The resulting PDF can be verified using the Apache PDFBox preflight app.
```
$ java -jar preflight-app-2.0.8.jar test.pdf
The file test.pdf is a valid PDF/A-1b file
```
Instructions on how to install the ICC profiles on ConTeXt standalone can be found in the wiki: <http://wiki.contextgarden.net/PDFX#ICC_profiles>.
If the ICC profiles are not available the log will contain messages like these
```
backend > profiles > profile specification 'sRGB.icc' loaded from '/usr/local/texlive/2017/texmf-dist/tex/context/colors/icc/context/colorprofiles.xml'
backend > profiles > error, couldn't locate profile 'srgb.icc'
backend > profiles > no default profile 'srgb.icc' for colorspace 'rgb'
backend > profiles > profile specification 'sRGB IEC61966-2.1' loaded from '/usr/local/texlive/2017/texmf-dist/tex/context/colors/icc/context/colorprofiles.xml'
backend > profiles > error, couldn't locate profile 'srgb.icc'
backend > profiles > invalid output intent 'sRGB IEC61966-2.1'
```
and the resulting PDF will not be valid PDF/A:
```
$ java -jar preflight-app-2.0.8.jar test.pdf
The file test.pdf is not a valid PDF/A-1b file, error(s) :
2.4.3 : Invalid Color space, The operator "g" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, The operator "G" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, /DeviceGray default for operator "TJ" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, /DeviceGray default for operator "TJ" can't be used without Color Profile on page 1

```
However, the PDF will still be generated and the "errors" shown in the log do not break anything.

* Provide `bidi` package's option using `\PassOptionsToPackage`. This avoid clash when `polyglossia` loads it first and then it is loaded again for XeLaTeX when `latex-dir-rtl` defined.
* Adjust test suite for LaTeX template change.

This used to be needed prior to v 0.8 of docutils, but
now math support is built-in.

Ms writer: Added papersize variable

- Default to xtables for context output.
- Added `ntb` extension (affecting context writer only) to use Natural Tables instead.
- Added `Ext_ntb` constructor to `Extension` (API change).

Elements with attributes got an additional `attr` accessor. Attributes
were accessible only via the `identifier`, `classes`, and `attributes`,
which was in conflict with the documentation, which indirectly states
that such elements have the an `attr` property.
|
|
Every constructor which accepts a list of blocks now also accepts a
single block element for convenience. Furthermore, strings are accepted as
shorthand for `{pandoc.Str "text"}` in constructors.
|
|
Every constructor which accepts a list of inlines now also accepts a
single inline element for convenience.
|
|
Having a _VERSION became superfluous, as this module is closely tied to
the pandoc version, which is available via PANDOC_VERSION.
|
|
Accessing an Attr value (e.g., ` Attr().classes`) was broken; the more
common case of accessing it via an Inline or Block element was
unaffected by this.

Attr is an AST element, which is now reflected in the type hierarchy.
|
|
This attribute was out-of-sync with the actual version as is mostly
irrelevant in the context Lua filters and custom writers. Use the
global `PANDOC_API_VERSION` instead.
|
|
*Pandoc*, *Meta*, and *Citation* were just plain functions and did not
set a metatable on the returned value, which made it difficult to amend
objects of these types with new behavior. They are now subtypes of
AstElement, meaning that all their objects can gain new features when a
method is added to the behavior object (e.g., `pandoc.Pandoc.behavior`).
|
|
Clearly distinguish between a type and the behavioral properties of an instance
of that type. The behavior of a type (and all its subtypes) can now be amended
by adding methods to that types `behavior` object, without exposing the type
objects internals.
E.g.:
pandoc.Inline.behavior.frob = function () print'42' end
local str = pandoc.Str'hello'
str.frob() -- outputs '42'
|
|
This avoids confusion with the Element type from Text.Pandoc.Shared.
Change: minor
|
|
A `Element:new` method was a left-over was never called.
Change: minor
|
|
Extending all elements of a given type (e.g., all inline elements) was
difficult, as the table used to lookup unknown methods would be reset
every time a new element of that type was created, preventing recursive
property lookup. This is was changed in that all methods and attributes
of supertypes are now available to their subtypes.
|
|
|
|
The fields were named like the Haskell fields, not like the documented,
shorter version. The names are changed to match the documentation and
Citations are given a shared metatable to enable simple extensibility.
Fixes: #4222

The function `global_filter` was used internally to get the implicitly
defined global filter. It was of little value to end-users, but caused
unnecessary code duplication in pandoc. The function has hence been
dropped. Internally, the global filter is now received by interpreting
the global table as lua filter.
This is a Lua API change.
|
|
|
|
|
|
Each definition list item contains just a single key and the associated
value. Using `next` to get the key/value pair is more idiomatic than
iterating over the single-element table.

This reverts commit 0e3736422ee97a5cfedc255705f566a319f954f9
in favor of @tarleb's fix.
|
|
Closes #4202.
|
|
|
|
Instead of just "Hello, world", the document now contains
exemplars of most of the styles that have an effect on pandoc
documents.
This makes it easier to see the effect of style changes.
Closes #4175.
|
|
instead of relying on CSS. Closes #4162. HTML-based templates have had
the custom CSS for div.line-block removed. Those maintaining custom
templates will want to remove this too.
We still enclose line blocks in a div with class line-block.
|

|
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.
