A new module `pandoc.utils` has been created. It holds utility functions
like `sha1`, which was moved from the main `pandoc` module.
|
|
It is no longer needed now that we have `--print-highlight-style`.
See #4096.
|
|
The `pipe` and `read` utility functions are converted from hybrid
lua/haskell functions into full Haskell functions. This avoids the need
for intermediate `_pipe`/`_read` helper functions, which have dropped.
|
|
This was a bug introduced in version 2.0.4 (commit
3f1f9536d4817bbdd797c01050a887fe4cdf347c).
|
|
The old template produced numbered sections with some recent
versions of beamer.
Thanks to Thomas Hodgson.
|
|
* Add pagestyle support
* Add pagestyle option to MANUAL.txt
* Moved mention of pagestyle to the section on variables

The file `init.lua` is used to initialize the Lua interpreter which is
used in Lua filters. This gives users the option to require libraries
which they want to use in all of their filters, and to extend default
modules.
|
|
The integration with Lua's package/module system is improved: A
pandoc-specific package searcher is prepended to the searchers in
`package.searchers`. The modules `pandoc` and `pandoc.mediabag` can now
be loaded via `require`.
|
|
This allows it to be styled more easily.
Closes #4120.

This ensures that we don't use $..$ delimiters, which
gives bad results when $ is used as a currency sign.
This depends on the current dev version of reveal.js.

The `List` metatable is assigned to the tables which get passed to the
constructors `MetaBlocks`, `MetaInline`, and `MetaList`. This enables
the use of the resulting objects as lists. This is part of the changes
discussed in #4081.
|
|
Pandoc and Meta elements are now pushed by calling the respective
constructor functions of the pandoc Lua module. This makes serialization
consistent with the way blocks and inlines are pushed to lua and allows
to use List methods with the `blocks` value.
|
|
The changes were missing due to an error while using git.
|

The List module is automatically loaded, but not assigned to a global
variable. It can be included in filters by calling `List = require
'List'`.
Lists of blocks, lists of inlines, and lists of classes are now given
`List` as a metatable, making working with them more convenient. E.g.,
it is now possible to concatenate lists of inlines using Lua's
concatenation operator `..` (requires at least one of the operants to
have `List` as a metatable):
function Emph (emph)
local s = {pandoc.Space(), pandoc.Str 'emphasized'}
return pandoc.Span(emph.content .. s)
end
Closes: #4081

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

Otherwise we seem to get an error; biblatex wants polyglossia
language to be defined.
Closes #4073.

They were being rendered twice, leading to invalid XML.
|
|
Reason: often etc. ends a sentence, and we want the . to
be treated as a sentence-ending period.

* 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.

see #3556

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.
|
|
A table containing the error code, command, and command output is thrown
instead of just a string error message.

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.

Otherwise they won't show up in current version of firefox/chromium.
|
|
This reduces some boilerplate.
|
|
This caused an error in beamer.
Footnotes already work in tables in beamer, without this code.

* 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
|
|
The textcomp package allows pdfLaTeX to parse `€` directly, making the \euro command unneeded. Closes #3801.
|
|
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.
|

Prevents changes to documents defined using the dvipsnames list (e.g. `Blue` gives a different result with svgnames enabled).
|
|
|
|
It needs to be loaded as late as possible.
Closes #3898.

Lua module documentation
|
|
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.
|
|
|
|
All conditionals use the `beamer` variable set by the writer.
Closes #3878.
|
|
...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`.
|
|
Try function `Inline`/`Block` if no other filter function of the
respective type matches an element.
Closes: #3859
|
|
So we don't have a dangling line with the closing `>` when
`lang` is not set.
|
|
|
|
Multiple documentation mistakes were fixed.
|
|
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
