Build dependencies of the trypandoc executable are required, regardless of the
trypandoc flag was set to either True or False. Correct package description
to make them truly optional.
Also, if page-progression-direction not specified in metadata,
don't include the attribute even in EPUB3; not including it is
the same as including it with the value "default", as we did before.
Closes#1550.
Previously a section like this would be enclosed in a paragraph,
with RawInline for the video tags (since video is a tag that can
be either block or inline):
<video controls="controls">
<source src="../videos/test.mp4" type="video/mp4" />
<source src="../videos/test.webm" type="video/webm" />
<p>
The videos can not be played back on your system.<br/>
Try viewing on Youtube (requires Internet connection):
<a href="http://youtu.be/etE5urBps_w">Relative Velocity on
Youtube</a>.
</p>
</video>
This change will cause the video and source tags to be parsed
as RawBlock instead, giving better output.
The general change is this: when we're parsing a "plain" sequence
of inlines, we don't parse anything that COULD be a block-level tag.
We always favor an explicit positive or negative in a style in a
descendent, and only turn to the ancestor if nothing is set.
We also introduce an (empty) list of styles that are black-listed. We
won't check them. (Think underlines in hyperlinks).
Two points here: (1) We're going bottom-up, from styles not based on
anything, to avoid circular dependencies or any other sort of
maliciousness/incompetence. And (2) each style points to its
parent. That way, we don't need the whole tree to pass a style over to
Docx.hs
This cause problems on Windows 8, where the variable is called
`Path`.
Instead, simply trap the exception that will be raised by
`findExecutable` if path is not set.
This should fix#1542.
We want to be able to read user-defined styles. Eventually we'll be able
to figure out styles in terms of inheritance as well. The actual
cascading will happen in the docx reader.
In docx, super- and subscript are attributes of Vertalign. It makes more
sense to follow this, and have different possible values of Vertalign in
runStyle. This is mainly a preparatory step for real style parsing,
since it can distinguish between vertical align being explicitly turned
off and it not being set.
In addition, it makes parsing a bit clearer, and makes sure we don't do
docx-impossible things like being simultaneously super and sub.
