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 * PandocMonad: remove outdated check for base version Only base versions 4.9 and later are supported, the check for `MIN_VERSION_base(4,8,0)` is therefore unnecessary.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
2019-12-21HTML writer: more tweaks to avoid round-trip failures...John MacFarlane1-2/+5
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.

2019-10-09Options.WriterOptions: Change type of writerVariables to Context Text.John MacFarlane1-4/+7
This will allow structured values. [API change]
2019-09-28Use Prelude.fail to avoid ambiguity with fail from GHC.Base.John MacFarlane1-1/+1
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`.
2019-09-02HTML writer: use numeric character references with `--ascii`.John MacFarlane1-6/+2
Previously we used named character references with html5 output. But these aren't valid XML, and we aim to produce html5 that is also valid XHTML (polyglot markup). (This is also needed for epub3.) Closes #5718.
2019-08-25Use new doctemplates, doclayout.John MacFarlane1-18/+21
+ Remove Text.Pandoc.Pretty; use doclayout instead. [API change] + Text.Pandoc.Writers.Shared: remove metaToJSON, metaToJSON' [API change]. + Text.Pandoc.Writers.Shared: modify `addVariablesToContext`, `defField`, `setField`, `getField`, `resetField` to work with Context rather than JSON values. [API change] + Text.Pandoc.Writers.Shared: export new function `endsWithPlain` [API change]. + Use new templates and doclayout in writers. + Use Doc-based templates in all writers. + Adjust three tests for minor template rendering differences. + Added indentation to body in docbook4, docbook5 templates. The main impact of this change is better reflowing of content interpolated into templates. Previously, interpolated variables were rendered independently and intepolated as strings, which could lead to overly long lines. Now the templates interpolated as Doc values which may include breaking spaces, and reflowing occurs after template interpolation rather than before.
2019-07-28Use doctemplates 0.3, change type of writerTemplate.John MacFarlane1-1/+1
* Require recent doctemplates. It is more flexible and supports partials. * Changed type of writerTemplate to Maybe Template instead of Maybe String. * Remove code from the LaTeX, Docbook, and JATS writers that looked in the template for strings to determine whether it is a book or an article, or whether csquotes is used. This was always kludgy and unreliable. To use csquotes for LaTeX, set `csquotes` in your variables or metadata. It is no longer sufficient to put `\usepackage{csquotes}` in your template or header includes. To specify a book style, use the `documentclass` variable or `--top-level-division`. * Change template code to use new API for doctemplates.
2019-07-24HTML writer: ensure TeX formulas are rendered correctly (#5658)Philip Pesca1-1/+1
The web service passed in to `--webtex` may render formulas using inline or display style by default. Prefixing formulas with the appropriate command ensures they are rendered correctly. This is a followup to the discussion in #5656.
2019-07-23HTML writer: render inline formulas correctly with --webtex (#5656)Philip Pesca1-1/+4
We add `\textstyle` to the beginning of the formula to ensure it will be rendered in inline style. Closes #5655.
2019-07-18HTML writer: ensure that line numbers in code blocks get id-prefix.John MacFarlane1-3/+5
Closes #5650.
2019-07-12Pass through aria- attributes to HTML5.John MacFarlane1-0/+1
Also document addition of data- prefix to unknown attributes. Closes #5646.

2019-05-28HTML writer: emit empty alt tag in figures (#5518)Mauro Bieg1-1/+1
The same text is already in the <figcaption> and screen-readers would read it twice, see #4737
2019-05-04HTML writer: don't add variation selector if it's already there.John MacFarlane1-1/+4
See f11d0c9dc8b61cc38e138aaecb0f0094add3465a This fixes round-trip failures.
2019-04-30HTML: prevent gratuitious emojification on iOS.John MacFarlane1-1/+10
iOS chooses to render a number of Unicode entities, including '↩', as big colorful emoji. This can be defeated by appending Unicode VARIATION SELECTOR-15'/'VARIATION SELECTOR-16'. So we now append this character when escaping strings, for both '↩' and '↔'. If other characters prove problematic, they can simply be added to needsVariationSelector. Closes #5469.
2019-04-20HTML writer: Add class="heading" to level 7+ Headers...John MacFarlane1-1/+1

2019-03-28HTML writer: Don't add data- prefix to RDFa attributes.John MacFarlane1-2/+19
Closes #5403.
2019-03-01HTML writer: include content under title slides.John MacFarlane1-7/+9
This facilitates real 2D revealjs slideshows, with content under the top-level slide in each stack. It also enables notes on title slides. Closes #4317 and #5237.
2019-03-01Remove license boilerplate.John MacFarlane1-18/+0
The haddock module header contains essentially the same information, so the boilerplate is redundant and just one more thing to get out of sync.
2019-02-10Implement aria roles doc-bibliography, doc-biblioentry, doc-biblioref.John MacFarlane1-2/+10
Note that doc-biblioref is only used when link-citations produces links, since it belongs on links. See #4213.
2019-02-04Add missing copyright notices and remove license boilerplate (#5112)Albert Krewinkel1-2/+2
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.
2019-02-02HTML5 writer: implement WAI-ARIA roles for (end)notes.John MacFarlane1-12/+25
See #4213.
2019-01-07revealjs writer: fix some section nesting corner cases.John MacFarlane1-6/+13
* Ensure that we don't get > 2 levels of section nesting, even with slide level > 2. * If slide level == N but there is no N-level header, make sure the next header with level > N gets treated as a slide and put in a section, rather than remaining loose. Closes #5168.
