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.
* Create a type synonym for MIME type (instead of `String`).
* Add `getMimeTypeDef` function.
* Avoid recreating MIME type `Map`s every time.
* Move “Formula-...” case handling into `getMimeType`.
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.
