* 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
This fixes a bug where pandoc would stop parsing a URI with an
empty attribute: for example, `&a=&b=` wolud stop at `a`.
(The uri parser tries to guess which punctuation characters
are part of the URI and which might be punctuation after it.)
Closes#4068.
