* Previously we ran all lua filters before JSON filters.
* Now we run filters in the order they are presented on the
command line, whether lua or JSON.
* The type of `applyFilters` has changed (incompatible API change).
* `applyLuaFilters` has been removed (incompatible API change).
* Bump version to 2.1.

This is the beginning of a test suite for the powerpoint
writer. Initial tests are for the number of slides.
Note that at the moment it does not test against corruption in
Microsoft PowerPoint; it just tests that certain outcomes work as
expected. More tests will be added.
This test framework uses the PandocPure monad introduced with Pandoc 2.0.
The level of headers in included files can be shifted to a higher level
by specifying a minimum header level via the `:minlevel` parameter. E.g.
`#+include: "tour.org" :minlevel 1` will shift the headers in tour.org
such that the topmost headers become level 1 headers.
Fixes: #4154
The org reader test file had grown large, to the point that editor
performance was negatively affected in some cases. The tests are spread
over multiple submodules, and re-combined into a tasty TestTree in the
main org reader test file.
The same init file (`data/init`) that is used to setup the Lua
interpreter for Lua filters is also used to setup the interpreter of
custom writers.lua.
Support writing <fig> and <table-wrap> elements with <title> and
<caption> inside them by using Divs with class set to on of
fig, table-wrap or cation. The title is included as a Heading
so the constraint on where Heading can occur is also relaxed.
Also leaves out empty alt attributes on links.
This fixes a bug in 2.0.4, whereby pandoc could not
read the theme files generated with `--print-highlight-style`.
It also fixes some CSS issues involving line numbers.
Highlighted code blocks are now enclosed in a div with class
sourceCode.
Highlighting CSS no longer sets a generic color for pre
and code; we only set these for class `sourceCode`.
This will close#4133 and #4128.
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`.
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
The `text` module is preloaded in lua. The module contains some UTF-8
aware string functions, implemented in Haskell. The module is loaded on
request only, e.g.:
text = require 'text'
function Str (s)
s.text = text.upper(s.text)
return s
end
Refactored some code from Text.Pandoc.Lua.PandocModule
into new internal module Text.Pandoc.Lua.Filter.
Add `walk_inline` and `walk_block` in pandoc lua module.
The line identifiers are built using the code block's identifier
as a prefix. If the code block has null identifier, we use
"cb1", "cb2", etc.
Closes#4031.
