating system much more suitable for programatically generating markdown or other plain-text files from metadata.
2019-10-24HTML reader/writer: Better handling of <q> with cite attribute (#5837)Ole Martin Ruud1-2/+10
* HTML reader: Handle cite attribute for quotes. If a `<q>` tag has a `cite` attribute, we interpret it as a Quoted element with an inner Span. Closes #5798 * Refactor url canonicalization into a helper function * Modify HTML writer to handle quote with cite. [0]: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/q
2019-10-15Add support for reading and writing <kbd> elementsDaniele D'Orazio1-25/+39
* Text.Pandoc.Shared: export `htmlSpanLikeElements` [API change] This commit also introduces a mapping of HTML span like elements that are internally represented as a Span with a single class, but that are converted back to the original element by the html writer. As of now, only the kbd element is handled this way. Ideally these elements should be handled as plain AST values, but since that would be a breaking change with a large impact, we revert to this stop-gap solution. Fixes https://github.com/jgm/pandoc/issues/5796.

2019-09-08Replace Element and makeHierarchical with makeSections.John MacFarlane1-133/+100
Text.Pandoc.Shared: + Remove `Element` type [API change] + Remove `makeHierarchicalize` [API change] + Add `makeSections` [API change] + Export `deLink` [API change] Now that we have Divs, we can use them to represent the structure of sections, and we don't need a special Element type. `makeSections` reorganizes a block list, adding Divs with class `section` around sections, and adding numbering if needed. This change also fixes some longstanding issues recognizing section structure when the document contains Divs. Closes #3057, see also #997. All writers have been changed to use `makeSections`. Note that in the process we have reverted the change c1d058aeb1c6a331a2cc22786ffaab17f7118ccd made in response to #5168, which I'm not completely sure was a good idea. Lua modules have also been adjusted accordingly. Existing lua filters that use `hierarchicalize` will need to be rewritten to use `make_sections`.
