2020-12-20LaTeX writer: support colspans and rowspans in tables. (#6950)Albert Krewinkel1-2/+4
Note that the multirow package is needed for rowspans. It is included in the latex template under a variable, so that it won't be used unless needed for a table.
2020-12-12LaTeX writer: extract table handling into separate module.Albert Krewinkel1-237/+12
2020-12-04LaTeX writer: Fix bug with nested csl- display Spans.John MacFarlane1-36/+32
See #6921.
2020-11-25LaTeX writer: improve longtable output.John MacFarlane1-40/+60
- Don't create minipages for regular paragraphs. - Put width and alignment information in the longtable column descriptors. - Closes #6883.
2020-11-25LaTeX tables: Fix calculation of column spacing.John MacFarlane1-1/+1
See #6883.
2020-11-22LaTeX writer: Improve table spacing.John MacFarlane1-2/+2
+ Remove the `\strut` that was added at the end of minipage environments in cells. + Replace `\tabularnewline` with `\\ \addlinespace`. Closes #6842, closes #6860.
2020-10-29LaTeX writer: Improved calculation of table column widths.John MacFarlane1-10/+12
We now have LaTeX do the calculation, using `\tabcolsep`. So we should now have accurate relative column widths no matter what the text width. The default template has been modified to load the calc package if tables are used.
2020-10-14Modify fix to #6742 to use stringToLaTeX.John MacFarlane1-3/+5
2020-10-13LaTeX writer: escape option values in lstlistings environment.John MacFarlane1-1/+2
Closes #6742.
2020-10-12LaTeX writer: fix handling of pt-BR.John MacFarlane1-3/+2
For polyglossia we now use `\setmainlanguage[variant=brazilian]{portuguese}` and for babel `\usepackage[shorthands=off,main=brazilian]{babel}`. Closes #2953.
2020-09-21Add built-in citation support using new citeproc library.John MacFarlane1-11/+32
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.
2020-09-15LaTeX writer: fix spacing issue with list in definition list.John MacFarlane1-3/+20
When a list occurs at the beginning of a definition list definition, it can start on the same line as the label, which looks bad. Fix that by starting such lists with an `\item[]`.
2020-09-13Fix hlint suggestions, update hlint.yaml (#6680)Christian Despres1-6/+6
* 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.
2020-06-17LaTeX writer: escape `^` specially for listings.John MacFarlane1-1/+1
Closes #6460.
2020-06-14Distinguish between single and double quotes when using enquote package (#6457)dbecher-ito1-1/+3
2020-05-12LaTeX writer: create hypertarget for links with identifier.John MacFarlane1-23/+27
Closes #6360.
2020-05-02LaTeX Writer: Add support for customizable alignment of columns in beamer ↵andrebauer1-5/+24
(#6331) Add support for customizable alignment of columns in beamer. Closes #4805, closes #4150.
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`.
2020-04-15Adapt 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.
2020-04-15Implement the new Table typedespresc1-1/+2
2020-04-11LaTeX writer: ensure that `-M csquotes` works even in fragment mode.John MacFarlane1-10/+11
Closes #6265.
2020-03-22Finer grained imports of Text.Pandoc.Class submodules (#6203)Albert Krewinkel1-1/+1
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
2020-02-14Fixes: group biblatex citations even with prefix and suffix (#6058)Ethan Riley1-25/+42
Closes #5849. Previously biblatex citations were only grouped if there was no prefix. This patch allows them to be grouped in subgroups split by prefixes and suffixes, which allows better citation sorting.
2020-02-07Apply linter suggestions. Add fix_spacing to lint target in Makefile.John MacFarlane1-4/+2
2020-02-07Resolve HLint warningsAlbert Krewinkel1-6/+5
All warnings are either fixed or, if more appropriate, HLint is configured to ignore them. HLint suggestions remain. * Ignore "Use camelCase" warnings in Lua and legacy code * Fix or ignore remaining HLint warnings * Remove redundant brackets * Remove redundant `return`s * Remove redundant as-pattern * Fuse mapM_/map * Use `.` to shorten code * Remove redundant `fmap` * Remove unused LANGUAGE pragmas * Hoist `not` in Text.Pandoc.App * Use fewer imports for `Text.DocTemplates` * Remove redundant `do`s * Remove redundant `$`s * Jira reader: remove unnecessary parentheses
2020-02-03Fix duplicate frame classes in LaTeX/Beamer output.John MacFarlane1-2/+2
Close #6107.
