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.
Previously we computed the column sizes based on the ratio
between the header lines and the text width (as set by `--columns`).
This meant that tables with very short header lines would be
very narrow. With this change, pipe tables with wrapping cells will
always take up the whole text width. The relative column widths
will still be determined by the ratio of header lines, but they
will be normalized to add up to 1.0.
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 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`.
* Deprecate `--strip-empty-paragraphs` option. Instead we now
use an `empty_paragraphs` extension that can be enabled on
the reader or writer. By default, disabled.
* Add `Ext_empty_paragraphs` constructor to `Extension`.
* Revert "Docx reader: don't strip out empty paragraphs."
This reverts commit d6c58eb836.
* Implement `empty_paragraphs` extension in docx reader and writer,
opendocument writer, html reader and writer.
* Add tests for `empty_paragraphs` extension.
We now have the `--strip-empty-paragraphs` option for that,
if you want it. Closes#2252.
Updated docx reader tests.
We use stripEmptyParagraphs to avoid changing too
many tests. We should add new tests for empty paragraphs.
Previously both needed to be specified (unless the image was
being resized to be smaller than its original size).
If height but not width is specified, we now set width to
textwidth (and similarly if width but not height is specified).
Since we have keepaspectratio, this yields the desired result.
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
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
