Attribute lists are represented as associative lists in Lua. Pure
associative lists are awkward to work with. A metatable is attached to
attribute lists, allowing to access and use the associative list as if
the attributes were stored in as normal key-value pair in table.
Note that this changes the way `pairs` works on attribute lists. Instead
of producing integer keys and two-element tables, the resulting iterator
function now returns the key and value of those pairs. Use `ipairs` to
get the old behavior.
Warning: the new iteration mechanism only works if pandoc has been
compiled with Lua 5.2 or later (current default: 5.3).
The `pandoc.Attr` function is altered to allow passing attributes as
key-values in a normal table. This is more convenient than having to
construct the associative list which is used internally.
Closes#4071
* Move as much as possible to the CSS in the template.
* Ensure that all the HTML-based templates (including epub)
contain the CSS for columns.
* Columns default to 50% width unless they are given a width
attribute.
Closes#4028.
The second argument of the OrderedList constructor, which should define
the list's attributes, is made optional. Default attributes are used if
the parameter is omitted.
Make Attr values accessible through through the keys `identifier`,
`classes` and `attributes`. This is already used in other elements with
attributes and is now fixed for Link and Image.
The pipe command is wrapped in a lua function, throwing a lua error if
the command returns with an error. A wrapper is needed as Haskell
functions exposed to lua may not throw lua errors due to limitations of
hslua.
The error handling is written such that a table can be returned as an
error object in the future. This is potentially useful when finer
control is required while catching the error in lua code. Current
limitations of hslua require error objects to be strings.
* Rename --latex-engine to --pdf-engine
* In `Text.Pandoc.Options.WriterOptions`, rename `writerLaTeXEngine` to `writerPdfEngine` and `writerLaTeXArgs` to `writerPdfArgs`.
* Add support for `weasyprint` and `prince`, in addition to `wkhtmltopdf`, for PDF generation via HTML (closes#3906).
* `Text.Pandoc.PDF.html2pdf`: use stdin instead of intermediate HTML file
We now use the default.latex template for both latex and beamer.
It contains conditionals for the beamer-specific things.
`pandoc -D beamer` will return this template.
Beamer loads `xcolor` rather than `color`, and thus the `dvipsnames` option doesn't take effect. This also provides a wider range of colour selections with the `svgnames` option. Closes#3877.
...by using the `luatexja-fontspec` and `luatexja-preset` packages. Use
existing `CJKmainfont` and `CJKoptions` template variables. Add
`luatexjafontspecoptions` for `luatexja-fontspec` and `luatexjapresetoptions`
for `luatexja-preset`.
Functions with a name that corresponds to an AST element are included in
implicit pandoc filter, but both `Meta` and `Pandoc` were wrongly
ignored till now.
The structure expected is:
<div class="columns">
<div class="column" width="40%">
contents...
</div>
<div class="column" width="60%">
contents...
</div>
</div>
Support has been added for beamer and all HTML slide formats.
Closes#1710.
Note: later we could add a more elegant way to create
this structure in Markdown than to use raw HTML div elements.
This would come for free with a "native div syntax" (#168).
Or we could devise something specific to slides
Avoids an options clash when loading a package (e.g. `tufte-latex`) that uses `hyperref` settings different from those in the template (introduced in <feffd7c64a>).
* readDataFile, readDefaultDataFile, getReferenceDocx,
getReferenceODT have been removed from Shared and
moved into Class. They are now defined in terms of
PandocMonad primitives, rather than being primitve
methods of the class.
* toLang has been moved from BCP47 to Class.
* NoTranslation and CouldNotLoudTranslations have
been added to LogMessage.
* New module, Text.Pandoc.Translations, exporting
Term, Translations, readTranslations.
* New functions in Class: translateTerm, setTranslations.
Note that nothing is loaded from data files until
translateTerm is used; setTranslation just sets the
language to be used.
* Added two translation data files in data/translations.
* LaTeX reader: Support `\setmainlanguage` or `\setdefaultlanguage`
(polyglossia) and `\figurename`.
Changed markdown, rtf, and HTML-based templates accordingly.
This allows you to set `toc: true` in the metadata; this
previously produced strange results in some output formats.
Closes#2872.
For backwards compatibility, `toc` is still set to the
toc contents. But it is recommended that you update templates
to use `table-of-contents` for the toc contents and `toc`
for a boolean flag.
* New module Text.Pandoc.Readers.Vimwiki, exporting readVimwiki [API change].
* New input format `vimwiki`.
* New data file, `data/vimwiki.css`, for displaying the HTML produced by this reader and pandoc's HTML writer in the style of vimwiki's own HTML export.
This is a thin wrapper around mathjax that makes math look better
on revealjs.
See https://github.com/hakimel/reveal.js/#mathjax
We do this by setting the 'mathjax' boolean variable and
using it in the revealjs template. Also, for revealjs
and mathjax, we don't assign the usual thing to the 'math'
variable, since it's handled by mathjax config.
Closes#3743.