2020-01-07Fix regression in handling of columns in beamer slides.John MacFarlane1-5/+6
Columns in title slides were causing problems with slide division. Closes #6033.
2020-01-05Fix regression in beamer slide structure with certain slide levels.John MacFarlane1-8/+17
Closes #6030.
2020-01-01LaTeX writer: properly handle unnumbered headings level 4+.John MacFarlane1-1/+1
Closes #6018. Previously the `\paragraph` command was used instead of `\paragraph*` for unnumbered level 4 headings.
2019-11-27Remove redundant import.John MacFarlane1-1/+0
2019-11-27LaTeX writer - hlint.John MacFarlane1-29/+24
2019-11-12Switch to new pandoc-types and use Text instead of String [API change].despresc1-179/+193
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.
2019-10-29Changes to build with new doctemplates/doclayout.John MacFarlane1-2/+2
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.
2019-10-25Beamer writer: fix regression with hrules separating slides.John MacFarlane1-3/+3
2019-10-12LaTeX writer: fix horizontal rule.John MacFarlane1-1/+1
We change to use 0.5pt rather than `\linethickness`, which apparently only ever worked "by accident" and no longer works with recent updates to texlive. Closes #5801.
2019-10-10Make some writers sensitive to 'unlisted' class on headings.John MacFarlane1-4/+6
If this is present on a heading with the 'unnumbered' class, the heading won't appear in the TOC. This class has no effect if 'unnumbered' is not also specified. This affects HTML-based writers (including slide shows and epub), LateX (including beamer), RTF, and PowerPoint. Other writers do not yet support `unlisted`. Closes #1762.
2019-10-09Options.WriterOptions: Change type of writerVariables to Context Text.John MacFarlane1-3/+5
This will allow structured values. [API change]
2019-09-18LaTeX writer: use `\hspace{0pt}` for 0-width space U+200B.John MacFarlane1-0/+1
Closes #5756.
2019-09-08Replace Element and makeHierarchical with makeSections.John MacFarlane1-152/+131
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`.
2019-09-02LaTeX writer: use `cslreferences` environment for csl bibliographies.John MacFarlane1-3/+18
this allows bibliographies to receive special formatting. The template now contains definition of this environment (enabled only when CSL is used). It also defines a `\cslhangindent` length. This is set to 2em by default when the bibliography style specifies a hanging indent. To override the length, you can use e.g. \setlength{\cslhangindent}{7em} in header-includes. Closes jgm/pandoc-citeproc#410.
2019-09-02LaTeX writer: strip off `{}` around locator for biblatex/natbib output.John MacFarlane1-1/+7
Closes #5722.
2019-08-25Use new doctemplates, doclayout.John MacFarlane1-55/+66
+ 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.
2019-08-14Add thin space when needed in LaTeX quote ligatures.John MacFarlane1-4/+9
Closes #5685.
2019-07-28Use doctemplates 0.3, change type of writerTemplate.John MacFarlane1-44/+15
* 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.
2019-07-20LaTeX writer: fix line breaks at start of paragraph.John MacFarlane1-9/+9
Previously we just omitted these. Now we render them using `\hfill\break` instead of `\\`. This is a revision of a PR by @sabine (#5591) who should be credited with the idea. Closes #3324.
2019-06-11LaTeX writer: Don't highlight code in headings.John MacFarlane1-3/+4
This causes compilation errors, and I don't know how to work around them. Closes #5574.
2019-06-10LaTeX writer: Use mbox to get proper behavior inside `\sout`.John MacFarlane1-6/+6
Closes #5529.
2019-06-07LaTeX writer: Include inline code attributes with `--listings`.John MacFarlane1-4/+12
Closes #5420.
